# `lens`
## Inactive :
This repository is now inactive. It will be kept open (non-archived) but will no longer be actively developed by Strangelove.
**Lens provides a command line tool to interact with any cosmos chain supporting the core [Cosmos-SDK modules](https://github.com/cosmos/cosmos-sdk/tree/master/x).**
**Lens is meant to be imported as a library in other repos and projects to easily navigate and interact with the Cosmos Hub along with IBC chains.**
---
`lens` is your lens to view the Cosmos :atom:. `lens` packs all the best practices in golang cosmos client development into one place and provides a simple and easy to use APIs provided by standard Cosmos chains. The `cmd` package implements the `lens` command line tool while the `client` package contains all the building blocks to build your own, complex, feature rich, Cosmos client in go.
Intended use cases:
- Trading Bots
- Server side query integrations for alerting or other automation
- Indexers and search engines
- Transaction automation (`x/authz` for security) for farming applications
- ...:atom::rocket::moon:
This is the start of ideas around how to implement the cosmos client libraries in a seperate repo.
## **--INSTALL--**
---
```bash
git clone https://github.com/strangelove-ventures/lens.git
cd lens
make install
```
Now run:
```bash
lens
```
You should see:
```
❯ lens
This is my lens, there are many like it, but this one is mine.
Usage:
lens [command]
Available Commands:
chains manage local chain configurations
keys manage keys held by the relayer for each chain
query query things about a chain
tendermint all tendermint query commands
tx query things about a chain
help Help about any command
Flags:
--chain string override default chain
-d, --debug debug output
-h, --help help for lens
--home string set home directory (default "/Users/lenscrafters/.lens")
Use "lens [command] --help" for more information about a command.
```
## **--CONFIG--**
---
The config file describes how lens will interact with blockchains. This is where information such as grpc addresses and chain-ids are held.
**Config File Location:** `~/.lens/config.yaml`
> NOTE: The config file is not created at install, it is created the first time lens needs to query your config. Just to get it created, you can run something like:
>```
>lens chains show-default
>```
### **CHAINS**
Lens comes with two default chains. Cosmos Hub and Osmosis.
To interact with other chains, you need to add them to your config. To do this, run:
```
lens chains add
#Example:
lens chains add juno
```
To view all possible chain names, run:
```
lens chains registry-list
```
> NOTE: These two commands check the chain registry located [here](https://github.com/cosmos/chain-registry), for the requested chain.
When running a command, it will run the command for the defaulted chain.
To view your default chain, run:
```
lens chains show-default
```
To change your default, run:
```
lens chains set-default
```
### **Keys**
Lens uses the keyring from the Cosmos-sdk. There is more information about it [here](https://github.com/cosmos/cosmos-sdk/blob/master/crypto/keyring/doc.go).
To add a key to lens you have two options:
* `lens keys add` - This will add a key to you default chain and name it "default". You can optionally add a name as an argument.
* `lens keys restore ` - This will restore a key to your default chain. Replace '\' with a key name. This command will THEN ask for your mnemonic which is needed to restore and use it to boradcast transactions.
>❗️ NOTE: IF you name your key anything other than "default", you will need to manually change the `key:` value in your config to link key with chain.
>```bash
>default_chain: cosmoshub
>chains:
> cosmoshub:
> key: default #CHANGE THIS NAME
> chain-id: cosmoshub-4
> rpc-addr: https://cosmoshub-4.technofractal.com:443
> ...
>```
After generating or restoring a key, it should appear in your list by running: `lens keys list`, by default it will show the Cosmos Hub address.
To see the key encoded for use on other chains run `lens keys enumerate `.
