Yes, the goal was the control flow of the program.
Yeah, looking more at what `PNode` tree contains, I see that it is really just
syntax. (The `if` statement `PNode` contains things like `nkIdent` ":".) I need
the _semantic [tree](https://forum.nim-lang.org/postActivity.xml#tree) of the
code. B
Unfortunately, the new URL leads to few information on the compiler
architecture for a user like I am. My idea was to use Nim's first-class
meta-programming features to plot simple control flow graphs.

Aha, I just had to install `nimble install compiler`. Otherwise it did not find
the package `compiler/parser`:
$ cat parse_nimcode.nim
import compiler/parser
...
$ nim c -r parse_nimcode.nim
Hint: used config file '/.../.local/nim/config/nim.cfg' [Conf]
Hint:
OK, this works:
import compiler/parser
import compiler/idents
import compiler/options
let
code_string: string = "echo \"Hello world!\""
let
code_ident = IdentCache()
code_conf = ConfigRef()
code_ast = parseString(code_string, code_ide
can I revive this question? How to import [the compiler parser
module](https://nim-lang.org/docs/intern.html#the-compiler-s-architecture) and
its procs in nim 2.0? E.g.
[parseString()](https://nim-lang.org/docs/compiler/parser.html#parseString%2Cstring%2CIdentCache%2CConfigRef%2Cstring%2Cint%2CE
Thanks for the links!
I think it may actually be a good idiom to declare dummy nodes and delete them
in the macro. The dummy nodes can serve as a demo for other developers of what
you intend to do in the macro.
It looks like `newEnum` also requires the enum to have at least one field:
macro ... =
enumDef = newEnum(`enumName`, [], true, true)
$ nim c -r -d:release basic_macro.nim
...
/.../.local/nim/lib/core/macros.nim(1272, 10) Error: Enum must contain at
least one fi
I would like to generate an enum and a matching array of strings in a macro, as
in [this
example](https://peterme.net/metaprogramming-and-read-and-maintainability-in-nim.html)
but with `quote` [instead of direct tree
nodes](https://gist.github.com/xealits/2c7f1468cff736c129b251317aa2bbda) like
