Yes, it almost certainly is and will get more dangerous when I add=20
font configuration etc., I'll correct the FAQ.

The ones shared by all users, i.e. installed in /var/lib/documancer=20
(or whatever) instead of ~/.documancer.

That's way too annoying.

OTOH, this makes sense.

I can see one case when it can happen quite frequently: when -devel=20
packages with documentation are upgraded on Linux.

Maybe it would suffice if we provide PDF-enabled config file with=20
Documancer? Even though I think this level of PDF support is not good=20
enough to be proud of it, I certainly won't stay in the way of having=20
at least some support!

I don't understand the question.

I think it will be much better to use Unix domain sockets instead.=20
It's more secure (if the permissions on socket are correct, only the=20
user who runs documancer can access it) and it doesn't have the=20
problem of finding the port number (the socket is in filesystem in=20
predermined location, e.g. ~/.documancer/socket-remote-control).=20
Win32 has some IPC mechanism that can be used instead (but it, sadly,=20
isn't wrapper by wxPython). I'd like to eventually get rid of having=20
to run HTTP server at all, for security reasons, but I need protocol=20
handlers support in wxMozilla for that first (it's on the way).

What I had in mind was a remote control server thread running in=20
Documancer (as you did it) plus a small documancer-remote program,=20
preferably written in C so that it has very little startup overhead=20
and new instance of it can be launched for every request (so that =20
you can simply bind a shortcut in Vim to launching specific=20
documancer-remote command and get instant response). This small=20
program would do no real job, it would only route requests to=20
Documancer server (it wouldn't even have to parse its command line,=20
it could send it as-is) and to launch Documancer if no instance is=20
running yet.

Ideally you should be able to run, say, "documancer-remote=20
=2D-list-books", which would be sent to the real Documancer and its=20
output would then go to stdout, w/o having to worry about parsing=20
config.ini in the remote controller.

=2E..which is *very* useful in itself! You're helping me a lot with=20
clever complains ;) and suggestions, so thanks for that!
