#### What's the license?
|
|
|
|
These libraries are in the public domain (or the equivalent where that is not
|
|
possible). You can do anything you want with them. You have no legal obligation
|
|
to do anything else, although I appreciate attribution.
|
|
|
|
#### <a name="other_libs"></a> Are there other single-file public-domain/open source libraries with minimal dependencies out there?
|
|
|
|
[Yes.](https://github.com/nothings/stb/blob/master/docs/other_libs.md)
|
|
|
|
#### If I wrap an stb library in a new library, does the new library have to be public domain?
|
|
|
|
No.
|
|
|
|
#### Some of these libraries seem redundant to existing open source libraries. Are they better somehow?
|
|
|
|
Generally they're only better in that they're easier to integrate,
|
|
easier to use, and easier to release (single file; good API; no
|
|
attribution requirement). They may be less featureful, slower,
|
|
and/or use more memory. If you're already using an equivalent
|
|
library, there's probably no good reason to switch.
|
|
|
|
###### Can I link directly to the table of stb libraries?
|
|
|
|
You can use [this URL](https://github.com/nothings/stb#stb_libs) to link directly to that list.
|
|
|
|
#### Why do you list "lines of code"? It's a terrible metric.
|
|
|
|
Just to give you some idea of the internal complexity of the library,
|
|
to help you manage your expectations, or to let you know what you're
|
|
getting into. While not all the libraries are written in the same
|
|
style, they're certainly similar styles, and so comparisons between
|
|
the libraries are probably still meaningful.
|
|
|
|
Note though that the lines do include both the implementation, the
|
|
part that corresponds to a header file, and the documentation.
|
|
|
|
#### Why single-file headers?
|
|
|
|
Windows doesn't have standard directories where libraries
|
|
live. That makes deploying libraries in Windows a lot more
|
|
painful than open source developers on Unix-derivates generally
|
|
realize. (It also makes library dependencies a lot worse in Windows.)
|
|
|
|
There's also a common problem in Windows where a library was built
|
|
against a different version of the runtime library, which causes
|
|
link conflicts and confusion. Shipping the libs as headers means
|
|
you normally just compile them straight into your project without
|
|
making libraries, thus sidestepping that problem.
|
|
|
|
Making them a single file makes it very easy to just
|
|
drop them into a project that needs them. (Of course you can
|
|
still put them in a proper shared library tree if you want.)
|
|
|
|
Why not two files, one a header and one an implementation?
|
|
The difference between 10 files and 9 files is not a big deal,
|
|
but the difference between 2 files and 1 file is a big deal.
|
|
You don't need to zip or tar the files up, you don't have to
|
|
remember to attach *two* files, etc.
|
|
|
|
#### Why "stb"? Is this something to do with Set-Top Boxes?
|
|
|
|
No, they are just the initials for my name, Sean T. Barrett.
|
|
This was not chosen out of egomania, but as a moderately sane
|
|
way of namespacing the filenames and source function names.
|
|
|
|
#### Will you add more image types to stb_image.h?
|
|
|
|
If people submit them, I generally add them, but the goal of stb_image
|
|
is less for applications like image viewer apps (which need to support
|
|
every type of image under the sun) and more for things like games which
|
|
can choose what images to use, so I may decline to add them if they're
|
|
too rare or if the size of implementation vs. apparent benefit is too low.
|
|
|
|
#### Do you have any advice on how to create my own single-file library?
|
|
|
|
Yes. https://github.com/nothings/stb/blob/master/docs/stb_howto.txt
|
|
|
|
#### Why public domain?
|
|
|
|
I prefer it over GPL, LGPL, BSD, zlib, etc. for many reasons.
|
|
Some of them are listed here:
|
|
https://github.com/nothings/stb/blob/master/docs/why_public_domain.md
|
|
|
|
#### Why C?
|
|
|
|
Primarily, because I use C, not C++. But it does also make it easier
|
|
for other people to use them from other languages.
|
|
|
|
#### Why not C99? stdint.h, declare-anywhere, etc.
|
|
|
|
I still use MSVC 6 (1998) as my IDE because it has better human factors
|
|
for me than later versions of MSVC.
