Answer Set Programming Language Support (for Clingo)

| Potassco | Potassco on Github | Clingo | Get it on Open VSX Registry

This Extension uses Clingo Answer Set Solver (bundled), developed by Potassco (University of Potsdam). We added multi-file support with v0.4.0!

Usage

Just right click anywhere on a logic program (.lp) file and select Compute all Answer Sets, Compute the first Answer Set or Compute Answer Sets (config.json). This will display Clingo's results in a seperate ASP tab located in the panel. You can also use the buttons in the top right of this tab to run bundled or PATH clingo depending on your ASPLanguage: Use PATH Clingo setting.

If you want to add additional startup arguments you can use the Compute Answer Sets (config.json) option. For this, you can generate a sample config.json file with the ASPLanguage: Initialize clingo config file in current working directory command (Press Ctrl+Shift+P).

This will create a config file with all supported arguments/settings in your current working directory. If you want to use your own config file, just change the config file name in the extension settings (ASPLanguage: Set Config). Additionally you can use arguments not directly supported by the config.json by passing them in the "customArgs" setting as a string.

If you need to work with multiple files specify them in additional files in this config file using the relative path from the current working directory. See the Clingo Documentation (PDF) for more details on the config settings!

If you want to use your own Version of Clingo from PATH with this extension, please enable ASPLanguage: Use PATH Clingo option in your settings.

Customization

When using the bundled WASM Clingo (Choose in configuration ASPLanguage: Use PATH Clingo), you can easily move the panel to the sidebars or change the panel position depending on your preferences. The layout will adjust accordingly!

Requirements

For the extension to work properly, please install the Answer Set Programming syntax highlighter by abelcour (abelcour.asp-syntax-highlight) Answer Set Syntax Highlighter
