regexplain

WORK IN PROGRESS!!

regexplain is going to be an RStudio addin that helps you interactively build up your regex. Inspired by RegExr and stringr::str_view.

Done (ish)

You can use view_regex() for a stringr::str_view() replacement that includes groups.

text <- c("breakfast=eggs;lunch=pizza",
          "breakfast=bacon;lunch=spaghetti", 
          "no food here")
pattern <- "((\\w+)=)(\\w+).+(ch=s?p)"

view_regex(text, pattern)

Example view_regex(text, pattern). — Example `view_regex(text, pattern)`.

t_nested <- "anestedgroupwithingroupexample"
r_nested <- "(a(nested)(group(within(group))(example)))"
view_regex(t_nested, r_nested)

Planned (ish)

An Rstudio addin gadget that allows you to interactively enter the regex and see the results. Like the above example, where the regex field is a text input.
Import data from your environment, like a character vector, file, or data.frame column when opening the gadget.
Help tab in the gadget, pulling from ?regex but with some navigation.
Tab to interactively explore output of varying regex-applying functions. In other words, see what stringr::str_locate_all or stringr::str_match_all or grep or grepl return when applying the regex to your text.
