* add custom pragma support for var and let symbols
* updated changelog for custom pragmas on var and let symbols
* add oldast switch for backwards compatibility
* 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.
