| 16 | All Python functions must now use four spaces for indentation. | ||
| 17 | Previously, an inconsistent mix of spaces and tabs existed, | ||
| 18 | which made extending these functions using | ||
| 19 | <code class="filename">_append</code> or <code class="filename">_prepend</code> | ||
| 20 | complicated given that Python treats whitespace as | ||
| 21 | syntactically significant. | ||
| 22 | If you are defining or extending any Python functions (e.g. | ||
| 23 | <code class="filename">populate_packages</code>, <code class="filename">do_unpack</code>, | ||
| 24 | <code class="filename">do_patch</code> and so forth) in custom recipes | ||
| 25 | or classes, you need to ensure you are using consistent | ||
| 26 | four-space indentation. | ||
