Released under the Python Software Foundation License, this one
doesn't look awful (no green top bar, huzzah!).
Lightly forked it to remove the donation footer (we don't take any)
and to change the python references to fish references.
The image is just our favicon, which is a stylized "f" and therefore
not fantastic (are we facebook?), but it's the best I found, and the
thing before had no images at all.
Fixes#6500
(as far as I'm concerned)
In the new __fish_apropos, makewhatis is run explicitly to generate the
whatis database. However this can be a little slow. Run it in the
background, after the apropos call completes so as to avoid a weird
race.
This means that descriptions may not be available the first time the
user invokes it, but that's better than appearing to hang for a while.
override MANPATH used by apropos with local whatis database and update it once a day
get rid of xargs
Created __fish_apropos and fixed __fish_complete_man to use that as well
moved macos apropos comment
On WSL1, fcntl(F_SETOWN) will fail and this would report an error.
Suppress this error message since it is not very interesting.
The effect is to disable real-time universal variable propagation.
Introduce a new strategy for notifying other fish processes of universal
variable changes, as a planned replacement for the complex
strategy_named_pipe. The new strategy still uses a named pipe, but instead
of select() on it, it arranges for SIGIO to be delivered when data is
available. If a SIGIO has been seen since the last check, it means the file
needs to be re-read.
When expanding a string, you may or may not want to generate
descriptions alongside the expanded string. Usually you don't want to
but descriptions were opt out. This commit makes them opt in.
If the padding is not divisible by the char's width without remainder,
we pad the remainder with spaces, so the total width of the output is correct.
Also add completions, changelog entry, adjust documentation, add examples
with emoji and some tests. Apply some minor style nitpicks and avoid extra
allocations of the input strings.
Technically the equivalence would be something like
string length -q $str
test -n (string join \n -- $str | string collect)
To handle when str has multiple empty strings;
but quoting is easier to remember and enough for most practical purposes.
fish wants to build with -mmacosx-version-min=10.9. This is important
because it ensures that we do not use functions or linker features which
which are not available on 10.9. However this collides with the fact
that fish also prefers to use a pcre2 package installed on the system,
which is typically built for that system.
Mac ld will (rightly) complain when it sees a 10.9-targeted binary
linking a 10.15-targeted dylib. This is an annoying warning that gets
emitted on every build.
We could fix this either having Mac builds prefer the vendored PCRE2
by default, or by having debug builds target the system version. But
we want to continue to default to system PCRE2 and we don't want to risk
losing compatibility with older Mac versions. So we will just suppress
all linker warnings in Mac debug builds.
Improves on #7328.
I believe this is the correct behavior, simply skip all whitespace before
a word. Try with
./fish -C 'bind \ef forward-bigword; bind \eb backward-bigword; bind \ed kill-bigword; bind \cw backward-kill-bigword'
Also unrelated formatting fixes. I don't think a CI failure on unformatted
code is warranted but I wish it could do that behind the scenes.
For example "grep --color"<TAB> can complete to "grep --color=". Don't add
a space in this case; we do the same for arguments that end in =.
In GNU-style getopt, equal sign means that the flag has an argument. Without
the = it would not consume the next argument as opposed to Python's argparse.
This was a weird special behavior where we'd put the commandline on a
new line if it wrapped *and* the prompt was > 33% of the screen.
It seems to be more confusing than anything.
Fixes#5118.
Prior to this change, tab completing with a variable assignment like
`VAR=val cmd<tab>` would parse out and apply VAR=val, then recursively
invoke completions. This caused some awkwardness around the wrap chain -
if a wrapped command had a variable completion we risked infinite
recursion. A secondary problem is that we would run any command
substitutions inside variable assignment, which the user does not expect
to run until pressing enter.
With this change, we explicitly track variable assignments encountered
during tab completion, including both those explicitly given on the
command line and those found during wrap chain walk. We then apply them
while suppressing command substitutions.
In preparation for applying variable assignments (VAR=VAL cmd), separate
them out from the command when performing completions. This includes both
those that the user typed, and any that come about through
completion --wraps.
When completing and walking a wrap chain, we pass around a lot of
information. Factor this together into a new struct custom_arg_data_t
which reduces the number of parameters needed.
