Unicode Symbols at the R Prompt

A small subset of Unicode symbols, that are useful when building command line applications. They fall back to alternatives on terminals that do not support Unicode. Many symbols were taken from the 'figures' 'npm' package (see < https://github.com/sindresorhus/figures>).

Inspired by (and mostly copied from) the figures JavaScript project.

Install

install.packages("devtools")
devtools::install_github("gaborcsardi/clisymbols")

Usage

library(clisymbols)
cat(symbol$tick, "All good\n")

#> ✔ All good

cat(symbol$cross, "Problem\n")

#> ✖ Problem

Here is a list of all symbols, with their names:

for (i in seq_along(symbol)) {
  cat(symbol[[i]], "\t", names(symbol)[i], "\n", sep = "")
}

Fallback symbols

Some terminals do not support (all) Unicode characters, and on these reasonable ASCII substitutes are used:

#> √   tick
#> x   cross
#> *   star
#> █   square
#> [ ] square_small
#> [█] square_small_filled
#> ( ) circle
#> (*) circle_filled
#> ( ) circle_dotted
#> (o) circle_double
#> (o) circle_circle
#> (x) circle_cross
#> (|) circle_pipe
#> (?) circle_question_mark
#> *   bullet
#> .   dot
#> ─   line
#> =   double_line
#> ... ellipsis
#> >   pointer
#> i   info
#> ‼   warning
#> ≡   menu
#> ☺   smiley
#> ┌─┐ mustache
#> ♥   heart
#> ^   arrow_up
#> v   arrow_down
#> <   arrow_left
#> >   arrow_right
#> (*) radio_on
#> ( ) radio_off
#> [x] checkbox_on
#> [ ] checkbox_off
#> (x) checkbox_circle_on
#> ( ) checkbox_circle_off
#> (?) fancy_question_mark
#> !=  neq
#> >=  geq
