Emacs
How can I compile Emacs from scratch? ⚓︎
git clone -b emacs-27 git://git.sv.gnu.org/emacs.git
cd emacs
sudo apt-get build-dep emacs
./autogen.sh
./configure --with-x-toolkit=lucid --with-mailutils
make -j4
./src/emacs // test that its working
sudo make install
Why do some functions have double dashes? ⚓︎
As an example of what I mean, org-roam
had seemingly the same function names at one point, despite the only difference being some double dashes
Here is an example of what I mean
At first glance, the naming differences between org-roam-capture--get-point
and org-roam--capture-get-point
seems completely arbitrary
Supposedly, since there is no such thing as internal vs external functions, it’s a convention for declaring that a function should be considered private or internal only
I still don’t understand the above example since they both have double hyphens
Why do some lists start with a backtick (`
) instead of a comma ('
) ⚓︎
Lists that start with a `
end up having values interpolated.
Compare the following two examples:
'(,(concat "Hello, " "World"), "Nice to meet you?")
; (,(concat "Hello, " "World")
; ,"Nice to meet you?")
As you can see, we got the exact same list that we defined when starting with a '
How about using a `
?
`(,(concat "Hello, " "World"), "Nice to meet you?")
; ("Hello, World" "Nice to meet you?")
The concat
expression is evaluated and we get back two strings!
How can I find out what places Emacs is checking for my passwords? ⚓︎
