Small touches to multiple locations in base.
Nothing major
|
|
Completes the port to our standard library (up to malloc).
|
|
Commented out libc includes to uncover all explicit dependencies.
A large fraction has now been ported over (no testing).
I did not port over the command line tools, such as the rc shell.
These will be done independently - as of now I just want the library to
stand independent.
Compilation currently fails due to the lack of math functions.
|
|
Additionally, fixed varargs cleanup when done with fmt.write.
Some system constants were added to allow for directory walking.
|

The old methods were simple wrappers of C standard library functions.
We've moved (painfully) over to a new interface that allows for files to
live on the stack. All users of the functionality are ported over.
|
|
Also updated libraries in makefiles that were deprecated.

I found the split to be arbitrary. Better to include the functionality
in the standard library. I also split the headers to allow for more
granular inclusion (but the library is still monolithic). The only
ugliness is the circular dependency introduced with libutf's generated
functions. We put explicit prereqs with the necessary object files
instead.

Heredocs are simply strings written to tmp files.
There was minimal bug testing here.
Also, various bug fixes are included

|

However, it is not tested in the slightest.

Introduced shell globbing

Unsure about my modification to the language. I found the parsing of the
case body within switches to be odd - specifically that it parses
liberally and then checks that it has case -> cmd structuring while it
walks the code. This means the language is more permissive than the
semantics. I modified it to be more explicit, but at the cost of having
to end each case statement with a semicolon. I wanted a colon, but this
is a valid word character and thus will be lexed as part of the word.
