yarn xliffmerge argument parser broken

[pinetree62]

using your latest version from today:

My Environment:

• ubuntu 19.04
• node 12.4
• angular 8.0.0.1
• yarn 1.16.0 and 1.17.0
• ngx-i18nsupport: 1.1.6

yarn xliffmerge fails to run, it seems to get an extra parameter which it interprets as a language this paramer is the path of xliffmerge (i redacted the paths a little bit)

yarn  xliffmerge -p xliffmerge.json -v en 
 xliffmerge -p xliffmerge.json -v en

ERROR: language "/home/XYZ/src/node_modules/.bin/xliffmerge" is not valid

in your file xliff-merge.js where the command line arguments are parsed

 static parseArgs(argv) {
        const options = {
            languages: []
        };
        for (let i = 1; i < argv.length; i++) {
const arg = argv[i];

its starting from 1,
From what I read here: (found in the internet ;))

// print process.argv
process.argv.forEach(function (val, index, array) {
  console.log(index + ': ' + val);
});
This will generate:

$ node process-2.js one two=three four
0: node
1: /Users/mjr/work/node/process-2.js
2: one
3: two=th

the "real" arguments also should start from 2 not 1.

So if i change line 53 to
for (let i = 2; i < argv.length; i++) {

it works for me.

As an alternative:
addind to the parseArgs something like

else if (arg.length > 0 && arg.charAt(0) === '/') {
                console.log('ignore this');
            }

works too, but i guess thats not generic enough.

Not sure whether this is specific to using yarn or my setup.

I have the same issue running xliffmerge on windows / npm

Sorry for this very late response.
Will have a look at it and fix it in the next version.

I have used patch-package tool with change suggested by @pinetree62 as a workaround.

[MarcusRiemer]

This issue is still present, I can only run xliffmerge from the commandline when discarding the first argument. Otherwise the path to the xliffmerge "binary" entry file is mistaken as a language.

Is there any chance of a hotfix specifically for xliffmerge? I do understand that keeping up with Angulars Builder API is an invidious task, but this neat little tool works quite fine on its own.

As a workaround for Angular 10+, I created a small script to directly call the xliffmerge function

const xliffmerge = require('@ngx-i18nsupport/ngx-i18nsupport/src/xliffmerge/xliff-merge');
xliffmerge.XliffMerge.main([process.argv[0], ...process.argv.slice(2)]);

I call it from package.json

"xi18n:merge": "node xliffmerge.js --profile xliffmerge.json en de"
