__fish_apropos is a huge hack under macOS and it seems that it's either broken
or man pages are missing/not indexed under CI. In all cases, hard-code the
results of __fish_describe_command to test the integration machinery
specifically and get the test to pass under macOS CI.
Command completion descriptions were not being generated from `apropos`. Well,
they were being generated but that was not being correctly used by fish core.
Not sure when this was broken, but there's a possibility it was during the rust
port.
In addition to simply not working, it seems the old code tried to avoid
allocations but String::split_at_mut() allocates a new string (since one
allocation from the global allocator can't be split into two allocations to be
freed separately). Use `String::as_mut_utfstr()` before splitting the &wstr
instead of splitting the &str to actually do this alloc-free.
This was vexing me for a while because the extraneous output presented as a
valid (but unwanted) completion, i.e. with RUSTC_WRAPPER exported, `env RUSTC_W`
would offer `RUSTC_W=` and `RUSTC_WRAPPER=` as completions (when only the latter
should have been offered up).
This blames to a40b019, when @floam made some changes to various completions,
but this one seems to not quite fit the pattern and had a copy/paste error
resulting in using an undeclared variable.
Also disable filename completion on port.
__kld_whatis is an order of magnitude faster than calling `whatis` by means of
`__fish_whatis`. (It could be even faster if we could somehow tell `string
replace` to return after the first result, since the .Nd line comes at the start
of the file.)
It still takes some ~3.5 to print descriptions for all available klds (864 under
FreeBSD 13), so we still need to decide when it's prudent to do so and when it's
not.
The "principal" parser is the one and only today; in the future we hope to
have multiple parsers to execute fish script in parallel.
Having a globally accessible "principle" parser is suspicious; now we can
get rid of it.
The "principal" environment stack was the one that was associated with the
"principal" parser and would dispatch changes like to TZ, etc.
This was always very suspicious, as a global; now we can remove it.
Prior to this commit, there was a stack of ReaderDatas, each one has a
reference to a Parser (same Parser in each, for now). However, the current
ReaderData is globally accessible. Because it holds a Parser, effectively
anything can run fish script; this also prevents us from making the Parser
&mut.
Split these up. Create ReaderData, which holds the data portion of the
reader machinery, and then create Reader which holds a ReaderData and a
Parser. Now `reader_current_data()` can only return the data itself; it
cannot execute fish script.
This results in some other nice simplifications.
This is a start on untangling input. Prior to this, a ReaderData and an
Inputter would communicate with each other; this is natural in C++ but
difficult in Rust because the Reader would own an Inputter and therefore
the Inputter could not easily reference the Reader. This was previously
"resolved" via unsafe code.
Fix this by collapsing Inputter into Reader. Now they're the same object!
Migrate Inputter's logic into a trait, so we get some modularity, and then
directly implement the remaining input methods on ReaderData.
* completions/magento: Fixes module aggregation for module related commmands
Previousely when attempting completion for commands `module:enable`,
`mmodule:disable` and `module:uninstall` and error would be disaplyed,
stating that "magento" was not found.
Upon inspection of the issue in the related completion script it became
clear that:
1. The shell command `magento` does not exist as the CLI script of
Magentoresides under `bin/magento`.
2. The module aggregation would not work after referncing the
appropriate CLI command as an undeclared variable was being
introspected.
3. Using Magento's CLI command took too long to respond as it has to
bootstrap the whole Magento stack in order to deliver modules.
Thus the whole aggregation was rewritten to a form that actually works
and reduces the aggregation to reading the appropriate information
directly from the configuration file, provided that the file exists and
PHP is installed.
* completions/magento: Refactors module aggregation for module related commmands to not use PHP script
Executing random scripts from fish completion poses a threat to the
system. While this would indicate that the Magento installation has been
corrupted, it still is better to not run `app/etc/config.php` to get
hold of the modules.
Thus the module aggregation was rewritten to make use of `sed` instead,
which has the additional benefit of being faster than using PHP.
Add round options, but I think can also add floor, ceiling, etc. And
the default mode is trunc.

A few specific tests fail under i586 due to its inherent floating point
inaccuracy issues (rust-lang/rust#114479), so ignore these tests if certain
are met.
We have specific integration tests elsewhere in fish to check that even under
i586 we get mostly sane results, so this is OK. I tried to modify the assert
macros to check for a loose string match (up to one character difference) or an
f64 abs diff of less than epsilon, but it was a lot of code with little value
and increased the friction to contributing to the tests. Also, let's just
acknowledge the fact that all of i686, let alone i586 specifically, is a dead
end and not worth investing such time and effort into so long as it more or less
"works".
Closes#10474.
Due to the inherent floating point accuracy issues under i586 described
in #10474 and at https://github.com/rust-lang/rust/issues/114479, we need to add
a workaround to our littlecheck math tests to perform less stringent comparisons
when fish was built for x86 without SSE2 support.
This commit addresses the littlecheck issues that caused #10474 to be re-opened,
but I still have to reproduce the cargo test failures for
`negative_precision_width`, `test_float`, `test_float_g`, and `test_locale`.
The CMake `cargo test` integration was broken if Rust_CARGO_TARGET were used
with `CARGO_FLAGS` set to `-Zbuild-std` (e.g. to target i586 under i686 without
the i586 toolchain installed).
