Switching a mode can cause a `ParseError`

gimpf commented 4 years ago

When using a voice command to switch from command to dictation mode a ParseError can occur.

in-command-mode.talon:

mode: command
-
^switch to dictation mode$:
    mode.disable("command")
    mode.enable("dictation")

in-dictation-mode.talon:

mode: dictation
-
^switch to command mode$:
    mode.disable("dictation")
    mode.enable("command")

When voicing "switch to dictation mode", the following will show up in the log, and the new commands are not available:

   20: ------------------------------------# 'update' main:update_one()

talon.grammar.parser.ParseError:   Line: 1, Column: 47 - unexpected token
      (<_switch_to_command_mode_>|<_talon_sleep_> | )

Workaround: Not using start/end phrase anchors (^, $).

This might only happen if there are only anchored commands in the file.
