Highlight text within an R object which matches a given regex. This only works in a terminal which supports ANSI colour codes.
There are slightly different versions of the highlighting function depending upon which text version of the object you'd like to match against:
- the given object x must already be a character string
- performs the matching after first calling
as.character(x)
- performs the matching against the default
print(x) output
- performs the matching after first calling
deparse1(x)
- performs the matching on the output of calling
str(x)
hl_grep(x, pattern, fg = "black", bg = "yellow", ..., perl = TRUE)
hl_grep_character(x, pattern, fg = "black", bg = "yellow", ...)
hl_grep_print(x, pattern, fg = "black", bg = "yellow", ...)
hl_grep_deparse(x, pattern, fg = "black", bg = "yellow", ...)
hl_grep_str(x, pattern, fg = "black", bg = "yellow", ...)character string
regular expression string. Note: don't get too fancy here
any valid R colour specification e.g. 'hotpink', '#335588'
extra args passed to gsub
