It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my `.zshrc` and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian ([original](//archlinux.org.ru/forum/topic/12752/ "Forum thread")).

This package uses [qbs](//qt-project.org/wiki/qbs "Wiki") for building, which is a bit strange IMHO. A package, which is necessary for building, is [in AUR](//aur.archlinux.org/packages/qbs-git/ "AUR") . I recommend to use git version of the package. When I asked Andrea Scarpino (who maintains KDE and Qt packages into the official repos) about qbs, he told me "we will support it in time". And I agree with him, the project seems to be a little unstable.

* **Shell** is zshrc and nothing else. You may find a small description of my settings [here](/en/2014/01/14/about-zshrc/ "About zshrc paper"). It is stored [here](//raw.githubusercontent.com/arcan1s/dotfiles/master/zshrc "File") (or [here](//raw.githubusercontent.com/arcan1s/dotfiles/master/zshrc_server "File")).
* **DE** - I use KDE as Desktop Environment. And that's why most of apps are qt-based. Some KDE settings are below.
* **Graphic editors** - [gwenview](//kde.org/applications/graphics/gwenview/ "Gwenview Homepage") is used for viewing images, [kolourpaint](//kde.org/applications/graphics/kolourpaint/ "Kolourpaint Homepage") is used for simple editing pixel images, [gimp](//www.gimp.org/ "Gimp Homepage") (without plugins, since they are not needed for me) - for editing and [inkskape](//www.inkscape.org/ "Inkskape Homepage") is used as editor of vector graphics.
* **Browser** - I use Firefox. Some Firefox settings are below. Chromium is used as additional browser, elinks is used as console browser.
* **IM client** is [qutIM](//qutim.org "Qutim Homepage"). It is a cross-platform, multiprotocol and full featured client. [Kopete](//kde.org/applications/internet/kopete/ "Kopete Homepage"), which I used before it, crashes, does not work correctly and does not work normally with codepage. Also I don't use a console client since I use a tablet IM. And I use Skype for skype obviously.
* **Mail client** is [kmail](//kde.org/applications/internet/kmail/ "Kmail Homepage"). It is a full featured client (and I use most of them), looks pretty and it is easy to use. If it will be DE-undepended it will be better.
* **IRC client** is [konversation](//konversation.kde.org/ "Konversation Homepage"). It is a simple IRC client. Though as far as I remember qutIM also supports IRC protocol, I prefre to use a special IRC client.

And command line and scripts written on bash are used too.
* **Office**: [Kingsoft Office](//wps-community.org/ "KO Homepage") is used as alternative of Microsoft Office; it has no any feature, but it looks normally, it is qt-based and it is said that it has a good support for standart formats. (Linux version has an alfa stage.) [Kile](//kile.sourceforge.net/ "Kile Homepage") is used as LaTeX frontend.

In my case I will use `_arguments` command, which require a specific format of variables: `FLAG[description]:MESSAGE:ACTION`. The last two fields are not required and, as you will see below, are not needed in some cases. If you want to add two flags for an action (short and long format), then the format is a little bit complicated: `{(FLAG_2)FLAG_1,(FLAG_1)FLAG_2}[description]:MESSAGE:ACTION`.

In this tutorial `ACTION` will be following: `->STATE`.
