Currently, if a "return" is given outside of a function, we'd just
throw an error.
That always struck me as a bit weird, given that scripts can also
return a value.
So simply let "return" outside also exit the script, kinda like "exit"
does.
However, unlike "exit" it doesn't quit an interactive shell - it seems
weird to have "return" do that as well. It sets $status, so it can be
used to quickly set that, in case you want to test something.
Today the reader exposes its internals directly, e.g. to the commandline
builtin. This is of course not thread safe. For example in concurrent
execution, running `commandline` twice in separate threads would cause a
race and likely a crash.
Fix this by factoring all the commandline state into a new type
'commandline_state_t'. Make it a singleton (there is only one command
line
after all) and protect it with a lock.
No user visible change here.
No functional change here; this migrates the fix ensuring that history
items are available in the builtin interactive read command into the
reader itself, in preparation for removing reader_get_history().
Still not happy with this, it's overwhelming!
Might have to split this into two - one with simple paths and rough
descriptions, and one with the full scoop for experts?
This was a workaround for an error that has been removed in glibc
2.32 (by removing sys_errlist and friends, which it complained about).
Other than that, it's an attempt at performance optimization that
should just be fixed at the system level - if your linker is bad,
replace it with a better linker. No need for fish to work around it.
Closes#8152
Cmake accepts both absolute and relative paths in CMAKE_INSTALL_DATADIR.
For the latter case CMAKE_INSTALL_PREFIX is being prepended
automatically. %{rel_datadir} is derived from CMAKE_INSTALL_DATADIR
which was assumed to be relative and otherwise causes issues in a .pc
file where prefix is being prepended unconditionally.
Make sure %{rel_datadir} is relative by calculating RELATIVE_PATH from
CMAKE_INSTALL_PREFIX to CMAKE_INSTALL_FULL_DATADIR which is known to be
absolute.
Fixes#8150
For builtins that have the same name as common commands, it might not
be entirely obvious that there is another page.
So, for those builtins, we add a note, but only in the man pages.
(exception is true and false because the note would be longer than the
page, and it's fridging true and false)
Fixes#8077.
This injected filenames into fish script, which could inject things
that looked like fish script.
E.g. create a file called `~/.config/fish/themes/"; rm -rf ~/*"`.
Note that the prompts are all shipped by us, but the themes can
technically be added by the user, and they might not be dilligent in
what filenames they allow.
`fish_config theme`:
- `list` to list all available themes (files in the two theme
directories - either the web_config/themes one or
~/.config/fish/themes!)
- `show` to show select (or all) themes right in the terminal - this
starts another fish that reads the theme file and prints the sample
text, manually colored
- `choose` to load a theme *now*, setting the variables globally
- `save` to load a theme and save the variables universally
- `dump` to write the current theme in .theme format (to stdout)
- `demo` to display the current theme
