zap_srcref

There are a number of situations where R creates source references:<ul>
<li>Reading R code from a file with <code><a href="/link/source()?package=rlang&version=1.1.0" data-mini-rdoc="rlang::source()">source()</a></code> and <code><a href="/link/parse()?package=rlang&version=1.1.0" data-mini-rdoc="rlang::parse()">parse()</a></code> might save
source references inside calls to <code>function</code> and <code>{</code>.</li>
<li><code><a href="/link/sys.call()?package=rlang&version=1.1.0" data-mini-rdoc="rlang::sys.call()">sys.call()</a></code> includes a source reference if possible.</li>
<li>Creating a closure stores the source reference from the call to
<code>function</code>, if any.</li>
</ul>These source references take up space and might cause a number of
issues. <code>zap_srcref()</code> recursively walks through expressions and
functions to remove all source references.

A toolbox for working with base types, core R features
like the condition system, and core 'Tidyverse' features like tidy
evaluation.

Arguments

There are a number of situations where R creates source references:<ul>
<li>Reading R code from a file with <code><a href='https://rdrr.io/r/base/source.html'>source()</a></code> and <code><a href='https://rdrr.io/r/base/parse.html'>parse()</a></code> might save
source references inside calls to <code>function</code> and <code>{</code>.</li>
<li><code><a href='https://rdrr.io/r/base/sys.parent.html'>sys.call()</a></code> includes a source reference if possible.</li>
<li>Creating a closure stores the source reference from the call to
<code>function</code>, if any.</li>
</ul>

These source references take up space and might cause a number of
issues. <code>zap_srcref()</code> recursively walks through expressions and
functions to remove all source references.
