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*((?:[^\s=]+\s*)+[^\s=])\s*(=+)or (?<=\n)(\=+)\s*((?:[^\s\=]+\s*)+[^\s\=])\s*(\=+)
|
$1 $2 $3
|
Space out equals signs for section headers* |
(?<=\n)(\||!)(?!-)[^\S\r\n]*(?!\}|\+)
|
$1
|
Space out pipe characters and header separators in tables (one cell per line)* |
(?<=\n)(\||!)[^\S\r\n]*\|?[^\S\r\n]*(?!-|\}|\+)
|

(\d+[Ll])\s*(\d+[Ss])
|
$1 $2

(?<!(?:<(\w+-)*\w+>[^\n]*(?=<\/(\w+-)*\w+>)|\{|\}))[^\S\r\n]*(\|\|\|?|!!!?)[^\S\r\n]*(?!-|[^\n]*<\/(\w+-)*\w+>(?=<(\w+-)*\w+>)|\{|\})
