| Summary | 0025171: Data Exchange, STEP Lexer - the strings with quote sign inside can't be properly lexed | ||||
| Description | In my case, I had a file generated by PRO/ENGINEER with some french words used as strings. Example: DESCRIPTIVE_REPRESENTATION_ITEM('MATIERE', 'Fil d'acier'); The current STEP lexer can't properly handle this situation and the application refuses to parse a file at all. | ||||

Unfortunately, here I can't provide a straight-forward fix to the problem. As a temporary fix on my side I use the modified lex.step.c file, which normally generated by flex from step.lex file. Since, I'm not that familiar with flex syntax, I would prefer somebody else to fix the original source file. While the modified lex.step.c I've attached to this ticket (all modification are marked with 0025171 string - 5 modifications in total) |

lex.step.c (50,704 bytes) |
|
|
Please, check the provided modifications and fix the original source file. |
|
|
The problem is that the regular expression for the text arguments (described in step.lex) does not pass the single apostrophe - ' in the text. Current regexp for the text arguments: [\']([\n]|[\000\011-\046\050-\176\201-\237\240-\777]|[\047][\047])*[\'] |
