WTC

WTC is a simple utility you can use to watch files and execute commands.

Install

Latest Release
$ curl -sfL --silent https://github.com/rafaelsq/wtc/releases/latest/download/wtc.linux64.tar.gz | tar -xzv && mv wtc $(go env GOPATH)/bin/

Compile from source

Before you begin, ensure you have installed the latest version of Go. See the Go documentation for details.

$ go get -u github.com/rafaelsq/wtc

Usage

$ wtc [[flags] [regex command]]

FLAGS:
  -debounce int
        global debounce (default 300)
  -f string
        wtc config file (default try to find [.]wtc.y[a]ml)
  -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/
format:
  ok: "{{.Time}} \u001b[38;5;2m[{{.Name}}]\u001b[0m - {{.Command}}\n"
  fail: "{{.Time}} \u001b[38;5;1m[{{.Name}}]\u001b[0m - {{.Error}}\n"
trig: [start, buildNRun]  # will run on start
env:
  - name: PORT
    value: 2000
  - name: BASE_FILE
    value: ./base.env
rules:
  - name: start
  - name: buildNRun
    match: \.go$
    ignore: _test\.go$
    command: go build
    env:
      - name: ENV
        value: development
      - name: %{BASE_FILE}% # replace from environment
        type: file
    trig: 
      - done build
      - run
      - test
  - name: done build
  - name: run
    command: ./$(basename `pwd`)
  - name: test
    env:
      - name: ENV
        value: test
      - name: %{BASE_FILE}%
        type: file
    match: _test\.go$
    command: go test -cover {PKG}

Example base.env

export PORT=3000

# replace from environment
ENVIRONMENT=%{ENV}%

Dev

$ make will watch for changes and run go install

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