This software is designed to be used with editors other than Emacs. If you are
an Emacs user already, I prefer you use Emacs directly.
Here is the list of currently supported editors:
- [Emacs]() (`M-x ellsp-register`)
- [VSCode](https://marketplace.visualstudio.com/items?itemName=jcs090218.Ellsp)

## 🔧 Prerequisites
Before installation, make sure you have all the following software installed!
- [Emacs](https://www.gnu.org/software/emacs/)
- [Eask](https://github.com/emacs-eask/cli)
## 💾 Installation
> [!IMPORTANT]
>
> Ellsp can only be used with projects that utilize Eask as their package manager.
> Ensure your project is properly set up with Eask before using Ellsp.
Add these lines to your `Eask`-file:
```elisp
(source 'jcs-elpa)
(development
(depends-on "ellsp"))
```
Then install the language server:
```sh
# Install ellsp package.
eask install-deps --dev
# Install the proxy server.
eask exec install-ellsp
```
To test to see if the server installed successfully, execute the following command:
```sh
eask exec ellsp
```
If you see the following screen (no error), you successfully installed the language server! 🎉🥳
```sh
Updating environment variables... done v
Exporting environment variables... done v
18:45:59 [INFO ] Starting the language server...
```
*🔊 P.S. Nothing output afterward because the language server is waiting for the
language client to connect!*
## 🔬 Development
To test the language server locally:
```sh
# Add link to current package
eask link add ellsp ./
```
Then follow the same steps as installation:
```sh
# Install the proxy server.
eask exec install-ellsp
# Test the language server.
eask exec ellsp
```
