2015-03-10Make the scanned form of the io_lib format strings available for processingRichard Carlsson
This adds three new functions to io_lib - scan_format/2, unscan_format/1, and build_text/1 - which expose the parsed form of the format control sequences to make it possible to easily modify or filter the input to io_lib:format/2. This can e.g. be used in order to replace unbounded-size control sequences like ~w or ~p with corresponding depth-limited ~W and ~P before doing the actual formatting.
2014-09-19Optimise io requests for long message queuesMagnus Henoch
Ensure that the monitor reference is present in all receive clauses, so that the compiler optimisation kicks in and the run time won't depend on the length of the message queue of the calling process. Remove the 'EXIT' clause, as its presence breaks the optimisation, and that case is handled by the 'DOWN' clause anyway. The test io_SUITE:io_with_huge_message_queue is an adaptation of gen_server_SUITE:call_with_huge_message_queue.
2014-05-20Properly handle fields too short in io_lib_formatAnthony Ramine
Values for which the precision or field width were too small in io_lib_format could trigger an infinite loop or crash in term/5. Reported-by: Richard Carlsson
2013-04-19Remove the "coding: utf-8" comment from all Erlang source filesHans Bolinder
2013-02-19Adapt stdlib tests to ~tp detecting latin1 binariesPatrik Nyblom
2013-02-18Correct misspelled comments and space at lin endsPatrik Nyblom
2013-02-18Add testcase for +pc and io:printable_range/0Patrik Nyblom
Also fixed otp_10302 to test both on a node with +pc unicode and a node with +pc latin1.
2013-02-15[stdlib] Add control sequence modifier 'l'Hans Bolinder
The modifier 'l' can be used for turning off the string recognition of ~p and ~P.
2013-02-13Extend ~ts to handle binaries with characters coded in ISO-latin-1Hans Bolinder
Make sure io_lib:fwrite() with a format string including "~ts" does not crash when given binaries that cannot be interpreted as UTF-8-encoded strings. We want to avoid crashes caused by excessive use of the 't' modifier.
2013-02-11[stdlib] Fix a bug concerning pretty printing and UnicodeHans Bolinder
Binaries were pretty printed too often.
2013-01-25Extend char() to Unicode charactersHans Bolinder
The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.
2013-01-09Prepare OTP files for Unicode as default encodingHans Bolinder
2013-01-02[stdlib, kernel] Introduce Unicode support for Erlang source filesHans Bolinder
Expect modifications, additions and corrections. There is a kludge in file_io_server and erl_scan:continuation_location() that's not so pleasing.
2012-09-19Fix printing the empty binary at depth 1 with ~WAndrew Thompson
A case clause ordering problem is causing the empty binary to be printed as <<...>> rather than the correct <<>> when using ~W with a depth of 1. Add new tests to verify correct behaviour.
