command to display statistics about repository history
histogram of changes to the repository:
hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
This command will display a histogram representing the number of changed lines or revisions, grouped according to the given template. The default template will group changes by author. The --dateformat option may be used to group the results by date instead.
Statistics are based on the number of changed lines, or alternatively the number of matching revisions if the --changesets option is specified.
Examples:
# display count of changed lines for every committer
hg churn -T "{author|email}"
# display daily activity graph
hg churn -f "%H" -s -c
# display activity of developers by month
hg churn -f "%Y-%m" -s -c
# display count of lines changed in every year
hg churn -f "%Y" -s
# display count of lines changed in a time range
hg churn -d "2020-04 to 2020-09"
It is possible to map alternate email addresses to a main address by providing a file using the following format:
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise a .hgchurn file will be looked for in the working directory root. Aliases will be split from the rightmost "=".
