-# Crib
+# Crib - a text editor
 
-A TUI IDE.
+### About
 
-# TODO
+Crib is a TUI based text editor built primaririly for personal use.<br>
+Crib has a vim-style editor modes system but navigation and shortcuts are very different.<br>
+It supports superfast incremental syntax highlighting.<br>
+And LSP for auto-completion, diagnostics, hover docs etc.<br>
+It aims to be complete general purpose IDE.<br>
+(It is still very much a work in progress so a lot of things may seem incomplete)<br>
+For now it is just a single file editor. I plan to add a multi-file support with file pickers and tabs soon.<br>
 
-- [ ] Add status bar & RUNNER mode
+## Installation
-- [ ] Maybe hide boxes in !`normal` mode
-- [ ] Fix indentation logic
-- [ ] Fix bug where closing immediately while lsp is loading hangs and then segfaults.
-- [ ] 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.
-    - Allow using perl directly for replace maybe? and others with my dfa?
-    - or add searcher that supports $1 $2 etc. (capture groups)
-- [ ] 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.
+Binary can be installed with the following command:
+
+```bash
+curl https://syedm.dev/crib | sh
+```
+
+It requires `libruby-3.2.so` or `libruby.so.3.4` to be installed in the system.<br>
+It also requires `libmagic` to be installed (most systems have it preinstalled).<br>
+Currently only for Linux.<br>
+*Tested with arch linux and ubuntu*<br>
+
+## Building
+
+### Get started
+
+Make sure the repo is cloned with submodules to get `libgrapheme`.
+
+```bash
+git clone --recurse-submodules https://git.syedm.dev/SyedM/crib.git
+```
+
+### Dependencies
+
+#### System-wide libraries
+
+Make sure you have the following dependencies installed (apart from the standard C++ libraries):
+
+* **[nlohmann/json](https://github.com/nlohmann/json)**
+  Install it via your package manager. Once installed, the header should be available as:
+  ```cpp
+  #include <nlohmann/json.hpp>
+  ```
+
+* **[PCRE2](https://github.com/PCRE2Project/pcre2)**
+  Install the library to use its headers:
+  ```cpp
+  #include <pcre2.h>
+  ```
+
+* **libmagic**
+  Install it so that you can include it in your code (most *nix systems have it installed):
+  ```cpp
+  #include <magic.h>
+  ```
+
+It also uses `xclip` at runtime for copying/pasting *(TODO: make it os portable)*.
+And any modern terminal should work fine - preferably `kitty` or `wezterm`.<br>
+
+#### `./libs` folder
+
+Some other dependancies are added as submodules or copied.<br>
+   - `unicode_width` is compiled by the makefile so nothing to do there.<br>
+   - `libgrapheme` needs to be compiled using `make` in it's folder.<br>
+   - ``
+
+#### LSPs
+
+Lsp's are defined in the `libcrib.rb` file and you can use your `config/main.rb` file to add more.<br>
+
+The following lsp's are added by default and can be installed anywhere in your `$PATH`<br>
+
+* [clangd](https://clangd.llvm.org/)
+* [ruby-lsp](https://shopify.github.io/ruby-lsp/)

+
+> As it is still in development, some of these may not work as expected or that well.<br>
+> It should work even if the lsp is not installed but lsp features will not work.<br>

+`clang++` should work fine but `c++23+` is required.<br>
+Can remove `ccache` if you want from the makefile.<br>
+
+#### Compliling
+
+```bash
+make release
+```
+
+### Running
+
+Preferably add the `bin` folder to PATH or move `bin/crib` to somewhere in PATH.<br>
+For some LSP's to work properly `crib` needs to be run from the root folder of the project. *To be fixed*<br>
+then do -<br>
+
+```bash
+crib ./filename.ext
+```
+
+*If `filename.ext` does not exist, it will be created*<br>
+
+## Keybindings
+
+TODO: add keybind information on how to set in `config/main.rb`
+      and default / unchangeable keybinds
+
+## Features Implemented
+
+#### Core workflow:
+- NORMAL / INSERT / SELECT / RUNNER / JUMPER modes
+- full mouse support for scrolling and multi-click word/line selection.
+    - Double click to select word
+    - Triple click to select line
+
+#### Core editing tools:
+- indent/dedent
+- move lines up/down
+- folding on a selected range
+- yank/cut/paste via system clipboard
+- per-language smart auto-indent on new line insert
+- bracket/quote auto-pairing
+- hooks jumping (bookmarking)
+- color hex code highlighting
+- current line highlighting
+- all instances of current word under cursor highlighting
+
+#### syntax highlighting and filetype detection (using extention or libmagic) for:
+- ruby
+<!-- TODO: -->
+<!-- - bash -->
+<!-- - c/cpp (and headers) -->
+<!-- - css -->
+<!-- - fish -->
+<!-- - go/gomod -->
+<!-- - haskell -->
+<!-- - html/erb -->

