From 592f2dbd82c6cb9f85332c8056eed58374ac6dd0 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Wed, 16 May 2012 00:18:16 +0200 Subject: [PATCH] sh/jshn.sh: allow numbers in identifiers for json_get_var() When traversing arrays of tables or arrays of array it is required to call json_select # where # is the index of the array item to select. Internally json_select() calls json_get_var() to obtain the correct prefix to populate $JSON_CUR with. However, the "tr" call in json_get_var() incorrectly replaces all digits with underscores, making any lookup for numeric array items fail. The attached patch changes the "tr" expression to allow digits and thus implements the expected behaviour for nested arrays. --- sh/jshn.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sh/jshn.sh b/sh/jshn.sh index 117da67..7228adf 100644 --- a/sh/jshn.sh +++ b/sh/jshn.sh @@ -100,7 +100,7 @@ json_get_type() { json_get_var() { local dest="$1" - local var="$(echo -n "$2" | tr -C '[a-zA-Z_]' _)" + local var="$(echo -n "$2" | tr -C '[a-zA-Z0-9_]' _)" eval "export -- \"$dest=\${${JSON_CUR}_$var}\"" } -- 2.11.0
