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 ( )

class s_expr_writer's trivial constructor.

Member Function Documentation

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.

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.

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.

void s_expr_writer::write_new_line ( void )

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

Don't add a newline if we've just had one.
