NAME
lazygal - static web gallery generator
SYNOPSIS
lazygal [-h | -v | [options] albumdir]
DESCRIPTION
This manual page explains the lazygal program. This program is a static web gallery generator written in Python.
lazygal works so: you should have an original store of files - possibly containg subdirectories (their names serving as headings if not
using the album metadata feature). This is the source file hierarchy. It will never be modified by lazygal. Then, when launching:
$ lazygal -o /var/www/MyAlbum /home/user/SourceDir
lazygal will analyze the contents of the source hierarchy and will (re)create the target hierarchy, but with all the bells and whistles
defined by the templates. Only missing parts or parts that are not up to date will be generated. There is a limitation to this mechanism
though: although updates in the source directory, in the metadata or in the themes is detected, changes in command line options and
configuration files since last generation are not and the user should manually delete files that need to be generated again.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below. For a complete description, see the -h switch.
-v --version
Show program's version number and exit.
-h --help
Show summary of options.
--quiet
Don't output anything except for errors.
--debug
Output everything that lazygal is doing.
-o DEST_DIR --output-directory=DEST_DIR
Directory where web pages, slides and thumbs will be written (default is current directory).
-t THEME --theme=THEME
Theme name (looked up in theme directory) or theme full path.
--default-style=DEFAULT_STYLE
Default style to apply to the theme.
--template-vars=TPL_VARS
Common variables to load all templates with, e.g. --template-vars='footer=foo bar,color=baz'. For longer variable contents, it is
easier to use a configuration file (see lazygal.conf(5)).
-f --force-gen-pages
Force rebuild of web pages, regardless of the modification times of their dependencies. This is handy when changing a configuration
option affecting these (theme, directory flattening, etc.).
--clean-destination
Clean destination directory of files that should not be there (default is to print a warning but not to delete).
--check-all-dirs
Exhaustively go through all directories regardless of source modification time.
-s IMAGE_SIZE --image-size=IMAGE_SIZE
Size of images, define as name=xxy, ..., eg. small=800x600,medium=1024x768. The special dimensions 0x0 use original size. Refer to the
IMAGE RESIZE DESCRIPTION section for more information on the available syntax.
-T THUMBNAIL_SIZE --thumbnail-size=THUMBNAIL_SIZE
Size of thumbnails, eg. 150x113. Refer to the IMAGE RESIZE DESCRIPTION section for more information on the available syntax.
-q QUALITY --quality=QUALITY
Quality of generated JPEG images (default is 85).
-O --original
Include original photos in output.
--orig-base=RELATIVE_PATH
Do not copy original photos in output directory, instead link them using RELATIVE_PATH as base for those links (discarded without -O).
--orig-symlink
Do not copy original photos in output directory, instead create symlinks to their original locations. This is useful when you plan
transferring the whole directory which lazygal generated to some other location, perhaps with rsync, and you wish to avoid creating an
extra copy of each photo.
Caution
This option is not available on Windows; if you try to use it on that operating system, lazygal will immediately exit with an exit
status of 1.
--puburl=PUB_URL
Publication URL (only useful for feed generation).
-m --generate-metadata
Generate metadata description files where they don't exist in the source tree instead of generating the web gallery. This disables all
other options.
-n THUMBS_PER_PAGE --thumbs-per-page=THUMBS_PER_PAGE
Maximum number of thumbs per index page. This enables index pagination (0 is unlimited).
--pic-sort-by=ORDER
Sort order for images in a subgallery, among 'mtime', 'filename', or 'exif'. (default is 'exif' which is by EXIF date if EXIF data is
available, filename otherwise, sorting EXIF-less images before). Add ':reverse' to reverse the sort order (e.g.
--pic-sort-by=mtime:reverse).
--subgal-sort-by=ORDER
Sort order for subgalleries, among 'exif' (EXIF date of the latest picture in sub-gallery), 'mtime' or 'dirname' (default is
'dirname'). Add ':reverse' to reverse the sort order (e.g. --subgal-sort-by=dirname:reverse).
--dir-flattening-depth=LEVEL
Level below witch the directory tree is flattened. Default is no flattening ('No').
This option makes the program include the web gallery index of child galleries in their parent's gallery index, if their level is
greater than the supplied LEVEL. The level of the album root is 0.
Index pages with multiple galleries (which happens when this section is used) show the pictures links in gallery sections.
The following examples show the produced indexes for a sample album (2 sub-galleries, 1 sub-sub-gallery, 1 picture in each one of
those).
