[erlang-bugs] Parser bug: if missing ", " in list between records, the first is ignored, and no parser warnings are given.

[Mattias Waldau]

This is the program

-module('missing-comma-not-detected').

-export([data/1]).

-compile(export_all).

-record(shcnode, {
       nodename :: any(),
       y_axis :: number(),
       children :: [any()],
       article_number :: number(),
       attribute_condition :: string()}).


data(1) ->
     [
      #shcnode{nodename = start, y_axis = 0, children = [d1285]},
      #shcnode{nodename = d1285, y_axis = 295, children = [1939, 1940]}
      #shcnode{nodename = 1940, y_axis = 525, children = [bm3203], 
article_number = 14432861},
      #shcnode{nodename = 1939, y_axis = 530, children = [bm3203], 
article_number = 14432860},
      #shcnode{nodename = bm3203, y_axis = 915, children = []}
     ].


Note the missing "," after  [1939, 1940]}

Only 4 rows are detected

length('missing-comma-not-detected':data(1)).
4

---

If I add the comma, I get

length('missing-comma-not-detected':data(1)).
5

----

I am using Erlang 17.3 on ubuntu.

erlang:system_info(otp_release).
"17"

36> |erl -V
Eshell V6.2  (abort with ^G)
1> |

Thanks,

Mattias
