It could look for example like this on the command line:

emeditor.exe c:\some_dir\some_target_file.txt /mf c:\my_emeditor_macros\delete_every_nth_line.jsee -macroparam “n=3”

Or like this for multiple parameters:

emeditor.exe c:\some_dir\some_target_file.txt /mf c:\my_emeditor_macros\delete_every_nth_line.jsee -macroparam “n=3” -macroparam “start_at_line=2”

Or, to remove the complexity of named parameters, simply using unnamed ordered parameters instead, like this:

emeditor.exe c:\some_dir\some_target_file.txt /mf c:\my_emeditor_macros\delete_every_nth_line.jsee -macroparam 3 -macroparam 2

From inside the macro, the parameter data could for example be accessed from a Javascript object that you provide, e.g. called “MacroParameters”, which could either in the simple case with unnamed ordered parameters only be a simple array of strings, or in the little more complex case with named parameters, e.g. be an “associative array” (using Javascript objects and properties), or alternatively perhaps two simple arrays of strings, where one contains the parameter names and one contains the values.

I really hope that you will consider this enhancement suggestion, since I think it would be a highly useful feature to go with the already super useful possibility to execute macros from the command-line with the “/mf” switch. Thanks for listening!

One big problem with this though is that I haven’t been able to find any way to provide parameters for this macro from this same command line – how can this be done?

A simple example:
I have a macro that will delete every n:th line from the current file, and I want to be able to provide this “n” value (i.e. so that it can delete for example every second line, every third line, every fourth line etc, based on my current choice).

This must be possible somehow, right? But how? I cannot find anything like this in the EmEditor command-line reference?
