It still performs the assignment even if the command substitution
returned unsuccessfully - `set foo (echo bar; false)` returns 1 but
sets $foo to bar.
Also use `type -p` instead of `which`.

Another change related to issue #3985. I forgot to includes this in my
previous two changes related to to consistently returning status 121
when any command, not just `string`, is handed invalid args.
This primarily replaces "STATUS_BUILTIN_OK" with "STATUS_CMD_OK" and
"STATUS_BUILTIN_ERROR" with "STATUS_CMD_ERROR". That is because we want
to make it clear these status codes are applicable to fish functions as
well as builtins. Future changes will make it easier to use these
symbols and values in functions.
Per discussion in PR#3998 to review adding a `--filter` flag to `string
replace` rename the same flag in the `string match` subcommand to avoid
confusion about the meaning of the flag.
Discussion in issue #3295 resulted in a decisions to rename the
functions --metadata flag to --details.
This also fixes a bug in the definition of the short flags for the
`functions` command. The `-e` flag does not take an argument and
therefore should not be defined as `e:`. Notice that the long form,
`--erase`, specifies `no_argument`. This discrepency happened to work
due to a quirk of how the flag parsing loop was written.
This is the first step in addressing issue #3965. It renames some of the
functions involved in validating variable and function names to clarify
their purpose. It also augments the documentation to make the rules for
such identifiers clearly documented.
- Error out if anything that is not a PID is given
- Otherwise background all matching existing jobs, even if not all
PIDs exist (but print a message for the non-existing ones)
Fixes#3909.
This puts a hard upper bound of 10 MiB on the amount of data that read
will consume. This is to avoid having the shell consume an unreasonable
amount of memory, possibly causing the system to enter a OOM condition,
if the user does something non-sensical.
Fixes#3712
This implements a way to use the `functions` command to perform
introspection to learn about the characteristics of a function. Such as
where it came from.
Fixes#3295
If the kernel reports a size of zero for the rows or columns (i.e., what
`stty -a` reports) fall back to the `COLUMNS` and `LINES` variables. If
the resulting values are not reasonable fallback to using 80x24.
Fixes#3740
* Added new function for the default prompt mode
Now fish mode prompt will call fish_default_mode_prompt, this will solve #3641
* Added function description
* Change wording for documentation about default mode prompt
* Finish changes requested in code review
Another dev pointed out my previous attempt to resolve issue #3612 did
not do a good job of clarifying the matter. Hopefully this change is
better at explaining why autoloading is not applicable to aliases.
* Add italics and dim modifier to set_color
* update documentation for set_color
* add reverse mode to set_color
* Use standout mode as fallback for reverse mode
* Apply patch from @Darkshadow2 adding additional modes
Trailing whitespace on a `\fish` command was causing this build failure:
/private/var/folders/T/fish_doc_build_3RT8yS/random.doxygen:44:
warning: found </pre> tag without matching <pre>
This implements a standard function and bindings for editing the command
line in an external editor. This feature has been requested multiple
times in the past year with various solutions cut and pasted into those
issues. This change combines the best aspects of those solutions.
Fixes#1215
