Hear ye, formalistic entity definition fans! |

Aforementioned evil project to interpret the PMS docs and recast them |
4 |
unofficially as a go-to formal grammar has advanced to its next stage of |
5 |
world domination! (Complete no-show by the forecast army of worker-gnomes |
6 |
notwithstanding.) |

As of a few minutes ago, thanks to some quirky ruby, almost-correct* |
9 |
regular expressions can now be generated for each of the various |
10 |
identifiers, which could be used in any tools. |
11 |
|
12 |
From a transparency/maintenance perspective it may be preferable to |
13 |
generate these for any package-related tools since it means everyone is |
14 |
sourcing their grammar - without error prone manual processes - from the |
15 |
same single point of truth, removing an entire class of bugs. |

* 'Almost correct' because entities like "a" are not officially allowed in |
24 |
ABNF, but desirable in spec for readability and ease of editing. An |
25 |
intermediate script is thus needed prior to regex generation to simply |
26 |
convert strings in to escaped entities ('%xxx' IIRC) to get properly solid |
27 |
output. Easy one but I'm otherwise disposed today. |
