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 |
(?<=\n)(=+)\s*([^\|\{\}\r\n=]*)\s*(=+)(?=\n)or (?<=\n)(\=+)\s*([^\|\{\}\r\n\=]*)\s*(\=+)(?=\n)
|
$1 $2 $3
|
Space out equals signs for section headers* |
(?<=\n)(\||!)[^\S\r\n]*\|?[^\S\r\n]*(?!-|\}|\+)
|
$1
|
Space out pipe characters and header separators in tables (one cell per line) Replace ! | and | | with ! and | , respectively
|
(?<=\{\|.*?\n)(?<!\|-\n)(\||!)
|
|-\n$1
|
Insert table cell separator at top of table before first headers |
(\d+[Ll])\s*(\d+[Ss])
|
$1 $2
|
Make sure xL ys notation for MOS scales are non-wrapped |
(\d+[Ll])\s*(\d+[Mm])\s*(\d+[Ss])
|
$1 $2 $3
| |
(?<=(?:colspan|rowspan|id|scope|style)="?.*?"?)[^\S\r\n]*(?<![Ff]ile.*?)((?:\||!){1,3})[^\S\r\n]*
|
$1
|
Space out inline cell separators* |
(?<!\n|\{)[^\S\r\n]*(?<![Ff]ile.*?)((?:\||!){1,3})[^\S\r\n]*
| ||
(?<=\n)((?:\*|:)+)\s*
|
$1
|
Space out |
<math>,*\s*\\frac(\d)(\d),*\s*<\/math>
|
{{frac|$1|$2}} or{{sfrac|$1|$2}}
|
Standalone fractions with single-digit numerators and denominators don't need to be TeXified |
* Requires support for variable-width lookaheads and lookbehinds
