Tasks related to generating output
 
The module Indent supplies a C module that implements some
functions helpful for indenting text produced by PTG functions. The
function names IndentIncr, IndentDecr, IndentNewLine
can be inserted into the user's PTG specification, like
Block: "{" [IndentIncr] $ [IndentDecr] [IndentNewLine] "}"
Stmt: [IndentNewLine] $ ";"
Those PTG specifications should not contain strings with the new line
character, but should have the [IndentNewLine] call instead.
Use the function IndentNewLine to put a linefeed into
the output and indent the next line. IndentIncr increments and
IndentDecr decrements the indentation level.
The width of a single indentation step may be set to n spaces by the
call IndentSetStep (n) executed prior to initiating output
(e.g. by PTGOut).
The module does not have generic parameters.
It is used by writing
$/Output/Indent.fw
in a .specs file.
