刀具列表中，如何捕获最短刀长函数？

fengyunhun

下面是我改的后处理，我希望刀具列表信息把最短刀长带入。请问如何才能捕获最短刀长？
global lengst mom_tool_minimum_length
   set prev_tool_type ""
   set lengst [format %.2f $mom_tool_minimum_length]
   foreach tool $tool_list {

      set tool_type $tool_data_buffer($tool,type)

     # Output tool type header if it changes.
#      if { ![string match "$tool_type" $prev_tool_type] } {
#         if { [info exists tool_data_buffer($tool_type,header)] && \
#              [string length $tool_data_buffer($tool_type,header)] != 0 } {
#            shop_doc_output_literal "$tool_data_buffer($tool_type,header)"
#         }
#      }

#      if [info exists tool_data_buffer($tool,output)] {
         shop_doc_output_literal "($tool MinL=$lengst)"
#      }
#     set prev_tool_type $tool_type
   }


后处理出来实际情况如下：
