~/.local/bin should be added to the PATH environment variable by
default, see

They say that this is specified in the systemd file-hierarchy
specification.  We already ignore most of this specification (see any
entry mentioning /usr, for example).

I think we can safely ignore this specification.

So ~/.local/bin is a relatively recent systemd thing[1], replacing 
the conventional ~/bin.

My theory is that it's intended for users of graphical file 
browsers (where the traditional ~/bin is a bit too prominent even 
for my tastes), but I use it too.

It's trivial to augment $PATH yourself, whether or not your 
distribution is systemd-based.

That link doesn't support adding (or not adding) it.

Adding ~/.local/bin to the PATH is common on other distros.  When
compiling and installing software as a user without making a package
for it, I want to configure it with --prefix=$HOME/.local so I can
install without sudo.  Then I want to be able to run:

myprog

instead of

PATH=$HOME/.local/bin myprog

In particular, I want instructions to work on all distros, even though
Debian failed/fails to do this at the moment too.

This is what still needs to be established: is it?  Which ones? 
Is it merely a side-effect of them using systemd?  And most 
crucially: does it mean that Guix needs to add it too?  What about 
~/bin?

I'm was just interested in the (ideally: your) arguments for doing 
so, not a link to a discussion site.  If it really breaks things 
that should work, I'm all in favour of adding it to the default 
skeleton, if not /etc/profile itself.

You can already easily add custom directories to $PATH in your 
.bash_profile, if my understanding of bash's complicated set of 
configuration files is still accurate.  That's where I set it, 
anyway:

 ~ λ grep PATH= .bash_profile 
 PATH="$HOME/.local/bin:$PATH"

and it's always worked fine.  :-)

Whoa!  This is not a fair summary.  The only ‘bug’ there is that 
Ubuntu (and RHEL's?) *implementation* was buggy, nothing more.

Nowhere is it implied that a distribution not adding .local/bin to 
people's PATH is in any way ’buggy’.

I personally think including $HOME/.local/bin in PATH by default is
unnecessary because the Guix package manager lets non-root users
install packages and installs from source with the --no-substitutes
option. However if some people don't want take the time to write and
debug a package definition for programs they want to install that are
not included in guix by default, installing to $HOME/.local remains a
valid option.

The simplest way to resolve this is probably to include it in the
skeleton folder in your OS definition (flexible design FTW, am I
right?). Maybe there can be a service to allow this option without
everyone who wants it writing the code themselves?

My motivation was that I would have liked a uniform standard to exist
for offering uniform, simple compilation instructions in tutorials
like mine
<https://pelzflorian.de/gui-prog-gtk-2017/handout-05-meson-en.pdf> or
for how-to-install sections in software project README files.  I
therefore believe such standardization efforts should be supported,
even though Guix has good reason to ignore some other aspects of the
file-system hierarchy standard.

I checked now and systemd Parabola iso images and installed systems do
not include ~/.local/bin; neither does an installed Arch system I
looked at, despite their claim to follow
<https://wiki.archlinux.org/index.php/Frequently_asked_questions#Does_Arch_follow_the_Linux_Foundation's_Filesystem_Hierarchy_Standard_(FHS)?>.
I believe this may have to do with their tendency to ship programs
mostly like their upstream developers ship them, which would apply to
GNU Guix as well.  Many other distributions are discussed at my
stackexchange link from before.

I did not know about ~/bin being conventional, but others mention it
too.  I do not like ~/bin for the reasons you stated:

I am not aware of it fixing any breakage, except Python pip according
to the Debian bug report
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=820856> (I did not
try to confirm this), but Guix does not (need to?) have a package for
pip anyway.

Currently for a simple GTK application of mine, on other distros I run
it by

dont-hang

but on Guix I have to run it with:

LD_LIBRARY_PATH=/gnu/store/b9p5rhhci7w1zgvv4j0fm2izk86cgnyd-gtk+-3.24.7/lib:/gnu/store/z7myqdqz5i4ahw57l5hagdkmzwz5g2wv-pango-1.42.4/lib:/gnu/store/5yaa39a8rvq8xdv8h37n29sxfmnlcv12-atk-2.32.0/lib:/gnu/store/4d8rc6vjkhsk1b20rigz0nzl7zffn4b5-cairo-1.16.0/lib:/gnu/store/h7wv1qgpascffzi5xlpagnc0hpiv2523-gdk-pixbuf+svg-2.38.1/lib:/gnu/store/0q9pq9flr76rh4bv2524niknknnl2kvq-glib-2.56.3/lib:$LD_LIBRARY_PATH PATH=$HOME/.local/bin:$PATH dont-hang

Adding ~/.local/bin to the path would remove the small part on the
right.  Patching ninja could probably remove the need for
LD_LIBRARY_PATH.

Specifying the RUNPATH during compilation would allow you to get rid of
LD_LIBRARY_PATH.  What build system are you using?

Hi Florian,

this is not a bug, it's a feature :-)

the "semantic" reason not to include ~/.local/bin in default path is to
clearly state "use Guix" (even on foreign distros) to allow users to
install packages and avoid the ~/<something>/bin _broken_ workaround

IMHO at most ~/.local/bin is useful for user written scripts (but I
prefer ~/bin for mine)

I can't understand what ~/.local/bin have to do with *compilation*: do
you mean installation?

...and AFAIU no distribution on earth install packages (or links) in
~/.local/bin

Guix deploys in ~/.guix-profile/bin/ linking from the store... and it's
awesome :-)

It's easier to add instructions on how to add ~/.local/bin in $PATH, no?
:-)

anyway software projects that want to help users to install (without
root permissions) in a sane way should define a Guix package, no more
workarounds please

[...]

not Guix nor Nix, IMHO it's because they choose to depart from the
problematic FSH and derivatives long time ago and for this reason they
are generally ignored when discussing FSH issues

I don't like ~/.local/bin because it's ".local":

«Care should be taken when placing architecture-dependent binaries in
this place, which might be problematic if the home directory is shared
between multiple hosts with different architectures.»
(from [1])

[...]

last but not least, probably systemd file-hieracy [1] is one of the
*problematic* things of systemd ecosystem we should avoid

...I even ignored the existance of systemd file-hieracy: an init system
defining a filesystem hieracy standard: mumble...




Happy hacking! Gio'.

~/.local/bin is useful for projects at the inception / hacky stage too
or for developers or when they have not been packaged for Guix yet,
but yes, also for user-written scripts.

Only because not all distros respect ~/.local/bin.  I would prefer
ignoring distros that do not respect ~/.local/bin when writing READMEs
rather than complicating READMEs.

Yes; it mixes with the user’s documents.

This is seldom relevant.

This is not a fair argument against ~/.local/bin in PATH.

Yes.  I am using Meson.  I would like instructions like mine

they work on other distros.
