Is there a way to change file's target membership in Xcode project via command line?
Here's what I'm trying to do via Xcode's UI:
I also had to do this for CI. After lots of digging, I do not believe this is common enough for anyone to have written a tool to help with doing.
The only conclusion I came to was to edit the project.pbxproj file directly, which is never a great thing to do. None of the tools which claim to do this were of any help until I found this stackoverflow answer on editing the project.pbxproj file. Essentially, you can convert the project.pbxproj file into a JSON format using plutil -convert json project.pbxproj and use a JSON manipulation tool to make those files as headers then point them to be headers of whichever target you would like.
When converting the project.pbxproj into JSON format, be aware that Xcode will no longer be able to show you the project navigator for that project. It will still build and run, however, so this is really only useful if you're planning to do this right before building (such as for CI).
(EDIT: As of July 2022, Xcode will now properly read a JSON version of its .pbxproj to allow you to view your files in the project navigator. I'm not sure which version introduced this, but it is at least now possible with later versions of Xcode.)
The format project.pbxproj as JSON has nearly all the important data under the "objects" key. The file you want to be a header already has an entry with the key being the UUID for the file and a path value you can use to relate the UUID to your file. Here's an example of that format:
// UUID for your file
"65TYSSDXHSLP4UUOAD9D40C322AAGHM9": {
"path": "MyHeader.h", // Your file's name
"isa": "PBXFileReference",
"includeInIndex": "1",
"lastKnownFileType": "sourcecode.c.h",
"sourceTree": "<group>"
}
There's another entry to declare this file as a header, which has its own UUID and a reference to the UUID of your file:
// UUID for your file as a header
"YU3BSD39O9PT5RESDFV741D1": {
"isa": "PBXBuildFile",
"fileRef": "65TYSSDXHSLP4UUOAD9D40C322AAGHM9", // UUID for your file MyHeader.h
"settings": {
"ATTRIBUTES": [
"Public" // could also be Project or Private
]
}
}
Then finally, your target has a list of header files where you will want the UUID for the header reference to go.
"A82GAE9A5HUIO063IOPQAAQIUFGSNXZ": {
"isa": "PBXHeadersBuildPhase",
"buildActionMask": "2147483647",
"files": [
"YU3BSD39O9PT5RESDFV741D1" // UUID for your file as a header
],
"runOnlyForDeploymentPostprocessing": "0"
}
Again, changing the project.pbxproj file directly is never a great idea, but until there's a better tool for making these changes without using Xcode, it's the best I could find. If anyone else is aware of something I'm not, please let me know.
I have class in a file name MyClass.swift
class MyClass {
var arrayOfString : [String] = []
}
I need my team to append strings in this array when needed without modifying in the same file (before runtime) so if there is any way to do this use extension and modify in this array class for example to make a new file called NewClass.swift?
extension MyClass {
arrayOfString = ["New Value"]
}
Add a function to the extension class and ask your team to add the data there.
extension MyClass {
func addDataHere() {
arrayOfString = ["New Value"]
//ASK THEM TO ADD DATA
arrayOfString.append("ONE")
arrayOfString.append("TWO")
}
}
Try this, if you are looking for the same.
If I understand correctly you wish to have different array initialisers in different files which are combined at compile time into a single initialiser, that is using your example convert:
class MyClass {
var arrayOfString : [String] = []
}
and:
extension MyClass {
arrayOfString = ["New Value"]
}
into:
class MyClass {
var arrayOfString : [String] = ["New Value"]
}
and:
extension MyClass {
// arrayOfString = ["New Value"]
}
or something equivalent to that.
I do not believe the Swift language supports that. However Xcode is can help you here, it has two facilities you can use to construct a solution:
Build Phases - Run Script
In your Project's Settings there is an entry "Build Phases" which defines the set of operations Xcode goes through in building your project. The default set is: Target Dependencies, Compile Sources, Link Binary With Libraries and Copy Bundle Resources. The list is processed in order, top to bottom.
You may add other phases including a "Run Script" one which runs a script you write, which could be a shell script, Python code, Ruby code, etc. etc. The phase can optional take specified input files and produce output files.
Xcode provides a temporary build products directory into which you can write output files, any output files are subject to further processing by Xcode.
Build Rules
Also in your Project's Settings there is an entry "Build Rules" which defines how Xcode handles different file types. This allows you to introduce new file extensions which you then process to produce a new file with a known extension in the temporary products directory which Xcode will then further process. For example, you could write files with a .ourSwift extension which a processed by a script you provide into .swift files.
What could you do with these?
Well you could write a script which scans the project's source files, extracts the distributed parts of the initialiser, combines them and writes them into an existing or new file. The design of this and what you implement it in is totally up to you. For example, if you have your team indicate what they need to add to the initialiser by a special comment you might be able to use a simple combination of grep and sed to achieve your goal. Apple used to publish a more involved example of processing .strings files using a Ruby script which you might still be able to find in the dusty corners of the internet.
