is_lint_level: Is this an expression- or a file-level source object?

In r-lib/lintr: A 'Linter' for R Code

Is this an expression- or a file-level source object?

Description

Helper for determining whether the current source_expression contains all expressions in the current file, or just a single expression.

Usage

is_lint_level(source_expression, level = c("expression", "file"))

Arguments

source_expression	A parsed expression object, i.e., an element of the object returned by get_source_expressions().
level	Which level of expression is being tested? "expression" means an individual expression, while "file" means all expressions in the current file are available.

Examples

tmp <- tempfile()
writeLines(c("x <- 1", "y <- x + 1"), tmp)
source_exprs <- get_source_expressions(tmp)
is_lint_level(source_exprs$expressions[[1L]], level = "expression")
is_lint_level(source_exprs$expressions[[1L]], level = "file")
is_lint_level(source_exprs$expressions[[3L]], level = "expression")
is_lint_level(source_exprs$expressions[[3L]], level = "file")
unlink(tmp)
