This list can than be used in +# conjuction with functions like "add_executable" or others to create the +# neccessary compile rules with CMake. +# +# The initial variable is followed by a list of .vala files to be compiled. +# Please take care to add every vala file belonging to the currently compiled +# project or library as Vala will otherwise not be able to resolve all +# dependencies. +# +# The following sections may be specified afterwards to provide certain options +# to the vala compiler: +# +# PACKAGES +# A list of vala packages/libraries to be used during the compile cycle. The +# package names are exactly the same, as they would be passed to the valac +# "--pkg=" option. +# +# OPTIONS +# A list of optional options to be passed to the valac executable. This can be +# used to pass "--thread" for example to enable multi-threading support. +# +# CUSTOM_VAPIS +# A list of custom vapi files to be included for compilation. This can be +# useful to include freshly created vala libraries without having to install +# them in the system. +# +# GENERATE_VAPI +# Pass all the needed flags to the compiler to create an internal vapi for +# the compiled library. The provided name will be used for this and a +# <provided_name>.vapi file will be created. +# +# GENERATE_HEADER +# Let the compiler generate a header file for the compiled code. There will +# be a header file as well as an internal header file being generated called +# <provided_name>.h and <provided_name>_internal.h +# +# The following call is a simple example to the vala_precompile macro showing +# an example to every of the optional sections: +# +# vala_precompile(VALA_C +# source1.vala +# source2.vala +# source3.vala +# PACKAGES +# gtk+-2.0 +# gio-1.0 +# posix +# OPTIONS +# --thread +# CUSTOM_VAPIS +# some_vapi.vapi +# GENERATE_VAPI +# myvapi +# GENERATE_HEADER +# myheader +# ) +# +# Most important is the variable VALA_C which will contain all the generated c +# file names after the call. +## + +macro(vala_precompile output) + include_directories(${CMAKE_CURRENT_BINARY_DIR}) + parse_arguments(ARGS "PACKAGES;OPTIONS;GENERATE_HEADER;GENERATE_VAPI;CUSTOM_VAPIS" "" ${ARGN}) + set(vala_pkg_opts "") + foreach(pkg ${ARGS_PACKAGES}) + list(APPEND vala_pkg_opts "--pkg=${pkg}") + endforeach(pkg ${ARGS_PACKAGES}) + set(in_files "") + set(out_files "") + set(${output} "") + foreach(src ${ARGS_DEFAULT_ARGS}) + list(APPEND in_files "${CMAKE_CURRENT_SOURCE_DIR}/${src}") + string(REPLACE ".vala" ".c" src ${src}) + set(out_file "${CMAKE_CURRENT_BINARY_DIR}/${src}") + list(APPEND out_files "${CMAKE_CURRENT_BINARY_DIR}/${src}") + list(APPEND ${output} ${out_file}) + endforeach(src ${ARGS_DEFAULT_ARGS}) + + set(vapi_arguments "") + if(ARGS_GENERATE_VAPI) + list(APPEND out_files "${CMAKE_CURRENT_BINARY_DIR}/${ARGS_GENERATE_VAPI}.vapi") + set(vapi_arguments "--internal-vapi=${ARGS_GENERATE_VAPI}.vapi") + + # Header and internal header is needed to generate internal vapi + if (NOT ARGS_GENERATE_HEADER) + set(ARGS_GENERATE_HEADER ${ARGS_GENERATE_VAPI}) + endif(NOT ARGS_GENERATE_HEADER) + endif(ARGS_GENERATE_VAPI) + + set(header_arguments "") + if(ARGS_GENERATE_HEADER) + list(APPEND out_files "${CMAKE_CURRENT_BINARY_DIR}/${ARGS_GENERATE_HEADER}.h") + list(APPEND out_files "${CMAKE_CURRENT_BINARY_DIR}/${ARGS_GENERATE_HEADER}_internal.h") + list(APPEND header_arguments "--header=${ARGS_GENERATE_HEADER}.h") + list(APPEND header_arguments "--internal-header=${ARGS_GENERATE_HEADER}_internal.h") + endif(ARGS_GENERATE_HEADER) + + add_custom_command(OUTPUT ${out_files} + COMMAND + ${VALA_EXECUTABLE} + ARGS + "-C" + ${header_arguments} + ${vapi_arguments} + "-b" ${CMAKE_CURRENT_SOURCE_DIR} + "-d" ${CMAKE_CURRENT_BINARY_DIR} + ${vala_pkg_opts} + ${ARGS_OPTIONS} + ${in_files} + ${ARGS_CUSTOM_VAPIS} + DEPENDS + ${in_files} + ${ARGS_CUSTOM_VAPIS} + ) +endmacro(vala_precompile) |
