+In the plugin interface, there are hooks for "deleted" and "changed" and the "changed" interfaces includes files which are *either* changed or added.  Is there any way of telling that a file has been added rather than changed?  With some plugins (for example, [[plugins/sidebar]]) if a new page (of a certain sort) is added, the only way one can fix up the dependencies is to rebuild the whole site from scratch.  This is Not Good.  Now, one could do something in the "changed" hook, but since one can't tell if a file has been changed or added, if one did something for every changed file, one would be doing a lot of needless work (so one might as well rebuild the site when one *knows* that a new (relevant) page has been added).
+
+But I really would like to be able to do things just to the *new* files, so is there any way that one can distinguish the changed files from the added files?

+I think that presence dependencies mostly cover this case. But no, there is not currently a hook that gets information about which files changed vs were added. The information is available at the time the hooks are called so some new ones could be added.

+Hi there,
+
+I tried yesterday to make a slide-show for my frontpage. I enabled the [[!iki plugins/meta desc=meta]] and the [[!iki plugins/html desc=html]] plugins, then, on my frontpage, I pointed to the .js files that do the trick and I added the html code to actually run the slide-show. I also set [[!iki plugins/htmlscrubber desc=htmlscrubber]] to skip everything except the Discussion pages. I used this code [[http://www.dynamicdrive.com/dynamicindex14/fadeinslideshow.htm]].
+
+In theory this should have worked but unfortunately it didn't worked at all. I know I can use [[!iki plugins/rawhtml desc=rawhtml]] plugin but with this I get a page that is treated as data, I need the page to be treated as source so I can use directives. I'm now wondering if this is even possible in ikiwiki...
+
+Anyway, I thought to check with you guys. The main idea is to have a simple slide-show with 4 or 5 slides that change every 3 seconds and each slide should link to a different page. Any ideas are extremely welcomed!
+
+Thanks
+
+Marius

+Well, surprise, I tried a different approach and this time it worked perfectly. So, how I did it?...
+
+I created externally a html file with the slid-show I wanted and then put it (along with the javascript files and the images) in the source directory. I rebuilt the wiki and then inlined that html page in the wiki page where I wanted the slide-show. 
+
+So, from now on my wiki will look like any wordpress or drupal eye-candy website but without all that bloat.

+The other (optional) clones are meant for you to work
 on, and commit to, changes should then be pushed to the bare root
 repository.
 
-So, to reiterate, when using Git, you probably want to set up three
-repositories:
-
-* The root repository. This should be a bare repository (meaning that
-  it does not have a working tree checked out), which the other
-  repositories will push to/pull from.  It is a bare repository, since
-  git does not support pushing to a repository that has a working
-  directory. This is called _repository_ in [[ikiwiki-makerepo]]'s
-  manual page. This bare repository has a `post-update` hook
-  that either is or calls ikiwiki's `git_wrapper`, which changes to the
-  working directory for ikiwiki, does a `git pull`, and refreshes ikiwiki
-  to regenerate the wiki with any new content. The [[setup]] page describes
-  how to do this, but note, if you are importing from an existing git repository, that ikiwiki will not create the `git_wrapper` unless its path is explicitely set in your `.setup` file.
-
-* The second repository is a clone of the bare root repository, and
-  has a working tree which is used as ikiwiki's srcdir for compiling
-  the wiki. **Never** push to this repository. It is wise to not make
-  changes or commits directly to this repository, to avoid conflicting
-  with ikiwiki's own changes. When running as a [[cgi]], the changes
-  are committed to this repository, and pushed to the master repository
-  above. This is called _srcdir_ in [[ikiwiki-makerepo]]'s manual page.
-
-* The other (third, fourth, fifth, sixth -- however many pleases you)
-  repositories are also clones of the bare root repository above --
-  and these have a working directory for you to work on. Use either
-  the `git` transport (if available), or `ssh`. These repositories may
-  be on remote machines, your laptop, wherever you find convenient to
-  hack on your wiki. You can commit local changes to the version on
-  the laptop, perhaps while offline. Any new content should be pushed to the
-  bare master repository when you are ready to publish it, and then
-  the post-update hook of the bare repository will ensure that the
-  ikiwiki's source directory is updated, and the ikiwiki refreshed
-  with the new content.

-Using three or more of repositories isn't the most obvious set up, but
+Using three or more repositories isn't the most obvious set up, but
 it works the best for typical ikiwiki use. [[ikiwiki-makerepo]] can
 automate setting this up for the common case where there is no
 pre-existing wiki. [[tips/Laptop_wiki_with_git]] describes a different
 way to set up ikiwiki and git.
 
-It is **paramount** that you **never** push to the non-bare repository
-([this FAQ entry explains why](http://git.or.cz/gitwiki/GitFaq#head-b96f48bc9c925074be9f95c0fce69bcece5f6e73)).
-Instead, clone the bare repository as mentioned above, and push
-**only** to the bare repository.

-The ikiwiki `post-update` hook should be put in the bare repository.

