----
Hi, I'm been working on my terminal based unicode diagram editor [tinytools](https://github.com/minimapletinytools/tinytools-vty) for about 4 years now 😱. It's been ready to release for some time now but I keep putting it off and adding more features instead! But no more!!

I'm a complete potato when it comes to OSS release/distribution/promotion. Looking for tips/suggestions on other ways to distribute this app.

At the very least, I'll put a binary on github, and upload the latest to cabal, but I'd like it to be easier for folks to use the app.

I've done all my development on mac, so homebrew is a logical choice, however I'm a little concerned of the super long build times as well as the dependency on [https://hackage.haskell.org/package/text-icu](https://hackage.haskell.org/package/text-icu) which cabal often struggles to find.

I haven't thought about windows and linux but I'd like to release there as well.
And I haven't a clue on how to promote this besides making random reddit posts like this one. The software excels in its niche IMO so I expect it to ultimately promote itself for people who care, but I'd love to help push it along.

Thanks in advance.

:: glyph widget spec ::
-unicode char / full art
  -should single unicode be separate or no?
  -for unicode, how do handle grapheme clusters?
    -maybe just encourage folks to use OS-level picker instead?
-allow option to embed in definition file if height is only 1
-toggle option to search for only single char vs art
-separate file for single char glyph database maybe?
character_glpyhs


:: swatch spec ::

:: FUTURE FEATURES
IGNORE-grapheme cluster
  -terminals don't support it but browser will
  -for terminals, you need grapheme cluster detection to remove those chars
  -you may as well add unicode detections as well
  -need to update style types to take Text instead of Char to support grapheme clusters
DONE-EMOJIS
DONE-moveable line anchors
DONE-adjustable attachment spec
-support more shapes
  -diamond
  -ellipse
  -probably needs now styling classes, these should probably be presentsonly
-straight line tool spec
  -same as autoline (with midpoints) but has fancy line rendering straight lines
  -line style picker
-unicode character picker
  -lives at params level
  -must have a way to paste into text box
-clipart  picker
  -can choose to generate as text box or free art box
  -create link with orignal until modify?
  -format for user submitted clipart (prob just read from text file)
-swatches
-fancy type spec
  -property of text box, allow you to enter fancy fonts
  -other features
    -per character width (already a property of TextZipper but you need to pass it in as a function and test it...)
    -kerning in general (or just have user use manual spaces)
    -height adjustment (some characters go over char box)
    -overflow box or crop (some characters go over char box
      -need to expand render box
    -font data type
      -bonus, it seme some fonts have speical rules for renfdering where the font overlaps
    -font picker...
-segment style multipoint line spec
-scripting and extensions lol
-background pattern fills
  -crop or stop at end of last repeating pattern
-would be cool to have a way to manipulate multiple line midpoints at the same time
  -but really you should just switch to segment based midpoints instead..?
-multi-goat
-multi-shepard
-no partial owls!
  -except when converting remote changes to llamas



:: MDI REFACTOR NOTES 7/2023
IGNORE!!-get rid of PFWorkspace first
  DONE-get rid of lastChanges
  YES-or do we keep it? could be nic eplace to store preview list and local llama stack
DONE-handlers should return preview action
  -review pRefreshHandler as it will now take update cations
  -preview start, preview continue, preview commit, preview cancel
    -preview continue is prob unecessary, sending another preview start should implicitly cancel the last preview, but having it as an explicit state might still be nice
  -get rid of undofirst stuff
-goat changes
  -goat has preview list for each user
  DONE-goat has commit preview operation
  DONE-you can just directly preview commit to apply an operation without having preview I guess, or have a separate function to apply operation directly which might help with organization
  -preview commit could fail
    -a client might try and commit a preview that was invalidated 
  -goat needs to be able to apply several state changes,
    -do I need to make any changes to the SuperOwlChanges stuff?
      -probably union them all should just be fine, might have some useless info (i.e. do/undo one operation would leave an entry but didn't make any changes) in it but that's not a big deal.
-state changes
  -state needs to track preview changes to roll them back and reapply them when applying remote finalized changes 
  -state needs to track pending (commit but not finaized) changes i.e. CLIENT ROLLBACK so that commit operations can be applied locally and then sent to the network, but these might get overidden by the server
      -but this allows you to previwe->apply many operations before receiving updates so this is just better.
  -state needs to track change id/# (no # for preview changes)
-edge cases
  -handler in middle of preview operation and state update (i.e. refreshing an active handler)
    -in this case the refresh might return a preview cancel operation
  -conflicting previews
  -attaching to something that gets deleted
    -we do support attachment to deleted elt right now at the state level, not sure if it's supported at the handler level
  -how to handler layers hide/lock?
    -note these are not managed as llama actions weird!
    -prob easiest just to cancel any previews if anything gets lock/hidden, but maybe we can try and allow the preivew operation to complete, not sure if this is already done or super hard, could eb either!
    -however for undo/redo should be able to bypass
-llamastack updates
  -undo redo might fail if REltId does not exist. 
    -note that non-set llama changes do not contain a copy of the element so we can't just recreate it.
      -but maybe we can store a copy of the entire element to adjust for these cases?
      -but IMO maybe easier just to fail the whole do/undo operation in this case
        -gosh sure sucks if collaborator deletes a whole bunch of stuff though?
  -do we care that we are undo/redo overriding other peoples changes?
    -should be OK with fine grained changes
-will commute op1 op2
  -note that if op1 and op2 commute, we hope/expect op1 op2' to commute where op2' is a continuation of op2. But this isn't even strictly necessary and pRefreshHandler should just cancel the operation if it does not commute with some newly added operation
-need to create fine grain updaters rather than ones that set the entire owl to allow for better commuting
  -in particular
    -we don't want property updates to conflict with transform updates
    -we don't want layer hirerachy changes to conflict with other operations
  -confirm if PFCMove/add/delete is ok
  -the CTag PFCmd stuff needs to be redone as well as we want "set" style as oppose to deltas which don't play well if other changes had been applied on top of th particular fine grained change
  -The SLlama_Set stuff needs to be rewritten. Make like a SLlama_Update type deeal
-need to build multi-preview store inside of goat
  -???what happens when 2 previews conflict???
    -one person should just have their action cancelled I guess
      -sucks that you can lock out the entire scene by drag dropping everything
-soft locking elements that are being updated by other users?
  -we don't want to block selection because that would suck and we don't want to block params/layers update from other move operations
  -so I guess it's really just bblocking drag operations if someone else is dragging anything in our selection?
-highlight other user selection please
  -oof, need to make selection rendering a list??
    -maybe we can add color to the rendering? And combine it all selection into 1 renderer??
      -nah, probbaly better just to have separate renderer for each person
-Maybe there can be fine grain change history that lets you selectively undo and see who made what changes, that would be pretty cool!!!!
  -note the main issue here is that if there are a sequence of changes to the same fine-grained thing, it's weird to undo a change from a while ago, but maybe that's just how it is.
  -could store this is controller meta? Not really controller meta anymore though, so maybe create a separate object.. 
    -I mean PFWorkspace but I think it's better to store it side by side...
      -we do expect the state to be reconstructable from the change log so maybe it make sense to store it together with the state somehow?
-no conflict REltId generator
  -easiest just to go to 128 or 256 bits I guess....
-ordering service
  -preview -> Goat -> State
  -commit -> ordering service -> Goat -> State (rollback previews, apply commit change, apply reviews)
    -note this isn't e
  -consensus -> ordering service -> finalize commit -> Goat -> State (rollback previews, rollback commit state, apply finalized changes, apply unfinalized commits, apply previews)
  -consensus
    -just do hardcoded singel authority model for now, this also works well with the cloud model
    -need something sophisticated for P2P model :(, would be cool to do PBFT/PaLa but TBH raft is prob best since its tursted/permissioned
  -does ordering service need to know about state/non commuting changes
    -no it doesn't, goat can just toss out failed changes


