Sounds & Fonts

Phuket2

This is an old post from Aug, 2013. But I was also looking to see if could programmatically get a list of the device fonts.
Does anyone know if any inroads have been made on this subject either by omz or a community member?

I looked at iosfonts.com, looks nice and up to date. Whilst the html code is script generated, sure there is still away to capture the rendered html and write a file to disk. But I realise this is not a nice way to get information without the website owners permission. I wouldn't do it that way, I am not looking for a solution just for myself, but all of the community here.

If there is no solution as yet, I think it would be nice if one of us spoke to the owners of this site or a similar site to get a supported interface for this community. If it's takes a donation to get it done, I am up for that.

BUT TO BE VERY CLEAR!!! I would never try and speak for the community here (pythonista) without express permission from omz. I am not trying to make a drama out of this issue. I just think some things are better solved for all of us at once rather than all of us going off in our own directions. I think this is a part of a platforms eveloution.

I don't always have the best ideas, but my heart is in the right place. Even though I have been out of the loop for many years, still many basic principles remain the same.

So if it has been solved great, love to hear the answer. Regardless, I wanted to bring up the point of trying to solve problems for all of us instead of individuals. Not to say that does not happen here. There is a huge amount of collaboration here. I really love it. The reasons for my comments. Anything that can be done to further pythonista and the community, I am in for.

It would be pretty easy to do this in 1.6, using objc_util, but I think you're still on 1.5, right?

Edit: It would look something like this:

from objc_util import *

UIFont = ObjCClass('UIFont')
all_fonts = []
families = UIFont.familyNames()
for family in families:
  names = UIFont.fontNamesForFamilyName_(family)
  all_fonts += names

Also- that website project is here:
https://github.com/mcritz/iosfonts?files=1

Read the license. Looks like you could use it with reference.
Json file in the data folder.

Yes omz , still 1.5. I can see I have to be a little bit careful about my comments as it seems a lot will be possible with 1.6 that's not possible in 1.5. I will roll my own solution for now. Good learning exp. for me. If I knew 1.5 back the front, I would be begging to get 1.6, but I have a long way to go :) but ok thanks, it answers my question.

omz

I don't really think you can copyright a list of fonts that is most likely generated automatically, but giving credit is always nice of course.

The benefit of generating the list dynamically on the device are

a) It would include custom fonts that are bundled with Pythonista.

b) It would update automatically when new fonts are added in the OS.

c) You don't need an internet connection.

...but anyway, right now it's only possible in the 1.6 beta, so if you're on 1.5, scraping iosfonts.com is probably a good option.

@omz, I agree with all your points. I think I am getting a little used to its not possible on iOS. But, I don't get stressed about it, I have time. I was very inflexible when I was younger, but now I am fairly laid back. Well really laid back :)

Actually, the repo that @cook points to, has a JSON file from the author of the iosfonts.com website. So that was nice of him. I have no commercial interest in any data, trying to write a few apps for some good friends.

@cook, thanks for the repo link. I have got the JSON file. Now will try to understand it programmatically :)

I'm pretty sure with the beta (which you can through via TestFlight by Apple https://appsto.re/us/W4wM1.i)
You are able to record audio. I remember a while back I asked a similar question, if you search "Audio" and look for a question by Reefboy1, there should be some help there. Good luck!

One way to get a list of fonts might be to pull a long list of font names off somewhere and see which ones don't produce errors if you try to use them.

Something like:

# coding: utf-8
from PIL import ImageFont

fonts = ["Helvetica", "Courier", "FontNameThatDoesNotExist", "Arial", "PoopingPenguins", "Inconsolata"]

installed_fonts = []
for font in fonts:
	try:
		ImageFont.truetype(font, 10)
		installed_fonts.append(font)
	except:
		print "Font '"+font+"' not found."


print "\nThe installed fonts are:\n" + "\n".join(installed_fonts)

omz

That won't work (console.set_font never throws an exception, it just ignores invalid fonts).

Webmaster4o

Ah, thanks. What about PIL.ImageFont?

omz

I think that would work, yes.

Webmaster4o

Edited, but still haven't tested. Can someone test that code for me?

ccc

Yes. The code works as expected if you remove the quotes around "font" in the append() line.

Of course it is also best practice to change except: to except TypeError:. ;-)

Webmaster4o

Right, @ccc, but I didn't know what kind of exception it would throw since I'm not somewhere I can test it.

@administrators @Omz,

I love that you can play sounds directly from their urls. Is there a way to simplify the script for this?

cvp

@jerovargas something like this?

import ui 
webview = ui.WebView()
webview.frame = (0,0,600,100)
url = 'https://s3-us-west-2.amazonaws.com/s.cdpn.io/123941/Yodel_Sound_Effect.mp3'
webview.load_url(url)
webview.present('sheet')

ccc

What about using these apis... http://omz-software.com/pythonista/docs/ios/sound.html

cvp

@ccc He asked to play directly from url...

mikael

@jerovargas, here’s a more light-weight alternative, which does play the sound ”directly from the url”, but only after it has been fully downloaded. I tried to combine streaming with play_effect, but was unsuccessful.

import tempfile
import sound
import requests

def play(url):
    with tempfile.NamedTemporaryFile(suffix='.caf') as fp:
        r = requests.get(url)
        r.raise_for_status()
        fp.write(r.content)
        sound.play_effect(fp.name)
        
play('https://s3-us-west-2.amazonaws.com/s.cdpn.io/123941/Yodel_Sound_Effect.mp3')

mikael

@jerovargas, ok, a version that streams a longer file instead of downloading it first.

import objc_util

objc_util.load_framework('AVFoundation')
AVPlayer = objc_util.ObjCClass('AVPlayer')

def play(url):
    audio_player = AVPlayer.playerWithURL_(objc_util.nsurl(url))
    audio_player.play()
    return audio_player

player = play('https://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_2MG.mp3')

input('Press enter to stop')

player.pause()
