|

// 1) wrap the string in quotes

//
|
|
// 2) double-up quotes - i.e. " => ""
|
|
//
|
|
// this is different from the libuv quoting rules. libuv replaces " with \", which unfortunately
|
|
// doesn't work well with a cmd.exe command line.
|
|
//
|
|
// note, replacing " with "" also works well if the arg is passed to a downstream .NET console app.
|
|
// for example, the command line:
|
|
// foo.exe "myarg:""my val"""
|
|
// is parsed by a .NET console app into an arg array:
|
|
// [ "myarg:\"my val\"" ]
|
|
// which is the same end result when applying libuv quoting rules. although the actual
|
|
// command line from libuv quoting rules would look like:
|
|
// foo.exe "myarg:\"my val\""
|
|
//
|
|
// 3) double-up slashes that precede a quote,
|
|
// e.g. hello \world => "hello \world"
|
|
// hello\"world => "hello\\""world"
|
|
// hello\\"world => "hello\\\\""world"
|
|
// hello world\ => "hello world\\"
|
|
//
|
|
// technically this is not required for a cmd.exe command line, or the batch argument parser.
|
|
// the reasons for including this as a .cmd quoting rule are:
|
|
//
|
|
// a) this is optimized for the scenario where the argument is passed from the .cmd file to an
|
|
// external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
|
|
//
|
|
// b) it's what we've been doing previously (by deferring to node default behavior) and we
|
|
// haven't heard any complaints about that aspect.
|
|
//
|
|
// note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
|
|
// escaped when used on the command line directly - even though within a .cmd file % can be escaped
|
|
// by using %%.
|
|
//
|
|
// the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
|
|
// the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
|
|
//
|
|
// one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
|
|
// often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
|
|
// variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
|
|
// to an external program.
|
|
//
|
|
// an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.
|
|
// % can be escaped within a .cmd file.
