view_regex: View grouped regex results

In gadenbuie/regexhelp: Rstudio Addin to Explain, Test and Build Regular Expressions

Description

View the result of the regular expression when applied to the given text. The default behavior renders the result as HTML and opens the file in the RStudio viewer pane. If render is FALSE, the HTML itself is returned. If the output is destined for a knitr document, set knitr to TRUE.

Usage

view_regex(
  text,
  pattern,
  ...,
  render = TRUE,
  escape = render,
  exact = escape,
  result_only = FALSE
)

Arguments

text	Text to search
pattern	Regex pattern to look for
...	Arguments passed on to base::regexec ignore.case if FALSE, the pattern matching is case sensitive and if TRUE, case is ignored during matching. perl logical. Should Perl-compatible regexps be used? fixed logical. If TRUE, pattern is a string to be matched as is. Overrides all conflicting arguments. useBytes logical. If TRUE the matching is done byte-by-byte rather than character-by-character. See ‘Details’.
render	Render results as HTML?
escape	Escape HTML-related characters in text?
exact	Should the regex pattern be displayed as entered by the user into R console or source (default)? When TRUE, regex is displayed with the double \\\\ required for escaping backslashes in R. When FALSE, regex is displayed as interpreted by the regex engine (i.e. double \\\\ as a single \\).
result_only	Should only the result be displayed? If FALSE, then the colorized regular expression is also displayed in the output.

Examples

view_regex("example", "amp", render = FALSE)
