Here are a couple of mini-tutorials on using two Emacs packages. They’re both pretty short so I’ve combined them into a single post. In the first, Yuri Tricys presents some configurations and packages to customize Olivetti-mode. He shows how to adjust the margins, toggle the fringe on and off, and configure wrap and fill columns, He also shows using the highlight-numbers and the stripes packages.
Unfortunately, Tricys doesn’t provide any examples of the output but most of his configurations are self explanatory. If you’re a writer who uses or is considering using Olivetti-mode, take a quick look at Tricys’ post.
The second tutorial is by Franco Pasut and considers using expand-region with LaTeX. Many Irreal readers are probably familiar with expand-region from using it with their programming buffers but it’s also useful for dealing with LaTeX source. Pasut has a series of animated GIFs that show it in action. Judging from the GIFs, expand-region has some shortcomings when used with LaTeX as compared to other languages. For example, I’d expect the highlighting to go from word to sentence and then to paragraph.
Of course, Magnar anticipated that people would want to add capabilities and made that easy. If you’re really interested in using expand-region with LaTeX, you should look into adding the features you need.
