Let’s try dwm — dynamic window manager
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
If you like efficiency and minimalism, and are looking for a new window manager for your Linux desktop, you should try _dwm_ — dynamic window manager. Written in under 2000 standard lines of code, dwm is extremely fast yet powerful and highly customizable window manager.
|
||||
|
||||
You can dynamically choose between tiling, monocle and floating layouts, organize your windows into multiple workspaces using tags, and quickly navigate through using keyboard shortcuts. This article helps you get started using dwm.
|
||||
|
||||
## **Installation**
|
||||
|
||||
To install dwm on Fedora, run:
|
||||
|
||||
```
|
||||
$ sudo dnf install dwm dwm-user
|
||||
```
|
||||
|
||||
The _dwm_ package installs the window manager itself, and the _dwm-user_ package significantly simplifies configuration which will be explained later in this article.
|
||||
|
||||
Additionally, to be able to lock the screen when needed, we’ll also install _slock_ — a simple X display locker.
|
||||
|
||||
```
|
||||
$ sudo dnf install slock
|
||||
```
|
||||
|
||||
However, you can use a different one based on your personal preference.
|
||||
|
||||
## **Quick start**
|
||||
|
||||
To start dwm, choose the _dwm-user_ option on the login screen.
|
||||
|
||||
![][2]
|
||||
|
||||
After you log in, you’ll see a very simple desktop. In fact, the only thing there will be a bar at the top listing our nine tags that represent workspaces and a _[]=_ symbol that represents the layout of your windows.
|
||||
|
||||
### Launching applications
|
||||
|
||||
Before looking into the layouts, first launch some applications so you can play with the layouts as you go. Apps can be started by pressing _Alt+p_ and typing the name of the app followed by _Enter_. There’s also a shortcut _Alt+Shift+Enter_ for opening a terminal.
|
||||
|
||||
Now that some apps are running, have a look at the layouts.
|
||||
|
||||
### Layouts
|
||||
|
||||
There are three layouts available by default: the tiling layout, the monocle layout, and the floating layout.
|
||||
|
||||
The tiling layout, represented by _[]=_ on the bar, organizes windows into two main areas: master on the left, and stack on the right. You can activate the tiling layout by pressing _Alt+t._
|
||||
|
||||
![][3]
|
||||
|
||||
The idea behind the tiling layout is that you have your primary window in the master area while still seeing the other ones in the stack. You can quickly switch between them as needed.
|
||||
|
||||
To swap windows between the two areas, hover your mouse over one in the stack area and press _Alt+Enter_ to swap it with the one in the master area.
|
||||
|
||||
![][4]
|
||||
|
||||
The monocle layout, represented by _[N]_ on the top bar, makes your primary window take the whole screen. You can switch to it by pressing _Alt+m_.
|
||||
|
||||
Finally, the floating layout lets you move and resize your windows freely. The shortcut for it is _Alt+f_ and the symbol on the top bar is _> <>_.
|
||||
|
||||
### Workspaces and tags
|
||||
|
||||
Each window is assigned to a tag (1-9) listed at the top bar. To view a specific tag, either click on its number using your mouse or press _Alt+1..9._ You can even view multiple tags at once by clicking on their number using the secondary mouse button.
|
||||
|
||||
Windows can be moved between different tags by highlighting them using your mouse, and pressing _Alt+Shift+1..9._
|
||||
|
||||
## **Configuration**
|
||||
|
||||
To make dwm as minimalistic as possible, it doesn’t use typical configuration files. Instead, you modify a C header file representing the configuration, and recompile it. But don’t worry, in Fedora it’s as simple as just editing one file in your home directory and everything else happens in the background thanks to the _dwm-user_ package provided by the maintainer in Fedora.
|
||||
|
||||
First, you need to copy the file into your home directory using a command similar to the following:
|
||||
|
||||
```
|
||||
$ mkdir ~/.dwm
|
||||
$ cp /usr/src/dwm-VERSION-RELEASE/config.def.h ~/.dwm/config.h
|
||||
```
|
||||
|
||||
You can get the exact path by running _man dwm-start._
|
||||
|
||||
Second, just edit the _~/.dwm/config.h_ file. As an example, let’s configure a new shortcut to lock the screen by pressing _Alt+Shift+L_.
