• What is the best way to avoid getting "Emacs Pinky"?

  - by Ray Vega

  I just started using GNU Emacs as my text editor and I am concerned about getting afflicted with "Emacs Pinky" by having to constantly press the control key with my pinky finger as is required when using Emacs. How can I avoid potentially getting this type of repetitive strain injury?

• Why are C, C++, and LISP so prevalent in embedded devices and robots?

  - by David

  It seems that the software language skills most sought for embedded devices and robots are C, C++, and LISP. Why haven't more recent languages made inroads into these applications? For example, Erlang would seem particularly well-suited to robotic applications, since it makes concurrent programming easier and allows hot swapping of code. Python…

• Why would I use Dropbox *and* Git for my Emacs initialization file?

  - by Michiel Borkent

  I hear a lot of Emacs users have their init file under git version control and sync the git repository over Dropbox, when they run Emacs on multiple systems. Why would you use git in this situation exactly? Usually checking which system you're on and which things to load and set depending on that can happen in one and the same init file for all…

• Is there a good extension for SVN in Emacs?

  - by allyourcode

  I've tried psvn.el, but the command to diff the file you're currently looking at is just hideous: M-x svn-file-show-svn-diff. I tried installing vc-svn.el, but couldn't get that working on my version of Emacs: GNU Emacs 21.3.1 (i386-mingw-nt5.1.2600) of 2004-03-10 on NYAUMO. The emacs wiki page, which mainly focuses on vc-svn.el, seems to be…

• Would Lisp be extremely difficult for a new(ish) programmer to learn?

  - by Rubber Duchy

  I've got a little experience with Python (enough to where I can do if/else/elif and some random number generation), but I've always had a weird fascination with the Lisp languages. I downloaded some scheme source code to look at the syntax but it was pretty much gibberish to me. For a programmer with only a little programming experience…

• C# Dev - I've tried Lisps, but I don't get it.

  - by Jonathan Mitchem

  After a few months of learning about and playing with lisps, both CL and a bit of Clojure, I'm still not seeing a compelling reason to write anything in it instead of C#. I would really like some compelling reasons, or for someone to point out that I'm missing something really big. The strengths of a Lisp (per my research): Compact,…

• s expression representation for c

  - by wirrbel

  Experimenting with various lisps lately (clojure especially) i have wondered if there are any s expression based representations of (subsets) of c, so you could use lisp/closure to write macros and then convert the s-expression c tree to pure c. I am not asking for a to-c-compilers of lisp/scheme/clojure but more of using lisps to…

• What are the differences between Bigloo and ECL from an embedding standpoint? [migrated]

  - by Pubby

  I've been looking to embed Lisp in some C++ code. Two options I'm interested in is Bigloo Scheme and ECL (Common Lisp). Reading through the docs they seem to support a very similar feature set. Obviously Bigloo is Scheme and ECL is CLisp, but what other differences do they have? In particular I'm interested in the…

• Implementing `let` without using a macro

  - by Matt Fenwick

  I'm learning Lisp, and I've just gotten to let, which I don't quite understand (the implementation of). A common definition for it is given in terms of lambda as a macro. However, nowhere have I seen that let must be implemented as a macro or in terms of lambda. Is it possible to define let without using a…

• What's a good unit test framework for Common Lisp projects?

  - by Lorenzo V.

  I need to write a unit test suite for a project I am developing in my spare time. Being a CL newbie I was overwhelmed by the amount of choices for a CL implementation, I spent quite some time to choose one. Now I am facing exactly the same thing with unit test frameworks. A quick glance at…

• Can I create directories that don't exist while creating a new file in emacs?

  - by Jim

  In emacs, I create a file by visiting it with C-x C-f. Let's say I'd like to create /home/myself/new_directory/file.txt. If new_directory does not exist yet, is there a way to have it get created during the creation of file.txt without any extra steps? (I'm thinking of something like using…

• Is there a way to specify minimum minibuffer/echo area size in emacs?

  - by Trevor Alexander

  I am running Emacs 24, and due to a separate issue, my input method displays input candidates in the minibuffer regardless of how I set its options. That would not be such a problem if the minibuffer did not resize from height 2 (when displaying candidates) to height 1 (when not),…

• Is there an equivalent to Lisp's "runtime" primitive in Scheme?

  - by Bill the Lizard

  According to SICP section 1.2.6, exercise 1.22: Most Lisp implementations include a primitive called runtime that returns an integer that specifies the amount of time the system has been running (measured, for example, in microseconds). I'm using DrScheme, where runtime…
