Did I forget ...?

A small utility to find files highly coupled to the changes in your branch based on git history. Helps to double-check if you forgot to update something related to the files you worked on.

Installation

$ yarn global add did-i-forget

Usage

$ did-i-forget -c

Example output

❯ did-i-forget -c -n 3
Getting changed paths... Done.
2 files changed against the origin/master
Is cache valid? Yes!
Processed 401 commits.
Generating report... Enjoy!

  ┌────────────────────┬──────────────────────────────────────────┬────────────────┬────────────┐
  │    Changed file    │               Coupled file               │ Shared commits │ Confidence │
  ├────────────────────┼──────────────────────────────────────────┼────────────────┼────────────┤
  │ src/diagnostics.rs │ src/language_features/cquery.rs          │             13 │       0.72 │
  ├────────────────────┼──────────────────────────────────────────┼────────────────┼────────────┤
  │ src/diagnostics.rs │ src/language_features/document_symbol.rs │              7 │        0.7 │
  ├────────────────────┼──────────────────────────────────────────┼────────────────┼────────────┤
  │ src/diagnostics.rs │ src/language_features/signature_help.rs  │              6 │       0.67 │
  └────────────────────┴──────────────────────────────────────────┴────────────────┴────────────┘

In this example did-i-forget tells me that I worked on src/diagnostics.rs and I might want to look into src/language_features/cquery.rs as the former was changed in 72% of commits which addressed src/language_features/cquery.rs in the past.

Options

Threshold

-t 0.5, --threshold 0.5

Set a minimum confidence for a coupled file to be reported.

Top N

-n 1, --ntop 1

How many top coupled files to show for each changed file.

Skip sweeping commits

-s 100, --skip-sweeping 100

Reduce the noise by skipping sweeping changes like re-formatting a bunch of files. By default did-i-forget ignores commits touching 100 or more files.

Cache

Enable git log caching

-c, --cache

Cache is stamped by a master revision head SHA reference and is invalidated when it changes. You really want to use it for repeated runs in large repositories as difference can reach orders of magnitude.

Custom cache path

--cache-file .did-i-forget-cache

Output format

-f table, --format table

Print result as a nicely layed out table or just a raw csv.

Master revision

-m origin/master, --master origin/master

Specify a revision (usually a branch) to diff current state against to find out changed files.

Quiet mode

-q, --quiet

Don't output progress information, only print result. Note that logging goes into stderr and result into stdout so you still can pipe result when logging enabled.
