Fix the regex comments describing what we parse as JSON. No change to the lexer itself, just to the comments: - The "" and '' string construction was missing alternation between different escape sequences - The construction for numbers forgot to handle optional leading '-' - The construction for numbers was grouped incorrectly so that it didn't permit '0.1' - The construction for numbers forgot to mark the exponent as optional - No mention that our '' string and "\'" are JSON extensions - No mention of our %d and related extensions when constructing JSON Signed-off-by: Eric Blake <eblake@redhat.com> --- qobject/json-lexer.c | 21 ++++++++++++++++----- 1 file changed, 16 insertions(+), 5 deletions(-)
