# goldmark-qjs-katex | ||
|
||
This is an extension for [Goldmark](https://github.com/yuin/goldmark) that adds TeX rendering using KaTeX. It embeds QuickJS and QuickJS-compiled KaTeX bytecode. | ||
|
||
The parser follows pandoc's rules for TeX in markdown. Right now, `$` and `$$` are the only supported delimiters. Also, only KaTeX's default configuration is supported. | ||
|
||
### Performance | ||
|
||
``` | ||
goos: windows | ||
goarch: amd64 | ||
pkg: github.com/graemephi/goldmark-qjs-katex | ||
BenchmarkSequencesAndSeries/NoKaTeX-4 12210 981796 ns/op 381171 B/op 1497 allocs/op | ||
BenchmarkSequencesAndSeries/NoCache-4 10 1069105530 ns/op 4900488 B/op 1563 allocs/op | ||
BenchmarkSequencesAndSeries/Cache-4 5041 2329294 ns/op 4443003 B/op 1545 allocs/op | ||
``` | ||
|
||
## Usage | ||
|
||
``` | ||
import "github.com/graemephi/goldmark-qjs-katex" | ||
``` | ||
``` | ||
markdown := goldmark.New( | ||
goldmark.WithExtensions(&qjskatex.Extension{}), | ||
) | ||
``` | ||
|
||
Also, godoc. | ||
|
||
## Building | ||
|
||
If you just want to build, gcc must be installed, and all you need to do is | ||
|
||
``` | ||
go build | ||
``` | ||
|
||
However, if you modify `./katex/katex.js`, then you must recompile the JS source to bytecode with qjsc. qjsc can be compiled from source in `./katex/quickjs/`. In addition, if these modifications change the way TeX is rendered then you need to regenerate the test cases. This requires pandoc to be installed. Run | ||
|
||
``` | ||
make | ||
``` | ||
to do all that, or look in the Makefile to see how to do it. | ||
|
