Functions in text keys

We utilize Java's MessageFormat API. The syntax documentation is a little bit hard to read, but it can be found here: MessageFormat

According to the doc, these are all the options:

• {0}
• {0,number}
• {0,number,integer}
• {0,number,currency}
• {0,number,percent}
• {0,number,.......} according to the format defined by DecimalFormat
• {0,date}
• {0,date,short}
• {0,date,medium}
• {0,date,long}
• {0,date,full}
• {0,date,.......} according to the format defined by SimpleDateFormat
• {0,time}
• {0,time,short}
• {0,time,medium}
• {0,time,long}
• {0,time,full}
• {0,time,.......} according to the format defined by SimpleDateFormat
• {0,choice,.......} according to the format defined by ChoiceFormat

Unfortunately, ChoiceFormat is the most complex thing we can support today.

I will make sure we are tracking this limitation for a potential future enhancement.

In the same boat as you, also looking for what "placeholder" functions are actually available for text keys, specifically looking for a way to pass in a boolean into a text key and display two alternative strings, e.g. something like this:

# text key
# custom.text.key.boolean = {0,choice,true#Text when true|false#Text when false}

<#-- we then could do something like that: -->
<#assign text = text.format('custom.text.key.boolean', <boolean_variable>?c) />

this unfortunately doesn't work, but the workaround is as follows

# text key
# custom.text.key.boolean = {0,choice,0#Text when false|1#Text when true}

<#-- then do that that: -->
<#assign text = text.format('custom.text.key.boolean', <boolean_variable>?then(1, 0) />

it works, but maybe the first variant would be more pretty.

SuzieH can you point us to some documentation that explains/lists the functions available for text keys?
