Error when trying to reload TypeScript files

[lostfictions]

Hey there -- I realize this is obviously isn't the fault of your type definitions, but I'm getting an odd error when I try to use Lurker and modify my TypeScript files (while running tstl -p tsconfig.json --watch):

[lurker] Hotswapping 'conf.lua'...
[lurker] Swapped 'conf.lua' in 0.00053299999999989 secs
[lurker] Hotswapping 'guy.lua'...
[lurker] Swapped 'guy.lua' in 0.001142 secs
[lurker] Hotswapping 'lualib_bundle.lua'...
[lurker] Failed to swap 'lualib_bundle.lua' : node_modules/lume/lume.lua:693: table index is nil

Oddly, if I modify the output Lua files directly, things seem to work fine (more or less -- it doesn't crash, but it doesn't always seem to hotswap correctly).

Do you happen to have any insights about what might be happening?

This seems to fix the issue for me:

import lurker = require("lurker");
lurker.preswap = (f) => f === "lualib_bundle.lua";

For whatever reason, tstl's support library seems to choke Lurker.

Thanks for the find!

Looks like lurker can't hotswap code like this:

local Symbol = {}
Map = {}
Map[Symbol] = Map

Not sure if this is a bug with lurker, but the lualib_bundle uses code like this to define classes

So it looks like your solution is the best one for this issue since lurker currently can't handle hotswapping the lualib_bundle

I'll add this step to the README
