Install orgmode using its git repository.

Install orgmode using its git repository.

[Hongyi Zhao]

On Ubuntu 20.10, I compiled the latest git master version of emacs,
but I can't the org-mode command from within it. So I try to install
the orgmode using its git repository according to the guidance [1] as
shown below.

$ git clone https://code.orgmode.org/bzg/org-mode.git
Public/repo/code.orgmode.org/bzg/org-mode.git
$ cd code.orgmode.org/bzg/org-mode.git
$ make autoloads

Then add the following lines into ~/.emacs.d/init.el:

(add-to-list 'load-path "~/Public/repo/code.orgmode.org/bzg/org-mode.git/lisp")
(add-to-list 'load-path
"~/Public/repo/code.orgmode.org/bzg/org-mode.git/contrib/lisp" t)

But after I started emacs and issue the instructions 'M-x org- RET', I
see the following information in the minibuffer:

Possible completions are:
org-decrypt-entries     org-decrypt-entry
org-encrypt-entries     org-encrypt-entry

As you can see, the org-mode is still not available. Any hints for
solving this problem is highly appreciated.

BTW, you can also install the latest code from Git via package.el:

    M-x url-handler-mode RET       ;; Assuming it's not already enabled
    C-x C-f https://elpa.gnu.org/devel/org.tar RET
    M-x package-install-from-buffer RET

If I want to implement the above codes as a package-install-from-repo
function with the pakcage's URL as the argument, then how should I
rewrite the above code?

Not sure what you're asking.  Such a function would be a welcome
addition to package.el, if that's what you mean.

I just noticed that this question has been discussed on stackexchange:

Sv: Install orgmode using its git repository.

[arthur miller]

I don't think it is very safe practice to install random Joe's code directly from
some git repo. We have not yet seen malicious code (not what I know) in
Emacs community, but Emacs in that respect is as bad as MS Office from
time when VBA scripts (and viruses) were shared wildly around, or a web
browserwith JS that can do anything. Remember time when JS was off by default
in all browsers?  Elisp can do whatever on your computer, so you should be
careful what you install. Installing from random git repos can open you for
more security problems then needed. I do clone lots from gitlab/github, but
I always look at the code myself before I ever run it.

Another point is that installing from git and different branches as it is possible
with straight.el  or quelpa (is what OP actually wants)  can eventually lead to
incompatibility between code that might be much harder to detect. I personally
don't want to  bother with latest-latest of all latest because eventually it could
become a spagheti code of possible incompatibility and clashes.

FWIW, the function could/should obey `package-check-signature`.

You can address these points in multiple ways:

1. A good backup and restore strategy
2. Virtual machines (ie a chromebook)
3. prioritize (m)elpa-stable over (m)elpa
4. el-get can get particular version from git

Nöje of that you write is particularly adequate "addressing" of potential security vulnerability that let's potential malicious code 1) install anything on  your machine 2) steal your data 3) destroy your data.

Maybe a virtual machine, but then you wouldn't be running your Emacs for anything  sensitive or serious.

A reviewed package from elpa/helps gives at least some guarantee that you are not getting binary blobs and/or directly malicious code installed on your machine.

Actually, *nix systems have a very good way to handle these kinds of
threats without resort to such devices: users and groups. One can create
a user account with very limited privileges for working with unvetted
code, data, etc.

Actually, I do this for developing new code, too. That way, whatever I
break/change is contained within the confines of that account.

RE: Sv: Install orgmode using its git repository.

[arthur miller]

I won't say anything about nix; it probably is very good and flexible system. I am also sure containers (docker, kubernetes etc) could be utilized to sandbox Emacs and what not. But I don't think it should not be mandatory. Emacs should run safe on bare metal.

However it is all personal. People can do whatever they want with their computers, and there are already solutions that integrate random github repos: quelpa and straight. But it is still individuals own initiative to use those. I don't Emacs should have that built in.

In my opinion it opens for more security risks then needed, and also for possibility to very easy distribute binary blobs not compatible with GPL. It is not very difficult to get in those in Emacs now either, but at least it takes individual's own actions and is not automated from Emacs out of the box.

Re: Sv: Install orgmode using its git repository.

[Robert Thorpe]

For what it's worth, I agree with Arthur.

I'd point out that this sort of thing has happened before.  A Python
package called "Colourama" was found to be manipulating bitcoin
addresses.  When you put a bitcoin address into the clipboard it would
intercept it and replace it with a different one.  Notice the British
spelling, the legitimate package was called "Colorama".  The "Colourama"
package was a minor derivative with the bitcoin address trick added in.

Something similar happened to the NPM Javascript library.

We also have to remember that there's the possibility of people hacking
things like github.  Or obtaining the credentials of github users and
their signing keys.  The recent problems at the US DoD were caused by
Solarwinds software.  The hackers got into the Solarwinds source code
repository (due to very lax security, github & gitlab are probably
better).  Once in the repository they made a few changes to the
sourcecode to introduce a backdoor.

As a result, I'm fairly wary of this idea of automatic downloading.  On
the other hand, for many packages it's hardly practical to read the
whole sourcecode no matter how you obtain it.

Elisp, just as any lisp derivatives, has a very steep learning curve.
They all have a fairly simple grammatical structure at the first
glimpse but it is so difficult to master and use them skillfully.

RE: Sv: Install orgmode using its git repository.

[arthur miller]

Also if it is only for the org, one can add org package archive and fetch it via package.el already. I use to do it, so bare git access is certainly not mandatory to install latest org, if one that comes with Emacs is not enough.

Actually, *nix systems have a very good way to handle these kinds of
threats without resort to such devices: users and groups. One can create
a user account with very limited privileges for working with unvetted
code, data, etc.

Actually, I do this for developing new code, too. That way, whatever I
break/change is contained within the confines of that account.

Docker is more excellent option for this sort of job.

That's not quite the same question, actually.
What I was referring to is a function which lets you install a particular
ELPA package by giving a URL to it.  This usually won't allow you to
install a package directly from its Git repository (tho it may work in
some particular cases).

I believe/hope this is a bug that was already fixed on the emacs-27
branch, and hopefully will be merged to master soon.

Sv: Install orgmode using its git repository.

[arthur miller]

I use to install org via use-package, just org repository to package. Then I also use to use something:
I use to remove built-in org directory from emacs source and symlink to latest org-source. Worked
well too. The thing is when running Emacs with -Q then org would not be present. I don't need latest
features, so I don't  really care to do that any more.

Ämne: Install orgmode using its git repository.

On Ubuntu 20.10, I compiled the latest git master version of emacs,
but I can't the org-mode command from within it. So I try to install
the orgmode using its git repository according to the guidance [1] as
shown below.

$ git clone https://code.orgmode.org/bzg/org-mode.git
Public/repo/code.orgmode.org/bzg/org-mode.git
$ cd code.orgmode.org/bzg/org-mode.git
$ make autoloads

Then add the following lines into ~/.emacs.d/init.el:

(add-to-list 'load-path "~/Public/repo/code.orgmode.org/bzg/org-mode.git/lisp")
(add-to-list 'load-path
"~/Public/repo/code.orgmode.org/bzg/org-mode.git/contrib/lisp" t)

But after I started emacs and issue the instructions 'M-x org- RET', I
see the following information in the minibuffer:

Possible completions are:
org-decrypt-entries     org-decrypt-entry
org-encrypt-entries     org-encrypt-entry

As you can see, the org-mode is still not available. Any hints for
solving this problem is highly appreciated.
