In checking "Use V8 as JavaScript engine" condition, some macros recorded in the same condition cannot run successfully

Question

I checked the box Use V8 as JavaScript engine.

The demo.txt could be:

"date": "2019-11-22T20:49:21"
"text": ""

"date": "2019-11-22T20:49:24"
"text": ""

I record the macros that replace \n\n by \n, then I save the macros as Delete redundant newlines.jsee.

document.selection.Replace("\\n\\n","\\n",eeReplaceAll | eeFindReplaceRegExp,0);

But, when I run the .jsee for the same demo.txt, here comes the V8 nesting issues occured warning.

By the way, this problem have not happen in the unchecked case.

What's wrong?

I don't know too much about the JavaScript, so I don't know how to upgrade(or fix) the macros recorded in the case of unchecking Use V8 as JavaScript engine option.

And another quetion, can I set breakpoints for macros files for which help me optimize the macros?

Answer 1

I assume that you are using EMEDITOR PROFESSIONAL. According to the manufacturer page EMEDITOR FREE V21.4 "Record and Run only, no scriptable macros". official website

Destruction to your second question, I use "alert" to stop the script at a certain position or to display a certain value of a variable at a position. Also the line "Redraw = false;" is commented out (//) for debugging. e.g.

if (....){
    ....
    alert("debug loop true")
}else{
    ...
    alert("debug loop else")
}

To the first question, I think I read (can't find the article right now) that the Macro Recorder records in javascript as before (not V8). As you wrote, unchecking "Use V8 as JavaScript engine".

For a simple test, copy the line "alert(" Hello EmEditor")" to the clipboard and then select "Run Clipboard" from the macro menu. If successful, a small window will be displayed. In my environment it is also necessary that the saved script runs first through the following steps:

• Menu Macro

  • Customize...

• My Macros

  • Add (select Macro file)

This is necessary for security reasons.
