I blogged last year about my switch from Markdown to AsciiDoc, and that I was using AsciiDocFX.

I still like AsciiDoc, but AsciiDocFX has been getting on my nerves:

  • It doesn't have a very good update system. It checks for new versions, but it seems like I have to a) uninstall the old version, b) reinstall the new version, otherwise I get problems. I may be doing it wrong, but this made me want to update less.
  • The UI is a little wonky. The live preview sometimes seem to keep its update a few keystrokes behind, meaning that the preview and the document are out of sync. It also tends to get locked up, until I click the Restore button and then Maximize button.

Still, I used it.

But, I built a new computer this week. And I've been setting up my softwares on it. I thought it might be worthwhile to see if there's an AsciiDoc plugin for Visual Studio Code. And, of course there was, because apparently the Code extension ecosystem is booming!

So, I installed AsciiDoc by Joao Pinto, since it came with a live preview. But, it requires me to actually install the asciidoc command line tool.

See?

So, I thought, that should be easy enough. I went to the AsciiDoc site and started following the directions for Windows installation.

Install Ruby

Okay, well now I need to install Ruby. Should be easy enough. I already have Chocolatey NuGet, so I'll just run choco install ruby. No problem. I know that ruby comes with gem, so I should be all set.

Install AsciiDoc

According to AsciiDoc... docs... I just use gem install asciidoc and that should do the trick.

But, no. It's not that easy. Otherwise I wouldn't be writing this blog. I got an error message:

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

I'm sure all you Ruby people or Mac people or whatever already know where this is going, but I had no clue. So I googled it. I found a whole bunch of suggestions on StackOverflow. Some solutions made sense but weren't for Windows, and vice versa. I eventually hit upon some random guy's Gist and SSL upgrades on rubygems.org which lead to me this page on rubygems.org about SSL updates.

Fixing RubyGems Certificate Thingy

So, following that literally:

gem install --local C:\rubygems-update-2.6.7.gem

and then

update_rubygems --no-ri --no-rdoc

and finally

gem uninstall rubygems-update -x

So, I guess that fixed... something? It's described in the gist I linked above. But I don't really understand why it's still a problem for a brand new install of ruby. Not complaining! It worked!

Okay, now Install AsciiDoc

So now gem install asciidoc works. And now I get a live preview of AsciiDoc in Visual Studio Code.

I'll report back after some more time blogging to see if I like this, or if I eventually go back to AsciiDocFx.

Welcome to another "Weekly Concerns". This is a post-a-week series of interesting links, relevant to programming and programmers. You can check out previous Weekly Concerns posts in the archive.

This is a special edition of Weekly Concerns, in that I'm attempting to cover the recent dust up over TDD that was triggered by DHH and responded to by several notable developer pundits. Note that I respect all of the developers in this conversation and I believe they are all making important points, but the way they communicate can be somewhat... abrasive... so make sure your jimmies are secure before you start reading.

Lots of others have weighed in, of course, in blog posts and on Twitter. This type of discussion has been going on since Kent Beck wrote his TDD book; I believe it will continue long into the future. So I guess it's probably a good time to reread Jim Holmes book "Best Practices in Software Engineering and Testing", which is no longer available, but I will reprint in its entirety here (completely from memory, so forgive me if the phrasing isn't quite right):

"Use your brain."

I really enjoyed Cammy's brief talk on AOP in Ruby, and I think she successfully shows that even software written in a dynamically-typed language like Ruby can still benefit from AOP. There is some sort of technical issue early in the video that caused the sound not to be recorded, but it is fixed about 20 seconds in.

Follow Cammy on Twitter.

Maybe this series will turn into an Every-Other-Weekly Concerns?

  • The Ruby Rogues podcast discussed AOP in a recent episode (episode 46). It's a good idea to listen to the whole podcast for context, but they don't really start discussing AOP directly until about 28 minutes in.
  • The proxy/decorator pattern gives some of the same benefits that AOP can give you. Derick Bailey blogged about using proxies and decorators in JavaScript.
  • A couple of white papers for you:
    • FeatureC++ and AOP - What's feature-oriented programming?
    • AOP is Quantification and Obliviousness - "obliviousness" often has a negative connotation, but I believe AOP in a team setting on a properly architected application can free up developers to concentrate on adding business value without having function requirements slowing them down

That's it for this week. Have a great weekend.
