Similar to .PKGINFO, .SRCINFO provides structured metadata from the PKGBUILD to be included with source packages. The format is structured such that it contains a "pkgbase" and one to many "pkgname" sections. Each "pkgname" section represents an "output package", and inherits all of the attributes of the "pkgbase" section, and then can define their own additive fields. For example, a simple PKGBUILD: pkgbase=ponies pkgname=('applejack' 'pinkiepie') pkgver=1.2.3 pkgrel=1 arch=('x86_64' 'i686') depends=('friendship' 'magic') build() { ...; } package_applejack() { provides=('courage') ...; } package_pinkiepie() { provides=('laughter') ...; } Would yield the following .SRCINFO file: pkgbase = ponies pkgdesc = friendship is magic pkgver = 1.2.3 pkgrel = 1 arch = x86_64 arch = i686 depends = friendship depends = magic pkgname = applejack provides = courage pkgname = pinkiepie provides = laughter The code to generate this new file is taken a project which I've been incubating[0] under the guise of 'mkaurball', which creates .AURINFO files for the AUR. AURINFO is the exactly same file as .SRCINFO, but named as such to make it clear that this is specific to the AUR. Because we're parsing shell in the packaging functions rather than executing it, there *are* some limitations, but these only really crop up in more "exotic" PKGBUILDs. Smoketesting[1] for accuracy in the Arch repos yields 100% accuracy for [core] and [extra]. [community] clocks in at ~98% accuracy (.3% difference per PKGBUILD), largely due to silly haskell packages calling pacman from inside the PKGBUILD to determine dependencies. [multilib] currently shows about 92% accuracy -- a statistic which can be largely improved by utilizing the recently merged arch-specific attribute work. This is also a smaller repo so the numbers are somewhat inflated. In reality, this is only a .8% variance per PKGBUILD. Together, we can make PKGBUILD better.
