...starting from a template (aka configuration file), and using the
variables defined via a ["CC/auto", "config"] target.
For example, to use a CMake configuration file, the targets could be
defined as follows
...
, "foo-header-blueprint":
{ "type": ["@", "rules", "CC/auto", "config_file"]
, "input": ["config.hpp.in"]
, "output": ["config.hpp"]
, "stage": ["foo"]
, "magic_string": ["cmakedefine"]
, "@only": ["true"]
}
, "foo-header":
{ "type": "configure"
, "target": "foo-header-blueprint"
, "config":
{ "type": "let*"
, "bindings":
[ [ "defines"
, [ ["var", "\"string value\""]
, ["FOO_MAJOR_VERSION", "3"]
, ["use_this_feature", true]
]
]
]
, "body": {"type": "env", "vars": ["defines"]}
}
}
...
The file config.hpp.in may look as follows
#ifndef config_cmake
#define config_cmake
#cmakedefine var
#cmakedefine use_this_feature
#cmakedefine01 use_this_feature
#cmakedefine unused
#define FOO_VERSION @FOO_MAJOR_VERSION@
#define DONT_TOUCH_THIS ${FOO_MAJOR_VERSION}
#endif
and the generated configuration file foo/config.hpp is
#ifndef config_cmake
#define config_cmake
#define var "string value"
#define use_this_feature
#define use_this_feature 1
/* #undef unused */
#define FOO_VERSION 3
#define DONT_TOUCH_THIS ${FOO_MAJOR_VERSION}
#endif

Compared to the previous commit, the action graphs for just
and its unit tests are unchanged.
- Git hash of action graph for ["",""]:
c6e75f17abd7ffaab6ff9bb725ad67ec0bf6c973
- Git hash of action graph for ["test/buildtool","TESTS"]:
8063dfb3dd7daa9ae01d95c177e14946f785c57e
Refactor:
- "local cflags" to "private-cflags"
- "local defines" to "private-defines"
- "link externals" to "private-ldflags"
- "deps" to "private-deps" for (test) binaries
- "proto" to "private-proto" for binaries
Improvements:
- consistent variable declaration order:
OS, ARCH, HOST_ARCH, TARGET_ARCH,
CC, CXX, CFLAGS, CXXFLAGS, ADD_CFLAGS, ADD_CXXFLAGS,
AR, ENV, PATH
- use fields close to their definition (in RULES)
- use common expression for binaries and test binaries
- split expression "flags" and "compiler"
... to separate ones for CC and CXX.
- rename "transition" to "deps-transition"
... to avoid conflicts with other transitions.
- support "defaults-transition" for CC expressions
Implement:
- "cflags" for libraries
- "private-cflags" for (test) binaries
- "private-defines" for test binaries
- "private-ldflags" for test binaries
- (public) "defines" for libraries
