This changes all of the builtins to behave like `string` to return
STATUS_INVALID_ARGS (121) if the args passed to the command don't make
sense. Also change several of the builtins to use the existing symbols
(e.g., STATUS_CMD_OK and STATUS_CMD_ERROR) rather than hardcoded "0"
and "1" for consistency and to make it easier to find such values in
the future.

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.
The bind mode names can be, and are, used in the construction of fish
variable names. So don't allow users to use names that are not legal as
a variable name. This should not break anything since, AFAICT, no
existing fish scripts, including those provided by Oh-My-Fish and
Fisherman define bind modes that would not be legal with this change.
Fixes#3965
This is to fix tests on Travis, since that stores the commit message in an environment variable.
`env | grep MANPATH` of course picks it up and generates unwanted output.
Yes.
Fixes invalid character in variable name $fish_cursor_replace-one (used by fish_vi_cursor[_handle]) by renaming bind mode 'replace-one' to 'replace_one'.
Reviewing a PR for a completion script caused me to look at the
implementation for the `__fish_complete_directories` function. Which in
turn lead me to create this change to improve its implementation and add
unit tests for the function.
- 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.
If the first word of the alias body ends with a semicolon we need to
strip that character, and otherwise escape the extracted command, to
ensure the subsequent function definition is valid.
Fixes#3860
The previous change neglected to consider that numbers too large for the
long long datatype will result in calling strerror(ERANGE) whose return
value can vary depending on the platform. Which breaks the unit test.
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
read_in_chunks does not clear the intermediate string 'str'
between iterations, so every chunk has every other chunk prepended
to it.
A secondary issue is that it calls str2wcstring() on an intermediate
chunk, which may split multi-byte sequences. This needs to be deferred
to the end.
Test added. Fixes#3756
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
