2021-11-11chore: libunicode -> libutfNicholas
2021-11-08feat(rc): added back functionality of prompt, now unicode awareNicholas Noll
2021-10-29Prototype of unicode readline supportNicholas Noll
The readline functionality operated on the assumption that 1 byte = 1 character. This is obviously wrong if you input a non-ascii character. This commit temporarily removes a lot of functionality but parses input bytes in a unicode-aware manner. The outstanding problem now is 1 unicode rune != 1 column. There are double wide characters, as well as zero width runes, that further break our assumption that 1 rune = 1 character = 1 column. This is the next iteration.
2021-10-26Feat(libunicode): Added an explicit unicode libraryNicholas Noll
Refactored code to pull out utf8 functions from base into a standalone library. Also left the required function inside arg.c so that code that calls ARG_BEGIN doesn't have to link to libunicode.
2021-10-26fix(rc): prompt during command entryNicholas Noll
2021-10-26feat(rc): keywords now recognized. for and while loopNicholas Noll
Prototypes for loops sketched. This required recognizing keywords and returning from yylex. Debugging/testing will be required.

2021-10-20Refactored interactivity to track with thread.Nicholas Noll
Hit a bit of a stopping point. Specifically, the way XAsync runs currently is by forking the execution context and having the child run the async code while the parent runs the remainder. The problem with this architecture is it doesn't interact well with job control. When we fork, we create a new process group. Thus the Xasync fork becomes the new leader. In short, our traversal of the parse tree as to be less "preorder" and more "in order", i.e. from the leaves up. The "left" command of the pipeline should be the "leader" of the process group.
2021-10-19Feat(rc): added subshell commands and cd builtinNicholas Noll
Slowly chipping away at a decent feature list. Subshell commands are executed by @{ ... }.
