Pulse highlight on demand or after select functions
This is a small package that temporarily highlights the current line after a given function is invoked. The affected functions are defined in the user option `pulsar-pulse-functions' and the effect takes place when either `pulsar-mode' (buffer-local) or `pulsar-global-mode' is enabled. The overall duration of the highlight is determined by a combination of `pulsar-delay' and `pulsar-iterations'. The latter determines the number of blinks in a pulse, while the former sets their delay in seconds before they fade out. The applicable face is specified in `pulsar-face'. To disable the pulse but keep the temporary highlight, set the user option `pulsar-pulse' to nil. The current line will remain highlighted until another command is invoked. To highlight the current line on demand, use the `pulsar-pulse-line' command. When `pulsar-pulse' is non-nil (the default), its highlight will pulse before fading away. Whereas the `pulsar-highlight-line' command never pulses the line: the highlight stays in place as if `pulsar-pulse' is nil. To help users differentiate between the pulse and highlight effects, the user option `pulsar-highlight-face' controls the presentation of the `pulsar-highlight-line' command. By default, this variable is the same as `pulsar-face'. Pulsar depends on the built-in `pulse.el' library. Why the name "pulsar"? It sounds like "pulse" and is a recognisable word. Though if you need a backronym, consider "Pulsar Unquestionably Luminates, Strictly Absent the Radiation".
