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