When I run a command with leading space, it is not added to the on-disk
history. However we still call History::save(). After 25 of such calls,
we rewrite the history file (even though nothing was written by us).
This is annoying when diagnosing #10300 where the history of the current
shell (but not other shells) is broken; because the history rewrite will
make the problem go away. Let's not save in this case, to make it easier to
run commands to inspect the state of the history file.
Commit 4e79ec5f tried to restore the static PCRE2 build after the update to the
pcre2 crate, but it set an environment variable at configure time, not build
time.
Properly set the environment variable at build time.
Given a history like
- cmd: echo OLD
when: 1726157160
\x00\x00\x00- cmd: echo leading NUL bytes
when: 1726157160
- cmd: echo NEW
when: 1726157223
offset_of_next_item() happily records 3 items even though the second item
is corrupted.
decode_item() fails which makes the caller stop loading any older items --
we got knee capped.
Avoid this horrible failure mode by skipping over these items already in
offset computation. For now we still lose the corrupted item itself.
In future we should probably try to delete the NUL bytes or avoid the
corruption in the first place.
See #10300 and others.
This should make the sort have a strict weak ordering, which rust
requires since 1.81 (or it will panic).
Note: This changes the order, but that's *fine* since the current
order is random weirdness anyway.
Fixes#10763
This was overly smart and tried to not show you e.g. global variables
unless you were setting without scope or explicitly global.
That is annoying when you do
`set -g fish_col<TAB>`
and don't get colors because they're universal, but you could
overwrite them.
We *could* elide e.g. local variables if we're setting a global, but I
can see someone wanting to set a universal variable on basis of a
global ("save this"), so I would rather not try to find the very
specific cases where this works.
1. Leave the indentation
2. Leave the "NAME" header - without the first line would be
unindented
3. Leave the "SYNOPSIS" header
We use $MANPAGER here, so it should be formatted like a manpage.
The alternative is to write special docs for this use-case, which
would be shorter and point towards the full man page.
Fixes#10625
They are already presented in normal mode, and I presume were forgotten to be
added in visual mode
I don't add it to ./CHANGELOG.rst because it's a minor change that can be
considered as a bug fix
The recent update to the rust-pcre2 crate lost the property where a static
PCRE2 build could be enabled with a Cargo feature. This means that static
PCRE2 builds can no longer be forced.
Switch to setting the "PCRE2_SYS_STATIC" variable again, which is how the
official rust-pcre2 crate expects to work.
Commit c921c124e (docs: use canonical key names in :kbd: tags, 2024-04-13)
removed the box highlighting from elements like :kbd:`ctrl-c`.
This is because Sphinx for some reason converts this into
<kbd>
<kbd>ctrl</kbd>
-
<kbd>c</kbd>
</kbd>
which results in duplicate boxes.
(See https://github.com/sphinx-doc/sphinx/issues/7530)
Our current style looks a bit ugly (it's
definitely worse than github's rendering at
https://github.com/fish-shell/fish-shell/blob/master/CHANGELOG.rst).
Let's restore the old style but make sure to only apply it only to the
outermost kbd element.
While at it, use the same monospace font as for inline code.
Commit b00899179 (Don't indent multi-line quoted strings; do indent inside
(), 2024-04-28) made parse_util_compute_indents() crash on `echo "$()"'x`.
After recursively indenting the command substitution, we indent the "'x
suffix. We skip the quoted part by setting "done=2". Later we wrongly
index "self.indents[done..range.start+offset+1]" (= "self.indents[2..1]").
Fix this by making sure that "start >= done", thus not setting any indents
for the quoted suffix. There is no need to do so; only the first character
in each line needs an indent.
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.