:: SHAPE MVP
DONE-generalize object and manipulator refactor likely
  DONE-generalize text area 
    -return text area box
    -in the future, it could return per line widths :O
  DONE-generalize line connection points
    -connection points :: [(x,y)]
    -drag_project :: (x,y) -> Maybe (x,y)
  IGNORE-generalize Box handler bulk maniplutaion ???
    -you need to generalize this for lines too
DONE-shape selt
DONE-support label and text area
  -make BoxLabelHandler generic to shapes
  -make BoxTextHandler generic to shapes
  -finish ShapeModifyHandler when you do the above 2 thing
IGNORE-refactor ShapeDef please...
DONE-connect fully and deprecate BoxLabel/TextHandler
  -you can still keep BoxHandler for now as it does multi-select for you
DONE-make poopy ellipse drawer
DONE-add UTs
-add text area to ellipse, maybe add text label?
-make generic shape drawer
-add shape selection menu

:: shape tool spec
  -can we generalize box and boxtext handlers to support any shape
    -I think you need to consider refactoring box handler whichever way
      -NO I think you can just keep overloading...
    -parameterize the following
      -transform box -> shape -> transform box (when resizing)
      -shape -> Maybe text label position
      -shape -> Maybe text area 
      -shape -> starting attachment position
      -shape -> attachement projection function
      -shape -> drawing function
  -tool for creating non box shapes, must support resizing
    -allow snapping to only valid sizes?
      -however, should it remember what inbetween size it's at (when resizing multiple things) or no?
    -design generic format for doing shapes so easy to add custom shapes?
    -e.g. shapes
      -triangle
      -diamond
      -hexagon
      -octagon
      -circle/ellipse
      -3d cube (this might be a different handler? requires a 3rd degree of adjustment (could use box handler for creation, and separate handler for modify))
-generic shape render function
  -overlay square grid of shape paremeter
  -compute entry/exit on each square and assume line is straight
  -lookup closest unicode character matching the above
-secondary tools in tools
  -[(s)hape] selecting shows secondary list of choices
-some shapes maybe have special handlers that get activated after creation (creation is always using BoxHandler) e.g. triangle with moveable corners

::HIGH PRIORITY::
-BUG double: ()

    fromJust, called at src/Potato/Flow/Owl.hs:627:24 in tnytls-0.1.0.7-8994dabb:Potato.Flow.Owl
  repro: have folder with abunhc of element, select folder, copy paste folder (into itself, which is already little weird) and then drag inner folder outside of folder
-clean unused dependencies
  -figure out how to run dependency detector
-BUG one sided line broken
-should be more intuitive to get a 1 sided line
  -probably do [x] start | [x] end
  -default line can be one sided maybe?
  -make flip button more clear
-layers improvements
  -shift select in layers please ;__;
  -selecting multiple items and hitting new folder should put those items in folder maybe

