how that's seen in my mind:
having met include, fasm fetches full path of the file then fasm inspects list of files it has included if no such file included, fasm includes it regardless once presence if a file had been included and once present, fasm does nothing |

Sounds like you're having the multiple declaration problem that C headers solve with condition preprocessor macros. Doesn't Fasm have those?

Good job. I like to see small modifications like this.
Can you post just the differences (a patch type file) only? Also, I didn't try it, but can the first instance of a file also use the "once" syntax? That is: do users need to worry about which include statement is the first, or can they just make everything "include once"? |

Just some things I think people should be aware of before they decide to use it:
There is a limit of 254 files plus one pointer that must be kept as zero to terminate the search. Also the path and case must be specified exactly the same else it won't match. Code: include once 'abc.inc' ;... include once 'ABC.INC' ;<--- on Windows this is the same file. ;... include once '.\abc.inc' ;<--- the same file again but not matched. |

It's quite controversial by itself, whether it is a responsibility of the includer or the includee to ensure unique inclusion, or how "include once" should behave in relation to the normal include. And if it doesn't even make use of smth. like GetFileInformationByHandle, it's no better than the existing macros doing the same. In the current implementation it's actually worse. _________________ Faith is a superposition of knowledge and fallacy |

I don't see why it is worse. But anyhow, knowing the limitations should be enough. Users can then decide if it is fit for their purpose(s). Having some sort of coding standard documentation for specifying file paths could help to avoid problems in one's code.

Quote: I don't see why it is worse. There's at least one technical reason (you mentioned) for that: the limit of 254 files. And the conceptual reason is that macros give more flexibility. E.g., if you have a (say "legacy") project using only include, then you can use my includecheck (it can be improved using irpv) to avoid include duplication without having to refactor the project. Quote: Having some sort of coding standard documentation for specifying file paths could help to avoid problems in one's code. And why should one introduce such a limitation for a native solution, if it is (contrary to macros) possible to avoid it? _________________ Faith is a superposition of knowledge and fallacy |
