# New-TerminalStackedChangelog generates a markdown file with attribution
|
|
# over a set of revision ranges.
|
|
# Dustin uses it when he's writing the changelog.
|
|
#
|
|
## For example, generating the changelog for both 1.9 and 1.10 might look like this:
|
|
# $ New-TerminalStackedChangelog 1.9..release-1.9, 1.10..release-1.10
|
|
## The output will be a markdown-like document. Each commit will be converted into a
|
|
## single-line entry with attribution and an optional count:
|
|
#
|
|
# * Foo the bar (thanks @PanosP!)
|
|
# * [2] Fix the bug
|
|
#
|
|
# Entries with a count were present in both changelists.
|
|
#
|
|
# If you don't have the release tags/branches checked out locally, you might
|
|
# need to do something like:
|
|
#
|
|
# $ New-TerminalStackedChangelog origin/release-1.8..origin/release-1.9
|
|
|
|
#Requires -Version 7.0