|
||||
|
||||
Considering we’ve installed the _slock_ package mentioned earlier in this post, we need to add the following two lines into the file to make it work:
|
||||
|
||||
Under the _/* commands */_ comment, add:
|
||||
|
||||
```
|
||||
static const char *slockcmd[] = { "slock", NULL };
|
||||
```
|
||||
|
||||
And the following line into _static Key keys[]_ :
|
||||
|
||||
```
|
||||
{ MODKEY|ShiftMask, XK_l, spawn, {.v = slockcmd } },
|
||||
```
|
||||
|
||||
In the end, it should look like as follows: (added lines are highlighted)
|
||||
|
||||
```
|
||||
...
|
||||
/* commands */
|
||||
static char dmenumon[2] = "0"; /* component of dmenucmd, manipulated in spawn() */
|
||||
static const char *dmenucmd[] = { "dmenu_run", "-m", dmenumon, "-fn", dmenufont, "-nb", normbgcolor, "-nf", normfgcolor, "-sb", selbgcolor, "-sf", selfgcolor, NULL };
|
||||
static const char *termcmd[] = { "st", NULL };
|
||||
static const char *slockcmd[] = { "slock", NULL };
|
||||
|
||||
static Key keys[] = {
|
||||
/* modifier key function argument */
|
||||
{ MODKEY|ShiftMask, XK_l, spawn, {.v = slockcmd } },
|
||||
{ MODKEY, XK_p, spawn, {.v = dmenucmd } },
|
||||
{ MODKEY|ShiftMask, XK_Return, spawn, {.v = termcmd } },
|
||||
...
|
||||
```
|
||||
|
||||
Save the file.
|
||||
|
||||
Finally, just log out by pressing _Alt+Shift+q_ and log in again. The scripts provided by the _dwm-user_ package will recognize that you have changed the _config.h_ file in your home directory and recompile dwm on login. And becuse dwm is so tiny, it’s fast enough you won’t even notice it.
|
||||
|
||||
You can try locking your screen now by pressing _Alt+Shift+L_ , and then logging back in again by typing your password and pressing enter.
|
||||
|
||||
## **Conclusion**
|
||||
|
||||
If you like minimalism and want a very fast yet powerful window manager, dwm might be just what you’ve been looking for. However, it probably isn’t for beginners. There might be a lot of additional configuration you’ll need to do in order to make it just as you like it.

试试动态窗口管理器 dwm 吧
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
如果你崇尚效率和极简主义，并且正在为你的 Linux 桌面寻找新的窗口管理器，那么你应该尝试一下<ruby>动态窗口管理器<rt>dynamic window manager</rt></ruby> dwm。以不到 2000 标准行的代码写就的 dwm，是一个速度极快而功能强大，且可高度定制的窗口管理器。
|
||||
|
||||
你可以在平铺、单片和浮动布局之间动态选择，使用标签将窗口组织到多个工作区，并使用键盘快捷键快速导航。本文将帮助你开始使用 dwm。
|
||||
|
||||
### 安装
|
||||
|
||||
要在 Fedora 上安装 dwm，运行：
|
||||
|
||||
```
|
||||
$ sudo dnf install dwm dwm-user
|
||||
```
|
||||
|
||||
`dwm` 包会安装窗口管理器本身，`dwm-user` 包显著简化了配置，本文稍后将对此进行说明。
|
||||
|
||||
此外，为了能够在需要时锁定屏幕，我们还将安装 `slock`，这是一个简单的 X 显示锁屏。
|
||||
|
||||
```
|
||||
$ sudo dnf install slock
|
||||
```
|
||||
|
||||
当然，你可以根据你的个人喜好使用其它的锁屏。
|
||||
|
||||
### 快速入门
|
||||
|
||||
要启动 dwm，在登录屏选择 “dwm-user” 选项。
|
||||
