This potentially leads to an unusable session (when fish_key_bindings is
set in config.fish to a value without corresponding function), so we
should take care.
* Add missing color definitions to __fish_init_1_50_0 reset.
The values where determined by inspecting the values of:
* fish_color_end
* fish_color_user
* fish_color_host
after resetting the color theme via fish_config.
* Add documentation for fish_color_user and fish_color_host.

I noticed that the `test_convert()` function was randomly failing when
run on OS X Snow Leopard. I tracked it down to the `mbrtowc()` function on
that OS being broken. Explicitly testing for UTF-8 prefixes that identify
a sequence longer than four bytes (which the Unicode standard made illegal
long ago) keeps us from having encoding errors on those OS's.
This also makes the errors reported by the `test_convert()` function actually
useful and readable.
Lastly, it makes it possible to build fish on OS X Snow Leopard.
This is quite ugly because the syntax is ugly, the documentation both
under- and overspecified at the same time (a BNF that isn't...) and it
has a lot of functionality.
But the completion works half-decent for `ip address`, so let's ship it.
Drops configure check for wcsdup, wcslen, wcscasecmp, wcsncasecmp,
wcwidth, wcswidth, wcstok, fputwc, fgetwc, and wcstol. Drop the fallback
implementations of these on non-Snow Leopard platforms.
Work on #2999.
fwprintf would segfault on DragonFly BSD 1.4.0, released in January
2006. This was fixed by DragonFly BSD 1.4.4, released in April 2006. It
seems unlikely that anyone is still running a ten-year-old, unsupported
version, and hoping that fish will continue to build.
I've checked this in virtual machines.
Work on #2999.
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.
Instead of just using Courier New across the board, have the
browser try several likely available fonts before defaulting
to the system's "monospace".
Thanks @MarkGriffiths
Fixes#2924
This change does several things. First, and most important, it allows
dumping the "n" most recent stack frames on each debug() call. Second,
it demangles the C++ symbols. Third, it prepends each debug() message
with the debug level.
Unrelated to the above I've replaced all `assert(!is_forked_child());`
statements with `ASSERT_IS_NOT_FORKED_CHILD()` for consistency.
Fix a minor bogosity I noticed while building fish on OS X Snow
Leopard. It's technically not a bug because only old compilers complain
about the original statement but this change makes the one line this
changes consistent with the rest of the fish code.
It's currently too easy for someone to bork their shell by doing something
like `function test; return 0; end`. That's obviously a silly, contrived,
example but the point is that novice users who learn about functions are
prone to do something like that without realizing it will bork the shell. Even
expert users who know about the `test` builtin might forget that, say, `pwd`
is a builtin.
This change adds a `--shadow-builtin` flag that must be specified to
indicate you know what you're doing.
Fixes#3000
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.
The original `key_reader` program was useful but didn't do much that `xxd`
or `od -tx1z` didn't do. Furthermore, it wasn't built and installed by
default. This change adds features that make it superior to those programs
for decoding interactive key presses and makes it a first-class citizen
like the `fish_indent` program that is always available.
Fixes#2991
I'm going to modify these functions as part of dealing with issue #3000
and don't want those changes to be masked by running the files through
`make style`.
