What you can do

• Edit scripts with syntax highlighting, folding, IntelliSense, find/replace, and built-in or custom snippets.
• Run PowerShell in independent tabs with persistent variables, functions, modules, and working directories.
• Explore commands through the Commands pane, command forms, and help.
• Debug scripts with breakpoints, stepping, variable inspection, watches, and a call stack.
• Work remotely through SSH or WSMan, including remote files and debugging.
• Extend the workbench with a supported $psISE scripting subset, per-tab Add-ons menus, and ISE snippet-management commands.
• Make it your own with themes, fonts, pane layouts, recovery copies, and keyboard navigation.

Getting started

Install a package

Download unsigned, self-contained packages from GitHub Releases, or from the Artifacts section of a successful Build and test Actions run.

Packages are not signed or notarized yet. Windows/macOS may warn or block launch according to local security policy. See installation and updates for file associations, manual updates, and verification limits.

Run from source

Install the .NET 10 SDK, then run from the repository root:

dotnet run --project src/Iseberg

To open a script at launch:

dotnet run --project src/Iseberg -- ./example.ps1

PowerShell is included through the SDK dependency; a separate pwsh installation is not required when running from source or using the full distribution.

Windows, Linux, and macOS are target platforms. Linux needs a graphical desktop and Avalonia's native dependencies. Native Linux/macOS desktop interaction has not yet been verified; see platform support for requirements and verification status.

The compact distribution is a smaller, single-executable alternative that requires a compatible PowerShell installation.

Your first script

1. Open a script with Ctrl+O, or create one with Ctrl+N.
2. Press F5 to run the script, or F8 to run a selection or the current line.
3. Use the console below the editor for commands and output. Each PowerShell tab keeps its own session.
4. Set a breakpoint with F9, then use F10 / F11 to step when execution pauses.

Scripts run with your account's permissions; Iseberg is not a sandbox. Windows execution policy is respected, and profiles are opt-in. See execution and profiles for blocked scripts and save-before-run behavior.

Keyboard shortcuts

On macOS, Command is also accepted for workbench shortcuts. See the full shortcut reference for layout, printing, and additional debugger actions.

Documentation

Development

Build and run the tests from the repository root:

dotnet build Iseberg.slnx
dotnet test Iseberg.slnx

The development guide covers test prerequisites, full and compact distributions, runtime checks, and VS Code launch configurations.
