- implement blocks
|
|
* every block has to have its own identifier list. Additional
|
|
a reference to to the upper block should be part of a block
|
|
to realize variable lookup in upper blocks.
|
|
* every block contains a statement list, that hold all statements
|
|
that occured within the block.
|
|
* a block is as itself a statement, that could be part of a statement
|
|
list.
|
|
* blocklocal, global and parent variables
|
|
variables in general are block local. This means, using varable a
|
|
within a sub-block does not affect an existing variable a within a
|
|
parent block.
|
|
Every block can contain one optional globals declaration section. This
|
|
is a special block, wich declares identifiers to be used as global
|
|
(topmost block) identifiers. If a non-existent identifier is deklared
|
|
in such a section a global variable is created.
|
|
Additionally there will be a _parent_ operator for use with an identifier.
|
|
This will allow one to access a variable used (and therefor deklared)
|
|
somewhere above the local block. If no variable with this identifier can
|
|
be found an error message is shown and processing will stop.
|
|
|
|
- implement loops and conditionals
|
|
* first the statement directly following the loop or conditional
|
|
tokens is saved.
|
|
* the this is executed 0..n times depending on the loop or conditional.

- ich habe herausgefunden das alle Ausdrücken in denen Variablen vorkommen
|
|
auch in einen statement stack aufgenommen werden müssen. Nur konstante
|
|
Ausdrücken können direkt ausgewertet werden und muessen nicht in
|
|
den AST (abstract statement tree, ist faktisch aber eher ein stack da
|
|
jeder branch unmittelbar ausgeführt wird). Ups, sorry this is
|
|
accidently german.
|
|
|
|
- Add an interface to access the variable space of the interpreter from

|
|
- write a first test-webapp.
|
|
|
|

|
|
|
|
- comment the code more completely.
|
|
|
|
