4.4.0 now includes "%||%" in base

I've always called it the "null operator", but I'm happy to learn of a better name.

{rmonocypher} is now feature complete! Simple (yet bulletproof) encryption

Core encryption function is

encrypt(mtcars, filename = "secure.rds", key = "my secret key!")

Security/usability feedback welcomed!

Below the surface there's lots going on!

  • Argon2 key derivation
  • RFC8439 "Authenticated Encryption with Additional Data" using ChaCha20 stream cipher + Poly1305 Message Authentication
  • Required random bytes (nonce) sourced from OS CSPRNG

users, if your method for creating tables isn't letting you create retro demo effects then what even is the point?

This is {emphatic} output to an SVG animation played back in the browser with 'scale_colour_gradient2()' and some sine waves doing the effect.

Has anyone ever written a "multi-facetted" package for CRAN?

For example, I have a package that uses the connections API.

I would like the full version available from GitHub and r-universe.

Through clever use of defines and 'if' statements etc, the CRAN version would exclude all forbidden code.

Could this exist in one pkg tarball? Or would the tarballs have to be different?

Are there CRAN-specific ENV vars that can be used to control the inclusion/exclusion of code?

hive: has anyone resubmitted a package to CRAN and been asked to fix their use of SET_TRUELENGTH?

@LukeTierney4 thanks for the info. It was unclear whether the NOTE was a blocker to package updates.

I do recall a checkbox when submitting to CRAN along the lines of "I have checked the CRAN checks and fixed all the errors and warnings and notes(?)".

I am mis-remembering the exact text and extents of the assertion - but that was the gist.

{emphatic} typst support: added!

Good news: It works!

Bad news: I can't work out how to disable text wrapping and/or set overflow in a block to be hidden.

Large tables make 'typst' want to reflow the text which I expressly do NOT want to do.

I've added a 'font_size' option to help deal with this, but being able to control reflow/overflow would be better!

{emphatic} now renders to latex!

Which means that Quart/Rmd rendering to PDF now works!
