Depuis : 5.1.22The compare filter allows numerical, string and date comparisons to be performed.

The compare operator uses an extended syntax to specify all the options:

[compare:<type>:<mode>[<parameter>]]

The type can be:

• "number" - (default) invalid numbers are interpreted as zero
• "integer" - invalid integers are interpreted as zero
• "string"
• "date" - invalid dates are interpreted as 1st January 1970
• "version" - invalid versions are interpreted as "v0.0.0"

The mode can be:

• "eq" - equal to
• "ne" - not equal to
• "gteq" - greater than or equal to
• "gt" - greater than
• "lteq" - less than or equal to
• "lt" - less than

The operator compares each item in the selection against the value of the parameter, retaining only those items that pass the specified condition.

For example:

[[2]compare:number:eq[3]] returns nothing
[[2]compare:number:lt[3]] returns "2"
[[2]compare::eq[2]] returns "2"

Note that several of the variants of the compare operator are synonyms for existing operators, and are provided in the interests of consistency. For example, compare:string:eq[x] is a synonym for match[x].
