We have become used to the features of svnmailer when used with Subversion, and one of those useful features is that it can limit the maximum length (in lines) of a commit email message. This is terribly useful since once the goes beyond a reasonable number of lines, nobody is going to read the remainder, and if they really want the entire contents of the commits, they can use git itself to get them using the revision IDs present in the message already. Change the post-receive-email script to respond to an 'emailmaxlines' config key which, if specified, will limit the number of lines generated (including headers); any lines beyond the limit are suppressed, and a final line is added indicating the number that were suppressed. --- contrib/hooks/post-receive-email | 33 ++++++++++++++++++++++++++++++++- 1 files changed, 32 insertions(+), 1 deletions(-) diff --git a/contrib/hooks/post-receive-email b/contrib/hooks/post-receive-email index 30ae63d..d3b5fab 100755 --- a/contrib/hooks/post-receive-email +++ b/contrib/hooks/post-receive-email @@ -55,6 +55,11 @@ # "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo" # Be careful if "..." contains things that will be expanded by shell "eval" # or printf. +# hooks.emailmaxlines +# The maximum number of lines that should be included in the generated +# email (including its headers).
