KKT Website

2010-02-07T00:00:00-08:00

I need to make KKT website work by Tuesday. I haven’t accomplished anything yet. It’s only a gathering of notes in Tomboy.

Also I’d better create a DB application tomorrow. Though most probably I would not be able to accompish even one of these tasks in such a short period of time.

A little less procrastination, a little more action please.

Heh, test this thing.

Blog without database. Without any frontend. Interesting. And fairly minimalistic. That’s what appealing.

I think that modern programming suffers from overcomplification. I always have this feeling that things should not be so complex. That there are always easier solutions. We do not have to have a factory of generic factory classes to make a static website. We do not even need a database for a simple one.

I’m working on one small website now, unfortunately I absolutely have to use PHP, but I do not use any database, I do not use any framework, I have one model, couple of controllers and couple of views. Of course I do not structure the project around some kind of generic MVC core. I’m not even sure it’s really MVC. Well, we’ll see.

Okay, there are hooks to the rescue

I had a problem with pushing to a repo with a WD. Post-update hook found on a good website promises to help.

Update: The aforementioned hook may be obtained at the following address: http://utsl.gen.nz/git/post-update

1. Cygwin

I use cygwin for all my unix on Windows tasks. You may use MSYS or nothing at all probably, but I will tell you here how to do thing using cygwin. Adjust accordingly.

If you want to install cygwin, go to cygwin.org and get setup.exe. Installation is pretty straightforward. If you don’t have wget check it here. Same applies to git.

2. Prerequisites.

Install wget (leiningen uses it), install git (you will need it in your projects, that’s for sure. And most public clojure projects use it). Also you’ll need Java JDK. Since we are on Windows just download it from http://java.sun.com.

3. Emacs

Go to http://ourcomments.org/cgi-bin/emacsw32-dl-latest.pl and get patched Emacs. If you want to go with bare GNU Emacs download at http://ftp.gnu.org/pub/gnu/emacs/windows/ instead. I am new at this myself so I can’t give you any recommendations on which one to use.

Now go to http://tromey.com/elpa/install.html and do what it says.

M-x package-list-packages

Navigate using keyboard and mark packages for install using i, unmark using u.

clojure-mode
clojure-test-mode
slime
slime-repl
swank-clojure

Now press x and wait until installation is complete. I had some troubles during installation so I had to run package-list-packages again and check packages which failed and install them again.

Now, I had this problem also that slime was not autoloading. I don’t know why, maybe file corruption or the package is bad in ELPA, but I fixed it this way — go to http://github.com/technomancy/slime/blob/master/slime-autoloads.el and copy contents of this file into ~/.emacs.d/elpa/slime-20******/slime-autoloads.el (or just download and replace the file).

Probably you need to restart emacs after fixing this autoloads file.

Now you can run

M-x slime

It will download clojure into ~/.swank-clojure and run REPL. Have fun.

4. Ant, Maven and Leiningen

Download Ant and put all its folders into your cygwin directory, so that its bin contents go to /bin, lib to /lib etc.

Download maven and put its folders into, say, /opt/maven. Then add /opt/maven/bin to your path. You DO NOT want to put mnv to /bin because of maven and cygwin specifics (it will not work, most probably).

Now get leiningen script from my fork http://github.com/jartur/leiningen/blob/master/bin/lein because it supports Cygwin. (Maybe it was pulled into master branch as of now, so you would be better using it then, because I do not promise frequent updates to keep up with the main development of leiningen.) Put it into /bin and run

lein self-install

Now you can create new clojure projects

lein new sample_proj

To put all dependencies in ./lib

lein deps

It will download needed jars and cache them locally in ~/.m2/

To build project

lein clean
lein uberjar

This will create a big jar which contains all dependencies including clojure and clojure-contrib.
