PowerShell language support in Atom
This package provides PowerShell language support in the Atom editor by leveraging the PowerShell syntax from Microsoft.
If you discover any issues with the way the syntax is highlighted, please open an issue against the PowerShell/EditorSyntax repository instead of this one, since this package is based on that grammar.
Any issues that aren’t related to the grammar are fair game here, though! Start one here.
