How to use {cli} to format function name with a `.` properly?-CodePudding

If I have a regular function name, this works fine:

fn_name <- "foo"

cli::cli_li("My fuction is {.fn {fn_name}}")
#> • My fuction is `foo()`

But, if I have a function name with a . as a prefix, this produces undesired output:

cli::cli_li("My fuction is {.fn .{fn_name}}")
#> • My fuction is `` .`foo()` ()``

Desired output:

#> • My fuction is `.foo()`

EDIT:

The more general problem I am trying to solve is to produce the following message:

fn_name <- "foo"

cli::cli_li("Fuction name changed from {.fn {fn_name}} to {.fn .{fn_name}}")
#> • Fuction name changed from `foo()` to `` .`foo()` ()``

Desired output:

#> • Fuction name changed from `foo()` to `.foo()`

Why not use the real function name as the function name?

fn_name <- ".foo"
cli::cli_li("My function is {.fn {fn_name}}")
#> • My function is `.foo()`

CodePudding user response：

Using paste0 you could do:

fn_name <- "foo"
cli::cli_li("Fuction name changed from {.fn {fn_name}} to {.fn {paste0('.', fn_name)}}")
#> • Fuction name changed from `foo()` to `.foo()`
