Ali Mohammad Pur	d56fbaa7e8	Shell: Allow underscores in normal expansion names	2023-02-18 06:55:46 +03:30
Ali Mohammad Pur	a6d77162f4	Shell: Correctly keep track of special parameter length ... We were previously treating special expansions (e.g. $#) as zero-length expansions, which made the shell repeat them literally after expanding them.	2023-02-18 06:55:46 +03:30
Ali Mohammad Pur	6da438e992	Shell: Clear expansions after committing a word in the POSIX parser	2023-02-18 06:55:46 +03:30
Ali Mohammad Pur	2881bb4c3a	Shell: Add support for heredocs to the POSIX parser	2023-02-18 06:55:46 +03:30
Ali Mohammad Pur	2a276c86d4	Shell: Start implementing a POSIX-compliant parser ... The parser is still very much a work-in-progress, but it can currently parse most of the basic bits, the only *completely* unimplemented things in the parser are: - heredocs (io_here) - alias expansion - arithmetic expansion There are a whole suite of bugs, and syntax highlighting is unreliable at best. For now, this is not attached anywhere, a future commit will enable it for /bin/sh or a `Shell --posix` invocation.	2023-02-13 23:00:15 +03:30
