   4 Handy Emacs utilities
   5
   6 I've been using Emacs since it was publicly available (1985 or 1986), and have contributed some items which are included with Emacs, notably the [Allout outliner](http://myriadicity.net/software-and-systems/craft/emacs-allout), [icomplete mode](http://www.emacswiki.org/emacs/IcompleteMode), and python-mode's [pdbtrack functionality](http://myriadicity.net/software-and-systems/craft/crafty-hacks#section-1). Like many long-time Emacs users, I've got some personal custom code, some of which I wouldn't do without. Here's some that I particularly like, and think might be useful to others - I hope to include more, as time allows.
   7
   8 * **pdbtrack.el**
   9
  10   Add sensitivity to comint shells so the source file lines are automatically
  11   presented in a separate window when the Python PDB debugger steps to them.
  12
  13   This is derived from the pdb tracking code, which I originally wrote, and
  14   which has been included in (various) official Emacs Python modes. I wanted
  15   a version that I could more easily tweak and maintain, independently of
  16   the python-mode code.
  17
  18   It would eventually be nice to generalize this code, to work for things
  19   like the node.js debugger. We'll see if I (or anyone) ever gets around to
  20   that.
  21
  22 * **poptoshell.el**
  23
  24   I use the emacs shell a lot. This code enables me to streamline and
  25   extend how I can a single one, or multiple ones in a project-oriented
  26   fashion:
  27
  28   * It simplifies getting to the input prompt, by doing the right thing when
  29     I hit the key I have bound to pop-to-shell (I use [M-space], ie
  30     meta-space:
  31   * If the cursor is in a buffer that has no subprocess, pop the window to
  32     the primary shell buffer
  33   * If there is no shell buffer, start one.
  34   * If the cursor is in a buffer which has a process, move the cursor to
  35     the process input point.
  36   * With a universal argument, even if the current buffer has a subprocess,
  37     solicit the name of the target shell buffer - defaulting to the currently
  38     chosen primary one - and pop to that.
  39     * This enables starting an alternate shell buffer, for instance, and/or
  40       switching between the main and alternate ones.
  41     * (The expected name is without the surrounding asterisks, and
  42       completion is done against existing shell buffer names stripped of
  43       their asterisks.)
  44   * With a doubled universal arg, prompt for the target shell buffer and
  45     use the provided name as the ensuing default.
  46
  47   The last few things enable a kind of project-focus mode.  I often have
  48   various shell buffers, each one associated with a project. As I switch
  49   which project is currently my primary focus, I use the double universal
  50   argument to switch which shell buffer is the default. I can still use the
  51   single universal argument to easily switch to any of the shells, but most
  52   easily to my current primary.
