From 3b4137c64d9259c9f5ac59b89ff44f340256ee7a Mon Sep 17 00:00:00 2001 From: Hans Bolinder Date: Thu, 16 Jun 2011 09:00:34 +0200 Subject: Remove Dialyzer warnings The code that deals with the POSIX version of regexps has been commented out. Robert will add an option as well as some way to set the option in the source file later. --- lib/parsetools/src/leex.erl | 97 +++++++++++++++++++++++---------------------- 1 file changed, 49 insertions(+), 48 deletions(-) (limited to 'lib') diff --git a/lib/parsetools/src/leex.erl b/lib/parsetools/src/leex.erl index e49032ebe4..942e9928b1 100644 --- a/lib/parsetools/src/leex.erl +++ b/lib/parsetools/src/leex.erl @@ -35,7 +35,7 @@ -export([compile/3,file/1,file/2,format_error/1]). -import(lists, [member/2,reverse/1,sort/1,delete/2, - keysort/2,keydelete/3,keyfind/3, + keysort/2,keydelete/3, map/2,foldl/3,foreach/2,flatmap/2]). -import(string, [substr/2,substr/3,span/2]). -import(ordsets, [is_element/2,add_element/2,union/2]). @@ -58,7 +58,7 @@ gfile=[], % Graph file module, % Module name opts=[], % Options - posix=false, % POSIX regular expressions + % posix=false, % POSIX regular expressions errors=[], warnings=[] }). @@ -136,8 +136,8 @@ format_error({regexp,E})-> "unterminated " ++ Cs;
