Notepad++/Scintilla Lexer for R/Sweave files

RnwLang R/Sweave Syntax Highlighting for Notepad++

Rational

RnwLang is a project to serve two purposes. First to create a high quality Sweave syntax highlighter and code folding module, collectively referred to as a lexer. Second, to get a working template for Notepad++ compatible plugins that can be compiled with the GCC toolchain. I firmly believe in Free and Open Source software and it irks me that my favorite editor Notepad++ requires that to extendit you must use Microsoft's Visual C++ suite. I beleive that is antithetical to open source, and hope to help aleviate the restriction of using M$ products.

Sweave

Sweave is essentially two languages, TeX and R/S, where chunks of R code are embedded into a LaTeX document to provide reproducible report and article generation. In the current state a User must choose to use either the R lexer or the Latex lexer, which in my opinion could use some improvement. With RnwLang I hope to produce a Lexer that combines both and highlights appropriatly.

For building Sweave files I highly recommend Yihui's package knitr.

Building

I build with the TDM port of GCC which plays slightly nicer with the windows SDK, which is required or some components.

building should be as simple and going to the bin/ directory and executing make all UNICODE=1 for a unicode version. The --win32 flag might also be necessary. ANSI at this point is unsupported and untested.

npprnwlang's Issues

Consecutive code blocks do not fold correctly

Starting a new code block adds a level and does not terminate previous fold. Example:

<<code1>>=
x<-1
<<code2>>=
y<-1
@

brackets from different lines do not match

brackets, parentheses and braces from multiple lines do not match although they do on the same line.

Add Roxygen highlighting and create new R language lexer

Add new R language with these features:

1. Code folding for documentation/large comment blocks.
2. Highlight for Documentation.

Possibly should be named R Professional, or something similar.

Language panel show chinese

The language panel shows Chinese or Asian characters for Sweave Documents in the release version.

No Keywords in R code

R code does not highlight keywords.
