tergo-lib

Description

This is the main entry point for tergo as a formatting tool. It is a library, written in Rust, which exposes basic functions to format source code of the R programming language given a user-supplied or default formatting configuration.

Configuration

You can see an example of a configuration file in the examples directory.

• indent (i32): the number of characters constituting a single indent. Default: 2.

• line_length (i32): the maximum length of the line allowed in the formatted output. Default: 120.

• embracing_op_no_nl (bool): whether to remove line breaks inside the embracing operator ({{ }}). See: https://style.tidyverse.org/syntax.html#embracing Default: true.

• allow_nl_after_assignment (bool): whether to allow new lines after any kind of assignment operator (=, <-, :=) for a very long binary expressions. Default: false.

• space_before_complex_rhs_in_formula (bool): whether to add a space before complex expression in formulas. Default: true. See https://style.tidyverse.org/syntax.html#infix-operators.

• strip_suffix_whitespace_in_function_defs (bool): whether to strip any remaining whitespace (including new lines) from ends of the function definitions. Example:

  function() {
    TRUE
  
  }
  

  If strip_suffix_whitespace_in_function_defs is set to true, then the above is formatted to:

  function() {
    TRUE
  }
  

  Default: true.

• function_line_breaks (string): possible values include: "single", "double", "hanging". See https://style.tidyverse.org/functions.html#multi-line-function-definitions "double" works the same as "single", except the amount of indent for function arguments is doubled. Default: "hanging".

• insert_newline_in_quote_call (bool): whether to insert a new line in calls to quote where the inside expression is very long and contains mandatory line breaks (like a closure with {}). Default: true.