::MID PRIORITY
-test/use PreRender stuff
-if both target and source of line is moved, then move midpoints as well
  -fix (search comment) -- THE REASON YOU DID THIS IS TO PREVENT FULLY ATTACHED LINES FROM BEING MOVED
  -in order to fix this, you need to change do_deleteElts to update position of attached lines which poses several issues:
    -need attachmentMap to do this optimally and it's currently stored in goatState
    -when you undo the delete, you ideally would set the line endpoint positions back to their original values (even if it's meaningless)
    -so you probably need to move delete into a llama operation where you can cache the original values in the returned undo operaiton
-file stuff
  -maybe highlight relevant files instead of * in file explorer
    -or just don't show anything that's not relevant...
  -UTs
    DONE-popupSaveBeforeExit
    DONE-popupOpenWindow
    -doubleClick
    DONE-waitForSecondAfterFirst (move to reflex-potatoes)
  DONE-add double click support to file explorer
    -need to hook into IO time stuff
-you should be able to select lines where there is text (this is in particular annoying when you try and move several things at once at you can't click on line label to move)
-move all serializable types into Snake for versioning
-folder stuff
  -maybe some day you want to implement folder select vs real select
    -would be cool to have the folder select OR real select option since folder select might be too much for terminal
  -BUG/FEATURE when you select a folder and it auto selects children, you can't click and drag the children
  -empty folders should not be expandable? (set to expanded by default)
  -BUG click release on lock/hide/collapse on selected element should not deselect
  -you might want to consider disallowing selection of locked stuff from folders (directly NOT ok, via parents OK)
  -maybe consider doing shift select and ctrl select (to replaec current shift select behavior)
    -not sure what happens when you shift select past a folder
-proper configurable theme in Main.hs
-rename
  -OwlPFWorkspace -> OwlWorkspace
  -OwlPFState -> OwlState
-upgrading ghc somehow broke unicode test
  -9.6 fails but 9.2 OK
-did scroll wheel in finder window stop working??
  -yes it's a fcous issue ,the mouse input does'nt get sent to the scroll wheel pane, you ned to pass it in if you want to fix it...
-undo_move is probably not very multi-user friendly, you should rewrite using do_move logic 
  -(so remove all children recursively and then add them back in)
  -(this will allow undo_move to work even if some of those childrens or parents have since been deleted I guess)
-shepard P2
  -you need to add a random generator to GoatState with sufficient entropy to generate Uuids
  -add shepard IDs
  -add shift ID
  -consider making a `State GoatState` Monad... 
  -deal with the undofirstsituation 
    -rename to mouseACtive?
    -just get rid of it and instead check if there is an associated local preview?)
-performance pass
  -https://medium.com/e-bot7-tech/improving-performance-of-your-haskell-code-with-profiteur-8d2e025b6779
-REFACTOR split goat mouse intput into 2 commands, one for layer and one for canvas
-BUG resizing unattached lines does not work
-BUG
  -now you get stuff like this, there's no arrow when there should be one, that's because you messed with determineSeparationForAttachment to not have the extra 1 offset
  -really there just a bunch of edge cases here that you need to deeal with based on arrow/now arrow and whether the attachment points are in 1 line or not etc :(

    ║            ╚╗
    ║             v
    ║╔OwlPFWor═══════════════╗
-maybe make styles references instead of stored per elt
-do label position adjustment when adding midpoints
-text zipper
  -you should just rewrite text zipper and add select support..
  -BUG wrapping when single word (when word wrapping wont fit anymore) exceeds max width does not seem to handle wide chars correctly (seems to count them as 4 instead of 2?)
  -cursor up/down should work with display lines
-right click menu support (send forward/backwards) (do this is tinytools-vty, make sure inputs get captured ug)
-opening file with hidden elements does not hide stuff..
-someway to diff 2 objects for debugging
  -you can use aeson diff I guess...
-BUG still getting ? at double back midpoints (the real issue is you have double back midpoints)
  -prob just ignore until you do lucid style lines?
  -LineDrawer.hs midpoint anchor rendering will double back on itself, you need to force the attach direction to change based on neighbor rather than use AL_ANY
-finish substract lbox (-- TODO crop away mleft/mright from mtop'/mbot')


::????? PRIORITY
-switch layers to use tree (you have a branch for this)
-allow new lines in line labels :O
-BUG foldgoatfn gets called 3 times for each event wtf 😭 (probably due to holdUniqDyns I guess)
    -you should fix cuz it makes debugging hard...
    -you got it down to 2 :O
-BUG there are still some EoL cursor bugs with unicode characters
-BUG some prelude.!! error somewher ;__;
-should be able to rename elements for you based on first entered text maybe (ugh)
-fix
  -- TODO this should be r' not a FIX ME why is stuff even working???
  -- TODO there is a bug in cartRotationReflection_apply/cartRotationReflection_invert_apply where we don't actually apply the rotation but somehow this only works with that bug... Maybe the rotations cancel out?
-BUG selecting severals items and moving takes forever :(
  -can't repro anymore? at least not  from opening a file, maybe it's due to a leak?
  -also selecting via folders and moving didn't seem to cause this slowdown
-charwidth needs to be passed in rather than rely on global
-consider using LineAnchorsForRender/sAutoLine_to_lineAnchorsForRenderList  for cache instead
-add mouse hover support (for when you do web port)
-FEATURE info/statusbar/output area (right side?)
-TESTS TO ADD
  -create box, turn to text box, add some text, turn to regular box
  -drag parent folder into a child folder and ensure it does not work
  -create folder with children, select folder, attempt to drag via children (doesn't work right now)
-figure out how to change folders into groups for auto-pathing group support
  -is it just a folder setting?
-FEATURE options menu
  -could you do style defaults in this menu too?
  -like ideally following the same model you did in Params.hs....
-FEATURE add anchor repositioning dragging
  -add anchor positioning var first
  -create interface for dragging anchors in line handler
  -maybe design way to directly attach at offset position?
    -line anchors for render could highlight the entire box and flash the center point?
      -you probably want options to disable this stuff
-insert vs overwrite option for freeform text
  -you need some kind of options object to go along side of _setPotatoDefaultParameters_sBoxType



