New submission from Ferdinand Beyer:
The linecol() function in json/decoder.py computes the line and column numbers
for a byte offset in a string. Both numbers are expected to start with 1 (as
in text editors).
If the position is in the first line, the returned column is off by one (or
starting with zero):
>>> from json.decoder import linecol
>>> linecol('spam', 0) # Should be (1, 1)
(1, 0)
>>> linecol('\nspam', 1)
(2, 1)
The problem is the line:
if lineno == 1:
colno = pos
that should read
if lineno == 1:
colno = pos + 1
