2.5. Python Chunks

Syntax: [[\ Python chunk ]]

There are many Python users that experience anguish, disgust or dismay upon reading the previous section: "Braces!? Give me real, indented Python!". These intendation zealots will be more comfortable using Python chunks, which is why Spyce supports them. Feel free to use Spyce statements or chunks inter-changeably, as the need arises.

A Python chunk is straight Python code, and the internal indentation is preserved. The entire block is merely outdented (or indented) as a whole, such that the first non-empty line of the block matches the indentation level of the context into which the chunk was placed. Thus, a Python chunk can not affect the indentation level outside its scope, but internal indentation is fully respected, relative to the first line of code, and braces ({, }) are not required, nor expected for anything but Python dictionaries. Since the first line of code is used as an indentation reference, it is recommended that the start delimeter of the tag (i.e. the [[\) be placed on its own line, above the code chunk, as shown in the following example:

    def printHello(num):
      for i in range(num):


Naturally, one should not use braces here for purposes of indentation, only for Python dictionaries. Additional braces will merely generate Python syntax errors in the context of chunks. To recap: a Python statement tag should contain braced Python; A Python chunk tag should contain regular indented Python.
