Re: [photran] Refactoring for Fortran code with #include?

Managing this complex software with an IDE would be extremely helpful, but the IDE support for complex Fortran (i.e. free-form, with script-generated code inserted with CPP directives) has traditionally been absent.

It looked, at first glance, like all refactoring operations are disabled for Fortran source with C preprocessor directives. Since most of the WRF software has these directives, which inserts automatically generated Fortran code sometimes in excess of 10,000 lines, it would seem l am still out of luck as far as using Eclipse/Photran to manage and try to control its ever-growing gnarliness.

One example: we don't want users writing debug messages directly to various output streams, but call one of our debug message handling functions instead. We would like Fortran lines of the form

I can't answer to your question about CCP directives.
About mange complex code, I'm developing fortran code not large as your code but it is about 100000 lines.
The use of Eclipse/Photran works very well and I'm really appreciate it, although, I've encountered several problems relatively to the size of the code/files :
- I don't find convenient to work with large files (more than several thousand lines), but it is OK.
- Unfortunately, I can't use refactoring (I've to disable it). I've had several "internal error" and I've had to "rebuilt the database" often. The worst is to save a file which can take ages (sometimes several minutes).
Every new version of Eclipse/Photran, I'm trying "the refactoring feature", but I don't see improvement.
Best regards
David