DONE/IGNORE-GHA build and release
DONE/IGNORE-do linux and windoze build

DONE- --tutorial to open tutorial otherwise empty by defaultcd
IGNORE/FAIL/DONE-LHRESS_ChildSelected graphic broken during drag and just in general 
  -make a deep chain of folders, then in one of the folders have several children, selecting that folder will cause the folder just above it not to be  LHRESS_ChildSelected
DONE-BUG asserting `r = fmap (\(i, sall) -> (internal_getSAutoLineLabelPosition (larlist `debugBangBang` _sAutoLineLabel_index sall) sal sall, i, sall)) sortedlls`

DONE/IGNORE?-line labels still cropping on right side  
IGNORE-add render handler name property so you know what the render handler is from its renderhandleroutput
IGNORE-add a visual anchor for the box label so you know you can add one easily
DONE-add upper bounds to all packages
DONE-BUG `invalid = error "toggling of LHS_XXX_InheritTrue elements disallowed"`

  -the issue is we prevent locking/hiding if parent is locked/hidden but not if parents parent etc is
DONE-BUG textarea handler crashes
DONE/IGNORE-add box border toggle
IGONRE-TESTING check for leaks again
DONE-BUG after renaming folder, clicking on canvas pane does not finalize the folder rename action until you click back on the layers pane

      -can you tie this into graceful handling of bad mouse states?
  DONE-make new elts get created inside selected folder rather than above it?
DONE-you somehow hit assert `Just (False, _) -> assert (not (pIsHandlerActive next_handler')) $ (refreshedHandler,refreshedLayersHandler) where`
  -from playing around with line arrows clikcing back and forth...
DONE-move over to minimaple account?

DONE/IGNORE-pregenerate unicode and figure out how to distribute using nix?
IGNORE-Line presets sholud be for start/end
IGNORE-BUG you sometimes hit this assert, need repro
  -Just (False, _) -> assert (not (pIsHandlerActive next_handler')) $ (refreshedHandler,refreshedLayersHandler) where

DONE-BUG return key in layers during rename will act like "tab" taking you to params, don't do this
DONE-warning cleanup
DONE-hide stuff
  -moving an element into a hidden folder does not hide it right away (ignore this for release)
    -this is becaues it gets added to superowlchanges
  -moving a hidden folder (in folder hierarchy) shows it (maybe cuz it's selected ,but it does'nt look selected?? and also deselecitng doesn't hide it)
    -this is becaues it gets added to superowlchanges
DONE-layers improvements
  DONE-when dragging into a folder, the | should then L to the element being moved
  DONE-currently not possible to drag the last element in folder outside of that folder if there's something below it
    -the trick is if you drag the last element in a folder to the spot below it, you need exception case to move it outside of the folder rather than as the next sibling to itself since that doesn't do anything
  DONE-currently not possible to drag below a folder if the folder is thet last sibling :(
    -not sure if there's a way around this :(
  DONE-DO THIS you might want to consider doing the thing where dragging to the right side of a folder puts it underneath, otherwise it's always a SiblingPosition
  DONE-selecting multiple items in layers and click on on should select that one item, but right now it gose into rename mode
DONE/IGNORE-BUG translating lines should translate midpoints too
DONE-text box option that auto goes into edit text box
DONE-render testing utilities 
DONE-empty text zipper should return '' span with cursor 
  -without this, empty cells don't show the cursor...
    -NO this is not the issue :()
DONE-clicking on params then clikcing over to layers does not cause focus to go away on params??
DONE-fix return navigation in params (you disabled it because it was breaking return to rename in layers)
  -you can/should probably add focusID to paramswidgetfn NBD
DONE-hitting assert checkvalid = assert (pIsHandlerActive canvasHandler /= HAS_Active_Mouse && pIsHandlerActive layersHandler /= HAS_Active_Mouse)
  -repro is pan, resive canvas in params without confirming (pressing tab or cilkcing somewhere in params), and then click on canvas area
  -you can also repro by pan, resive canvas in params, and confirm by cilkcing within params
  -another repro is to pan ,then hit "new"
DONE-style input not support ' ' correctly
  DONE-preset style should have ' ' as default fill char, right now it's empty
  DONE-if you click on the style params section, it forces the fill char to be space and not empty
DONE-hitting assert  when go into text box, type "ee"+return and then click on layers... 
DONE-you have a perma broken tt file (see attached) 
  -rerpo is to pan and save, and open. initial render canvas doesn't account for pan so later tries to render out of bounds inside vty

DONE-BUG cursor not showing at very end of canvas size text entry boxes, also happens in filename widget and justall text boxes
  -displayLinesWithAlignment does not add trailingcursor I think
DONE-BUG remove `checkvalid = assert (pIsHandlerActive canvasHandler /= HAS_Active_Mouse && pIsHandlerActive layersHandler /= HAS_Active_Mouse)`
  -repro is change canvas size and click in canvas area to confirm
DONE-BUG figure out why you are hiting `in assert (_goatState_focusedArea goatState == GoatFocusedArea_Layers) $ goatState_afterAction  `
  -repro is to rename a folder, click canvas, click back to folder 
  DONE-also add a UT for this..
DONE-make screenshot
DONE-BUG resize window after panning is VERY BROKEN
  DONE-add a UT for this
DONE-hardcode the xterm text width file?
DONE-make a regular tutorial doc
DONE-remove potato references :(
DONE-get rid of text box tool 
  IGNORE-fix box converting to text box
    DONE-add a UT for this...

