<h2>Introduction</h2>
<p>
The <strong>Formula Support</strong> option enables dynamic replacements that go beyond plain text substitution. Instead of a fixed replacement string, you write a small expression that is evaluated for each match. Two engines are available: <strong>Lua</strong> and <strong>ExprTk</strong>. Switch via the <code>(L)</code> / <code>(E)</code> indicator next to the option.
</p>
</section>
<section id="EngineOverview">
<h2>Engine Overview</h2>
<p>When <strong>Formula Support</strong> is enabled, replacements run through a formula engine. MultiReplace ships with two: <strong>Lua</strong> and <strong>ExprTk</strong>. Switch via the <code>(L)</code> / <code>(E)</code> indicator next to the <strong>Formula Support</strong> checkbox. The choice is per tab and persists across sessions.</p>
<p><strong>Quick guidance:</strong> for most everyday jobs — doing math on a captured number, numbering matches, formatting a date or duration, a quick conditional — <strong>ExprTk</strong> is the easiest start: a single short formula, with captures available as numbers (<code>num(N)</code>) or text (<code>txt(N)</code>) without any conversion step. Choose <strong>Lua</strong> when the task grows into real programming: loops, multi-step logic, lookup tables, or loading external files. Both read and write UTF-8 and both handle everyday string work, so for simple tasks either one is fine — but if you're unsure, start with ExprTk and switch to Lua only when you actually need its extra power.</p>
<table class="optionsTable">
<tr>
<th> </th>
<th>Lua</th>
<th>ExprTk</th>
</tr>
<tr>
<td><strong>Best for</strong></td>
<td>Logic-heavy text work: branching, lookups, loops, external files</td>
<td>Number crunching and tidy one-line formulas; dates and durations</td>
</tr>
<tr>
<td><strong>Style</strong></td>
<td>A small script — multiple statements, variables, control flow</td>
<td>One expression per replacement, kept short</td>
</tr>
<tr>
<td><strong>Captures</strong></td>
<td><code>CAP1</code>, <code>CAP2</code>, … (text; <code>tonum()</code> for math)</td>
<td><code>txt(N)</code> for text, <code>num(N)</code> for math — no conversion step</td>
</tr>
<tr>
<td><strong>Strings</strong></td>
<td>Full standard string library</td>
<td>Everyday toolkit: <code>slice</code>, <code>split</code>, <code>trim</code>, <code>find</code>, <code>replace</code>, join with <code>+</code></td>
</tr>
<tr>
<td><strong>Math</strong></td>
<td>The basics, build up the rest in code</td>
<td>Large built-in set out of the box (trig, stats, rounding, min/max/avg over many values)</td>
</tr>
<tr>
<td><strong>Dates</strong></td>
<td><code>os.date</code> / <code>os.time</code>, full locale handling</td>
<td><code>d:</code> output format + <code>todate()</code> for reading dates back in</td>
</tr>
<tr>
<td><strong>Formatting</strong></td>
<td><code>string.format</code> (printf-style)</td>
<td>Inline <code>~</code> spec: width, padding, sign, hex/binary, durations, date layout</td>
</tr>
<tr>
<td><strong>Logic & loops</strong></td>
<td>Everything: <code>if/else</code>, <code>while</code>, <code>for</code>, <code>repeat</code></td>
<td><code>if</code>-style conditionals inside the expression; no loops</td>
</tr>
<tr>
<td><strong>External files</strong></td>
<td>Load data lookups and variables from files, plus reusable function libraries (<code>lkp</code>, <code>lvars</code>, <code>lcmd</code>)</td>
<td>Load reusable function libraries from <code>.elib</code> files (<code>loadlib</code>)</td>
</tr>
<tr>
<td><strong>Speed</strong></td>
<td>Fast enough for anything</td>
<td>Very fast for pure number work</td>
</tr>

<h2>Quick Start: Lua</h2>
<ol>
<li>
<strong>Enable "Formula Support"</strong><br>
Check the "<strong>Formula Support</strong>" option in the Replace interface.
</li>
<li>
<strong>Use a Command</strong><br><br>
<p><strong>Option 1:</strong> <a href="#setstrorcalc"><code>set(...)</code></a> → Directly replaces with a value or calculation.</p>
<ul>
<li><strong>Find</strong>: <code>(\d+)</code></li>
<li><strong>Replace</strong>: <code>set(tonum(CAP1) * 2)</code></li>
<li><strong>Result</strong>: Doubles numbers (e.g., <code>50</code> → <code>100</code>).</li>
</ul>
<em>(Enable 'Regular Expression' in 'Search Mode' to use <code>(\d+)</code> as a capture group.)</em>
<p><strong>Option 2:</strong> <a href="#condcondition-trueval-falseval"><code>cond(...)</code></a> → Conditional replacement.</p>
<ul>
<li><strong>Find</strong>: <code>word</code></li>
<li><strong>Replace</strong>: <code>cond(CNT==1, "FirstWord")</code></li>
<li><strong>Result</strong>: Changes only the <strong>first</strong> occurrence of "word" to "FirstWord".</li>
</ul>
</li>
<li>
<strong>Use Basic Variables:</strong>
<ul>
<li><strong><code>CNT</code></strong>: Inserts the current match number (e.g., "1" for the first match, "2" for the second).</li>
<li><strong><code>CAP1</code>, <code>CAP2</code>, etc.:</strong> Holds captured groups when Regex is enabled.<br>
<blockquote>
<strong>Capture Groups:</strong><br>
With a regex in parentheses <code>(...)</code>, matched text is stored in <code>CAP</code> variables (e.g., <code>(\d+)</code> in <code>Item 123</code> stores <code>123</code> in <code>CAP1</code>). For more details, refer to regex documentation.

