Stefan Kislinskiy ca6ba3fee5 Genex: Add a SHELL_PATH expression
Some commands on Windows do not understand forward slash paths and
require backslashes.  In order to help projects generate shell
invocations of such commands, provide a generator expression to convert
paths to the shell-preferred path format for the current generator.
This will allow custom commands to generate paths the same way CMake
does for compiler command invocations.

Stephen Kelly 5de63265e3 Genex: Only evaluate TARGET_OBJECTS to determine target sources.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc.  To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.

This commit may be reverted in the future if a solution to the
above difference is implemented.

Stephen Kelly e5da9e51d0 cmTarget: Allow any generator expression in SOURCES property.
Remove use of UseObjectLibraries from Makefile and Ninja generators. It
is not needed now because those generators use GetExternalObjects
which already contains the objects from object libraries.

The VS10 generator calls both the UseObjectLibraries and the GetExternalObjects
methods. Ensure that duplicates are not created by skipping objects
from object libraries in handling of GetExternalObjects.

Similarly, fix VS6, VS7 and Xcode object handling by skipping
external objects from OBJECT_LIBRARY usage as appropriate.

The error message in the BadSourceExpression1 test is now reported
by the generator expression evaluator, so it has different text.

Stephen Kelly 3917d86b26 Genex: Add a nullary form for CONFIG
This is consistent with other similar expressions such as PLATFORM_ID,
and makes the CONFIGURATION expression obsolete.

Fix an off-by-one error in
GeneratorExpressionContent::EvaluateParameters exposed by a unit test.

Remove the test for 'bad' nullary use of $<CONFIG>.

Add a unit test to verify that $<CONFIG> and $<CONFIGURATION> have
the same value.

Ben Boeckel d331292c12 cmTestGenerator: Evaluate generator expressions in test properties
This is useful for cases like:

  add_test(NAME mytest COMMAND mydriver $<TARGET_FILE:myexe>)
  set_tests_properties(mytest PROPERTIES
    REQUIRED_FILES "$<TARGET_FILE:myexe>"
    WORKING_DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}/$<CONFIGURATION>"
    )

In this example we require the actual test executable to exist to
run the test in addition to the test driver at argv[0].  Also the
$<CONFIGURATION> expression improves over \${CTEST_CONFIGURATION_TYPE}
because the latter is not normalized for case-sensitive filesystems.

Stephen Kelly 36eef302c0 Genex: Fix segfault when parsing ends with parameter expectation.
The extendResult method expects a non-empty parameters vector, as
assured by the normal case. Avoid calling the method when the parser
finds an incomplete generator expression, but has already entered
the state of expecting to find parameters.

Stephen Kelly 370bf55415 Add the ALIAS target concept for libraries and executables.
* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
  of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
  and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
  target property.
* An ALIAS does not appear in the generated buildsystem. It
  is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.

Stephen Kelly 10a069b504 Genex: Fix $<CONFIG> with IMPORTED targets and multiple locations.
The old code checked only that there was a LOCATION for the

mapped.

Jean-Christophe Fillion-Robin 7f3bb8b392 Add $<SEMICOLON> generator expression.
This expression is useful to put a ';' in a command line argument
without dividing the argument during CMake list expansion.
2013-03-12 16:46:03 -04:00
Stephen Kelly 7e707444be Expand includes and defines transitively in 'external' genexes.
This means that we can use expressions of the form

 $<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>

to get a list of the interface include directories of foo, including
those coming from dependencies.

We can't have a test of a target which has a single include directory in
its INCLUDE_DIRECTORIES because the shell on the MSYS platforms transforms
a single include directory to include a prefix, which is not what the test
expects. We test a target with two directories instead as a means to
test a target with no link dependencies.

Stephen Kelly df4d2b28b2 Make it an error for INSTALL_PREFIX to be evaluated.
An empty string is not likely going to produce expected results
in any evaluation context. It is replaced by preprocessing
currently.

