# shr-tag-pre-highlight - Syntax highlighting code block in HTML
*Author:* Chunyang Xu
*Version:* 2[![MELPA](https://melpa.org/packages/shr-tag-pre-highlight-badge.svg)](https://melpa.org/#/shr-tag-pre-highlight)
This package adds syntax highlighting support for code block in
HTML, rendered by `shr.el`. The probably most famous user of
`shr.el` is EWW (the Emacs Web Wowser).### Example
| Before | After |
| ------ | ----- |
| ![](eww-default.png) | ![](eww-with-syntax-highlighting.png) |In above, I am using EWW to visit
https://emacs-china.org/t/eww/2949. And the color theme is
sanityinc-tomorrow-eighties, from Steve Purcell's
color-theme-sanityinc-tomorrow package## Installation
This package is available from MELPA. If you use
[use-package](https://github.com/jwiegley/use-package) to manage the init
file, use something like the following:(use-package shr-tag-pre-highlight
:ensure t
:after shr
:config
(add-to-list 'shr-external-rendering-functions
'(pre . shr-tag-pre-highlight))
(when (version< emacs-version "26")
(with-eval-after-load 'eww
(advice-add 'eww-display-html :around
'eww-display-html--override-shr-external-rendering-functions))))## Why is `eww-display-html` advised for Emacs version older than 26
Unfortunately, EWW always overrides
`shr-external-rendering-functions` until
[this commit](http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=45ebbc0301c8514a5f3215f45981c787cb26f915)
(2015-12), but Emacs 25.2 (latest release - 2017-4) doesn't include
this commit. Thus if you want syntax highlighting in EWW, you have
to use devel version of Emacs (also know as emacs-26 at this
moment) or advice `eww-display-html` as above.---
