SET{"name" value="..."} -- set a variable

  • Set a named variable that can be retrieved later with %GET{}%. No output is shown, e.g. %SET{}% resolves to an empty string. It is also possible to set a JSON object using a JSON path. The %SET{}% and %GET{}% variables are handled by the SetGetPlugin.
  • Syntax: %SET{ "name" value="..." remember="1" }%
  • Parameters:
    Parameter DescriptionSorted ascending Default
    remember="1" If set, the variable will be stored persistently so that it can be used later in any TWiki topic. Alternatively use the store parameter. See important notes. "0"
    "name" Name of variable. Alphanumeric characters, dashes and underscores can be used. (required)
    store="..." Specify a store name to persistently store the variable, such as store="Parts". Use alphanumeric characters, dashes and underscores for the name. For better performance, store is preferred over the remember parameter if you need to store a large dataset. See important notes. ""
    value="..." Value of variable. Escape double quotes with backslash. (required, may be empty)
  • Example: %SET{"lunch" value="Sushi"}% - see more examples.
  • JSON Syntax: %SET{ name = { ... } remember="1" }% - see description.
    • An optional remember="1" or store="..." parameter can be appended. If specified, the JSON object will be stored persistently so that it can be used later in any TWiki topic.
  • Example to set, modify and get a JSON object:
    • %SET{ menu = { "File": { "New": [ "new", "F" ], "Open": [ "open", "F" ] }, "Edit": { "Copy": [ "cpy", "F" ], "Paste": [ "pst", "F" ] } } }% - set a JSON object
    • %GET{ menu }% - returns: {"File":{"New":["new","F"],"Open":["open","F"]},"Edit":{"Copy":["cpy","F"],"Paste":["pst","F"]}}
    • %SET{ menu.File.Open[1] = "T" }% - modify a JSON object
    • %GET{ menu }% - returns: {"File":{"New":["new","F"],"Open":["open","T"]},"Edit":{"Copy":["cpy","F"],"Paste":["pst","F"]}}
    • %SET{ menu.Edit.Cut = [ "cut", "T" ] }% - add to a JSON object
    • %GET{ menu }% - returns: {"File":{"New":["new","F"],"Open":["open","T"]},"Edit":{"Copy":["cpy","F"],"Paste":["pst","F"],"Cut":["cut","T"]}}
