maybe_t is an implementation of the Maybe/Optional type, allowing
for an optional value to be stored. This will enable a more
principled approach for functions that return values or failure,
such as env_get.
We've needed a fishy way to parse flags and arguments given to scripts
and functions for a very long time. In particular a manner that provides
the same behavior implemented by builtin commands. The long term goal is
to support DocOpt. But since it is unclear when that will happen so this
implements a `argparse` command. So named as homage to the excellent
Python module of the same name.
Fixes#4190
This commit does a few things:
- Switches to C++11 as the language dialect
- Eliminates the Release_C++11 configuration (now C++11 is default)
- Switches to libc++ from libstdc++, since the libstdc++ that ships
with Xcode does not support C++11
- Add options to the autotools build to set the path for the "vendor"
or "extra" configuration snippets, functions and completions
directories.
- Remove the vendor_completions directory from the Xcode build, as
these are relocatable and compiling the paths in does not make sense.
This allows packaging tools like Homebrew and Nix to use a common
directory outside of the main prefix for third-party completions, and
to make these available for programmatic discovery through `pkg-config`.
Closes#2113
Instead of duplicating the script invocation across targets,
put it into a separate target and add dependencies. This also
requires moving its output into the SHARED_DERIVED_FILE_DIR
(which may be undocumented)?
Teach Xcode to run new script xcode_version_gen.sh before building
the fish_shell and fish_indent targets. The script generates file
fish-build-version.h for inclusion by fish_version.cpp.
Note that Xcode always runs the script because of the phony target
named force-fish-build-version.h, but fish-build-version.h is only
touched if the contents of FISH-BUILD-VERSION-FILE change.
