They are definitely going away, so knowing if your favourite app is on the chopping block is likely a good idea.<\/p>\n<p>You can get this information via the &#8220;About This Mac&#8221;\u0362&#8221;System Report&#8221; app and sorting via one of the table fields.<\/p>\n<p>R folks are data folks and we know we can do better than that. But, first we need to get the data. Thankfully, we can get this via the <a href=\"https:\/\/ss64.com\/osx\/system_profiler.html\"><code>system_profiler<\/code><\/a> command-line utility since it can both display user-friendly information in the terminal and also generate an XML version of the information to work with. We won&#8217;t need to head to the terminal for this work, though, since there are many ways to execute the command from R and read the generated output.<\/p>\n<h3>Executing System Calls from R<\/h3>\n<p>Base R provides two core methods for issuing a system call:<\/p>\n<ul>\n<li><code>system()<\/code><\/li>\n<li><code>system2()<\/code><\/li>\n<\/ul>\n<p>Note that there are other functions provided with a base R installation that can also issue system commands and process the &#8220;piped&#8221; output, but we&#8217;ll focus on these deliberate invocation ones.<\/p>\n<p>Functions in two other packages can also assist with this task and we&#8217;ll include a look at:<\/p>\n<ul>\n<li><code>processx::run()<\/code><\/li>\n<li><code>sys::exec_internal()<\/code><\/li>\n<\/ul>\n<p>as well.<\/p>\n<p>Why leave base R for this task? Truthfully, we really don&#8217;t <em>need<\/em> to, but both <code>sys<\/code> and <code>processx<\/code> have other tasks which do make them handy tools in your package toolbox. Having said that, keep reading since we&#8217;re going to end up <em>not<\/em> choosing the built-in functions for this task.<\/p>\n<p>This is the command line we need to execute:<\/p>\n<pre><code class=\"language-bash\">system_profiler -xml -detailLevel full SPApplicationsDataType\n<\/code><\/pre>\n<p>Let&#8217;s load up all the packages we&#8217;ll be needing and execute this command-line all four ways, then briefly discuss the differences:<\/p>\n<pre><code class=\"language-r\">library(sys)\nlibrary(processx)\nlibrary(microbenchmark)\nlibrary(xml2)\nlibrary(tidyverse)\n\nsystem(\n  command = \"system_profiler -xml -detailLevel full SPApplicationsDataType\",\n  intern = TRUE\n) -> apps_system\n\nstr(apps_system)\n##  chr [1:10665] \"<?xml version=\\\"1.0\\\" encoding=\\\"UTF-8\\\"?>\" ...\n\nsystem2(\n  command = \"system_profiler\",\n  args = c(\"-xml\", \"-detailLevel\", \"full\", \"SPApplicationsDataType\"),\n  stdout = TRUE\n) -> apps_system2\n\nstr(apps_system2)\n##  chr [1:10665] \"<?xml version=\\\"1.0\\\" encoding=\\\"UTF-8\\\"?>\" ...\n\nprocessx::run(\n  command = \"system_profiler\",\n  args = c(\"-xml\", \"-detailLevel\", \"full\", \"SPApplicationsDataType\"),\n  spinner = TRUE\n) -> apps_processx_run\n\nstr(apps_processx_run)\n## List of 4\n##  $ status : int 0\n##  $ stdout : chr \"XML STRING THAT prism.js won't let me show\"\n##  $ stderr : chr \"\"\n##  $ timeout: logi FALSE\n\nsys::exec_internal(\n  cmd = \"system_profiler\",\n  args = c(\"-xml\", \"-detailLevel\", \"full\", \"SPApplicationsDataType\")\n) -> apps_sys_exec_internal\n\nstr(apps_sys_exec_internal)\n## List of 3\n##  $ status: int 0\n##  $ stdout: raw [1:331133] 3c 3f 78 6d ...