# Stand with Ukraine!
---
While Russia is destroying my home and my country, killing my friends and neighbors - any russian company, organization, or citizen, who do nothing about it,
is prohibited from using this package.
For others - please, pray for us, share information about war crimes Russia is conducting in Ukraine, do everything you can
to urge your governments to be on the right side of history.
Ukraine will prevail! Good triumph over evil! Русский военный корабль, иди нах#й!

Simple modern alternative to GNU Make. *taskctl* is concurrent task runner that allows you to design you routine tasks and development pipelines in nice and neat way in human-readable format (YAML, JSON or TOML).
Given a pipeline (composed of tasks or other pipelines) it builds a graph that outlines the execution plan. Each task my run concurrently or cascade.
Beside pipelines, each single task can be started manually or triggered by built-in filesystem watcher.
## Features
- human-readable configuration format (YAML, JSON or TOML)
- concurrent tasks execution
- highly customizable execution plan
- cross platform
- import local or remote configurations
- integrated file watcher (live reload)
- customizable execution contexts
- different output types
- embeddable task runner
- interactive prompt
- handy autocomplete
- and many more...
```yaml
tasks:
lint:
command:
- golint $(go list ./... | grep -v /vendor/)
- go vet $(go list ./... | grep -v /vendor/)
test:
allow_failure: true
command: go test ./....
build:
command: go build -o bin/app ./...
env:
GOOS: linux
GOARCH: amd64
before: rm -rf bin/*
pipelines:
release:
- task: lint
- task: test
- task: build
depends_on: [lint, test]
```
According to this plan `lint` and `test` will run concurrently, `build` will start only when both `lint` and `test` finished.

### Usage
- `taskctl` - run interactive task prompt
- `taskctl pipeline1` - run single pipeline
- `taskctl task1` - run single task
- `taskctl pipeline1 task1` - run one or more pipelines and/or tasks
- `taskctl watch watcher1 watcher2` - start one or more watchers
## Configuration
*taskctl* uses config file (`tasks.yaml` or `taskctl.yaml`) where your tasks and pipelines stored.
Config file includes following sections:
- tasks
- pipelines
- watchers
- contexts
- variables
Config file may import other config files, directories or URLs.
```yaml
import:
- .tasks/database.yaml
- .tasks/lint/
- https://raw.githubusercontent.com/taskctl/taskctl/master/docs/example.yaml
```
### Example
Config file [example](https://github.com/taskctl/taskctl/blob/master/docs/example.yaml)
### Global configuration
*taskctl* has global configuration stored in ``$HOME/.taskctl/config.yaml`` file. It is handy to store system-wide tasks, reusable contexts, defaults etc.
## Tasks
Task is a foundation of *taskctl*. It describes one or more commands to run, their environment, executors and attributes such as working directory, execution timeout, acceptance of failure, etc.
```yaml
tasks:
lint:
allow_failure: true
command:
- golint $(go list ./... | grep -v /vendor/)
- go vet $(go list ./... | grep -v /vendor/)
build:
command: go build ./...
env:
GOOS: linux
GOARCH: amd64
env_file: /data/.env
after: rm -rf tmp/*
variations:
- GOARCH: amd64
- GOARCH: arm
GOARM: 7
```
Task definition takes following parameters:
- `command` - one or more commands to run
- `variations` - list of variations (env variables) to apply to command
- `context` - execution context's name
- `env` - environment variables. All existing environment variables will be passed automatically
- `env_file` - env file in `k=v` format to read variables from
- `dir` - working directory. Current working directory by default
- `timeout` - command execution timeout (default: none)
- `allow_failure` - if set to `true` failed commands will not interrupt execution (default: `false`)
- `after` - command that will be executed after command completes
- `before` - command that will be executed before task starts
- `exportAs` - env variable name to store task's output (default: `TASK_NAME_OUTPUT`, where `TASK_NAME` is actual task's name)
- `condition` - condition to check before running task
- `variables` - task's variables
- `interactive` - if `true` provides STDIN to commands (default: `false`)
### Tasks variables
Each task, stage and context has variables to be used to render task's fields - `command`, `dir`.
Along with globally predefined, variables can be set in a task's definition.
You can use those variables according to `text/template` [documentation](https://golang.org/pkg/text/template/).
Predefined variables are:
- `.Root` - root config file directory
- `.Dir` - config file directory
- `.TempDir` - system's temporary directory
- `.Args` - provided arguments as a string
- `.ArgsList` - array of provided arguments
- `.Task.Name` - current task's name
- `.Context.Name` - current task's execution context's name
- `.Stage.Name` - current stage's name
- `.Output` - previous command's output
- `.Tasks.Task1.Output` - `task1` last command output
Variables can be used inside task definition. For example:
```yaml
tasks:
task1:
dir: "{{ .Root }}/some-dir"
command:
- echo "My name is {{ .Task.Name }}"
- echo {{ .Output }} # My name is task1
- echo "Sleep for {{ .sleep }} seconds"
- sleep {{ .sleep | default 10 }}
- sleep {{ .sleep }}
variables:
sleep: 3
```
### Pass CLI arguments to task
Any command line arguments succeeding `--` are passed to each task via `.Args`, `.ArgsList` variables or `ARGS` environment variable.
Given this definition:
```yaml
lint1:
command: go lint {{.Args}}
lint2:
command: go lint {{index .ArgsList 1}}
```
the resulting command is:
```
$ taskctl lint1 -- package.go
# go lint package.go
$ taskctl lint2 -- package.go main.go
# go lint main.go
```
### Storing task's output
Task output automatically stored to the variable named like this - ``.Tasks.TaskName.Output``, where `TaskName` is the actual task's name.
