• About

  Guix-Jupyter is a Jupyter “kernel” that interprets software deployment
  annotations, thereby making sure computations run in the right
  software environment.  Cells execute in isolated containers, which
  furthers reduces the risks of non-reproducibility.  Input data can be
  fetched by using an extra annotation, which must include the expected
  hash of the data.

• Excerpt from the ‘NEWS’ file

  * Changes in 0.2.1 (since 0.2.0)

  ** Bug fix

     Previously Guix-Jupyter would store container data in
     /tmp/guix-kernel, which prevented multiple users from running it on
     the same machine.  It now uses mkdtemp(3) to create that directory.

  * Changes in 0.2.0 (since 0.1.0)

  ** New functionality

  *** New ‘;;guix describe’ magic command

      Like the ‘guix describe’ shell command, it returns the currently-used

  *** New ‘;;guix search’ magic command

  *** ‘;;guix pin’ and ‘;;guix describe’ output includes links to VCS history

      This allows you to see the version-control system (VCS) history
      leading to the channel commit you’re using.

  *** Report build and download progress in the notebook

      When Guix starts downloading or building things, for instance in
      response to an environment creation via ‘;;guix environment’, a
      transient line in the notebook displays what’s being built or

  *** Guile kernel can display SVG pictures

      The built-in Guile kernel now returns SVG for images produced by
      ‘guile-picture-language’ (see

  ** Bug fixes

  *** Gracefully handle package-not-found errors in ‘;;guix environment’

  *** Properly complete ‘;;guix’ magic commands

  *** Fix potential hang in ‘;;guix pin’

  *** Gracefully handle ‘;;guix download’ syntax errors
