Duplicate iPhone Simulators Appeared on My Xcode - xcode

A duplicate iPhone simulator just appeared after I deleted ~/Library/Developer/Xcode/CoreSimulator folder
How to solve this problem?
I've tried to delete ~/Library/Developer/Xcode folder and ~/Library/Application Support/iPhoneSimulator folder. But all failed.

It may happen because of multiple Xcode installed or during Xcode upgrades. The only thing that need to be done is to open Xcode -> Window -> Devices select duplicated device and delete it.

I have a same issue after installing Xcode beta version.
I found that there are several solution to fix this issue.
1. snapshot
https://github.com/fastlane/fastlane/tree/master/snapshot
usage : gem install fastlane; fastlane snapshot reset_simulators
I solved my problem with this library and it is very simple to use.
2. Xcode->Window->Devices
You can check installed simulators and delete them. But it will take too long time if you have many simulators.
3. xcrun simctl delete
you can use xcrun command in terminal. But you need to input a specific device name with command.

I had kinda a lot! Too many to delete one by one in Devices, thanks Apple for not including multi-select. Don't double tap delete either or you'll crash Xcode. I found a script that could delete duplicates however it only worked if there was only 1 duplicate of each type so didn't work in my case. I therefor edited the script to simply delete all the simulators, and then you can add any you need just by clicking plus in the Devices window.
Save the following as remove_all_sims.py:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import re
from subprocess import Popen, PIPE
from subprocess import call
p = Popen(["xcrun","simctl","list","devices"], stdin=PIPE, stdout=PIPE, stderr=PIPE)
output, err = p.communicate(b"input data that is passed to subprocess' stdin")
blocks = re.split("--\s+(.*?)\s+--",output)
dic = {}
i=0
for block in blocks:
matches = re.findall("iOS 8.4",block)
if len(matches)>0:
content = blocks[i+1]
lines = content.split("\n")
for line in lines:
line = line.strip()
if len(line)>0:
match = re.match("(.*?)\(",line)
if match:
devicename = match.group(1)
idMatch = re.match(".*?\((.*?)\).*",line)
dic[devicename] = idMatch.group(1)
call(["xcrun","simctl","delete",idMatch.group(1)])
# print match.group(1)
# print line
i = i+1
for guid in dic.itervalues():
call(["xcrun","simctl","delete",guid])
Then run:
python remove_all_sims.py
Note its hard coded for iOS 8.4 simulators only.

How to get progress bar with tqdm in a for loop over directory

I am trying to conditionally load some files from a directory. I would like to have a progress bar from tqdm on the process. I currently running this:
loaddir = r'D:\Folder'
# loop the files in the directory
print('Data load initiated')
for subdir, dirs, files in os.walk(loaddir_res):
for name in tqdm(files):
if name.startswith('Test'):
#do things
which gives
Data load initiated
0%| | 0/6723 [00:00<?, ?it/s]
0%| | 26/6723 [00:00<00:28, 238.51it/s]
1%| | 47/6723 [00:00<00:31, 213.62it/s]
1%| | 72/6723 [00:00<00:30, 220.84it/s]
1%|▏ | 91/6723 [00:00<00:31, 213.59it/s]
2%|▏ | 115/6723 [00:00<00:30, 213.73it/s]
This has two problems:
When progress is updated a new line appears in my IPython console in Spyder
I am actually timing the loop over the files and not over the files that start with 'Test' and therefore progress and remaining time are not accurate.
However, if I try this:
loaddir = r'D:\Folder'
# loop the files in the directory
print('Data load initiated')
for subdir, dirs, files in os.walk(loaddir_res):
for name in files:
if tqdm(name.startswith('Test')):
#do things
I get the following error.
Traceback (most recent call last):
File "<ipython-input-80-b801165d4cdb>", line 21, in <module>
if tqdm(name.startswith('Probe')):
TypeError: 'NoneType' object cannot be interpreted as an integer
I would like to have a progress bar in only one line that updates whenever the startswith loop is activated.
----UPDATE----
I also found out here that it can also be used like this:
files = [f for f in tqdm(files) if f.startswith('Test')]
Which allows to track progress with list comprehension by wrapping the iterable with tqdm. However in spyder this results in a separate line for each progress update.
----UPDATE2----
It actually works fine in spyder. Sometimes if the loop fails, it might go back to printing one line of progress update. But i haven't seen this very often after the latest updates.
firstly the answer:
loaddir = r'D:\surfdrive\COMSOL files\Batch folder\Current batch simulation files'
# loop the files in the directory
print('Data load initiated')
for subdir, dirs, files in os.walk(loaddir_res):
files = [f for f in files if f.startswith('Test')]
for name in tqdm(files):
#do things
This will work in any decent environment (including a bare terminal). The solution is to not give tqdm the unused filenames. You may find https://github.com/tqdm/tqdm/wiki/How-to-make-a-great-Progress-Bar insightful.
Secondly the issue with multiple lines output is well-known and due to some environments being broken (https://github.com/tqdm/tqdm#faq-and-known-issues) by not supporting carriage return (\r).
The correct links for this problem in Spyder are https://github.com/tqdm/tqdm/issues/512 and https://github.com/spyder-ide/spyder/issues/6172
(Spyder maintainer here) This is a known limitation of TQDM progress bars in Spyder. I'd recommend you to open an issue about it in its Github repository.
Specify position=0 and leave=True like this:
for i in tqdm(range(10), position=0, leave=True):
# Some code
Or in a list comprehension:
nums = [i for i in tqdm(range(10), position=0, leave=True)]
It's worth to mention that you can set `position=0` and `leave=True` to be the default settings, so you won't need to specify them each time, like this:
from tqdm import tqdm
from functools import partial
tqdm = partial(tqdm, position=0, leave=True) # this line does the magic
# for loop
for i in tqdm(range(10)):
# Some code
# list comprehension
nums = [for i in tqdm(range(10))]

