I get the following popup in red.
Failed to load snippets from 'C:\Users\18148.atom\packages\language-
julia\snippets\language-julia.cson'
C:\Users\18148\.atom\packages\language-julia\snippets\language-julia.cson:
Duplicate key '.source.julia'
Julia on Hydrogen on Atom runs fine. But I don't want to see this message every time. Thank you.
Just open the file C:\Users\18148.atom\packages\language-
julia\snippets\language-julia.cson. Then there at the top you will see two entries starting with .source.julia. Remove the line 10 ".source.julia": and the error should be fixed.
