Basically it goes like this:
- The action itinerates through all the lines of a given text file / variable / clipboard.
- The current line is written to the “For each” variable;
vtestin your macro. - With the sub-actions you add under “execute the following actions” you can do something on each itineration. Using the
vtestvariable in the sub-actions you can access the content of the current line.
Some use-cases:
- You have a file/variable where each line is the path to an app or file. With the appropriate action you could for example open, read, delete, etc. each app/file.
- You want to extract certain lines from a file/variable.
- You want to count lines.
- …
Given the paucity (ie complete absence as far as I am aware) practical examples of how For Each The Lines in works
Well, there is…
- a Wiki article on this, including an example,
- and even a topic with a full demo “Process Lines in Text File” by @JMichaelTX.
- Here another example.
