Mineclonia is a fork of MineClone2, last time I tried them, they were quite simmilar (obviously). As far my experience goes, the saves are not 100% compatible (textures broke, but it remembered blocks) and same with the mods, some work, some fail. I would try both.
I play with it sometimes, kinde like some of the syntax, especially regex and ;.
I tried doing regex with sed when working on one personal script, but was getting errors way too often everywhere. Perl did what I wanted in a few lines and gave me desired output, so I just used that.
Imo, it doesn't really matter what you use for writing code for your personal use as long as it works. : )
I have tried both, Libresprite is nice, but I am more used to working with Krita, alhough my laptop really dislikes it and heats up. Was not an issue when it was booting Linux so an OS issue I guess.
Libresprite is obviously more plug and play experience.
Krita has a decent pixel art support, but requires a bit of setup. Some tools have Antialiasing option in Tool options docker, so you may play around with that, if your selections and fills are getting messed up. It has some pixel brushes, but if you decide to stick with it for a while I would recommend making some brushes and patterns for pixelart on your own as well, just for the sake of convenience. Also make sure to customize your dockers (UI).
I am unfortunately so used to vim and its bindings that I suffer whenever I can't use it. It can be really tricky to do certain operations in other editors.
Buying some with needle that's roughly 1-2mm on diameter is relatively easy and it does not even need to be meant for glue (depending on what glue you use of course)
I would copy the text to a .txt file (maybe edit it to make the width more mobile friendly) and on phone open it with some basic text editor.
I use MiXplorer (the free version from XDA) as a default file manager and find it's Text editor quite good.
Other good options may be Markor (since it has edit and view modes, but make sure to turn off text wrapping) or other editors.
Code editor like Acode would be an overkill for this.
Last but not least, you can also screenshot the tab or copy it to some word processor, set font to monospace and export as .pdf (maybe with custom document size if more convenient)
I just felt that many people may get lost in it when first using it, the same way ppl get lost in vim. At least I managed to get lost in both of them when I first tried them.
There's a browser extension for IA books. Haven't tested, but has source on github.
