npm run script < 出乎意料

Question

I recently read an article about generating a changelog and I wanted to integrate it in a package.json script.

I changed the script from the article a bit with the proper project name and to export the output to CHANGELOG.md

 "scripts": {
    "generateChangelog": "git log --pretty=format:'<li> <a href=\"http://git.egt-interactive.com/frontend-games/temporary-test-project/commit/%H\">view commit &bull;</a> %s</li> ' --reverse > CHANGELOG.md"
 },

But when I run it I have the following error:

 < was unexpected at this time. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! temporary-test-project@1.0.0 generateChangelog: `git log --pretty=format:'<li> <a href="http://git.egt-interactive.com/frontend-games/temporary-test-project/commit/%H">view commit &bull;</a> %s</li> ' --reverse > CHANGELOG.md` npm ERR! Exit status 1

I think it's something with the escaping, but I can't find it.

Would be glad for some help. Thanks in advance

EDIT

I am working on windows and by default, I am using Powershell, but I tried to run npm run generateChangelog script with cmd too ( both failed )

However, if I run the same git log... command directly in the shell it works:

git log --pretty=format:'<li> <a href=\"http://git.egt-interactive.com/frontend-games/temporary-test-project/commit/%H\">view commit &bull;</a> %s</li> ' --reverse > CHANGELOG.md`

Yes, you're correct it's an escaping issue.

Change your script named generateChangelog in the scripts section of your package.json to the following:

"scripts": {
  "generateChangelog": "git log --pretty=format:\"<li> <a href=\\\"http://git.egt-interactive.com/frontend-games/temporary-test-project/commit/%H\\\">view commit &bull;</a> %s</li> \" --reverse > CHANGELOG.md"
},

Note the changes:

• The single quotes ( ' ) have been replaced with JSON escaped double quotes ( \\" )

• The JSON escaped double quotes ( \\" ) have been replaced with ( \\\\\\" )

git log --pretty=format:\"<li> <a href=\\\"http://git.egt-interactive.com/frontend-games/temporary-test-project/commit/%H\\\">view commit &bull;</a> %s</li>\" --reverse > CHANGELOG.md
                        ^^             ^^^^                                                                              ^^^^                               ^^

Running $ npm run generateChangelog should now run successfully via:

• Windows Powershell
• Windows Command Prompt (cmd.exe)
• Windows Git Bash
• *Nix command-line tools
