From 8146021a2ea4130cfb0d2bf846b451ec538b1bb6 Mon Sep 17 00:00:00 2001 From: philw Date: Tue, 15 Apr 2025 01:41:05 +0200 Subject: Refactor the project Refactored core logic to improve readability and maintainability. Documented the 'transient.c' file to provide clear explanations of its purpose and functions. Updated the 'util.c' file with necessary comments and improvements to existing code. Documented the 'util.h' header file to clarify function prototypes and usage. This update should improve the overall code quality and make it easier for future development.

It manages windows in tiled, monocle +and floating layouts. Either layout can be applied dynamically, optimising the +environment for the application in use and the task performed. +.P +In tiled layouts windows are managed in a master and stacking area. The master +area on the left contains one window by default, and the stacking area on the +right contains all other windows. The number of master area windows can be +adjusted from zero to an arbitrary number. In monocle layout all windows are +maximised to the screen size. In floating layout windows can be resized and +moved freely. Dialog windows are always managed floating, regardless of the +layout applied. +.P +Windows are grouped by tags. Each window can be tagged with one or multiple +tags. Selecting certain tags displays all windows with these tags. +.P +Each screen contains a small status bar which displays all available tags, the +layout, the title of the focused window, and the text read from the root window +name property, if the screen is focused. A floating window is indicated with an +empty square and a maximised floating window is indicated with a filled square +before the windows title. The selected tags are indicated with a different +color. The tags of the focused window are indicated with a filled square in the +top left corner. The tags which are applied to one or more windows are +indicated with an empty square in the top left corner. +.P +dwm draws a small border around windows to indicate the focus state. +.SH OPTIONS +.TP +.B \-v +prints version information to stderr, then exits. +.SH USAGE +.SS Status bar +.TP +.B X root window name +is read and displayed in the status text area.

It manages windows in tiled, monocle -and floating layouts. Either layout can be applied dynamically, optimising the -environment for the application in use and the task performed. -.P -In tiled layouts windows are managed in a master and stacking area. The master -area on the left contains one window by default, and the stacking area on the -right contains all other windows. The number of master area windows can be -adjusted from zero to an arbitrary number. In monocle layout all windows are -maximised to the screen size. In floating layout windows can be resized and -moved freely. Dialog windows are always managed floating, regardless of the -layout applied. -.P -Windows are grouped by tags. Each window can be tagged with one or multiple -tags. Selecting certain tags displays all windows with these tags. -.P -Each screen contains a small status bar which displays all available tags, the -layout, the title of the focused window, and the text read from the root window -name property, if the screen is focused. A floating window is indicated with an -empty square and a maximised floating window is indicated with a filled square -before the windows title. The selected tags are indicated with a different -color. The tags of the focused window are indicated with a filled square in the -top left corner. The tags which are applied to one or more windows are -indicated with an empty square in the top left corner. -.P -dwm draws a small border around windows to indicate the focus state. -.SH OPTIONS -.TP -.B \-v -prints version information to stderr, then exits. -.SH USAGE -.SS Status bar -.TP -.B X root window name -is read and displayed in the status text area. It can be set with the -.BR xsetroot (1) -command. -.TP -.B Button1 -click on a tag label to display all windows with that tag, click on the layout -label toggles between tiled and floating layout. -.TP -.B Button3 -click on a tag label adds/removes all windows with that tag to/from the view. -.TP -.B Mod1\-Button1 -click on a tag label applies that tag to the focused window. -.TP -.B Mod1\-Button3 -click on a tag label adds/removes that tag to/from the focused window. -.SS Keyboard commands -.TP -.B Mod1\-Shift\-Return -Start -.BR st(1). -.TP -.B Mod1\-p -Spawn -.BR dmenu(1) -for launching other programs. -.TP -.B Mod1\-, -Focus previous screen, if any. -.TP -.B Mod1\-. -Focus next screen, if any. -.TP -.B Mod1\-Shift\-, -Send focused window to previous screen, if any. -.TP -.B Mod1\-Shift\-. -Send focused window to next screen, if any. -.TP -.B Mod1\-b -Toggles bar on and off. -.TP -.B Mod1\-t -Sets tiled layout. -.TP -.B Mod1\-f -Sets floating layout. -.TP -.B Mod1\-m -Sets monocle layout. -.TP -.B Mod1\-space -Toggles between current and previous layout. -.TP -.B Mod1\-j -Focus next window. -.TP -.B Mod1\-k -Focus previous window. -.TP -.B Mod1\-i -Increase number of windows in master area. -.TP -.B Mod1\-d -Decrease number of windows in master area. -.TP -.B Mod1\-l -Increase master area size. -.TP -.B Mod1\-h -Decrease master area size. -.TP -.B Mod1\-Return -Zooms/cycles focused window to/from master area (tiled layouts only). -.TP -.B Mod1\-Shift\-c -Close focused window. -.TP -.B Mod1\-Shift\-space -Toggle focused window between tiled and floating state. -.TP -.B Mod1\-Tab -Toggles to the previously selected tags. -.TP -.B Mod1\-Shift\-[1..n] -Apply nth tag to focused window. -.TP -.B Mod1\-Shift\-0 -Apply all tags to focused window. -.TP -.B Mod1\-Control\-Shift\-[1..n] -Add/remove nth tag to/from focused window. -.TP -.B Mod1\-[1..n] -View all windows with nth tag. -.TP -.B Mod1\-0 -View all windows with any tag. -.TP -.B Mod1\-Control\-[1..n] -Add/remove all windows with nth tag to/from the view. -.TP -.B Mod1\-Shift\-q -Quit dwm. -.SS Mouse commands -.TP -.B Mod1\-Button1 -Move focused window while dragging.

This keeps it fast, secure and simple. -.SH SEE ALSO -.BR dmenu (1), -.BR st (1) -.SH ISSUES -Java applications which use the XToolkit/XAWT backend may draw grey windows -only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early -JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds -are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the -environment variable -.BR AWT_TOOLKIT=MToolkit -(to use the older Motif backend instead) or running -.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D -or -.B wmname LG3D -(to pretend that a non-reparenting window manager is running that the -XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable -.BR _JAVA_AWT_WM_NONREPARENTING=1 . -.SH BUGS -Send all bug reports with a patch to hackers@suckless.org. diff --git a/dwm.c b/dwm.c deleted file mode 100644 index 22f228a..0000000 --- a/dwm.c +++ /dev/null @@ -1,2903 +0,0 @@ -/* See LICENSE file for copyright and license details. - * - * dynamic window manager is designed like any other X client as well.
