Examples ======== Example to construct a simple first degree equation solver: >>> from sympy.utilities.matchpy_connector import WildDot, Replacer >>> from sympy import Equality, Symbol >>> x = Symbol("x") >>> a_ = WildDot("a_", optional=1) >>> b_ = WildDot("b_", optional=0) The lines above have defined two wildcards, ``a_`` and ``b_``, the coefficients of the equation `a x + b = 0`. The optional values specified indicate which expression to return in case no match is found, they are necessary in equations like `a x = 0` and `x + b = 0`. Create two constraints to make sure that ``a_`` and ``b_`` will not match any expression containing ``x``: >>> from matchpy import CustomConstraint >>> free_x_a = CustomConstraint(lambda a_: not a_.has(x)) >>> free_x_b = CustomConstraint(lambda b_: not b_.has(x)) Now create the rule replacer with the constraints: >>> replacer = Replacer(common_constraints=[free_x_a, free_x_b]) Add the matching rule: >>> replacer.add(Equality(a_*x + b_, 0), -b_/a_) Let's try it: >>> replacer.replace(Equality(3*x + 4, 0)) -4/3 Notice that it will not match equations expressed with other patterns: >>> eq = Equality(3*x, 4) >>> replacer.replace(eq) Eq(3*x, 4) In order to extend the matching patterns, define another one (we also need to clear the cache, because the previous result has already been memorized and the pattern matcher will not iterate again if given the same expression) >>> replacer.add(Equality(a_*x, b_), b_/a_) >>> replacer._matcher.clear() >>> replacer.replace(eq) 4/3 Fcommon_constraintslambdifyrczt|_||_||_||_i|_dSrK)r7ManyToOneMatcher_matcher_common_constraint _lambdify_info _wildcards)r\rrrs rGr^zReplacer.__init__s60022 "4! /1rI lambda_strr{.cXtdt|tS)Nzfrom sympy import *)execevallocals)r\rs rG _get_lambdazReplacer._get_lambda s% "###J)))rIconstraint_exprcondition_templatec $d|tD}d|}t|}||}t |d|d|dS)Ncg|] }|j Srbr.0xs rG z3Replacer._get_custom_constraint..sFFFAFFFrI, lambda z: ())atomsrejoinrformatr7CustomConstraintr)r\rrwilds lambdaargsfullexpr conditions rG_get_custom_constraintzReplacer._get_custom_constraintsFF!6!6}!E!EFFFYYu%% o..&--h77 ''   BzBBiBBB C CEE ErIc.||dS)Nz ({}) != Falserr\rs rG_get_custom_constraint_nonfalsez(Replacer._get_custom_constraint_nonfalses**?OLLLrIc.||dS)Nz ({}) == Truerrs rG_get_custom_constraint_truez$Replacer._get_custom_constraint_trues**?NKKKrINrconditions_trueconditions_nonfalsect|}t|}jdd}fd|D}fd|D}||||tj|g|R} jrbddd|tDdt|} | } | }n<j d|tDjrt||}j| |dS)Nc:g|]}|Srb)rrcondr\s rGrz Replacer.add..#s:&P&P&P7;D , ,T 2 2&P&P&PrIc:g|]}|Srb)rrs rGrz Replacer.add..%s:*X*X*X;?D 0 0 6 6*X*X*XrIrrc3$K|] }|jV dSrKrrs rG zReplacer.add..+s$-X-Xaf-X-X-X-X-X-XrIz: c.i|]}t||Srbr)ris rG z Replacer.add../s #L#L#L!CFFA#L#L#LrI)rrextendr7PatternrrrrerrrupdaterVrrradd) r\rrrrr constraintsconstraint_conditions_trueconstraint_conditions_nonfalsepatternr lambda_exprs ` rGrz Replacer.adds~~{++ -aaa0 &P&P&P&P?N&P&P&P"*X*X*X*XCV*X*X*X&56669:::/$5555 > Nv499-X-Xdjj>W>W-X-X-X#Y#Yvv]ghs]t]tvvJ**:66K%KK O " "#L#Ltzz(7K7K#L#L#L M M M : =)+t<.Is)6g6g6gQUQRTUtq7I16g6g6grIrArb)r7preorder_iter_with_positionnextrCrmatchrrappendrrxreplaceitems functionsreplace StopIteration) r\ expressionrinfosreplaced replace_countsubexprposreplacement_datasubstrresults ` rGrzReplacer.replace4s  IMM]Y-F-FH ' C CJ O O   .24 8K8KG8T8T3U3U.V.V+$ez7&6&B  %5%:;;;;&6 ~i!,!5!5u!5!5!,!5!56g6g6g6gY^YdYdYfYf6g6g6g!h!h!(!2!:!::sF!S!SJ#HE$D Q M+ IMM]Y-F-F, : u$ $ sCD DD)r)r_r`ra__doc__listrr^rgrr-rrrrrrrrrrbrIrGrrs66p35u[`22422TX2222*c*hsDy.A****EdEPSEX`adfjajXkEEEEMtMQTVZQZH[MMMML4LHSRVYDWLLLLJL.0d000DJ0!%d08;0GK0000,  S      rIr)T)]rrtypingrrrrrsympy.core.sympifyrsympy.externalr sympy.functionsr r r r rrrrrr%sympy.functions.elementary.hyperbolicrrrrrrrrrrrr(sympy.functions.elementary.trigonometricr r!r"r#r$r%'sympy.functions.special.error_functionsr&r'r(r)r*sympy.core.addr+sympy.core.basicr,sympy.core.exprr-sympy.core.mulr.sympy.core.powerr/sympy.core.relationalr0r1sympy.core.symbolr2&sympy.functions.elementary.exponentialr3sympy.integrals.integralsr4sympy.printing.reprr5sympy.utilities.decoratorr6r7__doctest_requires__r9r:r;r<matchpy.expressions.functionsr=r>r?registerrHrUrVrerrrrrrrbrIrGr s  88888888888888''''''((((((WWWWWWWWWWWWWWWWWWWWWWWW~~~~~~~~~~~~~~~~~~~~~~~~~~~~WWWWWWWWWWWWWWWWVVVVVVVVVVVVVV""""""  88888888$$$$$$666666......%%%%%%888888 - " " , L2ccccccccccccZZZZZZZZZZIx   Is!!#&&&Is!!#&&&!!#&&&!!#&&&Is!!#&&&!!#&&&!!#&&&Ix   !!(+++Iz"""!!*---IsIsIuIz"""Ix   Ix   IsIrItItIsIsIsIsIsIsItItItItItItItItItItItItIuIuIuIuIuIuWh@@ @We%%%V_X+++V_U$$$* )%00222102 %       %%%%%%%%L)))-----Hf--*)-`L)))m*) L)))}*) L)))}*)    j L)))HHHHHHH*)HHHrI
