waf / CSharpRepl

C# REPL is a tool for rapid experimentation and exploration of C# expressions, statements, and NuGet packages. It provides a command line REPL for C# that supports syntax highlighting, intellisense, and type/method documentation.

This C# REPL helps you explore the C# language and libraries, including the .NET SDK and NuGet packages. It's also useful for iteratively defining and refining functions when developing software.

Run csharprepl from the command line to begin an interactive session. The default colorscheme uses the color palette defined by your terminal, but these colors can be changed using a theme.json file provided as a command line argument.

Additionally, if the statement is not a "complete statement" a newline will automatically be inserted when Enter is pressed. For example, in the below code, the first line is not a syntactically complete statement, so when we press enter we'll go down to a new line:

Finally, pressing Ctrl+Enter will show a "detailed view" of the result. For example, for the DateTime.Now expression below, on the first line we pressed Enter, and on the second line we pressed Ctrl+Enter to view more detailed output:
