group — groups a number of logs or groups together.


(group newlabel [existing ...])



A label for the new group.


One or more log command labels for existing logs, or one or more group command labels for existing groups.


On success, t, otherwise one of the following error messages:

(error "textlog: Group newlabel already exists")
(error "textlog: Group or log existing does not exist")
(error "textlog: Too few arguments to group: # < #")
(error "textlog: Invalid command: group")

or, if none of the above errors apply, nil.


The group command lets you group any number of logs or groups. This allows you to give commands that refer to several logs at the same time, because a command specifying the label of a group will be applied to all the logs in that group or its sub-groups.

Groups can be made recursively (ie. groups of groups). Each group must contain either groups or logs, but not both; you are not permitted to have a group consisting of groups and single logs.

This command corresponds to the Cogent C API function LG_Group.
