KRL (the "Kawa Report Language") is powerful Kawa dialect for embedding
Scheme code in text files such as HTML or XML templates. You select
the KRL language by specifying --krl on the Kawa command line.
KRL is based on on BRL,
Bruce Lewis’s "Beautiful Report Language", and
uses some of BRL’s code, but there are some experimental differences,
and the implementation core is different. You can run KRL in
BRL-compatility-mode by specifying --brl instead of --krl.
This section summarizes the known differences between KRL and BRL. Unless otherwise specified, KRL in BRL-compatibility mode will act as BRL.
"mystring" is the same
as the inverted quote string ]mystring[, and both are instances
of the type <string>.
In KRL "mystring" is a normal Scheme string of type <string>,
but ]mystring[ is special type that suppresses output escaping.
(It is equivalent to (unescaped-data "mystring").)
<. However, KRL in its default
mode does normally escape characters and strings. Thus "<a>"
is written as <a&gr;.
You can stop it from doing this by overriding the output format, for example
by specifying --output-format scheme on the Kawa command line,
or by using the unescaped-data function.
lambda,
take a body, which is a list of one or more declarations and
expressions. In normal Scheme and in BRL the value of a body
is the value of the last expression. In KRL the value of a body
is the concatenation of all the values of the expressions,
as if using values-append.
make-element function specialized
to take the rest of the word as the tag name (first argument).
