pip install "lunchable[splitlunch]"

This plugin supports different operations, and some of those operations have prerequisites:

It supports the auto-importing of Splitwise expenses into Lunch Money transactions. This requires a manual asset exist in your Lunch Money account with "Splitwise" in the Name. Expenses that have been deleted or which don't impact you (i.e. are only between other users in your group) are skipped. By default, payments and expenses for which you are recorded as the payer are skipped as well, but these can be overridden by the --allow-payments and --allow-self-paid CLI flags, respectively.

• Accounts:
  • Splitwise must be in the account name

It supports the creation of Splitwise transactions directly from synced Lunch Money accounts. This syncing requires you create a tag called SplitLunchImport. Transactions with this tag will be created in Splitwise with your "financial partner". Once transactions are created in Splitwise they will be split in half in Lunch Money. Half of the split will be marked in the Reimbursement category which must be created.

• Financial Partners:
  • If you only have one friend in Splitwise, this is your Financial Partner
  • Financial Partners can be individual users or groups and transactions will be split accordingly
  • Financial Partners must be specified by their Splitwise Group ID, Splitwise User ID, or Email Address
• Tags:
  • SplitLunchImport
• Categories:
  • Reimbursement

It supports a workflow where you mark transactions as split (identical to Lunch Money -> Splitwise) without importing them into Splitwise. This syncing requires you create a tag called SplitLunch and a category named Reimbursement

• Tags:
  • SplitLunch
• Categories:
  • Reimbursement

It supports the creation of Splitwise transactions directly from synced Lunch Money accounts. This syncing requires you create a tag called SplitLunchDirectImport. Transactions with this tag will be created in Splitwise with the total completely owed by your "financial partner". The entire transaction wil then be categorized as Reimbursement without being split.

• Financial Partners:
  • If you only have one friend in Splitwise, this is your Financial Partner
  • Financial Partners can be individual users or groups and transactions will be split accordingly
  • Financial Partners must be specified by their Splitwise Group ID, Splitwise User ID, or Email Address
• Tags:
  • SplitLunchDirectImport
• Categories:
  • Reimbursement

Note: Some of the above scenarios allow for tagging of a Splitwise tag on updated transactions. This tag must be created for this functionality to work.
