does any body know anything about parser generator?

you can use it some of php or java script if your not familar with coding you can use it tickermyfeed.com/\n\nor you can get more deatils in dynamicdrive.com

Well, I can't advise you from experience, but I know of a website that has all sorts of resources for programming for free.  The URL below has free compilers, IDEs, tutorials, articles and other programming tools for a lot of different languages and platforms.  Take a look and I'd bet even odds you'll find some things to help you out.  Good Luck!

Try Babelfish. But, like all machine translators, it's a machine.

Top-down parsing - A parser can start with the start symbol and try to transform it to the input. Intuitively, the parser starts from the largest elements and breaks them down into incrementally smaller parts. LL parsers are examples of top-down parsers. \n\nBottom-up parsing - A parser can start with the input and attempt to rewrite it to the start symbol. Intuitively, the parser attempts to locate the most basic elements, then the elements containing these, and so on. LR parsers are examples of bottom-up parsers\n\nExamples of parsers:\n\nTop-down parsers\nSome of the parsers that use top-down parsing include:\nRecursive descent parser \nLL parser \nPackrat parser \nUnger parser \n\nBottom-up parsers\nSome of the parsers that use bottom-up parsing include:\nprecedence parsing \nBC (bounded context) parsing \nLR parser \nSLR parser \nLALR parser \nCanonical LR parser \nGLR parser \nEarley parser \nCYK parser

Don't you know?\nDid you get the grammar wrong (if so congrats)\nIs this code for something?

use the cacls command.\n\nStart > Run > CACLS /?\n\nThe above command will display the help and file syntax.

Hi spaceman! :O)\n\nI've tried a few.  One I would reccomend to you would be at http://open-perl-ide.sourceforge.net/ . It's a free Perl IDE w/ highlighting :O)  You can also find a similiar editor at http://www.indigostar.com/perledit.html&e=912\n\nIf you are comfortable with the IDE from Visual Studio, it may be nice to check out http://www.activestate.com/Products/Visual_Perl/ - This does include a classes/objects/etc. tree too :O)\n\nhttp://user.bahnhof.se/~johanl/perl/Oasis/ is a program which will help you navigate through your classes/subroutines through a tree too. :O)\n\nI hope one of these can help you.. :O) Good luck!

Perl is free. Visit perl.org and get it.

You will need a div command. If you go to about.com and search for "DIV". I would try to paste it in here, but the parser will eat it alive. From any website, you can view source to see the code that creates what you see. If you need more help, email me and I'll send you some samples...\n\nGood Luck!

There's more to lexical analysis and LR parsing than I'm\nwilling to try to cover in a Yahoo Answers question.\n\nHowever, "Lex" is a lexical analyzer -- which means that\nit takes an input stream of characters and breaks it up into\ntokens. For a programming language, the tokens would be\nkeywords, operators, numbers, strings, variable names, etc.\n\nIt's a finite state machine driven by regular expressions,\nfor example:\n\n[a-zA-Z][a-zA-Z0-9]*  { return STRING; }\n\nwould mean:\n[a-zA-z] -- match exactly one character in ranges a-z or A-Z\n[a-zA-Z0-9]* -- match 0 or more chars of lower, upper, or numeric\n\nMaybe the best way to understand this is to look at some\nexamples.  There are *many* on the net, and I've listed\na few (below) which were directly taken from a search\nengine listing.\n\nYACC is more complicated, but it's job is to take\nan input stream of tokens (ie. from a Lex-generated\nlexical analyzer) and parse that based on a grammar.\n\nShort of providing a couple of weeks of course work\non the theory of grammars :-), I can at least point\nout that reference #1 contains some very short\nexamples of both lex and yacc files to implement\na simple calculator.

I prefer simple and use webalizer.  But if you're looking to do it yourself, the perl module Apache::ParseLog (available on CPAN) is useful and includes examples.  PHP probably isn't as good a choice as perl or python.
