| |
| 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 |
| |
| 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. |
