Additional language: Forth

[larsbrinkhoff]

File extensions: 4th, f, for, forth, fr, frt, fth, fs. These are supported by GitHub's Linguist.

Comments:

• \ to end of line.
• ( to ) on same line.
• (* starts a multi-line comment ending with *).

Note that the token starting the comment must be surrounded by whitespace.

Rare file extensions: 4, blk, f83, fb, fpm, ft, rx, scr, spf, txt, e4.

I guess you can ignore txt.

I added support for Forth with many (4th, e4, f83, fb, forth, fpm, fr, frt, ft, fth, rx) of the listed extensions with git commit 121cc5e.

These extensions conflict with Fortran: f, for
This extension conflicts with F#: fs
These extensions (like txt) map to non-code files I'm familiar with: scr, spf

cloc can work with extensions to map to multiple languages but then more work is needed to write a special function that can deduce which of the two or more languages a given file is. I might revisit that in the future. Or you could supply the function (see for inspiration cloc's existing subroutines matlab_or_objective_C(), pascal_or_puppet(), Perl_or_Prolog(), et cetera).

Thank you!

scr is just Forth source code without line breaks. That's why they look strange.

[AlDanial]

The integration of your two routines is complete with git commit 88f71e7.

[larsbrinkhoff]

Looks good!

hi Lars, if you have a moment could you respond to the remarks at #103 regarding the use of (* .. *) to denote Forth comments?

[larsbrinkhoff]

Yep.
