These are some regular expressions I use for formatting purposes:
| Pattern | Replace by | Purpose |
|---|---|---|
^(?:\+|-|\x{2212})?(?:(?:\d{1,3}?(?:\,\d{3})*|\d+)\.?\d*|\d*\.?\d+)(?:[Ee][+-]?\d+)?$
|
N/A | Match a number |
(?<!(<\/\w+>[^\n]*)|\{|\})(?<=\n)(\||!)\s*(?!-|<\/\w+>|\{|\})
|
$1
|
Space out pipe characters and header separators in tables (one cell per line)* |
(?<!(?:<\/\w+>[^\n]*(?=<\/\w+>)|\{|\}))[^\S\r\n]*(\|\|\|?|!!!?)[^\S\r\n]*(?!-|[^\n]*<\/\w+>(?=<\/\w+>)|\{|\})
|
$1
|
Space out pipe characters and header separators in tables (entire row per line)* |
<math>,*\s*\\frac(\d)(\d),*\s*<\/math>
|
{{frac|$1|$2}} or{{sfrac|$1|$2}}
|
Standalone fractions with single-digit numerators and denominators can be done using {{frac}} or {{sfrac}} and don't need to be TeXified
|
* Requires support for variable-length lookaheads and lookbehinds
