#1207 LexCPP C++0x raw strings glitch

[Kein-Hong Man]

Failed for this kind of snippet (from luaconf.h, Lua 5.2 beta):

LUA_LDIR"?.lua;"

The raw string tests in SCE_C_IDENTIFIER work, but once it switches back to SCE_C_DEFAULT, the SCE_C_DEFAULT to SCE_C_STRINGRAW transition seems to be too permissive. Recent hg build.

[Neil Hodgson]

Possibly a check that the 'R' is in SCE_C_STRINGRAW state.

[Kein-Hong Man]

Changing the line to:

if (sc.chPrev == 'R' && styler.StyleAt(sc.currentPos - 1) == SCE_C_STRINGRAW) {

Works, but one glitch when editing: add a space or char between R and the "(string)", then delete the char. Then "(string)" stays a regular string. Possibly need something like the HEREDOC refresh you did for the Perl lexer...

[Neil Hodgson]

Because the style of the previous byte is still in a buffer, it isn't seen by StyleAt. Adding in a Flush fixes this:

if (sc.chPrev == 'R') {
styler.Flush();
if (MaskActive(styler.StyleAt(sc.currentPos - 1)) == SCE_C_STRINGRAW) {

It may be better to either improve StyleAt so it looks into the buffered styles or add another method.

[Kein-Hong Man]

Good catch, editing work fine now.

[Neil Hodgson]

Committed fix.