+<!-- - man pages -->
+<!-- - diff/patch -->
+<!-- - gitattributes/gitignore -->
+<!-- - tree-sitter queries -->
+<!-- - regex -->
+<!-- - ini -->
+
+#### LSP-powered features:
+- diagnostics
+- autocompletion
+- hover docs
+- formatting support
+    - Full file formatting on save
+    - Ontype formatting when inserting special characters defined by the language server
+    - *(few lsp's actually support this - try to configure a few more which can but need configuration and for others need to add support for external formatters)*
+- A list of some lsp's can be found [here](#lsps).
+- Any lsp can be added to the `config/main.rb` file.
+- Though not all might work well. Open an issue if you find a lsp that doesn't work well.
+
+**A lot lot more to come**

+# TODO
+
+##### BTW Check each lsp with each of the features implemented
+
+* Static link pcre2-8 and libmagic and add precompiled libmagic magic database for better file detection
+* [ ] **LSP Bug:** Check why `fish-lsp` is behaving so off with completions filtering.
+* [ ] **Critical Crash:** Fix bug where closing immediately while LSP is still loading hangs and then segfaults (especially on slow ones like fish-lsp where quick edits and exit can hang).
+* [ ] **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.
+    * [ ] Fix bug where enter at start of line with ending type crashes
+    * [ ] Keep cache of language maps in engine to reduce lookup time.
+    * [ ] In indents add function to support tab which indents if before any content and inserts a pure \t otherwise.
+    * [ ] And backspace which undents if before any content.
+    * [ ] Add block indentation support.
+    * [ ] Ignore comments/strings from parser when auto-indenting.
+    * [ ] These will dedent when the block immediately after them is dedented
+    * [ ] Dont dedent if ending is valid starting is invalid but also empty
+    * [ ] Just leave asis if starting is empty
+* [ ] **Readme:** Update readme to show ruby based config.
+* [ ] **UI Refinement:**
+    * [ ] Allow completion list to be scrolled; show only `x` max items.
+    * [ ] Finish autocomplete box style functions.
+* [ ] **Documentation UI:** Capture `Ctrl+h` / `Ctrl+l` for scrolling documentation windows.
+* [ ] Redo hooks as a struct.
+* [ ] breakdown the render function into smaller functions.
+
+* Try to make all functions better now that folds have been purged
+* Cleanup syntax and renderer files
+
+* Add a thing called view which is a rect with speacial type editor . but otherwise a ruby or c++ view
+* can be used for stuff like file manager/git manager/theme picker.
+* allow flushing functions in ruby to tell c++ to refresh keybinds/themes etc.
+* allow keybinds to be set in ruby
+
+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
+
+probably remove solargraph support and use ruby-lsp (or sorbet?) instead because it is a pain for utf stuff
+ruby-lsp also supports erb so thats a plus
+
+move lsp configs to json and also allow configs for windows-style vs unix-style line endings and utf-8 vs utf-16
+
+* the ruby should have an api to be able to draw windows and add mappings to them
+
+* finish bash then do all the directive-like ones like jsonc (first to help with theme files) / toml / yaml / ini / nginx
+* then markdown / html
+* then gitignore / gitattributes
+* then fish then sql then css and [jt]sx? then python then lua (make with type annotations for lsp results)
+* then [ch](++)? then gdscript then erb then php
+* 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.
+
+* [ ] **Scrolling:** Add logic where selecting at the end of the screen scrolls down (and vice versa).
+    * *Implementation:* Update `main.cc` to send drag events to the selected editor even if coordinates are out of bounds.
+
+
+### UX
+
+* [ ] **Editor word highlighter:** Do not recompute word under cursor if not changed.
+
+* [ ] **Completion Filtering:**
+    * [ ] Stop filtering case-sensitive.
+    * [ ] Normalize completion edits if local filtering is used.
+
+* [ ] **LSP Features:**
+    * [ ] Add LSP jumping support (Go to Definition, Hover).
+    * [ ] Add LSP rename support.
+    * [ ] Handle snippets properly in autocomplete: use only the last word in signature when replacing and set cursor to the first one.
+
+* [ ] **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 (first time only) and sets mode to `WORD`.
+
+
+### Visuals, UI & Extensions?
+
+* [ ] **Status Bar:** Complete status bar and command runner.
+
+* [ ] Add color picker/palette.
+
+* [ ] **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).
+* [ ] **Prolly?:** Add Splash Screen / Minigame.
+
+
+### Optimizations & Fluff
+
+* [ ] **Performance:**
+    * [ ] Switch JSON parser to `RapidJSON` (or similar high-performance lib).
+    * [ ] Decrease usage of `std::string` in UI, LSP, and warnings.
+    * [ ] Also for vectors into managed memory especially for completions/lsp-stuff.

