From b21f71c1bb79d3979505ad6ad1e496472b38c6b9 Mon Sep 17 00:00:00 2001 From: Hans Bolinder Date: Thu, 17 Dec 2015 12:41:44 +0100 Subject: stdlib: Update erl_parse(3) Calls to map_anno(), fold_anno(), and mapfold_anno() with lists of erl_parse trees have been replaced. Those functions accept lists of erl_parse trees, but it was not the intention when the functions were introduced, and it is not documented. --- lib/stdlib/doc/src/erl_parse.xml | 120 ++++++++++++++++++++++++--------------- 1 file changed, 73 insertions(+), 47 deletions(-) (limited to 'lib/stdlib/doc/src/erl_parse.xml') diff --git a/lib/stdlib/doc/src/erl_parse.xml b/lib/stdlib/doc/src/erl_parse.xml index 0938b5dec3..13be488c33 100644 --- a/lib/stdlib/doc/src/erl_parse.xml +++ b/lib/stdlib/doc/src/erl_parse.xml @@ -4,7 +4,7 @@
