Substring(s) of an ANSI colored string
This is the color-aware counterpart of base::substring().
It works exactly like the original, but keeps the colors in the
substrings. The ANSI escape sequences are ignored when
calculating the positions within the string.
col_substring(text, first, last = 1000000L)
text |
Character vector, potentially ANSI styled, or a vector to
coarced to character. It is recycled to the longest of |
first |
Starting index or indices, recycled to match the length
of |
last |
Ending index or indices, recycled to match the length
of |
Character vector of the same length as x, containing
the requested substrings. ANSI styles are retained.

str2 <- "another " %+%
red("multi-", sep = "", underline("style")) %+%
" text"
cat(str2, "\n")
cat(col_substring(str2, c(3,5), c(7, 18)), sep = "\n")
substring(strip_style(str2), c(3,5), c(7, 18))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
