bpo-32892: Use ast.Constant instead of specific constant AST types. (GH-9445) 2018-09-27 17:42:37 +03:00
Łukasz Langa e7c566caf1 bpo-30465: Fix lineno and col_offset in fstring AST nodes (#1800)
For f-string ast nodes, fix the line and columns so that tools such as flake8 can identify them correctly.

ericvsmith 11e97f2f80 bpo-30682: Removed a too-strict assertion that failed for certain f-strings. (#2232)
This caused a segfault on eval("f'\\\n'") and eval("f'\\\r'") in debug build.

Serhiy Storchaka 2e9cd5825c bpo-30529: Fix errors for invalid whitespaces in f-string subexpressions. (#1888)
'invalid character in identifier' now is raised instead of
'f-string: empty expression not allowed' if a subexpression contains
only whitespaces and they are not accepted by Python parser.

Serhiy Storchaka 0cd7a3f196 bpo-29104: Fixed parsing backslashes in f-strings. (#490) 2017-05-25 13:33:55 +03:00
Serhiy Storchaka 4cc30ae313 Issue #28739: f-string expressions no longer accepted as docstrings and
by ast.literal_eval() even if they do not include subexpressions.

Eric V. Smith 9b88fdf4f0 Fixed issue #28633: segfault when concatenating bytes literal and f-string. 2016-11-07 17:54:01 -05:00
Jason R. Coombs 1c92a76a69 Update test_no_escapes_for_braces to clarify behavior with a docstring and expressions that clearly are not evaluated. 2016-11-06 11:25:54 -05:00
Jason R. Coombs da25abf712 Additionally show that a backslash-escaped opening brace is treated as a literal and thus triggers the single closing brace error, clarifying #28590. 2016-11-06 11:14:48 -05:00
Jason R. Coombs 45cab8ccdd Add an additional test with a newline, one that's very similar to test_parens_in_expressions, but because the newline is not a literal newline, but a backslash en, this error is triggered. 2016-11-06 11:01:08 -05:00
Serhiy Storchaka 13c8f3266a Update the f-string test broken in issue #28385. 2016-10-31 08:13:00 +02:00
Eric V. Smith 35a24c5a43 Add another f-string comment test, to make sure # are being caught in the right place. 2016-09-11 19:01:22 -04:00
Eric V. Smith 09835dcdbb Make an f-string error message more exact and consistent. 2016-09-11 18:58:20 -04:00
Eric V. Smith 451d0e38fc Issue 27948: Allow backslashes in the literal string portion of f-strings, but not in the expressions. Also, require expressions to begin and end with literal curly braces. 2016-09-09 21:56:20 -04:00
Eric V. Smith 6a4efce7a5 Closes issue 27921: Disallow backslashes anywhere in f-strings. This is a temporary restriction. In 3.6 beta 2, the plan is to again allow backslashes in the string parts of f-strings, but disallow them in the expression parts. 2016-09-03 09:18:34 -04:00
Martin Panter 263893c261 Issue #27626: Further spelling fixes for 3.6 2016-07-28 01:25:31 +00:00
Eric V. Smith 135d5f49f6 Fix issue 26287: While handling FORMAT_VALUE opcode, the top of stack was being corrupted if an error occurred in PyObject_Format(). 2016-02-05 18:23:08 -05:00
Eric V. Smith b2080f6554 f-strings: More tests for empty expressions along with missing closing braces. 2015-09-23 10:24:43 -04:00
Eric V. Smith 548c4d3178 Added more f-string test for empty expressions. 2015-09-23 08:00:01 -04:00
Eric V. Smith 1d44c41b0c Move f-string compilation of the expression earlier, before the conversion character and format_spec are checked. This allows for error messages that more closely match what a user would expect. 2015-09-23 07:49:00 -04:00
Eric V. Smith 235a6f0984 Issue #24965: Implement PEP 498 "Literal String Interpolation". Documentation is still needed, I'll open an issue for that. 2015-09-19 14:51:32 -04:00
