=== Comments ===
==== Comments ====
Separately from [[#block elements|block elements]] and [[#inline elements|inline elements]],
comments are another element available within vimwiki. There are two
classifications:
A special type of inline element is the comment. Compared to all other inline
elements, comments are unique in that they do not render into any other
format (HTML, PDF, etc) and - in the case of multi-line comments - can span
across more than one line.
There are two types of comments:
1. Line comment in the form of `%%CONTENT`
2. Multi-line comment in the form of `%%+CONTENT++%`
TODO ... if comments are removed from vimwiki before all other syntax is
evaluated, we need to provide an escape mechanism, otherwise the above syntax
within inline code will be removed when rendering to HTML, parsing, etc.
TODO ... while vimwiki, pandoc, and vimwiki server do not yet offer this, should
we consider an escape sequence to enable leaving a comment within a vimwiki
file as normal text. Something like `\%%` would leave as `%%` and `\%%+` would
leave as `%%+`. Could use the same conceal vim syntax as with bold and other
decorations to head the preceding backslash.
==== Line Comment Syntax ====
===== Line Comment Syntax =====
1. A *line comment* is represented by the following:
1. The sequence `%%`
2. Any character until [[#line ending|line ending]]
*Extra Notes*: A line comment does not consume a [[#line ending|line ending]],
only the characters leading up to one. If a line comment is at the beginning of
only the [[#character|characters]] leading up to one. If a line comment is at the beginning of
a line, it will leave a blank line in its place.
TODO ... today, the documentation describes a line comment as starting at the
beginning of a line while pandoc and vimwiki-server support a line comment at
any position in a line. What stance do we want to take here? Would we need a
compatibility layer for people who might have leveraged %% within the middle of
a line not expecting it to be a comment? Or should this be one of the advantages
of finally defining a specification in that we can avoid hard backwards
compatibility?
