Seems like size_t is unnecessarily large as well, as elsewhere
in the code we are clamping down to uint32_t / source_offset_t.
This makes tok_t more like 16 bytes. More cleanup seems desirable,
this is not very well hamrnoized across our code base.
Instead of 7a80ad74f, which adds ifdeffery, we simply drop the
variables we don't care about. This leaves two presumably
glibc-specific variables, but drops 5 variables like LC_MONETARY, so
it's overall a win.
This reverts commit 7a80ad74f4379b5960e723d124069f190fa4e877.
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 command like "printf nonewline | sed s/x/y/" does not print a
concluding newline, whereas "printf nnl | string replace x y" does.
This is an edge case -- usually the user input does have a newline at
the end -- but it seems still better for this command to just forward
the user's data.
Teach most string subcommands to check if stdin is missing the trailing
newline, and stop adding one in that case.
This does not apply when input is read from commandline arguments.
* Most subcommands stop adding the final newline, because they don't
really care about newlines, so besides their normal processing,
they just want to preserve user input. They are:
* string collect
* string escape/unescape
* string join¹
* string lower/upper
* string pad
* string replace
* string repeat
* string sub
* string trim
* string match keeps adding the newline, following "grep". Additionally,
for string match --regex, it's important to output capture groups
separated by newlines, resulting in multiple output lines for an
input line. So it is not obvious where to leave out the newline.
* string split/split0 keep adding the newline for the same reason --
they are meant to output multiple elements for a single input line.
¹) string join0 is not changed because it already printed a trailing
zero byte instead of the trailing newline. This is consistent
with other tools like "find -print0".
Closes#3847
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".