 I have read the hints about using a local wiki to preview changes, but I haven't understood: is it assumed that I should also have a separate "srcdir" for this local preview-wiki (as it is done for the main wiki site), or I could point the local ikiwiki's "srcdir" to the working dir? Can something bad happen if I do this? I guess no, because--as I see it--the reason to have 2 repos for the main site was only enabling pushing to it, so it's a peculiarity of git, and not a requirement for a clean functioning of ikiwiki.

-These are some notes on installing ikiwiki on Mac OS X Snow Leopard. I have a three year old machine with a lot of stuff on it so it took quite a while, YMMV.

-I had terrible trouble installing ikiwiki. It turned out I had accidentally installed Perl through ports. Uninstalling that made everything install nicely.
-I got an error on msgfmt. Turns out this is a program in gettext. I installed that and it fixed the error.

+# MacPorts
+
+The easiest way of installing ikiwiki on Mac OS X [Snow] Leopard and Tiger is via MacPorts: <http://www.macports.org/>
+
+This project ports Open Source software into Mac Os X platform.
+It's very easy to intall ikiwiki via MacPorts:
+
+1.- Donwnload and install MacPorts port manager from:  <http://www.macports.org/install.php> . 
+    Port manager installs via Mac Os X installer. Prerequisite: XCode.
+    Se above URL for details
+
+2.- Run 
+
+    $ sudo port install ikiwiki
+
+This installs ikiwiki and all of its dependencies

+This plugin has now been implemented as [[plugins/contrib/album]].
 
-## Requirements
-
-This plugin formats a collection of images into a photo gallery,
-in the same way as many websites: good examples include the
-PHP application [Gallery](http://gallery.menalto.com/), Flickr,
-and Facebook's Photos "application".
-
-The web UI I'm trying to achieve consists of one
-[HTML page of thumbnails](http://www.pseudorandom.co.uk/2008/2008-03-08-panic-cell-gig/)
-as an entry point to the gallery, where each thumbnail links to
-[a "viewer" HTML page](http://www.pseudorandom.co.uk/2008/2008-03-08-panic-cell-gig/img_0068/)
-with a full size image, next/previous thumbnail links, and
-[[plugins/comments]].
-
-(The Summer of Code [[plugins/contrib/gallery]] plugin does the
-next/previous UI in Javascript using Lightbox, which means that
-individual photos can't be bookmarked in a meaningful way, and
-the best it can do as a fallback for non-Javascript browsers
-is to provide a direct link to the image.)
-
-Other features that would be good to have:
-
-* minimizing the number of separate operations needed to make a gallery -
-  editing one source file per gallery is acceptable, editing one
-  source file per photo is not
-
-* keeping photos outside source code control, for instance in an
-  underlay
-
-* assigning [[tags|ikiwiki/directive/tag]] to photos, providing a
-  superset of Facebook's "show tagged photos of this person" functionality
-
-* constructing galleries entirely via the web by uploading attachments
-
-* inserting grouping (section headings) within a gallery; as in the example
-  linked above, I'd like this to split up the thumbnails but not the
-  next/previous trail
-
-* rendering an `<object>/<embed>` arrangement to display videos, and possibly
-  thumbnailing them in the same way as totem-video-thumbnailer
-  (my camera can record short videos, so some of my web photo galleries
-  contain them)
-
-My plan is to have these directives:
-
-* \[[!gallery]] registers the page it's on as a gallery, and displays all
-  photos that are part of this gallery but not part of a \[[!gallerysection]]
-  (below).
-
-  All images (i.e. `*.png *.jpg *.gif`) that are attachments to the gallery page
-  or its subpages are considered to be part of the gallery.
-
-  Optional arguments:
-
-  * filter="[[ikiwiki/PageSpec]]": only consider images to be part of the
-    gallery if they also match this filter
-
-  * sort="date|filename": order in which to sort the images
-
-* \[[!gallerysection filter="[[ikiwiki/PageSpec]]"]] displays all photos in the
-  gallery that match the filter
-
-So,
-[the gallery I'm using as an example](http://www.pseudorandom.co.uk/2008/2008-03-08-panic-cell-gig/)
-could look something like this:
-
-    \[[!gallery]]
-    <!-- replaced with one uncategorized photo -->
-
-    # Gamarra
-
-    \[[!gallerysection filter="link(sometag)"]]
-    <!-- all the Gamarra photos -->
-
-    # Smokescreen
-
-    \[[!gallerysection filter="link(someothertag)"]]
-    <!-- all the Smokescreen photos -->
-
-    <!-- ... -->
-
-## Implementation ideas
-
-The next/previous part this plugin overlaps with [[todo/wikitrails]].
-
-A \[[!galleryimg]] directive to assign metadata to images might be necessary, so
-the gallery page can contain something like:
-
-    \[[!galleryimg p1010001.jpg title="..." caption="..." tags="foo"]]
-    \[[!galleryimg p1010002.jpg title="..." caption="..." tags="foo bar"]]
-
-However, allowing other pages to push in metadata like that will make
-dependency tracking difficult.
-
-Making the viewer pages could be rather tricky. Here are some options:
-"synthesize source pages for viewers" is the one I'm leaning towards at the
-moment.
-
-### Viewers' source page is the gallery
-
-One possibility is to write out the viewer pages as a side-effect of
-preprocessing the \[[!gallery]] directive. The proof-of-concept implementation
-below does this.  However, this does mean the viewer pages can't have tags or
-metadata of their own and can't be matched by [[pagespecs|ikiwiki/pagespec]] or
-[[wikilinks|ikiwiki/wikilink]].
-
-It might be possible to implement tagging by using \[[!galleryimg]] to assign
-the metadata to the *images* instead of their viewers; however, that would
-require hacking up both `IkiWiki::htmllink` and `IkiWiki::urlto` to redirect
-links to the image (e.g. from the \[[!map]] on a tag page) to become links to
-the viewer page.
-
-Modifications to the comments plugin would also be required, to make it allow
-comments written to `foo/bar/comment_1._comment` even though the page foo/bar
-does not really exist, and display comments on the viewer pages even though
-they're not real pages. (Writing comments to `foo/bar.jpg/*._comment` is not
-an option!)
-
-### Synthesize source pages for viewers
-
-(Edited to add: this is what [[plugins/contrib/album]] implements. --[[smcv]])
-
-Another is to synthesize source pages for the viewers. This means they can have
-tags and metadata, but trying to arrange for them to be scanned etc. correctly
-without needing another refresh run is somewhat terrifying.
-[[plugins/autoindex]] can safely create source pages because it runs in
-the refresh hook, but I don't really like the idea of a refresh hook that scans
-all source pages to see if they contain \[[!gallery]]...
-
-The photo galleries I have at the moment, like the Panic Cell example above,
-are made by using an external script to parse XML gallery descriptions (lists
-of image filenames, with metadata such as titles), and using this to write
-IkiWiki markup into a directory which is then used as an underlay. This is a
-hack, but it works. The use of XML is left over from a previous attempt at
-solving the same problem using Django.
-
-Perhaps a better approach would be to have a setupfile option that names a
-particular underlay directory (meeting the objective of not having large
-photos under source code control) and generates a source page for each file
-in that directory during the refresh hook. The source pages could be in the
-underlay until they are edited (e.g. tagged), at which point they would be
-copied into the source-code-controlled version in the usual way.
-
-> Coming back to this: a specialized web UI to mark attachments as part of
-> the gallery would make this easy too - you'd put the photos in the

