This test illustrates some features of `debugutils` to debug the compiler.
|
|
|
|
## example
|
|
this shows how to enable compiler logging just for a section of user code,
|
|
without generating tons of unrelated log messages for code you're not interested
|
|
in debugging.
|
|
|
|
```sh
|
|
# enable some debugging code, e.g. the `when false:` block in `semExpr`
|
|
nim c -o:bin/nim_temp --stacktrace -d:debug -d:nimDebugUtils compiler/nim
|
|
bin/nim_temp c tests/compiler/tdebugutils.nim
|
|
```
|
|
|
|
(use --filenames:abs for abs files)
|
|
|
|
## result
|
|
