This adds very basic support for module instantiation/allocation, as
well as a stub for an interpreter (and executions APIs).
The 'wasm' utility is further expanded to instantiate, and attempt
executing the first non-imported function in the module.
Note that as the execution is a stub, the expected result is a zero.
Regardless, this will allow future commits to implement the JS
WebAssembly API. :^)
You can now watch the clipboard for changes and run a command each time
the clipboard contents change like this:
$ paste --watch some command here
The command will be spawned each time the clipboard contents change. It
can read the clipboard contents from its stdin, and CLIPBOARD_STATE
environment variable will be set to "data" if there is data to be read,
or to "nil"/"clear" if the clipboard has been cleared.
It's much better to tell the user "hey, the magic numbers don't check
out" than "oh there was a problem with your input" :P
Also refactors some stuff to make it possible to efficiently use the
parser error enum without it getting in the way.
This can currently parse a really simple module.
Note that it cannot parse the DataCount section, and it's still missing
almost all of the instructions.
This commit also adds a 'wasm' test utility that tries to parse a given
webassembly binary file.
It currently does nothing but exit when the parse fails, but it's a
start :^)
When moving multiple files by using *, e.g.,: mv * /new_path/
If there was an error while trying to move a file to the new path
the next file in the file list to be moved would have its path
incorrectly set.
- Fixed mv loop to always append the correct path to the destination
path.
- Added proper error message when mv fails.
When using open() with the O_CREAT flag we must specify the mode
argument. Otherwise we'll incorrectly set the new file's mode
to whatever is left on the stack:
courage:~ $ dd if=/dev/zero of=test count=1
1+0 blocks in
1+0 blocks out
512 bytes copied.
courage:~ $ ls -l test
--w-r-x--- 1 anon users 512 2021-05-08 01:29:52 test
courage:~ $
This also specifies the mode argument when opening files for
reading. This however is harmless because in those cases the argument
is ignored.

I noticed while testing `find` that the output of `find` contains extra
forward slashes if the root path has a trailing slash. This patch fixes
that issue by passing the root path through LexicalPath before
proceeding.
This unix classic attempts to classify and identify information about
given files based on various heuristics. In this case, we're relying on
the Core::MimeData detector for file type and LibGfx::ImageDecoder for
additional metadata if the given file is an image.
It's very simple for now, but adding new detectors should be quite easy.
This fixes extensive copying data around, and also makes head(1) in
bytes mode read exactly as much data as it needs.
Also, rename --characters to --bytes: that's exactly what it does
(actual character counting is way more complicated), and that's what
the option is called in GNU coreutils.

This changes client methods so that they return the IPC response's
return value directly - instead of the response struct - for IPC
methods which only have a single return value.
When the default build location was moved from /Build to the new
architecture specific directory, /Build/i686, this code broke.
All file names are now path relative one additional level up.
So continue the hack, and introduce another dummy directory to
make the relative paths resolve correctly.
