tl;dr - use <em>svx2qm.py</em>. Look at the output at:<br>

<h2>QMs - the fourfold path</h2>
|
|||
|
|
<p>You will be familiar with <a href="../survey/qmentry.html">documenting newly found QMs</a> in the survex file when you type it in. But QMs are only useful if they can be easily scanned by people planning the next pushing trip. That's what we are discussing here.
|
|||
|
|
|
|||
|
|
<p>There are four ways we have used to manage QMs:
|
|||
|
|
<ol>
|
|||
|
|
<li><strong>Perl script</strong> - Historically QMs were not in the survex file but typed up in a separate list <var>qms.csv</var> for each cave system. A perl script turned that into an HTML file for the website.
|
|||
|
|
<li><strong>Perl + troggle</strong> - One of troggle's input parsers "QM parser" is specifically designed to import the three HTML files produced from <var>qms.csv</var> but doesn't do anything with that data (yet).
|
|||
|
|
<li><strong>Python script</strong> - Phil Withnall's 2019 script <em>svx2qm.py</em> scans all the QMs in a single survex file. See below for how to run it on all survex files.
|
|||
|
|
<li><strong>New troggle</strong> - Sam's recent addition to troggle's "survex parser" makes it recognise and store QMs when it parses the survex files.
|
|||
|
|
</ol>
|
|||
|
|
|
|||
|
|
<p>QMs all use <a href="../../qm.html">the same QM description conventions</a>.
|
|||
|
|
|
|||
|
|
<h4 id="tabqmsqms">tablize-qms.pl</h4>
|
|||
|
|
<p>This is a perl script dating from November 2004.
|
|||
|
|
|
|||
|
|
<p>it takes a <em>hand-edited</em> CSV file name as the program's argument and generates an HTML page listing all the QMs.
|
|||
|
|
<p><a href="../../1623/258/tablize-qms.pl" download>Copies of it</a> live in the three cave file folders in <em>:expoweb:/1623/</em>, in <em>258/, 234/</em>, and <em> 204/</em> . These generated html files are live pages in the cave descriptions: <br />
|
|||
|
|
<a href="../../1623/258/qm.html">/1623/258/qm.html</a><br />
|
|||
|
|
<a href="../../1623/234/qm.html">/1623/234/qm.html</a><br />
|
|||
|
|
<a href="../../1623/204/qm.html">/1623/204/qm.html</a><br />
|
|||
|
|
<p>Note that the <var>qms.csv</var> file file used as input by this script is an <em>entirely different format and table structure</em> from the <var>qms.csv</var> file produced by <a href="#svx2qm">svx2qm.py</a>.
|
|||
|
|
|
|||
|
|
<p>There are also three versions of the QM list for cave 161 (Kaninchenhohle) apparently produced by this method but hand-edited:<br />
|
|||
|
|
<a href="../../1623/161/qmaven.html">/1623/161/qmaven.html</a> 1996 version<br />
|
|||
|
|
<a href="../../1623/161/qmtodo.html">/1623/161/qmtodo.html</a> 1998 version<br />
|
|||
|
|
<a href="../../1623/161/qmdone.html">/1623/161/qmdone.html</a> 1999 (incomplete) version
|
|||
|
|
</p>
|
|||
|
|
<p>In the /1623/204/ folder there is a script <em>qmreader.pl</em> which apparently does the inverse of
|
|||
|
|
<em>tablize-qms.pl</em>: it transforms a QMs' HTML file into a CSV file.
|
|||
|
|
|
|||
|
|
|
|||
|
|
<h4 id="qms.py">troggle/parsers/qms.py</a></h4>
|
|||
|
|
<p>The parser <em>troggle/parsers/qms.py</em> currently imports those same <var>qm.csv</var> files from the perl script into troggle using a mixture of csv and html parsers:
|
|||
|
|
<code><pre>parseCaveQMs(cave='stein',inputFile=r"1623/204/qm.csv")
|
|||
|
|
parseCaveQMs(cave='hauch',inputFile=r"1623/234/qm.csv")
|
|||
|
|
parseCaveQMs(cave='kh', inputFile="1623/161/qmtodo.htm")
|
|||
|
|
#parseCaveQMs(cave='balkonhoehle',inputFile=r"1623/264/qm.csv")</pre></code>
|
|||
|
|
but does not apparently have any output webpage to display them (yet).
|
|||
|
|
</p>
|
|||
|
|
<p>Note that the hand-edited <var>qm.csv</var> for Balkonhohle was apparently abandoned unfinished as we transitioned to putting the QMs in the survex files instead. It contains QMs from 2014 and 2016:<br />
|
|||
|
|
<a href="../../1623/264/qm.csv" download>/1623/264/qm.csv</a> - unused <br/>
|
|||
|
|
|
|||
|
|
<h4 id="svx2qm">svx2qm.py</a></h4>
|
|||
|
|
<p>Philip Withnall's 2019 QM extractor <em>svx2qm.py</em> (in :loser:/qms/) can be used to generate a list of all the QMs in all the svx files in either text or CSV format. When run together with <em>file</em> and <em>xargs</em> it will produce a output listing all the QMs:
|
|||
|
|
<pre><code>cd loser
|
|||
|
|
find -name '*.svx' | xargs qms/svx2qm.py --format csv
|
|||
|
|
</code></pre>
|
|||
|
|
and --format human produces a simple text format.
|
|||
|
|
<p>
|
|||
|
|
<b>
|
|||
|
|
FINISH - the 2019 copies are online HERE and HERE
|
|||
|
|
</b>
|
|||
|
|
<p>
|
|||
|
|
This will work on all survex *.svx files even those which have not yet been run through the troggle import process.
|
|||
|
|
<p>Phil says (13 April 2020): <em>"The generated files are not meant to be served by the webserver, it’s a tool for people to run locally. Someone could modify it to create HTML output (or post-process the CSV output to do the same), but that is work still to be done."</em>

