From 0ddf7d9c35eb2dd5f368e7a5735970ef1fd41fc6 Mon Sep 17 00:00:00 2001 From: Emilio Jesus Gallego Arias Date: Sun, 19 Nov 2017 19:08:35 +0100 Subject: [printing] Deprecate all printing functions accessing the global proof. We'd like to handle proofs functionally we thus recommend not to use printing functions without an explicit context. We also adapt most of the code, making more explicit where the printing environment is coming from. An open task is to refactor some code so we gradually make the `Pfedit.get_current_context ()` disappear. --- plugins/ssr/ssrcommon.ml | 12 ++++++------ plugins/ssr/ssrelim.ml | 8 ++++---- plugins/ssr/ssrequality.ml | 28 ++++++++++++++-------------- plugins/ssr/ssrfwd.ml | 23 ++++++++++++----------- plugins/ssr/ssripats.ml | 2 +- plugins/ssr/ssrparser.ml4 | 2 +- plugins/ssr/ssrprinters.ml | 2 +- plugins/ssr/ssrvernac.ml4 | 12 +++++++----- 8 files changed, 46 insertions(+), 43 deletions(-) (limited to 'plugins/ssr') diff --git a/plugins/ssr/ssrcommon.ml b/plugins/ssr/ssrcommon.ml index c1d7e6278..83b454769 100644 --- a/plugins/ssr/ssrcommon.ml +++ b/plugins/ssr/ssrcommon.ml @@ -240,7 +240,7 @@ let interp_refine ist gl rc = in let sigma, c = Pretyping.understand_ltac flags (pf_env gl) (project gl) vars kind rc in (* ppdebug(lazy(str"sigma@interp_refine=" ++ pr_evar_map None sigma));
