| :: call do_foo |
| :: if [expression] ( |
| :: call cmd_a |
| :: set my_var = %ERRORLEVEL% |
| :: call final_script --flag %my_var% |
| :: ) |
| :: Batch evaluates these expressions in a way that will produce unexpected |
| :: behavior. It appears that when each line is executed, it does not affect |
| :: local context until the entire expression is complete. In this example, |
| :: ERRORLEVEL does not reflect `call cmd_a`, but whatever residual state was |
| :: present from `do_foo`. Similarly, in the call to `final_script`, `my_var` |
| :: will NOT be valid as the variable `set` doesn't apply until the entire `if` |
| :: expression completes. |
| :: This script only uses multi-line if statements to `goto` after an operation. |
| |
| :: If PW_CHECKOUT_ROOT is set, use it. Users should not set this variable. |
| :: It's used because when one batch script invokes another the Powershell magic |
| :: below doesn't work. To reinforce that users should not be using |
| :: PW_CHECKOUT_ROOT, it is cleared here after it is used, and other pw tools |
| :: will complain if they see that variable set. |
