parse_export_specs

Find exported names in parsed module source

Description

Find exported names in parsed module source

Usage

parse_export_specs(info, exprs, mod_ns)

use_call

static_assign_calls

assign_calls

is_static_assign_call(call)

is_assign_call(call)

block_is_assign(block)

block_is_use_call(block)

block_is_exported(block)

block_name(block)

Arguments

`info`	The module info.
`exprs`	The list of expressions of the parsed module.
`mod_ns`	The module namespace after evaluating the expressions.
`call`	A call to test.
`block`	A roxygen2 block to inspect.

Format

An object of class call of length 3.

An object of class list of length 4.

An object of class list of length 6.

Value

parse_export_specs returns a potentially empty character vector of exported names.

Note

There are two situations in which the @export tag can be applied:

When applied to assignments, the assigned name is exported.
When applied to a box::use call, the imported names are exported. This can be the module name itself, any attached names, or both. All names introduced by the box::use call are exported. See use for the rules governing what names are introduced into the scope, and thus exported.

In any other situation, applying the @export tag is an error.
