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.
0 is not a good default PGID, because it's possible for a kernel process
to have the PGID of 0 under Linux.
This meant that job_get_from_pid could return incorrect jobs, as the PGID
for internal, non-forked jobs was the same as kernel processes.
Avoid this by using an invalid PGID as the initial PGID.
It is possible for fish to not be the process group leader; avoid
signalling the process group containing the current process by checking
with getpgrp() rather than assuming that getpid() is enough.
If fish is not the first process in a pipeline, and jobs are started
from the fish process, it is possible for fish and the OS to have
different ideas about what the process group of the jobs are.
This change confirms the current PGID, rather than assuming that it is
the same as the PID.
Defining aliases for existing symbols serves only to obscure the code.
So remove the following symbols and replace them with the primary
symbols:
enum { BUILTIN_TEST_SUCCESS = STATUS_BUILTIN_OK, BUILTIN_TEST_FAIL =
STATUS_BUILTIN_ERROR };
See issue #3985.
Per my comment in issue #3980 this implements `__fish_print_users` in
terms of `__fish_complete_users` so we don't have to modify both when a
change to how users are enumerated is needed.
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 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.
This has the side benefit of working around a wild bug with readline+fish that I've reported to the upstream readline developers. (The result of that bug is that the hg processes are constantly being leaked as `bg` jobs in the shell, which is how I came to notice this in the first place)
This removes a need for packagers to either patch our shebangs or pick
a particular python.
This was already done in __fish_config_interactive (where we need to
duplicate the code because it involves backgrounding).
Work towards #3970.
Fedora puts them in /usr/lib64 without having /usr/lib as a symlink.
Also silence errors (in case a directory doesn't exist) and stringify.

CC @amluto.
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'.
