- Expose `read`, `read_str`, and `eval` in Python
- Add string evaluation example to interop section of docs
- Add test for `eval`
- Explain `eof` keyword argument in `read` docstring
The implementation of `hy.core.language.exec` draws code from the `exec_` function in commit f574c7be6ebc80041ef58ca29588f310248ebed4 of the library Six, which is copyright 2010–2017 Benjamin Peterson and licensed under the Expat license.
This is no longer necessary now that `defn` always produces a `FunctionDef`.
To compensate, I've made small edits to two contrib modules and reverted a small test change.
* Remove uses of `car` and `cdr` in /hy
* Remove uses of `car` and `cdr` in quote tests
* Remove `car` and `cdr` in favor of `first` and `rest`
I beefed up the documentation and tests for `first` and `rest` while I was at it.
I defined `car` and `cdr` in native_tests.cons so the tests read a bit more naturally.
* with-decorator: Allow a `setv` form as the form to be decorated
This feature is of dubious value by itself, but it's necessary to allow `defn` to create a lambda instead of a `def`.
* Make `fn` work the same as `lambda`
That is, allow it to generate a `lambda` instead of a `def` statement if the function body is just an expression.
I've removed two uses of with_decorator in hy.compiler because they'd require adding another case to HyASTCompiler.compile_decorate_expression and they have no ultimate effect, anyway.
In a few tests, I've added a meaningless statement in `fn` bodies to force generation of a `def`.
I've removed `test_fn_compiler_empty_function` rather than rewrite it because it seems like a pain to maintain and not very useful.
* Remove `lambda`, now that `fn` does the same thing
You can use them as thousands separators.
This change differs from PEP 515 in that not only does it allow commas in addition to underscores, but it's much more liberal about placement. Any number of underscores or commas can be placed anywhere, even at the start.
* Docs: Hy <-> Python interop fix#1061
I separated the existing text in two sections, with some additional
explanations and a link to Hy's `import`.
* added interop page
* simplified interop section in tutorial
* remove the TODO from interop section in tutorial
Because yay
* Corrections from @Kodiologist
I kept the part about mangling, but added a warning about its incompleteness. I
think it can be useful for somebody who just wants to use a Python module in his
code. Maybe it can be removed when the actual documentation for mangling is
written.
* Added myself to AUTHORS.
I'll do my best to be worthy of it. Thanks for this awesome project!
* Add comp, constantly and complement
relates #1176
* Fix composition order in comp
* comp without parameters returns identity
* Doc edits for comp, complement, constantly
* Test that `(comp)` returns `identity` exactly
* Simplify the `reduce` call in `comp`
* updated version of comp
* added defmacro!
* revert #924#924 had an error and should never have been merged in the first place. (see #903)
* put back import getargspec
Without the `formatargspec` this time.
* Give better error message on failed macro expansion
Better error messages work most of the time. In cases where there are
parameters that aren't valid in Python, error message shown is rather
ugly. But this is better than no error messages at all and such
macros with strange parameter names are rather rare.
* fix flake8 errors
* Minor English improvements
