ExplicitNumberingPlugin

Use the ##., ##.. etc. notation to insert outline numbering sequences (1, 1.1, 2, 2.1) in topic's text.

Use ---#, ---##, etc., to generate numbered headings.

Syntax Rules

Numbered sequences

The default outline numbering sequence uses the notation ##... (with 1-6 dots). The notation is replaced anywhere in the topic. The level number corresponding to the number of dots increases with each use. Each time a level is used, all higher levels are reset to 0.
Named numbering sequences can be used with the notation ##name#... for sequence name. Named sequences have independent numbering.
The numbering of a sequence can be initialized or re-initialized by adding a number n into the tag. For example, ##name#2... resets numbering sequence name to 2. The sequence is initialized from the indicated level on.
- As a concession to backwards compatibility, 0 re-initializes the sequence at all levels. This comes in handy when using a sequence within headers that are also used in a %TOC%. In that case, start the first heading using something like ---+ Chapter ##0. Introduction. You can then safely use the number notation in headings.
The rendering of the numbering sequence can be turned into an letter-labeled list by appending a lowercase letter to the notation: ##...a

Numbered headings

When the + character in headings is replaced by #, the headings are numbered. Heading numbers are derived from the unnamed sequence and can, therefore, be affected by the syntax above.
- Tip: Avoid unnamed sequences when using numbered headings.

General comments

Numbering count is maintained throughout a single topic. Included topics are considered part of the topic and are numbered in sequence with the including topic.
The maximum number of levels is 6, and using levels higher than maximum implies the last level.
Non-consecutive increasing levels generate 0 for the skipped levels.
Sequence numbering always starts at level 1. A missing first level will result in a 0 to indicate the skipped level.
Non-numbered headers do not affect the numbering of numbered headings.

Examples

If you have the plugin installed, the Rendered and Expected columns should be identical. If you do not have the plugin installed, the Rendered column will be the same as the Source column.