It is also stored to `TASK_NAME_OUTPUT` environment variable. It's name can be changed by a task's `exportAs` parameter.
Those variables will be available to all dependent stages.
### Tasks variations
Task may run in one or more variations. Variations allows to reuse task with different env variables:
```yaml
tasks:
build:
command:
- GOOS=${GOOS} GOARCH=amd64 go build -o bin/taskctl_${GOOS} ./cmd/taskctl
env:
GOFLAGS: -ldflags=-s -ldflags=-w
variations:
- GOOS: linux
- GOOS: darwin
- GOOS: windows
```
this config will run build 3 times with different GOOS
### Task conditional execution
The following task will run only when there are any changes that are staged but not committed:
```yaml
tasks:
build:
command:
- ...build...
condition: git diff --exit-code
```
## Pipelines
Pipeline is a set of stages (tasks or other pipelines) to be executed in a certain order. Stages may be executed in parallel or one-by-one.
Stage may override task's environment, variables etc.
This pipeline:
```yaml
pipelines:
pipeline1:
- task: start task
- task: task A
depends_on: "start task"
- task: task B
depends_on: "start task"
- task: task C
depends_on: "start task"
- task: task D
depends_on: "task C"
- task: task E
depends_on: ["task A", "task B", "task D"]
- task: finish
depends_on: ["task E"]
```
will result in an execution plan like this:
Stage definition takes following parameters:
- `name` - stage name. If not set - referenced task or pipeline name will be used.
- `task` - task to execute on this stage
- `pipeline` - pipeline to execute on this stage
- `env` - environment variables. All existing environment variables will be passed automatically
- `depends_on` - name of stage on which this stage depends on. This stage will be started only after referenced stage is completed.
- `allow_failure` - if `true` failing stage will not interrupt pipeline execution. ``false`` by default
- `condition` - condition to check before running stage
- `variables` - stage's variables
## Taskctl output formats
Taskctl has several output formats:
- `raw` - prints raw commands output
- `prefixed` - strips ANSI escape sequences where possible, prefixes command output with task's name
- `cockpit` - tasks dashboard
## Filesystem watchers
Watcher watches for changes in files selected by provided patterns and triggers task anytime an event has occurred.
```yaml
watchers:
watcher1:
watch: ["README.*", "pkg/**/*.go"] # Files to watch
exclude: ["pkg/excluded.go", "pkg/excluded-dir/*"] # Exclude patterns
events: [create, write, remove, rename, chmod] # Filesystem events to listen to
task: task1 # Task to run when event occurs
```
### Patterns
Thanks to [doublestar](https://github.com/bmatcuk/doublestar) *taskctl* supports the following special terms within include and exclude patterns:
Special Terms | Meaning
------------- | -------
`*` | matches any sequence of non-path-separators
`**` | matches any sequence of characters, including path separators
`?` | matches any single non-path-separator character
`[class]` | matches any single non-path-separator character against a class of characters ([details](https://github.com/bmatcuk/doublestar/blob/master/README.md#character-classes))
`{alt1,...}` | matches a sequence of characters if one of the comma-separated alternatives matches
Any character with a special meaning can be escaped with a backslash (`\`).
## Contexts
Contexts allow you to set up execution environment, variables, binary which will run your task, up/down commands etc.
```yaml
contexts:
local:
executable:
bin: /bin/zsh
args:
- -c
env:
VAR_NAME: VAR_VALUE
variables:
sleep: 10
quote: "'" # will quote command with provided symbol: "/bin/zsh -c 'echo 1'"
before: echo "I'm local context!"
after: echo "Have a nice day!"
```
Context has hooks which may be triggered once before first context usage or every time before task with this context will run.
```yaml
context:
docker-compose:
executable:
bin: docker-compose
args: ["exec", "api"]
up: docker-compose up -d api
down: docker-compose down api
local:
after: rm -rf var/*
```
### Docker context
```yaml
alpine:
executable:
bin: /usr/local/bin/docker
args:
- run
- --rm
- alpine:latest
env:
DOCKER_HOST: "tcp://0.0.0.0:2375"
before: echo "SOME COMMAND TO RUN BEFORE TASK"
after: echo "SOME COMMAND TO RUN WHEN TASK FINISHED SUCCESSFULLY"
tasks:
mysql-task:
context: alpine
command: uname -a
```
## Embeddable task runner
*taskctl* may be embedded into any go program.
Additional information may be found on taskctl's [pkg.go.dev](https://pkg.go.dev/github.com/taskctl/taskctl?tab=overview) page
### Runner
```go
t := task.FromCommands("go fmt ./...", "go build ./..")
r, err := NewTaskRunner()
if err != nil {
return
}
err = r.Run(t)
if err != nil {
fmt.Println(err, t.ExitCode, t.ErrorMessage())
}
fmt.Println(t.Output())
```
### Scheduler
```go
format := task.FromCommands("go fmt ./...")
build := task.FromCommands("go build ./..")
r, _ := runner.NewTaskRunner()
s := NewScheduler(r)
graph, err := NewExecutionGraph(
&Stage{Name: "format", Task: format},
&Stage{Name: "build", Task: build, DependsOn: []string{"format"}},
)
if err != nil {
return
}
err = s.Schedule(graph)
if err != nil {
fmt.Println(err)
}
```
## FAQ
### How does it differ from go-task/task?
It's amazing how solving same problems lead to same solutions. *taskctl* and go-task have a lot of concepts in common but also have some differences.
1. Main is pipelines. Pipelines and stages allows more precise workflow design because same tasks may have different dependencies (or no dependencies) in different scenarios.
2. Contexts allow you to set up execution environment and binary which will run your task.
