Re: How can we dynamically create variable names from changing value "x" on a loop?

Very interesting discussion! I'm still curious though. Since the op already takes the json based file and turns it into an array ( probably using an existing json library.) Since this step is already done, and the array esists, is there an actual benefit to then breaking that array into

Hi Mark, There's a reason why I haven't posted the code of explodeRow... but I'm sure it _could_ be efficient! Thanks for reminding me about split with one delimiter - I never use that. I think when I first encountered it I was so annoyed by the thought that it was pointless, because what I

Re: How can we dynamically create variable names from changing value "x" on a loop?

It's easy to dynamically create and set the values of variables, using the "do" command, e.g.: do format("put tValue into %s", tVarName) I do lots of work with TSV files, which have a first row of field names, and for years have used a function like this to create local variables,

Re: How can we dynamically create variable names from changing value "x" on a loop?

Why not just leave it as an array? In fact, if you want to have separate preferences categories, that's easy enough to do too. local sPrefsA put getPref ("preferences/modules/color-meditation") into sPrefsA[ColorMedPrefs] at this point you have an local script array variable structured like

Given this scenario: We fetch a preference array from some json on disk We want to insert the key-values into separate discrete local vars in the stack script function getUserPreferences # the following function fetches an object in a JSON file: put getPref
