  • Find supported dependency manager manifests

    List all dependencies manifests so you can install them. In a scenario where you want to deploy a number of web applications and run their dependency managers, how could you run all of them in a systematic order. One of the complexity is to ensure you get only your own top level dependencies. That way, you don recursively call development dependencies of your own dependencies. Otherwise you might end up discovering dependency management manifests that are already been pulled by your own projects. # Using this command This command helps me find them and I can then run what?s required to pull them from their respective sources. This command assumes the following: 1. Your code checkouts are in a flat repository layout (i.e. not nested). 2. Finds manifests for: - NPM (nodejs), - Composer (php), - bower, - requirements.txt (Python), and - git submodules Show Sample Output

    find /srv/code -maxdepth 4 -type f -regex ".*\(\(package\|composer|npm\\|bower\)\.json\|Gemfile\|requirements\.txt\\|\.gitmodules\)"

  • Listing all your bundles Entities files to issue a doctrine:generate:entities

    When I do a major change in my entities, I want to find a way to find all my Entities names and create the commande for me. So instead of doing ls src/Your/OwnBundle... and then do it manually, this helps a lot. Show Sample Output

    find ./src -type d -name "Entity" | xargs ls -A | cut -d . -f1 | sed 's_^_app/console doctrine:generate:entities YourOwnBundleName:_'
