kandi X-RAY | jsengine Summary
This is a simple wrapper of Javascript engines, it wraps the Javascript interpreter for Python use. There are two ways to call interpreters, via dynamic library loading is internal call which is faster than the other one, via subprocess is external call. JSEngine used to be part of YKDL, which created by @coslyk.

Summary: I am trying to use the documentation on JavaScript SPARQL Functions to get a minimal working example of calling a custom javascript function, but it results in a scriptEngine null error.

...ANSWER
Answered 2022-Mar-10 at 10:28In Apache Jena 3.16.0, the JS engine was Nashorn. Nashorn was deprecated in Java 11 and removed in Java17.
An earlier Java version will have Hashorn in.
Now Jena version 4.4.0 uses the javascript engine of choice which has been added to the classpath, and hence needs to be in the dockerfile. Jena testing uses GraalVM.

Answered 2021-Sep-24 at 05:22I tried Bat To Exe Converter from MajorGeeks.com and it seems to work fine with parameters. One thing I noticed is that when passing arguments to a batch file, %* doesn't include the path of the batch file being run, but the converted exe does.

QUESTION
I want to minify JS and CSS files in maven project. I have used minify-maven-plugin (com.samaxes.maven v1.7.6). As per the documentation (https://samaxes.github.io/minify-maven-plugin/minify-mojo.html), I have set <nosuffix> and <skipMerge> as true because I want to maintain the file structure and replace the minified files with original files. I have also set the <phase>packagephase>. After generating and deploying the WAR file, the JS and CSS files are not minified, they stay the same as before. I also referred to some stackoverflow answers and set the <warSourceExcludes> option as per the suggestion provided at https://stackoverflow.com/questions/22117824/using-samaxes-minify-nosuffix-to-overwrite-original-files After using the <warSourceExcludes> option, when I deploy the WAR file on the server, the JS and CSS files are not available and the application is showing 404 errors for the same. Please refer to my pom.xml configuration:

...ANSWER
Answered 2020-Jul-07 at 14:01You will need to either:
- Find an equivalent Gradle plugin that offers similar capabilities as
minify-maven-plugin - Create your own plugin: Developing Custom Gradle Plugins
From a quick Google search, it seems the org.padler.gradle.minify plugin offers the same capability the Maven one does.
QUESTION
ScriptEngineManager scriptEngineMgr = new ScriptEngineManager();
ScriptEngine jsEngine = scriptEngineMgr.getEngineByName("nashorn");
Mono.fromRunnable(() -> {
System.out.println("11111");
try {
System.out.println("2222");
jsEngine.eval("print(\"hello\");while(1);");
} catch (ScriptException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("3333");
}).timeout(Duration.ofMillis(2000)).doOnError(Exception.class, e -> {
System.out.println("4444");
System.out.println(e.toString());
}).onErrorResume(Exception.class, e -> {
System.out.println("5555");
return Mono.error(e);
}).block();
System.out.println("end!!!");
ANSWER
Answered 2020-Jun-04 at 12:08This is a rather odd use of reactor - if you really want to timeout after 2 seconds, then a more normal / better approach might be to spawn your eval() in a new thread, and interrupt() that thread after a certain time (then dealing with the InterruptedException as appropriate.)
However, to answer the question directly, your onErrorResume() call at the end of the chain is itself returning an Mono.error (essentially a clone of the same erroneous Mono it's dealing with.) When you call block(), this exception is then thrown.
Instead, you probably want to return Mono.empty() rather than Mono.error(e) in that onErrorResume() block.
QUESTION
I am trying to create a standard JS library that is mostly shaped like Qbs (which uses deprecated QScriptEngine) with QJSEngine, so people who make Qt software can add things like file-operations to their plugin JS environment.
You can see the repo here
I've got basic classes exposed to the JS engine, like this:
...ANSWER
Answered 2020-Apr-29 at 18:55The object under construction does not have any association with QJSEngine yet. So you can only do one of the following alternatives:
- Store the engine instance in a static variable if you can ensure that there is only ever one instance of
QJSEnginein your whole application. - Store the engine instance in a thread-local variable (
QThreadStorage) if you can ensure that there is only one engine per thread. - Set the current active engine in the current thread right before evaluating your JS code since. This might be the easiest and yet robust solution.
- Retrieve the engine from a
QJSValueparameter. - Implement a JS wrapper for the constructor
Solution 4.: Passing the engine implicitly via a QJSValue parameter.
I assume that your throwing constructor always has a parameter. QJSValue has a (deprecated) method engine() which you then could use. You can replace any parameter in a Q_INVOKABLE method with QJSValue instead of using QString and friends.
