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.
