How to inject to open devtools in Electron

[CHENKAI00]

I successfully injected your config. But But I can't see any effect. Where are the parameters of “console.log ” logged? In addition, This project seems to only support injecting native v8 functions, which I am not sure. I have a question. If I want to open devtools, What code should I inject instead? I tried this script:
var allWebContents = require('electron').webContents.getAllWebContents() allWebContents.forEach((contents)=>{ if (contents.openDevTools) { contents.openDevTools(); } } But failed.
I don't know if my way is wrong. I sincerely look forward to your reply. Thank you very much.

It will log to stdout default. Could you provide log?

This is the log. In your config file, You replaced “originalConsoleLog” with “console.log” and added 'now you see:' log. But I can not see it. The hook script seems to have no effect.

Sorry, I seem to know where I am wrong

[CHENKAI00]

But I still do not konw what script I can inject to open devtools.

In addition, I found some electron applications were started with "jsc" files, and the injection failed again.
I'm very sorry to keep submitting issues to you. I'm sorry if I have disturbed you.