DONE-return key while renaming layers should confirm it
DONE- more style presets please (singl eline ascii box)
DONE-cursor dosen't show up at end of layers (probably sam eissu ewith the '' cursor tag from zippers)
DONE-when you do new file ,you don't los ethe file reference from previous session LOL <___< fuck
DONE-add --version command
DONE-go over nix pills
DONE-fix PanSpec...
DONE-enable/disable widechar/grapheme cluster configs
DONE-YOU HAVE 2 WIP CHANGES RIGHT NOW OOPS 
  DONE-BOX CONSTRAINTS
    -broken because the constrainDeltaLBox function is applied to post preview state
    -you tried to fix this by setting box size instead, but you still have the same problem
    -you can fix by tracking pre-preview state and passing that in as well, but is there a better way?
      -I guess you could track the previous transform operation OR mouse position and add that back?
  IGNORE-FOLDER DRAG BASED ON X POSITION (broken because you need to handale recursive depth or something like that I'm actually not sure...)
    -see branch layerdragbyposition

DONE-BUG inverting boxes is broken (anchors move wrong corners)
  -I thought you disallowed inverted boxes? You definitely did, why is this OK again?
DONE-BUG if you undo a folder move from outside to inside another folder, it breaks, I think it's because the depth for the item inside the folder being moved is not being set correctly
DONE/IGNORE-figure out what to do to generate default term width file
  -also improve instructions, maybe make term width file a option rather than it's own binary!
DONE-BUG you somehow hit `assert nochildrenifaddingfolder`
  -drag folder somewhere and then undo
DONE-properyl return Preview_Commit actions where appropriate
  -BoxHandler creation, move
  -LineHandler creation, endpoint/midpoint/label move
DONE-make the welcome pop up scrollable
DONE-delete CartLine
IGNORE-introduce "cancelHandler" function
  -why would I want to do this?
  -gets called from GoatWidget when some higher order operation cancels or replaces the handler
    -must distinguish between cases where a handler is replaces vs when a new one gets returned by previous handler
  -can this be somehow combined with reset handler?
  -exsiting ways ah andler can be canceled
    -mousedrag_cancel (actually dosen't cancel, jsut resets the handler so no)
    -you get lazy sometimes and just return no handler such that Goat regenerates the handler from selsection and this will now become a cancel
    -keyboard escape
    -click outside of handler capture area which causes goat to regenrate a new selection handler
    -pReseteHandler may clear the handler
      -is this what happens when a you delete an object in the layers?


:: Preview Operations Mini Refactor 8/2023
DONE-get rid of controllerswithid->llama->controllerswithid circular nonsense
  DONE-in particular, get rid of Llama->ControllersWithId, we work with Llama's directly now!
  DONE-remove PFCmd stuff from WSEevent
    -this is hard because of usage of lastState in OwlWorkspace. We need a notion of lastState which is state before any preview is applied (or better just the local preview)
      -may you can unapply the local preview to generate last state, requires assumption that local preview can always be unapplied which I'm not sure is true or not...
        -actually just carry around state before any previews applied? But will that break any assupmtions? Maybe we really just want only the local preview unapplied
      -or does this lastState stuff even matter anymore if you use set operations
        -I don't think it does, but for cerating new elts you need to call owlPFState_nextId to get the id, but we will have a state-independent uuid generation function now?
DONE-goat refactor warmup
  DONE-get rid of GoatCmdTempOutput
  DONE-do goatCmd endo refactor, separate routines for each GoatCmd
    IGNORE-after moving everything to endo style, you'll need to find a new home for 
      `goatState = goatState' { _goatState_unbrokenInput = "" }`
      -probably add some common routine to every endo fn I guess
  DONE-BUG selecting does not auto expand folders
  DONE-BUG hiding layers causes crash because broadphase isn't being updated
  DONE-split hoa_layers into 2 separate things
  DONE-add processHandlerOutput :: PotatoHandlerOutput -> GoatState -> GoatState
  DONE-refactor out goat update routines in foldGoatFn
    DONE-set selection
    DONE-set pan
    DONE-update layers state
    DONE-apply event
    DONE-render / render selection
    DONE-update selection
    DONE-set handler from selection
    DONE-refresh Handler
      -this is tricky because we this may cause the handler to send a cancel preview operation which would normally have us refreshing the handler again
      -I think you want to reset the handler sooner in the flow (before set handler from selection)
  IGNORE-refactor out layers handler in foldGoatFn
  DONE-switch HOA_DEPRECATED_PFEvent to HOA_Preview
    -remember to do Preview_Commit as needed 
      -or instead we do the thing where the next Preview_Start commits the last preview?
        -no I think you want explicit commits
        -actually I think you don't want explicit commits, or make it optional. It's kind of awkward to cancel in some places e.g. keyboard movement
          -we could cancel when they leave the handler which would require an additional cancel handler function and would not capture cases where user just went AFK with the handler after making some keyboard changes
  DONE-refactor PotatoHandlerOutput to be mutually exclusive
DONE-create preview list (I guess you can just put it in PFWorkspace for now...)
  -Map UserKey (Maybe LLama)
    -this isn't quite right, because the previews are applied/unapplied in order. so it should probably just be [(UserKey, Llama)]
  -question should we store local preview separately and always apply it last/first?
DONE-assert when starting a new handler that there is no local preview action
DONE-handler -> preview -> goat -> pfworkspace -> unapply old previews by that user -> create new state/preview list
IGNORE-pRefreshHandler needs to return an output action and the only possible output is HOA_Preview PreviewCancel (or HOA_Nothing for the layers handler)
  -actually maybe it's not unreasonable just to cancel the preview always
DONE-implement PO_CommitAndStart
IGNORE-do PO_Commit on mouse up in all the handlers
DONE-I think you need switching handlers to do a commit as not all handlers have a reliable point to commit
IGNORE-replace pIsHandlerActive with just checking if there is a live preview opeartion or not
  -no I think you need/want both, there are some handlers that are active but don't do Previews
  -maybe default implementation of pIsHandlerActive could check for a live preview? Can/should previews be associated with handlers for error checking purposes?
    -maybe give handlers an Id
IGNORE-I think you may want explicit onReplaceHandler operation. Not every handler wants to commit their changes when they get replaced
  -specifically, there's a convert to text box preview operation when you enter text mode on a non-text box, we want a preview to convert it to a text box, and if this handler gets replaced, we don't want to commit the change
  -perhaps you can just have a commitOnReplace :: Bool function, that's probably easiest


