Better formatting

[numero-744]

@Dolu1990 convinced me that even if SpinalHDL enables the user to abstract the wires, sometimes the user wants to manipulate wire-by-wire so aligning stuff would be great.

In https://github.com/numero-744/Aes there is a repository fully auto-formatted using scalafmt, with alignments (=, :=, #= and port), using port syntax for better rendering.

Also, I have added a few idioms as VSCode snippets, I wrote the full snippets as comments in the files where I would use them, but don't forget it is even shorter with auto-formatting 😉

See the readme of the repository for more information.

I'll open a PR to merge some stuff from that repository once Spinal 1.8 has been released with the port notation. Before that, comments appreciated 😃

PS: We could also merge some stuff in SpinalHDL itself?

Related to the AES ?

There is also https://github.com/SpinalHDL/SpinalCrypto

So i don't know what is better. As crypto is a realy realy realy large field, maybe it is better to keep things in standalone libraries ?

Related to the AES ?

No, it was mainly about the scalafmt configuration.

The AES itself is just for demo, it is inspired from school work (initially done in VHDL at school with a different structure).

I only use it as a demo for SpinalHDL stuff to demonstrate features:

• With SpinalHDL I can express things the way I think them, with short-but-expressive code.
• It has useful libraries such as FSM
• Here I added snippets / idioms I suggest
• It has really nice auto-formatting

I don't want to merge this AES into anything ^^'

FYI while working on SpinalHDL/SpinalHDL#161 I've added -> alignment on the AES repository, see the test file: numero-744/Aes/hw/spinal/aes/Rcons.scala.

Ahhh sure ^^

FYI while working on SpinalHDL/SpinalHDL#161 I've added -> alignment on the AES repository, see the test file: numero-744/Aes/hw/spinal/aes/Rcons.scala.

Hmm one question is :
Is that alignement forced by the formating tool ? or allowed by it ?

[numero-744]

Alignments are performed by scalafmt, but formatting can be locally disabled, for instance: https://github.com/numero-744/Aes/blob/main/hw/spinal/aes/SBox.scala#L28
