In December 2020, Calico Pie implemented a new plugin store which can host Help pages if the plugin author wishes.

In ƒh7 accessing this Help can be invoked via a function in the fhUtils library, via fh.helpButton(page,label) which creates an Iup button with label label that opens page title page in the plugin store help system.

If you wish to implement Help in a plugin for V5 or V6, you can include the following code (which will also work in V7).

local function helpButton(page,label)
    local helpRoot = 'http://pluginstore.family-historian.co.uk/help/'    
    local page = page or ''
    local label = label or 'Help'
    local cmd = helpRoot..page 
    local btn = iup.button{padding="4x4",expand="HORIZONTAL",title=label,
        action=function(page)
            fhShellExecute(cmd)
            end
        }
     return btn       
end
