Define recurring bills & income, and get a fairly accurate prediction of where your finances will be in the future.

This is a terminal user interface-based application (TUI).

Installation

Either visit the Releases page to download a precompiled binary, or alternatively, if you have Go installed you can just run go install:

go install github.com/charles-m-knox/finance-planner-tui@latest

Then just run

finance-planner-tui

Note that if you are running this e.g. inside a Docker container or a limited shell, your TERM environment variable may restrict the number of colors that Finance Planner TUI can use. Consider setting it to something like TERM=tmux-256color:

TERM=tmux-256color finance-planner-tui

Features

• uses a simple yml configuration format for files
• minimal resource usage footprint (measured around 10-20MB memory usage on Linux)
• sensible default keybindings
• translation support (currently only en_US.UTF-8 implemented but other languages can create new files under translations/*.yml)
• custom color support

Usage & information

The following sections are basically just copy/pasted from the Help (F1 or ?) page in the application itself. It is better to view it there.

Profiles

Profiles are shown on the left-hand side of the Profiles & Transactions page.

• You may need to use the <tab> key to get to them.
• You can duplicate and rename profiles.
• Each profile must have a unique name. Duplicate names will be refused.

You can create multiple profiles to fulfill any purpose, such as:

• modeling a change in your financial plans (removing subscriptions, hypotheticals, etc)
• adding multiple family members

Transactions

A transaction is a recurring expense or income:

• If the transaction earns money, it is prefixed with a + (plus) sign.
• All transactions are assumed to be negative by default.

Each transaction has the following fields:

• Amount: This is a positive or negative value as described above.

• Active: This is a boolean value that determines whether the transaction should be included in calculations. This is useful for temporarily making changes without destroying anything.

• Name: This is the human-readable name of the transaction for your eyes.

• Frequency: Transactions can occur MONTHLY, WEEKLY, or YEARLY. This value must be exactly one of those three strings, but an auto- complete is provided to make it quicker.

• Interval: The transaction occurs every <interval> WEEKS/MONTHS/YEARS.

• <Weekday>: The transaction only occurs on the checked days of the week, and will not occur if the defined recurrence pattern does not land on one of these days.

• Starts: This is the starting date for the transaction's recurrence pattern. It is defined as YYYY-MM-DD.

  For simplicity when working with dates at the end of the month, you may want to consider putting setting the day value to 28, as some recurrence patterns may skip a 31.

  Months range from 1-12, and days range from 1-31. Years must be any positive value, and can be 0.

• Ends: This is the last acceptable date for recurrence. Behavior is the exact same as the Starts field.

• Note: A human-readable field for you to put arbitrary notes in.

Results

The results page allows you to see a projection of your finances into the future. It shows the following:

• A form on the left containing start & end dates, and the starting balance for the projection to start with
• A table containing one day per row, with each of the transactions that occurred on that day, as well as other numbers such as the total expenses, running balance since the first day of the projection, etc.

The same hotkey that opens the results page can be pressed multiple times to re-submit the results form and will also show some useful statistics about your finances.

Keybindings

Press F1 while in the application or ? and use the up/down keys to view the keybindings that are activated & defaults. Note that F1 and ? keybindings can be changed.

Wish/todo/broken list

• when sorting, the LastSelectedIndex does not seem to work
• fix no sorting for Note column
• weekday sorting only sorts for Monday
• when hitting Enter on a row, if there are other things selected, also select this row
• change all refs to c.Reset to tcell.ColorReset
• debug config.yml loading errors
• create xdg config dir when loading configs
• finish translations into english
• allow disabling mouse support so that things can be copied (config propery, or even through a shortcut?)
• ctrl+F and / for search
• Home and End keys should navigate to the top left & bottom right columns when already at the leftmost column/row
• write debug logs to xdg cache dir
• remind users that the Tab key is used for navigating through the results form
• update help file to show actual keybindings
• customize colors (later!)
• fix issue on mac with showing black on black in results page

Warnings/disclaimers

• The stability of this software is increasing as time goes on, but you should make reasonable efforts to double check the output of this program.
• As with many of my personal projects, the code in this project contains a lot of experimental approaches to writing software that I might not otherwise have taken in a professional/serious environment. Please do not judge it in that regard.
