Edit - Extended Syntax Highlighting Fork

A simple terminal-based text editor with extensive syntax highlighting support.

This is a fork of Microsoft's Edit that adds modern syntax highlighting for 19 programming languages. The editor pays homage to the classic MS-DOS Editor, but with a modern interface and input controls similar to VS Code

This is a mirrored version of my fork present on Modding Forge - Code. If you want the binaries you can download them here

This fork extends the original Edit with comprehensive syntax highlighting support for additional programming languages and markup formats.

All lexers implement high-performance byte-level parsing with:

• Zero-copy tokenization - Direct byte slice processing
• Context-aware highlighting - Language-specific features
• Multi-line support - Block comments, strings, heredocs
• Escape sequences - Proper handling of string escapes

You can download binaries from the Releases page or build from source.

Requirements:

• Rust (nightly toolchain recommended)
• Git

# Clone the repository
git clone <repository-url>
cd edit

# Build release version
cargo build --release --package edit

# Binary will be in target/release/edit

# Open a file
edit filename.rs

# Create new file
edit newfile.py

Keyboard Shortcuts:

• Standard shortcuts similar to VS Code and modern editors
• Full terminal compatibility with support for mouse input
• Context menus and dialog boxes for common operations

This fork is based on Microsoft Edit v1.2.1.

Original features include:

• Simple, accessible terminal-based editor
• Modern UI inspired by MS-DOS Editor
• Cross-platform support (Windows, Linux, macOS)
• Optional ICU integration for advanced text operations

This project optionally depends on the ICU library for Search and Replace functionality. By default, the project looks for a SONAME without version suffix:

• Windows: icuuc.dll
• macOS: libicuuc.dylib
• UNIX: libicuuc.so

If your installation uses a different SONAME, set these environment variables at build time:

• EDIT_CFG_ICUUC_SONAME: e.g., libicuuc.so.76
• EDIT_CFG_ICUI18N_SONAME: e.g., libicui18n.so.76

For versioned exports:

• EDIT_CFG_ICU_CPP_EXPORTS: Set to true for C++ symbols (default on macOS)
• EDIT_CFG_ICU_RENAMING_VERSION: Version number for suffixed symbols
• EDIT_CFG_ICU_RENAMING_AUTO_DETECT: Auto-detect version at runtime (UNIX only)

Test your ICU configuration:

cargo test -- --ignored
