The builtin history delete call has some code that removes a leading and
trailing quote from its arguments. This code dates back to ec34f2527a,
when the builtin was introduced. It seems wrong and tests pass
without it. Let's bravely remove it.
Use the remaining_to_disclose count to determine if all completions
are shown (allows consistent behavior between short and long completion
lists).
Closes#8485
Commit e40eba358 (Treat text following quoted command substitution
as quoted) made parse_util_locate_cmdsubst_range() aware of quoted
command substitutions, by skipping surrounding text via quote_end().
However, it was not quite right. We fail to properly parse
two consecutive command substitutions in the same string,
because we don't maintain the quoting context across calls to
parse_util_locate_cmdsubst_range(). Let's track that bit in a
parameter. This allows us to get rid of the quote_end() hack.
Also apply this to the other place where we call
parse_util_locate_cmdsubst_range() in a loop (highlighting).
Fixes#8500
This fixes a regression about where we report errors:
echo error(here
old: ^
fixed: ^
Commit 0c22f67bd (Remove the old parser bits, 2020-07-02) removed
uses of "error_offset_within_token" so we always report errors at
token start. Add it back, hopefully restoring the 3.1.2 behavior.
Note that for cases like
echo "$("
we report "unbalanced quotes" because we treat the $( as double
quote. Giving a better error seems hard because of the ambguity -
we don't know if quote is meant to be inside or outside the command
substitution.
If you make a script called `foo` somewhere in $PATH, and did not give
it a shebang, this would end up calling
sh foo
instead of
sh /usr/bin/foo
which might not match up.
Especially if the path is e.g. `--version` or `-` that would end up
being misinterpreted *by sh*.
So instead we simply pass the actual_cmd to sh, because we need it
anyway to get it to fail to execute before.
I think the auto-all-the-things here was a making this a little
hard to follow, so replace these things that will be used in printf
with what they really are. And change the * lengths to ints.
should clear up the alerts.
When the completion pager fills up all lines of the screen, we subtract
from the pager size the number of lines occupied by the prompt +
command line buffer (typically 1), so the command line is always
visible. However, we only subtract the number of lines *before* the
cursor, so on some multiline commandlines we draw a pager that is
too large for our screen, clobbering the commandline rendering.
Fix this by counting all lines.

As seen in
https://stackoverflow.com/questions/70139844/how-to-execute-custom-fish-scripts-in-custom-path-folder,
making a shebang like
#!usr/bin/fish
won't work, and will error with the default "file does not exist"
error *pointing to the file, not the interpreter*.
Detect that interpreter properly.
We might want to make this an even more specific error, but now it
says
```
exec: Failed to execute process '/home/alfa/.local/bin/borken.fish': The file specified the interpreter 'usr/bin/fish', which is not an executable command.
```
Which is okay.
A completion entry like «complete -a '\\~'» results in completions
that insert \~ into the command line. However we usually want to
insert ~, but there is no way to do that.
There are a couple of longstanding issues about completion escaping
[1]. Until we fix those in a general way, fix the common case by
never escaping tildes when applying custom completions to the command
line. This is a hack but will probably work out fine because we don't
expect literal tildes in arguments.
The tilde is included in completions for cdh, or
__fish_complete_suffix, which simply forwards results from "complete
-C". Revert a workaround to cdh that expanded ~, because we can now
render that without escaping.
Closes#4570, #8441

[1]: https://github.com/fish-shell/fish-shell/pull/8441#discussion_r748803338
A «complete -C '~/fish-shell/build/fish '» fails to load custom
completions because we do not expand the ~, so
complete_param_for_command() thinks that this command is invalid.
Expand command tokens before loading custom completions.
Fixes#8442
Currently,
set -q --unpath PATH
simply ignores the "--unpath" bit (and same for "--path").
This changes it, so just like exportedness you can check pathness.
* fish_key_reader: Simplify default output
It now only prints the bind statement. Timing information and such is
relegated to a separate "verbose" mode.
* Adjust fish_key_reader docs
* Adjust tests
What this did was
1. Find directory
2. Turn name into wcstring and return it
3. Turn name back into string for some operations
Instead, let's unglue the wcstringing from this, return the narrow
string and then widen it when we need.
This didn't even mention that it was a script file, it was just
filename: File not found
Which would be rather confusing if e.g. someone forgot that
`--profile` requires an argument.
This finds the first broken component, to help people figure out where
they misspelt something.
E.g.
```
echo foo >/usr/lob/systemd/system/machines.target.wants/var-lib-machines.mount
```
will now show:
```
warning: Path '/usr/lob' does not exist
```
which would help with seeing that it should be "/usr/lib".
Commit fe63c8ad3 (Shadow/override iswdigit instead of changing it at
individual call sites, 2021-10-04) added our own implementation of
iswdigit() to common.h. The "include-what-you-use" rule means that
files that use iswdigit() should now include common.h. Do that.
A variable may be broken across multiple lines with a backslash, for
example:
> echo $FISH_\
VERSION
Teach syntax highlighting about this line breaking. Fixes#8444
check_global_scope_exists is meant to warn if the user creates a
universal variable shadowing a global. In practice it always returned
success (though it may print an error). Remove its return value and
clean up the call sites. Also rename it to
`warn_if_uvar_shadows_global`. No functional change in this commit.
On a commandline like "ls arg" (cursor at end) we do not expand
abbrevations on enter. OTOH, on "ls " we do expand. This can be
frustrating because it means that the two obvious ways to suppress
abbrevation expansion (C-Space or post-expansion C-Z) cannot be used to
suppress expansion of a command without arguments. (One workaround is
"ls #".)
Only expand-on-execute if the cursor is at the command name (no space
in between).
This is a strict improvement for realistic scenarios, because if there
is a space, the user has already expressed the intent to not expand
the abbreviation. (I hope no one is using recursive abbreviations.)
Closes#8423
This allows to disable autosuggestions in config or with
fish -C 'set -g fish_autosuggestion_enabled 0'
instead of only in existing interactive sessions.
I'm not sure if passing the env var table is actually necessary here,
since we already have a reader.
This allows rebinding escape in the user list without breaking e.g.
arrow keys (which send escape and then `[A` and similar, so escape is
a prefix of them).
Fixes#8428.
+ No functional change here, just renames and #include changes.
+ CMake can't have slashes in the target names. I'm suspciious of
that weird machinery for test, but I made it work.
+ A couple of builtins did not include their own headers, that
is no longer the case.
Very slight performance increase (1% when parsing *all .fish scripts
in fish-shell*), but this removes a useless variable and some
.c_str()inging.
Theoretically it should also remove some wcslen() calls, but those
seem to be optimized out?
This fixes printing octal and hex values that are negative or larger
than UINT_MAX.
Negative values get a leading -, like:
> math --base hex -10
-0xa
Fixes#8417.
