cache_by_expression: Cache text

In r-lib/styler: Non-Invasive Pretty Printing of R Code

Cache text

Description

Splits text into expressions and adds these to the cache. Note that top-level comments are not cached because caching and in particular checking if they are cached is too expensive. Comments may be cached as part of the whole text (as opposed to on an expression by expression basis) using cache_write() directly. Also, we must not cache stylerignore sequence, because we might see the same expression that does not comply with the style guide outside a stylerignore sequence and wrongly think we should leave it as is.

Usage

cache_by_expression(text, transformers, more_specs)

Arguments

text	A character vector with one or more expressions.
transformers	A list of transformer functions, because we can only know if text is already correct if we know which transformer function it should be styled with.
more_specs	A named vector coercible to character that determines the styling but are style guide independent, such as include_roxygen_examples or base_indention.
