Yes, I know that's not a re­al word.

So, the git mas­ter of Niko­la now has plug­ins. In fac­t, not on­ly does it have plu­g­in­s, but is ba­si­cal­ly made of plug­ins.

You see, the code used to most­ly be in­side a class (called Niko­la), and ... it had grown. That class had grown up to around 2000 lines of code. Which is com­plete­ly ridicu­lous.

So, us­ing Yap­sy I turned the code in­side out: al­most all the code that was in that mon­ster class was moved in­to plug­ins and the class turned in­to a smart plug­in load­er.

This has brought sev­er­al ad­van­tages:

• Now you can ex­­tend Niko­la for your own pur­­pos­es. Just cre­ate a plug­in fold­er in your site, and put the ex­­tra func­­tion­al­i­­ty there.

• Sup­­port for whole cat­e­­gories of things is now mod­­u­lar. Want to sup­­port a dif­fer­­ent markup? A dif­fer­­ent tem­­plate sys­tem? Just write a plug­in.

• Want to add com­­plete­­ly new func­­tions to Niko­la? Like, say, a way to im­­port da­­ta from an­oth­er blog tool, or some­thing like plan­et soft­­ware? Well, just add a "com­­mand plug­in".

What has changed for the user?

• You can delete do­do.py from your site.

• Use niko­la build in­stead of doit

• Use niko­la serve in­stead of doit serve

Some mi­nor things still need do­ing in this area (no­table, fix­ing the doc­s), but the main refac­tor­ing is there.

Be­fore I gave up on be­com­ing an ed­u­cat­ed man, I stud­ied math. And to this day it piss­es me that noone has fig­ured out how to make math in­ter­est­ing to the math­-a­verse. Here's a small at­temp­t.

Let's con­sid­er the fol­low­ing sce­nar­i­o, based com­plete­ly on things I know, not things I do ;-)

Sup­pose that in a city called San Isidro, there is a house. Hous­es in San Isidro pay a mu­nic­i­pal tax, in ex­change for the ser­vice of garbage col­lec­tion, street sweep­ing, tree trim­ming, and street light­ing.

It's a very small tax, but let's say it's $100 a month be­cause it's a nice, easy to han­dle num­ber.

Al­so, San Isidro is in a coun­try called Ar­genti­na. In that coun­try there are sev­er­al laws that af­fect the home own­er­s:

1. You can't sell a house if you owe any tax­es.

2. The own­er has a 1% chance of wan­t­ing to sell the house each month.

3. Debts ex­pire af­ter 5 years.

4. If you are sued and you lose, you pay they oth­­er guy's lawyer fees.

5. Lawyer fees are capped to 25% of the mon­ey be­ing dis­­put­ed.

6. Lawyers are re­luc­­tant to help you sue some­one if they get very lit­­tle mon­ey (de­fined as less than $2000)

7. If sued by the city for owed tax­es, the own­er al­ways los­es.

8. Un­­paid tax­es ac­crue 2% com­­pound in­­ter­est mon­th­­ly. So, if you don't pay your $100, you will owe $102, then $104.04, $106.0128 etc.

With all those el­e­ments in place, let's play a game called "Tax Golf"!

The game is played by an in­de­ter­mined num­ber of play­ers called own­ers and one spe­cial play­er called city.

The game is played to 100 "month­s" or un­til all prop­er­ty has been sol­d.

The goal of the game, for the own­er­s, is to pay as lit­tle mon­ey as they can. The score is cal­cu­lat­ed like this: amount of mon­ey you paid di­vid­ed by the time you owned the house.

The own­er with the low­est score is the win­ner.

The goal of the game for the city, is to get as much mon­ey as he can. He's not com­pet­ing against the play­er­s, for him it's a sort of soli­taire where he com­petes against his past per­for­mance.

This, my friends is math. Math is a tool that helps you (a­mong oth­er things) do the right thing in this sort of com­pli­cat­ed, ar­bi­trary, re­al life sce­nari­o.

So, what's a good strat­e­gy for a own­er, and for the city?

In a sec­ond post next wednes­day, I will give some an­swers to those ques­tion­s, us­ing python.

Thanks to the co­op­er­a­tion of Hu­mi­tos who gave me his word­press back­up, I did some im­prove­ments in the word­press.­com im­port fea­ture of Niko­la, my stat­ic web­site/blog gen­er­a­tor

So, if you were to try to use nikola_wordpress_importer from master now, it would:

1. Not crash ;-)

2. Down­load at­­tach­­ments

3. Fix links to at­­tach­­ments so they work on the new site

How­ev­er, I am now un­sure of what ex­act­ly is in word­press.­com's ex­port XML file. The posts them­selves are in this for­m:

Muchas gracias Nico por hacer el video este. Groso, quedó muy bueno.

Two things jump to me:

1. That's not HTML

2. WTF is that youtube thing?

I am hav­ing some suc­cess pro­cess­ing it as mark­down, since that han­dles the para­graph breaks and some oth­er stuff. Maybe the youtube em­bed­ding is done with a mark­down ex­ten­sion?

Any­one knows?

I im­ple­ment­ed a first drat of a word­press.­com im­porter for my Niko­la stat­ic site/blog gen­er­a­tor It's a work in progress but it works well enough that it can turn this blog in­to this blog

What work­s:

• Posts

• Pages

• Drafts

• Tags

• Per­­son­al in­­­for­­ma­­tion

What does­n't work:

• Com­­ments

• Links across post­s/­­pages are left un­­touched

• The out­­put is pret­­ty gen­er­ic

This needs testing, so feel free to get master and try it. Asuming foo.xml is your data from wordpress.com:

nikola_import_wordpress foo.xml
cd new_site
doit && doit serve

And point your brows­er to http://lo­cal­host:8000 to see the re­sult :-)

Minor tweaking of the generated conf.py is generally needed for improved results.