\n##  $ stderr: raw(0) <\/code><\/pre>\n<p>The core difference between <code>system()<\/code> and the rest is that <em>you<\/em> need to <a href=\"https:\/\/stat.ethz.ch\/R-manual\/R-devel\/library\/base\/html\/shQuote.html\"><code>shQuote()<\/code>?<\/a> for <code>system()<\/code> whereas that&#8217;s taken care of for you by the others (so they&#8217;re a bit safer by default since you&#8217;re more than likely going to forget to <code>shQuote()<\/code>).<\/p>\n<p>You can definitely notice the main differences in return objects. The built-in functions just give us the character data from the standard output stream (<code>stdout<\/code>) and the last two return a more structured object that provides more explicit information about the job we just executed. The base ones can provide this detail, but it&#8217;s a twisty maze of remembering which options do what vs the more (IMO) straightforward approach both <code>processx<\/code> and <code>sys<\/code> take.<\/p>\n<p>You&#8217;ll also notice a difference in <code>stdout<\/code> between <code>processx<\/code> and <code>sys<\/code> with the latter giving us a raw vector vs a character vector. This gives us a great deal of power and flexibility. It also turns out to be a great choice for processing command-line-generated XML data. Here&#8217;s why:<\/p>\n<pre><code class=\"language-r\">microbenchmark(\n  sys = xml2::read_xml(apps_sys_exec_internal$stdout),\n  processx = xml2::read_xml(apps_processx_run$stdout)\n)\n## Unit: milliseconds\n##      expr      min       lq      mean    median        uq      max neval\n##       sys 4.086492  4.60078  9.085143  5.508814  5.906942 207.6495   100\n##  processx 9.510356 10.98282 14.275499 12.054810 13.292234 163.9870   100<\/code><\/pre>\n<p>It turns out <code>xml2::read_xml()<\/code> makes much quicker work of the raw vector data (though, I mean, <em>really<\/em>&mdash;are we really going to care about those ~5ms IRL?).<\/p>\n<p>We&#8217;ll move on to the real reason for the post, but definitely explore both <code>sys<\/code> and <code>processx<\/code> since they are both super-handy packages.<\/p>\n<h3><em>&#8220;Can we please just find the 32-bit apps already?&#8221;<\/em><\/h3>\n<p>No problem. Well, actually, there is a minor annoyance. These are <a href=\"https:\/\/developer.apple.com\/library\/archive\/documentation\/Cocoa\/Conceptual\/PropertyLists\/UnderstandXMLPlist\/UnderstandXMLPlist.html\">property list XML files<\/a> and I&#8217;ll confess that I truly hate this format. There are &#8220;dictionary arrays&#8221; of <code>key<\/code> and <code>value<\/code> nodes, but those nodes are siblings vs directly associated pairs. So, we have to use the sibling relationship to work with them. It&#8217;s not <em>hard<\/em>, per se, just (again, IMO) suboptimal.<\/p>\n<p>Let&#8217;s take a look at it:<\/p>\n<pre><code class=\"language-r\">apps <- read_xml(apps_sys_exec_internal$stdout)\n\nxml_find_all(apps, \"\/\/array\/dict\")\n## {xml_nodeset (476)}\n##  [1] <dict>\\n  <key>_SPCommandLineArguments<\/key>\\n  <array>\\n    <string> ...\n##  [2] <dict>\\n  <key>_name<\/key>\\n  <string>Sublime Text<\/string>\\n  <key>h ...