This adds flags --path and --unpath to builtin set, analogous to
--export and --unexport. These flags change whether a variable is
marked as a path variable.
Universal variables cannot yet be path variables.
This switches quoted expansion like "$foo" to use foo's delimiter instead of
space. The delimiter is space for normal variables and colonf or path variables.
Expansions like "$PATH" will now expand using ':'.
This commit begins to bake in a notion of path-style variables.
Prior to this fix, fish would export arrays as ASCII record separator
delimited, except for a whitelist (PATH, CDPATH, MANPATH). This is
surprising and awkward for other programs to deal with, and there's no way
to get similar behavior for other variables like GOPATH or LD_LIBRARY_PATH.
This commit does the following:
1. Exports all arrays as colon delimited strings, instead of RS.
2. Introduces a notion of "path variable." A path variable will be
"colon-delimited" which means it gets colon-separated in quoted expansion,
and automatically splits on colons. In this commit we only do the exporting
part.
Colons are not escaped in exporting; this is deliberate to support uses
like
`set -x PYTHONPATH "/foo:/bar"`
which ought to work (and already do, we don't want to make a compat break
here).
This reverts commit 3f820f0edf.
While the premise described by @nbuwe is sound in #4505, we are now
apparently relying on this behavior is some places (although
inadvertently as there doesn't seem to be a deliberate acknowledgement
of that anywhere).
Turning off ONLCR causes things like indented multiline commands to not
appear correct at the tty (subsequent lines appear both at column 0 and
again indented).
Per @nbuwe's excellent explanation in #4505, we can save on output
to the tty by maintaining column location after NL by disabling the
ONLCR terminal mode.
Closes#4505.
Adds a new match mode for `string_fuzzy_match_t` that matches against a
case-insensitive subsequence within a string, e.g. `LL` now (partially)
matches against `hello`. This is implemented as a separate mode, given a
lower priority of match than a same-case match (when present).
Note that `fuzzy_match_subsequence_insertions_only` has purposely not
been extended with a case-insensitive version as that would be a)
unlikely to match often, and b) adding a second inefficient fuzzy search
to something that's queried a lot. Perhaps `subsequence_insertions_only`
can simply be changed to be a case-insensitive comparison in the future?
Closes#1196. Affects #3978.
If you're using the old binding that only clears the commandline and
doesn't preserve its contents and start a new line, you can use
```fish
bind \cc "commandline -f cancel; commandline ''"
```
instead.
Closes#4298.
For some weird reason we only used $editor if it wasn't empty, but
then failed to fail if it was.
This will now print an error and use fish, just like if the $EDITOR
value is invalid in any other way.
Fixes#5257.
Came in handy for tracking down the performance regression in #5219. This will
take the output of two (necessarily identical) `fish --profile ...` runs and
produce a third profile log in which all times are the difference between the
first and the second profile provided.
(I'm not sure if build_tools is the right place for it, but I think it's OK?)
This is a wrapper that calls kitty to dynamically provide completions,
as generated by kitty itself, via `kitty + complete setup fish`.

Load fish docs and configuration out of the source and/or build
directories rather from the installed paths when running directly out
of the cmake build directory.
Closes#5255.
Prior to this fix, fish would swallow SIGINT in non-interactive mode. This
meant that scripts could only be Ctrl-C'd if fish was executing an external
command.
Unblock SIGINT in non-interactive mode.
Fixes#5253
Fixes broken macOS build. I'm not sure how the code used to compile
without including `dyld.h` previously, perhaps a different header used
to pull it in?
Retrieves the fully resolved path to the currently executing fish binary
(regardless of PATH). Can be used to ensure that the same fish is
launched again from a script.
`get_executable_path()` moved from fish binary to libfish, also cleaned
up some duplicated (but differing!) definitions of PATH_MAX (which was
used by that function) in the process.
Remove dependency on the Linux compatibility layer's procfs being
installed and mounted when running under FreeBSD by directly querying
the MIB for the path to the running fish executable
(KERN_PROC_PATHNAME). Tested under FreeBSD 11.2-RELEASE.
The hg prompt walks up the directory hierarchy to decide if we are in a
repo subdirectory. Because hg is an external command, it resolves symlinks.
Switch to using pwd -P so hg and fish will have the same view of the hg repo.
Based on comment:

This switches fish to a "virtual" PWD, where it no longer uses getcwd to
discover its PWD but instead synthesizes it based on normalizing cd against
the $PWD variable.
Both pwd and $PWD contain the virtual path. pwd is taught about -P to
return the physical path, and -L the logical path (which is the default).
Fixes#3350
