And I really want to have this in fasm2 project, it's an invaluable addition there.

Hi,
'?' preffix prepended to identifier seems to be causing problems to fasmg when using number modifier.... running for some time then exiting with exit code -1073741819 Code: calminstruction test_num? arg& local _arg arrange _arg, arg stringify _arg match arg=number, arg, = jno @fail display _arg bappend ' is a litteral number' bappend 0x0A0D exit @fail: display _arg bappend ' is NOT a litteral number' bappend 0x0A0D end calminstruction test_num ?dummy |

Hi Tomasz,
the new match /modifier feature is really nice.. helping to greatly simplify code, where advanced parsing is needed.. however, i have a small issue, illustrated by below snippet Code: calminstruction test arg*& local _name, _tail match _name:name _tail?, arg, : jno @err_invalid_name arrange _name, _name.=suffix stringify _name display 'suffixed name: ' bappend _name bappend 0x0A0D exit @err_invalid_name: stringify arg err 'invalid identifier / name specif. -> ' bappend arg bappend 0x0A0D end calminstruction test dummy = 1 ... which gives below output : Quote:
=> note the space after identifier 'dummy' in 'dummy .suffix' - where i would have expected 'dummy.suffix' => is this intended ? am i missing sthg ? can u pls have a look tx |

Yes, I'm aware of that issue, I was hoping it would not be a big deal. It's a limitation of the engine that causes the trailing whitespace to be consumed when parsing an identifier. This was never a problem when fasmg was only using it internally, because identifier was always interpreted as already complete pointer to a symbol, but once you try to append anything, like in your example, the redundant whitespace causes trouble.
Unfortunately, this limitation is integral to the old core of fasmg's engine, so the only workaround I can offer is to strip the whitespace afterwards with just a regular wildcard matching: Code: match _name:name _tail?, arg, : jno @err_invalid_name match _name,_name ; this strips the whitespace |
