- Fixed -- an issue with hops/property ordering. See -- #53
- Added -- the ability to define custom quotes for labels, properties, and map_keys
import pyper
pyper.builder.QUOTES['propery'] = '"' # this will quote properties with a " instead of `
- Fixed -- removed an unused
hashable import to make Pypher python 3.10 compatable. Thanks Peter Bábics (@pbabics)
- Fixed -- no longer binding python values of
True and False, they will return true and false in the resulting cypher.
- Added
max as a predefined function
- Added
create_statement and create_function to the tester
- Added a new param called
hops for specifying a single hop number.min_hops and max_hops are reserved for specifying variable length relationships. If hops is specified, and one (or both) of min_hops and max_hops is specified, an error is raised. If just one of min_hops or max_hops is specified, then the range is only bounded on that side.
- Fixed an issue with the interactive tester where defining a custom
Func or Statement inline would throw an already registered error
- Fixed an error where custom
Func or Statement sub-classed classes were not properly referenced when building out the final Pypher object.
- Bitwise operators that compile down to apoc calls
BANDBORBXORBNOTBLSHIFTBRSHIFTBULSHIFT
- Fixed an issue where calling
.re() for regular expresson matching, will bind its passed in params.
- Fixed an issue where calling
.append() on an empty Pypher instance did not work as expected.
- Fixed the output from doing a not equal comparison between Pypher objects. It used to result to
!= which is invalid Cypher, now it results in <>
p = Pypher()
p2 = Pypher()
p.a != p2.b
str(p) # a != b
# after 0.16.2
str(p) # a <> b
- Setting
None as values did not result in the keyword NULL, but a string of 'null'.
- Support for allowing
Pypher instances as values in Param instances.
p = Pypher()
val = 'some value'
name = 'name'
p.MATCH.node('p', 'person', lastname=__.coalesce(name, val))
str(p) # MATCH (p:`person` {`lastname`: coalesce($NEO_06c97_0, $NEO_06c97_1)})
Pypher.link() method that will shortcut the process of adding a dynamically named object to the Pypher instance.
p = Pypher()
x = 'mark'
# the old ways
getattr(p, x).__location__ == 'MD'
#or
p.add_link(Statement(x)).__location__ == 'MD'
# with .link
p.link(x).__location__ == 'MD'
- Fixed a bug where if False or True were bound, they would be matched by falsy/truthy values that were bound afterward.
- Fixed a bug where assignment operators were not allowing nested dicts in lists.
- Fixed a bug with the tester.py script that bound
ctrl + c to clear the screen. Changed it to ctrl + [ because the other one is used for copy on sone operating systems.
- Fixed an issue where
Param objects were not being recognized by Statment objects
- Fixed
Pypher.clone() was not creating new .next instances correctly in the linked list
- Fixed
Pypher.clone(), it was adding an empty .PROPERTY to the resulting Cypher
Pypher.clone() method will create a carbon copy of the Pypher instance and its bound params.Params.clone() method will create a new instance of a Params instance with the same prefix, key, and defined bound_params.
Conditional, ConditionalAND, and ConditionalOR objects that will produce lists with parenthesis with a separator.
- Fixed a bug with
Pypher.append() that will allow you to combine multiple Pypher instances into one.
- Fixed an issue with
Params.reset() method not working properly.
- Added
Anon.__call__ that will create an empty Pypher instance.
- Fixed issue #17 where falsy values were not being honored in
Operator objects
- Prompt Toolkit 2.0 has been released so now when
python setup.py install is executed, tester.py will work out of the box
Relationship now accept min_hops and max_hops arguments that will resolve to a pattern.
- Ensured that
MapProjection could have a name kwarg
- Modified
List to use a comma as the concatenator instead of a blank space
- Ensured ordering of params for dict assignments
ctrl-c shortcut to clear the Pypher pane in the tester.py consolefunc_raw=False argument to the Pypher.builder.crete_function method that will create a FuncRaw class instead of a Func when set to true.
- Added a few missing statements;
XOR, NULL, IS_NULL, IS_NOT_NULL, NOT, and OR
- A bug where dynamic statements were printing out
STATEMENT. Now p.some_statemnt(1, 2, 3) will return some_statement 1, 2, 3
- Ensured ordering of
kwargs in Map and MapProjection objects
- Map and map projection support via
Map and MapProjection respectively.
- Dict support for assignments
- Very alpha CLI app used to test Pypher scripts. Simply run
python tester.py after installing this package.
Entity objects now accept a Label instance for the labels or types argument.Relationship objects now accept a types kwarg that will supercede the labels definition.
Property objects' alias prop now work as expected.- Fixed a few bugs regarding
Param.name and Pypher.bound_params keys.
- Added optional params argument to the
Pypher class that will allow self-defined Params objects to be used instead of being created when a Pypher instance is created.
- Ensured that params that share the same value with previously bound params return the same reference.
- Ensured that params passed as a value only, but is the name of an existing key tha thas be bound, returns the same reference.
- Changed the
ID class to subclass FuncRaw so that its arguments are not automatically bound.
- Fixed the name of the param staring with a
$
Pypher.OperatorRaw a class where the operator's argument is not automatically bound in the resulting Cypher.
- Fixed an issue where
Pypher.reset() was not clearing out the old bound params
- Made
Pypher.Alias and Pypher.Rexp sub-class Pypher.OperatorRaw
- Fixed a bug where
Pypher.Link class _ALIAS list were not being stored and referenced by the system properly
- Fixed division of Pypher objects for Python 3+
- The default param name now starts with a dollar sign. And if the manually named param does not start with one, it will be prepended to the name
pypher.builder.Raw and pypher.builder.FuncRaw objects will now adopt bound_params from Pypher and Partial objects
- The
pypher.builder.Label class did not add back ticks to the labels.
- All labels and properties are now wrapped in back ticks to support labels or properties with spaces and other weird characters. From: "n.name" to "n.
name"
- A bug where the referenced/right-side operators were not behaving correctly if the right side was not a Pypher object.
99 - p.__field__ would output p.field - 99 it now outputs 99 - p.field
- Support for Partial objects.
pypher.builder.RElATIONSHIPS['both'] -- this relationship doesn't exist as it was defined.
