readm3 can edit now, and it speaks Reddit

readm3 can edit now, and it speaks Reddit readm3 started as a markdown reader for the terminal. File browser on the left, rendered document on the right. Version 0.3.0 adds the obvious missing half: you can change the file you are looking at. Press e , type, press esc .

A remark and micromark pipeline is somewhere between twenty and forty packages, for a program whose whole point is that it starts instantly in a terminal. Only the parsing moved. The layout code that wraps text, draws code gutters and sizes tables is untouched, so readm3.com still renders through the exact same functions the terminal does. There is still no second renderer. The swap fixed reference links, nested and loose lists, bare URL autolinks and hard line breaks for free. The dialects actually disagree marked does not ship GitHub alerts, footnotes, :emoji: , or anything Reddit added. Those are tokenizer extensions in readm3 now, still with no new dependency. They are behind a --flavor switch rather than all on at once, because the dialects contradic
