Note removing line breaks, always take care comments, since don’t want: become: easiest way taking care applying rule comment token interest, can checked within transformer function. transformer function tidyverse style removes line breaks round closing bracket comes curly brace looks follows: example function set_line_break_before_curly_opening() don’t need worry adding line breaks, don’t remove .","code":"add_one <- function(x) { x + 1 } add_one <- function(x) { x + 1 } code <- c(\"add_one <- function(x) { x + 1 }\") styler:::create_tree(code) ## levelName ## 1 ROOT (token: short_text [lag_newlines/spaces] {id}) ## 2 °--expr: [0/0] {23} ## 3 ¦--expr: [0/1] {3} ## 4 ¦ °--SYMBOL: add_o [0/0] {1} ## 5 ¦--LEFT_ASSIGN: <- [0/1] {2} ## 6 °--expr: [0/0] {22} ## 7 ¦--FUNCTION: funct [0/0] {4} ## 8 ¦--'(': ( [0/0] {5} ## 9 ¦--SYMBOL_FORMALS: x [0/0] {6} ## 10 ¦--')': ) [0/1] {7} ## 11 °--expr: [0/0] {19} ## 12 ¦--'{': { [0/1] {9} ## 13 ¦--expr: [0/1] {16} ## 14 ¦ ¦--expr: [0/1] {12} ## 15 ¦ ¦ °--SYMBOL: x [0/0] {10} ## 16 ¦ ¦--'+': + [0/1] {11} ## 17 ¦ °--expr: [0/0] {14} ## 18 ¦ °--NUM_CONST: 1 [0/0] {13} ## 19 °--'}': } [0/0] {15} pd <- styler:::compute_parse_data_nested(code) pd$child[[1]]$child[[3]]$child[[5]] #> id pos_id line1 col1 line2 col2 parent token terminal text short #> 1 9 11 1 24 1 24 19 '{' TRUE { { #> 2 16 12 1 26 1 30 19 expr FALSE x + 1 x + 1 #> 3 15 18 1 32 1 32 19 '}' TRUE } } #> token_before token_after stylerignore block is_cached internal #> 1 ')' SYMBOL FALSE NA FALSE FALSE #> 2 FALSE NA FALSE FALSE #> 3 NUM_CONST FALSE NA FALSE FALSE #> child #> 1 NULL #> 2 12, 11, 14, 14, 15, 17, 1, 1, 1, 26, 28, 30, 1, 1, 1, 26, 28, 30, 16, 16, 16, expr, '+', expr, FALSE, TRUE, FALSE, x, +, 1, x, +, 1, NA, SYMBOL, NA, NA, NUM_CONST, NA, FALSE, FALSE, FALSE, NA, NA, NA, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 13, 10, 1, 26, 1, 26, 12, SYMBOL, TRUE, x, x, '{', '+', FALSE, NA, FALSE, FALSE, 16, 13, 1, 30, 1, 30, 14, NUM_CONST, TRUE, 1, 1, '+', '}', FALSE, NA, FALSE, FALSE #> 3 NULL set_line_break_before_curly_opening <- function(pd_flat) { op <- pd_flat$token %in% \"'{'\" pd_flat$lag_newlines[op] <- 1L pd_flat } set_line_break_before_curly_opening_style <- function() { create_style_guide( line_break = list(set_line_break_before_curly_opening), style_guide_name = \"styler::set_line_break_before_curly_opening_style@https://github.com/r-lib/styler\", style_guide_version = read.dcf(here::here(\"DESCRIPTION\"))[, \"Version\"] ) } style_text(code, style = set_line_break_before_curly_opening_style) #> add_one <- function(x) #> { x + 1 } a <- function() # comments should remain EOL { 3 } a <- function() # comments should remain EOL { 3 } styler:::remove_line_break_before_round_closing_after_curly #> function (pd) #> { #> round_after_curly <- pd$token == \"')'\" & (pd$token_before == #> \"'}'\") #> pd$lag_newlines[round_after_curly] <- 0L #> pd #> } #> #> "},{"path":"https://styler.r-lib.org/dev/articles/customizing_styler.html","id":"cache-invalidation","dir":"Articles","previous_headings":"","what":"Cache invalidation","title":"Customizing styler","text":"Note re-distribute style guide, ’s responsibility set version style guide name create_style_guide() correctly. distribute new version style guide don’t increment version number, might drastic consequences user: circumstances (see help(\"cache_make_key\")), new style guide won’t invalidate cache although applying style guide code previously styled won’t result change. currently mechanism styler prevents making mistake.","code":""},{"path":"https://styler.r-lib.org/dev/articles/detect-alignment.html","id":"overview","dir":"Articles","previous_headings":"","what":"Overview","title":"Alignment detection","text":"Sometimes, deliberately align code make readable. styler 1.1.1.9002 (strict = TRUE, e.g. styler::style_file(..., strict = TRUE)), formatted follows: alignment detection built .1 styler >= 1.1.1.9003 detects aforementioned alignment function calls. vignette describes aligned code defined styler gives examples users can format aligned code match definition styler uses ensure code unintentionally reformatted.","code":"call( a = 3, bre = 3213232 ) call( a = 3, bre = 3213232 )"},{"path":"https://styler.r-lib.org/dev/articles/detect-alignment.html","id":"examples","dir":"Articles","previous_headings":"Overview","what":"Examples","title":"Alignment detection","text":"typical examples match styler’s definition alignment.

