For reasons unclear to me, fish enables bold mode unconditionally if
the background is set.
However, this called a background "set" if it wasn't exactly the
"normal" color, whereas set_color --print-colors would set a color
of *none*.
We have three special non-color colors:
- "normal"
- "reset"
- "none"
All of these specify some form of absence of background color, so all
of them should be checked.

* Rewrite the real file if history file is a symlink
When the history file is a symbolic link, `fish` used to overwrite
the link with a real file whenever it saved history. This makes
it follow the symlink and overwrite the real file instead.
The same issue was fixed for the `fish_variables` file in 622f2868e
from https://github.com/fish-shell/fish-shell/pull/7728.
This makes `fish_history` behave in the same way. The implementation
is nearly identical.
Since the tests for the two issues are so similar, I combined them
together and slightly expanded the older test.
This also addresses https://github.com/fish-shell/fish-shell/issues/7553.
* Add user-facing error when history renaming fails
Currently, when history file renaming fails, no message is shown to the
user. This happens, for instance, if the history file is a symlink
pointing to another filesystem.
This copies code (with a bit of variation, after reviewer comments) from
589eb34571/src/env_universal_common.cpp (L486-L491)
into `history.cpp`, so that a message is shown to the user.
* fixup! Rewrite the real file if history file is a symlink
This reverts commit e240d81ff8 and
introduces a more compatible method of finding newly added fish scripts
to syntax check.
`find -newer` is the original and is supported by everything under the
sun (including FreeBSD, NetBSD, Solaris, OpenIndiana, macOS 10.10, WSL,
and more), and if not, the tests will succeed anyway. `find -mnewer` was
added later around the time `find -cnewer` and co (which checks the
creation date rather than the modification date) was introduced, but
apparently the GNU version of coreutils never introduced the `-mnewer`
alias for `-newer`.
Yes, this is hacky and yes it would be ideal if the build system is the
one that picked which tests to run rather than the test itself picking.
But let's not pretend that our tests are idealogically ideal or pure
right now and until we fix the mess that is our CMake test integration
(e.g. use ctest and configure each test to be run separately with
configurable payloads, etc) eight seconds is still eight seconds, and
again, the CI isn't affected.
My find (GNU findutils 4.8.0) prints
> find: unknown predicate `-mnewer'
So we would have to test for support.
Also this is *super* hacky - tests aren't supposed to keep files
around, this is something you would do in the build system.
This reverts commit ddd0e28b4f.
Only check fish files that have been modified since the last time they
were checked. (This continues with the assumption that we are testing
for broken /usr/share fish scripts and not breakage of the fish parser,
which is covered by all the other tests.)
This saves 8 seconds on an NVMe disk under WSL. Won't affect integrity
of CI runs, which start with a blank slate each time.
Apparently the grep on FreeBSD doesn't do \s or \t. Since we're
looking for an actual tab, just give it an actual tab.
See https://builds.sr.ht/~faho/job/448496.
This `set -e` had a cartesian product that caused it to remove the
indexes separately, so the later indexes were off - removing the first
and then the second ends up removing the first and then the
old-*third* which is now the second.
Just quote the expansion so it runs in one go.
Fixes#7776
NetBSD's sleep quits when foregrounded sometimes. I'm not entirely
sure *why*, but this is reproducible with the default /bin/sh, so it's
not our fault.
Because this fails our tests, go back to using cat *there*, because we
can't use it on macOS - 4c9d01cab0.
The user may write for example:
echo foo >&5
and fish would try to output to file descriptor 5, within the fish process
itself. This has unpredictable effects and isn't useful. Make this an
error.
Note that the reverse is "allowed" but ignored:
echo foo 5>&1
this conceptually dup2s stdout to fd 5, but since no builtin writes to fd
5 we ignore it.
fish_indent used to increment the indentation level whenever we saw an escaped
newline. This broke because of recent changes to parse_util_compute_indents().
Since parse_util_compute_indents() function already indents continuations
there is not much to do for fish_indent - we can simply query the indentation
level of the newline. Reshuffle the code since we need to pass the offset
of the newline. Maybe this can even be simplified further.
Fixes#7720
This fails on FreeBSD on sr.ht and NetBSD on my own VM, but it works manually.
It also fails on macOS but I have no way to confirm.
I think it might be a problem in pexpect's platform support?
Either way, the test is valuable so just skip it there and solve it later.
Otherwise this would look weird if you had, say, a tab in there.
See #7716.
