I created an improved AppVeyor CI config (in the spirit of @haarg's Travis CI toolset) which I've been testing and using for a while and now I'm slowly releasing it into more public use. The supplied AppVeyor config (and related helper tools) is able to test all the way back to Perl v5.8.8.8 (the earliest Strawberry Perl available). Further information about the AppVeyor CI config is available at rivy/CI.AppVeyor.helpers-perl.

Notably, dzil is still a work-in-progress and not very functional on MSWin32. Additionally, dzil is version restricted to perl 5.14+. So, testing falls back to prove for non-build/make, which works just fine for this module.

Since, I'm using your module in my Win32::CommandLine module, I wanted to get it correctly testing and installable for all MSWin32 Strawberry Perl versions. So, I added the above noted improved AppVeyor CI config that I created. After expanding testing, I also added some minor test modifications to make all tests pass back to v5.8.8. This involves some test gating for non-CORE and low version modules (in earlier perl versions, because of using the prove testing fallback which doens't install any prereqs).

I had also added a fix for the known File::Temp failures though I see that you have a commit with a repair on "master". I do think the repair here is improved and has more documentation. But I'm happy to remove it if you'd prefer.

Ultimately, this PR compiles successfully all the way back to Perl v5.8.8.8 for MSWin32/AppVeyor and Perl v5.8 for Travis (see reports at AppVeyor CI and Travis CI). It also includes support for code coverage (see reports at CodeCov and Coveralls).

I hope this is acceptable, and let me know if you'd like any changes.

Hrm, this failed on 5.12 in AppVeyor because perl.exe wasn't found. Strange.

Yeah, I saw that last night and fixed it on "canary".

I traced it to a pl2bat bug in Perl v5.12. Using perl -S prove -bl instead of just prove -bl fixes the problem. Initially, I was just using that for v5.12, but I think it's more robust. So, I'm refactoring all prove uses into perl -S prove.

I hadn't seen it before; pulling in the needed dependencies for testing Text::Template installed a newer prove which triggered the bug.

I'm testing a few repos before I advance "stable".

But, it's passing completely for Text::Template now, see https://ci.appveyor.com/project/rivy/perl-text-template/builds/22505654.

BTW, I'm pulling in a couple of required testing dependencies with the .appveyor_init.BAT file (set "DIST_EXTRA_DEPS=Test::More~0.94 Test::More::UTF8 Test::Warnings"). That will need to change in the future if the module requirements change.

That line (actually, the entire .appveyor_init.BAT) could be removed if replaced with a cpanfile in the repo.

Either one will have to be maintained. But, it works either way... let me know if you want it changed.

I re-pushed an identical PR which does pass all tests (see https://ci.appveyor.com/project/rivy/perl-text-template/builds/22563686).

On your CI, v5.14 failed with a network DNS failure. If you restart the CI testing on your side, it should pass.

Merged. Will release to CPAN in the morning if the builds all check out.

Thanks for the contribution!
