typehandlers.codesink: classes that receive generated source code

Objects that receive generated C/C++ code lines, reindents them, and writes them to a file, memory, or another code sink object.

class pybindgen.typehandlers.codesink.CodeSink

Bases: object

Abstract base class for code sinks

Constructor

>>> sink = MemoryCodeSink()
>>> sink.writeln("foo();")
>>> sink.writeln("if (true) {")
>>> sink.indent()
>>> sink.writeln("bar();")
>>> sink.unindent()
>>> sink.writeln("zbr();")
>>> print sink.flush().rstrip()
foo();
if (true) {
    bar();
zbr();

>>> sink = MemoryCodeSink()
>>> sink.writeln("foo();")
>>> sink.writeln()
>>> sink.writeln("bar();")
>>> print len(sink.flush().split("\n"))
4

indent(level=4)

Add a certain ammount of indentation to all lines written from now on and until unindent() is called

unindent()

Revert indentation level to the value before last indent() call

writeln(line='')

Write one or more lines of code

class pybindgen.typehandlers.codesink.FileCodeSink(file_)

Bases: pybindgen.typehandlers.codesink.CodeSink

A code sink that writes to a file-like object

Parameters:file – a file like object

writeln(line='')

Write one or more lines of code

class pybindgen.typehandlers.codesink.MemoryCodeSink

Bases: pybindgen.typehandlers.codesink.CodeSink

A code sink that keeps the code in memory, and can later flush the code to another code sink

Constructor

flush()

Flushes the code and returns the formatted output as a return value string

flush_to(sink)

Flushes code to another code sink :param sink: another CodeSink instance

writeln(line='')

Write one or more lines of code

class pybindgen.typehandlers.codesink.NullCodeSink

Bases: pybindgen.typehandlers.codesink.CodeSink

A code sink that discards all content. Useful to ‘test’ if code generation would work without actually generating anything.

Constructor

flush()

Flushes the code and returns the formatted output as a return value string

flush_to(sink)

Flushes code to another code sink :param sink: another CodeSink instance

writeln(line='')

Write one or more lines of code
