OmniScript Format (OSF) is a universal document DSL that lets you write structured content once and export to multiple formats:

@meta { title: "Sales Report"; date: "2025-10-16"; }
@doc {
# Q4 Sales Report
**Outstanding performance** across all regions!
}
@table {
caption: "Regional Performance";
style: "bordered";
alignment: ["left", "right", "center"];
| Region | Revenue | Status |
| --- | --- | --- |
| North | $120K | ✓ Growth |
| South | $95K | → Stable |
| East | $145K | ✓ Growth |
}
@chart {
type: "bar";
title: "Revenue by Region";
data: [
{ label: "North"; values: [120]; },
{ label: "South"; values: [95]; },
{ label: "East"; values: [145]; }
];
}
@include { path: "./sections/recommendations.osf"; }
