User types specified as prefixes

[Thomas W. Barr]

I've inherited a large code base that I've been using indent to help 
clean up. It has a massive number of typedef'd types, though they all 
have a common prefix. I've patched the most recent version of indent to 
support a new command-line argument (--types-are-prefixes) that 
specifies that all user supplied types (passed with -T) are prefixes. It 
works wonderfully for my application.

If the developers would be interesting in accepting such a feature for 
future releases of GNU indent, I see three possible options. I will, of 
course, prepare a code and documentation patch for review and merging:

1) Accept the feature as is. It's only about a three line patch (except 
for handling the additional option).

2) Use fnmatch to support globbing in token names.

3) Support regex's for token names, using GNU libc's regex 
implementation. I'm not sure if this feature is present in all versions 
and architectures of GNU libc, so this may not be desirable.

Please let me know if you're interested,
