Autocomplete/expansion broken on hyper 2.1.0-canary.2

[andig]

• I am on the latest Hyper.app version

• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: OSX Mojave

• Hyper.app version: 2.1.0-canary.2

• Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere):

  Plugin hyper-snazzy (1.3.0) loaded.
  Plugin hyper-statusline (1.7.6) loaded.
  Plugin hyper-alt-click (0.1.1) loaded.
  Plugin hyperterm-tab-icons (1.1.0) loaded.
  Plugin hyperlinks (0.5.0) loaded.
  Plugin hyperfullscreen (1.0.1) loaded.

• The issue is reproducible in vanilla Hyper.app: Yes- removed all plugins and still present

Issue

Using TAB to complete adds invalid characters to the input. Consider this example where I hit TAB 3 times:

~
❯ cd htdocs/

~
❯ cd htdocs/
zsh: do you wish to see all 104 possibilities (26 lines)?

❯ cdcd htdocs/
Chart.js/                       fritzapi/                       modbus/                         syno-elk/

The 3rd time cd become cdcd. Here is another example how this looks (brbr):

This bug has now made it's way into 2.1.0 (stable).

Any tab completion results in the original input being "pinned" to the input line.
cd then TAB results in:
cdcd

The pinned characters seem to just be a visual artifact and do not affect actual input.
The characters cannot be removed via backspace/delete, you also cannot move the cursor to the characters with the arrow keys.

It has :( I can support testing if there's change but wouldn't know where to start with fixing.

[seanamosw]

Completely uninstalling (brew cask uninstall hyper) and reinstalling seems to have fixed it for me.

[alvinthen]

Reinstalling didn't fix the issue for me, although I'm retaining my .hyper.js, did you generate a new one?

It's a locale issue, see #183

[andig]

#183 was closed as fixed in 2016- seems its back if thats the root cause. I do have these locale settings for sake of reference:

LANG=en_DE.UTF-8
LC_CTYPE=en_DE.UTF-8

[Sbax]

Just tried with those locale settings and I'm also having issues, but I tried with LANG=de_DE.UTF-8 and my current locale LANG=it_IT.UTF-8 without having any problem.

Btw, still broken on canary 3.0 which has just landed today for me.

Fixed by workaround according to #3091 (comment), so #3369 might take care of the root cause.
