Script doesn't return when calling generate(...)

[stijnherreman]

Consider the following script:

const fs = require("fs-extra");
const glob = require("glob");
const plantuml = require("node-plantuml");

glob("src/**/*.plantuml", (err, matches) => {
  if (err) throw err;

  for (let sourceFilePath of matches) {
    const fileContent = fs.readFileSync(sourceFilePath);
    const uml = plantuml.generate(fileContent);

    const targetFilePath = sourceFilePath
      .replace(new RegExp("^src/"), "dist/")
      .replace(new RegExp(".plantuml$"), ".svg");

    // uml.out.pipe(fs.createWriteStream(targetFilePath));

    console.log(`${sourceFilePath} => ${targetFilePath}`);
  }
});

It will not return (making me stop the script with Ctrl-C) when the const uml = plantuml.generate(fileContent); line is there. It works fine otherwise. Any idea what' wrong?

My bad, fileContent isn't text as expected by generate(...). An error message would be helpful though, I had to debug the script and step through the generate(...) code.

I'll see if I can replicate the behaviour, but if it's hanging on generate as you say. Then it is more likely plantuml itself that is the culprit, making hard to report errors. I could be wrong though. Maybe you saw where it got stuck while you were stepping through the generate code?

I've been unable to reproduce this issue myself, and as mentioned in the previous post it is most likely due to Plantuml getting stuck when processing the file.
