GWT number constants generator ?!!

[Ahmad Bawaneh]

Dears

I am trying to figure out a way to generate and update GWT number constants, looking around i could not find the tool that generates those number constants properties files, they are being generated using an external tool that is not present in the GWT repo.

Now since i could not find the tool i decided to work on GWT CLDR importer tool to add a NumberConstants generator, i was able to read cldr data and generated classes for some of the attributes from the original properties file, but then i faced a problem where some of those attribute was pretty clear where to find in the CLDR data but for some other i was unable to find anything to lead me on how they were originally generated

properties i was able to find in the cldr data and generate the proper code for 

------------------------------------------------------------------------------------------------------

decimalSeparator

groupingSeparator

percent

plusSign

minusSign

exponentialSymbol

perMill

infinity

notANumber

currencyPattern

decimalPattern

scientificPattern

percentPattern

Properties that i cant figure out where to find or how to generate at all

--------------------------------------------------------------------------------------------

simpleCurrencyPattern

monetarySeparator

monetaryGroupingSeparator

globalCurrencyPattern

defCurrencyCode

zeroDigit

for some reason i feel like this is related to the same issue with TimeZone constants as mentioned in this thread https://groups.google.com/forum/#!topic/google-web-toolkit-contributors/VN4ATVrLrTA

I will appreciate any help as this is one of the things that is delaying the release of GWT 3.0

the tool that i use to generate CLDR related classes is here https://github.com/vegegoku/gwt-cldr-importer which is bases on the GWT tools.

thanks

I'm not familiar with this but looking at the internal tool, it looks like;

zeroDigit data is coming from "commmon/upplemental/numberingSystems.xml". 

defCurrencyCode is coming from "common/supplemental/supplementalData.xml".

monetarySeparator is under "numbers/symbols/decimal" locale data.

monetaryGroupingSeparator is under "numbers/symbols/group" locale data.

currency patterns are coming from the currencyFormats section of locale data.

Logic for simpleCurrencyPattern:

def CreateSimpleCurrencyPattern(ref_pattern):
  """Return simple currency pattern.

  Before this pattern is available in CLDR, created based on general currency
  pattern by applying this transformation:
  \\00a4+ ==> \\u00a4\\u00a4\\u00a4\\u00a4

  Args:
    ref_pattern: pattern to unescape to create the simple pattern
  Returns:
    simple currency pattern.
  """
  return re.sub(ur'\u00a4+', ur'\u00a4\u00a4\u00a4\u00a4', ref_pattern, 0)

Logic for globalCurrencyPattern:

def CreateGlobalCurrencyPattern(ref_pattern):
  """Return global currency pattern.

  Before this pattern is available in CLDR, created based on simple currency
  pattern.

  Args:
    ref_pattern: pattern to escape to create the global pattern
  Returns:
    the global currency pattern
  """
  simple_pattern = CreateSimpleCurrencyPattern(ref_pattern)
  global_pattern = ''
  in_quote = False
  for ch in simple_pattern:
    if ch == '\'':
      in_quote = not in_quote
    elif ch == ';' and not in_quote:
      global_pattern += ur' \u00a4\u00a4'
    global_pattern += ch
  global_pattern += ur' \u00a4\u00a4'
  return global_pattern
