How do I file a new bug?

• In Bugzilla, click on New. Select Dreamwidth Development. In Component, select Style System. Enter a Summary and a Description. Mention style and author(s) in the summary. If you're patching a color theme, add author names and submission URLs to the description. If you're patching a style, mention the style name, the number of themes it has, the name of the default theme, the author's name and the submission URL.

• Click on Show Advanced Fields. Set Initial State to IN_PROGRESS and enter your Bugzilla e-mail address in Assign To.

Where are style files?

• core2.s2 is in ~/dw/bin/upgrading/s2layers/

• Theme and layout .s2 files are in ~/dw/bin/upgrading/s2layers/STYLENAME/ or ~/dw/ext/dw-nonfree/bin/upgrading/s2layers/STYLENAME/

• .pm style files are in ~/dw/cgi-bin/LJ/S2Theme/ or ~/dw/ext/dw-nonfree/bin/upgrading/s2layers/LAYERNAME/

• S2Theme.pm is in ~/dw/cgi-bin/LJ/

• S2Theme_local.pm is in ~/dw/ext/dw-nonfree/cgi-bin/LJ/

FIXME: expecting this to be renamed at some point.

• s2layers.dat is in ~/dw/cvs/dw-free/bin/upgrading/ or ~/dw/ext/dw-nonfree/bin/upgrading/

Checking usage rights

Before you patch any style or theme, make sure Dreamwidth is allowed to use it and the images it contains if there are any:

• If design and images have been made entirely from scratch by the designer who submitted the style or theme they need to sign a Contributor Licensing Agreement before we can use it. They also need to explicitly state they made them themselves in their submission entry.
• If design or images haven't been made entirely from scratch by the designer who submitted the style or theme, they must mention where they came from and how they're licensed. We can only use designs and images if commercial use is allowed, use in website templates is allowed and storage on one own's server is allowed. You must also check if images must be used as-is or any kind of transformation (also called 'remix') is allowed, and how crediting must be done.

There's no need for this kind of verification when the submission is a simple color theme, or uses images from existing themes and styles (see the next section, though).

When in doubt, contact Denise.

Dw-free or dw-nonfree?

Dreamwidth may be allowed to use designs and images on dreamwidth.org but may not be allowed to redistribute or sublicense them to other sites. If that's the case, elements need to go to dw-nonfree:

• Styles go to dw-nonfree if Dreamwidth can use them but can't redistribute/sublicense them.

• Themes go to dw-nonfree if they contain images Dreamwidth can use but can't redistribute/sublicense.

• Themes go to dw-nonfree if the base style is already in dw-nonfree. This the case for Transmogrified and Sunday Morning themes.

Adding a New Style

Edit s2layers.dat

• If this is a new Core2 style, add:

stylename/layout          layout          core2
stylename/themes          theme+          stylename/layout

• If this is a child of Tabula Rasa, add:

stylename/layout          layout(core2base/layout)    core2
stylename/themes          theme+                      stylename/layout

Edit S2Theme.pm

• If the default theme goes to dw-nonfree, edit S2Theme_local.pm instead.

FIXME: expecting this to change at some point.

• Scroll down to %default_themes and add the style and default theme:

layoutname => 'stylename/defaulttheme',

Create STYLENAME.pm

• Create STYLENAME.pm in ~/dw/cgi-bin/LJ/S2Theme/ or ~/dw/ext/dw-nonfree/cgi-bin/LJ/S2Theme/.

• Add:

package LJ::S2Theme::layoutname;
use base qw( LJ::S2Theme );
use strict;
 
sub layouts { ( "1" => "one-column", "1s" => "one-column-split", "2l" => "two-columns-left", "2r" => "two-columns-right", "3" => "three-columns-sides", "3r" => "three-columns-right", "3l" => "three-columns-left" ) }
sub layout_prop { "layout_type" }
 
1;

Remove layout options that don't apply to the style.

• If the style has new Customize properties which can be sorted into existing categories (such as Page, Header, Module, Entry, etc.) you can add them to these categories using sub xxx_props:

sub module_props {
    my $self = shift;
    my @props = qw(
        new_property 1
        new_property 2
        new_property 3
        new_property 4
        new_property 5
    );
    return $self->_append_props( "module_props", @props );
}

Existing categories can be found in ~/dw/cgi-bin/LJ/S2Theme.pm

Note that, in Customize, they will be put after default properties, in the order you've listed them in in layout.s2.

Create the STYLENAME directory

• Create a directory with the name of the style in ~/dw/bin/upgrading/s2layers/ or ~/dw/ext/dw-nonfree/bin/upgrading/s2layers/.

Create layout.s2

• In the directory you've created, create a file named layout.s2. Add:

layerinfo type = "layout";
layerinfo name = "stylename";
layerinfo redist_uniq = "stylename/layout";
layerinfo author_name = "someuser";
layerinfo lang = "en";
 
set layout_authors = [ { "name" => "someuser", "type" => "user" } ];

• Make sure to respect the designer's wishes concerning capitalization and that layerinfo author_name and layout_authors match.

