Hi @Kepler-ZZ , can you provide a sample of the JavaScript?

Hi @Kepler-ZZ , can you provide a sample of the JavaScript?

ok, such as this JS，I can't instrument it.

plugin.js.zip

[tntim96]

Yep - it looks like TypeScript.

[Kepler-ZZ]

Yep - it looks like TypeScript.

so TypeScript can't be instrumented?

[tntim96]

Not currently

[Kepler-ZZ]

Not currently

Can the JSCover distinguish JavaScript file and TypeScript file??
for exmaple, if it is TypeScript file,just copy not instrument . If it is JavaScript,will be instrumented. Because my project includes JavaScript and TypeScript. I just want get some of JavaScript coverage. But after I use JSCover's file-mode to instrument ,the directory missed TypeScript file, my project was not complete，So it couldn't be compile and run....

Hi @tntim96 , I also have a try proxy-mode, but it throw an exception :

Exception in thread "main" java.lang.OutOfMemoryError:unable to create new native thread; at java.lang.Thread.start0(Native Method); at java.lang.Thread.start(Thread.java:714); at jscover.server.WebDaemon.start(WebDaemon.java:370); at jscover.Main.runServer(Main.java:491); at jscover.Main.runJSCover(Main.java:447); at jscover.Main.runMain(Main.java:417); at jscover.Main.main(Main.java:406);

It is the same as #166 ,you let us using --threads=50 to solve this problem. but I don't know how to use '--threads=50', I got following exception:

6月 10, 2020 6:20:09 下午 jscover.Main runMain 信息: Args: -ws,--threads=50,--proxy,--port=3128,--report-dir=target/local-storage-proxy,--local-storage JSCover: Unknown option '--threads=50' Usage: java -jar JSCover-all.jar -ws [OPTION]... Run a server for instrumenting JavaScript with code coverage information.

so what should I do? :(

Can the JSCover distinguish JavaScript file and TypeScript file?

No.

--threads=50

That's a file-mode only setting.
