There's a terrible number of fishscripts that start with
set path (dirname (status filename))
And that's really just a bit boring.
So let's let it be
set path (status dirname)
This reverts commit 1b0ec21773.
"Interactive" has multiple meanings here, one of them being "the whole shell" is interactive, which `status is-interactive` tests, and one "this interaction is interactive", which happens when `read`ing in a script.
Fixes#7080.
This change is necessary to fix dynamic titles for the Alacritty
terminal. We do this by simply adding the (wchar_t *) literal
L"alacritty" to the end of the title_terms array. This variable is
ultimately used in the subsequent function
does_term_support_setting_title (dtsst) for the purposes of whitelisting
certain terminals.
If an Alacritty user does not have the terminfo for alacritty present in
their terminfo database, Alacritty sets the TERM variable to
"xterm-256color", but if the terminfo for Alacritty is present, TERM is
instead set to "alacritty".
Prior to this change, none of the "fallback patterns" in the dtsst
function (which is used to ultimately decide whether or not a given
value of the TERM environment variable is supported) would apply to a
value of "alacritty". Ordinarily, the dtsst function would return true
if nothing matches, but one of the final checks involves testing the
result of ttyname_r to see if it contains the substring "tty", which
causes dtsst to return false. In the case where TERM="alacritty", this
is erroneous, because Alacritty does, indeed, support changing its title
and will also silently ignore attempts to change the title if that
behavior has been disabled by the user [1].
The changed file, src/env_dispatch.cpp, was reformatted by clang-format
in accordance with the documented procedures for contributors.

When fish exits, it tries to restore the foreground process group.
However this may actually steal control of the fg process group
from another process. Fix this by clearing the SIGTTOU handler so
that tcsetpgrp() will fail.
Credit to @mqudsi for awesome debugging.
Fixes#7060
Prior to this change, if the user's prompt was wider than the terminal, we
would reduce it to just `> `. With this change, attempt to truncate the
prompt.
For each line of the prompt, calculate its width. If the width exceeds
COLUMNS, prepend ellipsis to that line, and start removing characters
until it fits. Escape sequences are skipped.
Fixes#904
Initially I wanted to pick a different name to avoid confusion with
process groups, but really job trees *are* process groups. So name them
to reflect that fact.
Also rename "placeholder" to "internal" which is clearer.
Prior to this, jobs all had a pgid, and fish has to work hard to ensure
that pgids were inherited properly for nested jobs. But now the job tree
is the source of truth and there is only one location for the pgid.
job_lineage was used to track "where jobs came from" but the job tree idea is
a better abstraction. It groups jobs together similar to how a process group
would in other shells. Begin to remove the notion of lineage.
Job trees come in two flavors: “placeholders” for jobs which are only fish
functions, and non-placeholders which need to track a pgid. This adds
logic to allow a job to decide if its parent's job tree is appropriate,
and allocating a new tree if not.
job_tree represents the data that should be shared between a job and any
jobs that may be spawned by functions or eval run as part of that job. It
reifies shared data that before was handled piecemeal.
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.
Currently fish aborts execution mid-pipeline if a file redirection
failed, which can leave the shell in a broken state (job abandoned after
giving control of the terminal to an already-executed job in the
pipeline).
This patch replaces a failed fd with a closed fd and continues execution
if the affected process wasn't the first in the pipeline.
While this is a hack to address the regression behind fish-shell/#7038
introduced in d62576c, it can also be argued that this behavior is
actually more correct... right?
Closes#7038.
* Add an "_" builtin to call into gettext
We already have gettext in C++ (if available), so it seems weird to
fork off a command to start it from script.
This is only for fish's own translations. There's no way to call into
other catalogs, it just translates all arguments separately.
This is faster by a factor of ~1000, which allows us to call
translations much more, especially from scripts.
E.g. making fish_greeting global by default would hurt cost-wise,
given that my fish starts up in 8ms and just calling the current `_`
function takes 2ms, and that would have two calls.
Incidentally, this also makes us rely on a weirdly defined function
less, so it:
Fixes#6804.
* docs: Add `_` docs
Let's see if that filename works out.
* Reword _ docs
This is a function you can either execute once, interactively, or
stick in config.fish, and it will do the right thing.
Some options are included to choose some slightly different behavior,
like setting $PATH directly instead of $fish_user_paths, or moving
already existing components to the front/back instead of ignoring
them, or appending new components instead of prepending them.
The defaults were chosen because they are the most safe, and
especially because they allow it to be idempotent - running it again
and again and again won't change anything, it won't even run the
actual `set` because it skips that if all components are already in.
Fixes#6960.
