In order to get started, I followed the Tutorial for writing a parcel.

My environment MacOSX^? 10.4.9

Steps until the first error

• Checked out the latest chandler (0.7 r14561):

   svn co http://svn.osafoundation.org/chandler/trunk/chandler chandler 

• Installed and ran it successfully:
  • make install

  •  ./release/RunChandler --create -W 

• Uninstalled the existing parcel for feeds and created a new directory for a new version

  •  cd projects/Chandler-FeedsPlugin/ 

  •  PYTHONPATH=../../ ../../release/RunPython setup.py develop -u --install-dir=../../ 

  •  cd ../../ 

  •  mkdir ~/Chandler-FeedsPlugin 

  •  cd ~/Chandler-FeedsPlugin 

• Created setup.py file in

   ~/Chandler-FeedsPlugin

  and init.py following the directions

  •  mkdir feeds 

  •  cat > feeds/__init__.py ^D

• Ran the setup in develop mode as instructed

  •  ~/chandler/release/RunPython setup.py develop

• Created and updated

  feeds/channels.py

  by the instructions
• Tried to run Chandler with the new feed parcel

  • ~/chandler/release/RunChandler --create -W

Error: Please unset the CHANDLERHOME environment variable or set it to point to the directory that contains Chandler.py

Solution: unsetting CHANDLERHOME did not help. Setting CHANDLERHOME=~/chandler worked. No further settings were required for this environment variable in later stages.

Confusing:The command --create runs chandler with new repository. It was not clear for me how to run chandler with fresh repository from the instructions.

Further steps

• Tried to run chandler and check the repository.

  • ~/chandler/release/RunChandler --create -W

  • feeds is not listed in the repository, as opposed to the tutorial instructions
• Tried to run chandler after installing the changes for feeds:

  • from ~/Chandler-FeedsPlugin run ~/chandler/debug/RunPython setup.py install

  • ~/chandler/release/RunChandler --create -W

  • feeds is not listed in the repository, as opposed to the tutorial instructions
• Following the tutorial created blocks.py

  •  ~/chandler/release/RunPython setup.py develop

  •  ~/chandler/release/RunPython setup.py install

  •  ~/chandler/release/RunChandler --create -W

  • Chandler crushed on load. Sent error to OSAF.
• Copied the code from the latest version of chandler

  •  code from setup.py, __init.py__, blocks.py and channels.py to files in ~/Chandler-FeedsPlugin

  •  ~/chandler/release/RunPython setup.py develop

  •  ~/chandler/release/RunPython setup.py install

  •  ~/chandler/release/RunChandler --create -W

  • Chandler runs and feeds may be seen in repository.
