my hhkb settings

hhkb.sh

#!/bin/sh

set -e

# reset
pkill xcape | echo -n
setxkbmap -layout us

# SandS
xmodmap -e 'keycode 255=space'
xmodmap -e 'keycode 65=Shift_L'
xcape -e '#65=space'

# set HHKB keys to super
xmodmap -e 'keycode 102 = Super_L'
xmodmap -e 'keycode 100 = Super_R'

# # Right alt to mod4
xmodmap -e 'clear mod1'
xmodmap -e 'keycode 108 = Super_L'
xmodmap -e 'add mod1 = Alt_L'
xmodmap -e 'add mod1 = Meta_L'

# swap \ and BS
xmodmap -e 'keycode 22 = backslash bar'
xmodmap -e 'keycode 51 = BackSpace'

# swap Esc and `
xmodmap -e 'keycode 9 = grave asciitilde'
xmodmap -e 'keycode 49 = Escape'

# set keyrate
xset r rate 200 100

thanks a lot for this script!
it made my keyboard works well in CentOS.
I have to comment out the xcap line though since my workstation do not have this command.

Your welcome 👍

However, if you do not use xcape command, you should also comment out a couple of lines above the xcape line.
Otherwise, the space key will not work properly.

it seems that I only need these two lines:

xmodmap -e 'keycode 102 = Super_L'
xmodmap -e 'keycode 100 = Super_R'
