Ensure that multiple `-k` completions intermixed with one or more non-`-k`
completions are produced in the expected order with the order of all completions
in a single `-k` completion respected, non-`-k` completions correctly sorted and
interspersed, and the results of multiple `-k` completions in the
reverse-intuitive order (with chronologically later completions coming before
chronologically earlier `-k` counterparts), as per #9221.
This particular variant must be executed as a pexpect test since it relies on
the interactive-only `$history` to trigger the recursion. Note that recursion is
possible via other means (e.g. reading/writing a file), the usage of history
here is just one such example.
A false negative while testing locally should be a rare thing, and individual
pexpect tests already take too long in case of a non-match making for a painful
edit-test loop.
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.
This fails on old Ubuntu with:
> touch: invalid date format ‘190112112040.39’
Because we don't actually need the seconds here, we just use minute
resolution. It's fine.
Also use `path mtime`, because that's a portable way to get the mtime.
I forgot `stat` is non-portable. There's no great way to portably get a
machine-readable representation of stat(2) for a file. I don't want to ship our
own lstat(2) wrapper executable just for this test and don't want to fork out to
python or perl for this either - I just wanted to get the tests to pass under
WSL :'(
Anyway, just give up and make it skip just for WSL. If another OS fails this
test in the future, the comments and existing workaround will make it easy to
figure out what the problem is and what needs to be done. We'll cross that
bridge when we get there.
It turns out that not all systems print an unsigned integer as the output of
`stat -c %Y xxx` and the leading `-` can be misinterpreted as a parameter to
`string match`.
There's no guarantee (nor requirement) that the filesystem support pre-epoch
modification dates. If it doesn't, the `test` tests were failing to get the
expected results.
Skip the test if it seems the fs doesn't support pre-epoch timestamps
(determined by pre-epoch mt of `oldest` evaluating to 0 or the unix epoch).
* Replace ";" with "\n" in alias-generated functions
This can let us add a "#" in our aliases to make
them ignore additional arguments.
* Update changelog about aliases that ignore arguments
* Update test for alias.fish
This is now compliant with the aliases that can
ignore arguments.
When fish runs with job control enabled, it transfers ownership of the
tty to a child process, and then reclaims the tty after the process
exits. If job control is disabled then fish does not transfer or reclaim
the tty.
It may happen that the child process creates a pgroup and then transfers
the tty to it. In that case fish will not attempt to reclaim the tty, as
fish did not transfer it. Then when fish reads from stdin it will
receive SIGTTIN instead of data.
Fix this by unconditionally claiming the tty in readline().
Fixes#9181
This errored out *later* because the result was infinite or NaN, but
it didn't actually stop evaluation.
I'm not sure if there is a way to get floating point math to turn an
infinity back into something that doesn't depend on a literal
infinity, but division by zero conceptually isn't a thing we can
support.
There's entire branches of maths dedicated to figuring out what
dividing by "basically zero" means and we don't have to get into it.
This is essentially the inverse of `string pad`.
Where that adds characters to get up to the specified width,
this adds an ellipsis to a string if it goes over a specific maximum width.
The char can be given, but defaults to our ellipsis string.
("…" if the locale can handle it and "..." otherwise)
If the ellipsis string is empty, it just truncates.
For arguments given via argv, it goes line-by-line,
because otherwise length makes no sense.
If "--no-newline" is given, it adds an ellipsis instead and removes all subsequent lines.
Like pad and `length --visible`, it goes by visible width,
skipping recognized escape sequences, as those have no influence on width.
The default target width is the shortest of the given widths that is non-zero.
If the ellipsis is already wider than the target width,
we truncate instead. This is safer overall, so we don't e.g. move into a new line.
This is especially important given our default ellipsis might be width 3.
When selecting items in the pager, only the latest of those items is kept
in the edit history, as so-called transient edit. Each new transient edit
evicts any old transient edit (via undo).
If the pager is closed by a command that performs another transient edit
(like history-token-search-backward) we thus inadvertently undo (= remove)
the token inserted by the pager. Fix this by closing a transient edit
session when closing the pager. Token search will start its own session.
Fixes#9160
This starts two sleep processes and expects them to be killed on
SIGHUP.
Unfortunately, if this ever fails the second run will also fail
because it'll see the old sleep still lying around (because it'll run
for 130 seconds).
So, what we do is:
1. Keep the pids for these specific sleeps
2. Check if any of them are still running (and only fail for them)
3. Kill them from python
Fixes#9152
This checked specifically for "| and" and "a=b" and then just gave the
error without a caret at all.
E.g. for a /tmp/broken.fish that contains
```fish
echo foo
echo foo | and cat
```
This would print:
```
/tmp/broken.fish (line 3): The 'and' command can not be used in a pipeline
warning: Error while reading file /tmp/broken.fish
```
without any indication other than the line number as to the location
of the error.
Now we do
```
/tmp/broken.fish (line 3): The 'and' command can not be used in a pipeline
echo foo | and cat
^~^
warning: Error while reading file /tmp/broken.fish
```
Another nice one:
```
fish --no-config -c 'echo notprinted; echo foo; a=b'
```
failed to give the error message!
(Note: Is it really a "warning" if we failed to read the one file we
wer told to?)
We should check if we should either centralize these error messages
completely, or always pass them and remove this "code" system, because
it's only used in some cases.
This skipped printing a "^" line if the start or length of the error
was longer than the source.
That seems like the correc thing at first glance, however it means
that the caret line isn't skipped *if the file goes on*.
So, for example
```fish
echo "$abc["
```
by itself, in a file or via `fish -c`, would not print an error, but
```fish
echo "$abc["
true
```
would. That's not a great way to print errors.
So instead we just.. imagine the start was at most at the end.
The underlying issue why `echo "$abc["` causes this is that `wcstol`
didn't move the end pointer for the index value (because there is no
number there). I'd fix this, but apparently some of
our recursive variable calls absolutely rely on this position value.
