Reading over LangChain

LaraChain.io

And just thinking how to make some of those flows work in a Laravel environment

Links

The PHP Vector library

Setup

Make sure to have .env in place before running sail up

Follow the Sail Laravel docs eg sail up for Postgres only the rest is just normal Laravel. The brew install did not work on my M2

Seed the user:

Update your .env file:

ADMIN_EMAIL=foo@bar.com
ADMIN_PASSWORD=foobaz

This just helps since Jetstream requires a team etc to work.

php artisan migrate
php artisan db:seed --class=UserSeeder

Migration Note

$table->integer('token_count');
$table->vector('embedding', 1536)->nullable();

php artisan feature:on database larachain_logging

Forking to Private repo.

Here are some docs from ChatGPT that I am still testing:

Yes, you're correct that on GitHub, you cannot create a private fork from a public repository. But there's a workaround for this. You can effectively create a "manual" private fork by duplicating the repository. Here's how to do it:

1. Create a new private repository on GitHub. This will be your private "fork."

2. Clone the public repository to your local machine:

   git clone https://github.com/original_owner/original_repo.git

3. Navigate into the directory that was just created (it will have the same name as the repository):

   cd original_repo

4. Remove the link to the original repository:

   git remote remove origin

5. Link the local repository to your new private repository:

   git remote add origin https://github.com/your_username/new_repo.git

6. Push the local repository to your private repository:

   git push -u origin main

You now have a copy of the public repository as a private repository on your GitHub.

When the public repository gets updates, you can merge them into your private repository by adding the public repository as a remote:

git remote add upstream https://github.com/original_owner/original_repo.git

Then, you can fetch the updates:

git fetch upstream

And merge them into your private repository:

git merge upstream/main

Or, if you want to rebase (apply your changes on top of the fetched changes):

git rebase upstream/main

Then, push your changes to your private repository:

git push origin main

That's it! This will allow you to have a private "fork" of a public repository and to merge updates from the public repository into your private one.
