comments in TDF files, but HTTP contains // - howzit work?

Pxtl · Post by **Pxtl** » 30 Jun 2006, 07:42

I'm making a parser for all the TDF and FBI files in a mod to do some automation, but I'm confused about one thing: modinfo.tdf contains an URL field. Since most URLs are written HTTP://www.foo.bar.baz.com, isn't the // turning it into a comment and thus turning

URL=http://ta-aa.sourceforge.net;
ModType=1;

into

URL=http:ModType=1;

after the comment preprocessor is through?

Hm you'd have to try.
Maybe comments are ignored before closing semicolon...

woudltn that turn out as

URL=http:
ModType=1;

Which would generate a boost::spirit parse error? It does that in the TDFParser clas sI ported to NTai, as lindir had a few mistakes such as that......

Stupid Tim Berners-Lee... why must you have made life so difficult for C programmers...

Depends on 3 things: is the linebreak removed as part of the comment?... is the second equality used? Can values span multiple lines? I coded my own parser in C#, and there I only pay attention to the first '=' sign, so the value of URL becomes

Code: Select all

http:ModType=1;

or

Code: Select all

http:
ModType=1;

if you don't strip the linebreak.

which is perfectly allowed by the parser, although very stupid. If the modtype tag is not required, it would explain why it lets you get away with it. I really should just look at the source, but that sounds like work.

If there's any chance the URL line might cause some sort of problem, even on an obscure setup, I guess I should probably cut it. It's not like it's actually used by anything right now.

After alot of struggle with it in my mod Editor for Spring, i managed to make a file parser that i was very happy with.

I too ran into that same problem with a line in the mod XTA. All that was needed was to remove the ability for // comments to be everywhere.

In fact i think it could be one of the major advantages of my program because the file parser was so forgiving, that you could use comments /**/ wherever and completely disregarded {} (which, at the present format of the data are irrelevant anyway). That way, people who were having problems like:

Code: Select all

HP= 500;

(notice the space after "=")
or a missing bracket, could use my program to import the mod and export it with the electronical assurance of a perfect syntax.

If you understand C# and want to check it, i can give you a hint on what files and classes to look at and give you some quick hints on how it works.

I ran into the exact same problem. All i did was look for a : before the //. if there was a :, its a URL, and leave it in. if there wasnt, its a comment, so strip it out. Simple.

My suggestion to make everyones lives easier, make strings have "" around them. then all these problems are solved.

Isn't there a C++ Command symbol that forces C++ used symbols to render as normal symbols? I remember using it for other stuff... maby I'm just crazy.

The problem here is that

armcom=command.txt;

In C++ you would have

armcom="commander.txt" but there're no quotes here. C++ doesnt count // as comments if it's inside quotes

for the parser i suppose it could be solved like in java strings. for instance \n means new line in a java string, so if you actually want to print \ and n, you do \\ because \\ means \

"moo\n" = moo then a new line
"\\" = the character \
"\t" = tab

would make it something like http:\/\/site.com ... yuck never mind :D

lol a 1337 W!

yeah, I'm pretty sure Java and C++ have the same escape commands (\\=\, \n=newline, \a=beep(alert), etc.)

although... i don't really know much about Java...

as far as i know, most programming languages have that. C, PHP, Java, Javascript, everything i can think of except VB has it.
