# diffviewer

[![Codecov test coverage](https://codecov.io/gh/r-lib/diffviewer/branch/main/graph/badge.svg)](https://app.codecov.io/gh/r-lib/diffviewer?branch=main)

[![R-CMD-check](https://github.com/r-lib/diffviewer/actions/workflows/R-CMD-check.yaml/badge.svg)](https://github.com/r-lib/diffviewer/actions/workflows/R-CMD-check.yaml)

diffviewer provides an HTML widget for visually comparing files. It currently wraps three javascript libraries:

* [resemble.js](https://rsmbl.github.io/Resemble.js/) for comparing images.

* [daff.js](https://paulfitz.github.io/daff/) for comparing data frames.

* [jsdiff](https://github.com/kpdecker/jsdiff) for everything else.

It extracts out common UI provided by [shinytest](https://rstudio.github.io/shinytest/index.html) and [vdiffr](https://vdiffr.r-lib.org).

## Installation

You can install the released version of diffviewer from [CRAN](https://CRAN.R-project.org) with:

``` r

install.packages("diffviewer")

```

## Example

This is a basic example which shows you how to solve a common problem:

```{r example, eval = FALSE}

library(diffviewer)

path1 <- tempfile()

writeLines(letters, path1)

path2 <- tempfile()

writeLines(letters[-(10:11)], path2)

visual_diff(path1, path2)

```
