Insane start at any of the recognized protocols are the ones shown at: Section "Known URL protocols".
  • http://
  • https://
absolutely anywhere if not escaped, e.g.:
ahttp://example.com
renders something like:
a <a href="http://example.com">
To prevent expansion, you have to escape the protocol with a backslash \\, e.g.:
\http://example.com
Empty domains like:
http://
don't becomes links however. But this one does:
http://a
Insane links end when any insane link termination character is found.
As a consequence, to have an insane link followed immediately by a punctuation like a period you should use an empty argument as in:
Check out this website: http://example.com[].
which renders as:
Check out this website: example.com.
otherwise the punctuation will go in it. Another common use case is:
As mentioned on the tutorial (http://example.com[see this link]).
which renders as:
As mentioned on the tutorial (see this link).
If you want your link to include one of the terminating characters, e.g. ], all characters can be escaped with a backslash, e.g.:
Hello http://example.com/\]a\}b\\c\ d world.
which renders as:
Note that the http://example.com inside \a[http://example.com] only works because we do some post-processing magic that prevents its expansion, otherwise the link would expand twice:
\P[http://example.com]

\a[http://example.com]
which renders as:
This magic can be observed with --help-macros by seeing that the href argument of the a macro has the property:
"elide_link_only": true,
