Think you for reply! It is my first post at google group, as I am not good at english.
I am a embedded programer, use C language as major language. I maintain about 30+ projects, most of them is similar, just has little different. Some time that diffrents is hard to use C marco to handle it . So I as that question, if I can use Leo node as function and generate that differents part, it is perfect. It seem like Leo act as writing DSL, and other format document is the output. That is what I real to want. Thinks again, for your reply! 在 2016年8月18日星期四 UTC+8下午9:03:01，Edward K.
