batch to bash translation

[foundation]

Hi

I wanted to share a project of mine here.

I was working on it as a part of compilers class exam.

It is a windows batch script to bash translator

you can see it here http://ea.github.com/batch2bash/

i know the project itself might be pointless , but since xkcd forums have wide range of users
with wide range of interests , it looked like a good idea to post it here
i had a great trouble finding something similar, there isn't anything

it's written in a combination of c and c++ , mostly c++
it's using bison and flex for parsing

the most valuable in this project could be the grammar of batch scripts , which i was unable to find anywhere , so i'm posting this topic so that anybody who needs it in the future could find it via google

of course , the grammar is incomplete, as is the translation, but it handles things pretty well

cheers , ea

looks good

There are a few flaws ("@ECHO OFF" actually echos "off" and it has problems with absolute paths beginning with "C:/"), but it seems to work pretty well with the example batch files I looked up.

well, right now the grammar is pretty hacked up , it will probablly have some changes
when we get some time to work on it again
batch grammar is really tricky, no formal specification so we basically reverse engineered it

Just for those who accidentally stumble across this in google while searching on how to do this automatically...
it doesn't work.
TO save you some time compiling, it doesn't work. Okay? Errors out on every single script I've thrown at it.
