Some Ruby scripts I used to import/convert posts from various sources to Jekyll.
# Script to convert a directory of Nanoblogger posts to Jekyll
#
# Nanoblogger is a command line, static blogging app, not that
# dissimilar to Jekyll: http://nanoblogger.sourceforge.net/
#
# It's been years since I've used it though, but the below script
# worked for me in converting the files to Jekyll.
Dir['*.txt'].each do |f|
# Need to read file to find title
title = ''
lines = IO.readlines(f)
lines.each do |l|
if /TITLE/ =~ l
title = l[6..-1].strip # strip leading whitespace, trailing return
break
end
end
lines.slice!(0..lines.index("BODY:\n")) # Remove Nanoblogger front matter
begin
lines.slice!(lines.index("END-----\n")..-1) # Remove Nanoblogger end matter
rescue
lines.slice!(lines.index("END-----")..-1) # Might not have line break
end
# Add in Jekyll Yaml Front Matter
# !Important note to self. I had already split the archive of posts into subfolders based
# on category. So this script would be run on each subfolder and the category manually set
# below.
lines.unshift("---", "layout: page", "type: text", "title: #{title}", "categories: code", "---")
# Replace data in file #IO.writelines?
File.open(f,"w") do |file|
lines.each do |l|
file << l+"\n" # Have to put newlines back in
end
end
# Then rename file based on title
title = title.gsub(/\s/,"-") # replace spaces, any other dodgy characters can manually fix
title = "-"+title # Add leading -
newf = f.gsub(/T.*/, title+".html")
newf = newf.gsub(/\\|\/|:|\*|\?|\"|<|>|\|/, "_") # Windows safe filenames
File.rename(f, newf)
end
# Script to extract posts from a Rails database dump to Jekyll
#
# Hence it's quite specific to the setup I had and probably of
# little use to anyone else.
sql = IO.readlines('newsite_production_dump 11.07.2009.sql')
#temp = sql.select{|v| v =~ /INSERT INTO `posts`/}[0]
#sql.index(temp) # Next line is "VALUES", then data starts until?
# Might as well just manually identify relevant line numbers
# Doesn't deal with Windows fobiles such as question marks not being allowed in file names
sql[61..88].each do |post| # The line numbers in the sql dump that contain the posts.
bit = post.split(/','/)
title = bit[0].match(/'.*/)[0][1..-1] # Starting from single quotation mark, but then removing that
body = bit[1]+bit[2]
body = body.gsub(/\\r\\n/,'').gsub(/\\/,'')
date = bit[3].split(' ')[0] # Lazy, but works
# write somewhere
File.open(date+"-"+title.gsub(/\s/,"-")+".html", "w") do |file|
file << "---\n"
file << "layout: page\n"
file << "type: text\n"
file << "title: #{title}\n"
file << "categories: \n" # Will have to fill these in manually, later
file << "---\n"
file << body
end
end
# Script to download Tumblr posts to Jekyll Format
#
# Note this is somewhat specific to how I intend to use Jekyll, i.e. basically trying to have different
# post "types" in the same way Tumblr does and have special meta data in the Yaml front matter (See
# https://github.com/i5m/i5m.github.com), but the # script could be easily adapted to suit.
