What's the definition of control characters?< 0x20?<= 0x20?
per ascii, it is< 0x20.
How should unknown escape sequences be handled? I.e. does "\k"
mean "\k" or "k"?
whatever. it's invalid.
That's the point of the question, what's the preferred action for
dealing with invalid quotes? Should a parser make a best effort attempt
at trying to find out what the user intended, or perhaps refuse to touch
the rest of the file, or anywhere in between?
about the quoting in general, you are confusing things. there are
two distinct layers of quoting: the .ini file quoting and the shell
quoting. the spec concerns the .ini file quoting, with escaping of
control chars and leading/trailing spaces (yes, only these *need*
escaping). what comes out of that for the Exec key is a shell
command and is subject to the shell's quoting rules, and this is
what determines how empty arguments are represented, etc.
I'm aware of the two quoting steps. First, transform the argv to a
string representation, then quote the string to fit into the desktop
entry file format.
The specification doesn't state that the Exec value is a shell command.
The closest you'll get is "command line", which only says that it's,
well, a line with a command. However, since the desktop entry
specification has its own rules for quoting the value of the Exec key,
you can't say that it's a shell command, since the spec for instance
doesn't allow for using '':s for quoting, as for instance bourne shell
allows.
What shell quoting rules are you refering to by the way? As you didn't
specify, perhaps someone will interpret shell command as a tcsh shell
command and quote accordingly to that?
that's how kde implemented it long before the spec was written, and
anyone who thinks something different is meant should be shot. ;)
The problem is that until that is explicitly stated by the spec, your
views are just the opinion of someone on the internet.
