# System
Module for system interactions.
This module defines the following items:
- The `sys.version` constant (of type [`version`]) that specifies
the currently active Typst compiler version.
- The `sys.inputs` [dictionary], which makes external inputs
available to the project. An input specified in the command line as
`--input key=value` becomes available under `sys.inputs.key` as
`{"value"}`. To include spaces in the value, it may be enclosed with
single or double quotes.
The value is always of type [string]($str). More complex data
may be parsed manually using functions like [`json.decode`]($json.decode).
