11.Macros ​

65. Record and Execute a Macro ​

Mcross allow us to record a sequence of changes and then paly them back. This tip shows how.

Capture a Sequence of Commands by Recording a Macro ​

  • q{register} start recording
  • qa start recording into register a
  • q stop recording
  • :reg a inspect the contents of register a

Play Back a Sequence of Commands by Executing a Macro ​

  • @{register} executes the contents of the specified register
  • @a executes the contents of register a
  • @@ repeats the macro that was invoked most recently
  • 10@a executes 10 times

66. Normalize, Strike, Abort ​

Executing a macro can sometimes produce unexpected results, but we can achieve better consistency if we follow a handful of best practices.

Normalize the Cursor Position ​

Strike Your Target with a Repeatable Motion ​

Abort When a Motion Fails ​

67. Play Back with a Count ​

68. Repeat a Change on Continuous Lines ​

69. Append Commands to a Macro ​

Sometimes we miss a vital step when we record a macro. There's no need to re-recording the whole thing from scratch. Instead, we can tack extra commands onto the end of an existing macro.

70. Act Upon a Collection of Files ​

71. Evaluate an Iterator to Number Items in a List ​

72. Edit the Contents of a Macro ​