Xcode's documentation for these features won't win any prizes but that is your primary source; go read, explore, trial and you'll probably quickly have a solution that meets your needs.

I am trying to open some website url links with a parameter in my browser. I made a batch file using this code :
#echo off
start "images" "www.images.com/1000/image.jpg"
start "images" "www.images.com/1001/image.jpg"
start "images" "www.images.com/1002/image.jpg"
...
...
start "images" "www.images.com/5000/image.jpg"
All I want is to create a For loop that will do that :
For (i=1000; i<5000 ; i++)
{
start "images" "www.images.com/i/image.jpg"
}
where "i" is a parameter of the website link. I am new in the batch file creation and I cannot figure out how to make it work. I tried this one but it did not work:
for i in {1000..5000}
do
start "images" "www.images.com/$i/image.jpg"
This question is a first step. Then i want to save the images shown on this links, only if the links are valid (not dead like in 403, 404 errors)
For /L %%i in (1000,1,5000) do (
start "images" "www.images.com/%%i/image.jpg"
)
You didn't even try using correct syntax, instead assuming that cmd is like bash. Yay.
What you're looking for can be found with help for:
for /l %%i in (1000,1,5000) do ...
I'm unsure how you even plan to proceed from here, though, as your current approach will not allow you to save images. Also opening 4000 tabs in your browser will likely be not fun either.
You may want to take a look at PowerShell where the whole task you described is trivial:
4000..5000 | % { [IO.File]::WriteAllBytes("H:\$_.png", (iwr www.images.com/$_/image.jpg).Content) }
And even without the need for external programs (e.g. wget or curl).
Is it possible to add custom code snippets in Visual Studio Code? And if so, how? VSCode is based on Atom, so it should be possible.
Hit > shift + command + p and type snippets
Select Preferences: Configure User Snippets
Choose the language type for which you want to add the custom snippet in the vscode inputbox
vscode has comments to explain on how to add a snippet, as described on :> vsdoc or you can follow the next link with a short guide:
Lets say, we want to open custom snippets for the language GO. Then we can do:
Hit > command + p
Type: go.json + enter And you land on the custom snippet page
Snippets are defined in a JSON format and stored in a per-user (languageId).json file. For example, Markdown snippets go in a markdown.json file.
Using tools:
Snippet Generator extension (recommended)
Online snippet generator
Option 1 - Use the Snippet Generator extension.
It supports code to JSON conversion with optional scope support and space to \t conversion.
Demo:
Option 2 - Another extension is snippet-creator (deprecated).
After installing it, all you have to do is to :
Select the code that you want to make a snippet.
Right-click on it and select "Command Palette"(or Ctrl+Shift+P).
Write "Create Snippet".
Choose the type of files needed to be watched to trigger your snippet shortcut.
Choose a snippet shortcut.
Choose a snippet name.
Option 3 - check this website. you can generate snippets for vs code, sublime text, and atom.
Once snippet being generated on this site. Go to the respective IDE's snippet file and paste the same. For example for a JS snippet in VS code go to File->preference->user snippet then it opens javascript.json file then paste the snippet code from an above site inside this and we are good to go.
As of version 0.10.6 you can add custom snippets. Read the documentation on Creating your Own Snippets.
You can find/create custom snippets by placing the json file in C:\Users\<yourUserName>\AppData\Roaming\Code\User\snippets.
For example, a custom javascript snippets would be in a \snippets\javascript.json
You can also publish you snippets which is a really neat feature as well. John Papa created a nice angular + typescript snippet you can download as an extension in the marketplace.
Here is an example snippet taken for the documentation on a javascript for loop:
"For Loop": {
"prefix": "for",
"body": [
"for (var ${index} = 0; ${index} < ${array}.length; ${index}++) {",
"\tvar ${element} = ${array}[${index}];",
"\t$0",
"}"
],
"description": "For Loop"
},
Where
For Loop is the snippet name
prefix defines a prefix used in the IntelliSense drop down. In this case for.
body is the snippet content.
Possible variables are:
$1, $2 for tab stops
${id} and ${id:label} and ${1:label} for variables
Variables with the same id are connected.
description is the description used in the
IntelliSense drop down
You can check out this video for a quick short tutorial

Go to File --> Preferences --> User Snippets. Select your preferred language.
Now type the following code to make a for loop snippet:
"Create for loop":{
"prefix": "for",
"body":[
"for(int i = 0; i < 10; i++)",
"{",
" //code goes here",
"}"
],
"description": "Creates a for loop"
}
You are done.
Type "for" in the editor and use the first prediction.
SHORTCUT
install snippet-creator extension (now deprecated).
Highlight the code that you need to make snippet.
press ctrl+shift+P and type "Create snippet" on the command palette and
press ENTER.
select language for which you want to create snippet(eg:-CPP), then type
snippet name, type snippet shortcut and then type snippet description.
You are now good to go.
