Files
River files are plaintext files with the .river
file extension. Each River
file may be referred to as a “configuration file,” or a “River configuration.”
River files are required to be UTF-8 encoded, and are permitted to contain Unicode characters. River files can use both Unix-style line endings (LF) and Windows-style line endings (CRLF), but formatters may replace all line endings with Unix-style ones.
Community tooling
There is experimental support for River in vim and in VSCode.
