pixd is a tool for visualizing binary data using a colour palette. It is in
a lot of ways akin to a hexdump tool, except using coloured squares to
represent each octet.
pixd uses 24-bit color SGR escape sequences. For a list of terminal emulators
with support for these, see XVilka's list of supporting terminal emulators:
https://gist.github.com/XVilka/8346728
hexd prints a human-readable hexdump of the specified files, or standard
input if omitted. Its main distinguishing feature is the use of colours to
visually indicate which range of values an octet belongs to, aiding in
spotting patterns in binary data.
By default, hexd relies on 256-color SGR escape sequences. Most terminal
emulators should support these today, but technically they're only defacto
standard. However, you can override the formatting used with the HEXD_COLORS
environment variable (see manpage), or use the -p option for plaintext
output.
You're writing a library. You've decided to be ambitious, and support multiple
async I/O packages, like Trio, and asyncio, and... You've written a bunch of
clever code to handle all the differences. But... how do you know which piece of
clever code to run?
This is a tiny package whose only purpose is to let you detect which async
library your code is running under.
An immutable mapping type for Python.
The underlying datastructure is a Hash Array Mapped Trie (HAMT) used in
Clojure, Scala, Haskell, and other functional languages. This implementation is
used in CPython 3.7 in the contextvars module (see PEP 550 and PEP 567 for more
details).
Immutable mappings based on HAMT have O(log N) performance for both set() and
get() operations, which is essentially O(1) for relatively small mappings.
Changes from 2.1:
Clean up some b'' quoting that appeared around strings in the log
output under python3.
New command line option --image-format for selecting the guest disk
image format. Supported values are "dense" (the default) and
"sparse".
Reset the install timeout whenever a new set extraction or other
command is started by sysinst, and reduce the timeout to 1 hour.
This allows hangs in the install phase to be detected more quickly.
Reset the test timeout whenever a new test program is started by ATF,
and reduce the default timeout to 2 hours. If you are passing a
non-default test timeout with the --test-timeout option, it can also
be reduced. This allows hangs during test runs to be detected more
quickly.
Fix the sparc64 CD install which was broken in 2.1, by adding an
index=2 attribute to the virtual CD drive.
Make NetBSD-current/macppc boot by passing "-prom-env qemu_boot_hack=y"
to qemu-system-ppc. From Joerg Sonnenberger.
A library of extra functions for the standard Haskell libraries. Most
functions are simple additions, filling out missing functionality. A
few functions are available in later versions of GHC, but this package
makes them available back to GHC 7.2.
pkgsrc changes:
- Remove no longer needed patch applied upstream
Changes:
CHANGES FROM 3.0 to 3.0a
* Do not require REG_STARTEND.
* Respawn panes or windows correctly if default-command is set.
* Add missing option for after-kill-pane hook.
* Fix for crash with a format variable that doesn't exist.
* Do not truncate list-keys output on some platforms.
* Do not crash when restoring a layout with only one pane.
CHANGES FROM 2.9 to 3.0
* Workaround invalid layout strings generated by older tmux versions and add
some additional sanity checks
* xterm 348 now disables margins when resized, so send DECLRMM again after
resize.
* Add support for the SD (scroll down) escape sequence.
* Expand arguments to C and s format modifiers to match the m modifier.
* Add support for underscore colours (Setulc capability must be added with
terminal-overrides as described in tmux(1)).
* Add a "fill" style attribute for the fill colour of the drawing area (where
appropriate).
* New -H flag to send-keys to send literal keys.
* Format variables for pane mouse modes (mouse_utf8_flag and mouse_sgr_flag)
and for origin mode (origin_flag).
* Add -F to refresh-client for flags for control mode clients, only one flag
(no-output) supported at the moment.
* Add a few vi(1) keys for menus.
* Add pane options, set with set-option -p and displayed with show-options -p.
Pane options inherit from window options (so every pane option is also
a window option). The pane style is now configured by setting window-style
and window-active-style in the pane options; select-pane -P and -g now change
the option but are no longer documented.
* Do not document set-window-option and show-window-options. set-option -w and
show-options -w should be used instead.
* Add a -A flag to show-options to show parent options as well (they are marked
with a *).
* Resize panes lazily - do not resize unless they are in an attached, active
window.
* Add regular expression support for the format search, match and substitute
modifiers and make them able to ignore case. find-window now accepts -r to
use regular expressions.
* Do not use $TMUX to find the session because for windows in multiple sessions
it is wrong as often as it is right, and for windows in one session it is
pointless. Instead use TMUX_PANE if it is present.
* Do not always resize the window back to its original size after applying a
layout, keep it at the layout size until it must be resized (for example when
attached and window-size is not manual).
