GitBook CodeGroup Plugin

Add Plugin

book.json

{
    "plugins": ["codegroup"]
}

then run

$ gitbook install

Configure (Optional Step)

book.json

"pluginsConfig": {
    "codegroup":{
        "defaultTabName": "Code",
        "tabNameSeperator": "::",
        "rememberTabs": true
    }
}

Config Options:

Option	Description
defaultTabName {string} default: Code	a fallback tab name if no language is specied for a fenced code block
tabNameSeperator {string} default: ::	a string delimeter that differentiates the language name from the tab name
rememberTabs {boolean} default: false	determines if the plugin will remember the selected tab, given the info in the codegroup has not changed

Template

{% codegroup %}
```js::sdk
    var s = console.log;
```
```js
    var s = console.warn;
```
{% endcodegroup %}

Args

codegroup takes optional named arguments:

• rememberTabs (boolean): Overrides value in pluginsConfig.codegroup.rememberTabs.
• defaultTabName (string): A default tab name to use for the specific code group. Overrides value in pluginsConfig.codegroup.defaultTabName

example:

{% codegroup rememberTabs=true, defaultTabName="Snippet" %}
```js::nodejs
    var s = "sample";
```
```swift
    let s: String = "sample";
```
{% endcodegroup %}

Notes:

• ebook/PDF compatible
• The goal of this project is to write codegroups/codetabs as close to markdown as possible

Custom Named Tabs

As seen in the example above, tabs can have custom names for situations where it is required to group the same language and there is need to differentiate them.

The example above shows a code block js::sdk, where js is the language syntax to be used and sdk denotes the name to be seen in the tab; :: (configurable) is used to separate both terms.

Custom Print Titles

It is also possible to supply a Print Title using a second tabNameSeperator

Examples:

Example	Description
Explicit js::sdk::Javascript SDK	When converted to pdf, Javascript SDK will be placed above the code block
Syntax+Print Only js::::Javascript SDK	It is possible to omit the custom tab name by using a double tabNameSeperator
TabName+Print Only ::sdk::Javascript SDK	It is possible to omit the syntax name to only define the custom tab name and print title
Print Only ::::Javascript SDK	It is possible to omit the syntax name and custom tab name by using a double tabNameSeperator

CodeGroup Use Case:

• This is ideal for displaying similar usages of the same code in multiple languages
  • for example an sdk that can be used in several languages