<h2>Variables Overview</h2>
<p>All variables below are registered under both upper- and lowercase. Pick whichever style reads better — <code>CNT</code> and <code>cnt</code> refer to the same value, as do <code>match</code> and <code>MATCH</code>, <code>cap1</code> and <code>CAP1</code>, and so on.</p>
<p><strong>Function names are also case-insensitive.</strong> <code>num(1)</code>, <code>Num(1)</code>, and <code>NUM(1)</code> all call the same function; the same applies to <code>numprev</code> / <code>NumPrev</code> / <code>NUMPREV</code>, <code>txt</code> / <code>TXT</code>, and every other built-in. This is enforced consistently from the parser through to the match-history analyser.</p>
<table class="optionsTable">
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
<tr>
<td><strong>CNT</strong> / <strong>cnt</strong></td>
<td>Count of the detected string.</td>
</tr>
<tr>
<td><strong>LCNT</strong> / <strong>lcnt</strong></td>
<td>Count of the detected string within the line.</td>
</tr>
<tr>
<td><strong>LINE</strong> / <strong>line</strong></td>
<td>Line number where the string is found.</td>
</tr>
<tr>
<td><strong>LPOS</strong> / <strong>lpos</strong></td>
<td>Relative character position within the line.</td>
</tr>
<tr>
<td><strong>APOS</strong> / <strong>apos</strong></td>
<td>Absolute character position in the document.</td>
</tr>
<tr>
<td><strong>COL</strong> / <strong>col</strong></td>
<td>Column number where the string was found (CSV-Scope option selected).</td>
</tr>
<tr>
<td><strong>MATCH</strong> / <strong>match</strong></td>
<td>Contains the text of the detected string, in contrast to <code>CAP</code> variables which correspond to capture groups in regex patterns.</td>
</tr>
<tr>
<td><strong>FNAME</strong> / <strong>fname</strong></td>
<td>Filename or window title for new, unsaved files.</td>
</tr>
<tr>
<td><strong>FPATH</strong> / <strong>fpath</strong></td>
<td>Full path including the filename, or empty for new, unsaved files.</td>
</tr>
<tr>
<td><strong>CAP1</strong> / <strong>cap1</strong>, <strong>CAP2</strong> / <strong>cap2</strong>, …</td>
<td>Equivalents to regex capture groups, designed for use in the 'Formula Support' environment. Always strings; use <code>tonum(CAP1)</code> for calculations. Note: Standard counterparts (<code>$1</code>, <code>$2</code>, ...) cannot be used in this environment.</td>
</tr>
</table>
<p><strong>Notes:</strong></p>
<ul>
<li><code>FNAME</code> and <code>FPATH</code> are updated for each file processed by <code>Replace All in All Open Docs</code> and <code>Replace All in Files</code>. This ensures that variables always refer to the file currently being modified.</li>
<li><code>MATCH</code> and <code>CAP</code> variables are always strings. For calculations use <code>tonum(CAP1)</code>; see the <a href="#tonum-behaviour">tonum parsing behaviour</a> table for what it accepts.</li>

<h3 id="varsvariable1value1-variable2value2-">vars({Variable1=Value1, Variable2=Value2, ...})</h3>
<p><strong>Note:</strong> This command was previously named <code>init()</code> and has been renamed to <code>vars()</code>. For compatibility, <code>init()</code> still works.</p>
<p>Initializes custom variables for use in various commands, extending beyond standard variables like <code>CNT</code>, <code>MATCH</code>, <code>CAP1</code>. These variables can carry the status of previous find-and-replace operations to subsequent ones.</p>
<p>Custom variables persist from match to match within a single <strong>'Replace All'</strong> operation and can transfer values between list entries. Each new operation (button click) starts with a fresh state. In multi-file replacements, variables also reset at each <strong>document switch</strong>.</p>
<p><strong>Init usage:</strong> Can be used as an init entry (empty Find) to preload before replacements; not mandatory. See <a href="#preload-variables--helpers">Preload Variables & Helpers</a> for workflow and examples.</p>

<h3 id="lvarsfilepath">lvars(filePath)</h3>
<p>Loads custom variables from an external file. The file specifies variable names and their corresponding values. The loaded variables can then be used throughout the Replace process, similar to how variables defined with <a href="#varsvariable1value1-variable2value2-">vars</a> work.</p>
<p>The parameter <strong>filePath</strong> must specify a valid path to a file. Supported path formats include:</p>
<ul>
<li>Escaped Backslashes: <code>"C:\\path\\to\\file.vars"</code></li>
<li>Forward Slashes: <code>"C:/path/to/file.vars"</code></li>
<li>Long Bracket String: <code>[[C:\path\to\file.vars]]</code></li>
</ul>
<p><strong>File:</strong></p>
<pre><code>-- Local variables remain private
local PATH = [[C:\Data\Projects\]]
-- Only the returned variables are accessible in Replace operations
return {
userName = "Alice",
threshold = 10,
enableFeature = true,
fullPath = PATH .. "dataFile.lkp"

<p><strong>Key Points:</strong></p>
<ul>
<li><strong>Conditional Loading:</strong> Variables can be loaded conditionally by placing <code>lvars()</code> alongside a specific Find pattern. In this case, the variables are only initialized when the pattern matches.</li>
