Little change of DT_Var.py for dtml-var modification
Hallo all, I want to add parameter "cut=###" to <dtml-var> tag. It is opposite for "size" parameter, at Zope 2.5.1 you can find it around line 260 of DT_Var.py. But after restart (*.pyc file successfully created) the modified tag <dtml-var file cut=200> does not cut anything, returns whole text from file instead file with missing first 200 chars... Does somebody have idea, where I need to change more? Many thanks, J. Lukesh DT_Var.py: if have_arg('size'): size=args['size'] try: size=int(size) except: raise 'Document Error',( '''a <code>size</code> attribute was used in a <code>var</code> tag with a non-integer value.''') if len(val) > size: val=val[:size] l=val.rfind(' ') if l > size/2: val=val[:l+1] if have_arg('etc'): l=args['etc'] else: l='...' val=val+l return val # added 'cut', opposite derivate from 'size' if have_arg('cut'): cut=args['cut'] try: cut=int(cut) except: raise 'Document Error',( '''a <code>cut</code> attribute was used in a <code>var</code> tag with a non-integer value.''') if len(val) > cut: val=val[cut:] l=val.rfind(' ') if l > cut/2: val=val[:l+1] if have_arg('etc'): l=args['etc'] else: l='...' val=l+val return val And I have defined here (around line 160) def __init__(self, args, fmt='s'): if args[:4]=='var ': args=args[4:] args = parse_params(args, name='', lower=1, upper=1, expr='', capitalize=1, spacify=1, null='', fmt='s', size=0, cut=0, etc='...', thousands_commas=1, html_quote=1, url_quote=1, sql_quote=1, url_quote_plus=1, missing='', newline_to_br=1, url=1)

return val
# added 'cut', opposite derivate from 'size' if have_arg('cut'): cut=args['cut']
Your "cut" handling comes a bit late: Code after a "return" is ineffective.... -- Dieter
