| 12 * Added functionality for explicit manipulation of variables. | |
| 13 getvar, setvar, isvar can be used to get, set and query variables | |
| 14 in the current Octave scope. | |
| 15 Example: | |
| 16 pytave.setvar("x", 1) | |
| 17 pytave.eval(0,"x += 1") | |
| 18 x = pytave.getvar("x") | |
| 19 | |
| 20 * Added functionality to push/pop anonymous scopes on the Octave call | |
| 21 stack. push_scope and pop_scope are provided to create an anonymous scope | |
| 22 and push it on Octave's call stack, to prevent cluttering other variables if | |
| 23 nested calls to pytave are in effect. | |
| 24 | |
| 25 Example: | |
| 26 pytave.push_scope() | |
| 27 pytave.setvar("x", something) | |
| 28 pytave.eval(0, "... do something with x) | |
| 29 pytave.pop_scope() # wipes out x and restores its previous value, if any | |
| 30 | |
| 31 Of course, for proper safety, try/finally block should be used to ensure the | |
| 32 cleanup. For convenience, a local_scope decorator is provided that encloses a | |
| 33 whole function in a push_scope/try/finally/pop_scope sequence: | |
| 34 | |
| 35 @pytave.local_scope | |
| 36 def my_oct_add(x,y): | |
| 37 pytave.setvar("x",x) | |
| 38 pytave.setvar("y",y) | |
| 39 result, = pytave.eval(1, "x + y") | |
| 40 return result | |
| 41 | |
| 42 this function, when called, will not affect the top-level values of x and y, if | |
| 43 any. | |
| 44 | |
| 45 * The Octave welcome banner is now only displayed if Python is run interactively. | |
| 46 | |
| 47 * {}, "" and '' are now accepted as return values and converted to an empty list/string. | |
