hVmark

hVmark is a tiny, opinionated markup language made by and for, well, me. While it's used all over this website, it's primarily used in posts in lieu of hard-coded HTML.

// Inline Markers

Block Formatting

• Center Text: &text&
  Wraps line in <center> tag.

Text Formatting

• Bold: *text*
• Emphasis (Italics): /text/
  Alternate: %text%
• Strike: -text-
• Underline: _text_
• Code: `text`

Misc.

• Soft line break: [] -> <br>
• Horizontal rule: --- -> <hr>
  Three or more -, *, or _ characters on their own line will output a horizontal rule.
  Output styling depends on configuration.
• Subheading: *// Subheading Text*
• Subheading output: <h# id="subheading-text">// Subheading Text</h#>
  Actual heading level is based on config.
• Optional TOC: If two or more subheadings are found, a table of contents will be generated. The TOC is automatically placed under the main heading (<h1>) of the page, at the top of the page if a main heading isn't present, or at the location of
  <!--HV_TOC-->.

// Links, Images, YouTube

All use the same “anchor + fangs” pattern: @@anchor^fangs^

• Links: @@https://example.com/^Link text^
  (leave fangs empty to use the URL as text, e.g. @@https://example.com/^^)
• Images: @@img:/path/file.jpg^Caption^ (85% width by default; caption optional)
  Full: @@img:/path/file.jpg[50px|25% left|right|center|blank]^Caption^
• YouTube: @@ytb:VIDEOID^Caption^ (caption optional)

// Lists

• Dotted: one item per line starting with [+]
• Plain: one item per line starting with [-]
• Soft breaks are allowed inside items via []

// Notes & Quirks

• Order matters when nesting: * and % are forgiving, but consistent nesting is recommended.
• Inline raw HTML on a line disables hVmark parsing on that line.
• A backslash will escape an inline marker and output the literal symbol.
  (e.g., \% will output %.)
• Despite the above, the symbols used for inline markers do not appear in the alt text of images, escaped or not.
• Emojis are supported in regular text, but not in subheadings.
• Subheadings with similar names will have duplicate IDs; the TOC generator does not add incrementing suffixes.
• Blockquotes are not currently part of v1.
