i would like too create a scripting language. which is extremely easy. but i want something that can interpret it. does anyone know the code to make a browser that only will browse my scriptin language and display them on the screen?
P.S.:i am extremely new to xml or sgml so bear with me :eek:

wooh I don't know of any tools that could be used to write a "easy" scripting language and interpreter. It depends on how advanced the things you want to do with it. I.e. If you want a secure login system that interacts with a MySQL database (if your language was supported by it) then you would have to write a lot of code just to make it secure.

If you want to do really simple things with it, then it *might* be possible to create something like java I should think but writing a interpreter to run and display the output code correctly as html would be a bit hard to do. I know PHP is one of the fastest-developed scripting languages but it does have some really powerful, hectic features that allow coders to create powerful programs.

However, I haven't done any research into this before, so I might have a look into the posibility.

As for a browser, then you would have to write it in a language that Windows could read, execute and interpret such as C/C++. You would then have to write a interpreter within the browser after coding the UI, features, functions and such like....The interpreter would interpret the output code from the server and would display it in the browser window...However it would mean a lot of work..

thanks but im thinking of java to send the data and read it out then display it on a frame, i am not thinking of making it a common scripting language but one that would be easy to change and modify. i hope i am not sounding like a n00b though. i am a noob to this not a n00b :thumbsup: plus does anyone know the snippet for java to use 1.fileinputstream2.scan the file for known script or code3.organize the rest of the data inside of the code4.display on jframe...i know this is a lot to ask so any help is appreciated:)

and for the first post i meant that thinkin up the code items would be easy...not the browser+interpretor :)

Can you give us some samples of what you want to do?

this has enough browsing functionality for me to work with. but i want to be able to configure theoutput on the page when a specific command such as "<bold>hi</bold>"would result in hi as you can see what i mean. i am trying to make a language for my own use that would resemble html but with features such as connecting to a port and writing files and so such. but my problem is i need to find a way to do these commands. all the best. PS:Jose M. Vidal made the layout of this so thanks if youre reading this:)
