Truncating silently markup in RStudio when string ends with markup.

[olivroy]

Edit: RStudio issue fixed in 2023.12.0 version

Possibly the string widths are not correctly assessed?,

Output of my RStudio console

Expected (works when cli.width >= 68.) i.e. if your console width is wider than 68 when not setting options.

because it seems to work as expected in the reprex

to_print <- "A long {.val value} with a {.href [link](https://github.com)} with other stuff like {.help cli::inline-markup}"
options(cli.width = 35)
cli::cli_bullets(to_print)
#> A long "value" with a link
#> (<https://github.com>) with other
#> stuff like `?cli::inline-markup()`

^{Created on 2023-08-30 with reprex v2.0.2}

Related to #578, because I first encountered this behaviour at startup, but this seems like a different issue.

Note: I used options(cli.width) here for reproducibility purpose only, but I am trying to recreate the behavior when not setting options.

Let me know if I can provide more info. (I am still on an older RStudio version 2023.06.1, but I don't think this has been changed recently.)

• This seems related to console width, because when the console is wide enough, this doesn't seem to occur.

Oh! I just discovered something else: the bug occurs in some situations, but having inline markup at the end of the string seems to be more problematic.

# This works as expected
to_print <- "A long {.val value} with a {.href [link](https://github.com)} with other stuff like {.help cli::inline-markup} is okay."

Once the end of string inline markup bug is fixed, I can see if silent truncation comes up in other situations.

I can circumvent this by setting options(cli.width = Inf), but this is not ideal as it can other have undesired effects.

@gaborcsardi I tried creating a failing test for that, but could not see what was wrong. I am only able to reproduce in RStudio interactively.

I tried the following. but the snapshot looks fine, but does not reflect the interactive behavior.

  expect_snapshot({
    withr::local_envvar(
      R_CLI_HYPERLINKS = "true",
      R_CLI_HYPERLINK_RUN = "true"
    )
    rlang::local_interactive()
    withr::local_options(cli.unicode = TRUE)
    withr::local_options(cli.num.color = 256L)
    withr::local_options(cli.width = 25)
    cli_text("A {.val veryaaaaa} long hyperlink {.href [text](https://github.com)}")
  }

  )

Edit: this problem has more impact than I thought also. It seemed to interfere in a styler warning that I saw yesterday. maybe related to #562?

Hi @gaborcsardi, do you think this is a cli or RStudio issue? Do you think it will be fixed by rstudio/rstudio#13869. If so, maybe mention it for QA.

[gaborcsardi]

Does it happen outside of RStudio? E.g. in a (non-RStudio) terminal?

[olivroy]

Doesn't seem like it. (although I don't have a terminal that supports links)

Are you able to see this behavior with this reprex in a terminal? (the word value doesn't appear)

to_print <- "A long {.val value} with a {.href [link](https://github.com)} with other stuff like {.help cli::inline-markup}"
options(cli.width = 35)
cli::cli_bullets(to_print)

[gaborcsardi]

It works in a terminal. It is probably this issue: #560, already reported to RStudio.
