Then +this command applies the arguments passed using the `--trailer` +option, if any, to the commit message part of each input file. The +result is emitted on the standard output. + +Some configuration variables control the way the `--trailer` arguments +are applied to each commit message and the way any existing trailer in +the commit message is changed. They also make it possible to +automatically add some trailers. + +By default, a '<token>=<value>' or '<token>:<value>' argument given +using `--trailer` will be appended after the existing trailers only if +the last trailer has a different (<token>, <value>) pair (or if there +is no existing trailer). The <token> and <value> parts will be trimmed +to remove starting and trailing whitespace, and the resulting trimmed +<token> and <value> will appear in the message like this: + +------------------------------------------------ +token: value +------------------------------------------------ + +This means that the trimmed <token> and <value> will be separated by +`': '` (one colon followed by one space). + +By default the new trailer will appear at the end of all the existing +trailers. If there is no existing trailer, the new trailer will appear +after the commit message part of the ouput, and, if there is no line +with only spaces at the end of the commit message part, one blank line +will be added before the new trailer. + +Existing trailers are extracted from the input message by looking for +a group of one or more lines that contain a colon (by default), where +the group is preceded by one or more empty (or whitespace-only) lines. +The group must either be at the end of the message or be the last +non-whitespace lines before a line that starts with '---'. Such three +minus signs start the patch part of the message. + +When reading trailers, there can be whitespaces before and after the +token, the separator and the value. There can also be whitespaces +indide the token and the value. + +Note that 'trailers' do not follow and are not intended to follow many +rules for RFC 822 headers. For example they do not follow the line +folding rules, the encoding rules and probably many other rules. + +OPTIONS +------- +--trim-empty:: + If the <value> part of any trailer contains only whitespace, + the whole trailer will be removed from the resulting message. + This apply to existing trailers as well as new trailers. + +--trailer <token>[(=|:)<value>]:: + Specify a (<token>, <value>) pair that should be applied as a + trailer to the input messages. See the description of this + command. + +CONFIGURATION VARIABLES +----------------------- + +trailer.separators:: + This option tells which characters are recognized as trailer + separators. By default only ':' is recognized as a trailer + separator, except that '=' is always accepted on the command + line for compatibility with other git commands. ++ +The first character given by this option will be the default character +used when another separator is not specified in the config for this +trailer. ++ +For example, if the value for this option is "%=$", then only lines +using the format '<token><sep><value>' with <sep> containing '%', '=' +or '$' and then spaces will be considered trailers. And '%' will be +the default separator used, so by default trailers will appear like: +'<token>% <value>' (one percent sign and one space will appear between +the token and the value). + +trailer.where:: + This option tells where a new trailer will be added. ++ +This can be `end`, which is the default, `start`, `after` or `before`. ++ +If it is `end`, then each new trailer will appear at the end of the +existing trailers. ++ +If it is `start`, then each new trailer will appear at the start, +instead of the end, of the existing trailers. ++ +If it is `after`, then each new trailer will appear just after the +last trailer with the same <token>. ++ +If it is `before`, then each new trailer will appear just before the +first trailer with the same <token>. + +trailer.ifexists:: + This option makes it possible to choose what action will be + performed when there is already at least one trailer with the + same <token> in the message. ++ +The valid values for this option are: `addIfDifferentNeighbor` (this +is the default), `addIfDifferent`, `add`, `overwrite` or `doNothing`. ++ +With `addIfDifferentNeighbor`, a new trailer will be added only if no +trailer with the same (<token>, <value>) pair is above or below the line +where the new trailer will be added. ++ +With `addIfDifferent`, a new trailer will be added only if no trailer +with the same (<token>, <value>) pair is already in the message. ++ +With `add`, a new trailer will be added, even if some trailers with +the same (<token>, <value>) pair are already in the message. ++ +With `replace`, an existing trailer with the same <token> will be +deleted and the new trailer will be added. The deleted trailer will be +the closest one (with the same <token>) to the place where the new one +will be added. ++ +With `doNothing`, nothing will be done; that is no new trailer will be +added if there is already one with the same <token> in the message. + +trailer.ifmissing:: + This option makes it possible to choose what action will be + performed when there is not yet any trailer with the same + <token> in the message. ++ +The valid values for this option are: `add` (this is the default) and +`doNothing`. ++ +With `add`, a new trailer will be added. ++ +With `doNothing`, nothing will be done. + +trailer.<token>.key:: + This `key` will be used instead of <token> in the trailer. At + the end of this key, a separator can appear and then some + space characters. By default the only valid separator is ':', + but this can be changed using the `trailer.separators` config + variable. ++ +If there is a separator, then the key will be used instead of both the +<token> and the default separator when adding the trailer. + +trailer.<token>.where:: + This option takes the same values as the 'trailer.where' + configuration variable and it overrides what is specified by + that option for trailers with the specified <token>. + +trailer.<token>.ifexist:: + This option takes the same values as the 'trailer.ifexist' + configuration variable and it overrides what is specified by + that option for trailers with the specified <token>. + +trailer.<token>.ifmissing:: + This option takes the same values as the 'trailer.ifmissing' + configuration variable and it overrides what is specified by + that option for trailers with the specified <token>. + +trailer.<token>.command:: + This option can be used to specify a shell command that will + be called to automatically add or modify a trailer with the + specified <token>. ++ +When this option is specified, the behavior is as if a special +'<token>=<value>' argument were added at the beginning of the command +line, where <value> is taken to be the standard output of the +specified command with any leading and trailing whitespace trimmed +off. ++ +If the command contains the `$ARG` string, this string will be +replaced with the <value> part of an existing trailer with the same +<token>, if any, before the command is launched. ++ +If some '<token>=<value>' arguments are also passed on the command +line, when a 'trailer.<token>.command' is configured, the command will +also be executed for each of these arguments. And the <value> part of +these arguments, if any, will be used to replace the `$ARG` string in +the command. + +EXAMPLES +-------- + +* Configure a 'sign' trailer with a 'Signed-off-by' key, and then
