[BUG] Code formatting erases subscripts on operators

[maikonaraujo]

Please search existing issues to avoid duplicates.

Details

• Atom version: 1.39.0 x64
• Julia version: 1.2
• OS: Ubuntu
• Package versions:
  • Atom.jl:
  • julia-client:
  • ink:

Steps to reproduce

1. Type a operator with a subscript:
   2.0 |>ᵦ sin
2. Select the code and press Ctrl+J+F (format shortcut), it erases the beta subscript leaving:
   2.0 |> sin

It is a problem when you implement an operator with a subscript and it get changed when you format your code.

Thanks,

I can't reproduce this. What version of Atom.jl are you using ?
Tell us back what Julia-Client: Debug-Info says.

you just type something like +\_beta(tab) than format the code.

[aviatesk]

we internally use JuliaFormatter package, and maybe this bug is fixed within its latest releases.
Try

pkg> up

and then restart julia, and do the format.

[maikonaraujo]

Just updated as you suggested and same thing is still happening. It is not for all unicode, but when it is used as subscript on operators like:
+\_beta(tab)

what does

pkg> add JuliaFormatter
pkg> st

print ?

[maikonaraujo]

Just try the line below:
+₁ +₂ +ₐ +₊

(v1.2) pkg> st
    Status `~/.julia/environments/v1.2/Project.toml`

  [e5e0dc1b] Juno v0.7.2

[aviatesk]

ok, I figured out what happening:
JuliaFormatter≥0.1.20 requires CSTParser≥1.0.0, but the latest Atom still requires CSTParser≤0.6.3

This is already resolved within our current master branch, so the quick fix for you is

pkg> add Atom#master
pkg> add Juno#master
pkg> add JuliaFormatter#master

---

We may bump Atom.jl version in the near future though.

[maikonaraujo]

That fixed the problem! Thanks!!
