There is already another plugin which does just that: Comment. The only difference is the markup, /* hidden comment */ as in many programming languages. — Esther Brunner 2005-12-14 16:33

Oups sorry, that's right :) i didn't see it :/

I cannot get this to work in DokuWiki-2005-09-22. The complete comment, plus the surrounding tags, is visible on the page. (I cannot get Hidden Comment to work either.) — Chris Lale 2005-12-15 13:53

You say in the instructions to use != and =! for comments when it should be !- and -!

Hi. I propose the fix of A. This patch has the following effects.

1. plugin_commentsrc can use !- -! besides /* */.
2. Two or more comments can be used in one page. (The released version was able to use only one comment in one page. )

I like this plugin because the light weight.

Kohei is right. The .* part in the pattern "!-.*-!" would eat as much as possible, thus eating the text between two comments:

!- comment -! Disappearing text !- comment again -!

Esther's plugin is using .*? which matches “as little as possible”. This is (i think) equivalent to Kohei's solution with entrypattern and exitpattern. — 2

I patched it (by hand) with Kohei MATSUSHITA's notes (didn't get Esther 'comment' plugin working), and I used "[^A-Za-z0-9_-]/\*" instead of ”/\*” because I noticed some problems with some texts like: “rm /some/folder/*” where '/*' should not be seen as the start of a piece of hidden text; still got some problems with two lines below eachother having only /* comment */ on them
