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

## Install

From master branch  

`$ go install github.com/rafaelsq/wtc@latest`  

You can also install by release(linux64 only);  

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

Or just head to the [releases page](https://github.com/rafaelsq/wtc/releases) and download the latest version for you platform.

## Compile from source

Before you begin, ensure you have installed the latest version of Go. See the [Go documentation](https://golang.org/doc/install) for details.

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

## Usage

```

$ wtc --help

USAGE:

wtc [[flags] [regex command]]

        e.g.: wtc

            // will read [.]wtc.y[a]ml

        e.g.: wtc -r -sfmt "_test\.go$" "go test -cover {PKG}"

wtc [flags]] [rule-name]

        e.g.: wtc -t rule-name

             wtc --no-trace "rule ruleb"

             wtc -arg-pkg any/path rule

             wtc -arg-file path/to/file.ext rule

FLAGS:

  -arg-file string

        wtc -arg-file path/to/file rule-name

  -arg-pkg string

        wtc -arg-pkg path/to/folder rule-name

  -debounce int

        global debounce (default 300)

  -f string

        wtc config file (default try to find [.]wtc.y[a]ml)

  -ignore string

        regex

  -ignore-rules string

        ignore one or more rules (e.g.: -ignore-rules "ruleA,ruleB"

                                  or export WTC_IGNORE_RULES=ruleA,ruleB)

  -no-trace

        disable messages.

  -r    run on start

  -sfmt

        simple format(stderr red)

  -t string

        trig one or more rules by name

                e.g.: wtc -t ruleA

                     wtc -t "ruleA ruleB"

```

## Usage with [.]wtc.y[a]ml 

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

Example with all options:

```yaml

no_trace: false

debounce: 300  # if rule has no debounce, this will be used instead

ignore: \.git/

kill_signal: 2 # SIGINT (default: 9 SIGKILL)

kill_timeout: 3 # how many seconds we wait for the applicaton to exit before we send SIGKILL(9)

format:

  time: "15:04:05" # golang format

  ok: "\u001b[38;5;244m[{{.Time}}] \u001b[38;5;2m[{{.Title}}]\u001b[0m \u001b[38;5;238m{{.Message}}\u001b[0m\n"

  fail: "\u001b[38;5;244m[{{.Time}}] \u001b[38;5;1m[{{.Title}}] \u001b[38;5;238m{{.Message}}\u001b[0m\n"

  command_ok: "\u001b[38;5;240m[{{.Time}}] [{{.Title}}] \u001b[0m{{.Message}}\n"

  command_err: "\u001b[38;5;240m[{{.Time}}] [{{.Title}}] \u001b[38;5;1m{{.Message}}\u001b[0m\n"

trig: [start, buildNRun]  # will run start and after buildNRun

trig_async: # will run test and async concurrently

  - test

  - async

env:

  - name: PORT

    value: 2000

  - type: file

    name: ./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}

  - name: async

    command: echo async

```

Example base.env

```bash

export PORT=3000

# will be replaced by the environment variable

ENVIRONMENT=%{ENV}%

```

You can also trig a rule using `wtc -t`, example;  

`wtc -t "start buildNRun"`  

`wtc --no-trace buildNRun`  

## Dev

`$ make` will watch for changes and run `go install` or just run `$ go run main.go`

```yaml

debounce: 100

ignore: "\\.git/"

trig: install

rules:

  - name: install

    match: "\\.go$"

    command: "go install"

```
