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.
* **Torrent client** is [transmission](//www.transmissionbt.com/ "Transmission Homepage") with Qt5 interface (it has gtk interface too). It is also used for server but without GUI.
* **Video player** is [mpv](//mpv.io/ "Mpv Homepage"), since mplayer died and mplayer2 was born deadborn. Graphical frontend are not needed.
* **Audio player** is [qmmp](//qmmp.ylsoftware.com/ "Qmmp Homepage"). It is a good winamp-like player. Flick of the wrist you may make a handy interface for it (simpleui).
* **Audio/video editors**: [kdenlive](//kde-apps.org/content/show.php?content=29024 "Kdenlive Homepage") is used as video editor, [soundkonverter](//kde-apps.org/content/show.php?content=29024) is used as audio editor, [easytag](//wiki.gnome.org/Apps/EasyTAG "Easytag Homepage") is used for editing audio tags (unfortunately, it is a gtk-based, but I didn't find a better tool for it). 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. [Okular](//kde.org/applications/graphics/okular/ "Okular Homepage") is used as document viewer. And I use [GoldenDict](//goldendict.org/ "GoldenDict Homepage") as dictionary.
* **Editors**: [kwrite](//www.kde.org/applications/utilities/kwrite/ "Kwrite Homepage") is used as a simple text editor, [kate](//www.kde.org/applications/utilities/kate/ "Kate Homepage") (and [cpp-helper](//zaufi.github.io/kate-cpp-helper-plugin.html "Plugin Homepage") plugin) is used as advanced text editor. And of course I use vim in console.
* **Scientific soft**. Chemical visualizers are [vmd](//www.ks.uiuc.edu/Research/vmd/ "VMD Homepage"), [chimera](//www.cgl.ucsf.edu/chimera/ "Chimera Homepage") and [pymol](//pymol.org/ "Pymol Homepage"). Physics simulator is [step](//kde.org/applications/education/step/ "Step Homepage"). Calculator is [kalgebra](//kde.org/applications/education/kalgebra/ "Kalgebra Homepage") and console [ipython](//ipython.org/ "ipython Homepage"). [Qtiplot](//qtiplot.com/ "Qtiplot Homepage") is used for drawing graphs and data analysis (scidavis, which is its fork, unfortunately, is half-dead), [grace](//plasma-gate.weizmann.ac.il/Grace/ "Grace Homepage") is used for only drawing graphs. [Chemtool](//ruby.chemie.uni-freiburg.de/~martin/chemtool/chemtool.html "Chemtool Homepage") is used as alternative of ChemDraw.
* **System applications**. File manager is [dolphin](//kde.org/applications/system/dolphin/ "Dolphin Homepage"), [doublecmd](//doublecmd.sourceforge.net/ "Doublecmd Homepage") is used as twin-panel manager. Terminal emulators are [yakuake](//yakuake.kde.org/ "Yakuake Homepage") and [urxvt](//software.schmorp.de/pkg/rxvt-unicode.html "Urxvt Homepage") (as windowed emulator). Archiver graphical interface is [ark](//kde.org/applications/utilities/ark/ "Ark Homepage").
* **Shell** is zshrc and nothing else. You may find a small description of my

* **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.
* **Torrent client** is [transmission](//www.transmissionbt.com/ "Transmission

server but without GUI.
