VSCode - Implement Custom IntelliSense through Extension - visual-studio-code

I want to provide IntelliSense in VSCode based on a JSON file in the root folder of the project directory. The JSON file is at ./languages/english.json and is a key-value pair like below:
{
"sidebar.title": "Hello",
"sidebar.name": "John",
"sidebar.surname": "Doe",
"first.aaa": "Hello",
"first.bbb": "Hi",
}
I want VSCode to suggest this JSON's keys whenever I'm writing in a function named i18n().
Something like this:
I figured the best way to write a VSCode extension of my own. I've created one before, but how can I implement this feature?
P.S. I know about the option of using snippet json files directly, however those have the limitation of not being dynamically populated.

How can I manually edit the list of recently opened files in VS Code?

I rely heavily on the File: Open Recent… command to open frequently used files, but yesterday my local Google Drive folder got moved to a new location and now I can no longer access any of the files in that folder through the Open Recent panel because the paths don't match.
The fix would be as simple as replacing "/Google Drive/" with "/Google Drive/My Drive/" but I have no idea what file contains the list of files that appears in the recently opened panel.
I'm assuming it's somewhere in ~/Library/Application Support/Code but not sure where.
I was wondering the same thing the other day and found this while searching for a solution, so I took some time to investigate it today.
It's been a a few weeks since you posted, so hopefully this will still be of help to you.
Also, I'm using Windows and I'm not familiar with macOS, but I think it should be easy enough adjust the solution.
Location of settings
Those setting are stored in the following file: %APPDATA%\Code\User\globalStorage\state.vscdb.
The file is an sqlite3 database, which is used as a key-value store.
It has a single table named ItemTable and the relevant key is history.recentlyOpenedPathsList.
The value has the following structure:
{
"entries": [
{
"folderUri": "/path/to/folder",
"label": "...",
"remoteAuthority": "..."
}
]
}
To view the current list, you can run the following command:
sqlite3.exe -readonly "%APPDATA%\Code\User\globalStorage\state.vscdb" "SELECT [value] FROM ItemTable WHERE [key] = 'history.recentlyOpenedPathsList'" | jq ".entries[].label"
Modifying the settings
Specifically, I was interested in changing the way it's displayed (the label), so I'll detail how I did that, but it should be just as easy to update the path.
Here's the Python code I used to make those edits:
import json, sqlite3
# open the db, get the value and parse it
db = sqlite3.connect('C:/Users/<username>/AppData/Roaming/Code/User/globalStorage/state.vscdb')
history_raw = db.execute("SELECT [value] FROM ItemTable WHERE [key] = 'history.recentlyOpenedPathsList'").fetchone()[0]
history = json.loads(history_raw)
# make the changes you'd like
# ...
# stringify and update
history_raw = json.dumps(history)
db.execute(f"UPDATE ItemTable SET [value] = '{history_raw}' WHERE key = 'history.recentlyOpenedPathsList'")
db.commit()
db.close()
Code references
For reference (mostly for my future self), here are the relevant source code areas.
The settings are read here.
The File->Open Recent uses those values as-is (see here).
However when using the Get Started page, the Recents area is populated here. In the Get Started, the label is presented in a slightly different way:
vscode snapshot
The folder name is the link, and the parent folder is the the text beside it.
This is done by the splitName method.
Notes
Before messing around with the settings file, it would be wise to back it up.
I'm not sure how vscode handles and caches the settings, so I think it's best to close all vscode instances before making any changes.
I haven't played around with it too much, so not sure how characters that need to be json-encoded or html-encoded will play out.
Keep in mind that there might be some state saved by other extensions, so if anything weird happens, blame it on that.
For reference, I'm using vscode 1.74.2.

Generate starter code based on new file VSCode

Is there a way to configure some code based on a file extension when created in VS Code? I'm currently working with psioniq file header which has been pretty helpful in generating good header files, but I'm looking to take this a step farther.
When I create a new file, based on a specific file extension, I would like it to generate some starting code that I can configure. For example, I work with Verilog a lot. It would be really cool if Code could generate based on the file name.
Create new file
Code generates some code (like below) or something else that could be configured based on the filetype:
module <filename> (
input ,
output ,
);
endmodule
Anyone have any extensions they know about or resources they can point me to to implement this?
This would be a pretty easy extension to write but an alternative is snippets.
You can create keywords, based on the extensions, that when you type it it'll create all that code for you.

Eclipse Plugin Development: Adding items to a working set with the path of the item?

