Xtext semantics file
File type: Source code and script file
A .seman file is an Xtext semantics source file. It contains semantic definitions for a programming language or domain-specific language developed with Xtext.
The file belongs to an Xtext language project and is intended to be processed as source code rather than opened as a standalone document.

Xtext is an Eclipse project and framework for developing programming languages and domain-specific languages. A .seman file stores semantic information used by an Xtext-based language project.
The file is part of the project's source files and is interpreted together with the other project resources by the Xtext development tools. Its contents are specific to the language project that created it.
Xtext tooling is available on multiple platforms. The .seman format is a source format for Xtext projects, not a general-purpose data or document format.
Open the .seman file in the Xtext development environment, typically as part of the project that contains it. An Xtext-enabled Eclipse installation can provide project-specific validation and other language tooling.
If the associated project is unavailable, the file can be viewed as text in a source-code editor, but its Xtext-specific semantics may not be available.
There is no standard standalone conversion for an .seman file. Its contents are source files for an Xtext language project and normally remain in that project.
To change the language implementation, edit the file in Xtext and use the project's configured build or generation process. Any conversion to another language or format requires a project-specific rewrite or transformation.
