thanks this worked for me

Worked for me - thanks!

I had to add require ''rubygems" before feedzirra to make the script work on OS X Lion.

I also had to change the way dates are parsed like this:

created_datetime = post.updated
creation_date = Date.parse(created_datetime.to_s)

I guess the Blogger RSS format must have changed at some point or something.

That's quite probable. I am glad to receive patches.

@bebraw
bebraw commented Apr 23, 2012

Gotcha. I threw in the changes at my fork. Feel free to merge. Might want to test first to make sure I didn't bork things up (I'm a Pythonista :) ).

I just merged your changes. Sorry, that I couldn't figure out a way to keep the credits, but your work is most appreciated! Thank you, sir

@bebraw
bebraw commented Apr 23, 2012

No probs. Thanks. :)

@bebraw
bebraw commented Apr 23, 2012

Hi, one more thing... I noticed it is better to use "created_datetime = post.published" instead of "created_datetime = post.updated". Might want to change that in your gist. You might want to store the updated time in YAML front matter btw. Probably doesn't hurt.

You lost me. YAML?

@bebraw
bebraw commented Apr 24, 2012

See this. It's just that little snippet in front of a page.

I updated my Gist to contain the change mentioned above. Feel free to merge.

Merged. :)

Thanks for this gist. Works

@jorgeramirez

After changing Config to RbConfig it worked. Thanks!

@coolaj86

FYI, if you'd also like to migrate the comments: http://blog.coolaj86.com/articles/migrate-from-blogger-to-ruhoh-with-proper-redirects.html

This requires changing your template (explained in the walkthrough) and exporting a backup of your blog (also explained in the walkthrough)

Thanks for this script! Everything worked well, except the handling of colon characters in the title. They make Jekyll fall over and die, for some reason. Relevant: jekyll/jekyll#549

@nikhil91

thanks:)

Hi Kennym,

Worked for me. Works like a charm. But I had some trouble because the feedzirra module is now renamed to feedjira.
You need to update the script to show that. I did the same and I could do the import then.

I have one question though: I lost the comments I had on blogger in the process. How do I migrate the comments?

raphink commented Aug 13, 2014

+1 for feedjira

@hentleMan

thanks for script!
when I rename feedzirra to feedjira, it work.
but feeds/posts/default option parse only some part of all my posts.
so, I change feeds/posts/default to feeds/posts/default?max-results=100 and it parse all my post.

I link about parsing all post.

@danielgomezrico

I´m getting blogspot_to_jekyll.rb:25:in

': Use RbConfig instead of obsolete and deprecated Config.
blogspot_to_jekyll.rb:27:in <main>': uninitialized constant CONFIG (NameError) after rename it to feedjira, why?

@lolobosse

@danielgomezrico I got the same problem and solved it on my fork @kennym if you want, you can update yours from my code 😄 👍

@mwschwehr

Hi kennym,
Great code. Worked for me on Yosemite with some minor changes.

I removed the deprecated CONFIG call. I think rubygems is now required for El Capitan anyway.

Feedzirra is now called feedjira, so I made the appropriate changes in the code.

After these two minor changes, the code worked perfectly 10.11.3

Feel free to do a pull and merge. In my commit message, i inadvertently stated I was updated for Yosemite. This is my first fork, edit, and push of code on Git, and my first time working in Ruby.
