Years ago I wrote this for the browser while reading [this article about top-down parsers in python] I got as far as making it into a nifty little calculator at least.

QUESTION
I want to use a web scraping python script in my batch program but I cannot find any examples in the web for this. Hence, it's possible to use python scripts with the ScriptItemProcessor?
Here's my simple code to test this:
...ANSWER
Answered 2021-Mar-29 at 07:21The ScriptItemProcessor delegates item processing to a org.springframework.scripting.ScriptEvaluator. As of v5.3, Spring Framework provides three implementations of the ScriptEvaluator interface: BshScriptEvaluator, GroovyScriptEvaluator and StandardScriptEvaluator.
By default, if you don't specify which ScriptEvaluator to use, the ScriptItemProcessor will use a StandardScriptEvaluator, see Javadoc of setScriptEvaluator. Now this StandardScriptEvaluator is based on JSR-223 javax.script, so you need to make sure the language you want to use is supported by the default ScriptEngine. In your case, python is not a supported language by default, and hence the error.
If you want to use python through JSR-223, you can use Jython (adding the jar of Jython to the classpath should be enough, see Calling Python from Java through scripting engine (jython)?)

QUESTION
(copy from my GitHub issue: https://github.com/spring-projects/spring-boot/issues/22955)
I noticed that Java's ServiceLoader mechanism doesn't work in packaged Spring Boot apps.
BackgroundI've tried to use javax.script.ScriptEngineManager which relies on ServiceLoaders. I was able to successfully launch the app from the IDE but not from the command line.
ANSWER
Answered 2020-Aug-14 at 17:03The ServiceLoader mechanism is correctly finding PyScriptEngineFactory. The problem is then a silent failure when it attempts to create a script engine from it. Unfortunately, when you call getEngineByName(String), ScriptEngineManager swallows any exception thrown by getScriptEngine():

QUESTION
My setup:
- Windows 10
- NVM 1.1.7 for Windows
- node 12.14.1 with npm 6.13.4
- Angular 8.2.14 with @angular/cli 8.3.22
Just trying to run the default angular template:
...ANSWER
Answered 2020-Mar-05 at 10:31It seems the bug is related to this issue and this issue.
Angular indirectly depends on fsevents 1.2.11, which is not supposed to be compiled on Windows (it's a darwin-OS related module). npm ci is bugged and ignores the os field in the module's package.json, so it tries to compile the module anyway, which fails on Windows.
The error did not occur in previous angular versions because fsevents 1.2.9 was directly downloading binaries from AWS instead of compiling them. But due to a loss of access from the devs to the AWS bucket, leading to the impossibility to install the module on node 13, they released the 1.2.11 patch to allow node 13 users to install the package.
Until npm ci gets fixed and/or fsevents gets updated to 2.x in angular, the workarounds on Windows are either:
- Just ignore the error.
npm ciexits wit code 0 because the dependency is optional, so it should not block your deployment script (just slow it down a bit and make it more verbose). The least bad option in my opinion... - Use
npm installinstead ofnpm ci, which will correctly process theosfield offseventsdependencies file. But this will potentially update your dependencies, so it is not really suitable for CI scripts, as it can change versioned files, and does not produce a repeatable output. - Lock the
fseventsmodule version to 1.2.9 instead of 1.2.11 in your dependencies file, so thatnpm cidownloads the binaries instead of compiling them. This won't work when using node 13, as there are no binaries to download for this version of node. Also, I could not find how one should update thepackage.jsonfile to do that (this didn't work for me). - Use
npm ci --no-optional. Unfortunately this doesn't work, because of yet another bug innpm ci.

any advise on how to fix this guys, it is greatly appreciated.. thanks
...ANSWER
Answered 2020-Mar-04 at 17:46This is something related to the latest version of NodeJS which is explained here. I would advise you below two options to get rid of this. Choose the best that suits you.
- Please setup python in your machine
- Downgrade your Nodejs to version 10.X and try it. I am using 10.18.0 and it works perfectly fine. You can download it from here.
