Really, not al lthat standard.  It resembles the formatting that the FSF
recommends.  Or once recommended, if I recall correctly.

It's my preferred formatting, too.

There's a longstanding dispute whether to use this one or the one 
used in examples in the old K&R book.  THe dispute will probaby never 
be resolved.

Nice that this also works Xless / on the console:)  Although I am not

PS1 strings Didier posted in this thread on Friday. I could find the
backslash escaped special/characters/  documented in the bash(1)

course returned a lot of results, including several "PS1 generators",
some "Extreme Power Prompt" examples [1] and this extensive "Bash

for a documentation of these powerful escape sequences?

I currently launch tmux on st with this command:

st had the -e option since ages. Some time ago it didn't work properly,

:-)

If it's many colors and a tiny footprint are desired, what I've done is
compiled Suckless Tools' st terminal with many different color
combinations, each with the name 'zz' plus the first letter of the
foreground color plus the first letter of the background color.

Suckless Tools terminals are very low footprint, but they also lack
features necessary for certain tasks. IIRC you'd never use one for a
login terminal, and IIRC they can't be told to run a certain script
(like xterm -e). But they often suffice, and you can easily compile
them to have the exact font size you like.

This approach breaks the moment you ssh from an existing terminal,
especially if you ssh from box 2 to box 3.

I'd instead recommend setting PS1 in .bashrc on those machines to something
distinct.

Here is how I set prompt colors in .bashrc, depending on user:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$

Of course background colour can't be set by this simple way. But note 
that this colour setting is also available in xfce4-terminal and in 
gnome-terminal. BTW, I've read some of ROX's docs and they say many 
applications were forked from Gnome.

I think it depends on the user. The user who would most likely use
Ubuntu, for instance, has little knowledge of package management and
would probably prefer every possible dependency package for every
possible feature be installed.

But for Devuan, and pre 2014 Debian, I'd imagine the average user
would rather the package manager be more conservative in installing
dependencies.

Rox as an environment seems little maintained and quite old, the website says it 
is "RISC OS for X". They had an application-as-folder system and Rox-filer would 
still deal with these if you used them, they called this system zeroinstall 
since it just required copying the self-contained application folder. Probably 
has the same ultimate ancestry as Apple's application folder system.

Hi Simon,

Thanks to your recommendation, I just started using roxterm. What a
breath of fresh air! Tabbed. Multiple profiles mean all sorts of
different terminals for different needs. No unholy union to a "desktop
environment" other than the rox filemanager system.


they are independent, I think ... though perhaps some D&D might be a
bit cleaner between them??? they both just interact with X and allow
extensive file-based configuration if you want to use it. Last time I
tried both worked fine just in X alone, no other management.



I need several different types of terminal emulators for several
different types of jobs. From now on I'm using roxterm instead of
xfce4-terminal for all new construction.


"profiles" can easily be invoked on CL if you want distinctive
appearance to indicate different tasks.


Simon


I installed roxterm and rox-filer. Both are just nice behaving. roxterm doesn't
seem to differ in apearence, configurability or behaviour, from xfce4-terminal
or gnome-terminal.


the main reason I use it instead is that xfce-terminal depends on a desktop 
session, dbus etc to function properly while roxterm does not.


The  second advantage for me (since I use colours to indicate some tasks) is the 
profile/theme configuration is easier to deal with and file based.




rox-filer is nice looking, but it needs some configuration. Here are the two
waek points I noticed

- there is absolutely no application defined by default for any file type; you
must define them all - this is a miss in the packaging.


Here it has  defaults  I think via the MIME system?? but maybe this depends 
on something else being installed? There certainly should be defaults.



- there isn't a menu of possible applications for a given file type. I like to
be able to open an image with either a simple viewer or with Gimp to edit it.


Very easy to add any that you wish, there is a folder of links for each file 
type, and another that fills the 'send to..' menu for every file type.


"Customise Menu.." takes you there, and gives a brief explanation.



And here are some features I like:

- If you left-click with the shift key pressed, you always open the file with
the application you have defined for raw text. This allows to edit an html file
instead of browsing it.

- files are open on single click (double click in Thunar), though this is a
personal preference.

I use aptitude, and of course I use it in the default mode that does 
not automatically install recommendations, in keeping with 
Devuan-style minimalism.  But it doesn't wtop me from wondering why 
other packages are recommended, and whether I might find them useful.

Back in the Debian days, when I installed asciidoc I ended up with 
all of docbook and all of Tex's many packages, which I had no use for, 
since all I needed was to generate HTML  (Why asciidooc? because I 
was working on someone else's project).  I'm pleased wth the Devuan 
defaults.

the reasons are often obscure only because the package descriptions 
are so telegraphic.  Ideally the package manager should be 
organised to let the developer to explain why each of those packages 
had been recommended so that the user can decide.

In this case I'm getting clue.  Zero-install turns out to be a package 
manager, that apparently works compatibly on Linux, Windows, OS X, 
Unix, and in case that isn't enough, also as source code.

Rox is a desktop.  The Rox terminal (recommeded in this thread 
originally) and the Rox file manager are components of Rox, but as we 
see they can easily be used independently.

I suspect that zeroinstall is the native, cross-platform package 
installer that Rox uses, and quite possibly that a lot of the 
file-type handlers for the rox file manager are available as 
zero-install packages.  Stll, I'd like to *know* that instead  of just 
suspecting it.

