churn

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 "=".

Options:

-r, --rev <REV[+]>
	count rate for the specified revision or revset
-d, --date <DATE>
	count rate for revisions matching date spec
-t, --oldtemplate <TEMPLATE>
	template to group changesets (DEPRECATED)
-T, --template <TEMPLATE>
	template to group changesets (default: {author|email})
-f, --dateformat <FORMAT>
	strftime-compatible format for grouping by date
-c, --changesets
	count rate by number of changesets
-s, --sort	sort by key (default: sort by count)
--diffstat	display added/removed lines separately
--aliases <FILE>
	file with email aliases
-I, --include <PATTERN[+]>
	include names matching the given patterns
-X, --exclude <PATTERN[+]>
	exclude names matching the given patterns
