What this is:

• Go file watcher, builder, and runner.
• Barebones (fast), cross-platform (uses fsnotify), recursive, and configurable.
• Organized architecture, as an experimental project for practicing Go.

To install:

go get github.com/rw3iss/gow

Or from source:

git clone https://github.com/rw3iss/gow.git
cd gow
go install

To use:

gow

Will watch all files in the current directory, recursively, and run 'go build' when there is any change.

File structure / explanation:

main.go                 - Entry point, runs initial build and starts watcher.
lib/                    - (Underlying application library)
    Application.go      - Wrapping context for entire Application.
    Builder.go          - Manages process of running build command.
    Runner.go           - Manages process of running actual target executable. 
    Watcher.go          - Manages process of watching files, and restart routine.
    utils/              - (Library utilites)
        Colors.go       - Color definitions.
        Config.go       - Helper to read in configuration file.
        FormatWriter.go - Generic Writer, accepts format string and prints output.
        Log.go          - Helper to print outputs.
test/                   - (Test package, run 'gow' here and it will run test.go)
    test.go             - Simple test program to print/test automatic changes.

Todo

• implement Config to specify a regex of file extensions to react to.
