S-expression parser for Python

License: BSD 2-Clause "Simplified" License
sexpdata is a simple S-expression parser/serializer. It has simple load and dump functions like pickle, json or PyYAML module.
>>> from sexpdata import loads, dumps
>>> loads('("a" "b")')
['a', 'b']
>>> print(dumps(['a', 'b']))
("a" "b")You can install sexpdata from PyPI:
pip install sexpdata

how does one convert a symbol to a string? Like:
str(Symbol('App')) -> 'App'
is there a clean way to do this? Currently calling str() on symbol doesn't help and equalities like:
term == 'App'
fail.
Would it be possible to add some kind of debug mode so that each token could be associated with line and column number in the input file?
I'm writing an tool that processes large s-expressions and it would be nice to report the location where a semantic error occurs.
E.g. #'foo
If I read the source code aright, this would be just an additional if branch after the parsing of simple quotes, e.g.
elif c == '#':
c_next = string[i+1] if i + 1 < len(string) else None
if not c_next or c_next != "'": raise ExpectQuoted()
# Proceed to parse the following simple quote
elif c == self.line_comment:
…What do you think?
I have a HUGE file with s-expressions, but it seems that no matter if I use load or loads, the input file is printed to my Python terminal (interactive terminal).
ExpectClosingBracket: Not enough closing brackets. Expected ')' to be the last letter in the sexp. Got: None
Note that sexpdata.loads("(0 ;; (\n)") works
Hi, can we disable '\' before '.' in the result?
>> print(dumps([Symbol('a.c'), Symbol('b')]))
(a\.c b)
I want to get the result a.c b
Thanks,

Accordingly, in order to resolve this issue changes to the way project configuration is carried out. This may be done by listing license under dynamic. The same issue is raised by keywords, which in order to be considered should be inside pyproject.toml and under dynamic.
Would it fit the theme of this package to have infix operators? For example, suppose I want the operator -> to act as an infix operator:
class Implies(Infix):
op = '->'
parse("a -> b -> c") == Infix([Symbol("a"), Symbol("b"), Symbol("c")])
This could be done immediately upon finishing parsing a list, for example.

but if i use pip3 install sexpdata==1.0.0 , i will get no error and installed successful
I want an option to parse float numbers (or atoms that are looking so) as Symbols to distinguish 1.1, 1.10, 1.100 etc.
I would like to be able to load a file like this:
(define (a b c) 5)
(define (d e f) (+ e f))
When I try, I get:
File "/home/jdboyd/.virtualenvs/pypile/lib/python3.3/site-packages/sexpdata.py", line 244, in loads
assert len(obj) == 1 # FIXME: raise an appropriate error
AssertionError
I don't think there is an appropriate error to raise there since I think it should be able to parse that file.
If I patch the code to also export the parse function, I can get the above example file returned as a list like:
[[Symbol('define'), [Symbol('a'), Symbol('b'), Symbol('c')], 5], [Symbol('define'), [Symbol('d'), Symbol('e'), Symbol('f')], [Symbol('+'), Symbol('e'), Symbol('f')]]]This is more useful than the assert. If the assert is important to some users, perhaps it could only be triggered when a single_express kwarg is set?
It is replaced by pyproject.toml, right?
Need to see what implication is for oldest supported pythons.

I need to convert this into original json. is there a function already for this?
Generalized container support. Supporting generators allows reduction of memory usage in dumping large data sets.

nose 1 is discontinued and breaks in 3.10. nose2 is too different.
Not exactly sure what changed, but the root cause of this bug in emacs-jedi appears to be upgrading sexpdata to 0.0.3, so something incompatible must have happened.
It's possible to dump a dict to a symbolic expression:
In [2]: dumps({'a': 1})
Out[2]: '(:a 1)'
Unfortunately, getting a dictionary back is not possible:
In [5]: {'a': 1} == loads(dumps({'a': 1}))
Out[5]: False
The issue here seems to be that the parser doesn't understand that symbols starting with colon are supposed to be keys:
In [6]: loads(dumps({'a': 1}))
Out[6]: [Symbol(':a'), 1]
I tested in Python 3 but Python 2 has the same problem:
In [3]: loads(dumps({'a': 1}))
Out[3]: [Symbol(u':a'), 1]
I was getting the error documented #18 and I wanted to check if it was if my string was a valid s-expression. Is there an automatic tool to check such a thing?
Can we remove the following from Symbol._lisp_quoted_specials?
('.', r'\.')
('#', r'\#')
('?', r'\?')
Removing these 3 only causes one unit test to fail:
self.assert_parse(r'path\.join', Symbol(r'path.join'))
which imo should be this anyways:
self.assert_parse(r'path.join', Symbol(r'path.join'))
I had an unexpected error when parsing a (string) s-expression into a nested array/lists representing the AST. The s-expression comes from (SerAPI https://github.com/ejgallego/coq-serapi), but it looks fine to me:
sexp = b'(Answer 3(ObjList((CoqGoal((fg_goals(((name 3)(ty(App(Ind(((Mutind(MPfile(DirPath((Id Logic)(Id Init)(Id Coq))))(DirPath())(Id eq))0)(Instance())))((Ind(((Mutind(MPfile(DirPath((Id Datatypes)(Id Init)(Id Coq))))(DirPath())(Id bool))0)(Instance())))(App(Const((Constant(MPfile(DirPath((Id Nat)(Id Init)(Id Coq))))(DirPath())(Id odd))(Instance())))((App(Construct((((Mutind(MPfile(DirPath((Id Datatypes)(Id Init)(Id Coq))))(DirPath())(Id nat))0)2)(Instance())))((Construct((((Mutind(MPfile(DirPath((Id Datatypes)(Id Init)(Id Coq))))(DirPath())(Id nat))0)1)(Instance())))))))(Construct((((Mutind(MPfile(DirPath((Id Datatypes)(Id Init)(Id Coq))))(DirPath())(Id bool))0)1)(Instance()))))))(hyp()))))(bg_goals())(shelved_goals())(given_up_goals()))))))\n'

I am curious, what is the difference between this library (https://sexpdata.readthedocs.io/en/latest/) vs using Lark (https://lark-parser.readthedocs.io/en/latest/) for parsing s-expressions?

Does it work? Is it tested? Does it install as a utility when sexpdata is installed?
>>> sexpdata.dumps(sexpdata.loads("(a . b)"))
u'(a \\. b)'
Is there any way to emit a .?
when i use sexpdata to read eeschem-files (like https://github.com/snhobbs/eeschema-script-control does) that include images, then writing this sexpdata back to a new file renders it useless for eeschem (https://www.kicad.org/discover/schematic-capture/).
the problem is, that whiel eeschem puts the image in many lines, the sexpdata.dumps(tree, pretty_print=True) dose not. or in short, the CR and/or LF are missing.
its easy to see in the picture:
top is the original file and bottom is the read into sexpdata and write again file.
pip install sexpdata fails with:
_MissingDynamic: `license` defined outside of `pyproject.toml` is ignored.
This is in python 3.10.13
$ pip install sexpdata

********************************************************************************
The following seems to be defined outside of `pyproject.toml`:
`license = BSD License`
According to the spec (see the link below), however, setuptools CANNOT
consider this value unless `license` is listed as `dynamic`.
https://packaging.python.org/en/latest/specifications/declaring-project-metadata/
To prevent this problem, you can list `license` under `dynamic` or alternatively
remove the `[project]` table from your file and rely entirely on other means of
configuration.
