From 5025e10a003d5ce73d845e89a1638a626ab52fa4 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 26 Sep 2007 17:14:16 +0800 Subject: [PARSER] Recognise here-doc delimiters terminated by EOF Previously dash required a character to be present in order for a here-document delimiter to be detected. Allowing EOF in the absence of a to play the same purpose allows some intuitive scripts to succeed. POSIX seems to be silence on this so this should be OK. Test case: eval 'cat <<- NOT test NOT' echo OK Old result: test NOTOK New result: test OK --- src/parser.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/parser.c b/src/parser.c index 1a483d4..cac0aa5 100644 --- a/src/parser.c +++ b/src/parser.c @@ -1049,8 +1049,14 @@ checkend: { char *p, *q; p = line; - for (q = eofmark + 1 ; *q && *p == *q ; p++, q++); - if (*p == '\n' && *q == '\0') { + for (q = eofmark + 1;; p++, q++) { + c = *p; + if (c == '\n') + c = 0; + if (!*q || c != *q) + break; + } + if (c == *q) { c = PEOF; plinno++; needprompt = doprompt; -- cgit 1.4.1
