QTPL fundamentals: layout, punctuation, and names

QTPL grammar

is loosely modelled on the C and C++ languages. Blank lines and spaces may be used freely within template files to improve readability.

Multiple templates in a single file

are not supported.

Comments

are permitted anywhere in a template file. The C++ comment-introducer // is used in QTPL to signify that whatever follows it until the end of the line is a comment.

Keywords (reserved words)

in QTPL are written all-uppercase, e.g. FLOAT.

Declarations and definitions

of plug-in functions and argument attributes are delimited by curly braces {}, which may be nested.

Strings

of printable characters, which may include spaces and the newline-specifier $\backslash$n, are enclosed in ASCII double-quotes e.g. "line 1$\backslash$nline 2". The maximum permitted string-length is 16,000 characters.

Variable names

in QTPL are sequences of letters, digits, underscore and percent characters of arbitrary length; they must begin with a letter, and must be unique within each plug-in template.