:: TODO 7/2023

DONE-BUG toggle expand/hide/lock in layers should not alter selection (right now it deselects)
DONE-tests
  DONE-endSetFocusedArea test, start renamin,g change focus, ensure rename happened
  DONE-auto expand folders after selection
  DONE-hide/lock layers and check selection works as expected
DONE-warning cleanup
DONE-figure out why scrolling in file explorer is hecka broken
  -I don't think there's anything wrong with code, scrolling freezes input for some reason in vty on mac terminal :|
IGNORE/DONE?-make sure it's not possible to open up a pop up while mouse dragging (or you will break mouse drag pane2 stuff again)
  -it's definitely possible to do that but nothing seemed to break???
  DONE-auto expand folder after dragging into it
  DONE-do proper folder position
DONE-update README.md with usage instructions
DONE-move over to minimaple account
DONE-cursor rendering is broke if there are multiple new lines
DONE-BUG can't enter multiple new lines into text box
  -seems to be a bug in TextZipper
DONE-BUG click on eol in text box is kind of broken in general[]
  -doesn't always take you to the end
  -sometimes takes you to begining of next line (it happened to me when you click the same place past EOL twice in a row)
    -this is probably because there is a bug with how you handle the cursor/selected character 
DONE-BUG cilcking on auto wrapped lines after the first one does not work
DONE-gotolineposition broken when word is wrapped to next line (still does it based on character level wrapping for some reason)
DONE-disable or fix circleci
DONE-BUG index out of bounds somwhere with wide chars (pretty sure it's in ttvty but may be in zipper)
DONE-add switch start/end button to line params?
DONE/FAIL-make tutorial file, I think you have everythingy ou need now!!!
DONE-finish line endpoint unit tests
DONE-get rid of textbox tools
DONEish-bxoes should be text boxes by default, remove the text tool
  -click selected non text box will convert it to text box and clear all text
    -it's alittle weird because you singel click text box right now to end text
  -toggling text box will behave as before (preserving text)
DONE-tutorial...
DONE-draggable anchors
  DONE-change this so it tracks box we were attached to at the beggining for the duration of the AutoLineEndPointHandler drag  such that you can detach and reattach
  DONE-you can now have lines coming from the same side of the box so you need to handle the both lines in same direction case
  DONE-BUG some of the anchors don't match with where the line gets drawn to
    -I think basically you need to rewrite a bunch of the linedrawer methods which assumed anchors started from the middle? ug?
    DONE-project ratio calculation seems to project to a point that's off by 1 sometimes
      -might be due to offset border nonsense?
  DONE-break ties use mpreval in projectAttach
DONE-flip arrow button
IGNORE-probbaly remove text ICU dependency :\
DONE-BUG
  -this is due to (hsep, vsep) = determineSeparationForAttachment (lbx1, (1,1,1,1)) (lbx2, (1,1,1,1))

