man, it's a hot one

smooooth is a service to "hot reload" flake-based nixos configurations.

it will detect changes to the specified path, wait for blockers to resolve, then trigger build + activation of the new config.

blockers can be specified as any executable name. they will prevent reloads until they disappear or change their working directory - this way, smooooth can wait for your current editor/shell/you-name-it session to conclude before rebuilding anything.

the only strict requirement is that said executable handles its cwd properly, so it can be read from the procfs. this may conflict with behaviour of some editors (ie. vscode), particularly if started via a .desktop, instead of in situ.

disclaimer: smooooth is in a very early but entirely functional state. it may be subject to changes, full rewrites, or unending neglect.

enjoy !
