# Custom Themes
|
|
CSS in Pepperminty Wiki is managed by 2 principle settings:
|
|
|
|
Setting | Meaning
|
|
----------------|--------------------------------------------------------------
|
|
`css` | The current CSS that should be applied (or the keyword `auto` to signal that the automatic default inbuilt theme should be used instead)
|
|
`css_custom` | Any additional CSS that should be applied.
|
|
|
|
Both of these setting also support a URL instead - in which case a `<link rel="stylesheet" />` will be generated.
|
|
|
|
Pepperminty Wiki _also_ has a theme gallery system, which can be enabled by including the `feature-theme-gallery` module. This is managed by another handful of settings:
|
|
|
|
- `css_theme_autoupdate_url`
|
|
- `css_theme_autoupdate_interval`
|
|
- `css_theme_gallery_index_url`
|
|
|
|
The most important one you'll probably be interested in is `css_theme_gallery_index_url`, which should be a space-separated list of URLs that each point to a theme index file. Said theme index files can contain any number of theme definitions. Once specified, the theme gallery can be accessed through a link in the master wiki settings - or directly via the `theme-gallery` action.
|
|
|
|
Note that the theme gallery obviously needs to make 1 or more external HTTP/S requests in order to function. To this end, a warning message is displayed when you visit the theme gallery to make sure that you're ok with this.
|
|
|
|
|
|
## Hosting your own theme gallery
|
|
Although you are welcome to submit your own theme to Pepperminty Wiki's official repository and default theme gallery via a pull request, hosting your own theme gallery is really quite simple. First, you need a theme index JSON file that looks something like this:
|
|
|
|
```json
|
|
[
|
|
{
|
|
"hash": "f2b4c237020e8663f5a4ff6d29a73eaf2bb431d8c82749244a6752467a16f9ce",
|
|
"id": "none",
|
|
"name": "No theme",
|
|
"description": "A special theme with no CSS. Useful if you want to create your own theme from scratch!",
|
|
"author": "Starbeamrainbowlabs",
|
|
"author_link": "https://starbeamrainbowlabs.com/",
|
|
"minversion": "v0.20"
|
|
},
|
|
{
|
|
"hash": "8841461af4c79d365c5792ba3b93e4fae30bed7574d875e1540539f4ec961c8c",
|
|
"id": "default",
|
|
"name": "Default",
|
|
"description": "The default theme.",
|
|
"author": "Starbeamrainbowlabs",
|
|
"author_link": "https://starbeamrainbowlabs.com/",
|
|
"minversion": "v0.20"
|
|
},
|
|
{
|
|
"hash": "071871fdc91cbcb13ca26bb853dbe32ee36e92a7ae69b9fd51f9a93cc37df8c0",
|
|
"id": "blue",
|
|
"name": "Blue",
|
|
"description": "A more blue theme.",
|
|
"author": "ZestyclosePainting",
|
|
"author_link": "https://reddit.com/u/ZestyclosePainting",
|
|
"minversion": "v0.20"
|
|
}
|
|
]
|
|
```
|
|
|
|
Each theme present in the gallery should be an object in a top-level array. The 7 keys are as follows:
|
|
|
|
Key | Meaning
|
|
--------|--------------------
|
|
`hash` | The SHA256 hash of the theme file itself.
|
|
`id` | The id of the theme. No spaces and only lowercase alphanumeric characters + dashes please.
|
|
`name` | The display name for the theme. Put anything you like here, but it doesn't support HTML.
|
|
`description` | A sentence or 2 describing the theme.
|
|
`author` | The name of the author
|
|
`author_link` | A link to the author's website homepage / social media.
|
|
`minversion` | The minimum version of Pepperminty Wiki required to run the theme.
|
|
|
|
Each theme should be in a subfolder alongside the main theme index file with the name corresponding to the theme's id. The theme CSS should be in a file called `theme.css` inside this folder, and the preview images should have the names `preview_small.png` (displayed by default) and `preview_large.png` (displayed when you click on the small preview). Example:
|
|
|
|
- themeindex.json
|
|
- space/
|
|
- theme.css
|
|
- preview_large.png
|
|
- preview_small.png
|
|
- cheese/
|
|
- theme.css
|
|
- preview_large.png
|
|
- preview_small.png
|
|
- .....
|
|
|
|
It is suggested that the theme CSS file have a heading like this:
|
|
|
|
```css
|
|
/**
|
|
* @id default
|
|
* @name Default
|
|
* @description The default theme.
|
|
* @author Starbeamrainbowlabs
|
|
* @author_link https://starbeamrainbowlabs.com/
|
|
* @minversion v0.20
|
|
*/
|
|
```