(note that this doesn't handle e.g. zero-width-joiners, because those
aren't currently escaped. we might want to add an escape mode for
unprintable characters, but for combining codepoints that's tricky!)
After commit 6dd6a57c60, 3 remaining
builtins were affected by uint8_t overflow: `exit`, `return`, and
`functions --query`.
This commit:
- Moves the overflow check from `builtin_set_query` to `builtin_run`.
- Removes a conflicting int -> uint8_t conversion in `builtin_return`.
- Adds tests for the 3 remaining affected builtins.
- Simplifies the wording for the documentation for `set --query`.
- Does not change documentation for `functions --query`, because it does
not state the exit code in its API.
- Updates the CHANGELOG to reflect the change to all builtins.
This was lost in
6bdbe732e40c2e325aa15fcf0f28ad0dedb3a551..c7160d7cb4970c2a03df34547f357721cb5e88db.
Note that we only print a term-support flog message for now, the
warning seems a bit much.
Fixes#7709.
Prior to this fix, if stdin were explicitly closed, then builtins would
silently fail. For example:
count <&-
would just fail with status 1. Remove this limitation and allow each
builtin to handle a closed stdin how it sees fit.
builtin_set_query returns the number of missing variables. Because the
return value passed to the shell is an 8-bit unsigned integer, if the
number of missing variables is a multiple of 256, it would overflow to 0.
This commit saturates the return value at 255 if there are more than 255
missing variables.
Prior to this change, the checks/git.fish test would fail if run from a
git interactive rebase (such as via `git rebase -i --exec 'ninja test'`),
because git itself would inject stuff into the environment. Teach the git
test how to clean up its environment first before running.
This needs to be rewritten, I'm pretty sure we have like 6 of these
kinds of ad-hoc "is this quoted" things lying around.
But for now, at least don't just check if the *previous* character was
a backslash.
Fixes#7685.
This goes to a separate file because that makes option parsing easier
and allows profiling both at the same time.
The "normal" profile now contains only the profile data of the actual
run, which is much more useful - you can now profile a function by
running
fish -C 'source /path/to/thing' --profile /tmp/thefunction.prof -c 'thefunction'
and won't need to filter out extraneous information.
Expansion parses slices like "$PATH[1..2]", but so does "set" when assigning
"set PATH[1..2] . .". Commit be06f842a ("Allow to omit indices in index
range expansions") forgot the latter.
This makes the fish_git_prompt variable handlers kick in, meaning we
see the informative chars.
The big question here is what happens if there's a non-UTF-8 locale in
the test.
Theoretically we set LC_CTYPE, but.....
This used to print a literal DEL character in the output for `bind`,
which wouldn't actually show up and made it hard to figure out what
the key was.
So we just escape it back to how we actually used it - `\x7f`.
Fixes#7631.
A weird interaction between grouped short options and our weird option
parsing that puts unknown options back:
```
echo "-n foo"
```
would see the `-n`, turn off printing newlines, interpret the " " as
another grouped short option, see that there is no short option for
space and put the entire token back on the arguments pile.
So it would print "-n foo" *without a newline*.
Fix this by keeping an old state of the options around and reverting
it when putting options back.
The alternative is *probably* to forbid the " " short option in
wgetopt, then check if an option group contains it and error out, but
this should only really be a problem in `echo` because that is,
AFAICT, the only thing that puts the options back.
Fixes#7614
This adds a test to ensure that if a long running background process is
launched from a command substitution, that process does not cause the
cmdsub to hang. That could easily happen if we just wait for the pipe to
close; this is verifying that we are also checking for the job to complete.
Prior to this change, `fish_private_mode` worked by just suppressing
history outright. With this change, `fish_private_mode` can be toggled on
and off. Commands entered while `fish_private_mode` is set are stored but
in memory only; they are not written to disk.
Fixes#7590Fixes#7589
Don't go into implicit interactive mode without ever executing
anything - not even `exit` or reacting to ctrl-d. That just renders
the shell useless and unquittable.
It was always a bit ridiculous that argparse required `X-longflag` if
that "X" short flag was never actually used anywhere.
Since the short letter is for getopt's benefit, we can hack around
this with our old friend: Unicode Private Use Areas.
We have a counter, starting at 0xE000 and going to 0xF8FF, that counts
up for all options that don't have a short flag and provides one. This
gives us up to 6400 long-only options.
6.4K should be enough for everybody.
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.
With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.
Fixes#7222.
