This class had slightly confusing semantics and the added weirdness
doesn't seem worth it just so we can say "." instead of "->" when
iterating over a vector of NNRPs.
This patch replaces NonnullRefPtrVector<T> with Vector<NNRP<T>>.
This is not guaranteed to always work correctly as ArgsParser deals in
StringViews and might have a non-properly-null-terminated string as a
value. As a bonus, using StringView (and DeprecatedString where
necessary) leads to nicer looking code too :^)
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.
With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.
That is, return ErrorOr<int>, handle fallible ops with TRY() and accept
a Main::Arguments.
Note that we do not populate the argc/argv members of Main::Arguments,
so all accesses have to go through .strings.
Note that the default shellrc is most likely not valid posix sh code, so
passing --skip-shellrc is suggested until we come up with a separate
shellrc file for the POSIX parser to use when interactive.
The parser is still very much a work-in-progress, but it can currently
parse most of the basic bits, the only *completely* unimplemented things
in the parser are:
- heredocs (io_here)
- alias expansion
- arithmetic expansion
There are a whole suite of bugs, and syntax highlighting is unreliable
at best.
For now, this is not attached anywhere, a future commit will enable it
for /bin/sh or a `Shell --posix` invocation.
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.
We changed elapsed() to return i64 instead of int as that's what
AK::Time::to_milliseconds() returns, causing a bunch of implicit lossy
conversions in callers. Clean those up with a mix of type changes and
casts.
In 7c5e30daaa, the focus was "only" on
Userland/Libraries/, whereas this commit cleans up the remaining
headers in the repo, and any new badly-formatted include.
The builtin is based on the behaviour of the z-shell.
Namely it tries to resolve every argument one by one.
When resolving (in the order below) the following results can occur:
1. The argument is a shell built-in command. Then print it.
2. The argument is an alias. In this case we print the mapped value.
3. The argument was found in the `PATH` environment variable.
In this case we print the resolved absolute path
and try to find more occurences in the `PATH` environment variable.
4. None of the above. If no earlier argument got resolved,
we print the error `{argument} not found`.
If at least one argument got resolved we exit with exit code 0,
otherwise 1.
By not using Core::File to resolve the executable in the environment
but rather using a modified version of the code we print every
matching executable of the given name. This behaviour matches
up with the z-shell.
The builtin has the following flags to modify the behaviour according
to the users needs:
- `-p --path-only`: This skips the built-in and alias checks
(step 1 & 2)
- `-s --follow-symlink`: This follows the symlinks of an executable to
its symlink-free location.
- `-w --type`: This displays the type of the found object
without any additional descriptive information.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
Also do this for Shell.
This greatly simplifies the CMakeLists in Lagom, replacing many glob
patterns with a big list of libraries. There are still a few special
libraries that need some help to conform to the pattern, like LibELF and
LibWebView.
It also lets us remove essentially all of the Serenity or Lagom binary
directory detection logic from code generators, as now both projects
directories enter the generator logic from the same place.
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.
