Style, but some of the layer bindings might be shadowed by the evil key bindings. While you are using the vim editing style if you have some kind of mixed However the emacs editing style is not required. I’d love to be able to demonstrate Vimprint in action by that date.This layer enhances the default commands of Emacs and is primarily intended toīe used with the emacs editing style as it does not change anything in the Vim I’ll be presenting a session on Modelling State Machines with Ragel at Eurucamp this year. If you’d like to #pairwithme on Vimprint, then please get in touch. I’d welcome any help on it that I can get. I’ve found this kind of visualization to be very helpful in debugging Ragel programs. Here’s the state chart visualization of the simple.rl program (created with the command ragel -Vp simple.rl): dot graphs, which can be viewed using Graphviz. Install ragel ( brew install ragel on a mac), then you can compile and run this program: ragel -R simple.rlĪs well as compiling executable Ruby code, Ragel can generate. After all, Vim itself is a finite state machine of sorts.Īs a demonstration, I’ve created a simple.rl ragel program that parses a tiny subset of Vim’s commands. Ragel is a state machine compiler, which seems like a good fit for this problem. With a custom build of Vim using my live-stream-keystrokes branch of MacVim, I can get the realtime stream of keystrokes that I need. Kana Natsuno (one of my Vim heroes) came up with this single-line patch, which disables buffering of the -w option. To create a realtime visualization, I would need a realtime stream of keystrokes. It does this by launching Vim with the -w option: it only writes keystrokes to the specified file when Vim exits. The VimGolf client tracks your keystrokes, and sends them to. I love the way that Vimulator renders and explains keystrokes, but the task of implementing Vim in JavaScript I find daunting. George Brocklehurst from thoughtbot has achieved that with Vimulator, which is a Vim Simulator (as the name suggests) that runs inside the browser. That’s cool! But I want to get these kinds of explanations in realtime. Vimsplain is run as a batch job at the command-line. I want to turn keystrokes into plain English descriptions, and Vimsplain by pafcu is a project that does exactly that. Turning English into keystrokes is the opposite of what I want to do. Check out this demo, where the author completes a VimGolf challenge by talking to his computer. (Let me know if I missed any.) VimSpeak by AshleyF turns spoken English into keystrokes. In researching this topic, I’ve come across a few similar projects that have influenced or inspired me. You can watch the video on Vimeo and refer to the slides on speakerdeck. I gave a presentation on Vimprint at this month’s VimLondon meetup. In addition to showing which keystrokes were pressed, I’d like Vimprint to be able to give a bit of extra context: what does each command do, and from which mode was it triggered? Ultimately, I’d like Vimprint to handle all of Vim’s built-in functionality, and for it to be extensible so that it can be made to understand commands supplied by popular plugins such as surround.vim. My goal is to make Vimprint show all Vim keystrokes in realtime, so that I can use it when teaching Vim. It’s not ideal, but it’s better than nothing! I would love to have a dedicated program for visualizing my keystrokes in Vim, so I’ve started building Vimprint to scratch that itch. Keycastr uses Growl-style notifications to show all keystrokes across all applications, including every letter I type while communicating in a chat room, for example. When I run my Core Vim Masterclasses I use Keycastr to show what I’m doing in realtime. The fact is that I add them by hand in post-production. I sometimes get asked what software I use to reveal the Vim keystrokes in my video tutorials here on.
