t4 命令

常用示例

说明

t4 is a command-line tool for processing T4 (Text Template Transformation Toolkit) templates, a general-purpose way to use C# to generate any kind of text or code files. It is part of Mono.TextTemplating, a modern open-source reimplementation of the Visual Studio T4 text templating engine. The tool operates in two modes: direct template processing, which generates output files immediately, and preprocessing, which converts templates into runtime template classes that can be embedded in applications and executed at runtime. Templates use C# code blocks delimited by <# and #> tags to emit dynamic content. Parameter directives support automatic type conversion from CLI string values to the type specified in the template. The tool can read templates from standard input and write output to standard output, enabling pipeline integration.