Hello,
I'm an eclipse plugin development newbie looking for pointers to get me started on a particular project.
I am trying to build an eclipse plugin that will automatically construct a working set from a text file that simply consists of a list of file path names. The files/items need not share any parent directories. The rough idea is represented in the following diagram:
I am not asking for the solution to this task. That's the over-arching goal. To achieve that goal, I want to conquer some smaller goals first.
With that in mind, here's the smaller goal I'm currently trying to tackle:
In Eclipse, how can I prompt the user for a single file's path, and then add that file to an existing working set?
I'm not sure where to start. Should I work directly off of the existing org.eclipse.ui.workingSets extension point? Or should I use a collection of other extension points? How do I convert strings into something that can be added to a working set? Do I write code that directly modifies the workingsets.xml file?
Even with a much simpler goal, I still feel quite overwhelmed with the vastness of eclipse extension options. There are probably many ways to go about implementing something like this, but I just need one to get started.
Thanks a bunch!
To manipulate working sets you use the working set manager interface IWorkingSetManager. Get this with:
IWorkingSetManager manager = PlatformUI.getWorkbench().getWorkingSetManager();
From this you can get a particular working by name with:
IWorkingSet workingSet = manager.getWorkingSet("name");
The contents of a working set is an array of IAdaptable objects:
IAdaptable [] contents = workingSet.getElements();
You add to the contents by adding to this array and setting the contents:
IAdaptable [] newContents
.... get new array with old contents + new contents
workingSet.setElements(newContents);
A lot of Eclipse objects implement IAdaptable, for a file in the workspace you would use IFile. You can use dialogs such as ResourceSelectionDialog to select resources from the workspace.

Provide JSON Schema for a JSON file like settings JSON in Visual Studio Code

When editing settings JSON file, Visual Studio Code suggests property names. I am assuming it's using a JSON Schema internally.
It's a very nice feature and can be useful for editing other JSON files that have a JSON Schema. I can't find an option for adding schema to a JSON file. If it's an internal feature, where it is located in the source code and can we build an extension that surfaces the feature so we can provide JSON Schema for editing a JSON? Using $schema property doesn't seem to be working.
I found out it's possible to provide those JSON Schemas. In settings.json there are a couple of examples for Bower and package.json
They are under "json.schemas".
We can also do it this way:
In your .json file, just after the first opening curly bracket, add $schema property that is the path to the schema file:
{
"$schema": "../node_modules/sp-build-tasks/schema/v1/sppp.json",
startTypinghere...
}

Issue with a topjson object in a Meteor app built with coffeescript

Apologies for the lack of precision in the question, but I'm not completely sure which of possibly many things I'm doing wrong here.
I'm relatively new to Coffeescript and also geo applications in general, but here goes:
I've got a working (simple) Meteor (.7.0.1) application utilizing coffeescript in both client and server. The issue I'm having occurs when attempting to utilize TopoJSON encoded files to create a layer of US congressional districts. (the purpose of the app is to help highlight voter suppression in the US)
So, a few things: Typically in a non-Meteor app, I would just load the topoJSON file like so:
$.getJSON('./data/us-congress-113.json', function (data) {
var congress_geojson = topojson.feature(data, data.objects.districts);
congress_layer.addData(congress_geojson);
});
Now of course this won't work in Meteor because its not asynchronous.
One of the things that was recommended here on SO was to not worry about reading the file, and to instead change the json file to .js, and then set the contents (which are of course just an object) equal to a variable.
Here's what I did:
First, I changed the .json file to a .js file in the server directory, and added the "congress =" to the beginning of the file. It's a huge file so forgive me for omitting the whole object.
congress = {"type":"Topology",
"objects":
{"districts":
{"type":"GeometryCollection","geometries":[{"type":"Polygon"
Now here's where everything starts to give me issues:
In the server.coffee, I've created a variable like so to reference the congress object:
#congress_geojson = topojson.feature(congress, congress.objects.districts)
Notice how I'm putting the # symbol there? I've been told this allows a variable in Coffeescript to be globally scoped? I tried to also use a Meteor feature called "share" where I declare the variable as "share.congress_geojson". That led to the same issues which I will describe below.
Now in the client.coffee file, I'm trying to call this variable to load into a Leaflet map.
congress_layer = L.geoJson(null,
style:
color: "#DE0404"
weight: 2
opacity: 0.4
fillOpacity: 0.1
)
congress_layer.addData(#congress_geojson)
This isn't working, and specifically (despite attempts to find other ways, the errors I'm getting in the console are:
Exception from Deps afterFlush function: TypeError: Cannot read property 'features' of undefined
at o.GeoJSON.o.FeatureGroup.extend.addData (http://localhost:3000/packages/leaflet.js?ad7b569067d1f68c7403ea1c89a172b4cfd68d85:39:16471)
at Object.Template.map.rendered (http://localhost:3000/client/client.coffee.js?37b1cdc5945f3407f2726a5719e1459f44d1db2d:213:18)
I have no doubt that I'm missing something stupidly obvious here. Any suggestions or tips for what I'm doing completely wrong would be appreciated. Is it a case where an object globally declared in a .js file isn't available to code in a .coffee file? Maybe I'm doing something wrong on the Meteor side?
Thanks!
Edit:
So I was able to get things working by putting the .js file containing the congress object in a root /lib folder, causing the object to load first, and then calling the congress object from the client. However, I'm still wanting to know how I could simply share this object from the server? What is the "Meteor way" here?
If you are looking for the Meteor way to order the loading of files, use the Meteor.startup function and put the initialization code there. That function is the $.ready of the Meteor world, i.e., it will execute only after all your files have been successfully loaded on the client.
So in your case:
Meter.startup ->
congress_layer.addData(#congress_geojson)
