  • Windows > Preferences > General > Editors > Text Editors > tick Show line numbers

Debugging with Eclipse

  • Set and remove breakpoints by double clicking in the margin of the code file
  • Click the 'Debug Sahana Eden' button
  • F5 Step into functions
  • F6 Step over lines
  • F7 Step out of functions
  • Use expressions (drag and drop from code) or right-click > watch

Accessing private data

Some data is marked as private to let other developers know they shouldn't access this directly

  • e.g. in s3xrc.py we have S3Resource.__set & S3Resource.__query

This then means that Eclipse can't see these attributes as self.__set, etc.

Instead need to use:

xxx._ClassName__AttributeName

e.g.:

resource._S3Resource__query
resource._S3Resource__set
