TODO

memory usage for debug build (release build will be smaller by about 25%)

8K   ->    13.2M
128K ->    13.2M (expected worst case 16.6M)
128M ->   412.0M (expected worst case 2.3G)

Next few super long boring things to do::

• redo lsp threads such that no mutex needed for any rope stuff (done)

  • Also make the classes own the methods in lsp (done)
  • This will mean that parsers/renderers and keystrokes will not need to be individually locked (done)
  • And so it will be much faster (done)
  • At which point the main thread can also be blocked on user input or lsp responses and still be fast

• Add a superclass for editor called Window (which can be popup or tiled) (done)

• Add a recursive tiling class for windows (done)

• Handled by a single renderer that calls and renders each window (done)

• Make editor's functions into its own methods (classify it) (done)

  • While at it
    • Seperate system functions into a class that branches to support local / ssh / server modes.
    • Even lsp shouldnt be directly controlled because it can branch on local and server modes
      • check wolfSSH stuff for remote editing
      • Thick and thin mode
        • thin mode only shares screen diffing over the network - uses server settings / themes
        • thick only shared fileio and lsp data with local used for all else - uses local settings / themes
  • Redo hooks as a engine of its own.
  • And factorize renderer into its own class (and make it just return an array of the render without knowing teh x,y)
    • which is just managed by the renderer
  • which is reused by scrollers/ensurers too
  • this will then allow inlay hints to be possible
  • and also make VAI easier to implement

• Allow keybinds to be set in ruby

• then the fun part:

• Then allow ruby code to create and handle windows as extentions

• Then 3 inbuilt extentions being file manager, theme picker, tab selector

• Extentions can also be used as file openers (for like databases . diffing . images . audio etc)

• Local cache for state management (like undo history, cursor positions etc) (location can be set in config)

• make sure to write inbuilt extentions in cpp and not ruby

• also move default bar and clipboard back into cpp

• all lsp popups are no longer their own classes but instead windows (extention like) in popup mode

• skip opening binary files

• apply themeing in bg log bar lsp popus etc. to keep visual consistency

• searching/replace/Multi-Cursor (for just one lsp command for all) with pcre2 with regex (started by a slash) (disabled for large files)

• add links support in xterm (kitty like clickable links)

• And preprocess markdown in popups to be more like styled than just highlighted

• In the ruby libcrib populate toplevel binding and file and dir and rubybuild stuff and other similar constants

• in require_relative allow requiring without appending .rb if possible.

• Possibly in the future limit memory usage by parser for larger files

• Add a file picker suggestion while typing a path (including stuff like ~ and .. and $HOME etc)

• allow opening directory after filemanger is sorted out.

• commands to: change pwd load a rb file run a ruby command close a window etc.

• Add mgems for most common things and a ruby library to allow combining true ruby with mruby

• add command to set and use a file type at runtime

• color alpha in ini files

• Make warning before ctrl+q for saving

• LSP Bug: Check why fish-lsp is behaving so off with completions filtering.

• Line move: fix the move line functions to work without the calculations from folds as folds are removed.

• Editor Indentation Fix: - Main : merger indentation with the parser for more accurate results.

  • Ignore comments/strings from parser when auto-indenting.
  • Support for stuff like bash \ and math operators in other languages and comma and line starting with a dot (like in ruby) etc.

• Readme: Update readme to show ruby based config in detail.

• UI Refinement:

  • Finish autocomplete box style functions.

• Documentation UI: Capture Ctrl+h / Ctrl+l for scrolling documentation windows.

• Cap line_tree data limit for large files and just store about a thousand previous lines maybe? (lazily loaded)

• add :j<n> command to jump to line <n> in the current file

• and give warning for invalid commands

• and upon escape clear the current command

• allow multiline logging which captures the input entirely and y will copy the log and anything else will exit

• it will then collapse to being the first line from the log only

• allow flushing functions in ruby to tell c++ to refresh keybinds/themes etc.

• LSP: support snippets in completion properly check:: pull diagnostics for ruby-lsp lsp selection range - use to highlight start / end of range maybe? goto definiton signature help document symbol for the top bar maybe? (or workspace symbol) also setup workspaces Semantic highlighting Quick fixes Rename symbols

• Allow ruby to config lsp capabilities

• also try to fix why solargraph is the only one breaking on edits near emojis

• ruby-lsp also supports erb so thats a plus

• the ruby should have an api to be able to draw windows and add mappings to them

• Syntax highlighting

• ruby done!!

• finish bash then do all the directive-like ones like jsonc (first to help with theme files) / toml / yaml / ini / nginx

• then ch? then gdscript and python then erb then php

• then markdown / html

• then gitignore / gitattributes

• then fish then sql then css and [jt]sx? then lua (make with type annotations for lsp results)

• then haskell then gomod then go then rust

• Undo/Redo: Add support for undo/redo history.

• Auto brace selection: Add support for auto brace selection.

• Tree-sitter Indent: Attempt to allow Tree-sitter to handle indentation if possible.

UX

• Completion Filtering:

  • Stop filtering case-sensitive.
  • Normalize completion edits if local filtering is used.

• Basic Autocomplete: Keep a list of words in the current buffer for non-LSP fallback.

Major Features

• Search & Replace:

  • Add Search/Replace UI.
  • Support capture groups ($1, $2) or allow Perl regex directly.
  • Ensure virtual cursors are included in search positions.

• Multi-Cursor:

  • Add virtual cursor support (edits apply to all locations).
  • Add Alt+Click to set multiple cursors.
  • Allow search and place cursor at all matches.

• Block Selection:

  • Double-clicking a bracket selects the whole block and sets mode to WORD.

Visuals, UI & Extensions?

• Add color picker/palette (as a floating extention).

• Git: Add Git integration (status, diffs).

• AI/Snippets:

  • Add snippets support (LuaSnip/VSnip style).
  • Add Codeium/Copilot support (using VAI virtual text) as a test phase.

• SQL: Add SQL support (Viewer and Basic Editor) (as ruby extension).

• Prolly?: Add Splash Screen / Minigame.

Unimportant optimizations

• Performance:
  • Switch JSON parser to RapidJSON (or similar high-performance lib).
  • Decrease usage of std::string in UI, LSP, warnings etc.
  • Also for vectors into managed memory especially for completions/lsp-stuff.