DONE-attachment stuff
  DONE-use better function to determine if you clicked on lines (you can do this now)
    -this should have access to the RenderCache/OwlTree
  DONE-attachment handle rendering
    -just having line handler selected should not render attachment handles (only when dragging handle end)
    DONE-having Line tool selected should highlight attachment points so you can create a line and attach right away
      DONE-TODO I think you want to make it so selecting tool changes the handler.. You'll need to update each handler to handle empty (non selection) states though D:
  DONE-move no longer makes sense on attached lines, find a way to disable it
    -or don't disable it...
    -remove it from Box select handler selection?
  DONE-lines can't be attached on first drag
  DONE?-BUG drag off attachment logic is wrong for Line handler
    DONE-just do the controller refactor!! D:
IGNORE-BUG attached lines don't render when you drag in some directions
  -I think this is due to an update order, i.e. the AABB is computed from the old line's AABB rather than the new line's AABB (it needs to be both!)
  -NO this was also probbaly due to out of date cache or something idk wtf???
  -well it's magically fixed now W/E
DONE-Select box + attached lines
  DONE-kind of weird that fully attached lines don't move with select box... I guess partially attached lines do?
  DONE-selecting multiple fully attached lines should not allow moving?
  DONE-selecting fully attached line and something that can be moved.. I guess the box should draw around just the stuff that can be moved
DONE-after DELETING object line is attached to, line should prob reset its endpoint position to where it was attached
  -prob makes most sense to scan for all objects
    -this might have some weird edge cases in multi user mode but whatever?
  -prob better scan for all attached stuff in PFWorkspace then
  -was I suppose to put the attachment map inside of the workspace D:
DONE-BUG you can reset handler by pasting or selecting on layers and it doesn't reset the tool back to select
  -I guess you also need handler -> set tool?
DONE?-BUG line ends attach at wrong places (off by one)
  -this happens in even width one cases
DONE-select box boundary uses origin line endpoints rather than attached points
  -need to set box width to infinite
DONE-BUG attach lines sometimes don't render (this is a broadphase box-to-rerender issue probbably)
DONE-when overflowing in boxlabel it will go to next line when it should keep going to the right (and still be invisible)
DONE??-BUG manipulators sometimes don't respect screen pan
  -repro is pan and then select via layers and the selection will use the old pan setting
  -this does not happen if you pan and select via canvases and fixes the pan setting
DONE-BUG multiselect with text box in selection and then clicking on text box will cause it to try and go into text edit mode and crash becaues it expects only one text box to be there
  -you can either disable this or do a second collision to determine which text box you clicked on
DONE-BUG box styles are "contagious" if you multi drag a box, it's style will apply to everything in that selection group...
  -this happens because params is triggering (for both ssytle and linestyle) when you click and drag on canvas side
DONE-BUG keyboard hotkey to change tools visually changes tool-s but you are still in select mode...
DONE-backspace should delete too
DONE-after DELETING object line is attached to, line does not get rerendered
DONE-add a regenerateAttachmentMap and verifyAttachmentMap UT
  FIXED-it's crashing :(
FIXED?-BUG doing a box select just to the left/top of a box will select it when it shouldn't
DONE-when drag selecting, box should auto resize to +1 so you don't have invisible drag box
IGNORE-I think you need some kind of cache monad
DONE-need another area for tool options

DONE-BUG setting line ends style seems to be broken again
  -I think this might be because of params mouse focus issue again...
  -no it's because you aren't using line style in the new line render stuff doh
DONE-BUG clicking from changed text entry box in Params  to Canvas causes changes not to apply reset :(
  -this happens for 2 reasons
    -1 the params widget may get closed on if you change selection
    -2 unfocus event never happens because input does not get passed into left widget

  DONE-BUG, right now if you select via folders, do and operation, unselect, it will allow you to reselect locked/hidden stuff for some reason 😱
    -this must be happening because something is being set incorrectly inside of layerMetaMap??
  DONE-because folders allows selecting locked/hidden stuff, you need to remove this stuff before generating handler from selection
    DONE-you also need to remove locked/hidden stuff into selection that gets passed into handlers

  -improved renderer spec
    -kd tree in broadphase I guess
  -connections spec
    -there may be missing/invalid connections, that's ok, just figure out a way to handle them

DONE-7/2021 folder drag bugs
  DONE-can't reach last spot

  DONE-sibling computation puts you in wrong spot for some reason
  DONE-isundofriendly assert should only lump together stuff that has the same parent I think
  DONE-must deny selecting child of a selected object
    DONE-visually do shadow select to indicate this in layers so it's no confusing?
  DONE-add dots for dragging several layers so it's clear which folder you're going under
  DONE-do selection correction in GoatWidget rather than deny invalid selections
    -this is really sucky b/c if you have folder selected in layers then you can't select any of its children in main area
    -prob best way to fix is selecting parent includes all children in selection (locked and hidden stuff removed in main are aselection when we implement it)
      -when deselecting child, then this must deselect all selected parents recursively... hmm
  DONE-fix shift select parent case (must deselect selected children)
    -alternatively, you could do disjoint uninon with selected children.. whatever
  DONE-due to layers capturing input now, ctrl-z doesn't work after doing layer drag

  DONE-add Maybe to params widget so they don't get displayed if no such option exists
  DONE-fix tab widget recreation issue preventing you for tabbing accross style widget
    DONE-also need to reset cursor to start
  DONE-figure out how to do invis fill?
    -erase and hit escape or return 👍🏽
    -maybe just add an invis fill button
    -fill should be separate from rest of stuff in preset params

