* Improve dumpLisp macro
- Remove commas from the lisp representation of the AST.
- Make the dumpLisp output "pretty" and indented.
- Improve docs of `dumpTree` and `dumpLisp` macros.
With:
dumpLisp:
echo "Hello, World!"
Output before this commit:
StmtList(Command(Ident("echo"), StrLit("Hello, World!")))
Output after this commit:
(StmtList
(Command
(Ident "echo")
(StrLit "Hello, World!")))
* Re-use the traverse proc inside treeRepr for lispRepr too
- Add module-local `treeTraverse` proc.
- Also fix treeRepr/dumpTree not printing nnkCommentStmt node contents.
* More doc string updates
* Allow unindented lispRepr output for tests
* Update a test affected by the lispRepr change
* Fix dumpTree
* Add note about lispRepr and dumpLisp to changelog [ci skip]
* fixes#8916 by removing `tyString`, `tySeq`, mod. marshal, typeinfo
Need to check in `typeinfo` for nil of the underlying pointer.
In marshal don't have to check for nil of seq anymore.
* remove reference to string, sequence in `isNil` doc string
* bindSym power up, working prototype
* update bindSym doc
* add bindSym test
* fix some typo
* fix bindSym doc
* get rid of specialops field from vm
* add experimental: dynamicBindSym
This allows you to pass a template or a macro to another macro
which can then inspect the implementation of the former template/macro
using `getImpl`.
Since templates can be freely redefined, this allows you to treat
their symbols as compile-time variables that have lexical scope.
A motivating PoC example for a logging library taking advantage of
this will be provided in the next commit.
Implementation details:
* The name of a template or a macro will be consider a symbol if
the template/macro requires parameters
* For parameterless templates/macros, you can use `bindSym`, which
was extended to also work outside of compile-time procs.
* Added codeRepr and dumpCode to the macros module.
This allows those writing macros to write examples, get the code to generate the AST for that example, and then modify that code to be dynamic with the macro function.
