One of my fellow students in the Coursera ChucK class found a bug in chuck --shell under Windows. When using "{" and "}" to enter ChucK code to be interpreted, he got the error: [chuck]: unrecognized escape sequence: \s [chuck]: malformed filename + argumentlist... --> '\s2i8.7'add: error: command failed I tracked it down to util_string.cpp. The extract_args function is interpreting backslashes as the beginning of an escape sequence, not taking into account that Windows file paths can contain backslashes. I made this change which works. I've only done basic testing, though. 266c266,270 < if( s[i] == '\\' && (i+1) < s.length() ) ---

#ifdef __PLATFORM_WIN32__ if( s[i] == '\\' && (i+1) < s.length() && filename != "") // Wait until after parsing a filename before looking for escape sequences #else if( s[i] == '\\' && (i+1) < s.length()) #endif
