Hello ! Try it online here https://meimporta.eu/myglpk-ext
After looking around and with the help of the author of https://www.strandmark.net/wasm/glpk.html I managed to compile https://github.com/mingodad/GLPK/tree/local-set-param to wasm and make it available here https://meimporta.eu/myglpk-ext for anyone to experiment with the extensions I made to GMPL/glpsol and if possible give feedback/suggestion/comment.
Cheers !
