TODO

• Fix indentation logic

• For "insertTextFormat": 2 in clangd and similar use only the last word in the signature when replacing

• Keep a list of words in the current buffer. (for auto completion) (maybe?)

• Add ecma to js and make tsx

• Add support for LSP & autocomplete / snippets.

  • First research
    • textDocument/documentHighlight - for highlighting stuff (probably tree-sitter is enough)
    • textDocument/selectionRange //
    • textDocument/completion - Obviously
    • textDocument/onTypeFormatting - seems promising for auto formatting (indentation etc)
    • textDocument/formatting & textDocument/rangeFormatting
    • textDocument/semanticTokens/* (probably tree-sitter is enough)
    • textDocument/linkedEditingRange - probably useful
    • textDocument/foldingRange - i will never use this for folding but it might be useful for other things.
    • textDocument/rename & textDocument/prepareRename - probably useful
    • And a lot more (just go through each for clangd and then expand to say solargraph).
  • Make a universal plug for lsp. So focus more on making a general purpose solid communication interface. Instead of something specific.
    • With a 4ish pass system. (more like each returned value from the lsp is used in 4 ways)
      1. One for stuff like jump to x position. or rename symbol x to y. (stuff that explicitly requires user request to do something)
         • Maybe even hover goes here
      2. One for stuff that only affects highlighting and styles . like symbol highlighting etc.
      3. One for Warnings/errors and inlay hints etc. (stuff that adds virtual text to the editor)
      4. One for fromatting and stuff like that. (stuff that edits the buffer text)

• Add codeium/copilot support for auto-completion (uses the VAI virtual text) as a test phase.

• Add a whitespace highlighter (nerd font). for spaces and tabs at start/end of line. not as virtual but instead at render time.

• Once renderer is proven to work well (i.e. redo this commit) merge experimental branch into main. commit 43f443e on experimental.

• Add snippets from wherever i get them. (like luasnip or vsnip)

• Add this thing where select at end of screen scrolls down. (and vice versa)

  • Can be acheived by updating main.cc to send drag events to the selected editor instead of just under cursor.
  • Then a drag event above or below will scroll the selected editor.

• Add support for virtual cursor where edits apply at all the places.

• Add alt + click to set multiple cursors.

• Add search / replace along with search / virtual cursors are searched pos.

• Add support for undo/redo.

• Add splash screen / minigame jumping.

• Normalize / validate unicode on file open. so use utf8 purely and fix other types of files

• Add git stuff.

• Add SQL support. (viewer and basic editor)

• Add color picker/palette for hex or other css colors.

• Fix bug where alt+up at eof adds extra line.

• Think about how i would keep fold states sensical if i added code prettying/formatting.

• Use tree-sitter to get the node path of the current node under cursor and add an indicator bar.

  • (possibly with a picker to jump to any node)

• Add the highlight of block edges when cursor is on a bracket (or in). (prolly from lsp)

• Add this thing where selection double click on a bracket selects whole block.

  • (only on the first time) and sets mode to WORD.

• Redo cpp/c/h scm file . also pretty much all of them do manually

• Try making lua-typed and man pages tree-sitter grammar.

• Redo folding system and its relation to move_line_* functions. (Currently its a mess)

• Make whole thing event driven and not clock driven.

• Fix in kutu.rb such that windows arent focused on hover . they are only when they are true windows and not just popups . also popus are focused even without hover when they open.
