For the moment we're also retaining the old ones. Not sure when will be the best time to get rid of those; after the next release, perhaps?

|
|
* These argument-breaking rules apply to Visual Studio 7, which
|
|
* is currently the compiler expected to be used for PuTTY. Visual
|
|
* Studio 10 has different rules, lacking the curious mod 3
|
|
* behaviour of consecutive quotes described below; I presume they
|
|
* fixed a bug. As and when we migrate to a newer compiler, we'll
|
|
* have to adjust this to match; however, for the moment we
|
|
* faithfully imitate in our GUI utilities what our CLI utilities
|
|
* can't be prevented from doing.
|
|
*
|
|
* When I investigated this, at first glance the rules appeared to
|
|
* be:
|
|
*
|
|
* - Single quotes are not special characters.
|
|
*
|
|
* - Double quotes are removed, but within them spaces cease
|
|
* to be special.
|
|
*
|
|
* - Backslashes are _only_ special when a sequence of them
|
|
* appear just before a double quote. In this situation,
|
|
* they are treated like C backslashes: so \" just gives a
|
|
* literal quote, \\" gives a literal backslash and then
|
|
* opens or closes a double-quoted segment, \\\" gives a
|
|
* literal backslash and then a literal quote, \\\\" gives
|
|
* two literal backslashes and then opens/closes a
|
|
* double-quoted segment, and so forth. Note that this
|
|
* behaviour is identical inside and outside double quotes.
|
|
*
|
|
* - Two successive double quotes become one literal double
|
|
* quote, but only _inside_ a double-quoted segment.
|
|
* Outside, they just form an empty double-quoted segment
|
|
* (which may cause an empty argument word).
|
|
*
|
|
* - That only leaves the interesting question of what happens
|
|
* when one or more backslashes precedes two or more double
|
|
* quotes, starting inside a double-quoted string. And the
|
|
* answer to that appears somewhat bizarre. Here I tabulate
|
|
* number of backslashes (across the top) against number of
|
|
* quotes (down the left), and indicate how many backslashes
|
|
* are output, how many quotes are output, and whether a
|
|
* quoted segment is open at the end of the sequence:
|
|
*
|
|
* backslashes
|
|
*
|
|
* 0 1 2 3 4
|
|
*
|
|

|
|
*
|
|
* There is very weird mod-3 behaviour going on here in the
|
|
* number of quotes, and it even applies when there aren't any
|
|
* backslashes! How ghastly.
|
|
*
|
|
* With a bit of thought, this extremely odd diagram suddenly
|
|
* coalesced itself into a coherent, if still ghastly, model of
|
|
* how things work:
|
|
*
|
|
* - As before, backslashes are only special when one or more
|
|
* of them appear contiguously before at least one double
|
|
* quote. In this situation the backslashes do exactly what
|
|
* you'd expect: each one quotes the next thing in front of
|
|
* it, so you end up with n/2 literal backslashes (if n is
|
|
* even) or (n-1)/2 literal backslashes and a literal quote
|
|
* (if n is odd). In the latter case the double quote
|
|
* character right after the backslashes is used up.
|
|
*
|
|
* - After that, any remaining double quotes are processed. A
|
|
* string of contiguous unescaped double quotes has a mod-3
|
|
* behaviour:
|
|
*
|
|
* * inside a quoted segment, a quote ends the segment.
|
|
* * _immediately_ after ending a quoted segment, a quote
|
|
* simply produces a literal quote.
|
|
* * otherwise, outside a quoted segment, a quote begins a
|
|
* quoted segment.
|
|
*
|
|
* So, for example, if we started inside a quoted segment
|
|
* then two contiguous quotes would close the segment and
|
|
* produce a literal quote; three would close the segment,
|
|
* produce a literal quote, and open a new segment. If we
|
|
* started outside a quoted segment, then two contiguous
|
|
* quotes would open and then close a segment, producing no
|
|
* output (but potentially creating a zero-length argument);
|
|
* but three quotes would open and close a segment and then
|
|
* produce a literal quote.
