* Clarify dependencies: required vs optional, and build vs runtime.
A first pass at updating the dependency documentation, based on the
discussion in this thread:
https://github.com/fish-shell/fish-shell/issues/2062
* Clarify notes on dependency errors, tests, and VCS integration.
An optional feature that suggests you install Python is okay;
core-dumping is not.
The note on tests was about fish development tests, not the `test`
builtin for conditional syntax.
Specifically mention git, hg, and svn in the VCS section.
I recently noticed there were several invocations of `wcwidth()` that should
have been `fish_wcwidth()`. This adds custom cppcheck rules to detect that
mistake.
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 OS X Xcode IDE has a weird requirement that block comments preceding a
function or class definition must begin with three slashes rather than two if
you want the comment displayed in the "Quick Help" window.
If there are uncommitted changes use `git-clang-format` to limit the style
fixups to the lines being modified.
Refuse to do a `make style-all` if there are uncommitted changes.
Include a fix for the parsing of `git status` output that was recently
incorporated into the lint.fish script.
Include information about how to deal with lint warnings and suppress
`clang-format` reformatting of blocks of code.
Move information only relevant to developers from the README.md to the
CONTRIBUTING.md document.
Closes#2901
This changes implements two new make targets: `style` and `style-all`. These
make it easy to ensure that a change conforms to the project style guides for
C++ and fish code.
Fixes#571
