The Fortran Wiki and several on-line compiler documents and the standard provide descriptions of the Fortran intrinsics but none that I know of provide them as manpages;
which I strongly prefer for ease of access and integration into the programming environment on *nix systems. And I personally find the example programs in particular to be overly lacking in details (if they exist at all). So I just started a github site to create a set of manpages for the intrinsics.
I set it up to only require flat text files as input using the txt2man(1) markdown language
so anyone that would like to help does not need to learn *roff.
I threw in some bells and whistles so (assuming you are on a GNU/Linux, Unix, or CygWin environment) it automatically generates HTML versions from the manpages using groff(1) and an HTML index.
But if anyone thinks this is useful and wants to help it seems like using the txt2man(1) utility makes it easy for anyone to contribute (if I figure out how to allow contributes – still reading github documents :>).
I think I at least started one for each intrinsic. See
for release 0.0. If you have an urge to rewrite any of them please do so! Good code examples are needed in particular. If the bells and whistles do not work on your platform just change the text files in the doc/ directory and I’ll periodically build the *roff and html output files.
Once they seem complete and stable, maybe the *roff files could be distributed in other venues such as the Fortran stdlib project?
Seems like a simple and short community-driven project?
