Class MCodeExpansionSyntax
- Namespace
- Hi.NcParsers.LogicSyntaxs
- Assembly
- HiMech.dll
Expands machine-declared M-codes (IMCodeDeclarationConfig
on the controller parameter table) into the canonical ISO flags the
regular consumers already understand: tool change → M06, spindle
direction → M03/M04/M05, coolant →
M07/M08/M09. Must run ahead of
SpindleSpeedSyntax, CoolantSyntax, and
ToolChangeSyntax — expanding early is what lets one
composite OEM code (e.g. M13 = spindle CW + flood coolant) feed
several downstream consumers without any of them fighting over who
removes the original flag. Same rewrite-into-shared-vocabulary pattern
as HeidenhainRadiusCompSyntax (RL/RR/R0 →
G41/G42/G40).
Two deliberate boundaries keep the rewrite faithful. Declarations whose
sole content is a spindle direction
(IsSpindleDirectionOnly) are NOT expanded —
SpindleSpeedSyntax resolves them in place via
TryResolveDirection(string, out SpindleDirection), which keeps
legacy <SpindleMCode> configs bit-identical and avoids the
expansion product being re-translated by that same custom-first map
(e.g. a mirrored M03↔M04 remap would otherwise flip direction).
Expansion codes are inserted at the declared flag's own position, and a
code whose raw twin also appears un-declared elsewhere in the block is
not emitted — the block's textual order keeps deciding last-wins
conflicts exactly as it did before.
Declared-but-unmodeled behavior stays loud: a declaration carrying an
UnmodeledNote emits one
DeclaredMCode--UnmodeledEffects informational diagnostic per
occurrence — a declaration replaces the raw Parsing--Unconsumed
warning with an explanation, never with silence. A declaration with no
effects and no note consumes its code silently by explicit intent.
Undeclared codes are untouched and keep falling through to
UnconsumedCheckSyntax.

Examples
Composite OEM code (test declares M13 → spindle CW + flood coolant) — the declared flag is replaced in place by its canonical ISO equivalents; other words ride along untouched: #BeforeBuild:
{ "Parsing": { "Flags": ["M13"], "S": 2000 } }
#AfterBuild:
{ "Parsing": { "Flags": ["M03", "M08"], "S": 2000 } }
Custom tool-change trigger (test declares M106 → tool change, the Siemens $MC_TOOL_CHANGE_M_CODE shape) — expands to M06 for ToolChangeSyntax to consume: #BeforeBuild:
{ "Parsing": { "Flags": ["M106"], "T": 5 } }
#AfterBuild:
{ "Parsing": { "Flags": ["M06"], "T": 5 } }
Note-only declaration (test declares M23 with an unmodeled note and no effects) — consumed with an explanatory diagnostic, leaving the block clean: #BeforeBuild:
{ "Parsing": { "Flags": ["M23"] } }
#AfterBuild:
{}
Undeclared code — untouched, still falls through to the unconsumed check: #BeforeBuild:
{ "Parsing": { "Flags": ["M55"] } }
#AfterBuild:
{ "Parsing": { "Flags": ["M55"] } }
Spindle-direction-only declaration (test declares M203 → CW, nothing else) — deliberately NOT expanded; SpindleSpeedSyntax resolves it in place, keeping legacy configs bit-identical: #BeforeBuild:
{ "Parsing": { "Flags": ["M203"], "S": 1670 } }
#AfterBuild:
{ "Parsing": { "Flags": ["M203"], "S": 1670 } }
In-place expansion keeps textual last-wins order — the composite M13 expands at its own position, so a later raw M05 still overrides the spindle half downstream: #BeforeBuild:
{ "Parsing": { "Flags": ["M13", "M05"] } }
#AfterBuild:
{ "Parsing": { "Flags": ["M03", "M08", "M05"] } }
A canonical target that is itself declared (test declares M08 → note-only) must not swallow the composite's effect: the raw M08 is consumed for its own declaration while M13's flood half still emits M08: #BeforeBuild:
{ "Parsing": { "Flags": ["M13", "M08"] } }
#AfterBuild:
{ "Parsing": { "Flags": ["M03", "M08"] } }
Constructors
MCodeExpansionSyntax()
Initializes a new instance with default settings.
public MCodeExpansionSyntax()
MCodeExpansionSyntax(XElement)
Initializes a new instance by deserializing from the given XML element.
public MCodeExpansionSyntax(XElement src)
Parameters
srcXElementSource XML element.
Fields
UnknownCoolantDiagId
Diagnostic id for a declaration whose CoolantMode names no known mode.
public const string UnknownCoolantDiagId = "DeclaredMCode--UnknownCoolantMode"
Field Value
UnmodeledDiagId
Diagnostic id for the informational message emitted when a consumed declaration carries an UnmodeledNote.
public const string UnmodeledDiagId = "DeclaredMCode--UnmodeledEffects"
Field Value
Properties
Name
Syntax kind name (typically the concrete type name).
public string Name { get; }
Property Value
XName
XML element name used to register this syntax with XFactory.
public static string XName { get; }
Property Value
Methods
Build(LazyLinkedListNode<SyntaxPiece>, List<INcDependency>, NcDiagnosticProgress)
Build syntax arrangement into the
syntaxPieceNode in-place.
public void Build(LazyLinkedListNode<SyntaxPiece> syntaxPieceNode, List<INcDependency> ncDependencyList, NcDiagnosticProgress ncDiagnosticProgress)
Parameters
syntaxPieceNodeLazyLinkedListNode<SyntaxPiece>ncDependencyListList<INcDependency>ncDiagnosticProgressNcDiagnosticProgress
MakeXmlSource(string, string, bool)
Creates an XML representation of the object. This method may also generate additional resources such as related files.
public XElement MakeXmlSource(string baseDirectory, string relFile, bool exhibitionOnly)
Parameters
baseDirectorystringThe base directory for resolving relative paths
relFilestringThe relative file path for the XML source
exhibitionOnlyboolif true, the extended file creation is suppressed.
Returns
- XElement
An XML element representing the object's state
Remarks
For the demand of easy moving source folder (especially project folder) without configuration file path corruption, the relative file path is applied.
The baseDirectory is typically the folder at the nearest configuration file folder.
Since the folder can be moving with the configuration file.
Reg(XFactory)
Registers this type's deserializer with the given XFactory
(or Default when factory is
null). Idempotent.
public static void Reg(XFactory factory = null)
Parameters
