Version flag
Would it it be possible and useful for others than just me to add a version flag? I wrote this little wrapper to manage compressions : github.com/romainmenke/simple-guetzli
It keeps a log of past compressions to make it work nicely with a watch folder. I thought it would be interesting to optionally recompress all images if a new version is released. To achieve this it would be awesome if there was a version flag.
I second this. It would be useful for the above use-case, and for other utilities and wrappers for guetzli.
It would also make guetzli conform a little better to expected POSIX behaviour. The --version and --help flags are nearly ubiquitous and including them is good practice.
When would you envision the version to increase? Only when a significant number of images will produce different output of on such releases as 1.0.1 too?
Current Releases already follow semantic versioning. I did not mean to question the logic behind the current versioning. I only suggested adding a flag that would return the currently installed version.
A flag like this would also be useful to determine which version of guetzli is installed if/when CUDA/GPU processing (#44) is introduced.
IMHO the actual version should not change unless the actual codebase changes significantly. In order to be able to identify the algorithm state and optimizations you can append the commit the build is based on.
ie guetzli 0.2.1 - c03e7261a5944b0b65043c0bb8b16c52b9329917
This way you can always build on a previous commit to get older algorithm versions and it can be tracked.
@gpant I agree with you on the logic behind the versioning but that is besides the point. I opened this issue not to discus when to bump the version but to request adding a cli flag.
You can open another issue to discus versioning itself.
