[julia-users] How do I turn a string into a variable
I want to be able to write: @makevar(life, 42) which will expand to life = 42 How do I do this? Why do I want to do it? Because it would be cool to have a feature like in Octave where I could load an HDF5 file, and it automatically sets the variables from the file.
Re: [julia-users] How do I turn a string into a variable
It's easy to write a macro that takes a static literal string and makes a variable out of it. It's much harder (maybe impossible) to write a macro that takes in a variable that happens to be bound to a string value and to make a variable out of the value you happen to have stored in that variable. Another way to put it: macros don't exist inside of the world of values -- they only live in the world of syntax. Could you get a similar (and cleaner) effect by populating a Dict instead? -- John On Dec 17, 2014, at 5:37 AM, Zeta Convex zeta.con...@gmail.com wrote: I want to be able to write: @makevar(life, 42) which will expand to life = 42 How do I do this?

For the usage goal, have you seen HDF5.jl? https://github.com/timholy/HDF5.jl#quickstart The @save and @load macros will do this for you (there are some limitations - but Tim, Simon, et al. have pushed things about as far as they possibly can at present).
