# Ecex
Ecex is a small C editor with GLFW/OpenGL rendering and C config/plugins loaded
through CCDJIT.
## Build
Dependencies:
- `clang`
- `make`
- `pkg-config`
- GLFW 3
- OpenGL
Build and test:
```sh
make
make check
```
With Guix:
```sh
guix shell -m manifest.scm -- make check
guix build -f guix.scm
```
Run:
```sh
make run
```
Use a config or font explicitly:
```sh
./bin/ecex --config config/ecexrc.c
./bin/ecex --font /path/to/font.ttf
```
Install locally:
```sh
make install PREFIX=$HOME/.local
```
`ECEX_FONT` can also point at a TTF font. `ECEX_INCLUDE` can point at the Ecex
include directory when loading configs from another working directory.
## Useful Keys
- `M-x`: command prompt
- `C-x C-f`: find file
- `C-x C-s`: save buffer
- `C-x b`: switch buffer
- `C-x k`: kill buffer
- `C-x d`: file browser
- `M-x messages`: open the read-only `*Messages*` buffer
- `C-s` / `C-r`: incremental search
- `C-/`: undo
- `C-S-z`: redo
- `C-x C-r`: reload config
- `C-x C-c`: quit
The sample config in `config/ecexrc.c` enables demo plugins including Markdown,
which-key, C mode, API completion, render demo, and Tetris.
## Development
`make check` runs the core C tests. `make sanitize` builds the app and runs the
tests with AddressSanitizer/UBSan flags.
Plugin API conventions are documented in `docs/plugin-api.md`. Current CCDJIT
follow-up work is tracked in `docs/ccdjit-improvements.md`.
`guix.scm` defines a local package. It installs the binary, public headers,
sample configs, and docs, and wraps `ecex` with `ECEX_INCLUDE` and a DejaVu font
path.
