Phoghorn is a web-based image gallery with built-in automatic thumbnail generator for spiffy the webserver.
Its features are:
By default, phoghorn assumes there is a directory called galleries in the directory from which you call its functions (ie, the same directory in which you placed index.ssp). It will create thumbnails on-the-fly when there aren't any yet, and only for those pictures on the page that is currently being viewed. By default, these will be placed in the thumbs directory under the gallery's directory.
In the main page (save this as index.ssp):
(use phoghorn spiffy-utils)
(define content
`((html
(head (title "Showing gallery: " ,(get-var (gallery-var))))
(body
(phoghorn-gallery)))))
;; We want bigger pages
(parameterize ((page-size 40))
(output-html content phoghorn-rules pagination-rules shortcut-rules universal-conversion-rules))
In the zoomed-in page (save this as zoomed.ssp):
(use phoghorn spiffy-utils)
(define content
`((html
(head (title "Showing photo: " , (get-var (entry-var)))
(body
(phoghorn-zoomed-entry))))))
;; The shortcut-rules and the pagination-rules are mandatory, by the way
(output-html content phoghorn-rules pagination-rules shortcut-rules universal-conversion-rules)Phoghorn can be customised to the max. The following SRFI parameters are supported, in addition to the configuration options for spiffy-utils pagination (which phoghorn uses internally):
You can use these functions if you want more control over the way your gallery is output, ie using it more as a library than as a complete thumbnail gallery package.
gallery-var).Returns two values: The first value is a list of subgalleries in that gallery, the second value is a list of entries (ie, pictures) in that gallery.thumbnail/epeg or thumbnail/imlib2 based on the entry file. Side-effects: creates the thumbnail if it does not exist and creates the thumb-dirif necessary.thumbnail. Note: the source image must be a jpeg.thumbnail. Note: the source image must be of a type understood by imlib2.entries list, as seen from the selected entry. Returns #f if this is the first entry in the list.entries list, as seen from the selected entry. Returns #f if this is the last entry in the list.This section describes the SXML tags that are available when you use phoghorn-rules.
