The Makefile is known to work with EPICS 3.14.8 and PCRE 7.2.
In your RELEASE file define the variable <code>PCRE</code> so that
it points to the install location of PCRE.
</p>
<p>
If PCRE is already installed on your system, use the variables

If you have PCRE installed in different locations for different (cross)

If <em>precision</em> is given, it specifies the sub-expression whose match

<h2>14. Regular Expresion Substitution Pseudo-Converter (<code>%#/<em>regex</em>/<em>subst</em>/</code>)</h2>
<p>
This is a variant of the previous converter (note the <code>#</code>)
but instead of returning the matching string,
it can be used as a pre-processor for input or
as a post-processor for output.
</p>
<p>
Matches of the <em>regex</em> are replaced by the string <em>subst</em> with all
<code>&</code> or <code>\0</code> in <em>subst</em> replaced with the match itself and all
<code>\1</code> through <code>\9</code> replaced with the match of the corresponding sub-expression.
To get a literal <code>&</code> or <code>\</code> or <code>/</code> in the substitution write
<code>\&</code> or <code>\\</code> or <code>\/</code>.
There is no way to specify literal bytes with values less or equal to 9 in the
substitution!
</p>
<p>
If <em>width</em> is specified, it limits the number of characters processed.
If the <code>-</code> flag is used (i.e. <em>width</em> looks like a negative number)
only the last <em>width</em> characters are processed, else the first.
Without <em>width</em> (or 0) all available characters are processed.
</p>
<p>
If <em>precision</em> is specified, it indicates which matches to replace.
With the <code>+</code> flag given, <em>precision</em> is the maximum
number of matches to replace.
Otherwise <em>precision</em> is the index (counting from 1) of the match to replace.
Without <em>precision</em> (or 0), all matches are replaced.
</p>
<p>
In input this converter pre-processes data received from the device before
following converters read it.
Converters preceding this one will read unmodified input.
Thus place this converter before those whose input should be pre-processed.
</p>
<p>
In output it post-processes data already formatted by preceding converters
before sending it to the device.
Converters following this one will send their output unmodified.
Thus place this converter after those whose output should be post-processed.
</p>

Examples:
<div class="indent">
<code>%#+-10.2/ab/X/</code> replaces the string <code>ab</code> with <code>X</code>
maximal 2 times in the last 10 characters.
(<code>abcabcabcabc</code> becomes <code>abcXcXcabc</code>)
</div>
<div class="indent">
<code>%#/\\/\//</code> replaces all <code>\</code> with <code>/</code>
(<code>\dir\file</code> becomes <code>/dir/file</code>)
</div>
<div class="indent">
<code>%#/..\B/&:/</code> inserts <code>:</code> after every second character
which is not at the end of a word.
(<code>0b19353134</code> becomes <code>0b:19:35:31:34</code>)
</div>
