This is the source for the Kotlin Web Site
We use YouTrack for bug reports and suggestions. Click here to report an issue.
Site is based on Jekyll, so you will need ruby (>= 1.9.3) and rubygems to get it working.
- Mac OS X. Make sure that you have Command Line Developer Tools.
- Windows. Step-by-step Jekyll installation can be found here. We recommend to use Cygwin or Git Bash as command line interface.
Run ./INSTALL.sh to install.
To build PDF you will also need wkhtmltopdf:
- Mac OS. 0.12.1 testing build 10.6+ (Carbon).
- Windows. 0.12.1 testing build Windows (MSVC 2013).
- Linux. Stable 0.12.0.
Site uses rake for build management.
To list available commands, run rake from project folder with no arguments.
rake buildgenerates site in the_sitefolder. Usedestparameter to specify another location:rake build dest=/path.rake previewruns built-in development server that will allow you to preview what the generated site will look like in your browser locally. Changed files are rebuilt automatically. Host address and port can be changed by passing the following parameters:rake preview host=172.20.209.23 port=3000rake build_pdfbuilds a PDF from documentation pages and stores it in the default folder. To change location, specifyfile:rake build_pdf file=book.pdf.
All data is stored in the *.yml files in folder _data:
- _nav.yml site navigation and PDF building.
- releases.yml info about releases.
- videos.yml data for the Videos page. The
contentproperty is used to create categories. It contains a list of videos or other categories. Maximum tree depth level is 3. - events.yml event data.
Jekyll uses Liquid template engine. You can use variables, loops, conditions and filters to define content of pages. More information can be found here and here.
The list of global variables accessible from each page can be found here.
To access the folder data from _data, use the following syntax: {{ site.data.%filename%.%key% }}. E.g.:
{{ site.data._nav.main.try.url }}- gets address for Try Kotlin page.{{ site.data.releases.latest.version }}- gets the latest Kotlin version.
Every page can have an unlimited number of metadata fields. More information here.
The most important of them are the page template (e.g. layout: reference) and its type (e.g. type: tutorial). category and title fields are added for future development.
Kramdown with some additions (like GitHub fenced code blocks) is used as markdown parser. See the complete syntax reference at Kramdown site.
In progress, see this reference instead.
With Kramdown you can assign HTML attributes to page elements via {:%param%}. E.g.:
*important text*{:.important}- produces<em class="important">important text</em>*important text*{:#id}- produces<em id="id">important text</em>
For block elements this instruction must be specified on the line following element definition:
This is a paragraph
{:.important}
This is a paragraph
More information about attributes can be found here.
{:.keyword}highlights a keyword.{:.error}highlights an error.{:.warning}highlights a warning.
{:.wide}stretches a table to occupy the entire width of a page.{:.zebra}interleaves table rows.
E.g.:
| Expression | Translated to |
|------------|---------------|
| `a++` | `a.inc()` + see below |
| `a--` | `a.dec()` + see below |
{:.wide.zebra}
They're used in a slightly other manner that they were originally designed for: as universal block container elements.
{:.note}highlights a note block.
E.g.:
> **`inc()/dec()` shouldn't mutate the receiver object**.
>
> By "changing the receiver" we mean `the receiver-variable`, not the receiver object.
