Hi, I see that m4sugar has been included in autoconf and bison. It sounds like it could be made into a stand alone package. Unfortunately, it is not.
https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Programming-in-M4sugar.html#Programming-in-M4sugar They are installed in something like the following via homebrew. However, the location is not standard. I could manually set M4PATH or use -I manually. But it could break when there is an update in homebrew and I will always need to monitor the m4sugar path which is inconvenient. /usr/local/Cellar/bison/3.0.5/share/bison/m4sugar/ /usr/local/Cellar/autoconf/2.69/share/autoconf/m4sugar/ /usr/local/Cellar/bison/3.0.4_1/share/bison/m4sugar/ Could anybody show me the best way to let m4 use m4sugar? Thanks. -- Regards, Peng
