wopterr was a feature to allow wgetopt to emit error messages; but we do
not use this and never will. Remove its support. No functional change
expected here.
The "flag" field enables an option to discover which flag it was invoked
with. However in practice none of our options use multiple flags so this
parameter was always nullptr. Remove it and fix up all the builtins to
stop passing this.
No functional change here.
Let's hope this doesn't causes build failures for e.g. musl: I just
know it's good on macOS and our Linux CI.
It's been a long time.
One fix this brings, is I discovered we #include assert.h or cassert
in a lot of places. If those ever happen to be in a file that doesn't
include common.h, or we are before common.h gets included, we're
unawaringly working with the system 'assert' macro again, which
may get disabled for debug builds or at least has different
behavior on crash. We undef 'assert' and redefine it in common.h.
Those were all eliminated, except in one catch-22 spot for
maybe.h: it can't include common.h. A fix might be to
make a fish_assert.h that *usually* common.h exports.
1. Bravely use a real enum for has_arg, despite the warnings.
2. Use some C++11 initializers so we don't have to pass an int for this
parameter.
No functional change expected here.
Prior to this change, builtins would take their arguments as `wchar_t **`.
This implies that the order of the arguments may be changed (which is
true, `wgetopter` does so) but also that the strings themselves may be
changed, which no builtin should do.
Switch them all to take `const wchar_t **` instead: now the arguments may
be rearranged but their contents may no longer be modified.
Putting larger members before smaller ones will reduce structure
sizes. bools are 1 byte. on 64bit systems I think they reduced:
wgetopt.h:46: 64 to 56 bytes
builtin_history.cpp:30: 48 to 32 bytes
builtin_status.cpp:91: 32 to 24 bytes
tinyexpr.cpp:69: 40 to 32 bytes
I missed restyling a few "switch" blocks to make them consistent with the rest
of the code base. This fixes that oversight. This should be the final step in
restyling the C++ code to have a consistent style. This also includes a few
trivial cleanups elsewhere.
I also missed restyling the "complete" module when working my way from a to z
so this final change includes restyling that module.
Total lint errors decreased 36%. Cppcheck errors went from 47 to 24. Oclint P2
errors went from 819 to 778. Oclint P3 errors went from 3252 to 1842.
Resolves#2902.
For this change I decided to bundle the remaining modules that need to be
resytyled because only two were large enough to warrant doing on their own.
Reduces lint errors from 225 to 162 (-28%). Line count from 3073 to 2465 (-20%).
Another step in resolving issue #2902.
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
The argv argument may be modified on calls to exchange within the function and should not be const qualified (it's not true from the caller's point of view).
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
