Taking inspiration from prefix keys and prefix arguments, Transient implements a similar abstraction involving a prefix command, infix arguments and suffix commands. We could call this abstraction a “transient command”, but because it always involves at least two commands (a prefix and a suffix) we prefer to call it just a “transient”.
When the user calls a transient prefix command, a transient
(temporary) keymap is activated, which binds the transient’s infix
and suffix commands, and functions that control the transient state
are added to
post-command-hook. The available
suffix and infix commands and their state are shown in a popup buffer
until the transient is exited by invoking a suffix command.
Calling an infix command causes its value to be changed, possibly by reading a new value in the minibuffer.
Calling a suffix command usually causes the transient to be exited but suffix commands can also be configured to not exit the transient.
The second part of this manual, which describes how to modify existing transients and create new transients from scratch, can be hard to digest if you are just getting started. A useful resource to get over that hurdle is Psionic K’s interactive tutorial, available at https://github.com/positron-solutions/transient-showcase.
This manual is for Transient version 0.3.7.50-git.
