This is a much simplified version of dupver that uses a local repository and file-level deduplication. There are only three commands commit, log, and checkout.

This has been moved to its own repo: https://github.com/akbarnes/gover

To build:

go mod init goutils
go get github.com/bmatcuk/doublestar/v4
go install gover.go

The -msg or -m message flag is optional, as is the -commit or -ci flag as commiting is the default action gover -commit -msg 'a message' file1 file2 file3 gover -ci -msg 'a message' file1 file2 file3 gover -m 'a message 'file1 file2 file3 gover file1 file2 file3

This takes the optional -json or -j argument to output json for use with object shells. To list all the snapshots: gover -log gover -json -log gover -j -log gover -l

To list the files in a particular snapshot: gover -log snapshot_time gover -log -json snapshot_time

This takes an optional argument to specify an output folder. To checkout a snapshot: gover -checkout snapshot_time gover -co snapshot_time gover -out output_folder -co snapshot_time gover -o output_folder -co snapshot_time

Simple program to diff two files. I wrote this to have consistent diff behavior across operating systems. Usage:

godiff file1 file2

It will return equal if the files are equal and different otherwise. If the -errors flag is enabled it will return error if one file does not exist or is unreadable and different otherwise.

If the json flag is enabled it will return false if the files are equal and true otherwise. If the -errors flag is also enabled it will return null if one file does not exist or is unreadable and true otherwise.

Finally, if the -human flag is enabled this will toggle verbose human-readable output which includes automatically reporting if there was an error reading files.
