[tools] modify fetch_languages.pl to only fetch a specific language

Patch status: applied Platform: all


In some cases, only a specific language is desired (and not all). The following is a patch to allow a --lang option to specify 1 language (i.e. --lang c99):

  • keywords languages added
  • patch set to rejected

I applied this patch in my sandbox and then called:

perl tools/dev/fetch_languages.pl bf

... which I subsequently realized was a mistake. I then called:

perl tools/dev/fetch_languages.pl lang=bf

In both cases, the program did not stop at bf. It proceeded to begin downloading c99 and all the other languages.

I infer that the patch cannot be applied as written. s1n, can you revise?

Thank you very much.

Changed 6 years ago by s1n

This tool uses Getopts::Long, so the correct way to call it would be something like

perl tools/dev/fetch_languages.pl --lang bf

I just tested that again and it functions properly.

Changed 6 years ago by s1n

I meant to say Getopt::Long. There may be other ways to properly interact, so see the  documentation.

  • status changed from new to closed
  • resolution set to fixed
  • patch changed from rejected to applied

Yes, it needs two hyphens before the lang=<hll>. That seems sane.

Thanks, applied as r39818. I took the liberty of updating the POD to reflect your changes.
