tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.
Readme
Flametree is a Python library which provides a simple syntax for handling files and folders
(no os.path.join
, os.listdir
etc.), and works the same way for different file systems.
Write a Flametree program to read/write files in disk folders, and your code will also be able to read/write in zip archives and virtual (in-memory) archives - which is particularly useful on web servers.
As an illustration, here is how to use Flametree to read a file texts/poems/the_raven.txt
, replace all
occurences of the word "raven" by "seagull" in the text, and write the result to a new
file the_seagull.txt
in the same folder:
.. code:: python
from flametree import file_tree
with file_tree("texts") as root:
poem_text = root.poems.the_raven_txt.read()
new_text = poem_text.replace("raven", "seagull")
root.poems._file("the_seagull.txt").write(new_text)
Even in this very simple use case, the syntax is clearer than the os
way,
which would write as follows:
.. code:: python
import os
with open(os.path.join("poems", "the_raven.txt"), "r") as f:
poem_text = f.read()
new_text = poem_text.replace("raven", "seagull")
with open(os.path.join("poems", "the_seagull.txt"), "w") as f:
content = f.write(new_text)
Moreover, the same Flametree code also works for files inside a zip archive:
.. code:: python
with file_tree("my_archive.zip") as root:
poem_text = root.poems.the_raven_txt.read()
new_text = poem_text.replace("raven", "seagull")
root.poems._file("the_seagull.txt").write(new_text)
Now in hard mode: suppose that your server receives binary zip data of an
archive containing poems/the_raven.txt
, and must return back a new zip
containing a file poems/the_seagull.txt
. Here again, the syntax of the core
operations is the same:
.. code:: python
destination_zip = file_tree("@memory") # Create a new virtual zip
with file_tree(the_raven_zip_data) as root:
poem_text = root.poems.the_raven_txt.read()
new_text = poem_text.replace("raven", "seagull")
destination_zip._dir("poems")._file("the_seagull.txt").write(new_text)
destination_zip_data = destination_zip._close()
# Now send the data to the client
See section Usage below for more examples and features.
PIP installation:
.. code:: bash
pip install flametree