Use Bash's select from within Python

The idea of the following was to use Bash's select from Python, e.g. use Bash select to get the input from the user, communicate with the Bash script to get the user selections and use it afterwords in the Python code. Please tell me if it at least possible.
Have the following simple Bash script:
#!/bin/bash -x
function select_target {
target_list=("Target1" "Target2" "Target3")
PS3="Select Target: "
select target in "${target_list[#]}"; do
break
done
echo $target
}
select_target
it works standalone
Now I tried to call it from Python like this:
import tempfile
import subprocess
select_target_sh_func = """
#!/bin/bash
function select_target {
target_list=(%s)
PS3="Select Target: "
select target in "${target_list[#]}"; do
break
done
echo $target
}
select_target
"""
target_list = ["Target1", "Target2", "Target3"]
with tempfile.NamedTemporaryFile() as temp:
temp.write(select_target_sh_func % ' '.join(map(lambda s : '\"%s\"' % str(s),target_list)))
subprocess.call(['chmod', '0777', temp.name])
sh_proc = subprocess.Popen(["bash", temp.name], stdout=subprocess.PIPE)
(output, err) = sh_proc.communicate()
exit_code = sh_proc.wait()
print output
It does nothing. No output, no selection.
I'm using High Sierra MacOS, PyCharm and Python 2.7.
PS
After some reading and experimenting ended up with the following:
with tempfile.NamedTemporaryFile() as temp:
temp.write(select_target_sh_func % ' '.join(map(lambda s : '\"%s\"' % str(s),target_list)))
temp.flush()
# bash: /var/folders/jm/4j4mq_w52bx2l5qwg4gt44580000gn/T/tmp00laDV: Permission denied
subprocess.call(['chmod', '0500', temp.name])
sh_proc = subprocess.Popen(["bash", "-c", temp.name], stdout=subprocess.PIPE)
(output, err) = sh_proc.communicate()
exit_code = sh_proc.wait()
print output
It behaves as I expected it would, the user is able to select the 'target' by just typing the number. My mistake was that I forgot to flush.
PPS
The solution works for MacOS X High Sierra, sadly it does not for Debian Jessie complaining the following:
bash: /tmp/tmpdTv4hp: Text file busy
I believe it is because `with tempfile.NamedTemporaryFile' keeps the temp file open and this somehow prevents Bash from working with it. This renders the whole idea useless.
Python is sitting between your terminal or console and the (noninteractive!) Bash process you are starting. Furthermore, you are failing to direct the standard output pipe anywhere, so subprocess.communicate() actually cannot capture standard error (and if it could, you would not be able to see the script's menu).
Running an interactive process programmatically is a nontrivial scenario; you'll want to look at pexpect or just implement your own select command in Python - I suspect this is going to turn out to be the easiest solution (trivially so if you can find an existing library).