Type the snippet shortcut in the editor that you entered in step 4, and select the prediction (if no prediction comes press ctrl+space) that comes first.
Hope this helps :)
Note: goto File->Preferences->User Snippets. Then select the language in which youcreated the snippet. You will find the snippet there.
You can add custom scripts, go to File --> Preferences --> User Snippets. Select your preferred language.
If you choose Javascript you can see default custom script for console.log(' '); like this:
"Print to console": {
"prefix": "log",
"body": [
"console.log('$1');",
"$2"
],
"description": "Log output to console"
},
There's a VSCode Plugin called: snippet-creator (now deprecated).
After installing it , all you have to do is to:
Select the code that you want to make it a snippet.
Right click on it and select "Command Palette"(or Ctrl+Shift+P).
Write "Create Snippet".
Choose type of files needed to be watched to trigger your snippet shortcut.
Choose a snippet shortcut.
Choose a snippet name.
That's All.
Note : if you want to edit your snippets , you will find them in [fileType].json
Example : Ctrl+P , then select "javascript.json"
I tried by adding snippets in javascriptreact.json but it didn't worked for me.
I tried adding snippets into global scope, and it's working like charm.
FILE --> Preferences --> User snippets
here select New Global Snippets File, give name javascriptreact.code-snippets.
For other languages you can name like [your_longuage].code-snippets
This is an undocumented feature as of now but is coming soon. There is a folder you can add them to and they will appear, but it may change (its undocumented for a reason).
Best advice is to add this to the uservoice site and wait til its final. But it is coming.
On MacOS:
Open the VSCode
Code -> Preferences -> User Snippets
Search for "python" (or any language)
Write your snippet like this:
{
"Write pdb": {
"prefix": "pdb",
"body": [
"import pdb; pdb.set_trace()",
"$2"
],
"description": "Write pdb.set_trace() to debug Python scripts"
}
}
Save the file with command + S.
VSCode introduce this in version 0.5, see here.
Snippet syntax follows the TextMate snippet syntax and can write in User Preferences.
If you'd rather not deal with writing your snippets in JSON, check out Snipster. It lets you write snippets as you would write the code itself - not having to wrap each line in quotes, escape characters, add meta information, etc.
It also lets you write once, publish anywhere. So you can use your snippet in VS Code, Atom, and Sublime, plus more editors in the future.
This may not be a real answer (as some have answered above), but if you're interested in creating custom code snippets for other people, you can create extensions using yeoman and npm (which by default comes along with NodeJS) . NOTE: This is only for creating snippets for other's systems. But it also works for you too! Except you need JS code for whole thing.
You can add custom scripts, go to File --> Preferences --> User Snippets. Select your preferred language.
Like mine code is go, I do it as below:
"channel code": {
"prefix": "make_",
"body": [
"${1:variable} := make(chan ${2:type}, ${3:channel_length})",
"$4"
]
}
explanation: $1 will take your tabs & to give hints what are those tabs values, we make it like ${1:some_variable} which could give us hints what are those
I hope, it helps!
I have a simple dart class I am trying to test.
To test it I need to open a txt file, feed the content to an instance of the class and check that the output is correct.
Where do I place this txt file? The txt file is useless outside of testing.
Also, related, how do I acess its directory consistently? I tried placing it in the test folder, but the problem is that:
System.currentDirectory
Returns a different directory if I am running the test on its own or the script calling all the other test dart files on at a time
I check if System.currentDirectory is the directory containing the pubspec.yaml file, if not I move the current directory upwards until I found the directory containing the pubpsec.yaml file and then continue with the test code.
Looks like package https://pub.dev/packages/resource is also suitable for this now.
I have still not found a definitive answer to this question. I've been looking for something similar to the testdata directory in Go and the src/test/resources directory in Java.
I'm using Android studio and have settled on using a test_data.dart file at the top of my test directory. In there I define my test data (mostly JSON) and then import it into my individual tests. This doesn't help if you need to deal with binary files but it has been useful for my JSON data. I'll also inject the JSON language with //language=json so I can open the fragment in a separate window to format.
//language=json
const consolidatedWeatherJson = '''{
"consolidated_weather": [
{
"id": 4907479830888448,
"weather_state_name": "Showers",
"weather_state_abbr": "s",
"wind_direction_compass": "SW",
"created": "2020-10-26T00:20:01.840132Z",
"applicable_date": "2020-10-26",
"min_temp": 7.9399999999999995,
"max_temp": 13.239999999999998,
"the_temp": 12.825,
"wind_speed": 7.876886316914553,
"wind_direction": 246.17046093256732,
"air_pressure": 997.0,
"humidity": 73,
"visibility": 11.037727173307882,
"predictability": 73
}
]
}
''';
Using the Alt + Enter key combination will bring up the Edit JSON Fragment option. Selecting that open the fragment in a new editor and any changes made there (formatting for example) will be updated in the fragment.
Not perfect but it solves my issues.
