Fast blog deployment, alternative to rsync and scp. I use this to deploy my Hugo blog files. It can be used for any operation that needs to push the contents of a directory to a remote server.
Requires: Rust, Linux x86-64. sshd on the remote server, with working keys and known_hosts already done.
Build: ./build.sh
Usage: de <src> <remote>.
This is how I deploy, from the root of my Hugo directory:
de public my_server:/var/www/blog/ --dry-run
Then again without --dry-run to do it for real.
It uploads a very small helper binary (seed, because Demeter) which calculates a CRC32 of all the files. Then it uploads the new and modified ones, and deletes the removed ones.
The original seed helper was in assembler. I kept it for posterity in archived_asm/. The Rust version is in seed/ and compiles to the same size! See A very small Rust binary indeed for how it's done.
