Usage

USAGE:
$ wtc [[flags] regex command]

If [.]wtc.yaml exists, it will be used.

FLAGS:
  -debounce int
    	global debounce (default 300)
  -ignore string
    	regex
  -no-trace
    	disable messages.

Example

wtc "_test\.go$" "go test -cover {PKG}"

Usage with [.]wtc.yaml

You can configure WTC by creating an YAML file with your own rules.

Example:

no_trace: false
debounce: 300  # if rule has no debounce, this will be used instead
ignore: "\\.git/"
trig: buildNRun  # will run on start
rules:
  - name: buildNRun
    match: "\\.go$"
    ignore: "_test\\.go$"
    command: "go build"
    trig: run
  - name: run
    command: "./$(basename `pwd`)"
  - name: test
    match: "_test\\.go$"
    command: "go test -cover {PKG}"

Dev

$ make will watch for changes and run go install

debounce: 100
ignore: "\\.git/"
trig: install
rules:
  - name: install
    match: "\\.go$"
    command: "go install"