<h4 id="samqms">Sam's parser additions</a></h4>
|

|
|
<p>Troggle <em>troggle/parsers/survex.py</em> currently parses and stores all the QMs it finds in survex files. The tables where the data is put are listed in <a href="datamodel.html">the current data model</a> including structure for ticking them off.
|
|||
|
|
<p>There is not yet a troggle report listing the QMs.

<h4 id="find-dead-qms">find-dead-qms.py</h4>
|

|
|
<p>This finds references to <em>completed</em> qms in the qm.csv files in the cave folders (/1623/ etc.) in the :expoweb: repository. It looks to see which QMs have been completed but where there is not yet a matching text in the cave description.

<br>

Hi Philip,
|
|||
|
|
|
|||
|
|
Hope you’re well, thanks for getting in touch about this.
|
|||
|
|
|
|||
|
|
The generated files are not meant to be served by the webserver, it’s a tool for people to run locally.
|
|||
|
|
Someone could modify it to create HTML output (or post-process the CSV output to do the same),
|
|||
|
|
but that is work still to be done.
|
|||
|
|
|
|||
|
|
I can't see any problem with moving it all to expoweb/scripts/ - so long as it is
|
|||
|
|
run with the loser top level directory specified - but I might be mistaken:
|
|||
|
|
find /home/expo/loser -name '*.svx' | xargs ./svx2qm.py --format human
|
|||
|
|
and it should go into the Makefile too at some point.
|
|||
|
|
|
|||
|
|
Feel free to move it wherever; I am not planning on doing any further work on it.
|
|||
|
|
The script itself just expects to be passed some (relative or absolute) paths to SVX files,
|
|||
|
|
so can be placed wherever, as long as it’s passed appropriate relative paths.
|
|||
|
|
|
|||
|
|
I haven’t written any other scripts which post-process the data or otherwise format it.
|
|||
|
|
|
|||
|
|
I guess it all depends on what questions people are trying to answer using the QM data,
|
|||
|
|
as to how (and where) best to present it. I’m afraid I don’t have any suggestions there.
|
|||
|

:Rob Watson wrote some documentation about QMs
|
|||
|
|
:http://expo.survex.com/handbook/survey/qmentry.html
|
|||
|
|
:is there anything subtle missing as to how they are used ?
|
|||
|
|
|
|||
|
|
Nope, I think Rob’s page covers it all. That page also documents the correct QM format
|
|||
|
|
which is what svx2qm.py understands. (There were some older or artisanal QM formats
|
|||
|
|
floating around at one point, although I think I reformatted them all so the tool
|
|||
|
|
would understand them, and so people would hopefully standardise on what Rob’s
|
|||
|
|
documented from then on.)