Updating the tab/file status after saving in a Sublime Text Plugin

This may be an old bug; I found this report. I'm using Sublime 3 but I think this code also works on 2.
When I call self.view.run_command('save') within a plugin, the save does happen -- I can type the file in a console window and see the results. The dirty flag seems to get cleared. But the tab for the file contains a dot rather than an x, indicating the file hasn't been saved. And sure enough, if you try to close it, it asks if you want to save the file.
Is there any way to refresh the file window so it recognizes that the file has been saved?
Here's my plugin code: (This is my first plugin so please excuse obvious style issues)
# Sublime Text plugin to insert output in the OUTPUT_SHOULD_BE comment
# Bind to key with:
# { "keys": ["f12"], "command": "insert_output" },
import sublime, sublime_plugin, pprint, os, re
class InsertOutputCommand(sublime_plugin.TextCommand):
def run(self, edit):
outfile = self.view.file_name().rsplit('.')[0] + ".out"
if not os.path.exists(outfile):
sublime.error_message("Not Found: " + outfile)
return
out_data = open(outfile).read().strip()
region = self.view.find(r"/\* OUTPUT_SHOULD_BE\n", 0)
if region:
self.view.insert(edit, region.end(), out_data)
self.view.run_command('save')
self.view.window().focus_view(self.view)
else:
sublime.error_message("Not Found: OUTPUT_SHOULD_BE")
I'm sure this is probably a terrible hack, but it works:
self.view.run_command("save")
# Refresh the buffer and clear the dirty flag:
sublime.set_timeout(lambda: self.view.run_command("revert"), 10)
The revert command, which must be delayed in order to work, simply brings back whatever is stored in the file. Since the file was successfully saved on disk, this is just the same file that we already see on the screen. In the process, the dirty flag is cleared and the dot on the file tab becomes an x.
Feels very hacky to me and I'd love a more proper solution. But at least it works, ugly or not.

Python: Check if a directory is an alias

Does python have a simple function for checking if a directory is an actual directory or if it's just an alias to another directory? I'm trying to list all files/folders in a directory but because of these alias folders, I'm getting a lost of stuff that looks like this:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle/Home/bundle
I know I can write a function that will compare paths and quit if it seems like I'm going in circles, but is there a simple function that does exactly that that I'm not aware of?
E.g.
os.isAlias( …pathname… )
Thanks!
Here's a version of os.path.realpath that works on Mac aliases as well as on symbolic links under Python 2:
from Carbon import File
def osx_realpath (path):
return File.FSResolveAliasFile(path, True)[0].as_pathname()
If you call osx_realpath on each directory before you recurse into it you should avoid duplication. Alternatively you could define something like
def is_osx_realpath (path):
return path == osx_realpath(path)
Here you have to worry a little about false negatives, however. If you filter for is_osx_realpath and the path you start with is an alias, your program will stop without looking at anything.
So far I don't know of a way to do this under Python 3. I have a question here where I'm hoping for an answer. Right now I can't do better than using subprocess.call to invoke something that does the check on the command line.
EDIT: I should add that not only is Carbon.File not available in Python 3, but it is deprecated and so is best avoided in Python 2 as well--however it's the most pragmatic solution I know of for Python 2 at present.
EDIT 2: here is a way to check if a file is an alias that I believe to be Python 3-friendly. However, I don't have code to resolve the alias. I believe you need PyObjC installed.
from AppKit import NSWorkspace
def is_alias (path):
uti, err = NSWorkspace.sharedWorkspace().typeOfFile_error_(
os.path.realpath(path), None)
if err:
raise Exception(unicode(err))
else:
return "com.apple.alias-file" == uti
(source)
The answer above is incorrect.
While it is true that Finder reports symlinks as alias, they are distinct things.
Symlinks are a basic feature of UNIX, but alias are a Apple only feature.
If you doubt this create a symlink to a directory and an alias. The symlink will be small typically 50-100 bytes, whereas the alias can be several MB.
os.path.islink( … ) will report symlinks, but not alias.
I am not sure how you would find them in Python, but the following link shows other methods.
https://stackoverflow.com/a/21151368/838253
You can check whether a file or directory is an alias with the GetFileInfo command in Mac OS X. GetFileInfo -aa foo prints a line with "1" if foo is an alias and "0" if not.
import subprocess
def is_alias(path):
return subprocess.check_output(["GetFileInfo", "-aa", path]) == "1\n"
Seems a little sad to spawn a process for every check, but I think this works with versions of Mac OS X since probably 10.4.4 (2006), 32-bit, 64-bit, Python 2 and Python 3. The version of GetFileInfo I have (from 2009) is a "universal" i386 + PPC binary.
GetFileInfo is part of Xcode, which is large, but you can download the command-line tools separately (see the "Separate Download" section here).
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/GetFileInfo.1.html
Old question, but I just ran into this myself.
I have no perfect method for checking if the file is an alias, however, if using mimetypes, python will return None for an alias or a symlink. Might be useful in some situations. I've only tested this in python 3.8 on macOS Big Sur.
import mimetypes
for idx, f in enumerate(filepaths):
type = mimetypes.guess_type(f)[0]
print(f"type is: {type}")
returns (without my added comments):
type is: None # <-- Folder Alias
type is: None # <-- File Alias
type is: text/x-python
type is: None # <-- Folder Alias
type is: video/mp4
type is: image/png
type is: None # <-- Folder Alias
type is: None # <-- Symlink
type is: image/png
type is: application/zip
type is: image/png
type is: image/jpeg
type is: None # <-- Symlink
I ran some files through exiftool just to see what types they returned, and aliases and symlinks both showed the following:
File Type : ALIAS
File Type Extension : alias
MIME Type : application/x-macos
You might be able to init the mimetypes for these, but haven't tested and not sure if it will give false positives if anything else shows up as application/x-macos

