How to Install Fava on OpenBSD

Fava is a web interface for the double-entry accounting system, Beancount. This tutorial will guide you through the process of installing Fava on OpenBSD.

Prerequisites

Before installing Fava, make sure that your OpenBSD system is up-to-date and has the necessary dependencies installed. You will need Python 3.6 or higher and pip3 installed on your system. You can verify whether you already have these installed by running the following commands in your terminal:

$ python3 --version
$ pip3 --version

If you don't have these installed, you can install them using the package manager, pkg_add.

$ sudo pkg_add python3 py3-pip

Installing Fava

Now that you have the necessary prerequisites installed, you can proceed to install Fava.

Install Fava using pip3.
```
$ sudo pip3 install fava
```
Create a new directory to store your Beancount files and navigate to it in your terminal.
```
$ mkdir bean_files
$ cd bean_files
```
Create a new Beancount file using your preferred text editor. For example, using vi.
```
$ vi example.beancount
```

Add some sample data to your Beancount file. For example:

2020-01-01 open Assets:Checking
2020-01-01 open Equity:Opening-Balances
2020-01-01 * "Initial balance"
  Assets:Checking 1,000.00 USD
  Equity:Opening-Balances

Save and exit the file.
Initialize the Beancount file.
```
$ bean-check example.beancount
```
This will initialize your Beancount file and create a .beancount.input file.
Start the Fava server.
```
$ fava example.beancount
```
This will start the Fava server on your localhost on port 5000.
Open your web browser and navigate to http://localhost:5000. You should see the Fava interface with your sample data.

Congratulations! You have successfully installed Fava on OpenBSD and can start using it to manage your double-entry accounting system.
