Seems like there should be a page for you to post your thoughts about
ikiwiki, both pro and con, anything that didn't work, ideas, or whatever.
Do so here..

Note that for more formal bug reports or todo items, you can also edit the
[[bugs]] and [[todo]] pages.

# Installation/Setup questions

Ikiwiki creates a .ikiwiki directory in my wikiwc working directory. Should I
"svn add .ikiwiki" or add it to svn:ignore?

Is there an easy way to log via e-mail to some webmaster address, instead
of via syslog?

# Upgrade steps

I upgrades from 1.37 to 2.6.1. I ran "ikiwiki --setup" using my existing ikiwiki.setup configuration.
I had many errors like:

    /home/bsdwiki/www/wiki/wikilink/index.html independently created, not overwriting with version from wikilink
    BEGIN failed--compilation aborted at (eval 5) line 129.

and:

    failed renaming /home/bsdwiki/www/wiki/smileys.ikiwiki-new to /home/bsdwiki/www/wiki/smileys: Is a directory
    BEGIN failed--compilation aborted at (eval 5) line 129.

Probably about six errors like this. I worked around this by removing the files and directories it complained about.
Finally it finished.

My next problem was that ikiwiki start letting me edit without any password authentication. It used to prompt
me for a password but now just goes right into the "editing" mode.
The release notes for 2.0 say password auth is still on by default.

> It sounds like you have the anonok plugin enabled?

The third problem is that when editing my textbox is empty -- no content.

This is using my custom rcs.pm which has been used thousands of times.

Now I regenerated my ikiwiki.cgi again (no change to my configuration,
and I just get an empty HTML page when attempting editing or "create".

Now I see it created directories for my data. I fixed that by setting 
usedirs (I see that is in the release notes for 2.0) and rerunning ikiwiki --setup
but I still have empty pages for editing (no textbox no html at all).

(I am posting this now, but will do some research and post some more.)

Is there any webpage with upgrade steps?

--JeremyReed

My followup: I used a new ikiwiki.setup based on the latest version. But no changes for me.

Also I forgot to mention that do=recentchanges works good for me. It uses my 
rcs_recentchanges in my rcs perl module.

The do=prefs does nothing though -- just a blank webpage.

I also set verbose => 1 and running ikiwiki --setup was verbose, but no changes in running CGI.
I was hoping for some output.

I am guessing that my rcs perl module stopped working on the upgrade. I didn't notice any release notes
on changes to revision control modules. Has something changed? I will also look.

# Excellent - how do I translate a TWiki site?

I just discovered ikiwiki quite by chance, I was looking for a console/terminal
menu system and found pdmenu.  So pdmenu brought me to here and I've found ikiwiki!
It looks as if it's just what I've been wanting for a long time.  I wanted something
to create mostly text web pages which, as far as possible, have source which is human 
readable or at least in a standard format.  ikiwiki does this twice over by using 
markdown for the source and producing static HTML from it.

I'm currently using TWiki and have a fair number of pages in that format, does
anyone have any bright ideas for translating?  I can knock up awk scripts fairly
easily, perl is possible (but I'm not strong in perl).

> Let us know if you come up with something to transition from the other
> format. Another option would be writing a ikiwiki plugin to support the
> TWiki format. --[[Joey]]

> Jamey Sharp and I have a set of scripts in progress to convert other wikis to ikiwiki, including history, so that we can migrate a few of our wikis.  We already have support for migrating MoinMoin wikis to ikiwiki, including conversion of the entire history to Git.  We used this to convert the [XCB wiki](http://xcb.freedesktop.org/wiki/) to ikiwiki; until we finalize the conversion and put the new wiki in place of the old one, you can browse the converted result at <http://xcb.freedesktop.org/ikiwiki>.  We already plan to add support for TWiki (including history, since you can just run parsecvs on the TWiki RCS files to get Git), so that we can convert the [Portland State Aerospace Society wiki](http://psas.pdx.edu) (currently in Moin, but with much of its history in TWiki, and with many of its pages still in TWiki format using Jamey's TWiki format for MoinMoin).
>
> Our scripts convert by way of HTML, using portions of the source wiki's code to render as HTML (with some additional code to do things like translate MoinMoin's `\[[TableOfContents]]` to ikiwiki's `\[[toc ]]`), and then using a modified [[cpan HTML::WikiConverter]] to turn this into markdown and ikiwiki.  This produces quite satisfactory results, apart from things that don't have any markdown equivalent and thus remain HTML, such as tables and definition lists.  Conversion of the history occurs by first using another script we wrote to translate MoinMoin history to Git, then using our git-map script to map a transformation over the Git history.

# Access Keys

Would anyone else find this a valuable addition.  In oddmuse and instiki (the only other
wiki engines I am currently using, the edit, home, and submit link tags have an
accesskey attribute.  I find it nice not to have to resort to the mouse for those
actions.  However, it may not be something everyone appreciates.  Any thoughts?

# Editing the style sheet.

It would be nice to be able to edit the stylesheet by means of the cgi.  Or is this possible?  I wasn't able to achieve it.

# Should not create an existing page

This might be a bug, but will discuss it here first.
Clicking on an old "?" or going to a create link but new Markdown content exists, should not go into "create" mode, but should do a regular "edit".

# User database tools?

Any tool to view user database?

Any tool to edit the user database?

# Spaces in WikiLinks?

Hello Joey,

I've just switched from ikiwiki 2.0 to ikiwiki 2.2 and I'm really surprised
that I can't use the spaces in WikiLinks. Could you please tell me why the spaces
aren't allowed in WikiLinks now?

My best regards,

# Various ways to use Subversion with ikiwiki

I'm playing around with various ways that I can use subversion with ikiwiki.

* Is it possible to have ikiwiki point to a subversion repository which is on a different server?  The basic checkin/checkout functionality seems to work but there doesn't seem to be any way to make the post-commit hook work for a non-local server?

> This is difficult to do since ikiwiki's post-commit wrapper expects to
> run on a machine that contains both the svn repository and the .ikiwiki
> state directory. However, with recent versions of ikiwiki, you can get
> away without running the post-commit wrapper on commit, and all you lose
> is the ability to send commit notification emails.

* Is it possible / sensible to have ikiwiki share a subversion repository with other data (either completely unrelated files or another ikiwiki instance)?  This works in part but again the post-commit hook seems problematic.
