Commit 3b30d92b6 (Commit transient edit when closing pager, 2022-08-31)
inadvertently introduced two regressions to history search:
1. It made Escape keeps the selected history entry,
instead of restoring the commandline before history search.
2. It made history search commands add undo entries.
Fix both of this issues.
Inadvertently broken in a2d816710f,
this made `cd .` no longer offer `cd ../` (same for general file completions
like `ls .`, which only offers dotfiles)
This means cleaning out old universal variables is now just:
```fish
abbr --erase (abbr --list)
```
which makes upgrading much easier.
Note that this erases the currently defined variable and/or any
universal. It doesn't stop at the former because that makes it *easy*
to remove the universals (no running `abbr --erase` twice), and it
doesn't care about globals because, well, they would be gone on
restart anyway.
Fixes#9468.
This now means `abbr --add` has two modes:
```fish
abbr --add name --function foo --regex regex
```
```fish
abbr --add name --regex regex replacement
```
This is because `--function` was seen to be confusing as a boolean flag.
Unfortunately print_hints was true *by default* - so for all builtins
that didn't pass it it would now be false instead.
This resulted in the trailer missing, which includes the line number
and context. So if you ran a script that includes `bind -M` the error
message would now just be "bind: -M: option requires an argument",
with no indication as to where.
This reverts commit 8a50d47a46.
This would print
```
abbr -a -- dotdot --regex ^\\.\\.+\$ --function multicd
```
which expands "dotdot" to "--regex ^\\.\\.+\$...".
Instead, we move the name to right before the replacement, and move
the `--` before that:
```
abbr -a --regex ^\\.\\.+\$ --function -- dotdot multicd
```
It might be possible to improve that, but this at least round-trips.
This renames abbreviation triggers from `--trigger-on entry` and
`--trigger-on exec` to `--on-space` and `--on-enter`. These names are less
precise, as abbreviations trigger on any character that terminates a word
or any key binding that triggers exec, but they're also more human friendly
and that's a better tradeoff.
This adds support for the `--function` option of abbreviations, so that the
expansion of an abbreviation may be generated dynamically via a fish
function.
Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.
Re-implement abbreviations using a builtin, managing them internally.
Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.
Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.
We have had multiple crashes for relative CDPATH entries. Commit 5e274066e
(Always return absolute path in path_get_cdpath, 2019-10-17) tried to fix
all of them but it failed to do justice to its title. Let's fix this to
actually return absolute paths, always. Take care to to normalize the path
because it is used for autosuggestions. The normalization is mostly relevant
for CDPATH=. (the default) but it doesn't hurt others.
Closes#9407
Inside a comment we offer plain file completions (or command completions if
the comment is in command position). However these completions are broken
because they don't consider any of the surrounding characters. For example
with a command line
echo # comment
^ cursor
we suggest file completions and insert them as
echo # comsomefile ment
Providing completions inside comments does not seem useful and it can be
misleading. Let's remove the completions; this should communicate better that
we are in a free-form comment that's not subject to fish syntax.
Closes#9320
This fixes#9321
IEEE Std 1003.1-2017 Issue 6 added optional error condition

Like the pexpect-based pager compeltions test `complete-group-order.py`, but for
the `complete` builtin. Verifies the same sort/dedup rules that apply to the
pager are also applied to the output of `complete` and asserts the sort behavior
for multiple `complete -k` calls for the same command and with the same (or with
both passing) preconditions.
This addresses a long-standing TODO where `complete -C` output isn't
deduplicated.
With this patch, the same deduplication and sort procedure that is run on actual
pager completions is also executed for `complete -C` completions (with a `-C`
payload specified).
This makes it possible to use `complete -C` to test what completions will
actually be generated by the completions pager instead of it displaying
something completely divorced from reality, improving the productivity of fish
completions developers.
Note that completions that wouldn't be shown in the pager are also omitted from
the results, e.g. `test/buildroot/` and `test/fish_expand_test/` are omitted
from the check matches in `checks/complete_directories.fish` because even if
they were generated, the pager wouldn't have shown them. This again makes
reasoning about and debugging completions much easier and more sane.
Fixes ommitted newline char shown after complete -n'(foo)'
Also axes the 'contains syntax errors' line before the error.
Update tests
before
> complete -n'(foo)'
complete: Condition '(foo)' contained a syntax error
complete: Command substitutions not allowed⏎
after
> complete -n'(foo)'
complete: -n '(foo)': command substitutions not allowed here
Up to now, in normal locales \x was essentially the same as \X, except
that it errored if given a value > 0x7f.
That's kind of annoying and useless.
A subtle change is that `\xHH` now represents the character (if any)
encoded by the byte value "HH", so even for values <= 0x7f if that's
not the same as the ASCII value we would diverge.
I do not believe anyone has ever run fish on a system where that
distinction matters. It isn't a thing for UTF-8, it isn't a thing for
ASCII, it isn't a thing for UTF-16, it isn't a thing for any extended
ASCII scheme - ISO8859-X, it isn't a thing for SHIFT-JIS.
I am reasonably certain we are making that same assumption in other
places.
Fixes#1352
We forgot to decode (i.e. turn into nice wchar_t codepoints)
"byte_literal" escape sequences. This meant that e.g.
```fish
string match ö \Xc3\Xb6
math 5 \X2b 5
```
didn't work, but `math 5 \x2b 5` did, and would print the wonderful
error:
```
math: Error: Missing operator
'5 + 5'
^
```
So, instead, we decode eagerly.
Prior to 1811a2d, the return value for negative return codes was UB and I'd
witnessed both expected cases like -256 mapping to a $status of 0 and unexpected
cases like a return value of -1 mapping to a $status of 0. As such, this doesn't
test just one fixed return value but the entire range from negative multiples of
256 all the way down (rather, up!) to -1.
...for improved cross-platform support.
Following up on the work in c90ac7b. There was one more test that had mktemp in
the littlecheck "shebang" and this also removes a now-unnecessary `env` prefix.
All usages of `mktemp` must go through the (fish-only) `mktemp` test function
that abstracts over the differences across multiple platforms/flavors.
Tests can be easily run individually via `ninja -C build test_xxx` and there
isn't a good reason to randomly manually override $HOME and $XDG_CONFIG_HOME for
a test here and a test there.
If it's absolutely necessary, littlecheck.py should be extended to support a
`%temp` variable initialized to a temporary directory and that can be used
instead of calling out to the platform-provided `mktemp` via a subshell.
For unknown reasons, the i686 launchpad builders fail on this date,
but apparently not the others.
Let's just remove it, we've tested dates older than the epoch, this is
slightly redundant.
As discussed in #9221, a bug in the autocomplete that was fixed in 66391922
caused completions to be incorrectly suppressed. The dropped test/check was
inadvertently relying on the buggy behavior and expected a git invocation to
generate no completions but there are, in fact, completions now that the bug has
been resolved.
cc @faho: I'm not sure if you want to replace this with a different check that
actually doesn't yield any completions or if you're happy with it just being
dropped.
