Examples

You can generate test file(s) for the examples that follow:

ssmerge --test-file numbers.csv
ssmerge --test-file numbers_buggy.csv
ssmerge --test-file numbers_buggy_add.csv
ssmerge --test-file numbers_conflict.csv

Example 1

ssmerge numbers_buggy.csv numbers.csv numbers_buggy_add.csv

Merge two CSV tables (numbers.csv and numbers_buggy_add.csv) with a common ancestor (numbers_buggy.csv).

Example 2

ssmerge --theirs numbers_buggy.csv numbers.csv numbers_conflict.csv

Merge numbers.csv and numbers_conflict.csv (with common ancestor numbers_buggy.csv), deferring to numbers_conflict.csv in the case of conflict.

Example 3

ssmerge --ours numbers_buggy.csv numbers.csv numbers_conflict.csv

Merge numbers.csv and numbers_conflict.csv (with common ancestor numbers_buggy.csv), deferring to numbers.csv in the case of conflict.

Example 4

ssmerge --inplace --theirs numbers_buggy.csv numbers.csv numbers_conflict.csv

Merge directly into numbers.csv. Without --inplace, output goes to standard output.