• If the designer doesn't want their name to be displayed as a username, use this instead:

set layout_authors = [ { "name" => "someuser" } ];

• If there are resources to credit, add them:

set layout_resources = [ { "name" => "Name", "url" => "http://URL" } ];

• Add the style code.

• If the style has custom properties, they should be sorted into existing groups (presentation, colors, fonts, images, modules, text, other) by appending _child to the group name. For example:

propgroup images_child
    property string image_module_list { des = "Module list image"; }

• If a module has more or fewer available positions than other modules, you can customize the sections it can be set to by using _override. For example:

    property string module_navlinks_section_override {
        values = "none|(none)|header|Header|one|Group One|two|Group Two";
        grouped = 1;
        }
 
set grouped_property_override = { "module_navlinks_section" => "module_navlinks_section_override" };
 
set module_navlinks_section = "header";

Don't forget to make sure it's printed correctly when set to every position, possibly by editing function Page::print() { }.

Create themes.s2

• In the directory you've created, create a file named themes.s2.

• Follow the steps outlined in the next section.

Adding a New Color Theme

Edit themes.s2

• If the theme goes to dw-nonfree, edit themes-local.s2 instead.

FIXME: expecting this to change at some point.

• Make sure the color theme has the right header. As Afuna explained here in dw_dev_training, it should look like this:

#NEWLAYER: stylename/themename
layerinfo type = "theme";
layerinfo name = "Theme Name";
layerinfo redist_uniq = "stylename/themename";
layerinfo author_name = "someuser";

• If the color theme author is not the style author, add this this line below, separated by a blank line:

set theme_authors = [ { "name" => "someuser", "type" => "user" } ];

• Make sure to respect the designer's wishes concerning capitalization and that layerinfo author_name and theme_authors match.

• If the designer doesn't want their name to be displayed as a username, use this instead:

set theme_authors = [ { "name" => "someuser" } ];

• If there are resources to credit, add them:

set layout_resources = [ { "name" => "Name", "url" => "http://URL" } ];

If there were already resources credited in the style, don't forget to add them again.

• If the theme has any images, name them like this: themename_imagename.xxx. Keep the image name used in other themes if there are any.

If there's only one image, give it the theme name: themename.xxx

If the theme has generic images used in other themes, simply use imagename.xxx.

In the theme, use stylename/themename_imagename.xxx, stylename/themename.xxx or stylename/imagename.xxx as the URL.

• If you need to add theme-specific CSS, use:

function Page::print_theme_stylesheet() {
    """
    CSS HERE
    """;
}

• Make sure to add the theme code in the right place: themes should be alphabetically sorted.

• Each theme file must be separated by two blank lines. Leave one blank line after the last theme in the file.

Check and Format your Files

General Rules

• No tabs or trailing spaces.

• No empty properties.

• No hardcoded colors, fonts or text except shadows, :before/:after characters, colors in print_theme_stylesheet() if the designer has used a non-safe combination (color_page_text on color_entry_background instead of color_entry_text on color_entry_background ) or colors which aren't used elsewhere.

• No redundant code.

• Use shorthand for color codes whenever possible: #555 instead of #555555 and #abc instead of #aabbcc.

• Fonts should be capitalized, and single-quoted if there are several words: 'News Gothic MT' instead of news gothic mt.

Sort S2 Properties

• Sort properties into categories.

In styles, possible categories are: Presentation, Colors, Fonts, Images, Modules, Text, Links List and Custom CSS in this order.

In themes, possible categories are: Presentation, Page Colors, Entry Colors, Module Colors, Fonts and Images, in this order.

Use headers to separate each category:

##===============================
## Page Colors
##===============================

• In themes, properties should be sorted alphabetically within each category, but sometimes logic should prevail. For example, generic properties such as color_page_background go before specific properties such as color_header_background. Look at other themes to keep the same order.

Format CSS

• Format CSS to be easily readable and editable. Everything should be properly indented and spaced out, selectors should be listed in the order they're displayed in the source, properties should be alphabetized.

• In styles, add style name and style author at the top of the stylesheet:

/* Style Name
/* by style author
******************************/
 
* In styles, use comment headers to separate sections:
<syntaxhighlight lang="css">
/* Modules
******************************/
 
.module {
    margin: 2em .5em;
    padding: 2em;
    }

• Remove leading zeros from decimals: .5em instead of 0.5em.

