waiter

Waiter is an abstract development server for compiled languages. It runs your server, compiles it when you change a file, and manages compilation and server processes.

Install

Homebrew

$ brew tap davejachimiak/tap
$ brew install waiter

Usage

$ waiter SERVER_COMMAND BUILD_COMMAND [-f|--file-name-regex REGEX] [-d|--dir DIR]

Example:

$ waiter "ENV=development ./blog-server" "cabal build" -f "hs$" -d ./lib

That would run your server binary ./blog-server with the environment variable ENV set to development. It would run cabal build when files with the regex hs$ in the ./lib tree change. After all build processes finish, it would kill the previous ./blog-server process and start a new one from the newly built binary.

Required:

SERVER_COMMAND

This is the command that runs your server.

Example:

"ENV=developemnt ./blog-server"

BUILD_COMMAND

This is the command that builds your server. It should generate the binary run by SERVER_COMMAND.

Example:

"cabal build"

Optional

[-f|--file-name-regex REGEX]

Only filenames matching this regex trigger BUILD_COMMANDs. Uses POSIX regular expression interface. Defaults to .*.

[-d|--dir DIR]

Only changes to files in this directory's tree trigger BUILD_COMMANDs. Defaults to ./src.
