stri_opts_brkiter {stringi} | R Documentation

## Generate a List with BreakIterator Settings

### Description

A convenience function to tune the ICU `BreakIterator`'s behavior in some text boundary analysis functions, see stringi-search-boundaries.

### Usage

    stri_opts_brkiter(type, locale, skip_word_none, skip_word_number,
      skip_word_letter, skip_word_kana, skip_word_ideo, skip_line_soft,
      skip_line_hard, skip_sentence_term, skip_sentence_sep, ...)

### Arguments

`type` | single string; break iterator type, one of `character`, `line_break`, `sentence`, or `word`; see stringi-search-boundaries
`locale` | single string, `NULL` or `""` for default locale
`skip_word_none` | logical; perform no action for "words" that do not fit into any other categories
`skip_word_number` | logical; perform no action for words that appear to be numbers
`skip_word_letter` | logical; perform no action for words that contain letters, excluding hiragana, katakana, or ideographic characters
`skip_word_kana` | logical; perform no action for words containing kana characters
`skip_word_ideo` | logical; perform no action for words containing ideographic characters
`skip_line_soft` | logical; perform no action for soft line breaks, i.e. positions at which a line break is acceptable but not required
`skip_line_hard` | logical; perform no action for hard, or mandatory line breaks
`skip_sentence_term` | logical; perform no action for sentences ending with a sentence terminator ("`.`", "`,`", "`?`", "`!`"), possibly followed by a hard separator (`CR`, `LF`, `PS`, etc.)
`skip_sentence_sep` | logical; perform no action for sentences that do not contain an ending sentence terminator, but are ended by a hard separator or end of input
`...` | any other arguments to this function are purposely ignored

### Details

The `skip_*` family of settings may be used to prevent performing any special actions on particular types of text boundaries, e.g. in case of the `stri_locate_all_boundaries` and `stri_split_boundaries` functions.

### Value

Returns a named list object. Omitted `skip_*` values act as they have been set to `FALSE`.
