Most PRs are either rejected (if there is a techincal flaw) or accepted within a day, so send an improvement our way and see what happens. +We have a very open contribution process. If you have a feature you'd like to implement, submit a PR or file an issue and we'll see what we can do. Most PRs are either rejected (if there is a technical flaw) or accepted within a day, so send an improvement our way and see what happens. ## Implementation Notes Although parts of the language may be very close to Clojure (they are both lisps after all), language parity is not a design goal. We will take the features from Clojure or other languages that are suitable to our needs, and feel free to reject those that aren't. Therefore this should not be considered a "Clojure Dialect", but instead a "Clojure inspired lisp". ## Disclaimer -This project is the personal work of Timothy Baldridge and contributors.

To fix this I changed the semantics of `read` to allow it to not return a form at all (signalled by returning the reader itself, as in https://github.com/clojure/tools.reader), for situations like `;`. Unsure if this is the best approach to fixing, open to discussion. Another option could be to treat comments as whitespace. Also, the reader tests had some cases where they wouldn't verify the input properly, so I fixed those as well. --- pixie/vm/reader.py | 34 +++++++++++++++++++++------------- pixie/vm/test/test_reader.py | 20 ++++++++++++++++++-- 2 files changed, 39 insertions(+), 15 deletions(-) diff --git a/pixie/vm/reader.py b/pixie/vm/reader.py index 3049ae2f..fedb558b 100644 --- a/pixie/vm/reader.py +++ b/pixie/vm/reader.py @@ -221,7 +221,9 @@ def invoke(self, rdr, ch): return acc rdr.unread(ch) - lst.append(read(rdr, True)) + itm = read(rdr, True, always_return_form=False) + if itm != rdr: + lst.append(itm) class UnmatchedListReader(ReaderHandler): def invoke(self, rdr, ch): @@ -237,7 +239,9 @@ def invoke(self, rdr, ch): return acc rdr.unread(ch) - acc = rt.conj(acc, read(rdr, True)) + itm = read(rdr, True, always_return_form=False) + if itm != rdr: + acc = rt.conj(acc, itm) class UnmatchedVectorReader(ReaderHandler): def invoke(self, rdr, ch): @@ -253,9 +257,14 @@ def invoke(self, rdr, ch): return acc rdr.unread(ch) - k = read(rdr, True) - v = read(rdr, False) - acc = rt._assoc(acc, k, v) + itm = read(rdr, True, always_return_form=False) + if itm != rdr: + k = itm + itm = rdr + while itm == rdr: + itm = read(rdr, False, always_return_form=False) + v = itm + acc = rt._assoc(acc, k, v) return acc class UnmatchedMapReader(ReaderHandler): @@ -573,17 +582,13 @@ def invoke(self, rdr, ch): class LineCommentReader(ReaderHandler): def invoke(self, rdr, ch): self.skip_line(rdr) - return read(rdr, True) + return rdr def skip_line(self, rdr): while True: ch = rdr.read() if ch == u"\n": return - elif ch == u"\r": - ch2 = rdr.read() - if ch2 == u"\n": - return handlers = {u"(": ListReader(), u")": UnmatchedListReader(), @@ -723,7 +728,7 @@ def throw_syntax_error_with_data(rdr, txt): -def read(rdr, error_on_eof): +def read(rdr, error_on_eof, always_return_form=True): try: eat_whitespace(rdr) except EOFError as ex: @@ -742,6 +747,8 @@ def read(rdr, error_on_eof): macro = handlers.get(ch, None) if macro is not None: itm = macro.invoke(rdr, ch) + if always_return_form and itm == rdr: + return