I’m looking for a plain text editor for an iPad. Everything I’ve come across seems to be targeted at writing markdown files with a .md file extension. I need to edit other file “types” — .Rmd, .sql, .r and, of course, .txt. A code editor would be ideal, but I don’t know any for iOS.
I use iA writer on phone, iPad and Mac. Saves as .txt. … I imagine it can edit anything (that is text based). Not sure if it insists on using .txt when re-saving a document though. I’d hate for you to be stuck with “document.r.txt” or something.
Another vote for Textastic. Excellent syntax highlighting, built-in terminal, well-done integration with Files. Only downside is that it’s not scriptable, but I’ve been surprised to find myself not missing that… much.
