Adicionei um hook ao nosso código HighlightJS, então agora você pode usar a API de plugin para adicionar uma linguagem personalizada para o Highlight.JS.
Exemplo (usando a definição de linguagem beancount):
const beancountLang = function(e){var c=\"[A-Z][A-Za-z0-9-]*\",a=\"[0-9]{4}[-|/][0-9]{2}[-|/][0-9]{2}\",b=\"(balance|commodity|document|event|note|open|pad|price|query)\",t={cN:\"literal\",b:/([\\-|\\+]?)([\\d]+[\\.]?[\\d]*)/,r:0},n={cN:\"string\",b:'\"',e:'\"',r:0,c:[e.BE]},s={cN:\"name\",b:\"\\\\{\",e:\"\\\\}\",c:[{cN:\"literal\",b:a},t,n,{cN:\"subst\",b:\"[A-Z][A-Z0-9'._-]{0,22}[A-Z0-9]\"}]};return{aliases:[\"beancount\",\"bean\",\"ledger\"],c:[{cN:\"built_in\",b:\"^(include|option|plugin|popmeta|poptag|pushmeta|pushtag)\",r:0},{b:\"^\"+a+\"\\\\s+\"+b,rB:!0,r:10,c:[{cN:\"type\",b:a,e:/\\s+/,eE:!0},{cN:\"keyword\",b:b}]},{b:\"^\"+a+\"\\\\s+.\\\\s\",rB:!0,r:10,c:[{cN:\"type\",b:a,e:\"\\\\s+\",eE:!0},{cN:\"variable\",b:\".\",endsParent:!0}]},e.C(\";\",\"$\"),{cN:\"meta\",b:/^\\s{2,}[a-z][A-Za-z0-9\\-_]+:/},s,{cN:\"name\",b:\"@\"},{cN:\"type\",b:c+\":\",r:0,c:[{cN:\"subst\",b:c+\"(:\"+c+\")?\"}]},{cN:\"section\",b:/^\\*\\s+?.*/},{cN:\"link\",b:/\\^[A-Za-z0-9\\-_\\/.]+/},{cN:[\"emphasis\"],b:/#[A-Za-z0-9\\-_\\/.]+/},n,t]}}\napi.registerHighlightJSLanguage(\"beancount\", beancountLang);\n```
