Support indention for the Func* visualizers #227

Closed wixette closed 2 years ago

wixette commented 2 years ago

Add indention to SeedLang.Shell for the FuncCalled and FuncReturend visualizers, so that the function call stack in the runtime can be displayed clearly.

For example, use SeedLang.Shell to show the call stack of the Tower of Hanoi algorithm:

dotnet run --project src/SeedLang.Shell -- -f ../example_scripts/seedpython/hanoi.py -v "Func*"
SeedLang.Shell 0.2.1-preview20220728155708

Enabled Visualizers: FuncCalled, FuncReturned

---------- Source ----------
1     def move(n, source, target, auxiliary):
2         if n <= 0:
3             return
4         move(n - 1, source, auxiliary, target)
5         print('Tower ' + source + ' -> Tower ' + target)
6         move(n-1, auxiliary, target, source)
7     
8     
9     num = 3
10    move(num, 'A', 'B', 'C')
