That's probably the reason why I really can't have much for a choice.

I have test scripts but I didn't include it in the package. It's not really necessary to include them I guess.

If you are serious about optimizing I would go back to my earlier suggestion: rewrite the program to handle multiple paths per run, perhaps using a fifo or socket.

Probably but I'm not sure if that's really applicable since no part of the code requires more than 1 path at a time.

I'm wondering why you have a hashing function in your compiler, aren't all awk arrays hash tables already?

Do you mean makehash()? I just use it to create hashes like the ones created by md5sum and the likes. I use it to create functions that will represent call files.

By the way I finally finished the Simpler version as well. Loader-Simpler includes the extended functions loadx(), includex() and callx(). They acknowledge patterns and expressions.

The last will be the full and non-stripped version but it's the most difficult and surely it will not be soon.. though.

I think I know now what you mean but I think it would be better if I put that on a different package since it appears to be more like a hack and I'm not sure if it will be stable as a generic implementation for shells.

Um, I can't parse this sentence.

But you have some example that runs slow (which is why you asked for optimization help), right? It would be interesting to see that.

About the scripts? Not really. I'm pretty happy with what they are right now and they appear to be already stable and consistent. After many revisions, I finally found their final form (probably the most optimized and most balanced form). And nothing has changed much since the first release (only descriptions and documents except for the generic loader where I didn't test its failure function).

But of course and nevertheless, I can never be sure of that and suggestions like yours (esp. from someone that helped me a lot already) will always be welcomed.

Just made the cleaner version of the test scripts and uploaded them. Same site at sourceforge in the extra folder. Good luck and enjoy

I just made a new upload of my other project. The project uses ShellScript Loader and I just thought that you might also want to see how it proves the concept.

old thread but you are assuming the path seperator is "/" but in dos and windows its "\";

yes, it's only meant for the *NIX format..
