Re: Understanding regxp implementation
Nikolai, As you might know, the reg_comp() method is called twice when compiling a r.e; first to determine the size of the compiled expression and then to actually compile it. I was thinking if this can be used to our advantage, while on the first pass, we look for occurrences of special characters and set a flag in regprog_T appropriately. If such thing was not found, we branch off the second pass into one of our own routines to compile the expression into our own structures (say, a state diagram). And we have to change other functions a bit to look for the above flag and call new routines appropriately. What do you think ? - Asiri

Right, the main ftp server is in the Netherlands. All the rest are (cached) copies. I'm not a lawyer, but I would say that this means that the code isn't exported from the USA. It was already outside. I'm not sure about the CVS server at SourceForge. Generally I don't really care about these stupid US rules. The actual result is not that access to strong encryption by non-US contries decreases but that the development is done outside of the US, with the effect that knowledge outside of the US grows. -- TIM:Too late.

Re: Understanding regxp implementation
This mail bounced off for some reason, I'm repeating it. Sorry if you've already got this. - Hi Bram, Nikolai, All, I think the best way to understand current implementation of regxp is to first go through Henry Spencer's original regxp implementation ( thanks nikolai ). It's very compact and easy to mess with. After that, I think I would be able to come up with a hack to include new code into vim's regxp code base ( either TRE or our own implementation ). By the way, I have decided to apply for the GSoc ( I beleive I can crack this with the help of all of you ). I'm really greateful for the help provided by Nikolai and Bram, Thank you very much! ps : even if I'm not selected, I would still like to contribute to this project... :-) - Asiri
