<meta name="description" content="Shared polymorphic reader for Fanuc Custom Macro B conditional gate expressions (IF [...] GOTO, IF [...] THEN, WHILE [...] DO m). The condition node is read post-evaluation — 's pass-2 tree walk has already substituted the original expression string with a numeric when evaluation succeeded; this helper maps that node to a tri-state truthy outcome plus a display form for diagnostics. Three states, mapping directly to the ConditionEvaluated: true | false | null stamp shape used by all three consumers (see , , and the WHILE-loop syntax): Truthy = true — node is a finite non-zero numeric; gate fires.Truthy = false — node is a finite numeric equal to zero; gate falls through silently.Truthy = null — node is null, still a string (evaluator failed), or non-finite double (NaN / ±∞); gate falls through and the caller emits its own &lt;Syntax&gt;--ConditionNotEvaluated warning. The Display form is the human-readable expression text for diagnostic messages. For resolved numerics it is the value formatted via ; for unresolved strings it is the original expression text. Diagnostics build their own message text — the helper just provides the source string so the caller can compose "IF [&lt;Display&gt;] GOTO ..." etc. Callers typically the original node before passing in here, then again before stamping back, so removing the parsing section and writing the host-level stamp can happen in any order without dangling references.">

|
|
<a class="xref" href="Hi.NcParsers.EvaluationSyntaxs.VariableEvaluatorSyntax.html">VariableEvaluatorSyntax</a>'s pass-2 tree walk has already

|
substituted the original expression string with a numeric
|

<a class="xref" href="https://learn.microsoft.com/dotnet/api/system.text.json.nodes.jsonvalue">JsonValue</a> when evaluation succeeded; this helper maps
|
|
that node to a tri-state truthy outcome plus a display form for
|
|
diagnostics.</p>
|
|
<p>
|
|
Three states, mapping directly to the
|
|
<code>ConditionEvaluated: true | false | null</code> stamp shape used by
|
|
all three consumers (see <a class="xref" href="Hi.NcParsers.EvaluationSyntaxs.Fanuc.FanucGotoSyntax.html">FanucGotoSyntax</a>,
|
|
<a class="xref" href="Hi.NcParsers.EvaluationSyntaxs.Fanuc.FanucIfThenSyntax.html">FanucIfThenSyntax</a>, and the WHILE-loop syntax):
|
|
</p>
|
|
<ul><li><b>Truthy = true</b> — node is a finite non-zero numeric;
|
|
gate fires.</li><li><b>Truthy = false</b> — node is a finite numeric equal to
|
|
zero; gate falls through silently.</li><li><b>Truthy = null</b> — node is null, still a string
|
|
(evaluator failed), or non-finite double (NaN / ±∞); gate falls
|
|
through and the caller emits its own
|
|
<code><Syntax>--ConditionNotEvaluated</code> warning.</li></ul>
|
|
<p>
|
|
The <code>Display</code> form is the human-readable expression text for
|
|
diagnostic messages. For resolved numerics it is the value formatted
|
|
via <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.globalization.cultureinfo.invariantculture">InvariantCulture</a>; for unresolved
|
|
strings it is the original expression text. Diagnostics build their
|
|
own message text — the helper just provides the source string so the
|
|
caller can compose <code>"IF [<Display>] GOTO ..."</code> etc.
|
|
</p>
|
|
<p>
|
|
Callers typically <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.text.json.nodes.jsonnode.deepclone">DeepClone()</a> the original node
|
|
before passing in here, then again before stamping back, so removing

|
the parsing section and writing the host-level stamp can happen in
|
|
any order without dangling references.
