+# Installation/Setup questions
+
+I ran into a problem when installing from svn.  I got "invalid variable
+interpolation" errors for Wrappers.pm.  I added the flag '--extract-all' to
+'po/Makefile' and 'po/t' to the xgettext line.  Once I did that I was able
+to make and make test just fine. --HarleyPig

+
+I have just installed ikiwiki and it works - at least I have the example index.mdwn page
+compiled and visible.  However I have a few issues/problems:-
+
+* A couple of the 'optional' Perl modules aren't optional, you can't install ikiwiki without them,
+these are HTML::Template and HTML::Scrubber (at least I think it was these two, it's a bit messy 
+to go back and find out).
+
+> You're right, HTML::Template is required. HTML::Scrubber is only required
+> in the default configuration, and is optional if the htmlscrubber plugin
+> is disabled. --[[Joey]]
+
+* I don't seem to have got an ikiwiki man page created.
+
+> It should be installed in /usr/share/man, or a similar directory
+> depending on how your perl is set up and how you did the install.
+> --[[Joey]]
+
+> Found it, in /usr/local/share/man, since no other man pages are in either /usr/share/man or in /usr/local/share/man the ikiwiki
+> man page is a bit lonely, and more to the point not on my MANPATH.  Still I have found it now, I'll just move it to somewhere
+> more sensible. [[Chris]]
+
+* Running "ikiwiki --setup ikiwiki.setup" doesn't do anything.  I have edited ikiwiki.setup to
+my local settings.  There are no errors but neither does anything get compiled.  An ikiwiki
+command to explicitly do the compile works fine.  Am I misunderstanding something here?
+
+> Further tests indicate that ikiwiki isn't seeing changed files so doesn't always rebuild.
+> How does ikiwiki decide when to rebuild?  I tried a full command line like "ikiwiki --verbose ikiwiki ~/public_html/ikiwiki --url=http://www.isbd.ltd.uk/~chris/ikiwiki/" and that doesn't do anything
+either though it was the command line I originally used to compile.  After a long interval I 'touch'ed 
+the files and then it *did* compile but 'touch'ing the files after a few minutes only doesn't seem to force a recompile.  I'm even more confused!
+
+> ikiwiki only compiles files whose modification times have changed. It
+> should see any change made as close as a second after the last compile.
+> When run with --setup, ikiwiki always rebuilds every file in the wiki. If
+> --setup is not working, you must have it pointed at the wrong path or
+> something; you can pass -v to see what it's doing. I don't know why it
+> would not see recently changed files; you could try stracing it.
+> --[[Joey]]
+
+> OK, thanks, I don't quite know what was happening before but it seems to be working right now.
+> --[[Chris]]
+
+>> Weird. I wish I knew what happened, but as it's working now, I'm
+>> guessing some kind of user error was involved. --[[Joey]]
+
+* I wish there was a mailing list, much easier for this sort of stuff than this, apart from
+anything else I get to use a decent editor.

+# 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.
+>
+> We will post the scripts as soon as we have them complete enough to convert our wikis.

+# asciidoc or txt2tags ?
+
+Any plugins or support for using asciidoc or txt2tags as the wiki language and/or exporting to asciidoc or txt2tags?
+
+> No, but it should be quite easy to write such a plugin. The otl plugin
+> is a good example of writing a formatting plugin that uses an external
+> conversion program, like asciidoc or txt2tags. --[[Joey]]

-# OpenID

-I just figured I'd edit something on the page with my OpenID, since you've implemented it! --*[Kyle](http://kitenet.net/~kyle/)*=
+Any plugins or support for exporting to LaTeX?
+(If not could use asciidoc or txt2tags mentioned above to generated LaTeX.)

