This is somehow an extension for the ccache completion for zsh.
That completion can complete ccache ⇥ and export SOME_CCACHE_VARIABLE=⇥,
but it cannot do export CCACHE_⇥. This is what I add in the completion
function here. It is a bit hacky (and at the time of writing not complete), but
you can give it a try. One part that made it especially hacky (and I should get
in contact with the zsh maintainers if we can do something better on the zsh
side) is that I want "tooltips" for the ccache variable names:
user@host somedir >> export CCACHE_⇥
ccache variables:
CCACHE_BASEDIR -- relative to which top level paths are hashed
CCACHE_CC -- specify compiler
CCACHE_COMPILERCHECK -- compiler information included in the hash
CCACHE_COMPRESSLEVEL -- cache compression level
CCACHE_DIR -- where the cache and config are kept
CCACHE_EXTENSION -- set extensions for intermediate files
CCACHE_EXTRAFILES -- additional files to consider in hashing
CCACHE_IGNOREHEADERS -- set paths to headers to ignore in hashing
CCACHE_LIMIT_MULTIPLE -- cleanup level
CCACHE_LOGFILE -- specify a log file
CCACHE_MAXFILES -- maximum number of files in the cache
CCACHE_MAXSIZE -- maximum size of the cache
CCACHE_NLEVELS -- directory levels in the cache directory
CCACHE_PATH -- path to the ccache directory
CCACHE_PREFIX -- prefixes for compiler invokation
CCACHE_PREFIX_CPP -- prefixes for preprocessor invokation
CCACHE_SLOPPINESS -- hash files sloppy
CCACHE_TEMPDIR -- where temporary files are kept
CCACHE_UMASK -- set umask for ccache and child processes (e.g. for sharing cache)
