Ticket #219 (reopened defect)

A tab inside a scalar is not accepted

Reported by: py4fun@… Owned by: xi
Priority: normal Component: pyyaml
Severity: normal Keywords:


I got the exception when a tab character (\t) is located inside a scalar:

import yaml


This is the output of the latest source:

  File "C:\projects\py-workspace\pyyaml-trunk\lib\yaml\parser.py", line 143, in parse_implicit_document_start
  File "C:\projects\py-workspace\pyyaml-trunk\lib\yaml\scanner.py", line 116, in check_token
  File "C:\projects\py-workspace\pyyaml-trunk\lib\yaml\scanner.py", line 257, in fetch_more_tokens
    % ch.encode('utf-8'), self.get_mark())
yaml.scanner.ScannerError: while scanning for the next token
found character '\t' that cannot start any token
  in "<string>", line 1, column 4:
    36L	DIESEL

When the tab character is replaced with a space, the parser works properly.

This issue was originally reported for SnakeYAML:  http://code.google.com/p/snakeyaml/issues/detail?id=136

I found the answer in scanner.py

def scan_plain_spaces(self, indent, start_mark):
    # See the specification for details.
    # The specification is really confusing about tabs in plain scalars.
    # We just forbid them completely. Do not use tabs in YAML!

I think PyYAML must allow tabs in plain scalar. I attach the patch with solution for Python 2.x