read(rdr, error_on_eof, always_return_form=always_return_form) elif is_digit(ch): itm = read_number(rdr, ch) @@ -759,8 +766,9 @@ def read(rdr, error_on_eof): else: itm = read_symbol(rdr, ch) - if rt.has_meta_QMARK_(itm): - itm = rt.with_meta(itm, rt.merge(meta, rt.meta(itm))) + if itm != rdr: + if rt.has_meta_QMARK_(itm): + itm = rt.with_meta(itm, rt.merge(meta, rt.meta(itm))) return itm diff --git a/pixie/vm/test/test_reader.py b/pixie/vm/test/test_reader.py index 33a08152..19539f0c 100644 --- a/pixie/vm/test/test_reader.py +++ b/pixie/vm/test/test_reader.py @@ -4,6 +4,8 @@ from pixie.vm.numbers import Integer from pixie.vm.symbol import symbol, Symbol from pixie.vm.persistent_vector import PersistentVector +from pixie.vm.persistent_hash_map import PersistentHashMap +from pixie.vm.primitives import nil import pixie.vm.rt as rt import unittest @@ -17,7 +19,14 @@ u"(platform+ 1 2)": (symbol(u"platform+"), 1, 2), u"[42 43 44]": [42, 43, 44], u"(1 2 ; 7 8 9\n3)": (1, 2, 3,), - u"(1 2 ; 7 8 9\r\n3)": (1, 2, 3,)} + u"(1 2 ; 7 8 9\r\n3)": (1, 2, 3,), + u"(1 2 ; 7 8 9\r\n)": (1, 2,), + u"(1 2 ; 7 8 9\n)": (1, 2,), + u"[1 2 ; 7 8 9\n]": [1, 2,], + u"(1 2; 7 8 9\n)": (1, 2,), + u";foo\n(1 2; 7 8 9\n)": (1, 2,), + u"{\"foo\" 1 ;\"bar\" 2\n\"baz\" 3}": {"foo": 1, "baz": 3}, + u"{\"foo\" ; \"bar\" 2\n1 \"baz\" 3}": {"foo": 1, "baz": 3}} class TestReader(unittest.TestCase): def _compare(self, frm, to): @@ -27,6 +36,7 @@ def _compare(self, frm, to): for x in to: self._compare(frm.first(), x) frm = frm.next() + assert frm == nil elif isinstance(to, int): assert isinstance(frm, Integer) assert frm._int_val == to @@ -38,9 +48,15 @@ def _compare(self, frm, to): elif isinstance(to, list): assert isinstance(frm, PersistentVector) - for x in range(len(to)): + for x in range(max(len(to), rt._count(frm)._int_val)): self._compare(rt.nth(frm, rt.wrap(x)), to[x]) + elif isinstance(to, dict): + assert isinstance(frm, PersistentHashMap) + for key in dict.keys(to): + self._compare(frm.val_at(rt.wrap(key), ""), to[key]) + + assert rt._count(frm)._int_val == len(dict.keys(to)) else: raise Exception("Don't know how to handle " + str(type(to))) From ddbc00dd1e523eba0e6a7111202f48ce489fe839 Mon Sep 17 00:00:00 2001 From: Justin Jaffray Date: Sat, 14 Mar 2015 14:59:00 +0000 Subject: [PATCH 292/612] Allow macro characters as character literals Previously ``` (def a \)) ``` would fail to parse.

The implementation and the tests were imported and adapted from Clojure's standard library (from [1] and [2], respectively). Since Clojure's implementation uses it, the function `completing` was imported as well (from the same source). As of now, Pixie's stdlib lacks a `sort`/`sort-by` function, one of the tests is disabled (commented out), and another is modified in order to avoid the call to `sort-by`. Sources: Both from Clojure's main repo, fetched at commit `3b98a00`.

This was modifying the reducing function passed to the transducer, causing reduced values to be wrapped in `reduced` twice, so the reducing process wasn't completely unwrapping reduced values when finishing. Reducing functions only need to be wrapped with `preserving-reduced` if they call `reduce` themselves. (Like `cat` and `pixie.io.common/stream-reducer`) Also fixes a problem with the `take` transducer consuming one more element than needed.
