* Add/update doc commentsRory Dudley2024-06-301-3/+6
| | | | | This patch update a ton of the documentation comments throughout the codebase, refactoring some areas, and adding new comments to others.
* Updated the way built-in commands are called/usedRory Dudley2024-06-041-11/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, built-in commands were fairly primitive, merely outputting STDOUT and STDERR with the print! macros. However, we need them to behave like normal programs, that is: - Acknowledge their verse's meter (forking, piping, etc.), - Ability to capture STDOUT and STDERR (>, 2>), - and Affect the currently running environment. For these reasons, the anthology was reworked, and now contains the Anthology struct, which mimics both std::process::{Child, Command}. The AnthologyStdin helper struct was also created, for built-ins to take input on STDIN, though no built-in is currently using it. Each built-ins' incant functions were updated to return a std::process::Output. It contains output from STDOUT, output from STDERR, and the exit code of the "process". A fix was also implemented for aliases, where the STDOUT and STDERR vectors were not being copied to the newly constructed verse. Notes: There is some cleanup that needs to happen on this patch. For one, the spellcheck function is no longer being used, so there is a generic OS error if the program cannot be found in the $PATH. Also, anthology::lookup gets called twice, which shouldn't need to happen.
* Add docstring comments to all the anthology functionsRory Dudley2024-03-311-0/+11
| | | | | | Add docstring comments for all the incant function throughout the anthology, documenting what each function does, and an example of it's shell command.
* Replace env!("HOME") with env::var("HOME")Rory Dudley2024-03-301-1/+8
| | | | | | Replaced all (non-test) instances of env!("HOME") with env::var("HOME"). The env! macro should only be used in instances where the environment variable should be resolved during compile time.
* The anthology moduleRory Dudley2024-03-281-0/+20
The anthology module was added to run built-in commands. The 'cd' and 'exit' built-ins were moved from the main recite() loop to this module. Additionally, the 'export' and 'source' built-ins were added.