DONE/IGNORE-rethink keyboard input capture
  -params needs to capture keyboard input
  -params need to receiev events from glpyh selector
DONE/IGNORE-you probably want to build in input hierarchy
  -popup > menu > params etc > rest
  -make widget wrappers
  -ignore input when simulataneous with another event
  -some focus widgets??
  -find a place to put all these
DONE-render cursor position in text area (get cursor pos from displayLines)
DONE/IGNORE-single line text area
  -max width?
  -reset to start
  -colors
IGNORE-try vscode again :O https://github.com/haskell/haskell-language-server
DONE-try stacktrace omg
  $ ghc -O0 -rtsopts=all -prof -auto-all --make stacktrace.hs
  ./stacktrace +RTS -xc
DONE-add output to main to figure out how many ticks fire per event (and what frame # it's at)
DONE-do alignment offset in boxtext
DONE-click to focus on text handler should also pass in input so you can focus TZ cursor at spot where you clicked
  DONE-add a test for this
DONE-fix handles being rendered too late IDK how D:
IGNORE-why does loading file select stuff?
DONE-first character of left align text box is incorrect (seems to be space character instead of Nothing)
DONE-why does large canvas slow down stuff so much. Rendering shouldn't be that bad???
  -doesn't seem to be taking advantage of laziness either
  -seems to just be a profiling mode thing...
DONE-new vty layout stuff
  DONE-get rid of post build dependency
  DONE-(tile . fixed)/(tile . stretch) take regular VtyWidget
  DONE-make typedef for (,,,) thing
  DONE-document
  IGNORE-probably get rid of IsLayoutResult class
  DONE-finish LayoutDebugTree (rename)
DONE-change SuperStyle to Maybe PChar :scream:
DONE/IGNORE-decide what to do about layouts (mouse needs pane2)
  -think about doing docking windows or whatever
DONE-no border box support
  -I guess you can make border and text two separate toggles?
DONE-do popup fancy :O
DONE-finish params widget
  DONE-create set of Params modifying widget, something that ultimately does
    Dynamic t SuperOwlParliament -> m (Event t WSEvent)
  DONE-create something like
    layoutDump :: DMap ParamTypeTag (MinDimensions, VtyWidget t ???) -> VtyWidget (DMap ParamTypeTag ???)
  DONE-although tbh, you can just replace DMap with [] since every params widget returns the same type prob?
DONE/IGNORE-TextArea stuff
  -handle updating text zipper when the stext lbox gets updated
  -figure out how to handle funny case where space and newline characters get hidden if they happen right at the end of a wrap
    -you'll need to store a second piece of data alongside TZ to track this (i.e. raw string)
  -clear out pSelectionChanged comments
IGNORE-params
  DONE-prob a view only thing, add hookup for params in goat widget I guess
  -need common methods for reading style of multi-select stuff
  -is there a way to systemize different types of styles
    -SuperStyle
    -TextStyle
    IGNORE-LineStyle
      -make this part of SuperStyle
      -when displaying, show simplified version of it
    -BoxTitle
IGNORE-although maybe you'd be better off just disallowing these from being created (in creation/modify, just ignore if result is 0 size box)
DONE-mouse select should select 0 size elts
DONE-copy pasta translate a little by default?
  -or attempt to place in middle of canvas viewport prob better
DONE-get rid of broadphase state
DONE-generate vty char width table
DONE-see if unicode combining marks work after you generate the table
DONE-write a UT for negative area box text as this is causing a negative index issue somewhere with the text zipper probably
  -you prob want to short circuit if box is negative and just display nothing or whatever and stop updating TZ
DONE/IGNORE-go over box sizing semantics
  -it seems you may be off by one, (i.e. a 2x2 size box renders as a dot D:)
DONE-figure out why sbox doesn't render right in vty
DONE-toMouseManipulators broken
DONE-SEltLine drawer broken when arrow goes in wrong way (indexing into arrow heads wrong)
DONE-if you get an event while BoxText handler is open, it will break undoFirst stuff
  -you need to track when non-handler events come in...
    -you'll have to do this anyways for multi-user mode right?
    -maybe just remake the handler, or perhaps add a reset method to handler??
      -should reset method take SEltLabelChanges... it probably should D:
IGNORE-assert handler is inactive if it does not capture
DONE-box border offset/no offset stuff D:
DONE-box text renderer lol
DONE-box with border test D:
  -pretty sure there is a bug with this in BoxText
IGNORE-default don't fill boxes pls
DONE-right now if you click realease on a text box it will go straight into BoxText handler, only do this if it was already selected
DONE-get basic box working using existing text zipper
  DONE-add UTs (assume align left for now so they'll work when you add alignment)
DONE-add text functionality to SEltBox
DONE/IGNORE-custom serializers for SEltLabel
  DONE-prob just use Data.Binary
  IGNORE-thought you could do something more efficient to omit optional parameters
  IGNORE-save load test
DONE-connect handlers to vty
DONE-connect layers to vty
DONE-sort out input hierarchies in vty
  DONE-support popups
  DONE-layers/canvas separate mouse input
  DONE-keyboard goes to popups/params first, then to goat
  IGNORE-am I missing anything??
DONE-consider making REltId serialized (you'll need this to do connections)
  -remember to support copy pasta of connected elts
DONE/IGNORE-think through what additional data is needed to validate for undo/redo in multi user mode
DONE-rename master branch
DONE-resolve ControllerMeta REltId synchronization issue
DONE-copy pasta
  DONE-implement copy
  DONE-ctrl-v/s/z/etc sent via keyboard,
    -other kind of copy paste supported via KeyboardKey_Paste
    -we'll prob need to do something different for web version...
  DONE-copy pasta test
  IGNORE-I think the way it's handled right now (PFEventTag operations) is cor

-address the following TODO in substract_lBox
  -- TODO crop away mleft/mright from mtop'/mbot'

-address the following TODOs in Goat.hs
  1. -- TODO move into its own file
  data GoatState = GoatState {

  2. -- TODO instance GoatState HasOwlTree

  3. -- TODO rename to makeHandlerFromCanvasSelection

  4. (hard)
  -- TODO probably should have done "Endo GoatState" instead of "GoatCmd"
  -- TODO extract this method into another file
  -- TODO make State monad for this
  foldGoatFn :: GoatCmd -> GoatState -> GoatState
    - `Endo GoatState = GoatState -> GoatState`
    - this part of the code was written incorrectly, someday I want to split it up into several functions of type `Endo GoatState`, one for each GoatCmd
    - the unit tests are also written overly complicated. They rely on going through GoatWidget which is very unecessary and makes everything very complicated
    - so the most important part is to create a set of helper functions for unit testing this function directly

-address the following TODOs in OWl.hs
  1. -- TODO remove OwlMapping arg not needed
  locateLeftSiblingIdFromSiblingPosition :: OwlMapping -> Seq REltId -> SiblingPosition -> Maybe REltId

  2. OwlItem oinfo _ -> "elt: " <> (_owlInfo_name oinfo) -- TODO elt type
