This is for making PDFs using C# code, right? And you can preview it while you work? I was wondering if that is available for other programming languages.
Since you mention Forth, I might mention that PostScript is another stack-based programming language (different than Forth although there are some similarities), which can be used to make PDF output. Additional PostScript codes could be made which you can load into your file in order to add additional procedures, etc for doing formatting that you will not need to write by yourself.
I don't care about Karma at all, I really was just trying to ask a question. I'm interested in learning HTML and CSS. I'm also interested in creating PDFS. My question was since this looks like it's for making PDFs using C# code, and you can preview it while you work, I was wondering if that is available for other programming languages. Besides HTML and CSS, someday I want to learn C and FORTH. I thought this would be a practical way to get familiar with programming languages.
