SRCINFO_BASH is a one file sourced library for bash that parses SRCINFO files into native bash dictionaries.
Include/source the entire src/srcinfo.sh file in your script, and run the function srcinfo.parse. It can take the optional flag -p to enable pacstall compatibility. The function has 2 required arguments, that being the path to the SRCINFO file, and a variable prefix, useful for avoiding variable name clashes. The function can return a variety of return codes, so you should know about what each one does:
| Error Code | Description |
|---|---|
| 1 | No file passed |
| 2 | Invalid parameter passing |
| 3 | Could not parse a valid key value pair |
| 4 | Could not parse a valid value |
| 5 | Empty file passed |
If you get 0, congratulations, you parsed a file! Since Bash doesn't have good support for anything past a simple dictionary, you're gonna have to parse some stuff yourself after, but here's how you would access something like pkgbase->source->[1]:
First to get pkgbase, you must access an associated array named {var_prefix}_access_pkgbase[pkgbase], which will contain the name of the array that you must access to get to that package contents, which is {var_prefix}_pkgname, another associated array which contains package information. If a key is an array, it will look like this:
SRCINFO_ARRAY_REDIRECT:array_name
Where array_name is the name of the array containing those values.
If -p is passed, the first step is irrelevant, so you can start with the second associated array, that being {var_prefix}_pkgname_inner.
This library does not check the validity of an SRCINFO file, please use another tool if that is important to you; likewise, this library also does not care about the SRCINFO specification, with the exception of the two sentences about blank lines, comments, and indentation. Whatever this library finds as a key, it will parse.