.Rprofile: How to set option "browser" correctly (to Chrome) so that help.start() works?

I work on Mac OS X 10.7.3 with R version 2.14.0 (2011-10-31). My ~/.Rprofile is
options(repos=c(CRAN="http://cran.ch.r-project.org",
BioC="http://www.bioconductor.org",
Omegahat="http://www.omegahat.org/R"),
pdfviewer=path.expand("~/R/misc/shell_scripts/skim"),
browser="mybrowser")
where mybrowser is a file in /bin/ which contains open -a "/Applications/Google Chrome.app". When I open R and type help.start(), all I obtain is that Chrome becomes active, but no real output from help.start(). How can I properly set up browser in options so that help.start() works as expected?
I originally just had browser="Chrome", but R couldn't find the browser. I tried several kinds of things to solve this (e.g., browser="/Applications/Google Chrome.app" [and various variants to escape the blank]), but none worked. I guess that's because sh /Applications/Google\ Chrome.app just does not work. On the Mac, applications are opened via open -a ..., that's why I created mybrowser. That finally opened the browser, but I couldn't figure out how to get help.start to work properly.
Create a Renviron file in your home (i.e ~/.Renviron) and add this line.
R_BROWSER=google-chrome
I'm not sure about "chrome" part, i use conkeror and my setup is :
R_BROWSER=conkeror
But this should do the tricks
In the meantime, Hans-Joerg Bibiko helped out: the solution is to set browser to browser="/usr/bin/open -a 'Google Chrome'"
If you look in utils:::print.help_files_with_topic (the function that actually issues the call to browseURL()), there is this really annoying line:
if (.Platform$GUI == "AQUA" && type == "html")
browser <- get("aqua.browser", envir = as.environment("tools:RGUI"))
And since .Platform$GUI == "AQUA" on OSX, this means that you have to do some trickery to browse help files in your favorite browser. Hence, in my .Rprofile (located here path.expand('~/.Rprofile'), of course), I included these lines.
options(help_type='html')
options(browser="/usr/bin/open -a '/applications/Google Chrome.app'")
p <- .Platform
p$GUI = 'unknown'
unlockBinding('.Platform', as.environment('package:base'))
assign('.Platform', p , envir=as.environment('package:base'))
lockBinding('.Platform', as.environment('package:base'))
rm(p)
So far it doesn't seem to have any effect other than enabling use of an alternate browser, but you may want to read the section labeled "Aqua" in ?.Profile if you're worried about messing around with base.
