#
# See the following instructions on how to export your discussions from SourceForge:
# https://sourceforge.net/p/forge/documentation/Project%20Data%20Export/
#
# Change the constants (PROJECT_NAME and JSON_FILE) before running the importer!
#
# Use the following command to run the importer within the Docker container:
# su discourse -c 'ruby /var/www/discourse/script/import_scripts/sourceforge.rb'
class ImportScripts::Sourceforge < ImportScripts::Base
# When the URL of your project is https://sourceforge.net/projects/foo/
# than the value of PROJECT_NAME is 'foo'
PROJECT_NAME = 'project_name'
# This is the path to the discussion.json that you exported from SourceForge.
