Re: [Dev-luatex] Feature request: busy pdf

I see. This should be documented properly, thus I should not have wasted my time and yours.

Sorry, last answer was too short… The problem is not that the new pdf output is not complete until the end of the typesetting process, the problem is that the old pdf is removed at the beginning of the typesetting process, whereas it could be removed only at the very last moment. This would be a big improvement in everyone’s workflow (overleaf uses that de facto).

In a work flow one can rename and such. In context that has been done for decades so I bet overloeaf can also do it. Workflows are not part of 'tex the program' as they differ and fighting built-in heuristics is a pain (already).

I agree that luatex callbacks can be used for that purpose, but it means that each people must have some basic lua skills and will have to modify all its documents one by one. Using the ‘--lua’ options is a bit better, except that every one must still duplicate the initialization file in each document folder. Anyways, this is rather far from a user friendly one click solution.

It should be no big deal to make it part of the macro package used (likely latex); just add the few lines of (lua) code needed to do it as part of th enormal lua related initializations. That way (1) users don't notice and (2) some --flag can be used that doesn't conflict.

This should be in the TODO list, not at the top, but not very far… BTW, I have found luatex roadmap on the web but no task list, was I Per 1.10 LuaTeX is frozen because otherwise it's hard for macro package writers and users to keep up with the changes. As extensions can be done in Lua it also moves the responsibility to those who use it while the luatex team handles bug fixes and integration in tex live. That site is mostly there for historic reasons.