-
-The synthetic source pages can be very simple, using the same trick as my
-[[plugins/comments]] plugin (a dedicated [[directive|ikiwiki/directives]]
-encapsulating everything the plugin needs). If the plugin automatically
-gathers information like file size, pixel size, date etc. from the images, then
-only the human-edited information and a filename reference need to be present
-in the source page; with some clever lookup rules based on the filename of
-the source page, not even the photo's filename is necessarily needed.
-
-> Coming back to this later: the clever lookup rules make dependency tracking
-> hard, though. --[[smcv]]
-
-    \[[!meta title="..."]]
-    \[[!meta date="..."]]
-    \[[!meta copyright="..."]]
-    \[[!tag ...]]
-
-    \[[!galleryimageviewer p1010001.jpg]]
-
-However, this would mean that editing tags and other metadata would require
-editing pages individually. Rather than trying to "fix" that, perhaps it would
-be better to have a special CGI interface for bulk tagging/metadata editing.
-This could even be combined with a bulk upload form (a reasonable number of
-file upload controls - maybe 20 - with metadata alongside each).
-
-Uploading multiple images is necessarily awkward due to restrictions placed on
-file upload controls by browsers for security reasons - sites like Facebook
-allow whole directories to be uploaded at the same time, but they achieve this
-by using a signed Java applet with privileged access to the user's filesystem.
-
-I've found that it's often useful to be able to force the creation time of
-photos (my camera's battery isn't very reliable, and it frequently decides that
-the date is 0000-00-00 00:00:00), so treating the \[[!meta date]] of the source
-page and the creation date of the photo as synonymous would be useful.
-
-### Images are the viewer's source - special filename extension
-
-Making the image be the source page (and generate HTML itself) would be
-possible, but I wouldn't want to generate a HTML viewer for every `.jpg` on a
-site, so either the images would have to have a special extension (awkward for
-uploads from Windows users) or the plugin would have to be able to change
-whether HTML was generated in some way (not currently possible).
-
-### Images are the viewer's source - alter `ispage()`
-
-It might be possible to hack up `ispage()` so some, but not all, images are
-considered to "be a page":
-
-* srcdir/not-a-photo.jpg → destdir/not-a-photo.jpg
-* srcdir/gallery/photo.jpg → destdir/gallery/photo/index.html
-
-Perhaps one way to do this would be for the photos to appear in a particular
-underlay directory, which would also fulfil the objective of having photos not
-be version-controlled:
-
-* srcdir/not-a-photo.jpg → destdir/not-a-photo.jpg
-* underlay/gallery/photo.jpg → destdir/gallery/photo/index.html
