Hi, I am working on RCS file parsing. I had to do it cause I have 3,000 files with about 1 million revisions and I have to check them out one by one and collect information. Using existing Rcs module is very slow due to system calls to co for every revision. There is VCS::Rcs which I haven't tested but looks like it makes syscalls to 'co' too. Any way, what i do is to parse all the revisions into core and process them there. Which is about 10 times faster then using standart 'co' (or Rcs.pm). Ofcourse if you are talking about checking out atleast 20-25 revisions from the same revision file. The modules I wrote -for my own usage- are: XXX::Parser # this the main interface XXX::YappRcsParser # produced from a Yapp grammar (Yapp::Parse) XXX::Deltatext # impliments RCS deltatext algorithms Would you please suggest; 1- Shall I post them to CPAN, do you think others might use it? 2- If so, do you think RCS::Parser is a good name to use or not? Thank you, Ziya SuzenThread Next
