<h2>List of selection helpers</h2>

<h3>Description</h3>

<p>This list contains all selection helpers exported in tidyselect. It
was useful when you wanted to embed the helpers in your API without
having to track addition of new helpers in tidyselect. However the
selection helpers are now always embedded in the DSL.
</p>

<h3>Usage</h3>

<pre>
vars_select_helpers
</pre>

<h3>Format</h3>

<p>An object of class <code>list</code> of length 11.
</p>

<h3>Examples</h3>

<pre>
# You can easily embed the helpers by burying them in the scopes of
# input quosures. For this example we need an environment where
# tidyselect is not attached:
local(envir = baseenv(), {
  vars &lt;- c("foo", "bar", "baz")
  helpers &lt;- tidyselect::vars_select_helpers

my_select &lt;- function(...) {
    quos &lt;- rlang::quos(...)
    quos &lt;- lapply(quos, rlang::env_bury, !!! helpers)

tidyselect::vars_select(vars, !!! quos)
  }

# The user can now call my_select() with helpers without having
  # to attach tidyselect:
  my_select(starts_with("b"))
})
</pre>
