Substring(s) of an ANSI colored string
This is a color-aware counterpart of base::substr().
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_substr(x, start, stop)
x |
Character vector, potentially ANSI styled, or a vector to coarced to character. |
start |
Starting index or indices, recycled to match the length
of |
stop |
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.
