## Example Commits
### Feature Addition
```
feat: add Windows MSVC build support
- Fix CMake parser discovery for Windows drive letter paths
- Add platform-specific curses header includes
- Implement Windows-compatible setenv wrapper
- Force static runtime linking across all libraries
Tested on Windows 10 with MSVC 2019 and vcpkg static libraries.
Fixes #42
```
### Bug Fix
```
fix: resolve cursor positioning in PDCurses
Update renderer to use PDCurses-specific refresh sequences.
Prevents cursor from jumping during scroll operations on Windows.
Fixes #123
```
### Refactoring
```
refactor: simplify parser auto-discovery logic
Replace colon-separated string parsing with CMake lists to avoid
issues with Windows drive letters (C:, D:, etc).
No functional changes.
```
### Documentation
```
docs: add comprehensive build instructions
Create BUILD.md with platform-specific setup guides for Linux,
macOS, and Windows. Include troubleshooting section and vcpkg
integration details.
```

# Inheritance model for ecma-based languages
Ecma-based languages share many traits. Because of this we want to share as many queries as possible while avoiding nested inheritance that can make query behaviour unpredictable due to unexpected precedence.
To achieve that, there are "public" and "private" versions for javascript, jsx, and typescript query files, that share the same name, but the "private" version name starts with an underscore (with the exception of ecma, that already exists as a sort of base "private" language). This allows the "private" versions to host the specific queries of the language excluding any `; inherits` statement, in order to make them safe to be inherited by the "public" version of the same language and other languages as well. The tsx language doesn't have a "private" version given that currently it doesn't need to be inherited by other languages.
| Language | Inherits from |
| ---------- | ----------------------- |
| javascript | _javascript, ecma |
| jsx | _jsx, _javascript, ecma |
| typescript | _typescript, ecma |
| tsx | _jsx, _typescript, ecma |
If you intend to add queries to any of the ecma-based languages above, make sure you add them to the correct private language they belong to, so that other languages down the line can benefit from them.
```

[![pypi][pypi]](https://pypi.org/project/tree-sitter-markdown/)
A Markdown parser for [tree-sitter].
The parser is designed to read markdown according to the [CommonMark Spec],
but some extensions to the spec from different sources such as [Github flavored
markdown] are also included. These can be toggled on or off at compile time.
For specifics see [Extensions](#extensions)
## Goals
Even though this parser has existed for some while and obvious issues are
mostly solved, there are still lots of inaccuracies in the output. These stem
from restricting a complex format such as markdown to the quite restricting
tree-sitter parsing rules.
As such it is not recommended to use this parser where correctness is
important. The main goal for this parser is to provide syntactical information
for syntax highlighting in parsers such as [neovim] and [helix].
## Contributing
All contributions are welcome. For details refer to [CONTRIBUTING.md].
## Extensions
Extensions can be enabled at compile time through environment variables. Some
of them are on by default, these can be disabled with the environment variable
`NO_DEFAULT_EXTENSIONS`.

## Usage in Editors
For guides on how to use this parser in a specific editor, refer to that
editor's specific documentation, e.g.
* [neovim](https://github.com/nvim-treesitter/nvim-treesitter)
* [helix](https://docs.helix-editor.com/guides/adding_languages.html)
## Standalone usage
To use the two grammars, first parse the document with the block
grammar. Then perform a second parse with the inline grammar using
`ts_parser_set_included_ranges` to specify which parts are inline content.
These parts are marked as `inline` nodes. Children of those inline nodes should
be excluded from these ranges. For an example implementation see `lib.rs` in
the `bindings` folder.
### Usage with WASM
Unfortunately using this parser with WASM/web-tree-sitter does not work out of the box at the moment. This is because the parser uses some C functions that are not exported by tree-sitter by default. To fix this you can statically link the parser to tree-sitter. See also https://github.com/tree-sitter/tree-sitter/issues/949, https://github.com/MDeiml/tree-sitter-markdown/issues/126, and https://github.com/MDeiml/tree-sitter-markdown/issues/93

# Contributing
All contributions are welcome. Specifically, if you found a bug or have a
suggestion for a new feature or markdown extension, you can always open an
[issue] or [pull request].
## Issues
If you open an issue please give a short description of your bug or feature
along with a code example. If there is a relevant spec like the [CommonMark
Spec][commonmark] or the [GitHub Flavored Markdown Spec][gfm] please link it in
the issue.
Any feature suggestions are welcome. The grammar should by default only support
very common syntax, but any extension can be implemented behind a compile time
flag. (See below)
Some bug reports belong in other repositories if they only concern the
implementation of the grammar in a specific context like `nvim-treesitter`, but
you can always open an issue here and I will point you in the right direction.
## Code Overview
Please refer to the [tree-sitter spec] for more details on how to write a tree-
sitter grammar.
This parse is split into two grammars. One for block structure, which can be
found in the `tree-sitter-markdown` folder, and one for inline structure, which
can be found in the `tree-sitter-markdown-inline` folder. Components that are
parts of either grammar can be found in the `common` folder.
