AutoHotkey has very simple support for error tracking. |
|||
The global ErrorLevel keeps track of the last error. |
|||
Here is one way to keep track of nested errors: |
|||
<lang AutoHotkey>foo() |
|||
return |
|||
foo() |
|||
{ |
|||
bar(0) |
|||
if instr(ErrorLevel, "U0") |
|||
Msgbox caught error: U0 |
|||
bar(1) |
|||
if instr(ErrorLevel, "U0") |
|||
Msgbox caught error: U0 |
|||
} |
|||
bar(i) |
|||
{ |
|||
StringReplace, ErrorLevel, ErrorLevel, baz_error, ,All ; clear baz_error(s) |
|||
if !baz(i) |
|||
ErrorLevel .= "baz_error" ; add baz_error to errorstack |
|||
} |
|||
baz(i) |
|||
{ |
|||
StringReplace, ErrorLevel, ErrorLevel, U1, ,All ; clear U1 errors |
|||
StringReplace, ErrorLevel, ErrorLevel, U0, ,All ; clear U0 errors |
|||
if i |
|||
ErrorLevel .= "U1" ; add U1 errors to errorstack |
|||
Else |
|||
ErrorLevel .= "U0" |
|||
return 1 |
|||
}</lang> |
