The previous detection per get_screen_size fails when stdout is passed
to a pipe. That is the case when running ruby tests in parallel ("-j" switch).
In this case Reline believes that it's running on MinTTY and the tests
are running with ANSI IOGate instead of the Windows adapter on MINGW.
So parallel test results were different to that of a single process.
This commit fixes these differencies.
The code is taken from git sources and translated to ruby.
NtQueryObject() is replaced by GetFileInformationByHandleEx(), because
NtQueryObject() is undocumented and is more difficult to use:
c5a03b1e29/compat/winansi.c (L558)
The command prompt on Windows always uses Unicode to take input and print
output but most Reline implementation depends on Encoding.default_external.
This commit introduces an abstracted structure about the encoding of Reline.
The function getwch() returns some key sequences which start from 0 or 0xE0
with a following key code. Alt+` that is on/off key for input methods gives 0
and 41 so Reline was always ignoring 0 and following keys but numeric keypad
keys give 0 and following actual keys. This commit changes the behavior to be
ignoring only the 0 and 41 sequence.
typedef struct _COORD {
SHORT X;
SHORT Y; // I wanted to take this...
} COORD, *PCOORD;
typedef struct _CONSOLE_SCREEN_BUFFER_INFO {
COORD dwSize;
COORD dwCursorPosition; // ...of this one
WORD wAttributes; // But it's combined with first 2bytes of this
SMALL_RECT srWindow;
COORD dwMaximumWindowSize;
} CONSOLE_SCREEN_BUFFER_INFO;
If wAttributes has non-zero value, the code breaks.
* lib/reine.rb, lib/reline/*: Reline is a readline stdlib compatible
library.
* lib/readline.rb: Readline uses a fallback to Reline when ext/readline
doesn't exist.
* tool/sync_default_gems.rb: add ruby/reline as a default gem.
* appveyor.yml: add "set RELINE_TEST_ENCODING=Windows-31J" for test suit
of Reline, and add "--exclude readline" to "nmake test-all" on Visual
Studio builds because of strange behavior.
* spec/ruby/library/readline/spec_helper.rb: skip Reline as with
RbReadline.
Reline is a readline stdlib compatible library. It also supports
multiline input. IRB is improved with Reline and supports multiline.
Besides, supports showing documents when completed.
