In particular, this fixes the case
ctrl-r foo ctrl-r
where foo substring-matches no more than one page's worth of results.
The second attempt will fall back to subsequence matching which is wrong.
In case a terminal resize[1] causes us
to repaint a multi-line prompt that changes width like
function fish_prompt
for i in 1 2 3
random choice 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaa' 'bbbbbbbbbbb'
end
end
we add a clr_eol after each line[2] , to make sure
that a "b" line does not have leftover "a" letters
(80aaae5b7 (Clear to end of each line in left prompt, 2020-10-25)).
Unfortunately, if a prompt line takes up all the columns, clr_eol will
wrongly clear the last column. Reproduce with
function fish_prompt
string repeat $COLUMNS -
echo "$PWD> "
end
and observe that the last "-" is missing.
Previous (reverted) attempt d3ceba107 (Clear to eol before outputting line
in multi-line prompt, 2021-05-17) found the right fix but had an off-by-one
error which reintroduced the leftover "a" letters in the "random choice"
prompt above.
Given prompt string "aa\nbb\ncc", it wrongly printed
clr_eol "aa" clr_eol "\nbb" "\ncc"
Observe that the first line is cleared twice, while the second line is
never cleared. Fix that.
[1]: or an async "commandline -f repaint" triggered by a uvar change /
async prompt update
[2]: except after the last line where we probably already emit clr_eol
elsewhere..
Alternative fix: emit both clr_eol and clr_bol *before* drawing the current
line. However, if fish and the terminal disagree on character width, that
approach might erase too much.
Closes#8164
I guess it's nice to know that these two are the same but that info is not
needed here, it just adds confusion. The user must have pressed ctrl-j if
we get here, so echo that back.
See the parent commit.
This is just too confusing; \b sounds like it would map backspace but it's
actually just ctrl-h. Backspace is a different key ("bind backspace"),
so let's move away from \b.
Reproduce by typing ctrl-h in fish_key_reader, or, for even more confusion,
use a terminal like tmux and type ctrl-backspace which also sends ctrl-h.
I've thought about changing \b (and its aliases like \ch and \x08) to mean
backspace but that seems like unnecessary breakage, since they all already
mean ctrl-h, and can usually be mapped independent of backspace.
See the discussion in #10738
Make fish-printf no longer depend on the widestring crate, as other clients
won't use it; instead this is an optional feature.
Make format strings a generic type, so that both narrow and wide strings can
serve. This removes a lot of the complexity around converting from narrow to
wide.
Add a README.md to this crate.
This gave a weird error when you did e.g. `math Foo / 6`:
"Missing Operator" and only the "F" marked.
Adding an operator here anywhere won't help, so calling this an
"Unknown function" is closer to the truth. We also get nicer markings
because we know the extent of the identifier.
Fix 7308dbc7a (fish_indent: Prevent overwriting file with identical content,
2024-07-21) in a different way by passing O_TRUNC again.
If we don't want regressions we could use code review.
When `manpath` prints a symlink to a directory, `/usr/libexec/makewhatis`
ignores the entire directory:
```
$ /usr/libexec/makewhatis -o /tmp/whatis \
(/usr/bin/manpath | string split :)
makewhatis: /Users/wiggles/.nix-profile/share/man: Not a directory
```
This means that the built-in `man` completions will not index any commands in
these directories.
If we pass the directories to `readlink -f` first, `makewhatis` correctly
indexes the `man` pages.
```
$ /usr/libexec/makewhatis -o /tmp/whatis \
(/usr/bin/manpath | string split : | xargs readlink -f)
```
We used deque in C++ because this vector may be large, and so it avoids
repeated re-allocations. But VecDeque is different in Rust - it's contiguous -
so there's no benefit. Just use Vec.
For implementation reasons, we special-case cd in several ways
1. it gets different completions (handle_as_special_cd)
2. when highlighting, we honor CDPATH
3. we discard autosuggestions from history that don't have valid path arguments
There are some third-party tools like zoxide that redefine cd ("function cd
--wraps ...; ...; end"). We can't support this in general but let's try to
make an effort.
zoxide tries to be a superset of cd, so special case 1 is still
valid but 2 and 3 are not, because zoxide accepts some paths
that cd doesn't accept.
Let's add a hack to detect when "cd" actually means something else by checking
if there is any --wraps argument.
A cleaner solution is definitely possible but more effort.
Closes#10719
fish adds ~/.local/share/fish/man to its MANPATH for builtins etc. But pages
like fish-doc are unambiguous so it seems like they should be accessible
from outside fish by default.
Closes#10711
In some cases we add the wildcard twice.
$ fish -c '../jj; complete -C"ls cli/*/conf/tem"'
cli/*/*/config/templates.toml
Fix that. Test in the next commit.
There seems to be another bug in 3.7.1 where we fail to apply this completion
to the command line. This appears fixed. (FWIW we might want to revert
the quoting change in completion_apply_to_command_line(), maybe that one
accidentally fix this).
Fixes#10703
The HashMap is used to generate the __fish_describe_command integration
completions. Given the nature of the allocations and the numbers that we use, a
BTreeMap would theoretically perform better. Benchmarks show a 2-9%
improvement in completion times consistently in favor of BTreeMap.
Warnings were appearing under GCC 13.2
(void) alone is insufficient under modern compilers, workaround with logical
negation taken from GCC bug tracker.
