-# te, a text editor
+# te
 
-![preview](preview.jpg)
+A from-scratch text editor that aims to stay fast, hackable, and practical for day-to-day coding.
 
-In order to build on windows you need to call build.bat from
-the x64 Native Command Tools prompt that ships with Visual Studio.
+![te preview](preview.jpg)
 
-For Linux you will need clang, SDL3 and libbacktrace libraries to be installed and
-available on your system. Just call build.sh when these are available.
+## What this project is
+
+`te` is a native desktop editor written as a single C++ executable (SDL3 + OpenGL + custom editor core).
+It is built around a straightforward single-threaded architecture, with coroutines used for asynchronous workflows (searching, UI flows, process jobs) so behavior stays easy to reason about and debug.
+
+The codebase includes its own:
+
+- text buffer + undo/redo engine
+- window/view layout system
+- command system + keybinding parser
+- fuzzy selection UI
+- process execution and output streaming
+- built-in font fallback (baked into the binary)
+
+## Highlights
+
+- VS Code-style keybindings and command palette (`Ctrl+Shift+P`)
+- Multi-cursor editing (keyboard and mouse workflows)
+- Fuzzy-open patterns for commands, files, and open buffers
+- Project-wide search (`Ctrl+Shift+F`) and replace-all workflow
+- Shell integration directly from editor input:
+  - `:Command` to run editor commands
+  - `:Set ...` to configure options and keybindings
+  - `!cmd` / `!!cmd` to execute shell commands
+  - `py:...` to execute Python snippets via discovered Python interpreter
+- Build panel integration (`Ctrl+B`, `Alt+B`, etc.) with configurable build commands
+- Config-driven behavior (font, colors, project commands, keymaps, paths)
+
+## Build
+
+### Linux
+
+Requirements:
+
+- `clang`
+- `cmake`
+- `libbacktrace`
+- SDL3 (the build script can clone and install SDL when missing)
+
+Build commands:
+
+```bash
+./build.sh           # debug build (default)
+./build.sh release   # optimized build
+./build.sh slow      # extra asserts/instrumentation path
+```
+
+Run:
+
+```bash
+./build/te
+./build/te path/to/file.cpp
+```
+
+### Windows
+
+Use the **x64 Native Tools Command Prompt for Visual Studio**.
+
+Requirements:
+
+- Visual Studio C++ toolchain (`cl`, `msbuild`)
+- `cmake`
+
+Build commands:
+
+```bat
+build.bat
+build.bat release
+build.bat slow
+```
+
+Run:
+
+```bat
+build\te.exe
+build\te.exe path\to\file.cpp
+```
+
+## First steps in the editor
+
+- `Ctrl+N`: new buffer
+- `Ctrl+O`: open current file's folder / directory navigation view
+- `Ctrl+P`: fuzzy list of open buffers
+- `Ctrl+Shift+P`: all commands
+- `Ctrl+Q` or `F12`: open thing under caret (path / link / command)
+- `Ctrl+F`, `F3`, `Shift+F3`: in-buffer search flow
+- `Ctrl+Shift+F`: interactive search across open project buffers
+- `Alt+Shift+Up/Down`: add cursors vertically
+- `Ctrl+B`: run Build1 command (configurable)
+
+## Configuration
+
+On startup, `te` loads a config file from SDL's app preference directory (`config.te`).
+You can also pass additional `.te` files as CLI arguments.
+
+Useful examples:
+
+```text
+:Set FontSize 16
+:Set PathToFont '/path/to/font.ttf'
+:Set Build1OnUnix 'sh build.sh release'
+:Set Build1OnWindows 'build.bat release'
+:Set TextColor ff202020
+:Set BackgroundColor fffdf6e3
+```
+
+## Notes on architecture
+
+- Single-threaded main loop (event/update/render)
+- Coroutines for async editor tasks instead of multi-threaded complexity
+- "Plugin" modules are integrated in the source tree and compiled in
+- Focus on predictable behavior and low-latency interaction