* Add new-session -X and attach-session -x to send SIGHUP to parent when
detaching (like detach-client -P).
* Support for octal escapes in strings (such as \007) and improve list-keys
output so it parses correctly if copied into a configuration file.
* INCOMPATIBLE: Add a new {} syntax to the configuration file. This is a string
similar to single quotes but also includes newlines and allows commands that
take other commands as string arguments to be expressed more clearly and
without additional escaping.
A literal { and } or a string containing { or } must now be escaped or
quoted, for example '{' and '}' instead of { or }, or 'X#{foo}' instead of
X#{foo}.
* New <, >, <= and >= comparison operators for formats.
* Improve escaping of special characters in list-keys output.
* INCOMPATIBLE: tmux's configuration parsing has changed to use yacc(1). There
is one incompatible change: a \ on its own must be escaped or quoted as
either \\ or '\' (the latter works on older tmux versions).
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
* Add support for the overline attribute (SGR 53). The Smol capability is
needed in terminal-overrides.
* Add the ability to create simple menus. Introduces new command
display-menu. Default menus are bound to MouseDown3 on the status line;
MouseDown3 or M-MouseDown3 on panes; MouseDown3 in tree, client and
buffer modes; and C-b C-m and C-b M-m.
* Allow panes to be empty (no command). They can be created either by piping to
split-window -I, or by passing an empty command ('') to split-window. Output
can be sent to an existing empty window with display-message -I.
* Add keys to jump between matching brackets (emacs C-M-f and C-M-b, vi %).
* Add a -e flag to new-window, split-window, respawn-window, respawn-pane to
pass environment variables into the newly created process.
* Hooks are now stored in the options tree as array options, allowing them to
have multiple separate commands. set-hook and show-hooks remain but
set-option and show-options can now also be used (show-options will only show
hooks if given the -H flag). Hooks with multiple commands are run in index
order.
* Automatically scroll if dragging to create a selection with the mouse and the
cursor reaches the top or bottom line.
* Add -no-clear variants of copy-selection and copy-pipe which do not clear the
selection after copying. Make copy-pipe clear the selection by default to be
consistent with copy-selection.
* Add an argument to copy commands to set the prefix for the buffer name, this
(for example) allows buffers for different sessions to be named separately.
* Update session activity on focus event.
* Pass target from source-file into the config file parser so formats in %if
and %endif have access to more useful variables.
* Add the ability to infer an option type (server, session, window) from its
name to show-options (it was already present in set-option).

----------------------------------------------------------------
* Noteworthy changes in release 8.31 (2019-03-10) [stable]
** Bug fixes
'base64 a b' now correctly diagnoses 'b' as the extra operand, not 'a'.
[bug introduced in coreutils-5.3.0]
When B already exists, 'cp -il A B' no longer immediately fails
after asking the user whether to proceed.
[This bug was present in "the beginning".]
df no longer corrupts displayed multibyte characters on macOS.
[bug introduced with coreutils-8.18]
seq no longer outputs inconsistent decimal point characters
for the last number, when locales are misconfigured.
[bug introduced in coreutils-7.0]
shred, sort, and split no longer falsely report ftruncate errors
when outputting to less-common file types. For example, the shell
command 'sort /dev/null -o /dev/stdout | cat' no longer fails with
an "error truncating" diagnostic.
[bug was introduced with coreutils-8.18 for sort and split, and
(for shared memory objects only) with fileutils-4.1 for shred]
sync no longer fails for write-only file arguments.
[bug introduced with argument support to sync in coreutils-8.24]
'tail -f file | filter' no longer exits immediately on AIX.
[bug introduced in coreutils-8.28]
'tail -f file | filter' no longer goes into an infinite loop
if filter exits and SIGPIPE is ignored.
[bug introduced in coreutils-8.28]
** Changes in behavior
cksum, dd, hostid, hostname, link, logname, sleep, tsort, unlink,
uptime, users, whoami, yes: now always process --help and --version options,
regardless of any other arguments present before any optional '--'
end-of-options marker.
nohup now processes --help and --version as first options even if other
parameters follow.
'yes a -- b' now outputs 'a b' instead of including the end-of-options
marker as before: 'a -- b'.
echo now always processes backslash escapes when the POSIXLY_CORRECT
environment variable is set.
When possible 'ln A B' now merely links A to B and reports an error
if this fails, instead of statting A and B before linking. This
uses fewer system calls and avoids some races. The old statting
approach is still used in situations where hard links to directories
are allowed (e.g., NetBSD when superuser).
ls --group-directories-first will also group symlinks to directories.
