PUG ( web template engine ) for Python ๐Ÿ (programming.dev)
submitted 1 week ago* (last edited 5 days ago) by Rick_C137@programming.dev to c/python@programming.dev

Hi,

I've discover haml and pug [^1] ( both web template engine )

It's totally Pytonic ! ( and make even more sense to use it with python rather than JS ๐Ÿคฎ )

I've look, if it exist for Python, but so far, I've found only

The first, only convert pug into another template :/
The second, didn't pass the alpha version.
The third, require dependence, not maintained etc.. \

So I didn't found a Python package that could do haml/pug to html directly, without too much dependence...

For example:

From

html
  head title Example for Python discuss
  body
    h1 Hello world
    p This is a paragraph.

To

<html>
  <head>
    <title>Example for Python discuss</title>
  </head>
  <body>
    <h1>Hello world</h1>
    <p>This is a paragraph.</p>
  </body>
</html>

Do you know if such thing exist ?
If not, I will build my own (FLOSS). ( I'm open to any advice to do so :) )

Thanks

[^1]:Pug is a template engine heavily influenced by Haml and implemented with JavaScript ๐Ÿคฎ for Node.js

Hi,

I'm following my previous post

[โ€“] Rick_C137@programming.dev 1 points 1 month ago (1 children)

I finally manage to encrypt the body trough ptyhon-gnupg ( warning their documentation is still in alpha stage. )

now, remain to encrypt the subject (ThunderBird compatible) if you have any clues I'm all ears

When time permit I will publish my code in a pastbin.

instead of using a library I can directly use subprocess with gnupg but in both case it seem gnupg require to import the public key to the keyring !? I don't want that.

Hi,

I'm already using

from smtplib import SMTP_SSL
from email.message import EmailMessage

To send emails.

Now I would like to be able to encrypt them with the public key of the recipient. ( PublicKey.asc )

an A.I provide me this

import smtplib
from email.message import EmailMessage
from cryptography.hazmat.primitives.asymmetric import ec
from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.ciphers.aead import AESGCM

# Load the ECC public key from the .asc file
with open('recipient_public_key.asc', 'rb') as key_file:
    public_key_bytes = key_file.read()
public_key = ec.EllipticCurvePublicKey.from_public_bytes(
    ec.SECP384R1(),
    public_key_bytes
)

# Create the email message
msg = EmailMessage()
msg.set_content('This is the encrypted email.')
msg['Subject'] = 'Encrypted Email'
msg['From'] = 'you@example.com'
msg['To'] = 'recipient@example.com'

# Encrypt the email message using the ECC public key
nonce = bytes.fromhex('000102030405060708090a0b0c0d0e0f')
cipher = AESGCM(public_key.public_key().secret_key_bytes)
ciphertext = cipher.encrypt(nonce, msg.as_bytes(), None)

# Send the encrypted email
server = smtplib.SMTP('smtp.example.com')
server.send_message(msg, from_addr='you@example.com', to_addr='recipient@example.com')
server.quit()

# Save the encrypted email to a file
with open('encrypted_email.bin', 'wb') as f:
    f.write(ciphertext)

I like the approach, only one "low level" import cryptography

but the code seem wrong. if the body has been encrypted as ciphertext I don't see this one included while sending the email.

How are you doing it ? or do you have good tutorial, documentations ? because I found nothing "pure and simple" meaning not with of unnecessary stuff.

Thanks.

How store a file with a timestamp in a decentralized manner? (programming.dev)

Hi,

I'm looking for a solution to archive files in a decentralized system. that would meet those requirement:

  • FLOSS
  • date-stamp the upload of the file.
  • immutable storage ~ WORM
  • anonymous (like TOR)

I was considering IPFS but it does not date-stamp the upload :'( you can make a description-file but this is unreliable, as you can set any date..

I'm lost between hyphanet.org and Freenet.org ?!
are those the same project ?

According to A.I:

Hyphanet is focused on secure, private, and efficient communication and data sharing, with an emphasis on enabling users to monetize their data while maintaining control over their data sovereignty.

is that true ? I can't found the information on their website...

`chown` on a sdcard directory impossible... in c/android@lemmy.world
[โ€“] Rick_C137@programming.dev 1 points 1 month ago* (last edited 1 month ago)

Thanks all for your input !

So yes /sdcard was /storage/emulated/0 and it's a real sd-card.

That was indeed formatted as FAT, I reformatted into EXT4 (from a desktop Linux) put the SD-card back into the phone and started the phone.

Ive tried (in the phone)

su
chmod 777 /storage/emulated/0 #yes it's still mounted as emulated !
stat /storage/emulated/0
#...
#Access: (0771)
#....

So I'm still blocked... any ideas ?

Thanks.

chown on a sdcard directory impossible... (programming.dev)
 

Hi,

I would like to change the owner of a directory on the sdcard /sdcard/aDirectory

I have a terminal installed on my Android 10 (LineageOS 17) com.android.terminal

sudo is not present so I use su and it works.

su
#Terminal was granted Superuser rights

cd /sdcard
chown 10:10 aDirectory
#I don't get any error message.

stat aDirectory
#Uid (0/root)

So the owner stay root no matter what I'm doing, any ideas ?

