Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe/recipe.yaml) and found some lint.

Here's what I've got...

For recipe/recipe.yaml:

• ❌ The top level meta key schema_version is unexpected
• ❌ There are 1 too many lines. There should be one empty line at the end of the file.

I've merged conda-forge/lua-lpeg-feedstock#13, and will push fixes to this locally in a little bit after there has been enough time for the Windows build of lua-lpeg to become available.

Before merge I'm also going to test locally if there's any way to fix that permissions error in Windows that prevented the use of cmake install. If I can't figure it out quickly I'll just merge as is.

Well that's unexpected, now macOS and Windows are working but Linux is failing with this rather arcane error:

$SRC_DIR/src/nvim/po/ja.euc-jp.po: warning: Charset "EUC-JP" is not supported. msgfmt relies on iconv(), and iconv() does not support "EUC-JP". Installing GNU libiconv and then reinstalling GNU gettext would fix this problem. Continuing anyway.
$PREFIX/bin/msgfmt: Cannot convert from "EUC-JP" to "UTF-8". msgfmt relies on iconv(), and iconv() does not support this conversion.

I have added libiconv as a dependency on Linux but that doesn't actually fix the issue, so the suggested fix doesn't actually help. I'll continue debugging this locally to see if I can figure out the fix.
