I meant the value of the ‘foldmethod’ Vim option. What does ‘:set fdm?’ tell you? | :h fdm | :h folding The script sets the fdm option to ‘expr’ for the current buffer/window, which amounts to running user-written code for each line in the buffer. In this particular case, the user-written code is a function named ‘Foldexpr_markdown()’. By the look of it, this function should create a fold automatically wherever it sees a line that starts with an equal sign in column one, followed by either an equal sign or white space. A valid markdown header would be something such as ‘= a header’.. or ‘=== another header’... etc. So that if you if you add a line of the form: ‘= this is a header’ and hit <Enter>, the script should run automatically and create a fold immediately. At least that's the way I understand it. > Maybe this is something Vlad overlooked? Whatever, the workaround is > pretty simple, so thanks again for that. I use a one-line expression to fold Vim help files that is quite similar to the script you referred me to and it updates the folding immediately when for instance I duplicate the first couple of lines of an existing fold by copying and pasting it - I never have to reload the file. At a glance I cannot see any particular reason why the above-mentioned script shouldn't work the same. What exactly do you mean by ‘when I create a file’..? How does it ‘not work’?
