Mission control in GNU Emacs

 


Mission control or desktop/window overview in GNU Emacs. This is an Emacs buffer showing some images in a fullscreen frame. The first line shows images of workspaces. The rest are images of active windows in current workspace. It uses the following external tools:

  • wmctrl - For switching applications and workspaces
  • xdotool - For getting id of active window
  • xwd - For taking screenshots in XWD format
  • ffmpeg - For scaling and converting XWD to PNG format

Install these essential tools in your system.

 $ sudo apt install wmctrl xdotool xwd ffmpeg

Load library task.el

 (require 'task)

Run M-x task-view or M-x task-view-fullscreen . Use mouse to select, g to group, G to ungroup, m to start a move operation and ESC to cancel. Use double click to activate a window or desktop. Press q or RET to exit. Pro Tip: You can select multiple windows.

Note: xfdashboard can also serve the purpose as an external application. Additionally, it provides live preview of running applications.

Mozilla Readability in GNU Emacs

Image
  Output using Readability (left) and original eww (right)   Mozilla Readability is a standalone version of the readability library used for Firefox Reader View . A simple hack to eww can bring the same feature in GNU Emacs. ( Note: eww already has a readable mode. This is just an alternative. Updated the post to reflect the same.)   - Install NodeJS   - Install npm modules. npm install @mozilla/readability jsdom   - Create a file readability.js with following content. Note the file location. var { Readability } = require('@mozilla/readability'); var { JSDOM } = require('jsdom'); var fs = require("fs"); var str = fs.readFileSync(process.stdin.fd).toString(); var doc = new JSDOM(str); var reader = new Readability(doc.window.document); var article = reader.parse(); console.log(article.content);     - Modify the following function to use the file location noted above . Evaluate the function. (defun mozilla-readability (start end)   (shell-command-o...

Data Visualization with GNU Emacs

Image
    GNU Emacs can be used for quick data visualization in combination with Gnuplot. When you have some data and you want to visualize what the correlation looks like, this command comes in handy. No need for any setup - no data file and no Gnuplot script. The command below uses some sensible defaults for trivial cases. If the first line contains string label, the same is used as a key label for the value and/or axes' names as appropriate. If there's a single column of data, it is used as Y value. If there's more than one column, first column is used as X value and other columns are plotted along Y-axis. Takes care of comma or whitespace separator. Note: The latest version of the code is available at the end of the post. Options available in latest version   - Install gnuplot executable and gnuplot Elisp package . - Evaluate the defun ( C-M-x ). - Select a data range using rectangle command copy-rectangle-as-kill (C-x r M-w). - Run M-x  gnuplot-rectangle. This open...
