To enhance your collaboration during code development and review, Box’s web app enables you to add code blocks to your Box Notes. In Box Notes, a code block contains a scrollable text field, a language selection field, and a selection to remove the code block. After adding a code block, you can either paste or type code into your code block’s text field. Code blocks in Box Notes support the following software languages:
  • Bash shell
  • C
  • C++
  • C#
  • CSS
  • Dart
  • Go
  • HTML
  • JavaScript
  • Perl
  • PHP
  • PowerShell
  • Python Java
  • R
  • Ruby
  • Rust
  • Scala
  • SQL
  • Swift
IMPORTANT:
  • After selecting a language for your code block, you cannot select a different language for that code block.
  • Box Notes does not support the use of code blocks on mobile devices.
As with all content in Box Notes, multiple people can simultaneously edit a code block’s contents.
When someone is working in your code block’s contents, Box displays a collaboration icon in the code block’s text field identifying the person’s user name.
Collaborators with Read-only permission can view but not edit a code block’s contents.
Note:  Box Notes does not support the insertion of other Box Note elements — for example, tables, images, call-out boxes, headings, or other code blocks — into code blocks.  To learn more about using other Box Notes elements, start here.
