generic path for files

Question

Im not sure what it is called but ill do my best to explain it. I did search here on stack exchange and found this answer for an allias for path but i dont want to set a variable for it and i already know that. create alias for path

What I need is and its been along time since I seen it but its used with a % or $ or something that when the program runs from the directory it knows where the directory for the game files are. It didn't matter what the directory the program is in as long as the directory 'gameFiles' is in that directory it will work.

Here's my path:

"/storage/emulated/0/MyGame/MyHackGame/jni/gameFiles/oscom.txt"

I think its something like:

"%or$/gameFiles/oscom.txt"

The main problem is I have a project on source forge and don't want my developers to have to change these paths like 100 times to run the program and then I'll have to change them back.

Also iam using aide for android to make the program and using the standard c++ libaray do this might be difficult to do. I'm not even sure if I can add libarays with aide and native code or how to do it.

What exactly do you want to expand/match the wildcard expression `%or$` to? From you path format I suppose you're addressing unix like filesystem style only, or should that work for windows filesystem pathes as well? — πάντα ῥεῖ, Jul 08 '15 at 18:02
What's a symbolic link it that the name of what I'm trying to do? — Jason Lickliter, Jul 08 '15 at 18:02
I'm working with aide on android but if its possible I'd like to code things to be cross platform? — Jason Lickliter, Jul 08 '15 at 18:05
@JasonLickliter Well, [`boost::filesystem`](http://www.boost.org/doc/libs/1_41_0/libs/filesystem/doc/index.htm) provides some good cross platform approach to deal with file path expressions. Along with using `std::regex` or `boost::regex`, I could well imagine solutions to resolve to a final complete path. — πάντα ῥεῖ, Jul 08 '15 at 18:07
Are you looking for environment variables (https://en.wikipedia.org/wiki/Environment_variable)? You can read them using the `getenv()` function from within a C program. — alk, Jul 08 '15 at 18:08
I got a project on source forge and I don't want other developers having to change say 100 paths to get the program to run and then I'll have to change them back to run it. — Jason Lickliter, Jul 08 '15 at 18:09
@JasonLickliter: Use some constant expression. In C this can easily be achived on code level by `#define MYPATH "/my/random/path/"`. and then code `... = fopen(MYPATH"gameFiles/oscom.txt", ...` — alk, Jul 08 '15 at 18:11
Ok I updated and edited the question to make it more clear. Sorry for that I don't want down votes this time. — Jason Lickliter, Jul 08 '15 at 18:13
You know πάντα ῥεῖ brings up a good point cause isn't windows paths back slashes and not forward slashes? C:\windows\directory? So that's a problem with this running on windows no matter what. — Jason Lickliter, Jul 08 '15 at 18:18
Well I'm not really asking how to add a libaray. I'd rather stick to standard c++ — Jason Lickliter, Jul 08 '15 at 18:20
@JasonLickliter `boost` libraries are designed to be used in cross platform environments (they're even considered as _pre-standard_ proposals sometimes). I don't have any specific experience with android and the aide-ide, but I think it should be possible to integrate it with your code. — πάντα ῥεῖ, Jul 08 '15 at 18:57

Use symlinks as Eugene has suggested or modify build scripts to generate user specific paths into binaries or spearate files at build time. These are ignored by version tracking, so no more double mills. Another way might be checking env variables at runtime.
