Subject: [jdee-users] Proposed patch to build.xml for MSWindows double-quote escape-char (msw-dqec)

Hello,

Please find attached a patch proposal for jdee/build.xml.

The problem at stake is that which I reported to Ant as:

http://issues.apache.org/bugzilla/show_bug.cgi?id=54285

My understanding of the problem is the following one:

- MSDos command line has arcane and poorly documented rules for escaping
  special characters:
  - inside double quote the escape char is \ and you need to escape "
    and \, however most of the time not escaping \ will work because a
    single \ is interpreted as \ also
  - percent sign have to be double quoted as ^%, but outside of the
    double-quotes
  - example:

        a\string%to\\be quoted %% now

    would be double-quoted as:

        "a\\string"^%"to\\\\be quoted "^%^%" now"

- Ant does not do anything special to quote properly arguments passed to
  command. This means that any double quote in the argument will cause
  havoc

- is that a bug of Ant or of the JVM:
  - my understanding that that is a little of both
  - the standard Java library should provide some support to process a
    string into a quoted string for the platform on which the program is
    run, like File.separator depends on the platform on which the
    program is run --- to my knowledge there is no such support
  - Ant should call such standard library function --- if it was
    existing to do the argument quoting properly


- the hack which I propose is to do the escaping by hand within the
  build.xml. Of course as soon as Ant is corrected for this problem,
  then build.xml will need further patching so that property msw-dqec is
  set to empty string when Ant version is recent enough.


VBR,
  Vincent.
