kedrodiff 0.1.1

kedro-diff
kedro-diff aims to be a familiar interface into comparing two points in
history. Git diffs are fantastic tools but often are too granular to see what
has changed inside the pipeline. kedro-diff aims to be a familiar tool at a
higher level so we can see changes to nodes (names, inputs, outputs, tags).
Installation
pip install kedro-diff

Example
kedro diff --stat develop..master
M __default__ | 6 ++++-
M data_science | 3 +++
M data_engineering | 3 ++-
?? new_pipeline

4 pipelines changed, 5 insertions(+), 4 deletions(-)

Usage
# diff develop into master
kedro diff develop..master

kedro diff develop master

# diff current state with main
kedro diff main

# diff current state with main
kedro diff ..main

# comparing pipelines from two branches
kedro diff master new_branch data_science

Roadmap
1.0.0

commit parser
get pipeline.to_json() for __default__ for two different commits
get pipeline.to_json() for all pipelines for two different commits
--stat compares the number of nodes added or dropped in __default__
--stat compares the number of nodes added or dropped in all pipelines
--stat compares attribute changes (inputs, outputs, tags) in all pipelines
compare input names
compare output names
speed up getting repeat pipelines from the same commit (no need to reaload a new session)
speed up getting repeat commits by checking commit hash (reuse existing json)
minimize untested code

2.0.0
super-size pipeline.to_json()

compare all attributes on a node ( not just inputs, outputs, tags)
allow users to specify custom to_json method
function names
function hashes
catalog _filepath
catalog _sql

Testing
This project strives for 100% test coverage where it makes sense. Other kedro
plugins I have created have suffered development speed by the complexity of
fully testing on a full kedro project. There are so many pieces to get into
place that it becomes difficult to test accross multiple versions of kedro or
keep the tests working as kedro changes. Minimal functionality will be placed
into modules that require a kedro full kedro project in place to work.