+ * @param[in]      events  Event(s) to listen to.
+ * @param[in]      func    A callback function.
+ * @param[in,out]  data    Void  pointer that  will be  passed to  the callback
+ *                         function.
+ *
+ * When the callback function is called, it will be passed 2 parameters:
+ *   1. `VALUE  tpval` -  the TracePoint  object from which  trace args  can be
+ *      extracted.
+ *   1. `void  *data` -  A void  pointer which  helps to  share scope  with the
+ *      callback function.
+ *
+ * It is important to note that you cannot register callbacks for normal events
+ * and internal events simultaneously because  they are different purpose.  You
+ * can use  any Ruby APIs  (calling methods and so  on) on normal  event hooks.
+ * However, in  internal events,  you can  not use any  Ruby APIs  (even object
+ * creations).   This is  why we  can't specify  internal events  by TracePoint
+ * directly.  Limitations are MRI version specific.
+ *
+ * Example:
+ *
+ * ```CXX
+ * rb_tracepoint_new(
+ *     Qnil,
+ *     RUBY_INTERNAL_EVENT_NEWOBJ | RUBY_INTERNAL_EVENT_FREEOBJ,
+ *     obj_event_i,
+ *     data);
+ * ```
+ *
+ * In this  example, a callback  function `obj_event_i` will be  registered for
+ * internal           events          #RUBY_INTERNAL_EVENT_NEWOBJ           and
+ * #RUBY_INTERNAL_EVENT_FREEOBJ.

+ *
+ * For instance ::rb_define_method  takes a pointer to  #ANYARGS -ed functions,
+ * which in  fact varies 18  different prototypes.   We still need  to preserve

+ * those complex macro overlays defined in  this header file, use of a function
+ * pointer gets checked against the corresponding arity argument.
+ *
+ * ### Q&A ###
+ *
+ * - Q: Where did the magic number "18" came from in the description above?
+ *
+ * - A: Count the case branch of `vm_method.c:call_cfunc_invoker_func()`.  Note
+ *      also that the 18  branches has lasted for at least  25 years.  See also
+ *      commit 200e0ee2fd3c1c006c528874a88f684447215524.
+ *
+ * - Q: What is this `__weakref__` thing?
+ *
+ * - A: That is a kind of function overloading mechanism that GCC provides.  In
+ *      this   case  for   instance  `rb_define_method_00`   is  an   alias  of
+ *      ::rb_define_method, with a strong type.
+ *
+ * - Q: What is this `__transparent_union__` thing?
+ *
+ *   A: That  is  another  kind  of function  overloading  mechanism  that  GCC
+ *      provides.   In this  case  the attributed  function  pointer is  either
+ *      `VALUE(*)(int,VALUE*,VALUE)` or `VALUE(*)(int,const VALUE*,VALUE)`.
+ *
+ *      This is better than `void*` or #ANYARGS because we can reject all other
+ *      possibilities than the two.
+ *
+ * - Q: What does this #rb_define_method macro mean?
+ *
+ * - A: It  selects  appropriate  alias  of  the  ::rb_define_method  function,
+ *      depending on the last (arity) argument.
+ *
+ * - Q: Why the special case for ::rb_f_notimplement ?
+ *
+ * - A: Function   pointer  to   ::rb_f_notimplement   is   special  cased   in
+ *      `vm_method.c:rb_add_method_cfunc()`.   That should  be  handled by  the
+ *      `__builtin_choose_expr`   chain  inside   of  #rb_define_method   macro
+ *      expansion.      In    order     to    do     so,    comparison     like
+ *      `(func == rb_f_notimplement)`        is        inappropriate        for
+ *      `__builtin_choose_expr`'s  expression  (which  must be  a  compile-time
+ *      integer constant  but the address  of ::rb_f_notimplement is  not fixed
+ *      until      the      linker).        Instead      we      are      using
+ *      `__builtin_types_compatible_p`, and in doing  so we need to distinguish
+ *      ::rb_f_notimplement from others, by type.
