# highr
[](https://travis-ci.org/yihui/highr)
This is an infrastructure R package for syntax highlighting. It supports
LaTeX and HTML output. Not surprisingly, it works best with R code. It
attaches markups onto source code, e.g., it turns
```r
a <- 1 # something
```
into LaTeX code
```latex
\hlstd{a} \hlkwb{<-} \hlnum{1} \hlcom{\# something}
```
or HTML code
```html
<span class="hl std">a</span> <span class="hl kwb"><-</span> <span class="hl num">1</span> <span class="hl com"># something</span>
```
via
```r
library(highr)
hi_latex("a <- 1 # something")
hi_html("a <- 1 # something")
# or hilight(code, format = "latex"/"html")
```
This package also has a wrapper function, `hi_andre()`, for Andre Simon's
[Highlight](http://www.andre-simon.de) package.
There are a few package Markdown vignettes in this package:
```r
browseVignettes(package = "highr")
```
To install the development version here, use
```r
install.packages('highr', repos = 'http://rforge.net', type = 'source')
```
This package is licensed under GPL, and is supposed to serve other packages
such as [**knitr**](http://yihui.name/knitr).