 
 

-> Kyle, If you like openid, I can switch your personal wiki over to use your openid. --[[Joey]]

-# ACL
+>>> Have a look at [pandoc](http://code.google.com/p/pandoc/).  It can make PDFs via pdflatex. --[[roktas]]

 
 

-How about adding ACL? So that you can control which users are allowed
-to read, write certain pages. The moinmoin wiki has that, and it is
-something, that I think is very valuable. 
+----
+
+# Using with CVS?
+
+Any examples of using ikiwiki with cvs?
+
+> No, although the existing svn backend could fairly esily be modified into
+> a CVS backend, by someone who doesn't mind working with CVS. --[[Joey]]

 
 

-> ikiwiki currently has only the most rudimentary access controls: pages
-> can be locked, or unlocked and only the admin can edit locked pages. That
-> could certianly be expanded on, although it's not an area that I have an
-> overwhelming desire to work on myself right now. Patches appreciated and
-> I'll be happy to point you in the right directions.. --[[Joey]]
+----

 
 

->> I'm really curious how you'd suggest implementing ACLs on reading a page.

->>> httpauth plugin for ikiwiki that integrates with that.. [[--Joey]]
+It would be nice to be able to have a button to show "Differences" (or "Show Diff") when
+editing a page. Is that an option that can be enabled?

 
 

->>>> Which would rule out openid, or other fun forms of auth. And routing all access

+
+Any setting for limiting how many kilobytes can be submitted via the "edit" form?
+-- [[JeremyReed]]
+

+
+>> I didn't want it abused accidently or with malice. I was thinking that Perl's CGI.pm would handle this, but I don't see that.

+>> This could be checked using javascript on the client side (before submitting) and by checking size on server side (before saving). --[[JeremyReed]]

-Also, I'd like to request another template parameter which is just
-$config{url}. That way you won't have to hard-code the URL of the wiki into
-the template. -- Ethan
+# Access Keys

 
 

-> That's already available in the BASEURL parameter. --[[Joey]]
+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?

-# Canonical feed location?
+# 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.
+Ok, that's my last 2 cents for a while. --[Mazirian](http://mazirian.com)
+
+> I don't support editing it, but if/when ikiwiki gets file upload support,

+

+
+----
+
+# RecentChanges should show path to wiki sub-pages?
+
+The RecentChanges only shows the final file name for the recently changes file,
+for example "discussion". It would be more useful to see "index/discussion"
+or the path to the sub-page. I think this is handled by the htmllink() routine.
+
+> Went ahead and did this, IMHO the display is ok as-is. --[[Joey]]
+
+----
+
+# 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".
+
+> I belive that currently it does a redirect to the new static web page.
+> At least that's the intent of the code. --[[Joey]]
+
+>> Try at your site: `?page=discussion&from=index&do=create`
+>> It brings up an empty textarea to start a new webpage -- even though it already exists here. --reed
+
+>>> Ah, right. Notice that the resulting form allows saving the page as
+>>> discussion, or users/discussion, but not index/discussion, since this
+>>> page already exists. If all the pages existed, it would do the redirect
+>>> thing. --[[Joey]]
+
+----
+
+# Refreshing RecentChanges page
+
+What do you think about refreshing RecentChanges page (via Meta Refresh Tag)?
+It can be useful for users like me which rather prefer watching the last changes
+in WWW browser tab than subscribing to page. --Pawel

 
 

-Any way to use `inline` but point the feed links to a different feed on the
-same site?  I have news in news/*, a news archive in news.mdwn, and the
-first few news items on index.mdwn, but I don't really want two separate
-feeds, one with all news and one with the latest few articles; I'd rather
-point the RSS feed links of both to the same feed.  (Which one, the one
-with all news or the one with the latest news only, I don't know yet.)
+> Depends, if it were done the time period should be made configurable.
+> Unwanted server load due to refeshing could be a problem for some.

-> Not currently. It could be implemented, or you could just turn off the
-> rss feed for the index page, and manually put in a wikilink to the news
-> page and rss feed. --[[Joey]]
+>> Yes, it should be configurable by ikiwiki admin. I believe he's not
