This is fairly subtle.
When installable, and we either can't find the version file or it is
outdated, we ask the user to confirm installation (just like `--install`).
We do that only if we are really truly interactive (with a tty!) to
avoid `fish -c` running into problems.
This check could be tightened even more, because currently:
```fish
fish -ic 'echo foo'
```
asks, while
```fish
fish -ic 'echo foo' < /dev/null
```
does not.
`fish -c` will still error out if it can't find the config, but it
will just run if it is out of date.
This is unfortunately necessary, because otherwise it would not rerun
the build script just because you installed sphinx.
Because we use the man pages for --help output, they're pretty
necessary.
To override it, you can set $FISH_BUILD_DOCS=0, like
```fish
FISH_BUILD_DOCS=0 cargo install --path .
```
I think we can now call what we have in git better than the last
C++-based release, and you'll still need a C compiler to build it
because we still have some C code (libc.c).
It appears we can't find a system that ships rustc >= 1.67 and < 1.70,
so keeping it at 1.67 gains nothing.
1.70 is used in Debian 13, so that will be able to build fish out of
the box (12 was on 1.63 which was already too low).
Fish functions are great for configuring fish but they don't integrate
seamlessly with the rest of the system. For tasks that can run outside fish,
writing scripts is the natural approach.
To edit my scripts I frequently run
$EDITOR (which my-script)
Would be great to reduce the amount typing for this common case (the names
of editor and scripts are usually short, so that's a lot of typing spent on
the boring part).
Our Alt+o binding opens the file at the cursor in a pager. When the cursor
is in command position, it doesn't do anything (unless the command is actually
a valid file path). Let's make it open the resolved file path in an editor.
In future, we should teach this binding to delegate to "funced" upon seeing
a function instead of a script. I didn't do it yet because funced prints
messages, so it will mess with the commandline rendering if used from
a binding. (The fact that funced encourages overwriting functions that
ship with fish is worrysome. Also I'm not sure why funced doesn't open the
function's source file directly (if not sourced from stdin). Persisting the
function should probably be the default.)
Alternative approach: I think other shells expand "=my-script" to
"/path/to/my-script". That is certainly an option -- if we do that we'd want
to teach fish to complete command names after "=". Since I don't remember
scenarios where I care about the full path of a script beyond opening it in
my editor, I didn't look further into this.
Closes#10266
This is awkward because some systems really want $SHELL to be
sh-compatible, it's also duplicated with the actual docs and not
really something you have to do in the first five minutes of using
fish.
Supersedes #10229
Apparently this is actually a point of confusion.
Unfortunately we can't use `which` here because 1. it might not be
installed, 2. it might be trash.
So we give instructions from inside fish, and explain that they
should *typically* work.
See #10002
Stackoverflow's fish tag suffers from inconsistent moderation and an
annoying policy on what is allowed and what isn't.
Given that fish straddles the line between "programming" and "usage",
some fish questions would be allowed and some wouldn't, and it is
awkward for users to tell which.
So stop recommending a site that, in practice, closes user's questions
for unclear reasons.
This needs to be done for fish-site as well.
* add support for colorized ls on openbsd
* add changelog line for colorls support
* add readme line for colorls support
* determine ls command at runtime, don't cache it
* eliminate __fish_ls_command function
This was removed from fish-site in
7c19bf2cc9a3742346527cd6979671f16b8caeb9 because it's out of date, so
it gives a bad first impression.
In my tests it also loads very slowly and features oh-my-fish instead
of a stock fish.
We use sphinx with rst for our documentation, and github supports rst
here, so it seems weird to have markdown just for these.
It also allows us e.g. to include the CHANGELOG in the docs without
requiring another build dependency.
