b7742c6b | 74 | - eval (exp, env) |
89bff2fc | 75 | |
b7742c6b AW |
76 | evaluates EXP in environment ENV. ENV is a lexical environment |
77 | structure as used by the actual tree code evaluator. When ENV is | |
78 | a top-level environment, then changes to the current module are | |
79 | tracked by updating ENV so that it continues to be in sync with | |
80 | the current module. | |
e6729603 | 81 | |
b7742c6b | 82 | - scm_primitive_eval (exp) |
e6729603 | 83 | |
b7742c6b AW |
84 | evaluates EXP in the top-level environment as determined by the |
85 | current module. This is done by constructing a suitable | |
86 | environment and calling eval. Thus, changes to the | |
87 | top-level module are tracked normally. | |
e6729603 | 88 | |
b7742c6b | 89 | - scm_eval (exp, mod) |
e6729603 | 90 | |
b7742c6b AW |
91 | evaluates EXP while MOD is the current module. This is done |
92 | by setting the current module to MOD_OR_STATE, invoking | |
93 | scm_primitive_eval on EXP, and then restoring the current module | |
94 | to the value it had previously. That is, while EXP is evaluated, | |
95 | changes to the current module (or dynamic state) are tracked, | |
96 | but these changes do not persist when scm_eval returns. | |
