Symbol's function definition is void: mathpix-app-id

Symbol's function definition is void: mathpix-app-id

[Hongyi Zhao]

I try to test the mathpix.el package located at
<https://github.com/jethrokuan/mathpix.el>, using Emacs git master
version on Ubuntu 20.04 with the following methods:

# Clone the github repo:
$ cd .emacs.d/elpa
$ git clone https://github.com/jethrokuan/mathpix.el.git mathpix.el.git

Add the following code snippet into ~/.emacs.d/init.el:

(load-file "~/.emacs.d/elpa/mathpix.el.git/mathpix.el")
(mathpix-app-id "app_id")
(mathpix-app-key "app_key")

Start Emacs and run the following command to do the test:

"M-x mathpix-screenshot RET"

Then I meet the following error:

Warning (initialization): An error occurred while loading
‘/home/apollo/.emacs.d/init.el’:

Symbol's function definition is void: mathpix-app-id

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace. Disable
showing Disable logging

Any hints for fixing this problem?

(load-file "~/.emacs.d/elpa/mathpix.el.git/mathpix.el")
(mathpix-app-id "app_id")
(mathpix-app-key "app_key")

At first place in a list within parenthesis comes the instruction on
what to do with the list:

Recommended is to evaluate the below:
(info "(eintr) Run a Program")

As in this case `mathpix-app-id' should be instruction to evaluate
something. That instruction is defined as a function usually.

(mathpix-app-id "app_id")

Because the function `mathpix-app-pid' does not exist, there is error.

Instead, what you need most probably is:

(setq mathpix-app-id "app_id")

as then the instruction `set' or "Set quoted" means to assign the
value "app_id" to variable `mathpix-app-id'.

According to your above comment, I adopt with the following settings:

(load-file "~/.emacs.d/elpa/mathpix.el.git/mathpix.el")
(setq mathpix-app-id "my_app_id")
(setq mathpix-app-key "my_app_key")

But I still can't do the conversion successfully and will meet the
following info in the *Messages* buffer:

Public/repo/github.com/jwiegley/use-package.git/bind-key.el: Warning:
Use keywords rather than deprecated positional arguments to
`define-minor-mode'
Loading /home/apollo/.emacs.d/elpa/mathpix.el.git/mathpix.el (source)...done

File the issue there, as the software is proprietary by default, even
it is not possible to make proprietary Emacs extensions, so the
software has to be first licensed by GPL3+ or compatible license. 

Otherwise I cannot test it until that issue is solved as I don't want
to deal with proprietary software.
