`peace` is a framework to build user friendly software automation.

See:

* [peace.mk](https://peace.mk) for the project vision.
* [Background](https://peace.mk/book/background.html) for the motivation to create this framework.
* [Operations UX](https://azriel.im/ops_ux/) for a book about the dimensions considered during `peace`'s design and development.


## Guiding Principles

* A joy to use.
* Ergonomic API and guidance to do the right thing.
* Understandable output.


## Features

| Symbol | Meaning              |
|:------:|:---------------------|
|   🟢   | Works well           |
|   🟡   | Partial support      |
|   ⚫   | Planned              |
|   🔵   | Compatible by design |
|   🟣   | Works, "fun idea"    |

* 🟢 Define items to manage with automation
* 🟢 Define dependencies between items
* 🟢 Discover current and desired states
* 🟢 Show diff: what would change
* 🟢 Store and recall parameters across commands
* 🟢 Concurrent task execution via [`fn_graph`]
* 🟢 Skip unnecessary work
* 🟢 Idempotence: Multiple executions
* 🟢 Show state differences
* 🟢 Namespaced profile directories
* 🟢 Resource clean up
* 🟢 Understandable progress
* 🟡 Feature-gated incremental functionality
* 🟡 Off-the-shelf support for common items
* 🟡 Dry run
* 🔵 Understandable error reporting via [`miette`]
* 🔵 Actionable error messages
* 🟣 WASM support
* ⚫ Tutorial for writing a software lifecycle management tool
* ⚫ Built-in application execution methods -- CLI, web service
* ⚫ `peace` binary for configuration based workflows
* ⚫ Web based UI
* ⚫ Agent mode to run `peace` on servers (Web API invocation)

Further ideas:

* Back up current state
* Restore previous state
* Telemetry logging for monitoring
* Metrics collection for analysis


## Examples

Examples are run using `--package` instead of `--example`, as each example is organized as its own crate.

```bash
cargo run --package $example_name --all-features

# e.g.
cargo build --package download --all-features
cargo run -q --package download --all-features -- init https://ifconfig.me ip.json

for cmd in status desired diff ensure diff clean diff
do
    printf "=== ${cmd} ===\n"
    cargo run -q --package download --all-features -- $cmd
    printf '\n'
done

# Look at metadata that Peace has saved
find .peace -type f -exec bash -c 'echo \# {}; cat {}; echo' \;

# Clean up the metadata directory
rm -rf .peace
```

### WASM

The `download` example can be built as a web assembly application using [`wasm-pack`]:

```bash
cd examples/download
wasm-pack build --target web
```

In the `examples/download` directory, start an [HTTP server], and open <http://localhost:8000/>:

```bash
python3 -m http.server 8000 # or
simple-http-server --nocache --port 8000 -i
```
