In FriCAS the word ## Adding new algebra in FriCASThe process of adding new algebra to FriCAS is considerable different from Axiom and OpenAxiom. FriCAS no longer uses the old Lisp bootstrap method. Instead the build proceeds directly from the SPAD source code in several phases. The dependencies between SPAD modules are no longer so critical and build process should handle them automatically. To add new algebra code you need: 1) Create a new file(s) and and it to the SPAD_SRCS variable in src/algebra/Makefile.in. This step is not needed if you are adding code to an already existing file. 2) Add the constructor(s) (more precisely its abbreviation(s)) to apropriate SPADLIST variable in src/algebra/Makefile.in. To assist parallel build abbreviations are divided between several variables, in lexicographic order. 3) If you are adding a category and it to the CATLIST variable in src/algebra/Makefile.in 4) If you are adding category with default implementation add it to the CATDOMS variable in src/algebra/Makefile.in 5) If you are adding a domain which should be subject to inlining optimization
add it to DOMLIST variable in src/algebra/Makefile.in (to activate inlining
you also need to add it to Rebuilding the algebra from scratch Historically building algebra was a compilcated process. FriCAS has special support to simplify it. Basic idea is that once declarations of constructors and exported functions are known we can compile implementation parts in any order. FriCAS contains special function which performs first part of algebra build collecting informations about constructors. There is an extra complication because we want inlining optimization: calls to simple function in a few core domains are replaced by function bodies. Fortunately all this is handled by the algbera Makefile and to add new constructor it is enough to follow instructions above. Note: FriCAS algebra is build from scratch during full build. However
release tarball contains partially compiled machine independent files,
which saves build time, but means that actual Spad files are not used.
