eval works in global scope but returns its result locally, so something like this works easily enough: rulestrs = ["x[1] && x[2]", "x[3] || x[4]", "x[1] && (x[2] || x[3])"] function evaluate(rules, boolList) rulefuncs = [eval(parse(string("x -> ", rule))) for rule in rules]

Reading the rules from a file, how can I convert the strings to such anonymous functions? On Tuesday, April 26, 2016 at 6:48:21 PM UTC+2, Josh Langsfeld wrote: > > Maybe a better design would be to store the rules as anonymous functions > rather than code strings? Something like: > > ``` >

I am writing code for regulated Flux Balance Analysis. I need to read some regulatory rules from a file and predict the future state of the genes in the network. In this example x is a vector of genes being on or off, and each rule belongs to a reaction, i.e. if the rule is true, then the

[julia-users] Re: Evaluation of boolean expression fails

Maybe a better design would be to store the rules as anonymous functions rather than code strings? Something like: ``` rules = [(x -> x[1] && x[2]), (x -> x[3] || x[4])] #parentheses not required result = [rule(boolList) for rule in rules] ``` On Tuesday, April 26, 2016 at 12:09:33 PM UTC-4,
