Syntax

For help understanding a BNF spec, read this.

String ::= TEXT | [' "] RAWTEXT [' "]

Variable ::= @varname ; if the varname is invalid, it will be treated as string

Conditional ::= ( Literal BIN_OP Literal *( BIN_PREC Conditional ) ) ; a basic binary conditional

Operation ::= [unsafe] FN(1#Literal) ; a regular function called with arguments inside parenthesis. Might contain an unsafe before itself.

Cycle ::= 1*Operation

Target ::= Conditional { Cycle *(; Cycle ) }

Voila_script ::= 1*Target

Voila's syntax is composed of a binary conditional statement, followed by the operations, delimited within curly brackets. These are separated into cycles. A cycle is an iteration between all directory files, the operations in every cycle are executed if the file matches the conditional. Operations do execute in parallel, and cycles do execute consecutively. Cycles are separated with ;, and operations' arguments are separated with ,. Variables' prefix is @, and its value changes to the file that is evaluating. Everything within quotes (' or ") will be directly treated as raw and won't evaluate to any variable or other token. For a more intuitive explanation, go to the "Examples" section.

This might seem a little confusing, but just keep reading, and you'll see how everything becomes saner.
