ADFA-2717: Add a C/C++ new-file dialog for cpp source folders - #2101
Daniel-ADFA wants to merge 1 commit into
Conversation
New file on a src/<sourceSet>/cpp folder now asks for C or C++ and for Source, Header or Class (C++ only), instead of a bare name prompt. Headers get an include guard; a class creates Name.h declaring it and Name.cpp including it. Existing files are never overwritten.

Handle native dialog filesystem errors.
File.exists() can throw SecurityException, and the native click callback does not catch it. The preceding validation makes the stated NativeSourceBuilder.createFiles IllegalArgumentException path unreachable for normal input. FileActionManager.createFile already handles its own IllegalArgumentException and reports failures asynchronously.
Add the same cancellation-preserving handler used by createJavaClass around doCreateNativeSource.

- doCreateNativeSource(binding, directory, node)
+ try {
+ doCreateNativeSource(binding, directory, node)

Header guard for a name that starts with an underscore is reserved.
For a name such as _impl2, the guard becomes _IMPL2_H. An identifier that starts with an underscore followed by an uppercase letter is reserved for the implementation. FILE_NAME allows a leading underscore, so this case is reachable. Prefix the guard with a letter when the name starts with _. Update the test expectations if you add this.
Proposed fix
- val guard = "${name.uppercase(Locale.ROOT).replace('-', '_')}_H"
+ val base = name.uppercase(Locale.ROOT).replace('-', '_')
+ val guard = "${if (base.startsWith("_")) "H" else ""}${base}_H"Based on learnings: avoid header guards that start with an underscore followed by an uppercase letter, because such identifiers are reserved for the implementation.
