# This file describes the style of user message formatting used by the current
# ACSIM frontend. ACSIM uses Markdown-esque formatting by default, but
# you can change it to any formatting type (if you can write regex correctly).

# The first string in the pair is an HTML template which defines the <span> or
# any other block formatted text will be placed in. Which text is picked
# is based on the names of regex match groups (see below). The second string is a
# regex that matches text by characters (such as ** or _) that enwrap it.

# Keep in mind that order of pairs matters! If messages are formatted
# incorrectly, try switching the order up. The recommended order is provided here.

---
# block quotes (greentext)
'${nl}<span class="quote">${text}</span>${nl}': '(^|(?<nl>\n))(?<text>>[^\n]+)'

# horizontal rules
'${nl_head}<hr>${nl_trail}': '(?<nl_head>\r(\s|\r)+)(?<hr_block>[\*|_|\-]{3})(?<nl_trail>\r(\s|\r)+)'

# headings. Markdown headings 3-6 are compressed into HTML's <h3>
'<h1>${head_text}</h1>': '(^|(\r(\s|\r)+))#\ (?<head_text>.+)(\r(\s|\r)+)'
'<h2>${head_text}</h2>': '(^|(\r(\s|\r)+))##\ (?<head_text>.+)(\r(\s|\r)+)'
'<h3>${head_text}</h3>': '(^|(\r(\s|\r)+))#{3,6}\ (?<head_text>.+)(\r(\s|\r)+)'

# 2+ and single newlines. 2+ newlines are collapsed into two
'<br><br>': '(\r(\s|\r)+)'
'<br>': '(\r(\s|\r){2,})'

# links to other messages and external websites
'<a target="_blank" rel="noopener noreferrer" class="msglink" href="/${board}/topic/${msg}#${submsg}">${board}>${msg}${dotted}</a>': '(?<board>\w{1,16})>(?<msg>\d+)(?<dotted>\.(?<submsg>\d+))?'
'<a target="_blank" rel="noopener noreferrer" href="${text}">${text}</a>': '(?<text>https?:\/\/[\w-]*?\.[a-z]{2,}(\/\S*)?)'

# misc text formatting
'<span class="codeblock">${text}</span>': '`(?<text>[^`]*)`'
'<span class="bold">${text}</span>': '\*\*(?<text>[^*]*)\*\*'
'<span class="italic">${text}</span>': '\*(?<text>[^*]*)\*'
'<span class="strikethrough">${text}</span>': '~~(?<text>[^~]*)~~'
'<span class="spoiler">${text}</span>': '\|\|(?<text>[^\|]*)\|\|'