Stephen Kelly b2f1700bc7 GenEx: Add expressions to specify build- or install-only values
This is for specifying INCLUDE_DIRECTORIES relevant to the build-location
or the install location for example:

 set_property(TARGET foo PROPERTY
   INTERFACE_INCLUDE_DIRECTORIES
   "$<BUILD_INTERFACE:${CMAKE_CURRENT_BINARY_DIR};${CMAKE_CURRENT_SOURCE_DIR}>"
   "$<INSTALL_INTERFACE:${CMAKE_INSTALL_PREFIX}/include>"
 )

A 'bar' target can then use:

 set_property(TARGET bar PROPERTY
   INCLUDE_DIRECTORIES
   "$<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>"
 )

and it will work whether foo is in the same project, or an imported target
from an installation location, or an imported target from a build location
generated by the export() command.

Because the generator expressions are only evaluated at build-time, these
new expressions are equivalent to the ZeroNode and OneNode.

The GeneratorExpression test is split into parts. Some shells can't run
the custom command as it is getting too long.

Stephen Kelly 4bacff7a4c GenEx: Test early determination of AND and OR
It should be possible for example to do this:

 "$<AND:${FOO},$<BOOL:${TGT}>,$<BOOL:$<TARGET_PROPERTY:${TGT},PROP>"

such that it works simliarly to the C code:

 if (foo && tgt && tgt->prop())
   {
   }

The example of generator expression code is a little bit contrived as
it could be written other ways with the same functionality. Nevertheless,
as these cases already work and are intentional, test for them.

Stephen Kelly f7ef32b00b GenEx: Replace some failing tests with Borland and NMake makefiles.

Stephen Kelly e7230c71fd GenEx: Fix termination bugs in generator expression parser.
Content which is incomplete as a generator expression could cause
segfaults by advancing an iterator beyond end() and dereferencing
it. Such incomplete generator expressions  should be treated as
plain text instead.

Stephen Kelly e2d141d474 GenEx: Parse colon after arguments separator colon specially.
The rationale is similar to that in commit b3d8f5da (GenEx: Parse comma
after colon tokens specially, 2012-10-04), in that colon tokens should
not be parsed as identifier-argument delimiters after the first colon.

Stephen Kelly b3d8f5dab7 GenEx: Parse comma after colon tokens specially
Otherwise the comma is treated as plain text by ParseContent.

$<STREQUAL:,> should be valid and true.
$<STREQUAL:,something> should be valid and false.

$<STREQUAL:,,> should be non-valid as it is 3 parameters.
$<STREQUAL:something,,> should be non-valid as it is 3 parameters.

Additionally, this allows reporting the correct error for other
expressions. For example $<TARGET_PROPERTY:,> should be invalid
because it has an empty target and empty property. It shouldn't
attempt to read the property ',' on the 'implicit this' target.

Stephen Kelly e028381bf1 Extend the generator expression language with more logic.
Generator expressions for comparing strings, evaluating
strings as booleans, and for creating literal right-angle-brackets
and commas are added. Those may be needed in some cases
where they appear in literals.

Brad King 9d9f616792 Add $<CONFIG:...> boolean query generator expression
This expression evaluates to '1' or '0' to indicate whether the build
configuration for which the expression is evaluated matches tha named
configuration.  In combination with the "$<0:...>" and "$<1:...>"
expressions this allows per-configuration content to be generated.

Brad King ebf05abda1 Add boolean generator expressions
Add generator expressions that combine and use boolean test results:

 $<0:...>         = empty string (ignores "...")
 $<1:...>         = content of "..."
 $<AND:?[,?]...>  = '1' if all '?' are '1', else '0'
 $<OR:?[,?]...>   = '0' if all '?' are '0', else '1'
 $<NOT:?>         = '0' if '?' is '1', else '1'

These will be useful to evaluate (future) boolean query expressions and
condition content on the results.  Include tests and documentation.
