Post Processor coding

[byte me 648]

Hi all,

I've been practicing the post processing writing a bit this weekend.

I noticed the user defined names in the posts I see are a bit unclear as to what they do a lot of shortened names,

For my posts that I'm writing I think I might use a camel case like we do for the chook and nethook programming.

In the following example the user defines variables are written like this

stringOpenParentheses    : "("   #String for open parenthesis "("
stringCloseParentheses   : ")"   #String for close parenthesis ")"
stringDelimiter   : "|"   #String for delimiter 

I think that makes it more clear to the end user what everything does. JM2c

If a variable has a $ at the end, it's a system variable and that name cannot be changed

Those of us who have dug around in posts for awhile know what the other variables are...

If you were going to write your own post engine, yeah I can see it...if you're modding existing posts, it probably doesn't make a lot of sense to rewrite a huge portion of what already works.

Yeah I knew that going in, I was purely speaking on the User Defined varables.

Yeah I was thinking more for new posts, updating existing posts using find and replace could be error prone..