For either of the grammar the most important files are the `grammar.js` which
defines most nodes and the `src/scanner.c` which defines nodes that cannot
be parsed with normal tree-sitter rules. All other files in the `src` subfolder
are auto-generated by running `tree-sitter generate`. (You need to install the
[tree-sitter cli tool][tree-sitter-cli] and [Node.js][nodejs] first.)
Some syntactical components can be enabled or disabled by environment variables
at compile time. The logic for this can be found in the `common/grammar.js`
file.
Tests are located in the `test/corpus` subfolder:
* `spec.txt` is taken from the examples in the [GFM spec][gfm].
* `failing.txt` are those examples from the spec that do not pass yet.
* `issues.txt` are test cases covering solved issues.
* `extension_<>.txt` are covering specific extensions. Some of these are also
taken from the GFM spec.
## Pull Requests
I will happily accept any pull requests.
Before submitting any code please check the following:
* You ran `tree-sitter generate` in the `tree-sitter-markdown` or
`tree-sitter-markdown-inline` directories respectively after modifying any
`grammar.js` file.
* When running `tree-sitter test` only the cases defined in `failing.txt` or
`extension_<>.txt` for not activated extensions fail for **both** grammars.
* If you implemented new behavior please add tests. (In most cases these belong
in a `extension_<>.txt`.)
* You deleted any auto-generated bindings and files for debugging purposes
like `log.html`
## Tests
To run the tests, first install the development dependencies (see above), then
execute:
```sh
ALL_EXTENSIONS=1 node scripts/build.js
node scripts/test.js
```

# Quick Build Guide
**TL;DR:** Get up and running fast.
## Linux
```bash
# Install deps
sudo apt install build-essential cmake libncurses5-dev libyaml-cpp-dev
# Build
git clone --recursive https://github.com/moisnx/arc.git
cd arc
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
./arc
```
## macOS
```bash
# Install deps
brew install cmake ncurses yaml-cpp
# Build
git clone --recursive https://github.com/moisnx/arc.git
cd arc
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(sysctl -n hw.ncpu)
./arc
```
## Windows
```powershell
# Install vcpkg (one-time setup)
git clone https://github.com/microsoft/vcpkg.git C:\tools\vcpkg
cd C:\tools\vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg integrate install
# Install deps
.\vcpkg install pdcurses:x64-windows-static yaml-cpp:x64-windows-static
# Build
git clone --recursive https://github.com/moisnx/arc.git
cd arc
mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=C:/tools/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static
cmake --build . --config Release
.\Release\arc.exe
```
## Troubleshooting
**Missing dependencies?** See [BUILD.md](BUILD.md) for detailed instructions.
**Build errors?** Try cleaning: `rm -rf build && mkdir build && cd build && cmake ..`
**Runtime issues?** Make sure you're running the Release build, not Debug.

//! This crate provides Markdown language support for the [tree-sitter][] parsing library.
//!
//! It contains two grammars: [`LANGUAGE`] to parse the block structure of markdown documents and
//! [`INLINE_LANGUAGE`] to parse inline content.
//!
//! It also supplies [`MarkdownParser`] as a convenience wrapper around the two grammars.
//! [`MarkdownParser::parse`] returns a [`MarkdownTree`] instread of a [`Tree`][Tree]. This struct
//! contains a block tree and an inline tree for each node in the block tree that has inline
//! content.

# Building Arc Editor
Arc is a terminal-based text editor with syntax highlighting and live configuration reloading.
## Prerequisites
### All Platforms
- CMake 3.16 or higher
- C++20 compatible compiler
- Git (for cloning submodules/dependencies)
### Platform-Specific Requirements
#### Linux/Ubuntu
```bash
sudo apt update
sudo apt install build-essential cmake libncurses5-dev libncursesw5-dev libyaml-cpp-dev
```
#### macOS
```bash
brew install cmake ncurses yaml-cpp
```
#### Windows
- Visual Studio 2019 or later (with C++ workload)
- [vcpkg](https://github.com/microsoft/vcpkg) package manager
```powershell
# Install vcpkg if not already installed
git clone https://github.com/microsoft/vcpkg.git C:\tools\vcpkg
cd C:\tools\vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg integrate install
# Install dependencies (static libraries recommended)
.\vcpkg install pdcurses:x64-windows-static
.\vcpkg install yaml-cpp:x64-windows-static
```
## Dependencies Structure
The project expects dependencies in the following structure:
```
arc/
├── deps/
│ ├── tree-sitter-core/ # Tree-sitter parser library
│ ├── tree-sitter-python/ # Python language parser
│ ├── tree-sitter-c/ # C language parser
│ ├── tree-sitter-cpp/ # C++ language parser
│ ├── tree-sitter-rust/ # Rust language parser
│ ├── tree-sitter-javascript/ # JavaScript language parser
│ ├── tree-sitter-typescript/ # TypeScript parsers
│ ├── tree-sitter-markdown/ # Markdown parser
│ └── efsw/ # File system watcher library
├── src/
├── CMakeLists.txt
└── ...
