TODO

• Add a virtual text support (text that is rendered in the editor but not in the actual text)
  • Add a whitespace highlighter (nerd font). for spaces and tabs at start/end of line. as a test.
• 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/inlayHint & textDocument/inlineHint & textDocument/codeLens
    • 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 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 .scm files for all the supported languages. (2/14) Done.
• Add splash screen / minigame jumping.
• Add codeium/copilot support.
• Normalize / validate unicode on file open.
• 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 folding system and its relation to move_line_* functions. (Currently its a mess)
