Joachim, This what I got on mine. I tried your fix using prolog.el and eclipse.el and it seemed to work on the simple test that I sent. Here is the output that you requested. [eclipse 2]: util:streams. WARNING: module 'util' does not exist, loading library... util.eco loaded in 0.00 seconds $&(stream(0)) pipe read user ( stdin input user_input ) $&(stream(1)) pipe write user ( stdout output warning_output log_output user_output toplevel_output debug_output answer_output ) $&(stream(2)) pipe write error ( stderr error user_error ) $&(stream(3)) null update null ( null ) $&(stream(4)) queue read "" ( ec_rpc_in ) $&(stream(5)) queue update "" ( ec_rpc_out ) $&(stream(6)) pipe read fd ( toplevel_input ) $&(stream(8)) pipe read fd ( debug_input ) Thanks for your help.Alexis El amor a la patria tiene que transformarse en acción y ésta tiene que ser acción para el bien común.

If you manually set :- set_stream_property(error, flush, end_of_line). then it should work as expected (you can also put this command in a .eclipserc file in your working directory or home directory). To enable me to implement a better fix, could you send me the output that util:streams. produces when you call it from your emacs-embedded eclipse? Thanks, Joachim On 14/07/17 10:45, Alexis H.
