How to type curly bracket { in the glue content

[JiaxiangBU]

library(glue)
glue("@online{Li2019,")
#> Error in glue_data(.x = NULL, ..., .sep = .sep, .envir = .envir, .open = .open, : Expecting '}'

Temporally,

library(glue)
library(rebus)
library(tidyverse)
open <- '{'
glue("@online{open}Li2019,") %>% 
    cat
#> @online{Li2019,

I don't think it is an effcient way.

You can change the opening delimiter by .open.

glue::glue("@online{Li2019,", .open = "{{")
#> @online{Li2019,

@yutannihilation Hi, thanks for your quick reply. It works for me by customing the open and close delimiters.

add_text <- 123
glue::glue("@online{Li2019,", .open = "{{")
#> @online{Li2019,
glue::glue("@online{Li20190{{add_text}},", .open = "{{")
#> @online{Li20190123},
glue::glue("@online{Li2019-{add_text},", .open = "{{")
#> @online{Li2019-{add_text},

For the closing delimiter use .close
