# 04 — Implement argv parsing (tokenize command strings)
|
|
|
|
**Status:** resolved
|
|
**Blocked by:** #01
|

**Blocks:** #06

Since we're not using a shell, we need our own command-line tokenizer to split a command string into `argv[]`.
|
|
|
|
## Must handle
|
|
|
|
- Simple whitespace splitting: `ls -l /tmp` → `["ls", "-l", "/tmp"]`
|
|
- Single-quoted strings: `echo 'hello world'` → `["echo", "hello world"]`
|
|
- Double-quoted strings with escapes: `echo "hello \"world\""`
|
|
- Backslash escaping outside quotes: `echo hello\ world`
|
|
- Mixed quoting: `echo "it's a test"`
|
|
|
|
## May handle (depending on #01 decisions)
|
|
|
|
- Variable/expression interpolation: `echo $HOME` or `echo ${dir}`
|
|
- Glob expansion: `ls *.lua` (could also defer to a later issue)
|
|
|
|
## Implementation
|
|
|
|
- Standalone C module, likely `lcmd_parse.c` or part of `lcmd.c`
|
|
- Returns a `char **argv` (NULL-terminated) + argc count
|
|
- Must handle memory allocation/cleanup
