# commafree

{commafree} is an R package that provides the "comma-free call" operator:

`%(%`. Use it to call a function with arguments, but without commas

separating the arguments. Just replace the `(` with `%(%` in a function

call, supply your arguments as standard R expressions enclosed by `{ }` and

be free of commas (for that call).

It is especially useful for long multi-line function calls with many

arguments, like a shiny UI definition, an R6 class definition, or

similar.

`%(%` merely does a syntax transformation, so that a call like this:

``` r

func %(% {

  a

  b

  c

}

```

is equivalent to writing this:

``` r

func(

  a,

  b,

  c

)

```

## Installation

You can install {commafree} like so:

``` r

install.packages("commafree")

## Install the dev version:

# remotes::install_github("t-kalinowski/commafree")

```

## Example

``` r

library(commafree)

writeLines(c %(% {

  "I write, erase, rewrite"

  "Erase again, and then"

  "A poppy blooms."

})

```

    I write, erase, rewrite

    Erase again, and then

    A poppy blooms.
