[antlr-interest] Code beautifier-indentation

[Meena Moktali]

hi John,
The final goal is to indent the code according to standards for each block.
I can give u an example as below..
Can u help me with this?

Meena

ORIGINAL CODE  (no indentation followed)
-------------

if L_RTRN_CD = SUCCESS in STD_RTRN_CD
*> Corebank account or currency are required <*
if (ACT_RECVD_CLRG_ID of ACCTG_TRANS_PD_WD of ACCTG_TRANS_PD_W
= ' '
or ARID_ITEM of ACCTG_TRANS_PD_WD of ACCTG_TRANS_PD_W
= ' ')
and
PSTG_ORGNL_ISO4217 of ACCTG_TRANS_PD_WD of ACCTG_TRANS_PD_W
= ' '
map EITHER_ACCOUNT_OR_CURRENCY in KSPS8_MSG
to TEXT_CODE of STD_MSG_PARM_V of STD_MSG_CLIENT_SRV_I
map 'ACCTG_TRANS_PD_WD'
to VIEW_LONG_NAME of STD_MSG_CLIENT_SRV_I
map BUSINESS_ERROR in STD_RTRN_CD
to L_RTRN_CD
map 'ACT_RECVD_CLRG_ID'
to FIELD_LONG_NAME of STD_MSG_CLIENT_SRV_I
map 'ADZRLP'
to MESSAGE_SET_NAME of STD_MSG_PARM_V of STD_MSG_CLIENT_SRV_I
  endif
endif

How complex is the "beautification"?  I.e., are you literally only changing
indentation or do you need to completely reformat the code?  If it's the
first, you can take some really simple approaches but if it's the latter
than you're into the world of full-on source-to-source transformation.

Take care,
