I have kept this a secret for a long time, but after using this in many projects, it is now time to publish my user preferences library for LiveCode/Revolution.

Below follow the scripts without comments. I will write more about it in a future blog post.

function saveGlobalsToVar theGlobals
  do “global” && theGLobals
  put theGlobals & return into tempVar
  repeat for each item x in theGlobals
    do “put urlEncode(” & x & “) & return after tempVar”
  end repeat
  return tempVar
end saveGlobalsToVar

on readVarToGlobals theVar
     — breakpoint
     put line 1 of theVar into myGlobals
     delete line 1 of theVar
     do “global” && myGlobals
     repeat with x = 1 to number of items of myGlobals
          put “put urlDecode(line x of theVar) into” && item x of myGlobals into myScript
          do myScript
     end repeat
end readVarToGlobals

on writePrefs theGlobals,thePrefsFilename
  put saveGlobalsToVar(theGlobals) into myPrefs
  put prefsFile(thePrefsFilename) into myPrefsFile
  set the filetype to “sysppref”
  open file myPrefsFile for binary write
  write compress(myPrefs) to file myPrefsFile
  close file myPrefsFile
end writePrefs

on readPrefs thePrefsFilename
  put prefsFile(thePrefsFilename) into thePrefsFilename
  if there is a file thePrefsFilename then
    open file thePrefsFilename for binary read
    read from file thePrefsFilename until EOF
    close file thePrefsFilename
    put decompress(it) into myPrefs
    — put myPrefs
    readVarToGlobals myPrefs
  else
    return “Error: File does not exist.”
  end if
end readPrefs

function prefsFile theFilename
     if gU3App is true then
          put $u3_app_data_path & slash & theFilename into myFilePath
          replace backslash with slash in myFilePath
     else if the platform is “MacOS” then
          put specialFolderpath(“preferences”) & “/” & theFilename into myFilePath
     else if the platform is “win32” then
          put specialFolderpath(26) & “/” & theFilename & “.ini” into myFilePath
     else if the platform is “Linux” then
          put $HOME & slash & dot & theFilename into myFilePath
     else
          put stackToFilename(theFilename) into myFilePath
     end if
     return myFilePath
end prefsFile

Here’s a script, which I just posted to the Revolution forum. I post it on my blog, because I like the script and it might be useful to many people. It should also be simple to translate this to PHP for instance.

This script generates passwords with length theLength, choosing consonents and vowels semi-randomly such as to keep the password speakable. This function allows for double consonants while still keeping the password speakable.

function speakablePassword theLength
     put “bcdfghjklmnprstwyz” into myConsonants
     put “aeiou” into myVowels
     put “” into myPass
     repeat myPasswordLength
          if char -1 of myPass is in myConsonants then
               if char -2 of myPass is in myConsonants or
                  length(myPass = 9) then
                    put any char of myVowels after myPass
               else
                    if any item of “true,false” then
                         put any char of myVowels after myPass
                    else
                         put any char of myConsonants after myPass
                    end if
               end if
          else
               put any char of myConsonants after myPass
          end if
     end repeat
     return myPass
end speakablePassword

The csv to tab delimited conversion script, which I just posted on the Revolution Use List. I post it here just in case it is useful to someone. This script doesn’t take returns and tabs inside cells in consideration.

function csv2tab theData
    repeat for each line myLine in theData
         repeat for each word myWord in myLine
              if char 1 of myWord is quote and (char -2 of myWord is
               quote or char -1 of myWord is quote) then
                   replace comma with “<#>” in myWord
              end if
              put myWord after myNewData
         end repeat
         put cr after myNewData
    end repeat
    replace comma with tab in myNewData
    replace “<#>” with comma in myNewData
    return myNewData
end csv2tab

What to do when building standalones goes mysteriously wrong?

– try removing passwords from stacks

– try toggling the destroyStack property

– check whether pictures are referenced or imported as controls

– make sure that pictures are in the correct location relative to your stack

– make sure to use relative file paths for portability

– select “Select inclusions” instead of “Search for required inclusions” on the General pane of the standalone application settings

– after selecting “Select inclusions”, make sure that you actually include all components that you need for your stack, this may involve knowing for sure what each component does

– you might try to forget about profiles, just select “Remove all”

– if you build for multipe platforms, try building for one platform at a time

– quit and restart Revolution without saving your project right after building a standalone

– quit and restart Revolution after saving your project and before building a standalone

– when moving your standalone for Mac OS 9 or Mac OS X to a different computer, make sure to create a sit or zip file of your standalone first

– when uploading your compressed standalone or exe file to a server, make sure that your FTP software treats it as binary

– you might try to build a standalone while suppressing messages (see Development menu)

– you might try to build a standalone while suppressing errors (see Development menu)

– if building standalones takes ages, set the cREVKeepDevelopmentProperties of your mainstack to true

– Error: “A stack “answer dialog” in file (path to my stack) is already in memory. The Revolution UI does not distiguish stacks with have identical names, so editing these stack files which both are in memory could result in data loss.” When the preference “If destroyStack is false, when closing last stack in file:” is set to “Don’t close the file” then a built standalone is partially corrupted or the building process throws errors and aborts. This was not the case with version 3.5. RunRev reports: “I think this issue is related to a certain preference setting. It appears to be fixed in the development builds of the next version of Revolution which are available to our enterprise customers. However if you are using 4.0, I think the problem can be worked around by changing the preference “If destroyStack is false, when closing last stack in file:” to something other than “Ask”. This can be found by doing Edit -> Preferences -> Files & Memory.” I have no confirmation, yet.
