Hello I am progressing with my use of SmaCC and I think a found the source of the problem that makes it impossible to generete the classes for the parser and scanner.
Scenario 1) I gave the name for both classes: the parser and the scanner. 2) I copy the very simple first part of the tutorial 3) I clicked on the Compile LR(1) button and a window popped up with the label: "Both classes are not specified" Problem: At the time the method SmaCCDevelopmentUI>>compile: was invoked the expression self parserClassString returns an empty string (although I entered the name of a class on the UI) I found that the "parserClassMorph" did not hold the name of the class Then I breakpointed the method SmaCCDevelopmentUI>>addParseClass: and I entered a new name for the class of my parser and I follow with the debugger the execution that follows the invocation of the method. Everything works as expected. I changed the name again but the method SmaCCDevelopmentUI>>addParseClass: (the one with a breakpoint) was not called again. I think it is a problem related to Morph . I am a complete ignorant on Morph (among other things) so it is hard for me to fix the problem. I hope this message helps fix the issue Federico -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