• Use shorthand whenever possible:

    border: 1px solid $*color_module_border;
    border-top: none;
    list-style: square inside url($*image_list_bullet);
    margin: 2em .5em 1em;

instead of:

    border-bottom: 1px solid $*color_module_border;
    border-left: 1px solid $*color_module_border;
    border-right: 1px solid $*color_module_border;
    list-style-image: url($*image_list_bullet);
    list-style-position: inside;
    list-style-type: square;
    margin-bottom: 1em;
    margin-left: .5em;
    margin-right: .5em;
    margin-top: 2em;

• Remove gratuitous specificity such as div.entry instead of .entry. Inserting .DIV and .SPAN when they're not needed makes it harder to override selectors and can cause conflicts or bugs down the line. Compare:

.entry-content {
background: blue;
}
 
div.entry-content {
background: red;
}
 
.entry .entry-content {
background: green;
}
 
div.entry div.entry-content {
background: yellow;
}

• Group selectors whenever possible.

Adding New Files to your Patch

• Type hg addremove if this patch adds or delete files then hg refresh.

• If the style or theme has images, they go to /htdocs/stc/stylename/. If the style folder doesn't exist already, you'll have to create it.

• On Bugzilla, zip them, attach them to your bug and set them to review ? and commit ?.

Test, Test and Test

• For styles, see the list of required features in dreamscapes. Pay attention to color combinations in particular: the style must not only work with the original set of themes but also with dark on light themes, backgrounds where the original designer didn't set one, etc. Anticipate on what users and other designers could do with it.

• In Customize, make sure everything is correctly listed and named. For styles, also make sure you can select the page layouts working with your style, and customize your style.

• On your test account, check colors on all pages. Don't forget hover and visited links, comment subjects, bottom links, reply boxes and drop-down menus on comment pages, contextual pop-ups, the navigation strip, blockquotes in entries and comments if these have been customized. For styles, also make sure all types of layouts, all pages, all sorts of entries and comments are displayed correctly and do so in various screen resolutions and font sizes. Don't forget to check community journals too.

Preview Pictures

• To make preview pictures, you need to take a screenshot of the Recent Pages of your test account. This account needs to have two or three dummy entries with dummy titles and a generic Dreamwidth icon (or the no-userpic default graphic), no navigation strip, and generally few sidebar modules and no footer modules.

• It is best if you take your screenshot when your screen is set to a size of 1366x768 or 1280x800 pixels as these are the most common resolutions used by Dreamwidth users, and your font size set to 14-16 pixels. None of this is mandatory, though.

• Screenshots must then be resized to 150x114 pixels. If doing so distorts the image, you need to either edit the original screenshot in a photo editor program or edit your test journal until your screenshot can be resized without any distortion. You may also need to sharpen your image.

• Final previews should be color-indexed .PNGs, and should NOT include any color profile.

• If you can't do preview pictures mention it on the bug so that someone can do them for you. You can also ask for help at dreamscapes.

• A few tips:

Look at the previews for other themes in the same style; this will generally give you a good idea of the modules you should display, the number of entries you should have and how long they should be to get a good-sized screenshot.

Quick ways to get or lose a few more pixels: add or remove text, line breaks, tags and metadata in entries; change the display of tags in the tags module; change your browser's minimum font size; resize the pic to the correct width then crop it to make it the correct height (one or two 'missing' pixels aren't noticeable at this scale).

It might be a good idea to create accounts specifically for making previews --one per style-- so that you don't lose your set-up.

If your photo editor program has scripting functions, you can use them to automate resizing and saving.

Mozilla Firefox has a few extensions to help you generate content, resize your window and take screenshots:

Dummy Lipsum

Web Developer

FireShot

Google Chrome has two handy extensions (probably more) to help with making screenshots:

Window Resizer will make your browser window a specified size. Especially useful, if you set "screen type" to "mobile device" then the content window is made to the specified size. Using 1280x973 will resize to 150x114 nicely.

Screen Capture will take screen shots of the contents of a browser window (Macs, and maybe other OSs, let you screencap a window but it gives you content and menus, which isn't helpful). A bit buggy but does the job.

If you use a Mac or a Linux machine, you can resize, sharpen, strip any color profiles and make sure the final result is an indexed png from the command line with ImageMagick/convert as long as your screenshot is already the right aspect ratio:

convert -resize '150x114' -sharpen 25 +dither -type Palette $inputfilename png8:$outputfilename

You can also make this into a script:

#!/bin/bash
for f in *.png; do
     convert -resize '150' -sharpen 25 +dither -type Palette "$f" png8:"$f"
done

This version also checks if any of the files have already been done (so doesn't do them again) and prints out the names of the files it resizes:

#!/bin/bash

echo "  Creating Dreamwidth previews..."

for f in *.png; do

    w=$(identify -format "%w" "$f")
    h=$(identify -format "%h" "$f")
    t=$(identify -format "%r" "$f")
    c=$(identify -format "%k" "$f")

    if [ $w -ne 150 ] || [ $h -ne 114 ] || [ $t != "PseudoClassRGB" ] || [ $c -gt 256 ]; then 
        echo "    * $f"
        convert -resize '150' -sharpen 25 +dither -type Palette "$f" png8:"$f"
    fi

done

echo "  ... done"
