Traverse complex JSON structures with live feedback
Rationale
This is Alain’s talk from EmacsConf 2020: https://emacsconf.org/2020/schedule/25/
Complementary blog post and video: https://200ok.ch/posts/2020-11-30_emacsconf_traverse_complex_json_structures_with_live_feedback_with_counseljq
Abstract
If you are working with complex nested JSON structures, you are probably familiar with jq which is like sed for JSON data and great at what it does. However, being a command-line tool like sed, the feedback for writing queries and seeing their results is a discrete process and not live.
When working with Emacs, we are used to good auto-completion and live feedback. Formerly, this was mostly done with static input, but with modern completion frameworks like Ivy and Counsel, this can be done with dynamic inputs, as well.
counsel-jq is a package with which you can quickly test queries and
traverse a complex JSON structure whilst having live feedback. Just
call M-x counsel-jq in a buffer containing JSON, then start writing
your jq query string and see the output appear live in the message
area. Whenever you’re happy, hit RET and the results will be displayed
to you in the buffer *jq-json*.
In this lightning talk, I’ll give a quick overview on how to use counsel-jq and how to build similar completion functionality.
Introduction to organice
Rationale
This is a pre-recorded talk of Alain for the EmacsConf 2019 on November 2nd 2019.
Abstract
Are you a fan of Org mode? If so, you probably want to have access to your Org files at any time - even when away from your computer. Or maybe you want to collaborate with other people who are not Emacs users themselves.
organice is the solution for that!
It is an implementation of Org mode without the dependency of Emacs. It is built for mobile and desktop browsers and syncs with Dropbox and Google Drive.
Please find the code of organice here: https://github.com/200ok-ch/organice

The talk has been pre-recorded and is available on Youtube: https://www.youtube.com/watch?v=aQKc0hcFXCk

Introduction to ClojureScript and Functional Programming
Rationale
This is a talk Alain gave at the Web Zueri Meetup in Zurich, Switzerland on July 24, 2018.
Abstract
The complexity of software is growing at an exponential rate. The biggest challenge is the growing complexity of dynamic state which makes it hard to reason about a system. There are many paradigms aiming to ease the situation. To reduce incidental complexity “Functional Programming” and “Code Hot-Reloading” have become much talked about topics in the web development community.
In this talk, Alain will show you how to supercharge your development setup with true code hot-reloading in a truly functional programming language.
Recording
To be announced. The Web Zueri crew made a recording and will publish it on their Youtube channel.

Play Emacs like an instrument
Rationale
This is a talk Alain gave at the Clojure Meetup in Zurich, Switzerland on April 23, 2018.
Abstract
Lean back and relax while enjoying a deep dive into the wonderful world of the Emacs editor. Emacs renaissance came with the advent of Clojure and undoubtedly is the most popular editor among Clojurians today. Of course there is a lot more you can do with Emacs, but much like playing an instrument, great skill only comes with practice.
You neither need to be an Emacs user nor a Clojure Programmer and neither do you need to contemplate about becoming one either to enjoy this talk. Much like you don’t become a professional musician by attending a concert, but it might very well be inspiring.
