Introduction • Getting Started • Contributing • Roadmap
Fn is a "function-oriented" general purpose automation tool that aims to be simpler and more flexible than similar tools such as Make, Task, and Rake.
Fn aims to have a human-centered design, with emphasis on usability and aesthetics.
Even the smartest among us can feel inept as we fail to figure out which light switch or oven burner to turn on, or whether to push, pull, or slide a door. The fault lies not in ourselves, but in product design that ignores the needs of users and the principles of cognitive psychology.
The problems range from ambiguous and hidden controls to arbitrary relationships between controls and functions, coupled with a lack of feedback or other assistance and unreasonable demands on memorization.
The rules are simple: make things visible, exploit natural relationships that couple function and control, and make intelligent use of constraints.
The goal: guide the user effortlessly to the right action on the right control at the right time.
An example to get you started:
fnfile.yml
version: '0.1'
fns:
hello: echo "Hello, World!"❯ fn hello
Hello, Worldgo install github.com/go-fn/fn| Feature | Explanation |
|---|---|
ui |
An interactive UI that makes running fn easy, fun, and informative |
cli |
POSIX compliant cli for use with automation |
templating |
Leverage Go Templates as an alternative to shell commands |
include |
Include content from local or remote fnfile.yml files. |
outputs |
Tired of reading walls of log output? Fn supports a wide range of options for how output is presented, so you can find what you need, and move on. |
watch |
Integration with viddy to watch a fn |
fwatch |
Integration with fsnotify to provide "rerun" functionality when files change |
src/gen |
Fingerprint files between runs, useful to skip expensive steps |
| Keyword | Description |
|---|---|
fn |
A series of steps (aka function) |
step |
An abstract behavior |
sh |
A step that runs a shell command |
do |
A step that runs other steps in sequence |
parallel |
A step that runs other steps in parallel |
defer |
A step that is run when the surround fn completes (success or failure) |
matrix |
Dynamically defined steps |
return |
A step that triggers the parent step to end early (such as when part of a do) |
var |
A lazily evaluated (then optionally memoized/cached) value |
ctx |
A collection of values that are available at different points in an fnfile |
ns |
A namespace for fn's |
serialgroup |
Control concurrency of step's or fn's through labelling |
