For a style to be fully compatible with version 7.0.7, some changes are required.
This knowledge base article describes these changes.
To encourage style authors to adapt the newest features of Textual 7, the template engine version has changed.
To advertise support for the new template engine version, edit the style's styleSettings.plist file.
Modify the Template Engine Versions setting to include version 4.
<key>Template Engine Versions</key> <dict> <key>default</key> <integer>4</integer> </dict>
Added data-appearance attribute to
<body> which is either “dark” or “light”.
The value of this attribute is automatically calculated based on the background color of the style.
Nearly all custom attributes have been renamed to provide greater consistency and easier access
Below is a table of all attributes that have been renamed.
All custom attributes that appeared in <html> have moved to <body>.
The logic that determines which color is assigned to a nickname has changed.
Nicknames are now assigned a consistent, unique color instead of picking from a pool of thirty possibilities.
The new nickname colors are literal RGB or HSL values.
For example: hsl(293, 81%, 69%)
When rendering each template, the color of each nickname is set using a the style attribute.
A custom attribute (formally colornumber) is no longer used to set the color in a rendered template.
It is possible for a custom color to be assigned to a nickname using the setcolor command. To provide a style more context, the attribute data-override-color is added to a nickname when a custom color is set.
The shade of colors assigned will vary depending on whether a style has a light background or
A light background will produce colors that are slightly darker whereas a dark background will produce the opposite.
A style's Underlying Window Color setting is used to infer which shade of colors to assign.
Optionally, a setting named Nickname Color Style can be set. This setting instructs Textual to use a specific shade of colors, regardless of the style's background.
<key>Nickname Color Style</key> <string>HSL-dark</string>
Textual is now capable of showing more than images inline with chat.
Each type of media that is shown inline with chat can be customized by adding rules to its CSS
Selectors follow a common format: they begin with “inline” and a descriptor follows.
.inlineImage .inlineVideo .inlineGfycat .inlineTwitchClips .inlineTwitchLive .inlineVimeo .inlineYouTubeThis list contains example selectors. This list is incomplete.
