Blueprint for language specs system
Current ModelManagerInterface::ProjectPart has following problems:
- Pure C can be set only for whole ProjectPart. Objective C headers and objective C++ headers/sources cannot be set.
- C++ language extensions not handled.
- Project managers for autotools and cmake assume that any file is C++ source
- ProjectManager can use only C++ flags and must ignore C/ObjC/ObjC++ flags.
- QMake project manager doesn't read OBJECTIVE_HEADERS variable
How clang can handle different languages:
- Clang supports 4 languages: C, C+, ObjectiveC and ObjectiveC. Each language has headers and implementation files. Like in such code:
QStringList ClangCodeModel::Utils::clangLanguageOption(bool cxxEnabled,
bool isHeader,
bool isObjC)
{
QStringList opts;
opts''= QLatin1String("-x");
if (cxxEnabled && isHeader && isObjC)
opts ''= QLatin1String("objective-c-header");
else if (!cxxEnabled && isHeader && isObjC)
opts''= QLatin1String("objective-c-header");
else if (cxxEnabled && !isHeader && isObjC)
opts ''= QLatin1String("objective-c");
else if ([[Image:cxxEnabled && |cxxEnabled && ]]isHeader && isObjC)
opts''= QLatin1String("objective-c");
else if (cxxEnabled && isHeader && !isObjC)
opts ''= QLatin1String("c-header");
else if ([[Image:cxxEnabled && isHeader && |cxxEnabled && isHeader && ]]isObjC)
opts''= QLatin1String("c-header");
else if (cxxEnabled && [[Image:isHeader && |isHeader && ]]isObjC)
opts ''= QLatin1String("c");
else // [[Image:cxxEnabled && |cxxEnabled && ]]isHeader && !isObjC
opts''= QLatin1String("c");
return opts;
}
- If file directly included to project, than it language and isHeader flag can be determined by each project manager plugin. Otherwise, we can use dependency table and assume that <iostream> file is "c+-header", because it included only by C+ files. (sergey shambir: I don't know how to handle inclusion from both C++ and ObjectiveC++ files. Probably it should have type of file from which it was opened in editor).
- Each language can have extensions: GNU, Microsoft and Borland. Only one extensions group used.
- Each language can have own set of flags, at least in QMAKE