-! What precise workflow do I need for me to be viable to use this?
-! From a user (novice) point of view, how does it look like?
-
-- Buffer edit history separate from caret history (tagging history blocks with carets???)
-- We need regex for: [FormatCode matching, IsCode matching,
-- Macros
-- Window position: vscode opens in fullscreen and then remembers what position it was close in (could be a config option)
-- On Linux: Try to implement is_debugger_present()
-- Maybe IPC for te.exe when it's already open and file arguments are passed it should perhaps open a buffer in current window??
-- Add <<File>> <<ProjectDirectory>> template strings to Open (Then remove SEtWorkdirhere)
-- :Set Filename to name current buffer ??? :O and others like that!!
-- Make a fuzzy command !> grep and fuzzy over it??? (doesn't seem very useful for grep)
-- Make the equivalent of SearchOpenBuffers but for cmds like !@git grep -n "@>"
-- Add Bool variable
-- Guide on the first page for new users with links to configs, tutorials
-
-Debug session:
-- Report errorf - use coroutine dialogs
-    - Replace in render layer also
-- BlockAllocator something is not working there which only showed after executing OpenCode on many files
-- Some bad allocating happening in Clipboard for sure OR MAYBE BLOCK ALLOCATOR ACTION
-
-New UI Session
-- Uneditable buffers ?
-- Maybe marked allocations??? So that we can associate allocations with a buffer or view and then dealloc all at the same time
-
-- Open with seek string (open at pattern) filename:32 filename:/^Window$/
-- Show what process/coroutines are running and allow to kill (active process buffer?)
-- Database idea: use special buffers to store information
-    - Editing the buffer doesn't seem to be the slow part rather, accessing the data and putting it into the buffer (potentially hitting many different memory locations) I have a crazy idea to use buffers in order to store the names in a serialized format
-    - non editable buffers (raw ops ok, non-raw no op)
-    - DBBuffer
-
-- Try to add Tracking Allocator and rewrite the app, free all memory at the end of the app and check all is well
-
-FEATURE Some decl/function indexing in fuzzy format
-FEATURE dump text editor state to file, restore state
-- word complete
-- escapeing multiple cursor after ctrl + d should put the cursor where it was (probably will need to swap secondary and primary cursor for new cursor
-- draw indentation levels like in sublime (those lines) - we render chars one by one so seems relatively easy to figure out if whitespace belongs to beginning of line (make sure to add max value like 40 because of big files)
-- code sections, visual demarkation if beginning of line has a very specific text + goto next / goto prev section hotkey!
-- combine glyph and selection rendering
-
-- Test stdin writing code
-- Implement shell interaction (the valid cmd lines should start with '>' or '$', user can add more lines like this to expand the command size maybe?, if we have a case where we have a line with '>' but the last line doesn't have (just a space) then it should execute?)
-- drop text into window
-- I think the way sublime text and we display line highlights is confusing with multiple cursors (line highlight can be confused with selection)
-- make the editor replayable, store events and then replay, be careful about globals
-- maybe open should return multiple options if there are many more? (like in sublime if many symbols you get a window and you choose and it automatically jumps you to the symbol in the background)
-- I want a way to assign flags to buffers/views/windows from user perspective so that console window concept can be created from user space
-- font cache and on demand unicode loads
-- color parens, braces
-- gap buffer
-- optimize rendering - command buffer, and vertice buffer instead of vertice buffer with scissor

-WORD COMPLETE
-1. Tokenize the file (or maybe couple last viewed files)
-2. Match the tokens (identifiers) with prefix string and produce a list
-3. Remove duplicates
-4. Sort by proximity to cursor
-
-We save the iterator, it's enough for it to be global with unique for it arena
-If prefix ask is the same - reuse the iterator go to next word, if there are none go to next buffer ...
-    else - dump old, create new

+## Basics
+- [ ] Ctrl+Shift+ArrowDown at the end of buffer, doesn't capture characters on last line without new line, same at the top
+- [ ] When inserting parenthesis and selection is there, put the parens on both sides?
+- [ ] I noticed WordComplete getting busted after using editor for a while and returning cutdown words but not sure how to repro ...
+- [ ] Rewrite WordComplete to use CoroutineCreate, maybe try reducing globals to just the coroutine itself
+- [ ] WorkComplete, Bounded search, after a while it becomes problematic with many buffers
+
+## Monaco like design for familiarity
+- [ ] ctrl-tab - switch file lister with instant hold release semantics?
+- [ ] SearchAndReplace how to do better?
+- [ ] ctrl-t find workspace symbols? how can we do it?
+- [ ] Snippet design?
+
+## Refactor
+- [ ] Make a platform layer and separate SDL stuff out
+- [ ] Report a regression in SDL in newer versions that make it so that events are doubled when unpressing the held button
+- [ ] Remove -lbacktrace and add my backtrace library thing
+- [ ] Refactor build.sh to accept commands and remove build_web.sh
+- [ ] GetWindowZOrder to IterateWindowsInZOrder
+- [ ] Investigate reworking history API, tagging modification blocks with carets?
+- [ ] How to enable framerate to be unlimited and not break scrolling?
+- [ ] When 2 views of same buffer are open, the view with caret below the caret which modifies the view - starts moving and getting messed up
+- [ ] The lexing / parsing code for config / bindings appears sloppy would be nice to clean it up but I don't have any ideas
+- [ ] Redesign `:QueryFile`
+
+## Features
+- [ ] KillProcess in console !!! - should also kill all the children ...........
+- [ ] BeginLog and EndLog, show all logs in the UI thing at the end
+- [ ] Fuzzy search over executed command ouput
+- [ ] Command window but for executing commands without special fuzzy stuff?
+- [ ] Implement Regex and jumps using regex so as to allow for using ctags
+- [ ] Add UndoKinds (SnapshotUndo, DiffUndo), I want to enable history in fuzzy search buffers without a huge memory cost
+- [ ] General parser / data description thing, rewrite other parsers using this, rewrite env handling
+- [ ] DirNav, update lister when files change on disk
+- [ ] Investigate ways to bind "open" commands to keys from config
+- [ ] Ability to access and set clipboard as well as affect selection in the open scripts
+- [ ] Syntax for executing commands from root of project, or maybe commands should be executed from root of the CurrentDirectory
+
+## Test
+- [ ] Test BlockArena correctnsess - random allocations, writes and undos, try to crash
+
+## Low
+- [ ] Shell / terminal buffer plugin (keep the shell alive and talk with it)
+- [ ] Fix somehow OpenCode hanging the editor on big files
+
+-----------------------------------------------------------------------
+
+## :QueryFile problems
+- User doesn't see that he in a special mode
+- Coroutine is boundless here and the boundries of the mode are too lossely defined, it makes it strange when you learn that you are still in this mode
+- How do we kill all the views/buffers we entered? Do we care?
