GetOrDetermineLanguage:
- Read the property if available
- Determine the Language using the file extension
Fix all usage of the non-const member in the repository.
This adds the following functions to `cmStringAlgorithms`:
- `cmIsSpace`
- `cmTrimWhitespace` (moved from `cmSystemTools::TrimWhitespace`)
- `cmEscapeQuotes` (moved from `cmSystemTools::EscapeQuotes`)
- `cmTokenize` (moved from `cmSystemTools::tokenize` and adapted to
accept `cm::string_view`)
Since commit e89ad0f94e (install: Allow installing targets created in
another directory, 2018-06-18, v3.13.0-rc1~407^2) we support calling
`install(TARGETS)` for targets created in another directory. However,
install generators are associated with the directory in which the call
to `install()` appears. This may not be the same directory in which the
target is defined. Record in each target the list of install generators
it has.
Fixes: #19546
Previously we computed the entire description of each source file
including all target-wide settings, and then computed compile groups
using those complete descriptions. This is inefficient when target-wide
settings are large because they are included in comparisons even though
they are the same for every source. Instead compute source groups using
only the source-specific settings, and then merge the target-wide
settings into place only once per unique compile group.
This is a slight behavior change in the case that a source-specific
compile definition duplicates a target-wide definition. Previously that
source would still be grouped with other sources which do not have the
definition because they would all get it from the target. Now that
source will be in its own compile group even though it ultimately
compiles with the same settings as another group. This is acceptable
because the source is specified by the project with source-specific
settings already.
Fixes: #19520
Previously we converted the description of each source file into its
compile group Json object and then used the Json object itself as a
unique identifier for the group. When source files have large
descriptions their Json objects make inefficient map keys requiring deep
comparison operations. Instead use our internal `CompileData` structure
as a map key. This enables use of a hash map.
Issue: #19520
Convert from `cmListFileBacktrace` to Json `backtraceGraph` entries
before storing in `CompileData`. This will allow backtraces to be
uniquely identified, hashed, and compared as a single integer.
An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
This patch strips the `stripImplicitDirs` and `appendAllImplicitDirs`
parameters from the `cmLocalGenerator::GetIncludeDirectories` method and makes
it a wrapper into the new `cmLocalGenerator::GetIncludeDirectoriesImplicit`
method. `cmLocalGenerator::GetIncludeDirectoriesImplicit` is the renamed old
implementation of `cmLocalGenerator::GetIncludeDirectories` and still
accepts `stripImplicitDirs` and `appendAllImplicitDirs`.
The motivation is that there's only *one* case where
`cmLocalGenerator::GetIncludeDirectories` is called with the
`stripImplicitDirs` parameter being `false` (QtAutoGen), but many other places
where it is called using the `true` default value.
QtAutoGen is modified to use `cmLocalGenerator::GetIncludeDirectoriesImplicit`
directly. In two use cases of `cmLocalGenerator::GetIncludeDirectories`
the manually set `true` value for `stripImplicitDirs` is removed.
Offer clients a `project()`-centric view of the build system. This is
similar to the directory-centric view but consolidates subdirectories
that do not call `project()` with a new project name.
