l3­pack­ages – High-level 3 con­cepts

This col­lec­tion con­tains im­ple­men­ta­tions for as­pects of the 3 ker­nel, deal­ing with higher-level ideas such as the De­signer In­ter­face. The pack­ages here are con­sid­ered broadly sta­ble (The 3 Project does not ex­pect the in­ter­faces to al­ter rad­i­cally). Th­ese pack­ages are built on con­ven­tions at the in­ter­face level, and so may not mi­grate in the cur­rent form to a stand-alone 3 for­mat.

Pack­ages pro­vided:

  • xparse, which pro­vides a high-level in­ter­face for declar­ing doc­u­ment com­mands
  • xfp, an ex­pand­able IEEE 754 FPU for
  • l3keys2e, which makes the fa­cil­i­ties of the ker­nel mod­ule l3keys avail­able for use by 2e pack­ages
  • xtem­plate, which pro­vides a means of defin­ing generic func­tions us­ing a key-value syn­tax
  • xfrac, which pro­vides flex­i­ble split-level frac­tions
