elsfv v1.0.0/Style

elsfv verifies file presence and checksums against .sfv/.srr files, reporting on matches, mismatches, and missing files. For .srr files it is additionally possible to extract certain metadata contents to replace mismatched or missing files.

elsfv verifies the first .sfv and first .srr file it finds in the current working directory when no specific .sfv/.srr filename is given.

Windows users can examine the included "rightclick.reg" registry file and install it for an Explorer right click function to check .sfv/.srr files inside a selected directory.

Try:  'elsfv --help'

Note: elsfv is not, strictly speaking, a c64 related tool. This is intentional.

Setting aside the preliminary support for .srr files, did the world really need another .sfv checker? Speed-wise, elsfv is within the ballpark of the faster checkers and could probably improve, but this release was driven mostly by dissatisfaction with the output of every other command line sfv checker we tried. Many do not handle unicode or long file paths under Windows. Some reach failure states under XP which is obsolete but in the circles we run in, remains in use by our fellow retro computing cultists. And then just overall convenience of the CLI.

Consider which output is easier to consume and conveys more information. Output from pdsfv:

Or output from elsfv (which doesn't require passing the .sfv or .srr filename if it can find them in the cwd):

C:\Perturbator-Night_Driving_Avenger_EP-FREEWEB-2012-BandCamp_iNT
> elsfv -v

.sfv failed (1 mismatch; 1 missing; 3 passed out of 5 checked)

And sometimes all you really need is the most concise output regarding the overall pass/fail:

C:\Perturbator-Night_Driving_Avenger_EP-FREEWEB-2012-BandCamp_iNT
> elsfv
verify 00_perturbator-night_driving_avenger_ep-web-2012-bandcamp.sfv
.sfv failed (1 mismatch; 1 missing; 3 passed out of 5 checked)

Finally, when you have both .sfv and .srr:

C:\Radiohead-Spectre-FREEWEB-2015-KPS_INT
> elsfv -v
verify 00-radiohead-spectre-freeweb-2015-kps_int.sfv
 == : 01-radiohead-spectre.mp3
.sfv passed (1 file)

elsfv works the way we think an sfv checker should, but feel free to send feature requests and bug reports!
