Deprecation warnings in dependencies such as litz - add ES module support for Nim 1.x

[kristianmandrup]

Hi,

Been very interested in trying to achieve ES module support with Nim. Found this effort through a Nim forum thread

Just added this Nim issue on the topic as well

I cloned the nes repo and ran a nimble install

/private/var/folders/gy/_6733lds2dg8m3_fg0z_yvw40000gn/T/nimble_15271/githubcom_zacharycarterlitzgit/src/litzpkg/tagdef.nim(52, 33) Warning: Deprecated since v0.20, use 'toHashSet'; toSet is deprecated [Deprecated]

Loads of deprecation warnings for the litz package (since 0.20). Let's see if we can fix these so we can add proper ES module support for Nim 1.0

I have started extracting ES 2015 class support and Custom Elements into separate repos

• nim_es2015_classes
• nim_custom_elements

You mentioned that you've also managed to achieve ES module support for Nim?
