| 1 | """muse code query-history — temporal symbol search across commit history. |
| 2 | |
| 3 | Searches the commit history for symbols matching a predicate expression, |
| 4 | bounded by a commit range. Unlike ``muse code query --all-commits``, this |
| 5 | command is focused on *change events* — it shows when each symbol first |
| 6 | appeared, when it was last seen, how many commits it survived, and how many |
| 7 | distinct implementations it had. |
| 8 | |
| 9 | It answers questions that are impossible in Git: |
| 10 | |
| 11 | * "Find all public Python functions introduced after tag v1.0" |
| 12 | * "Show me every class whose signature changed in the last 50 commits" |
| 13 | * "Which functions were present in tag v1.0 but are gone in tag v2.0?" |
| 14 | * "Find the most volatile symbols in the last 100 commits" |
| 15 | * "What was deleted between the last two releases?" |
| 16 | |
| 17 | Usage:: |
| 18 | |
| 19 | muse code query-history "kind=function" "language=Python" |
| 20 | muse code query-history "name~=validate" --from v1.0 --to HEAD |
| 21 | muse code query-history "kind=class" --from abc12345 |
| 22 | muse code query-history "file~=billing" "kind=function" --json |
| 23 | muse code query-history "kind=function" --changed-only --sort changes |
| 24 | muse code query-history "kind=function" --removed-only --from v1.0 --to v2.0 |
| 25 | muse code query-history "kind=function" --introduced-only --from v1.0 |
| 26 | |
| 27 | Output:: |
| 28 | |
| 29 | Symbol history — kind=function language=Python (42 commits) |
