Attributes

• Pin numbers (which are attributes) should all be 8 pt in size.
• Attached attributes should be yellow. The color is set automatically to yellow if the text item is attached.
• The only exception to this is pinlabel= attributes, those should be color number 9 (text | green). If every text item within a symbol is yellow, the symbol looks too yellow.
• Attributes can be attached to some part of the symbol. Toplevel attributes (like the device= or net= attributes) used to be required to be attached to something to be attributes, but now they just have to exist in the symbol file as name=value.
• Expanding a bit on the last sentence, as long as the text item has the format name=value, it is considered an attribute. Attributes inside a symbol do not have to be attached to anything. In order to see hidden attributes in gschem select Edit/Show/Hide Inv Text.
• There is a symbol content versioning system in libgeda which is based on the symversion= attribute. Please see the Master Attribute Document for more information on using this versioning scheme.
