1f06e5f0b9
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

Examples:
|
|
|
|
The command 'gcc -o' requires that a file follows it, so the

NO_COMMON option is suitable. This can be done using the following

|
line:
|
|
|
|
complete -c gcc -s o -r
|
|
|
|
The command 'grep -d' required that one of the strings 'read',
|
|
'skip' or 'recurse' is used. As such, it is suitable to specify that
|
|
a completion requires one of them. This can be done using the

following line:
|
|
|
|
complete -c grep -s d -x -a "read skip recurse"

|

|
\param short_opt The single character name of an option. (-a is a short option,

|
\param long_opt The multi character name of an option. (-a is a short option,

|
|
\param long_mode Whether to use old style, single dash long options.
|
|
\param result_mode Whether to search further completions when this
|
|
completion has been succesfully matched. If result_mode is SHARED,
|
|
any other completions may also be used. If result_mode is NO_FILES,
|
|
file completion should not be used, but other completions may be
|
|
used. If result_mode is NO_COMMON, on option may follow it - only a

parameter. If result_mode is EXCLUSIVE, no option may follow it, and

|
file completion is not performed.
|
|
\param comp A space separated list of completions which may contain subshells.

\param desc A description of the completion.

\param condition a command to be run to check it this completion should be used.