'test -a FILE' is not supported anymore. Long ago, there were concerns about
the high probability of humans confusing the -a primary with the -a binary
operator, so POSIX changed this to 'test -e FILE'. Scripts using it were
already broken and non-portable; the -a unary operator was never documented.
wc now treats non breaking space characters as word delimiters
unless the POSIXLY_CORRECT environment variable is set.
** New features
id now supports specifying multiple users.
'date' now supports the '+' conversion specification flag,
introduced in POSIX.1-2017.
printf, seq, sleep, tail, and timeout now accept floating point
numbers in either the current or the C locale. For example, if the
current locale's decimal point is ',', 'sleep 0,1' and 'sleep 0.1'
now mean the same thing. Previously, these commands accepted only
C-locale syntax with '.' as the decimal point. The new behavior is
more compatible with other implementations in non-C locales.
test now supports the '-N FILE' unary operator (like e.g. bash) to check
whether FILE exists and has been modified since it was last read.
env now supports '--default-signal[=SIG]', '--ignore-signal[=SIG]', and
'--block-signal[=SIG], to setup signal handling before executing a program.
env now supports '--list-signal-handling' to indicate non-default
signal handling before executing a program.
** New commands
basenc is added to complement existing base64,base32 commands,
and encodes and decodes printable text using various common encodings:
base64,base64url,base32,base32hex,base16,base2,z85.
** Improvements
ls -l now better aligns abbreviated months containing digits,
which is common in Asian locales.
stat and tail now know about the "sdcardfs" file system on Android.
stat -f -c%T now reports the file system type, and tail -f uses inotify.
stat now prints file creation time when supported by the file system,
on GNU Linux systems with glibc >= 2.28 and kernel >= 4.11.
----------------------------------------------------------------
* Noteworthy changes in release 8.30 (2018-07-01) [stable]
** Bug fixes
'cp --symlink SRC DST' will again correctly validate DST.
If DST is a regular file and SRC is a symlink to DST,
then cp will no longer allow that operation to clobber DST.
Also with -d, if DST is a symlink, then it can always be replaced,
even if it points to SRC on a separate device.
[bugs introduced with coreutils-8.27]
'cp -n -u' and 'mv -n -u' now consistently ignore the -u option.
Previously, this option combination suffered from race conditions
that caused -u to sometimes override -n.
[bug introduced with coreutils-7.1]
'cp -a --no-preserve=mode' now sets appropriate default permissions
for non regular files like fifos and character device nodes etc.,
and leaves mode bits of existing files unchanged.
Previously it would have set executable bits on created special files,
and set mode bits for existing files as if they had been created.
[bug introduced with coreutils-8.20]
'cp --remove-destination file symlink' now removes the symlink
even if it can't be traversed.
[bug introduced with --remove-destination in fileutils-4.1.1]
ls no longer truncates the abbreviated month names that have a
display width between 6 and 12 inclusive. Previously this would have
output ambiguous months for Arabic or Catalan locales.
'ls -aA' is now equivalent to 'ls -A', since -A now overrides -a.
[bug introduced in coreutils-5.3.0]
'mv -n A B' no longer suffers from a race condition that can
overwrite a simultaneously-created B. This bug fix requires
platform support for the renameat2 or renameatx_np syscalls, found
in recent Linux and macOS kernels. As a side effect, ‘mv -n A A’
now silently does nothing if A exists.
[bug introduced with coreutils-7.1]
** Changes in behavior
'cp --force file symlink' now removes the symlink even if
it is self referential.
ls --color now matches file extensions case insensitively.
** New features
cp --reflink now supports --reflink=never to enforce a standard copy.
env supports a new -v/--debug option to show verbose information about
each processing step.
env supports a new -S/--split-string=S option to split a single argument
string into multiple arguments. Used to pass multiple arguments in scripts
(shebang lines).
md5sum accepts a new option: --zero (-z) to delimit the output lines with a
NUL instead of a newline character. This also disables file name escaping.
This also applies to sha*sum and b2sum.
rm --preserve-root now supports the --preserve-root=all option to
reject any command line argument that is mounted to a separate file system.
** Improvements
cut supports line lengths up to the max file size on 32 bit systems.
Previously only offsets up to SIZE_MAX-1 were supported.
stat and tail now know about the "exfs" file system, which is a
version of XFS. stat -f --format=%T now reports the file system type,
and tail -f uses inotify.
wc avoids redundant processing of ASCII text in multibyte locales,
which is especially significant on macOS.
The Plasma help system is designed to make accessing the common
UNIX help systems (man and info) simple, as well as the native
Plasma and applications documentation (XML).
