History: Branching
Preview of version: 12
From Tiki 15 onwards, it is possible to include contents of other YAML files in profiles depending on branching logic.
The basic usage is through the use of the !include directive. In YAML, the "!" preceding the string means that that is a directive and some kiind of execution is to happen, returning some kind of output that replaces the directive.
The following is an extremely basic example on how it works:
test.yml
wysiwyg.yml
nonwysiwyg.yml
Each of the options of YAML files to include for a particular key (in the above case, feature_wysiwyg) is an item in a list starting with the !include directive followed by the filename (relative to the profile), and then a condition comparing 2 values using operators.
If the condition is true, then it includes that YAML file and ignores the other conditions. If not it moves on to the next option and performs the test again. It is customary to provide a default YML file in case any of the preceding conditions are not met. This works pretty much is the same way as a typical CASE structure in PHP.
In the above example, wysiwyg.yml will be included and therefore wysiwyg will be on. If on the other hand:
since 1 not equals 2, it will default to the nonwysiwyg.yml and set feature_wysiwyg to 'n'.
Note that the contents of the included YAML files should start with the same key as that to be replaced. For example, wysiwyg.yml and nonwysiwyg.yml both start with "feature_wysiwyg".

Basic usage
The basic usage is through the use of the !include directive. In YAML, the "!" preceding the string means that that is a directive and some kiind of execution is to happen, returning some kind of output that replaces the directive.
The following is an extremely basic example on how it works:
test.yml
preferences: feature_wysiwyg: - !include wysiwyg.yml 1 eq 1 - !include nonwysiwyg.yml
wysiwyg.yml
feature_wysiwyg: y
nonwysiwyg.yml
feature_wysiwyg: n

le: less than or equal to

Using references
Checking value of preferences
To build on the above, it is possible to check the value of the preference and then decide which YAML file to include. For example,preferences: feature_wysiwyg: - !include wysiwyg.yml $preference:feature_page_title$ eq y - !include nonwysiwyg.yml
Checking profile input
This could be especially useful when profiles are executed through Data Channels. The following is an example of a profile that takes an input "juicetype" and creates/updates a wiki page with content depending on whether "juicetype" is "apple" or "orange".juiceapp.yml
objects: - type: wiki_page ref: juicepage data: name: How to Make Your Favorite Juice mode: create_or_update content: - !include apple.yml $profilerequest:juicetype$orange$ eq apple - !include orange.yml
apple.yml
content: wikicontent:applejuice
orange.yml
content: wikicontent:orangejuice
juiceapp/applejuice.wiki
These are the instructions on how to make apple juice. Make sure you have a machine juicer. Cut the apple into approximately 6 wedges.
juiceapp/orangejuice.wiki
These are the instructions on how to make orange juice. First, determine if you are using a machine juicer or a manual juicer. If you are using a manual juicer, cut the oranges into half. If using a machine juicer, peel the oranges.
Current Limitations
- Included YAML files themselves cannot contain !include statements.
- There is no way to do boolean comparisons