Example 1. --dir-flattening-depth=No (default)
index.html <- sub-gallery links
subgal1/index.html <- index with img1
subgal1/img1.html
subgal1/subsubgal1/index.html <- index with img2
subgal1/subsubgal1/img2.html
subgal2/index.html <- index with img3
subgal2/img3.html
Example 2. --dir-flattening-depth=0
index.html <- contains index for all pics
subgal1/img1.html
subgal1/subsubgal1/img2.html
subgal2/img3.html
Example 3. --dir-flattening-depth=1
index.html <- contains index for all pics
subgal1/index.html <- index with img1 and img2
subgal1/img1.html
subgal1/subsubgal1/img2.html
subgal2/index.html <- index with img3
subgal2/img3.html
-z --make-dir-zip
Make a zip archive of original pictures for each directory.
--webalbum-pic-bg=WEBALBUMPIC_BG
Webalbum picture background color. Default is transparent, and implies the PNG format. Any other value, e.g. red, white, blue, uses
JPEG.
--webalbum-pic-type=WEBALBUMPIC_TYPE
What type of web album thumbnails to generate. By default, lazygal generates the well-loved "messy" thumbnails with randomly selected
pictures from the album each rotated by a random amount and pasted together. This default can also be forced by specifying 'messy' as
WEBALBUMPIC_TYPE.
On the other hand, specifying 'tidy' as the value of this option forces lazygal to skip the rotations, resulting in more regularly
shaped thumbnails which can also be more densely packed. This can be an advantage if not all users of your albums have huge screens :-)
--keep-gps-data
Do not remove GPS data from EXIF tags. By default the location tags are removed for privacy reasons. However, there are situations when
having the location data makes sense and is desired. This is mostly meant to be used with holiday photos.
THEMES
A theme maps to a directory that contains the following items:
theme/browse.thtml
The XHTML template for the theme browse page (displaying one picture).
theme/dirindex.thtml
The XHTML template for the directory index page (pictures and sub-galleries links).
Missing template files will be searched for in the default theme.
This must be valid XML. See http://genshi.edgewall.org/wiki/Documentation/xml-templates.html for syntax. Dependencies for statically
included templates (i.e. with filenames not computed from variables) are automatically computed: when an included template is modified, the
software will automatically figure out which pages to re-generate.
Each file which name starts with SHARED_ is copied to the web album destination under the directory shared and is aimed at being a shared
resource accross your web album (CSS stylesheet, button, etc.).
Each file which extension starts with t is processed through the Genshi text template engine before being copied. See
http://genshi.edgewall.org/wiki/Documentation/text-templates.html for syntax.
Please refer to the examples supplied in /usr/share/lazygal/themes
ALBUM METADATA
If a directory from the source album contains a file named album_description, it is processed as a source of album metadata. The format is
borrowed from another album generating tool - Matew. Each line is treated as one possible tag, unknown lines are simply ignored. Example
content of this file follows:
Example 4. album_description
Album name "My album"
Album description "Description, which can be very long."
Album image identifier relative/path/to/image.jpg
Otherwise, the user can provide metadata in the following files.
SOURCE_DIR/album-name
The title to use for this album directory.
SOURCE_DIR/album-description
The description for this album directory. HTML tags are used verbatim from this file.
SOURCE_DIR/album-picture
The image to use at the top of the album picture stack.
SOURCE_DIR/PICTURE_FILENAME.comment
The description to use for this particular image. Please note that HTML tags are taken as provided in this file for output in the
templates.
FILES
~/.lazygal
User configuration directory.
~/.lazygal/themes
User themes directory.
CONFIGURATION FILES
Multiple configuration files are processed by lazygal. The configuration is initially set up with the defaults. The defaults can be found
in the lazygal source distribution in lazygal/defaults.conf.
Then, the configuration files are processed in the following order, each newly defined value overloading formerly defined values.
Finally, any command-line-provided parameter takes precedence on any configuration file value.
~/.lazygal/config
User configuration file. See lazygal.conf(5) for format.
SOURCE_DIR/.lazygal
Album root configuration file. See lazygal.conf(5) for format.
SOURCE_DIR/gal/.lazygal
Web gallery configuration file. Only the webgal and template-vars sections are red in these files. The configuration applies to the
gallery representing the directory of the configuration file, and all of its sub-directories, unless another configuration file in a
sub-directory overloads some of the defined configuration values. See lazygal.conf(5) for format.
SIZE DESCRIPTION
