Dream Editor for a TExt Yo

DETEY - is a small, text editor by Tsoding (with my improvements).

Syntax highlighting, minimalistic file browser and GPU-backed text rendering. It is implemented in portable C and uses SDL2, FreeType and GLEW for windowing, font rasterization and OpenGL.

Highlights

• Fast glyph atlas based text rendering (see free_glyph_atlas_render_line_sized)
• Simple software lexer for basic C/C++ token highlighting (see lexer_next)
• Camera-driven UI with a tiny renderer abstraction (see renderer_init)
• Editor core with selection, search, file IO and cursor movement (see editor_render, editor_save)
• Minimal file browser implemented in src/fs/file_browser.c

Quick start

POSIX:

./build.sh
./detey src/main.c

Windows (MSVC):

.\setup_dependencies.bat
.\build_msvc.bat
.\detey.exe src\main.c