Note removing line breaks, always take care comments, since don’t want: become: easiest way taking care applying rule comment token interest, can checked within transformer function. transformer function tidyverse style removes line breaks round closing bracket comes curly brace looks follows: example function set_line_break_before_curly_opening() don’t need worry adding line breaks, don’t remove .","code":"add_one <- function(x) { x + 1 } add_one <- function(x) { x + 1 } code <- c(\"add_one <- function(x) { x + 1 }\") styler:::create_tree(code) ## levelName ## 1 ROOT (token: short_text [lag_newlines/spaces] {id}) ## 2 °--expr: [0/0] {23} ## 3 ¦--expr: [0/1] {3} ## 4 ¦ °--SYMBOL: add_o [0/0] {1} ## 5 ¦--LEFT_ASSIGN: <- [0/1] {2} ## 6 °--expr: [0/0] {22} ## 7 ¦--FUNCTION: funct [0/0] {4} ## 8 ¦--'(': ( [0/0] {5} ## 9 ¦--SYMBOL_FORMALS: x [0/0] {6} ## 10 ¦--')': ) [0/1] {7} ## 11 °--expr: [0/0] {19} ## 12 ¦--'{': { [0/1] {9} ## 13 ¦--expr: [0/1] {16} ## 14 ¦ ¦--expr: [0/1] {12} ## 15 ¦ ¦ °--SYMBOL: x [0/0] {10} ## 16 ¦ ¦--'+': + [0/1] {11} ## 17 ¦ °--expr: [0/0] {14} ## 18 ¦ °--NUM_CONST: 1 [0/0] {13} ## 19 °--'}': } [0/0] {15} pd <- styler:::compute_parse_data_nested(code) pd$child[[1]]$child[[3]]$child[[5]] #> id pos_id line1 col1 line2 col2 parent token terminal text short #> 1 9 11 1 24 1 24 19 '{' TRUE { { #> 2 16 12 1 26 1 30 19 expr FALSE x + 1 x + 1 #> 3 15 18 1 32 1 32 19 '}' TRUE } } #> token_before token_after stylerignore block is_cached internal #> 1 ')' SYMBOL FALSE NA FALSE FALSE #> 2 FALSE NA FALSE FALSE #> 3 NUM_CONST FALSE NA FALSE FALSE #> child #> 1 NULL #> 2 12, 11, 14, 14, 15, 17, 1, 1, 1, 26, 28, 30, 1, 1, 1, 26, 28, 30, 16, 16, 16, expr, '+', expr, FALSE, TRUE, FALSE, x, +, 1, x, +, 1, NA, SYMBOL, NA, NA, NUM_CONST, NA, FALSE, FALSE, FALSE, NA, NA, NA, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 13, 10, 1, 26, 1, 26, 12, SYMBOL, TRUE, x, x, '{', '+', FALSE, NA, FALSE, FALSE, 16, 13, 1, 30, 1, 30, 14, NUM_CONST, TRUE, 1, 1, '+', '}', FALSE, NA, FALSE, FALSE #> 3 NULL set_line_break_before_curly_opening <- function(pd_flat) { op <- pd_flat$token %in% \"'{'\" pd_flat$lag_newlines[op] <- 1L pd_flat } set_line_break_before_curly_opening_style <- function() { create_style_guide( line_break = list(set_line_break_before_curly_opening), style_guide_name = \"styler::set_line_break_before_curly_opening_style@https://github.com/r-lib/styler\", style_guide_version = read.dcf(here::here(\"DESCRIPTION\"))[, \"Version\"] ) } style_text(code, style = set_line_break_before_curly_opening_style) #> add_one <- function(x) #> { x + 1 } a <- function() # comments should remain EOL { 3 } a <- function() # comments should remain EOL { 3 } styler:::remove_line_break_before_round_closing_after_curly #> function (pd) #> { #> round_after_curly <- pd$token == \"')'\" & (pd$token_before == #> \"'}'\") #> pd$lag_newlines[round_after_curly] <- 0L #> pd #> } #> #> "},{"path":"https://styler.r-lib.org/dev/articles/customizing_styler.html","id":"cache-invalidation","dir":"Articles","previous_headings":"","what":"Cache invalidation","title":"Customizing styler","text":"Note re-distribute style guide, ’s responsibility set version style guide name create_style_guide() correctly. distribute new version style guide don’t increment version number, might drastic consequences user: circumstances (see help(\"cache_make_key\")), new style guide won’t invalidate cache although applying style guide code previously styled won’t result change. currently mechanism styler prevents making mistake.","code":""},{"path":"https://styler.r-lib.org/dev/articles/detect-alignment.html","id":"overview","dir":"Articles","previous_headings":"","what":"Overview","title":"Alignment detection","text":"Sometimes, deliberately align code make readable. styler 1.1.1.9002 (strict = TRUE, e.g. styler::style_file(..., strict = TRUE)), formatted follows: alignment detection built .1 styler >= 1.1.1.9003 detects aforementioned alignment function calls. vignette describes aligned code defined styler gives examples users can format aligned code match definition styler uses ensure code unintentionally reformatted.","code":"call( a = 3, bre = 3213232 ) call( a = 3, bre = 3213232 )"},{"path":"https://styler.r-lib.org/dev/articles/detect-alignment.html","id":"examples","dir":"Articles","previous_headings":"Overview","what":"Examples","title":"Alignment detection","text":"typical examples match styler’s definition alignment.
