The vast majority of J is taken up by defining builtin functions.
To find where a builtin function is defined, check t.c, which is a
table containing the C function corresponding to every J primitive.
For instance, if we want to look at the code for monad i., we search
for it in t.c and see the line:
/* i. */ pdef(CIOTA, VERB, jtiota, jtindexof,1, RMAX,RMAX);The rows are (Symbol name, part of speech, monad, dyad, monad rank, dyad rank 1, dyad rank 2).
Thus jtiota is the C function which performs monad i.. There are
three parts in its definition:
- An entry in je.h,
extern F1(jtiota);, so that the function can be used in other files (in particular, t.h). - An entry in ja.h,
#define iota(x) jtiota(jt,(x))(some spaces omitted).jtis the structure containing J's state; it is passed between all functions. So that the programmer doesn't have to typejta million times, these definitions are used for every function that has it as an argument. - The actual definition, in this case in v.c. What goes in this function will be described elsewhere.
Because the foreign conjunction has so many cases, its implementation is
split across many files, each having a name that starts with x. The master
function, which can be found with a look in t.c as usual, is jtforeign,
in x.c. This function is itself essentially an extension of t.c, indexed
by left and right argument rather than symbol. The rows and meaning are
the same.
