Wyatt Allen db8691a96b Remove styles for markdown syntax

Support for markdown files would only typeset text as bold or italic
when it appeared inside the corresponding inline Markdown syntax. It
didn't render the Markdown, but rather approximated what the text might
look like if rendered. Because this provides little real value, and
because HLJS sometimes incorrectly parses these Markdown constructs,
markdown is dropped from the highlighting layer.

Building Highlight.js for Gerrit

Highlight JS needs to be built with specific language support. Here are the steps to build the minified file that appears here.

NOTE: If you are adding support for a language to Highlight.js make sure to add it to the list of languages in the build command below.

Prerequisites

You will need:

nodejs
closure-compiler
git

Steps to Create the Pack File

The packed version of Highlight.js is an un-minified JS file with all of the languages included. Build it with the following:

$>  # start in some temp directory
$>  git clone https://github.com/isagalaev/highlight.js.git
$>  cd highlight.js
$>  node tools/build.js -n \
      bash \
      cpp \
      cs \
      clojure \
      css \
      d \
      dart \
      erb \
      go \
      haskell \
      java \
      javascript \
      json \
      kotlin \
      lisp \
      lua \
      objectivec \
      ocaml \
      perl \
      php \
      protobuf \
      puppet \
      python \
      ruby \
      rust \
      scala \
      shell \
      sql \
      swift \
      typescript \
      xml \
      yaml

The resulting JS file will appear in the "build" directory of the Highlight.js repo under the name "highlight.pack.js".

Minification

Minify the file using closure-compiler using the command below. (Modify /path/to with the path to your compiler jar.)

$>  java -jar /path/to/closure-compiler.jar \
        --js build/highlight.pack.js \
        --js_output_file build/highlight.min.js

Copy the header comment that appears on the first line of build/highlight.pack.js and add it to the start of build/highlight.min.js.

Finish

Copy the resulting build/highlight.min.js file to lib/highlightjs
