[ANN] Juno-Plus 0.8

I am happy to announce Juno-plus 0.8. This is an Atom’s package that enhances Julia IDE (Juno) by adding some useful buttons and code snippets. Code snippets are also available for VSCode and Sublime.


  • Adding Julia code snippets

There are some cool snippets among those. For example

switch case:

do while:


  • Adding Regex code snippets. This includes the Regex syntax and also some common snippets.

  • Adding Weave code snippets.

  • Adding more buttons. The full list is available in the following.

  • I renamed Juno-Toolbar-Plus to Juno-Plus because I have added more features other than the toolbar.

Atom Installation

Repo: https://github.com/aminya/juno-plus

After installation, if the Julia Client icons are still present, you might need to reload/restart Atom 2 times! (because this package adjusts Julia Client and Tool-bar config settings).

VSCode - Sublime Installation

Converted code snippets are available under snippets_converted folder.


Files and Folders

  • Open Folder - useful for opening and developing a project/package
  • Select Julia working directory


  • Restart Julia (which removes workspace)
  • Erase console
  • Show documentation of selection
  • using Revise

Code Tools:

  • Bookmarks
  • Fold all - Unfold all: useful for code overview
  • Auto Indent Selection (faster than Julia-Client formatting button)


  • Markdown preview: for previewing Readme.md if the package is already installed

Atom utilities:

  • Open Settings
  • Fullscreen
  • Command Palette

Nice work - can I ask why the negation is written as (!).([true, false]) rather than .!([true, false]) or even .![true, false]? I guess the latter might not work as well in the general case but I always thought of .!() as more idiomatic than (!).()

(!).([true, false]) seems more natural to me. Because we first specify the function name, then we broadcast over it. .!([true, false]) seems like an exception to me. For example, .sin([0.5,0.5]) is not correct.

Dot-before is a special syntax for operators:


I guess most people prefer to save some typing so they use these, but (!). is perfectly fine too.
