class
pytexit.core.core.
LatexVisitor
(dummy_var, upperscript, lowerscript, verbose, simplify_multipliers, simplify_fractions, simplify_ints, tex_multiplier)¶ Bases:
ast.NodeVisitor
Parameters: - simplify_multipliers (bool) –
if
True
, simplify expression if multiplier is a float. Ex:2*a -> 2a a*3.5 -> 3.5a
see
visit_BinOp()
for more information. DefaultTrue
. - simplify_fractions (bool) – if
True
, simplify fractions. seevisit_BinOp()
for more information. DefaultFalse
. - simplify_ints (bool) – see
visit_BinOp()
for more information. DefaultFalse
.
-
brackets
(expr)¶ Enclose expr in {…}
-
convert_symbols
(expr)¶
-
division
(up, down)¶
-
generic_prec
(n)¶
-
generic_visit
(n)¶ Called if no explicit visitor function exists for a node.
-
group
(expr)¶ Returns expr, add brackets if needed
-
looks_like_int
(a)¶ Check if the input
a
looks like an integer
-
operator
(func, args=None)¶
-
parenthesis
(expr)¶
-
power
(expr, power)¶
-
prec
(n)¶
-
prec_BinOp
(n)¶
-
prec_UnaryOp
(n)¶
-
sqrt
(args)¶
-
visit_Add
(n)¶
-
visit_Assign
(n)¶ Rewrite Assign function (instead of executing it)
-
visit_BinOp
(n)¶
-
visit_BitAnd
(n)¶
-
visit_BitOr
(n)¶
-
visit_BitXor
(n)¶
-
visit_Call

(n)¶
-
visit_LShift
(n)¶
-
visit_ListComp
(n, kwout=False)¶ Analyse a list comprehension Output : - kw : used by some functions to display nice formulas (e.g : sum) - args : standard output to display a range in other cases
-
visit_Mod
(n)¶
-
visit_Mult
(n)¶
-
visit_Name
(n)¶ Special features: - Recognize underscripts in identifiers names (default: underscore) - Recognize upperscripts in identifiers names (default: ˆ, valid in Python3) Note that using ˆ is not recommended in variable names because it may be confused with the operator ^, but in some special cases of extensively long formulas with lots of indices, it may help the readability of the code
