Re: [racket-users] Automated method for making racket package installs consistent?

[Sam Tobin-Hochstadt]

The list of explicitly-installed packages is available from `raco pkg
show`. You could use a script to parse that, or you can use
`installed-pkg-table` from `pkg/lib` to get the list in Racket.

Re: [racket-users] Automated method for making racket package installs consistent?

[schle...@gmail.com]

This is just a suggestion, that does not help with your current dilemma, a 
strategy how you could prevent it in the future:

Create or expand your personal dotfile repository, within that repository 
create a folder my-racket-packages, within that folder create a info.rkt:
#lang info
(define collection "my-racket-packages")
(define deps
  (list "lens"
"opengl"
"gregor"
"add your own packages here"))

This way you can create a personal package that lists all of the packages 
that you play around with explicitly.
https://docs.racket-lang.org/pkg/metadata.html
You can then just use drracket or raco to install that package locally.
Within the directory:
raco pkg install

to install the package.
When the dotfiles have changed, within the my-racket-packages directory:
raco pkg update --auto

I know this solution requires you to update the package manually, but if 
you install a package via raco pkg install , you might as 
well add it to the info.rkt instead.
This way you have a single source of truth, instead of having to sync 
multiple different installations.

Instead of my-racket-packages you also could name it my-racket-experiments 
and save your experiment sessions with scripts along with the dependencies.
You never have to publish that package if you don't want to.

Re: [racket-users] [DrRacket] Is there a way to go to last edit location?

[Laurent]

I couldn't find an easy way to do this. (As a hack, I even tried undo+redo,
but this also includes cursor movements apparently, so it doesn't help.)

AFAICT, the undo history is buried under several private layers, so it's
inaccessible from `send` (and thus currently not accessible from
Quickscript), but a plugin may do. Augmenting `on-insert`:
https://docs.racket-lang.org/gui/text_.html?q=on-insert#%28meth._%28%28%28lib._mred%2Fmain..rkt%29._text~25%29._on-insert%29%29
to record the last insert position should work.