[โ€“] Rick_C137@programming.dev 1 points 2 months ago* (last edited 2 months ago) (1 children)

Thank you all for your input.. but it seem my question is still not fully answered...

let me rephrase, I'm not looking to have a GUI to transfer files, but I would like to execute terminal command remotely (from my computer) to my android phone. Like SSH .

So I've read that I can install a SSH server on my android phone.. (If you know some's (FLOSS), I'm all ears) Or if you know a better way than SSH I'm all ears too.

Thanks.

How terminal in, on Android (programming.dev)
 

Hi,

I created another user on my custom rom Android (aka Multiple users)

Unfortunately when doing so the system do not adapt the permission of the sdcard and some other directory, thus the new user can't access them :/

So I wanted to "remote" terminal into my android device from my computer.

How are you achieving this ? ( without 3thparty apps please ! )

Thanks.

Hi everyone,

Is there somewhere a list of all the changes made compared to Firefox ?

edit:

~~Sorry if it's been already asked over here, but it seem that Lemmy do not provide a search within a Community ๐Ÿ˜ฎ~~

no, actually we can, there isn't a shortcut to make such a search. and no ability to limit the search to the titles..

Nginx how enable CORS for multi origins ? (programming.dev)
 

cross-posted from: https://programming.dev/post/18360806

Hi everyone,

I would like to enable Cross-Origin Resource Sharing on my Nginx server. for few origins (cors requestor)/domains.

I've found this article https://www.juannicolas.eu/how-to-set-up-nginx-cors-multiple-origins that is nice, but not complete and on my browser seem really hard to read due to the layout ๐Ÿคฎ

So I've opened a CodeBerg git repository for the good soul that want to perfect this piece of code the allow the most of use to use CORS with Nginx.

https://codeberg.org/R1ckSanchez_C137/BestOfxxx/src/branch/main/Nginx/CORS_MultiDomains.py

If you don't want to create an account on codeberg feel free to post your code here !

server {
    # Server

    map "$http_origin" $cors { # map in Nginx is somewhat like a switch case in a programming language.
        default ''; #Seem to set $cors to '' empty string if none of the follwing rexeg match ?
        "~^https:\/\/([\w-_\.]+\.)?example.com$" "$http_origin";
            #regex domain match
            # ~ mean I suppose the string is RegEx ?
            # Need to come with a RegEx expression that match https://anything.example.com[optional ports and Query string ?X=Y]
        "~^https:\/\/([\w-_\.]+\.)?example2.com$" "$http_origin"; #regex domain match
        }
               

    location /static {
        
        # if preflight request, we will cache it
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Max-Age' 1728000; #20 days
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204; #https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/204 }

        if ($cors != "") {
            add_header 'Access-Control-Allow-Origin' "$cors" always; # <-- Variable $cors
            add_header 'Access-Control-Allow-Credentials' 'true' always;
            add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
            add_header 'Access-Control-Allow-Headers' 'Accept, Authorization, Cache-Control, Content-Type, DNT, If-Modified-Since, Keep-Alive, Origin, User-Agent, X-Requested-With' always;}

       # configuration lines...

    }

Hi,

I got FileA that have 640 a getfacl FileA give me

# file: FileA
# owner: me
# group: me
user::rw-
user:aUser:r--
group::r-x			#effective:r--
mask::r--
other::---

So it's give me the expected...

but when I do

chmod 600 aFile
getfacl aFile

...
user:aUser:r--		#effective:---
...
mask::---
...

Why suddenly aUser lost his ability to read the file !?!?!

Update, this is only happening when I copy files from a ~SMB share... :'(
Otherwise it's correct...

FACL, Get effective: --- (programming.dev)
 

Hi,

I've set for a directory the following

setfacl -dm u:aUser:r aDirectory
#set new files to be readable by aUser

cp ~/Desktop/aFile.txt /xx/xx/xx/aDirectory

getfacl aFile.txt #the copied one

# file: aFile.txt
# owner: me
# group: me
user::rwx
user:aUser:r--
group::r-x
mask::rwx
other::rwx

So indeed we see the aUser got r--

but

stat aFile.txt

return

(0777/-rwxrwxrwx) #!!!!

is that normal !!!!???

Thanks.

What vm software you use on linux in c/linux@lemmy.ml
Recursive execute(x) required to enable nginx to read a directory !?? [ SOLVED ] in c/linux@lemmy.ml
[โ€“] Rick_C137@programming.dev 1 points 3 months ago

Thank you all !

Indeed setting execute perm on example, sub1, sub2, static

The program/user have now access to the directory.

In order words all the parents directory need at least execute in order to have access in the targeted directory...

Now I gave 751 for static. Meaning than others (here nginx) cannot list the files within. But never the less it works
the static files are appearing when requested (HTTP) but forbidding nginx to list the directory is changing something ? (performance/security)

Thanks
