Made a few quality-of-life improvements to https://regular.express today (my visual regular expression tool):

• Character sets are rendered more clearly, have improved keyboard navigation, and can now be negated (putting a ^ at the beginning).
• Keyboard shortcuts should work correctly on macOS.
• More regex syntax is parsed and passed through even when it cannot be edited, making the tool more useful for quick edits to existing regexes.
• I also removed 12MB of zeroes from the executable that LLVM left in there for some reason.

I can now compose this entire regex in my visual regex builder without touching the mouse. This is pretty exciting to me - this tool should be useful for both beginners and power users.

Hand-writing some WASM for fun. This is a memchr implementation that is being used to check if the character following a backslash is a valid "metacharacter" in a regex. No real reason to write this in WASM directly except to learn it better.

Making text input feel right is a lot of work, but it's paying off. This video demonstrates the same cursor and selection code being applied to two separate data structures, neither of which is a buffer of chars.

Tonight I made my regex builder distinguish between "insert index" and "cursor index/position", which allows me to display the cursor on the right or left side of an element without affecting how inserts and deletes work.

Visual regex builder: now 200% prettier and rounder. (Gotta file down those sharp edges!) Also now has a bunch more keyboard shortcuts; I think when this is done it will be really powerful even without the mouse.
