# IC SDK
This repo contains the `IC SDK`: a Software Development Kit for creating and managing [canister smart contracts on the Internet Computer (ICP blockchain)](https://wiki.internetcomputer.org/wiki/Canister_smart_contract).

## What gets installed
The `IC SDK` installation script installs several components in default locations on your local computer. The following table describes the development environment components that the installation script installs:
| Component | Description | Default location |
|--------------|----------------------------------------------------------------------------------------------------|-----------------------------------------------|
| dfx | Command-line interface (CLI) | `/usr/local/bin/dfx` |
| moc | Motoko runtime compiler | `~/.cache/dfinity/versions//moc` |
| replica | Internet Computer local network binary | `~/.cache/dfinity/versions//replica` |
| uninstall.sh | Script to remove the SDK and all of its components | `~/.cache/dfinity/uninstall.sh` |
| versions | Cache directory that contains a subdirectory for each version of the SDK you install. | `~/.cache/dfinity/versions` |
## SDK vs CDK vs `dfx`
There are a few components above worth expanding on:
1. **dfx** - `dfx` is the command-line interface for the `IC SDK`. This is why many commands for the IC SDK start with the command "`dfx ..`" such as `dfx new` or `dfx stop`.
2. **Canister Development Kit (CDK)** - A CDK is an adapter used by the IC SDK so a programming language has the features needed to create and manage canisters.
The IC SDK comes with a few CDKs already installed for you so you can use them in the language of yoru choice. That is why there is a [Rust CDK](https://github.com/dfinity/cdk-rs), [Python CDK](https://demergent-labs.github.io/kybra/),
[TypeScript CDK](https://demergent-labs.github.io/azle/), etc... Since CDKs are components used the SDK, some developer choose to use the CDK directly (without the `IC SDK`),
but typically are used as part of the whole `IC SDK`.
## Getting Started
### Installing
You can install the `IC SDK` a few different ways.
#### via `curl` (recommended)
``` bash
sh -ci "$(curl -fsSL https://internetcomputer.org/install.sh)"
```
This command will install a binary compatible with your operating system, and add it to `/usr/local/bin`.
#### via GitHub Releases
Find a release for your architecture [here](https://github.com/dfinity/sdk/releases).
#### in GitHub Action, using [`dfinity/setup-dfx`](https://github.com/dfinity/setup-dfx)
```yml
steps:
- name: Install dfx
uses: dfinity/setup-dfx@main
```
### Getting Help
Once the `IC SDK` is installed, get acquainted with its capabilities by entering.
``` bash
dfx help
```

### Building the IC SDK
Building the `IC SDK` is very simple:
``` bash
cargo build
```
## Release Process
`IC SDK` is released in two steps:
1. Publishing a new `IC SDK` release.
2. Publishing a new `manifest.json` and `install.sh` to instruct the installer
to actually download and install the new `IC SDK` release.
### Publishing the IC SDK
1. The release manager makes sure the `dfx` `stable` branch points to the revision
that should be released and that the revision is tagged with a version (like
`0.5.6`).
2. The
[`sdk-release`](https://hydra.dfinity.systems/jobset/dfinity-ci-build/sdk-release#tabs-configuration)
jobset on Hydra tracks the `stable` branch and starts evaluating shortly
after `stable` advances.
3. As you can see it only has the single job `publish.dfx` which is
defined [here](https://github.com/dfinity-lab/sdk/blob/stable/ci/release.nix)
in terms of the
[`dfx`](https://github.com/dfinity-lab/sdk/blob/stable/publish.nix) job. Note
that the `publish.dfx` job only exists when the revision has a
proper version tag. This prevents publishing of untagged revisions.
4. Our CD system running at `deployer.dfinity.systems` is configured with the
[`publish-sdk-dfx-release`](https://github.com/dfinity-lab/infra/blob/1fe63e06135be206d064a74461f739c4fafec3c7/services/nix/publish-sdk-release.nix#L39:L47)
job. It will monitor the aforementioned `publish.dfx` job for
new builds, whenever there's a new build it will download the output (the CD
script) and execute it.
5. As you can see the script also sends a message to the `#build-notifications`
Slack channel so you can see when and if the SDK has been published.
### Publishing `manifest.json` and `install.sh`
After the `IC SDK` has been released it's available for download but the install
script at https://sdk.dfinity.org/install.sh won't immediately install it. To
make sure the installer actually downloads and installs the new `IC SDK` release the
`manifest.json` file at https://sdk.dfinity.org/manifest.json has to set its
`tags.latest` field to the new version. The following explains how to do that.
1. Edit the `public/manifest.json` file such that it points to the new `IC SDK`
version and make sure this is merged in `master`.
2. Similarly to releasing the `IC SDK` there's a
[`install-sh`](https://github.com/dfinity-lab/sdk/blob/stable/publish.nix) job
that builds a CD script for publishing the `manifest.json` and `install.sh`
to our CDN.
3. This
[job](https://hydra.dfinity.systems/job/dfinity-ci-build/sdk/publish.install-sh.x86_64-linux)
is built on the `sdk` jobset which tracks the `master` branch.
4. `deployer.dfinity.systems` is configured with the
[`publish-sdk-install-sh`](https://github.com/dfinity-lab/infra/blob/1fe63e06135be206d064a74461f739c4fafec3c7/services/nix/publish-sdk-release.nix#L48:L56)
job which will monitor the aforementioned `publish.install-sh.x86_64-linux`
job for new builds, whenever there's a new build it will download the output
(the CD script) and execute it.
## Troubleshooting
This section provides solutions to problems you might encounter when using the `IC SDK` via `dfx` command line
### Project Reset
This command will remove the build directory and restart your replica:
``` bash
dfx stop && dfx start --clean --background
```
### Using Internet Identity Locally
You can deploy the Internet Identity canister into your replica alongside your project by cloning https://github.com/dfinity/internet-identity. From the `internet-identity` directory, run the following command:
``` bash
II_ENV=development dfx deploy --no-wallet --argument '(null)'
```
