Boo is an object-oriented, statically typed programming language for the Common Language Infrastructure (CLI). It uses Python-inspired syntax and supports compiler and language extensibility.
A .boo file is a text-based source file used to write Boo programs and classes. Multiple Boo source files can be combined as part of a project before compilation.
The Boo compiler processes these files into assemblies for the .NET or compatible CLI runtime. The format is associated with Boo development tools on Microsoft Windows, although the resulting CLI code is intended for the wider .NET ecosystem.
On Windows, open a .boo file with the Boo compiler or a Boo development environment to build the source code. A plain-text editor can be used to inspect or edit the file, because Boo source is text-based.
Opening the file in a general editor does not run the program; it only displays its source code.
The Boo compiler can compile the source into a .NET or CLI assembly, such as an executable or library, but this is a build operation rather than a file-format conversion.
Converting Boo source to another programming language generally requires a manual rewrite.
