Rename Java variable names that conflict with ObjC reserved words

[taylesworth]

We're translating an existing Java project that unfortunately has many uses of typeof as a Java variable name. It's easy enough for us to rename these but not as easy to prevent regressions in new code, since the pattern has been so widely used before.

Would it be reasonable to add a check for reserved words here and append an "_" if a variable name is found in an array of reserved words?

Want to check before going down this path to see if it's something you have considered in the past and whether there are any gotchas I should be aware of.

We already do a reserved words check as you describe, so all that's necessary is to add typeof to j2objc's reserved words list and rebuild the translator. Since the clang language extensions doc describes this and other standard mode-specific keywords, I'll add a new standard-mode section with all the current ones.

In the meantime, that clang doc suggests that you can avoid this by changing your Xcode project's C Language Dialect to any non-GNU standard, such as C11.

It turns out only typeof is missing, so a fix should be pushed out later today.

That's fantastic. Thank you so much!
