These projects are for Linux unless otherwise stated, although they may or may not work on other platforms.
Count: This is a python script that counts the files and directories in the current directory.
Countdown timer: This is a python command-line countdown timer.
Ki: Ki is a command-line app that allows you to access and create organized index-like content conveniently without painfully navigating through directory structures. It allows for symmetric encryption, choosing what app to open files with, and so forth. You can also name paths so you can go to them by that name. You may want to use this short bash script to make that even easier. To name a directory, enter it on the command-line and then type `ki -B`; select `a` and choose a name.
Language Checker (LangCheck) This Python script allows you to quickly evaluate the language and content of a text (it checks against things like profanity [including religious profanity], insults, drugs, gambling, violence, and sex) to see how family-friendly it is. It does require some education to use properly. It doesn't do all the work for you; it merely simplifies and considerably shortens the process. You run the text (or link) through the program and it generates a list of words that may or may not be concerning to you. You can look up the ones that might be concerning to you in the text to see if they're a problem. While it might seem a bit rough, it's remarkably effective at catching concerning language. It goes by the motto that it's better to catch things that aren't concerning than to miss things that are (that's why you have to evaluate the list yourself instead of letting it do all the work for you; another reason is that you're responsible for your own conscience; so, you decide which words make it). Trigger warning: the source code obviously needs to contain foul language in order to check for it (I don't recommend you peruse it). I imagine this would work on other platforms besides Linux, too.
Manual Chess: This is a manual Chess set in Python (using Tkinter for the GUI), made with the assistance of ChatGPT. It's designed to allow you to use the board and pieces however you want, so you can make up your own Chess variants and similar (it also allows you to play many current ones). There's no computer opponent, and it doesn't tell you how to move your pieces. See the source code for instructions on how to use it, including keyboard shortcuts. To load it, copy and paste the source code into a plain-text file and run it with Python 3.x. It's just one file (no images). I imagine this would work on other platforms besides Linux.
Manual Chess (web edition): This is version 0.2.3 of a JavaScript version of the above Python program with a few alterations (ChatGPT did the vast majority of the programming, translating from the Python app, with guidance from me). So, now you can play it in your web browser; just click that link. It has actual Chess pieces instead of letters. You can't put non-Chess pieces on the board. The keyboard shortcuts are a little different. You have to control+click to remove a piece instead of a double-click. It has some buttons. Other than that, it's about the same. Use s and w, and i and k to increment and decrement the score. Use h to shuffle and f to flip. You have to press the New Game button to restart the game. Like the Python version, it's just one file, with no images (the Chess pieces are Unicode characters). This app does not work with a touchscreen, yet. You can't change the board size, yet. This should work on other platforms besides Linux, but I haven't tested any. Bug: You can't drag a new piece from the panel to a spot you just vacated (but you can move it somewhere else and then move it there).Mark's E-book Reader (MER): This is an old plain-text e-book reader or file pager that I made in Vala years ago. The source code doesn't compile on modern computers due to software updates (this is one reason I stopped using Vala and pretty much focused on Python after that. Nevertheless, you might be able to get it to run if you install some old dependencies (read the instructions for which ones you might want, if you use such as Ubuntu, Linux). The download does include a .exe binary for Windows, but I don't know if it works. I don't usually use this app anymore, but I do like how it handles margins (that seemed more difficult to replicate in Tkinter last I checked, before ChatGPT existed).
Shule (version 0.2.0): Shule is a Linux text editor, authoring station, IDE, and plain text e-book reader. I personally find it very useful. It's written entirely in Python 3.x, using Tkinter. Some remarkable features include the ability to save and load favorites (by typing in a favorite name, but not by selecting it in a menu; a favorite is a named set of one or more filepaths on your computer); the ability to password-protect documents; sort ascending/descending, shuffle, reverse; change casing (uppercase, lowercase, title case); indent/unindent selection; ability to type special characters; open a terminal at the current file location; open a file manager at the current file location; customize fonts and colors; countdown timers and stopwatches; document statistics; fullscreen mode; bullet/number and unbullet/unnumber selection; timestamp; auto-indent; and so on. Shule works best when you're using a keyboard with a menu key, two windows keys, and insert key (used for compose keys), such as this one; however, you can reconfigure the compose keys if your keyboard isn't like that. It's currently optimized for Xubuntu 22.04.4 LTS. Often when a new Xubuntu version is released something needs to be edited having to do with the GNU Privacy Guard integration before it will work properly (GPG seems to change a lot). See the changelog.
Wikiweb: Wikiweb is database software (a library, mostly) that is designed to allow you to make complex two-way linking structures simply. You can do text-only data entry, and export your project to HTML, too. There are some features implemented for game design, too, such support for JavaScript to be run in the exported HTML when you click on links. This is a library (not an app). Wikiweb is a misnomer; it's not wiki software (the reason for the name is that it provides a data structure the likes of which would be nice if used in a wiki context, since it's a lot more flexible than a wiki-style category; but it's not for wikis particularly).
