lintr (version 3.1.2)

object_length_linter: Object length linter

Description

Check that object names are not too long. The length of an object name is defined as the length in characters, after removing extraneous parts:

Usage

object_length_linter(length = 30L)

Arguments

length

maximum variable name length allowed.

Tags

configurable, default, executing, readability, style

Details

• generic prefixes for implementations of S3 generics, e.g. as.data.frame.my_class has length 8.

• leading ., e.g. .my_hidden_function has length 18.

• "%%" for infix operators, e.g. %my_op% has length 5.

• trailing <- for assignment functions, e.g. my_attr<- has length 7.

Note that this behavior relies in part on having packages in your Imports available; see the detailed note in object_name_linter() for more details.

# will produce lints
lint(
  text = "very_very_long_variable_name <- 1L",
  linters = object_length_linter(length = 10L)
)

# okay
lint(
  text = "very_very_long_variable_name <- 1L",
  linters = object_length_linter(length = 30L)
)

lint(
  text = "var <- 1L",
  linters = object_length_linter(length = 10L)
)
