Class SlicerMetadataParserAbstract

constructor

• new SlicerMetadataParser(): SlicerMetadataParser

  Returns SlicerMetadataParser

canParse

• canParse(commentCommands: GCodeCommand[], maxLines?: number): boolean

  Checks if this parser can handle the given gcode based on comments

  Parameters

  • commentCommands: GCodeCommand[]

    Array of gcode commands with comments
  • maxLines: number = 200

    How many of those commands to sample before giving up

  Returns boolean

  True if this parser can handle the gcode

derivesExtrusionDimensions

• derivesExtrusionDimensions(commentCommands: GCodeCommand[]): boolean

  Whether the moves of this gcode can be trusted to derive per-path extrusion dimensions from

  Parameters

  • commentCommands: GCodeCommand[]

    Array of gcode commands with comments

  Returns boolean

  True unless the dialect's E values are not filament lengths

  Remarks

  Deriving is the default, for every dialect and for gcode no parser recognised: a file that announces its dimensions simply outranks the derived values path by path (the Job resolves that order), so there is nothing to gate on. A dialect only opts out when the arithmetic itself does not hold -- Cura's UltiGCode flavor, whose E is cubic millimetres of material rather than millimetres of filament, would otherwise derive confidently wrong widths. Evaluated on the chunk that identified the slicer (like detectSlicerName), so it can inspect header comments.

detectSlicerName

• detectSlicerName(commentCommands: GCodeCommand[]): string

  Resolves the slicer name to report for the given gcode.

  Parameters

  • commentCommands: GCodeCommand[]

    Array of gcode commands with comments

  Returns string

  The slicer name

  Remarks

  Parsers that handle a family of slicers sharing one comment dialect override this to report the specific generator named in the header.

parseExtrusionDimensions

• parseExtrusionDimensions(commands: GCodeCommand[]): ExtrusionDimensionMetadata[]

  Parses extrusion dimension changes from gcode comments

  Parameters

  • commands: GCodeCommand[]

    Array of gcode commands with comments

  Returns ExtrusionDimensionMetadata[]

  Dimension change events extracted from comments, in line order

  Remarks

  Only dialects that announce per-path dimensions override this; the default reports none.

parseFilamentDiameter

• parseFilamentDiameter(commentCommands: GCodeCommand[]): number

  Reads the filament diameter announced in header comments, when any

  Parameters

  • commentCommands: GCodeCommand[]

    Array of gcode commands with comments

  Returns number

  The filament diameter in millimeters, or undefined when unknown

  Remarks

  Feeds the volumetric dimension derivation (see derivesExtrusionDimensions), which converts extruded filament lengths into deposited volume. Only header-borne values may be reported here: a diameter that appears after moves (like Cura's end-of-file ;SETTING_3 blob) would reach a one-shot parse before any move executes but a streamed parse only after every move already ran, making the two disagree.

AbstractparseLayerMetadata

• parseLayerMetadata(commands: GCodeCommand[]): LayerMetadata[]

  Parses layer metadata from gcode comments

  Parameters

  • commands: GCodeCommand[]

    Array of gcode commands with comments

  Returns LayerMetadata[]

  Layer metadata extracted from comments
