# BlogML import script originally sourced from: | |
# https://github.com/philippkueng/philippkueng.github.com/tree/30ef1570f06d33938b18d5eee7767d6641b9a779/source/_import | |
# Best post I could find about how to use it was here: | |
# http://philippkueng.ch/migrate-from-blogengine-dot-net-to-jekyll.html | |
# | |
# how to install | |
# -------------- | |
# mkdir source/_importer | |
# cp blogml.rb to the source/_importer/ you created above | |
# cp your BlogML.xml to the same source/_importer/ directory | |
# | |
# make sure to change the "categories" output at the end of this script | |
# to be the final resting place of your imported posts. i chose to put mine | |
# all into the /blog/archives/ folder personally. by using categories like | |
# this, it uses the folder structure for all posts to render in that one | |
# directory. | |
# | |
# if you, on the other hand, want to retain your categories as categories | |
# in your new blog, feel free to remove the TAGs portion and copy it to the | |
# CATEGORIES portion in the final output below. It will render the categories | |
# per your BlogML. | |
# | |
# how to run | |
# -------------- | |
# I prefer this method below so you can run the importer multiple times without | |
# effecting any new and existing posts you may have created. because the import | |
# BLOWS OUT YOUR _posts FOLDER! | |
# cd source/_importer/ | |
# ruby -r './blogml.rb' -e 'Jekyll::BlogML.process()' | |
# | |
# that will execute the script only with that folder | |
# | |
# change Log by eduncan911: | |
# | |
# 2014-04-08 | |
# added "alias: " to output, changed old_url to be an array with the original old_url as well as a lowercased version | |
# added "date: " to output | |
# added "tags: " to output to read from categories (since I abused that 10 years ago) | |
# you can change this to "categories: " easily and have the same array for them | |
# added "published: " to output | |
# | |