Zeroinstall can apparently allow users to install packages without 
requiring them to have administrative privileges, can ensure that 
when the same version of the same package is installed by different 
users, only one copy occupies disk space, keep track of which 
users belong with which packages (so they don't get their stuff mixed 
up) and install multiple different versions of one package in case 
users have different constraints because of the curse of 
compatibility.

Annd, to my surprise, the current zeroinstall is written in OCaml, a 
language that's a pretty good tool for writing reliable software.  The 
previous version was apparently written in python.

I'm both surprised and pleased to see OCaml to escape from the 
clutches of logicians and theorem provers into the wider world of 
system programming.  I've always thought that about 90 or more 
percent of the C code in the world could better be written in 
OCaml.  Perhaps there's now someone else that agrees with me.

I too have used rox-filer (but not yet rox-session), and found it the
kind of thing that you could learn to like. I learned of its existence
thanks to Simon's roxterm recommendation, and I'm using rox-filer every
once in a while, and starting to like it more.

With Void Linux some of the filetypes are predefined, but a lot aren't.

Those menus are a double-edged sword. You maneuver thru the whole
thing, don't find the executable you really want, and then have to
furthergui to install an unlisted app.

Nice! Thanks for that tip!

I wouldn't want that for Thunar, but somehow, in rox I like it :-)

Hi Simon,

Thanks to your recommendation, I just started using roxterm. What a
breath of fresh air! Tabbed. Multiple profiles mean all sorts of
different terminals for different needs. No unholy union to a "desktop
environment" other than the rox filemanager system.

they are independent, I think ... though perhaps some D&D might be a
bit cleaner between them??? they both just interact with X and allow
extensive file-based configuration if you want to use it. Last time I
tried both worked fine just in X alone, no other management.



I need several different types of terminal emulators for several
different types of jobs. From now on I'm using roxterm instead of
xfce4-terminal for all new construction.

"profiles" can easily be invoked on CL if you want distinctive
appearance to indicate different tasks.


Simon

 I installed roxterm and rox-filer. Both are just nice behaving.
roxterm doesn't seem to differ in apearence, configurability or
behaviour, from xfce4-terminal or gnome-terminal.

 rox-filer is nice looking, but it needs some configuration. Here
are the two waek points I noticed

 - there is absolutely no application defined by default for any
file type; you must define them all - this is a miss in the
packaging.
 - there isn't a menu of possible applications for a given file
type. I like to be able to open an image with either a simple viewer
or with Gimp to edit it.


So I tried installing it, and found that it recommended zeroinstall-injector.
Anyone know what this is?  It seems to be a "platform-independent
package manager".  What does this mean in relation to rox-filer.  And
how does it relate to apt and aptitude.

Might it alleviate some of the above complaints?

I always use apt-get install --no-install-recommends, or "default 
upgrade" in Synaptic. And I don't look at the recommended packages :-)


This "recommends" feature has become a kind of bin for packages the 
maintainers would like desperately to "require" for obscure reasons, but 
they fail to find a valid one.

Desktop environment/ window manager independent copy'n'paste is another

Yeah, Devuan, Void or practically anywhere else, at this point trying

Of course, on good distros, you don't have to actually start dbus :-)


I've seen a lot of apps that will accept dbus if you want to use it, but do not

communicating with it, and they might then require the lib.

It seems the author may be abandoning it though, which is a pity.

A friend of mine uses don't-know-which distro without dbus.
Everything is easy when you're a lisp-nut and you do the majority of
your computing from inside Emacs.

Libnotify depends on GLib, which under its GIO sub-module has functions
and data objects for telling things to a DBus... bus.
Yeah, GLib reimplements what it should do under libdbus. And C99.
Yeah, something may complain whenever you try to run dunst and
notify-send and dbus isn't up, but the dependency graph of libnotify
not depending on dbus or libdbus is technically correct.

Probably not. My fight is with systemd, not dbus or PulseAudio.
However, the whole systemd episode has made me untrusting of anything
promoted by Freedesktop.Org, so in an ideal world I'd have no dbus.

It might be possible that this dependency is a per-distro thing. The
reason I say that both these commands output nothing on a Void Linux
machine:

[slitt@mydesk ~]$ xbps-query  --fulldeptree -x libnotify | grep -i dbus
[slitt@mydesk ~]$ xbps-query  --fulldeptree -x dunst | grep -i dbus
[slitt@mydesk ~]$

I'm not for a moment suggesting Devuan should remove Debian's libdbus
dependency. We have bigger fish to fry.

Hi all,

dunst is a notification daemon that temporarily gui-prints whatever is
specified by various notify-send commands. Some questions:

Does dunst depend on dbus?
Can dunst be run without dbus?
Can notify-send be run without dbus?

I'd be a lot more open to using notifications if they could be
completely independent of dbus.

Thanks,

Well, according to apt-cache depends, it needs dbus' shared library
(libdbus-1-3).

>Can dunst be run without dbus?
>Can notify-send be run without dbus?

Since it doesn't depend on dbus package, which contains
dbus-daemon, it may be able to.

Not sure, whether having libdbus-1-3 is a concern.
dbus(-dev) is required for building. libdbus-1-3 itself doesn't
needdbus.

>I'd be a lot more open to using notifications if they could be

In case you want to try something else, there are also
statnot [1] and twmn [2].
statnot requires dbus-python for building; twmn
is used in tiling window managers.

From what I understand, all these nofication daemons simply rely on
dbus' shared library but does not require dbus-daemon & Co. to run.
