Doing it in the parser meant only top-level jobs would be reaped after
being `disown`ed, as subjobs aren't directly handled by the parser.
This is also much cleaner, as now job removal is centralized in
`process_clean_after_marking()`.
Closes#5803.
This prevents the `disown` builtin from directly removing jobs out of
the jobs list to prevent sanity issues, as `disown` may be called within
the context of a subjob (e.g. in a function or block) in which case the
parent job might not yet be done with the reference to the child job.
Instead, a flag is set and the parser removes the job from the list only
after the entire execution chain has completed.
Closes#5720.
This lets non-developers simply `cd` into the fish source directory and
execute `make` to build the project. The Makefile searches for CMake and
hands over the build to it if it is available, otherwise an error
message is emitted. All dependency checking is left to CMake.
Non-fish-devs shouldn't have to concern themselves with what build
system fish developers have chosen, and building a random C++ project
should not be a chore in familiarizing one's self with all the various
build platforms out there.
CMake is instructed to use `ninja` if it is available, otherwise the
standard Unix Makefiles generator option is used.
(This has already been the behavior on BSDs since CMake was adopted.)
There's an explicit label for "cartesian-product", but the title is
"Cartesian Product*s*". So linking via with `thing <#link>`_ links the
title, so without the "s" it doesn't work.
From what I know, linking via :ref:`thing <label>` is preferred and
works better with other exports and across files?
I think I should take a doc holiday.

No longer uses global vars to cache set_color output, this was
from before set_color was a builtin, it is pointless now.
This is also a prompt from before we had bright named colors,
and it appears it was relying on -o red to get bright red.
so use brred, etc.
This merges a bunch of changes that migrate logic from env.cpp to a new file
env_dispatch.cpp. env_dispatch is concerned with dispatching changes to
variables, while env.cpp is the "core."
When popping a scope from the environment stack, we currently do a lot of
nonsense like looking for changed curses variables. We want to centralize
this in env_stack_t so that it can be migrated to the env_dispatch logic.
Move this logic up one level in preparation for doing that.
This new file is supposed to encapsulate all of the logic around
reacting to variable changes, as opposed to the environment core.
This is to help break up the env.cpp monolith.
Prior to this fix, a job would only inherit a pgrp from its parent if the
first command were external. There seems to be no reason for this
restriction and this causes tcsetgrp() churn, potentially cuasing SIGTTIN.
Switch to unconditionally inheriting a pgrp from parents.
This should fix most of #5765, the only remaining question is
tcsetpgrp from builtins.
