Detailed Description

A class for writing out s-expressions, keeping track of newlines and
nested indentation.   

Constructor & Destructor Documentation

s_expr_writer()

s_expr_writer::s_expr_writer

(

)

class s_expr_writer's trivial constructor.   

Member Function Documentation

begin_s_expr()

void s_expr_writer::begin_s_expr

(

const char *

tag

)

Write the beginning of a new s-expresion e.g. "(!foo "
The writer automatically adds whitespace to show the hierarchical
structure of the expressions, so each one starts on a new line,
and any within it will be at an increased indentation level.

end_s_expr()

void s_expr_writer::end_s_expr

(

void

)

Write out the end of an s-expression: any necssessary indentation,
a closing parenthesis, and a new line.

write_any_indent()

void s_expr_writer::write_any_indent

(

int

leading_spaces

)

If we've just had a newline, write the indentation amount, potentially
omitting some spaces.

LEADING_SPACES exists to support code that writes strings with leading
spaces (e.g " foo") which might occur within a line, or could be the first
thing on a line.  By passing leading_spaces == 1, when such a string is the
first thing on a line, write_any_indent () swallows the successive
leading spaces into the indentation so that the "foo" begins at the expected
column.

write_new_line()

void s_expr_writer::write_new_line

(

void

)

Write a newline to the output file, merging adjacent newlines.
