These financial tools are several tools I have written for my own use. I have been tracking my personal finances using Ledger since 2014. I have written the following tools to help with this:

• datacleanup: tool in Python to clean up CSV files downloaded from financial institutions
• financial-importer: tool in Rust to generate Ledger entries from CSV files based on rules configured in a TOML file
• pricesdb-updater: tool in Rust to download daily commodity prices from Yahoo Finance and create Ledger supported pricesdb file

• gtkmenu: a GTK dmenu-work-a-like implemented in Haskell.
• XMonad, Gnome, and gtkmenu screencast: YouTube screencast demonstrating gtkmenu.

I previously used myrepos and vcsh to manage my personal software configurations, split up over several GitHub respositories. These configurations were used on Linux, primarily NixOS.

This configuration was split up over the following public repositories, plus some private repositories for secrets and other private configuration:

• vcsh_mr: the manyrepos configuration.
• vcsh_cli-misc: Miscellaneous CLI tool configuration.
• vcsh_emacs: modular configuration for Emacs (Spacemacs).
• local-nix: modular NixOS configuration used across 4 machines.
• vcsh_shell: Modular shell configuration.
• vcsh_X: configuration for X and related tools.

Metaproject was an implementation of basic project support for Emacs. It was intended to be similar in features to the newer and now popular Projectile project.

Informant was a set of utilities for keeping a user informed of events. It consisted of an informant, which is the means by which the user is alerted to the occurrence of the said event, and a number of sources that "whisper" an alert to the informant when the event occurs.

It was implemented as a Gnome Panel applet or a stand alone Gtk program in the Python programming language and used the Twisted network programming framework.