\n##  [3] <dict>\\n  <key>_name<\/key>\\n  <string>System Preferences<\/string>\\n   ...\n##  [4] <dict>\\n  <key>_name<\/key>\\n  <string>Google Chrome Canary<\/string>\\n ...\n##  [5] <dict>\\n  <key>_name<\/key>\\n  <string>Google Chrome<\/string>\\n  <key> ...\n##  [6] <dict>\\n  <key>_name<\/key>\\n  <string>Dropbox<\/string>\\n  <key>has64B ...\n##  [7] <dict>\\n  <key>_name<\/key>\\n  <string>Keypad<\/string>\\n  <key>has64Bi ...\n##  [8] <dict>\\n  <key>_name<\/key>\\n  <string>Garmin WebUpdater<\/string>\\n  < ...\n##  [9] <dict>\\n  <key>_name<\/key>\\n  <string>LaTeXiT<\/string>\\n  <key>has64B ...\n## [10] <dict>\\n  <key>_name<\/key>\\n  <string>CocoaPacketAnalyzer<\/string>\\n  ...\n## [11] <dict>\\n  <key>_name<\/key>\\n  <string>Janetter<\/string>\\n  <key>has64 ...\n## [12] <dict>\\n  <key>_name<\/key>\\n  <string>VMware Fusion<\/string>\\n  <key> ...\n## [13] <dict>\\n  <key>_name<\/key>\\n  <string>Photo Library Migration Utility ...\n## [14] <dict>\\n  <key>_name<\/key>\\n  <string>Setup Assistant<\/string>\\n  <ke ...\n## [15] <dict>\\n  <key>_name<\/key>\\n  <string>Siri<\/string>\\n  <key>has64BitI ...\n## [16] <dict>\\n  <key>_name<\/key>\\n  <string>Software Update<\/string>\\n  <ke ...\n## [17] <dict>\\n  <key>_name<\/key>\\n  <string>Spotlight<\/string>\\n  <key>has6 ...\n## [18] <dict>\\n  <key>_name<\/key>\\n  <string>Stocks<\/string>\\n  <key>has64Bi ...\n## [19] <dict>\\n  <key>_name<\/key>\\n  <string>SystemUIServer<\/string>\\n  <key ...\n## [20] <dict>\\n  <key>_name<\/key>\\n  <string>UniversalAccessControl<\/string> ...\n## ...<\/code><\/pre>\n<p>Let&#8217;s look at a sample record using <code>xml_view()<\/code> from the <code>htmltidy<\/code> package:<\/p>\n<pre><code class=\"language-r\">xml_find_all(apps, \"\/\/array\/dict[key='_name']\")[1] %>% \n  htmltidy::xml_view()<\/code><\/pre>\n<p><a href=\"https:\/\/rud.is\/b\/2018\/08\/24\/friday-rstats-twofer-finding-macos-32-bit-apps-processing-data-from-system-commands\/screen-shot-2018-08-24-at-4-58-41-am\/\" rel=\"attachment wp-att-11431\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"11431\" data-permalink=\"https:\/\/rud.is\/b\/2018\/08\/24\/friday-rstats-twofer-finding-macos-32-bit-apps-processing-data-from-system-commands\/screen-shot-2018-08-24-at-4-58-41-am\/\" data-orig-file=\"https:\/\/i0.wp.com\/rud.is\/b\/wp-content\/uploads\/2018\/08\/Screen-Shot-2018-08-24-at-4.58.41-AM.png?fit=1640%2C836&amp;ssl=1\" data-orig-size=\"1640,836\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"xml_view\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/rud.is\/b\/wp-content\/uploads\/2018\/08\/Screen-Shot-2018-08-24-at-4.58.41-AM.png?fit=510%2C260&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/rud.is\/b\/wp-content\/uploads\/2018\/08\/Screen-Shot-2018-08-24-at-4.58.41-AM.png?resize=510%2C260&#038;ssl=1\" alt=\"\" width=\"510\" height=\"260\" class=\"aligncenter size-full wp-image-11431\" \/><\/a><\/p>\n<p>Be wary of using <code>xml_view()<\/code> on giant XML structures since it&#8217;ll freeze up RStudio for a bit and even slows down Chrome since the resultant, composed DOM object can get ginormous.<\/p>\n<p>Now we know we can use <code>has64BitIntelCode<\/code> for filtering once we get to the data.