|
||||
![][2]
|
||||
|
||||
登录后，你将看到一个非常简单的桌面。事实上，顶部唯一的一个面板列出了代表工作空间的 9 个标签和一个代表窗户布局的 `[]=` 符号。
|
||||
|
||||
#### 启动应用
|
||||
|
||||
在查看布局之前，首先启动一些应用程序，以便你可以随时使用布局。可以通过按 `Alt+p` 并键入应用程序的名称，然后回车来启动应用程序。还有一个快捷键 `Alt+Shift+Enter` 用于打开终端。
|
||||
|
||||
现在有一些应用程序正在运行了，请查看布局。
|
||||
|
||||
#### 布局
|
||||
|
||||
默认情况下有三种布局：平铺布局，单片布局和浮动布局。
|
||||
|
||||
平铺布局由条形图上的 `[]=` 表示，它将窗口组织为两个主要区域：左侧为主区域，右侧为堆叠区。你可以按 `Alt+t` 激活平铺布局。
|
||||
|
||||
![][3]
|
||||
|
||||
平铺布局背后的想法是，主窗口放在主区域中，同时仍然可以看到堆叠区中的其他窗口。你可以根据需要在它们之间快速切换。
|
||||
|
||||
要在两个区域之间交换窗口，请将鼠标悬停在堆叠区中的一个窗口上，然后按 `Alt+Enter` 将其与主区域中的窗口交换。
|
||||
|
||||
![][4]
|
||||
|
||||
单片布局由顶部栏上的 `[N]` 表示，可以使你的主窗口占据整个屏幕。你可以按 `Alt+m` 切换到它。
|
||||
|
||||
最后，浮动布局可让你自由移动和调整窗口大小。它的快捷方式是 `Alt+f`，顶栏上的符号是 `><>`。
|
||||
|
||||
#### 工作区和标签
|
||||
|
||||
每个窗口都分配了一个顶部栏中列出的标签（1-9）。要查看特定标签，请使用鼠标单击其编号或按 `Alt+1..9`。你甚至可以使用鼠标右键单击其编号，一次查看多个标签。
|
||||
|
||||
通过使用鼠标突出显示后，并按 `Alt+Shift+1..9`，窗口可以在不同标签之间移动。
|
||||
|
||||
### 配置
|
||||
|
||||
为了使 dwm 尽可能简约，它不使用典型的配置文件。而是你需要修改代表配置的 C 语言头文件，并重新编译它。但是不要担心，在 Fedora 中你只需要简单地编辑主目录中的一个文件，而其他一切都会在后台发生，这要归功于 Fedora 的维护者提供的 `dwm-user` 包。
|
||||
|
||||
首先，你需要使用类似于以下的命令将文件复制到主目录中：
|
||||
|
||||
```
|
||||
$ mkdir ~/.dwm
|
||||
$ cp /usr/src/dwm-VERSION-RELEASE/config.def.h ~/.dwm/config.h
|
||||
```
|
||||
|
||||
你可以通过运行 `man dwm-start` 来获取确切的路径。
|
||||
|
||||
其次，只需编辑 `~/.dwm/config.h` 文件。例如，让我们配置一个新的快捷方式：通过按 `Alt+Shift+L` 来锁定屏幕。
|
||||
|
||||
考虑到我们已经安装了本文前面提到的 `slock` 包，我们需要在文件中添加以下两行以使其工作：
|
||||
|
||||
在 `/* commands */` 注释下，添加：
|
||||
|
||||
```
|
||||
static const char *slockcmd[] = { "slock", NULL };
|
||||
```
|
||||
|
||||
添加下列行到 `static Key keys[]` 中：
|
||||
|
||||
```
|
||||
{ MODKEY|ShiftMask, XK_l, spawn, {.v = slockcmd } },
|
||||
```
|
||||
|
||||
最终，它应该看起来如下：
|
||||
|
||||
```
|
||||
...
|
||||
/* commands */
|
||||
static char dmenumon[2] = "0"; /* component of dmenucmd, manipulated in spawn() */
|
||||
static const char *dmenucmd[] = { "dmenu_run", "-m", dmenumon, "-fn", dmenufont, "-nb", normbgcolor, "-nf", normfgcolor, "-sb", selbgcolor, "-sf", selfgcolor, NULL };
|
||||
static const char *termcmd[] = { "st", NULL };
|
||||
static const char *slockcmd[] = { "slock", NULL };
|
||||
|
||||
static Key keys[] = {
|
||||
/* modifier key function argument */
|
||||
{ MODKEY|ShiftMask, XK_l, spawn, {.v = slockcmd } },
|
||||
{ MODKEY, XK_p, spawn, {.v = dmenucmd } },
|
||||
{ MODKEY|ShiftMask, XK_Return, spawn, {.v = termcmd } },
|
||||
...
|
||||
```
|
||||
|
||||
保存文件。
|
||||
|
||||
最后，按 `Alt+Shift+q` 注销，然后重新登录。`dwm-user` 包提供的脚本将识别你已更改主目录中的`config.h` 文件，并会在登录时重新编译 dwm。因为 dwm 非常小，它快到你甚至都不会注意到它重新编译了。
|
||||
|
||||
你现在可以尝试按 `Alt+Shift+L` 锁定屏幕，然后输入密码并按回车键再次登录。
|
||||
|
||||
### 总结
|
||||
|
||||
如果你崇尚极简主义并想要一个非常快速而功能强大的窗口管理器，dwm 可能正是你一直在寻找的。但是，它可能不适合初学者，你可能需要做许多其他配置才能按照你的喜好进行配置。
