Thank you! I can download latest devel release with following command: curl -s https://api.github.com/repos/nim-lang/nightlies/releases | grep -m 1 "\"browser_download_url\": \"https://github.com/nim-lang/nightlies/releases/download/devel-.*-linux\.tar\.xz\"" | sed -E 's/.*"browser_download_url\": \"([^"]+)\"/\1/' | wget -qi - -O nim.tar.xz Run
I fixed the script that download and build nighly release Nim. [https://github.com/demotomohiro/wandbox-builder/blob/fixnimhead/build/nim-head/install.sh](https://github.com/demotomohiro/wandbox-builder/blob/fixnimhead/build/nim-head/install.sh) I will send PR of this fix to wandbox after testing this for few days. I thought GitHub GraphQL API is better than REST API because I can minimize amount of data receive from GitHub. But GraphQL API require an OAuth token and putting it on public repository is not a good idea.
