OpenFAST, ROSCO & TurbSim Syntax Highlighting
Unofficial VS Code extension for OpenFAST, ROSCO, and TurbSim input and output files.
Features
- Syntax highlighting for OpenFAST-style text input files such as
.fst, .dat, .in, .inp, .out, .ipt, .ech, .wnd, .sum, and .bmi
- Support for common OpenFAST module files including AeroDyn, ElastoDyn, HydroDyn, InflowWind, MoorDyn, ServoDyn, SeaState, and related driver files
- Support for ROSCO-style
DISCON.in controller files
- Support for TurbSim input files (
.inp, and .in)
- Highlighting for:
- section banners and
END markers
- booleans and special values like
default, unused, and none
- quoted strings and file paths
- integers, decimals, and scientific notation
- parameter names in the common
value parameter - description layout
! comments and trailing inline descriptions
Installation
From the VS Code Marketplace (recommended):
- Open VS Code.
- Go to the Extensions view (
Ctrl+Shift+X).
- Search for OpenFAST ROSCO Syntax Highlighting.
- Click Install.
From a .vsix file:
- Download the
.vsix file from the Releases page.
- Open VS Code and go to the Extensions view (
Ctrl+Shift+X).
- Click the
... menu at the top right and select Install from VSIX....
- Select the downloaded file.
Once installed, any file with a supported extension (.fst, .dat, .in, .inp, etc.) will be highlighted automatically.
Scope
The grammar is built from real OpenFAST, ROSCO, and TurbSim sample files, not from a generic INI or config grammar.
It is designed to make engineering input decks easier to read without trying to fully parse every module format.

Notes
- Because
.dat and .in are generic extensions, this extension may also match non-OpenFAST files if enabled globally.
- ROSCO YAML files are intentionally not claimed by this extension because standard YAML support in VS Code is usually the better default.
