# styler 1.0.2 (2018-06-10)

This is a maintenance release without any breaking API changes.

## Major Changes

* Fixed indention for named multi-line function calls (#372).
* Non-R code chunks in `.Rmd` files are now respected and won't get styled 
  (#386).

## Minor Changes

* Fixing an edge case in which, if very long strings were present in the code, 
  tokens could be replaced with wrong text (#384).
* Spacing around tilde in formulas depends now on whether there is a LHS 
  in the formula (#379).
* Spaces are now also added around `EQ_SUB` (`=`) (#380).
* Added `CONTRIBUTING.md` to outline guidelines for contributing to styler.
* More informative error messages for parsing problems (#401, #400).
* Improved documentation (#387).

# styler 1.0.1 (2018-03-02)

This is a maintenance release without any breaking API changes.

## Major & dependency related changes

* Removed implicit `dplyr` dependency via `purrr:::map_dfr()` (thanks 
  @jimhester, #324).
* Added required minimal version dependency for purr (`>= 0.2.3`) (#338).
* We rely on the tibble package which was optimized for speed in `v1.4.2` so 
  styler should run ~2x as fast 
  [(#348)](https://github.com/tidyverse/tibble/pull/348). For that reason, 
  styler now depends on `tibble >= 1.4.2`.
* In the dependency `enc`, a bug was fixed that removed/changed non-ASCII 
  characters. Hence, styler now depends on `enc >= 0.2` (#348).

## Minor changes

* We're now recognizing and respecting more DSLs used in R comments: rplumber 
  (`#*`, #306), shebang `#/!` (#345), knitr chunk headers for spinning (`#+` / 
  `#-`, #362).
* Named arguments can stay on the first line if call is multi-line (#318).
* No space anymore with `tidyverse_style()` after `!!` since with `rlang 0.2`, 
  `!!` now binds tighter (#322), spacing around `~` (#316), no space anymore 
  around `^` (#308).
* Code chunks in Rmd documents that don't use the R engine are no longer 
  formatted (#313).
* Various bug fixes and edge case improvements.

# styler 1.0.0 (2017-12-05)

Initial release.

## stylers
These are functions used to style code. They style a directory, a whole package,
a file or a string.
```
style_dir(path = ".", 
  ..., style = tidyverse_style, transformers = style(...), 
  filetype = "R", recursive = TRUE, exclude_files = NULL
)

style_pkg(pkg = ".", 
  ..., style = tidyverse_style, transformers = style(...), filetype = "R", 
  exclude_files = "R/RcppExports.R"
)


style_file(path, 
  ..., style = tidyverse_style, transformers = style(...)
)

style_text(text, ..., style = tidyverse_style, transformers = style(...))
```

## style guides
These functions are the style guides implemented.
```
tidyverse_style(
  scope = "tokens", 
  strict = TRUE, 
  indent_by = 2, 
  start_comments_with_one_space = FALSE, 
  reindention = tidyverse_reindention(), 
  math_token_spacing = tidyverse_math_token_spacing()
)
tidyverse_reindention()
tidyverse_math_token_spacing())
```

## style guide creators
This function is used to create a style guide.
```
create_style_guide(
  initialize = default_style_guide_attributes, 
  line_break = NULL, 
  space = NULL, 
  token = NULL, 
  indention = NULL, 
  use_raw_indention = FALSE, 
  reindention = tidyverse_reindention()
)
```

## Helpers
These are helper functions used to specify the style guides in use.

```
specify_math_token_spacing(
  zero = NULL, 
  one = c("'+'", "'-'", "'*'", "'/'", "'^'")
)

specify_reindention(
  regex_pattern = NULL, 
  indention = 0, 
  comments_only = TRUE
)
initialize_default_attributes(pd_flat)
```
