    Hi Sacha! Thanks so much for sharing this!

    Would it be possible that (at some point) you shared the corresponding Emacs packages involved in the different tasks you’ve used Emacs for? I’d be really interested in learning about them!

    Thanks so much :-)

    Good idea. =) I’ve been thinking about writing short descriptions / tutorials for each of them. Let’s see where I go with that project!

  • Martin

    Quite impressive proof that there’s nothing emacs cannot do for you ;-)

    By the way what happened to your Emacs book project?

  • http://sachachua.com Sacha Chua

    Martin: I realized that writing cool little Emacs snippets that you can use to improve this contrib package often led to the maintainers of those contrib packages folding those nifty ideas into the code. This is a good thing, but it made it very hard to write for a moving target! I’ve been playing around with the idea of writing an Emacs biography though – telling stories about what people use Emacs for and how they learned about those parts… Is that something you might be interested in?

  • Vee

    Nice! You are true emacs guru!
    I have been using emacs a lot, and I have been learning from your blog to use emacs to do even more tasks. Now I use emacs everyday, for programming, doing various planning, taking meeting minutes, etc.
    Ya, it would be nice if you can also write down how you use emacs to manage each task, even just briefly mention the package/method used. E.g., use org-mode, or with some elisp package, etc. :)
    Anyway, thanks so much for sharing the list!

  • Salfran

    Wow Sacha, truly great! Could you please tell me if you accomplish all of that with the .emacs file you published recently? I’m trying to use emacs as a do-it-all tool.

    Brainstorming, outlining, and mindmapping

    If you could share how you use emacs for mind mapping, I sure would appreciate it.

    Be kind – I’ve only been using emacs for a year, I’m still new to it.

    Sacha: it’s interesting to learn how other people use Emacs but I don’t mind too much how they learned it. I guess for many people it will be something like “I saw that an Sacha’s blog” ;-). I second Andrea’s idea to have a small description for each of those packages.
