I have implemented the setter for the new option locally and tested it in
KDevelop.
void clang_CXIndex_setStorePreamblesInMemory(CXIndex CIdx,
int storePreamblesInMemory) {
if (CIdx)
static_cast<CIndexer *>(CIdx)->setStorePreamblesInMemory(
storePreamblesInMemory);
}
Works as expected: new preambles are created in memory or the temporary
directory depending on the option selected in the UI. Even if the temporary
storage option ends up in memory, all remaining preambles are removed from the
temporary directory on exit.
This simple setter approach was rejected in recent comments under D143418
<https://reviews.llvm.org/D143418> for valid reasons. But this quick test
proves that changing the option on the fly is viable. Currently I don't think
that the option change taking effect without restarting KDevelop justifies the
effort of implementing the setter as `clang_parseTranslationUnitWithOptions()`.
I expect this option's value to be changed very rarely. So I don't plan to
change preamble storage API after this review.
