# Lazy finance (lbud for "lazy budget")

[![PyPI version](https://badge.fury.io/py/lazy-budget.svg)](https://badge.fury.io/py/lazy-budget)

`lbud` aims to help building an easy, data-driven budget solution for personal use.

For examples of data, see `example-data/`.

## Setup

```bash
python3.9 -m pip install lazy-budget
```

## Workflow

`lbud` works in a very specific way: you declare

- the budgeting period (start and end date)
- how much money do you have (as of the first day of the budgeting period),
- how much do you wanna save (as of the last day of budgeting period),
- your financial operations.

Provided with the data described above, `lbud` allows you to see certain statistics over time, answers to these questions:

- How much more money can I actually spend today?
- How much money do I spend daily on average?
- When I spend too much money, for how many days should I limit my spendings to keep the money I set out to keep?

To start using `lbud` to manage your budget,
you will need to create and
maintain at least 2 text files.

### Budget file

`budget.yml` is a YAML file that describes a single budgeting period. It is advised to keep the period short, but i am sure `lbud` can handle however long budgets. Example:

```yaml
# total amount of money to use
total: 2000

# the part of the total
# that you aim to keep this month
keep: 1500

# budgeting period
start: 2021-04-25
end: 2021-05-10

# currency is optional
# USD is the default and
# the operations themselves can
# specify the currency (lbud add "-10 CAD" taxi), as well
# as the config file and CLI options
currency: USD
```

### History file

`history.csv` is a CSV file that lists all of your financial operations. You may have one history file for all your budgets, history is filtered by budget period when performing calculations.
It has to have following columns:

- `money_value` - operation value; may include a currency in multi-currency setups, format: `-10.99 CAD`;
- `description` - operation description; may include category, format: `[category] description`;
- `dttm` - operation date and time, ISO format.

Example:

```csv
-10,[food] snacks,2021-04-26T00:00:00
-1.95,[food] bubblegum,2021-04-27T17:20:31
-9.95,[food] hot dog,2021-04-27T00:00:00
-3.33,donation,2021-04-28T00:00:00
-30,[medicine] cardiologist,2021-04-29T00:00:00
```

### Use of `lbud` on example files

```bash
$ lbud ls
           today : 2021-05-01
      total days : 16
       days left : 9
 available / day : $31.25
 CAN spend today : $163.52
     spent today : $0.00
 avg spent / day : $7.89
            kept : $1,663.52

$ lbud add -200 "club night"

$ cat history.csv  # added operation to history file
-10,[food] snacks,2021-04-26T00:00:00
-1.95,[food] bubblegum,2021-04-27T17:20:31
-9.95,[food] hot dog,2021-04-27T00:00:00
-3.33,donation,2021-04-28T00:00:00
-30,[medicine] cardiologist,2021-04-29T00:00:00
-200,club night,2021-05-01T00:00:00

$ lbud ls
                today : 2021-05-01
           total days : 16
            days left : 9
 days until can spend : 2
      available / day : $31.25
   CANNOT spend today : $36.48
          spent today : $200.00
      avg spent / day : $36.46
                 kept : $1,463.52

$ lbud cats
      medicine : -30,00 USD
          food : -21,90 USD
 <no category> : -3,33 USD
```

## Charts

### Burndown chart

Provides a bird's eye view of how things are going with the budget.

```
$ lbud bd
```

![burndown chart](https://gitlab.com/oleksandr.zelentsov/lazy-finance/-/raw/91dba12f302ea0b2ad2464c60aa7173de6d7acdc/img/bd.png 'Example burndown chart')

### Category chart

Allows to determine how much money was spent/earned by which category.

```
$ lbud catc
```

![category chart](https://gitlab.com/oleksandr.zelentsov/lazy-finance/-/raw/91dba12f302ea0b2ad2464c60aa7173de6d7acdc/img/catsc.png 'Example category chart')

## CLI help

**Note**: all the defaults can be pulled from a config file at `~/.lbudrc.yml`.
To override the location, specify `LBUDRC` environment variable.

```

```

## Weird configuration stuff

There is a lot of configuration options to `lbud`
(CLI arguments, config file, the defaults)
and since it was tested and used
in a very specific way, it might not work for you.

Feel free to [submit a ticket](https://gitlab.com/oleksandr.zelentsov/lazy-finance/-/issues/new) or a pull request (idk if it works, i'm new to this open source thing, please post a ticket about it too).

Posting the way it is actively being used for clarity:

- budget/history files at `~/finances/`
- config file at `~/.lbudrc.yml`:
  ```
  history_file: /Users/oleksandr/finances/history.csv
  budget_file: /Users/oleksandr/finances/budget.yml
  locale: pl_PL
  currency: PLN
  ```
- `lbud` anywhere
