A small interactive command line for Zig programs.
Every microcontroller project I do ends up with a command shell on the UART. This is an implementation of a similar system in zig.
Note: zig-embshell is my first ever program in zig. For me, it's a learning exercise.
Developed with zig 0.11.0-dev.1457+cb9d00e1a
zig build run
Edit src/cmds.zig
Each handler is registered in cmdTable which is const and constructed at comptime. Every handler is passed argc (the number of arguments) and an argv array. argv[0] is the command name, the arguments follow.
- Basic tab completion (command names only)
- Backspace for basic line editing
- Learn some zig
- Be reasonably readable
- Target a tiny system with no heap
- Keep term.zig small and portable
- Don't be readline/linenoise (no history, nothing fancy)
- No live adding of new commands, everything compiled in
