cli R package progress bars not showing through progressr handler

[rafev]

I am having an issue where my progress bar no longer shows. I use the progressr package and use handler("cli") to display the progress bar as a CLI version for the ETA output. This worked perfectly under R v4.2.1 on my M1 mac, but now on v4.3 it does not display at all. Other progress handlers work, except for the CLI version, so I assume it's this version. Any clue what's happening?

handlers(global = TRUE)
handlers("cli")

my_1way.mods = function(modules_being_tested) {
    p = progressor(along = modules_being_tested)
    foreach (i = modules_being_tested) %dopar% {
        # Run GLMNET
        set.seed(32)
        Net.fit = train(x = train_grp[, module_df[module_df$colors == i, 1]],
                        y = train_pheno,
                        method = "glmnet",
                        trControl = cctrl1,
                        metric = "RMSE",
                        tuneGrid = expand.grid(.alpha = seq(.05, 1, length = 15),
                                               .lambda = seq(0.01, 1, 0.005)))

            p(sprintf("i=%s", i))

        my_list[[i]] = Net.fit
    }
}

I just checked, the following example from https://progressr.futureverse.org/ still works:

$ R --quiet --vanilla

> library(progressr)
> handlers(global = TRUE)
> handlers("cli")

> slow_sum(1:10, message = FALSE)
[1] 55
>

i.e. it produces a green cli progress in the terminal. I recommend that you start by making sure that works.

Thank you. Confirmed to work on my end as well after a laptop reboot, oddly enough.
