There should be just one place that calls `setupterm()`. While refactoring
the code I also decided to not make initializing the curses subsystem a
fatal error. We now try two fallback terminal names ("ansi" and "dumb")
and if those can't be used we still end up with a usable shell.
Fixes#3850
I recently upgraded the software on my macOS server and was dismayed to
see that cppcheck reported a huge number of format string errors due to
mismatches between the format string and its arguments from calls to
`assert()`. It turns out they are due to the macOS header using `%lu`
for the line number which is obviously wrong since it is using the C
preprocessor `__LINE__` symbol which evaluates to a signed int.
I also noticed that the macOS implementation writes to stdout, rather
than stderr. It also uses `printf()` which can be a problem on some
platforms if the stream is already in wide mode which is the normal case
for fish.
So implement our own `assert()` implementation. This also eliminates
double-negative warnings that we get from some of our calls to
`assert()` on some platforms by oclint.
Also reimplement the `DIE()` macro in terms of our internal
implementation.
Rewrite `assert(0 && msg)` statements to `DIE(msg)` for clarity and to
eliminate oclint warnings about constant expressions.
Fixes#3276, albeit not in the fashion I originally envisioned.
On some platforms, notably GNU libc, you cannot mix narrow and wide
stdio functions on a stream like stdout or stderr. Doing so will drop
the output of one or the other. This change makes all output to the
stderr stream consistently use the wide forms.
This change also converts some fprintf(stderr,...) calls to debug()
calls where appropriate.
Fixes#3692
Make `fish_indent`, `fish_key_reader` and `fish` recognize and assign
the same meaning to the `-d` and `-D` flags. Also, fix some errors and
stylistic issues in the associated man pages.
Fixes#3191
After the colorized syntax output in type -a foo, "foo is /usr/..."
would also be colored. (or 'test' in fish_indent foo.fish; echo test).
Make fish_indent reset the color when it's done.
When given no path, the logic was happy to try to use
an unitialized output_location.
$ fish_indent -w < test.fish
Opening "(null)" failed: Bad address
Initialize the string, and repair the logic to catch this case
and report the problem correctly.
Fix test setup bogosities. Specifically, they weren't hermetic with respect to
locale env vars.
Rewrite the handling of locale vars to simplify the code and make it more like
the pattern most programs employ.
Fixes#3110
This change allows the user to specify the script name on the CLI in addition
to being redirected from stdin. It also adds a `-w` flag to write the modified
script to the original file.
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.
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
In keeping with the change made by @ridiculousfish earlier today modify
the `keyword_description()` function to return a const wchar_t pointer.
Also, simplify the `token_type_description()` function to use the recently
introduced mapping array. This changes the wording of many of the token
type descriptions. However, I can't see this as being a problem since
the original descriptions (e.g., "token_redirection") are no clearer to
someone not acquainted with the implementation.
Fish keywords can be quoted and split across lines. Prior to this change
`fish_indent` would retain such odd, obfuscated, formatting. This change
results in all keywords being converted to their canonical form.
This required fixing a bug: the keyword member of parse_node_t wasn't being
populated. This hadn't been noticed prior to now because it wasn't used.
Fixes#2921
Modify `fish_indent` to emit redirections without a space before the target of
the redirection; e.g., "2>&1" rather than "2>& 1" as the former is clearer to
humans.
Fixes#2899
There is no longer a good reason to detect whether or not getopt_long()
is available. All UNIX implementations we're likely to run on have it. And
if we ever find one that doesn't the right thing to do is not fallback to
getopt() but to include the getopt_long() source in our package like we
do with the pcre2 library. Since it's licensed under LGPL we can legally
do so if it becomes necessary.
This partially addresses issue #2790.
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
