A code transformer for use with styler::style_text() — pkgtools_style

This transformer is adapted from https://github.com/gadenbuie/grkstyle It differs in that it will break apart long lines regardless of their initial line breaks to try and fit them into a set width. It does not unbreak lines.

Usage

pkgtools_style_transformer(..., width = 70)

Arguments

width: the max width of the code (excludes indent hence approximate)

Unit tests


# style_text('testthat::expect_equal(iris[1, ], structure(list(Sepal.Length = 5.1, Sepal.Width = 3.5, Petal.Length = 1.4, Petal.Width = 0.2, Species = structure(1L, levels = c("setosa", "versicolor", "virginica"), class = "factor")), row.names = 1L, class = "data.frame"))')
