I apologize for the spelling error in the subject of this thread.
I was told that this sentence actually states that lines inside a
(single) command argument cannot end in a line comment.
I initially thought that "Command Arguments" in this sentence means
the "section" that contains all the arguments in a command
invocation,
as the wording implies that there may be multiple lines inside the
referred "Command Arguments".
However, a bracketed or a quoted argument can span several lines, so
the sentence means that one cannot have comments in a bracketed or
quoted argument (the grammar does not allow unescaped "#" inside an
unquoted argument, so I think the sentence does not refer to this
case).
Is this correct?
This is valid:
my_command(
ARG1 # This comment is not part of an argument
# Neither is this
ARG2
)
This is also valid:
my_command(
"ARG1
# But this comment IS part of an argument
"
[==[ARG2
# And so is this
]==]
)
Hope that helps,
Kyle
