Parser is used for both parsing and evaluating smalltalk expressions; |
|
86 |
it first builds a parseTree which is then interpreted (evaluate) or |
|
87 |
compiled. Compilation is done in the subclass ByteCodeCompiler and/or |
|
88 |
the (planned) MachineCodeCompiler. |

and: |

Parser parseExpression:... |

Parser parseMethod:... |
|
19 | 96 |
|
97 |
there is protocol to parse complete methods, selector specs, body only etc. |
|
98 |
||
99 |
Parser is also used to find the referenced/modified inst/classvars of |
|
100 |
a method - this is done by sending parseXXX message to a parser and asking |
|
101 |
the parser for referencedXVars or modifiedXVars (see SystemBrowser). |
|
102 |
||
103 |
You can also use parsers for all kinds of other things (ChangesBrowser for |
|
104 |
example analyzes the expressions in the changelist ...) by looking at the |
|
105 |
parsers tree. (Although this is somewhat dangerous, since it exports the |
|
755 | 106 |
compilers internals ... better style is to add specialized query methods here) |
19 | 107 |
|
108 |
One instance of Parser is created to parse one method or expression - i.e. |
|
109 |
its not suggested to reuse parsers. |

Therefore, this mode is a bit dangerous and disabled by default. |
755 | 124 |
The current implementation, base upon a global constant-folding setting is somewhat stupid |
125 |
and intermediate - a better solution would be to allow the optimization to be controlled |
|
126 |
by a method-pragma, since it may make sense to disable optimization on a method level, |
|
127 |
if its known that the used constant objects are subject of modifications as described above. |
