When we discard output because there's been too much, we print a
warning, but subsequent uses of the same buffer still discard.
Now we explicitly reset the flag, so we warn once and everything works
normal after.
Fixes#5267.
For things like
source $undefined
or
source (nooutput)
it was quite annoying that it read from tty.
Instead we now require a "-" as the filename to read from the tty.
This does not apply to reading from stdin if it's redirected, so
something | source
still works.
Fixes#2633.
This adds flags --path and --unpath to builtin set, analogous to
--export and --unexport. These flags change whether a variable is
marked as a path variable.
Universal variables cannot yet be path variables.
This switches quoted expansion like "$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?)
