So this is the current one-
http://www.thehelper.net/forums/showthread.php?t=140936
I don't like it... for example, it's many isType and getType methods irritate me and the fact that it couples up the parser and the command manager just seems like an extremely poor design to me >.<..
So, I've been working on a 2 part project-
parser (highly customizable) (done)
command framework (support for different shells and etc)
The parser includes a string stack object that will automatically split a string up into a stack given a delimhttp://www.thehelper.net/forums/forumdisplay.php?f=109iter, a typeof to automatically infer the data type of a given string ('' is treated as ascii and rest are inferred based upon the values). For the most part, types fit into other types. For example, an integer can be treated as a real or a string (follows this hierarchy on data types).
names can also be printed given a type id
The typeof method automatically infers types (as I said above)
Obviously I'm still going to be doing some more stuff, but this is how I believe a Parser should be designed ; |. CommandParser is designed in such a way that I refuse to use it, lol.
also, I'm going to do different build strings for the StringStack struct (single argument builds for ripping specific types out of the string and etc).
example of use (with just the parser) (I know I have a ton of extra locals, lol) (uses default delimiter on the StringStack creation)
ripper code
for single argument commands (provides more flexibility)
and how you might use the above
