2019-05-03stdlib: Optimize printing of maps a bitHans Bolinder
2019-02-14stdlib: Optimize formatted printing of termsHans Bolinder
Try calling iolist_size() before calling string:length(). The reason is that calls to string:length/1 are slow when the argument is not a list of integers (or contains UNICODE).
2018-08-20stdlib: Improve error handling in module io_libHans Bolinder
2018-04-25stdlib: Modify the printing of map associations with wWpPHans Bolinder
Use the same depth for all (printed) elements of a map. Since the order of keys can vary when printing a map--maps:iterator/1 and maps:next/1 are used--it is more consistent to print all associations with the same depth. If the associations printed are limited by the depth, the selection of associations is arbitrary, as before.
2018-04-25stdlib: Introduce characters limit of formated stringsHans Bolinder
Inspiration from module lager_format. Also some improvements of Unicode handling. io_lib:format/3 and io_lib:fwrite/3 are new functions. The representation of the options is a list, but we are considering using a map instead. If we change, it will happen after Erlang/OTP 21.0-rc1 is released.
2018-04-25stdlib: Modify ~w/~W when number of characters is limitedHans Bolinder
A bug fix: limited maps end with "...", not "...=>...". A modification: wW separate pairs with " => ", not "=>". When the output is limited on number of characters, the term is balanced by wW the same way as is done with pP (see commit bc38638).
2018-04-25stdlib: io_lib{_pretty}: Avoid tuple_to_list when possibleHans Bolinder
2018-04-25stdlib: Introduce characters limit of formatted stringsHans Bolinder
The name of the io_lib_pretty:print/2 option 'max_chars' is changed to 'line_max_chars' (used by module shell only). The new option for limiting the number of returned characters of io_lib_pretty:print() is called 'chars_limit'.
2018-03-08stdlib: Improve io_lib:limit_term/2Hans Bolinder
Improve handling of maps. Addendum to b57e890.

2017-05-18stdlib: Add io_lib:limit_term/2Hans Bolinder
The term returned by io_lib:limit_term(Term, Depth) should return the same string if substituted for Term in io_lib:format("~P", [Term, Depth]) or io_lib:format("~W", [Term, Depth]).
2017-04-24stdlib: Add Unicode modifier t to control sequences w and WHans Bolinder
As of the introduction of Unicode characters in atoms, the control sequences 'w' and 'W' can return non-Latin-1 characters, unless some measure is taken. This commit makes sure that '~w' and '~W' always return Latin-1 characters, or bytes, which can be output to ports or written to raw files. The Unicode translation modifier 't' is needed to return non-Latin-1 characters.

Using the new type syntax, we can specify which keys are required, and which are optional in a way Dialyzer could use.

2015-03-12stdlib: Enable io_lib:format/* for hamt mapsBjörn-Egil Dahlberg
This is a commit to enable printouts of hashmaps during development and will be enhanced once hashmaps are in place.
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.

files as delimiters. While working on a tool that processes Erlang code and testing it against this repo, I found out about those little sneaky 0xff. I thought it may be of help to other people build such tools to remove non-conforming-to-standard characters.

2013-02-18Add usage of and spec for io:printable_range/0Patrik Nyblom
This makes both io:format("~tp", ...) and the shell honor the +pc setting and also reverts the shell to the old behaviour of only interpreting latin1 strings as "strings" by default. +pc unicode turns on the R16A behaviour. Doing io:format("~tp~n", [[1024,1025]]). will show you the difference when starting with +pc unicode.
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.

Expect modifications, additions and corrections. There is a kludge in file_io_server and erl_scan:continuation_location() that's not so pleasing.

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.
