The original motivation is to fix the new (= nil ()) and
core_apply_accepts_macros tests.
Improve speed and warnings with byte compilation.
mal/core.el:
Wrap core functions during the loop in main, instead of writing the
conversion in each line of core-ns.
Use apply built-in concatenation of last argument.
Move handling of metadata to types.el.
mal/env.el:
Represent environments as cons cells instead of vectors.
mal/func.el:
Merged into types.el, it is not a special case anymore.
mal/printer.el:
Add macro case.
Define a pr-join helper for sequences and core.el.
mal/reader.el:
Rename the tokens local variable in reader.el (compiler warning).
mal/types.el:
Use type-specific accessors returning nil for the wrong type
(structural pattern matching would be better, but is too slow).
Represent native types directly when possible, and inline some trivial
accessors.
Use dedicated records instead of vectors.
Implement metadata only when required.
Represent keywords as strings (easyer, no counterpart).
run:
Run byte-compiled version.
steps:
Backport good ideas from stepA to step1, reducing the diff between
steps for future maintenance.
Implement 'do with a simple iteration (without map and butlast).
Make the repl-env local to main (compiler warning).
Make the code more idiomatic
* prefer loop over recursion (search in environments)
* declare variable and reassign them when convenient (exit of the TCO loop)
* car cdr cadr and so on instead of nth
* remove various vector <-> list conversions.
- Add a `vec` built-in function in step7 so that `quasiquote` does not
require `apply` from step9.
- Introduce quasiquoteexpand special in order to help debugging step7.
This may also prepare newcomers to understand step8.
- Add soft tests.
- Do not quote numbers, strings and so on.
Should ideally have been in separate commits:
- elisp: simplify and fix (keyword :k)
- factor: fix copy/paste error in let*/step7, simplify eval-ast.
- guile: improve list/vector types
- haskell: revert evaluation during quasiquote
- logo, make: cosmetic issues
- Reorder README to have implementation list after "learning tool"
bullet.
- This also moves tests/ and libs/ into impls. It would be preferrable
to have these directories at the top level. However, this causes
difficulties with the wasm implementations which need pre-open
directories and have trouble with paths starting with "../../". So
in lieu of that, symlink those directories to the top-level.
- Move the run_argv_test.sh script into the tests directory for
general hygiene.
