Mathenize

Small package to make it possible to perform math operations from strings in the Julia language, written by Luis C. Gómez.

Most math operations are possible, check Mathematics - The Julia Language to check functions.

Installation and Usage

Use Julia 1.6.1 or above.

(@v1.6) pkg> add Mathenize

Displaying log info.

using Mathenize
x = calculate("sqrt(complex(-90)) + 10im", true)

Output:

┌ Info: -> sqrt(complex(-90)) + 10im <-
│  └Tasks: 3
│  └Any[:+, :(sqrt(complex(-90))), :(10im)]
│    └ Performing subtasks:
│     └ sqrt is a valid symbol | Belongs to: sqrt(complex(-90)) | Length: 1 - 2
│     └ complex is a valid Expression found in sym
│     └ complex(-90) is permitted | Belongs to: sqrt(complex(-90)) | Length: 2 - 2

│     └ 10 is a valid number | Belongs to: 10im | Length: 2 - 3

Difference between parsing with Core.eval(Base.Math, :Expr) and Mathenize

Using Mathenize, the following input will result in:

x = calculate("for i in 1:10; print(i); end;")
ERROR: Error in Mathenize syntax. Check the log using calculate(math::String, true)
└ ->for i = 1:10
    #= none:1 =#
    print(i)
end is not recognized as a valid math operation.
 └ The input given is a Expr that contains Any[:(i = 1:10), quote
    #= none:1 =#
    print(i)
end]

Using Core.eval(Base.Math, :Expr)

Core.eval(Base.Math, Meta.parse("for i in 1:10; print(i); end;"))
