# This file is a quick-check of vim-duckscript - it tries to use many
# duckscript idioms in a single screen of text.
# Comments check mai bad spellling with :spell enabled
# TODO is highlighted, as are XXX FIXME WIP TBD

# Commands - built-in should be different than custom functions, which should
# be different from pre-processor commands.
a = echo true 5 -10 +0 -0 ${expansion} %{spread} "string with space" atom # Built-in
b = myfunc true 5 -10 +0 -0 ${expansion} %{spread} "string with space" atom  # Non-builtin
!echo true 5 -10 +0 -0 ${expansion} %{spread} "string with space" atom # Pre-processor
echo keywords shouldn't highlight for if elseif else end fn function

# String escapes are valid both inside and outside quotes

# Labels

echo :label is just text in anything other than goto

# Flow control.

return `return` is a normal atom outside of `fn`
elseif `elseif` is a normal atom outside of `if`
else `else` is a normal atom outside of `if`
