watcher gets stuck

[rohal12]

sometimes the watch process gets stuck and the process needs to be restarted.
running bun cross-env NODE_ENV=development bun --watch .build/run_dev.ts in VSCode
on a quite simple project (had it happen on more complex projects as well):

Do you have enableFSLinkCopyOnDevMode: true on your thyweaver.config? (Under builder options)
On my testing, Bun on Windows cannot make the syslinks without exec with admin privilege, Node seams to do it just fine (On win 10 and 11 pro), but I haven't tested on other machine
This option is experimental, as syslinks act strange depending on OS and runtime

[rohal12]

no it is still on false. if I change it to true it will always crash due not being able to do a symlink.

[rohal12]

I updated bun to the latest version and it seems to be running fine so far.
One question though - sometimes the watcher decides to re-build the project while I am in the middle of some unfinished code and just taking a pause to think. Then the compilation process usually stops with some invalid syntax error (not surprising, since I wasn't done with the code yet) and the whole task needs to be restarted. Is there a way to handle this more gracefully?

It's probably related to auto save on your editor, you could try increasing the watcher delay on thyweaver config or disable auto save
