How recover composer.json by existing project on symfony2?

I have to work on a project on symphony 2 without composer's config, but with folders vendor/* in the repository.

I want to re-install the composer and generate a configuration for an existing package. Is it possible?

Thanks!

You should create bare composer.json by hand or using command composer init.

And then you can list all the packages under the vendor folder by composer show --installed.

Then just generate require section for your composer.json with listed values. And you are done. You can use regular expressions to do it easier.

composer show --installed \
   | awk '{printf "\"%s\": \"^%s\",\n", $1, $2}' \
   | sed -r 's:\^v:^:g' \
   >> packages.list

I think you can execute composer update, it will show you all packages, and then composer install ... one by one
