Provide "quote" inline formatter

[hadley]

• When colour available, colours output, and sets background colour for leading or trailing spaces
• When colour not available, surrounds output in ".

Would want to be able to choose the quote marks and the colour.

It's also interesting to think about whether this should just be standard behaviour for some of the built-in inline styles (e.g. {.fun function_name}, {.file path/to/a/file}) or whether this "color plus no-color fallback" should just be a possible and suggested pattern for custom styles.

[hadley]

Should definitely be the case for paths, since trailing spaces are a definite real problem. Probably less so for function names.

[gaborcsardi]

It is already the standard behavior AFAICT:

❯ x <- " weird "; cli::cli_text("qwe {.path {x}} qwe")
qwe ' weird ' qwe

[jennybc]

Ah, so the quotes surrounding {.file} appear conditionally, if there is leading or trailing whitespace.

I tend to think we want the quotes unconditionally, at least in the NO_COLOR case.

I also have a specific scheme for inline style (color) and quoting that helps to make a very important distinction:

• A Google (spread)Sheet is styled as {.file} and, when NO_COLOR, should be double-quoted
• A (work)sheet is styled as {.field} and, when NO_COLOR, should be single-quoted

It is likely that I should create custom inline styles, give them good names, etc.

Although specific, I think my requirements are relevant to the more general question about the quoting behaviour of the inline formatters.

[gaborcsardi]

I don't think we would want to quote generic <span> tags, that's too aggressive. Quoting newly added tags is pretty easy:

cli_div(theme = list(.sheet = list(before = '"', after = '"')))
sh <- "sheet"
cli_alert_success("this is a {.sheet {sh}} here")

#> v this is a "sheet" here

sh <- "      weird sheet  "
cli_alert_success("this is a {.sheet {sh}} here")

#> v this is a "      weird sheet  " here

I kind of like the background colour idea for paths — it seems like a nice general solution.

[gaborcsardi]

@hadley would you set the background color for the whole path, or just for the leading/trailing spaces?

[hadley]

Just the leading/trailing spaces (to make it obvious that's there's something weird going on with your path).

[jennybc]

I'm still concerned that a file path has no inline styling in the NO_COLOR context (if it's free of leading/trailing whitespace). Indicated by the orange arrow below.

(And yes I'm still thinking about how I want to style spreadsheet and worksheet names, in terms of context.)

I think usually the text indicates that it is a file or package, etc. But I don't mind always adding the quotes, that's fine as well.

[gaborcsardi]

I'll re-open this to always add the quotes, and also to choose a better marker bg: set it to the same color as the foreground.
