Get started (~ 2min)

Install Continue extension (tested with VSCode extension).

Clone this reposiroty in your ~/.continue/ directory

cd ~/.continue/
git clone https://github.com/NoeSamaille/continue-watsonx.git

Make a local copy of your local Continue config:

mv ~/.continue/config.ts ~/.continue/config-backup.ts

Copy the provided config-sample.ts to replace ~/.continue/config.ts:

cp ~/.continue/continue-watsonx/src/config-sample.ts ~/.continue/config.ts

or, if you have customized your config.ts, manually add the code to load the Watsonx module and use Watsonx.addConfig():

import {watsonx_modifyConfig} from "./continue-watsonx/src/watsonx"; 
export function modifyConfig(config: Config): Config {
    return watsonx_modifyConfig(config);
}

Copy src/watsonxenv.ts.sample to src/watsonxenv.ts and update WatsonxEnv with your target configuration:
```
cp ~/.continue/continue-watsonx/src/watsonxenv.ts.sample ~/.continue/continue-watsonx/src/watsonxenv.ts
```
1. If using watsonx SaaS:
  - Replace YOUR_WATSONX_URL with your watsonx SaaS endpoint, e.g. https://us-south.ml.cloud.ibm.com for US South region.
  - Replace YOUR_WATSONX_APIKEY with your watsonx API Key.
  - Replace YOUR_WATSONX_PROJECT_ID with your watsonx project ID.
2. If using watsonx software:
  1. Option 1: using username/password authentication:
    - Replace YOUR_WATSONX_URL with your watsonx software endpoint, e.g. https://cpd-watsonx.apps.example.com.
    - Replace YOUR_WATSONX_USERNAME with your watsonx username, e.g. cpadmin.
    - Replace YOUR_WATSONX_PASSWORD with your watsonx password.
    - Replace YOUR_WATSONX_PROJECT_ID with your watsonx project ID.

    - Replace YOUR_WATSONX_PROJECT_ID with your watsonx project ID.
- - Note: if using watsonx software instance with self-signed/untrusted TLS certificates, uncomment the following lines in ~/.continue/continue-watsonx/src/watsonx.ts to bypass SSL certificate verification:
```
declare var process : {
    env: {
        NODE_TLS_REJECT_UNAUTHORIZED: any
    }
}
process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0;
```
1. Optionally, update models to comment/uncomment/edit model list based on LLMs deployed in your watsonx instance.
Enjoy!
