Brilliant, thanks!

OK. I accept your suggestion.

Is --skip-unreadable OK for the option name?

Please tell me if you have better candidates.

If the --skip-unreadable option is specified, gtags does readable check

of source files before passing them to the parsers. The check is done using

access(path, R_OK).

If a file is unreadable, then gtags ignores it.

Ignoring means the followings:

(1) Print warning message.

(2) The file is not added to GPATH.

(3) The file is not passed to the parser.

Parsers are as before. Procedure die() and warning() are granted to

plug-in parsers. So, gtags cannot force them to continue the jobs.

But they will not stop their job because of permission error, because

such files are not passed.

What do you think?

Fair enough. That's why I am not asking to make this the default behavior, but either a config value or a command line option, which demotes the error&die to a warning.

(and something's gone wrong with skip, although it sounds like
that's impractical in this case, anyway)

It is impractical indeed. The skip rules would be huge and tedious to create in a trial and error approach.

In case of symbolic links, skip seems to look at the name of the link only, not at the name of the link target. In my scenario, if only one directory tree is unreadable, but is pointed to by a large number of links, I'd have to create skip rules for all these links.

Cheers