```
### Cloning Dependencies
If you have submodules set up:
```bash
git clone --recursive https://github.com/moisnx/arc.git
cd arc
```
Or if you already cloned without `--recursive`:
```bash
git submodule update --init --recursive
```
## Building
### Linux/macOS
```bash
# Create build directory
mkdir build && cd build
# Configure
cmake .. -DCMAKE_BUILD_TYPE=Release
# Build
make -j$(nproc) # Linux
make -j$(sysctl -n hw.ncpu) # macOS
# Run
./arc
```
### Windows (MSVC)
```powershell
# Create build directory
mkdir build
cd build
# Configure with vcpkg toolchain
cmake .. -DCMAKE_TOOLCHAIN_FILE=C:/tools/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static
# Build
cmake --build . --config Release
# Run
.\Release\arc.exe
```
### Windows (MinGW)
```bash
mkdir build && cd build
cmake .. -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release
mingw32-make -j4
./arc.exe
```
## Build Options
### CMake Options
```bash
# Disable Tree-sitter (fallback to basic syntax highlighting)
cmake .. -DTREE_SITTER_ENABLED=OFF
# Debug build with symbols
cmake .. -DCMAKE_BUILD_TYPE=Debug
# Specify custom dependency location
cmake .. -DDEPS_DIR=/path/to/deps
```
### Tree-sitter Language Support
The build system automatically discovers available Tree-sitter language parsers in the `deps/` directory. Supported languages:
- Python
- C/C++
- Rust
- JavaScript/TypeScript/TSX
- Markdown
If a parser is not found, it will be skipped and the build will continue.
## Build Targets
```bash
# Build everything
cmake --build .
# Build specific target
cmake --build . --target arc
# Clean build
cmake --build . --target clean
# Rebuild from scratch
rm -rf build && mkdir build && cd build && cmake .. && cmake --build .
```
## Troubleshooting
### Linux: ncurses not found
```bash
sudo apt install libncurses5-dev libncursesw5-dev
```
### macOS: yaml-cpp not found
```bash
brew install yaml-cpp
```
### Windows: Missing DLLs at runtime
If using dynamic linking, copy required DLLs to the executable directory:
```powershell
# PDCurses
copy C:\tools\vcpkg\installed\x64-windows\bin\pdcurses.dll .\Release\
# yaml-cpp
copy C:\tools\vcpkg\installed\x64-windows\bin\yaml-cpp.dll .\Release\
```
**Better solution**: Use static libraries (`:x64-windows-static` triplet) to avoid DLL dependencies.
### Windows: Runtime library mismatch errors
Ensure all dependencies use the same runtime library. The project uses static runtime (`/MT`) by default.
### Tree-sitter parsers not detected (Windows)
Check that parser paths don't contain special characters. The build system should automatically handle Windows paths correctly.
### Cursor positioning issues (Windows)
Known issue with PDCurses. This is a rendering difference between PDCurses and ncurses and will be addressed in a future update.
## Installation
```bash
# Linux/macOS
sudo cmake --install . --prefix /usr/local
# Or copy manually
sudo cp arc /usr/local/bin/
# Windows - copy to a directory in your PATH
copy Release\arc.exe C:\Windows\
```
## Development Build
For faster iteration during development:
```bash
# Debug build with minimal optimization
cmake .. -DCMAKE_BUILD_TYPE=Debug
# With verbose output
cmake --build . --verbose
# Run directly from build directory
./arc # or .\Debug\arc.exe on Windows
```
## Cross-Compilation
### Linux → Windows (MinGW)
```bash
sudo apt install mingw-w64
mkdir build-windows && cd build-windows
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/mingw-w64-x86_64.cmake
make
```
## Performance Considerations
- **Release builds** are significantly faster than Debug builds
- **Static linking** produces larger binaries but has no runtime dependencies
- **Tree-sitter** adds ~5-10MB to binary size but provides superior syntax highlighting
## CI/CD Integration
Example GitHub Actions workflow:
```yaml
name: Build
on: [push, pull_request]
jobs:
build:
strategy:
matrix:
os: [ubuntu-latest, macos-latest, windows-latest]
runs-on: ${{ matrix.os }}
steps:
- uses: actions/checkout@v3
with:
submodules: recursive
- name: Install dependencies (Ubuntu)
if: matrix.os == 'ubuntu-latest'
run: sudo apt install libncurses-dev libyaml-cpp-dev
- name: Install dependencies (macOS)
if: matrix.os == 'macos-latest'
run: brew install ncurses yaml-cpp
- name: Setup vcpkg (Windows)
if: matrix.os == 'windows-latest'
uses: lukka/run-vcpkg@v11
- name: Build
run: |
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release
- name: Test
run: cd build && ctest
```
