Hi,
I guess it is a well known fact that cmake command is almost never
executed alone and for non-trivial examples usually hold some extra
arguments (home directory, build directory, verbosity level, toolchains,
options, ...). Also I guess that such commands doesn't change from
day-to-day development process and an obvious way to reduce typing is to
create wrapper build scripts (.bat or .sh, I personally use a Python one).
I have next suggestion of how it can be unified: introduce ini-like file
(say ${HOME}/.configs/cmake/alias) with alias sections with frequently
used generators/arguments.
Example of such file:
[default]
var: CMAKE_VERBOSE_MAKEFILE=ON
home: .
build-dir: _builds/default
[clean]
cmd: cmake -E remove_directory _builds
[vs-12]
inherit: default
generator: Visual Studio 12 2013
build-dir: _builds/vs-12
[iphone]
inherit: default
generator: Xcode
build-dir: _builds/ios-9-2
var: CMAKE_TOOLCHAIN_FILE=/.../ios-9-2.cmake
[ipad]
inherit: default
generator: Xcode
build-dir: _builds/ios-9-1
var: CMAKE_TOOLCHAIN_FILE=/.../ios-9-1.cmake
Usage:
> cmake -c clean ipad
effectively equivalent to:
> cmake -E remove_directory _builds
> cmake -H. -B_builds/ios-9-2 -DCMAKE_VERBOSE_MAKEFILE=ON -GXcode
-DCMAKE_TOOLCHAIN_FILE=/.../ios-9-2.cmake
Name of the options may be:
-c # classes (sectioins can be inherited)
-a # alias
-m # meta-targets
For now it's just a thought and I have no idea how it will work on
practice so I can create a fork for experimenting. And if it will work
fine for me I'm planning to add such feature to CMake upstream, so I'm
ready to hear an appropriate implementation details.
Thoughts?
