# RVerbalExpressions 


[![AppVeyor Build status](https://ci.appveyor.com/api/projects/status/phr93q0rp7edf376?svg=true)](https://ci.appveyor.com/project/tyluRp/rverbalexpressions-4tt0n)
[![CRAN status](https://www.r-pkg.org/badges/version/RVerbalExpressions)](https://CRAN.R-project.org/package=RVerbalExpressions)
[![CRAN_Download_Badge](https://cranlogs.r-pkg.org/badges/RVerbalExpressions)](https://cran.r-project.org/package=RVerbalExpressions)


The goal of `RVerbalExpressions` is to make it easier to construct regular expressions using grammar and functionality inspired by [VerbalExpressions](https://github.com/VerbalExpressions). Usage of `%>%` is encouraged to build expressions in a chain like fashion.

## Installation

Install the released version of `RVerbalExpressions` from [CRAN](https://cran.r-project.org/package=RVerbalExpressions):

```r
install.packages("RVerbalExpressions")
```

Or install the development version from GitHub with:

``` r
# install.packages("devtools")
devtools::install_github("VerbalExpressions/RVerbalExpressions")
```

## Example

This is a basic example which shows you how to build a regular expression:

```{r example, message=FALSE}
library(RVerbalExpressions)

# construct an expression
x <- rx_start_of_line() %>% 
  rx_find('http') %>% 
  rx_maybe('s') %>% 
  rx_find('://') %>% 
  rx_maybe('www.') %>% 
  rx_anything_but(' ') %>% 
  rx_end_of_line()

# print the expression
x

# test for a match
grepl(x, "https://www.google.com")
```
