Fixes various spots throughout fish where broken strtoi checks
were converting empty strings to zero. Zero is not a valid pid and
this was causing breakage as well when input.
Nix fish_wcstoi - wcstoimax does the same thing.
Improve comments and some general cleanup.
This only eliminates errors reported by `make lint`. It shouldn't cause any
functional changes.
This change does remove several functions that are unused. It also removes the
`desc_arr` variable which is both unused and out of date with reality.
The autoconf-generated config.h contains a number of directives which
may alter the behaviour of system headers on certain platforms. Always
include it in every C++ file as the first include.
Closes#2993.
I'm doing this as part of fixing issue #2980. The code for managing tty modes
and job control is a horrible mess. This is a very tiny step towards improving
the situation.
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes#2957
This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes#1866
