dust

Magic fairy dust for Pixie.

Provides tooling around pixie, e.g. a nicer repl, running tests and fetching dependencies.

Usage

• dust or dust repl to start a REPL

• dust test to run the tests

• dust run to run code in a file

• all commands:

  $ dust help
  Usage: dust <cmd> <options>
  
  Available commands:
  get-deps  Download the dependencies of the current project.
  deps      List the dependencies and their versions of the current project.
  repl      Start a REPL in the current project.
  run       Run the code in the given file.
  doc       Show function documentation. Broaden search using -all
  load-path Print the load path of the current project.
  test      Run the tests of the current project.
  help      Display the help
  describe  Describe the current project.
  

Project definition

dust reads its settings from a per-project project.edn file. In that file one configures the name, version, dependencies and other metadata about the project:

{:name dust
 :version "0.1.0-alpha"
 :description "Magic fairy dust for Pixie"
 :dependencies [[heyLu/hiccup.pxi "0.1.0-alpha"]]}

With such a project definition you can run dust get-deps to fetch the dependencies of the project and dust will set up the load-paths var in Pixie so that the namespaces are available in the repl or when running programs:

$ dust get-deps
Downloading heyLu/hiccup.pxi
$ dust repl
Pixie 0.1 - Interactive REPL
(linux, gcc)
:exit-repl or Ctrl-D to quit
----------------------------
user => (use 'hiccup.core)
nil
user => (html [:span#foo.bar.baz "HOORAY!"])
"<span class="bar baz" id="foo">HOORAY!</span>"
user => @load-paths
["/home/lu/t/pixie/pixie" "." "deps/heyLu/hiccup.pxi/src"]

Installation

• install Pixie
• ln -s <path-to-pixie>/pixie-vm /usr/bin/pixie-vm (or really anywhere else in $PATH)
• git clone git://github.com/pixie-lang/dust
• ln -s <path-to-dust>/dust /usr/bin/dust (or really anywhere else in $PATH)

For an improved REPL with history and line-editing you'll need to install rlwrap.

Contributions welcome!

Some ideas:

• dust doc, probably using something like this
• dependency improvements:
  • fetch dependencies from paths inside repositories, maybe via a :path "sub/dir" option
