Observed behavior:

When I create a link like [[cmd_test]] , the link appears as 'cmd test'.

Expected behavior:

I would like to be able to create links with underscores. I realize this is a feature, and I searched for ways to escape the underscore so it would appear, but I didn't find any.

as a workaround, you can use [[cmd__95__test|cmd_test]] (which will link to a page named "cmd test" at the url location "cmd_test") or [[cmd__95__test]] (which will link to a page named "cmd_test" at the url location "cmd__95__test"). i would, from my limited understanding of ikiwiki internals, consider the bug valid, and suggest that

• explicit link text be not subject to de-escaping (why should it; this would be the short term solution)
• escaped page names never be used in user visible parts of ikiwiki (in my opinion, a user should not need to know about those internals, especially as they are configuration dependant (wiki_file_regexp))

note that in wikilink, that very behavior is documented; it says that "[[foo_bar|Sandbox]]" will show as "foo bar". (although you can't tell that apart from "foo_bar" easily because it's a hyperlink).

i assume that this behavior stems from times when wikilinks and directives were not distinguished by [[ vs [[! but by the use of whitespace in directives, so whitespace had to be avoided in wikilinks.

having hacked around in the link plugin, i can confirm that the link texts are explicitly de-escaped, and that when no pipe is inside the link (ie links like [[cmd_test]]), the string "cmd_test" is regarded as a link (that will subsequently be converted to a readable text) rather than as a readable text (for which a suitable link target is found automatically). --chrysn
