Leonardo de Moura 54f7bf9391 fix(frontends/lean, library/tactic): remove redundant error messages, and fix position of error messages ... Summary: We minimize the number of "'sorry' used warning messages". We also re-target the error to the main declaration. Example: foo._main ==> foo We do not report for auxiliary declarations such as "_example" and "foo.equations._eqn_1" Get rid of the redundant error message "error : failed" for tactics. We added "silent failures" in the tactic framework. We do not store line/col information for tactics nested in notation declarations. Before this commit, we would have tactics such as (tactic.save_info line col) nested inside of notation declarations.		2017-02-07 20:25:28 -08:00
