CMake originally links build artifacts/results so that they can run from
the target directory. As a result, it must first relink the binaries
before installation so that they can run from the installation target
directory, typically done in the preinstall stage. Ninja does not have a
preinstall stage, and the CMake code that generates the build.ninja file
does not take that into account [0].
Setting `CMAKE_BUILD_WITH_INSTALL_RPATH` [1] makes it originally link
the files with the RPATH settings for the final destination directory,
meaning that relinking is no longer needed.
Technically setting the RPATH is not required for the `fish` binary as
we do not have any relative dependencies; this is the output of
`ldd ./build/fish`:
```

/lib64/ld-linux-x86-64.so.2 (0x00007f6632600000)
```
However, since the bug only exists when the build generator is set to
ninja, the workaround is only activated for that specific build
generator to prevent any future problems.

`git push REMOTE :BRANCH` deletes remote branch BRANCH from remote
REMOTE. Should only kick in when the pattern matches, hopefully didn't
break anything else!
A large portion of time was spent constructing strings and passing
them to debug(). Turn debug into a macro so that the strings are only
constructed if they're going to be printed.
The psub tests create a fifo and launch a background job to write to it.
However fifos have this obnoxious behavior where opening the file blocks
until both sides are ready. In one of the tests we don't actually read
from the fifo we create, so the background job hangs, and the tests
never complete. Fix this by just reading from the fifo.
This adds a new class arg_iterator_t which encapsulates decisions about
whether to read arguments from stdin or argv. It also migrates the
unread bytes buffer from a static variable to an instance variable.
* Add eopkg support
Add support for eopkg in __fish_print_packages function, and
add new completion eopkg.fish in share/completions
* Sorry for the empty file
* Sorry for the empty file again
* Use builtin function for checking subcommand and options
* Fix description
* Use string function to replace grep and cut
* Add completion for search command
This was caused by it prepending "-s" to argv always,
and later checking $argv[1].
As it turns out, that is kinda superfluous, so we can just add "-s" to
the `bind` calls.
Also adjust the tests so the vi-bindings are enabled via the function,
which would have caught this.
Fixes#4494.
Profiling with callgrind revealed that about 60% of the time in a `something | string match` call
was actually spent in `string_get_arg_stdin()`,
because it was calling `read` one byte at a time.
This makes it read in chunks similar to builtin read.
This increases performance for `getent hosts | string match -v '0.0.0.0*'` from about 300ms to about 30ms (i.e. 90%).
At that point it's _actually_ quicker than `grep`.
To improve performance even more, we'd have to cut down on str2wcstring.
Fixes#4604.
Muparser Exceptectomy
This removes large pieces of muParser that fish does not use, such as its optimizer. It also switches muParser from throwing exceptions to propagating errors explicitly.
This is a very strange design that determines whether initialization
needs to be performed by reassigning a function pointer. A misguided
optimization? Just check explicitly.
