Hey everyone :) I just found Textualize/textual#24 and was wondering if it's status has changed since July of last year.. If so, what would be the best approach for an interactive Table widget. Are contributions for such a thing welcome/encouraged or should I hold out for 0.2 (css) to be released first?
Hi everyone. We have new Discourse community for all things Textual https://community.textualize.io/
Sorry I haven't been responsive here, but we're working really hard on this new CSS version, which will make things much easier for you.
I'm thinking of closing the gitter.im channel unless you really like the chat format over a forum.
out of curiosity, what does a discourse forum brings that is not possible with github discussions? centralization of discussions instead of scaterring them in multiple repos? ownership of the data (self-hosting?)?
unable to print = gc.garbage blocks
@graingert do u have any idea? /\

Can you link me to the pprint source?
You can dig it out of sys._current_frames()
import asyncio
import gc
from gc import get_objects
from pprint import pprint
from starlette.applications import Starlette
from starlette.responses import JSONResponse, Response
from starlette.routing import Route
from starlette.requests import Request
gc.set_debug(gc.DEBUG_LEAK)
async def homepage(request: Request):
request.state.test = [x for x in range(999999)]
return JSONResponse({'hello': 'world'})
async def collect(request: Request):
n = gc.collect()
pprint(gc.garbage)
return JSONResponse({"collected": n})
app = Starlette(routes=[Route('/', homepage), Route('/collect', collect)])
I spent the whole day debugging this
encode/uvicorn#1564 << I think there's a reference cycle on ServerState <-> HTTP Protocol
what I'm saying it's unrelated to rich
it's just to give you context...
While debugging the uvicorn issue, I tried to use
from rich.pretty import pprint but the pprint(gc.garbage) blocks me 4ever
It's got a thing for finding out what's keeping something alive
So you'd do something like
class Canary: pass
o = Canary()
request.state.foo = o
del o
...
objgraph.show_chain(
objgraph.find_backref_chain(
random.choice(objgraph.by_type('Canary')),
objgraph.is_proper_module),
filename='chain.png')```
what do I get from this? :laughing:
this is just to give me the confirmation, right? because I think I've spotted the reference cycle in the code already
The issue you have is there's a reference cycle that the GC resolves, but you don't want to wait for that?
I don't fully understand the question, and I don't want to give an answer that may mislead us here. So to enrich my knowledge here...
What does it mean that the "GC resolves, but I don't want to wait for that"? On my situation, if I manually run

gc.collect(), my memory goes back to what I'd expect it be - does this say something?

I mean if it's just a cycle then the GC should clean it up for you
You need to find out what's keeping a reference after the request is finished?
sorry if this is an annoying FAQ but is there some rough ETA for a beta-release of the CSS branch? I checked many TUI frameworks and Textual seems to be the best design by far.
I really love it, except the fact that it's horribly documented and not quite ready, yet :)
I looked for some "app.reset()" or "app.console.reset()" function to get the terminal in a normal state. Didn't find anything. Where does textual/rich reset the terminal upon exit?
