Ask AI Questions About Your Codebase from the CLI With Laragenie

---



Laragenie is an AI chatbot with an Artisan console integration for your Laravel applications. It can understand your source code by indexing directory/file paths. You can then ask questions about your code such as "Describe all the model associations for the App\Models\Post model".


Here's an example of how you can configure the indexes in your configuration file. It works by indexing your configured files with an AI model using OpenAI to generate responses and Pinecone to index data:
// config/laragenie.php
return [
// ...
'indexes' => [
'directories' => ['App/Models', 'App/Http/Controllers'],
'files' => ['tests/Feature/MyTest.php'],
'removal' => [
'strict' => true,
],
],
];




Once you’ve installed this package, you can index your files, clear the index, and ask questions by running the laragenie command:


Ask questions about your code from the command line.



Note that the files you index and ask questions about needn’t be only PHP files! You can also index and ask questions about your JavaScript, GitHub workflows, etc. The neat thing about this CLI is that it’s not generic answers; it’s specifically helpful to answer questions about your unique codebases.


Using AI models is a valuable way to speed up tedious tasks. It can be helpful in onboarding developers new to a project and getting general knowledge about an unfamiliar codebase more rapidly.


This package is available on Github at joshembling/laragenie and installable via composer:
composer require --dev joshembling/laragenie

Exception "No successful match so far" after Matcher.find() == true

Matcher m = patternFoo.matcher(sFoo);

if(m.find()){
...
m.start()

}



I wonder how it is possible for the m.start() in the above code to throw the following exception:
Exception: No successful match so far
Class: java.lang.IllegalStateException
Stack trace: java.lang.IllegalStateException: No successful match so far
at java.util.regex.Matcher.ensureMatch(Matcher.java:1116)

Could anyone shed some light on this?

Updating associated items in Sequelize

still trying to learn the magic of sequelize. I've made some progress, but I'm totally stumped at how to achieve updating associated items in a clean and organized way. I am using it with postgres.


Basically I have a table "invoices". Those invoices have a table "invoiceItems" associated to them as one invoice to many invoiceItems.


Now I have a route where users can update invoices. The part I cant figure out is how to handle when they update, add, or delete invoiceItems. The front end would be able to send me a JSON object containing all of the data including the IDs for the invoice and the invoiceItems (except the new ones of course). The goal is to update the existing invoice and associated invoiceItems with the new object sent from the front end. I can use the object to create a new invoice no problem, but updating has proven very complicated for me.


My create statement works and looks like this, I would love something similar for update, but I am starting to understand that might not be possible
db.invoice.create(
req.newInvoice, {
include:[
db.invoiceItem
]
}
)



I have tried using transactions as well as mixin methods like set/add/remove etc. With limited success and anything that comes close has so many nested loops comparing the versions it makes my head spin. Is there an easier way to achieve this that I have over looked?


Here's my pared down models for you to see in case it helps:


invoices
module.exports = (sequelize, Sequelize, DataType) => {
const Invoice = sequelize.define('invoice', {
id: {
type: DataType.UUID,
primaryKey: true,
defaultValue: Sequelize.literal( 'uuid_generate_v4()' )
},
userId: {
type: DataType.UUID,
},
createdAt: {
type: DataType.DATE
},
UpdatedAt: {
type: DataType.DATE
}
},{
underscored: true
});

Invoice.associate = models => {
Invoice.hasMany(models.invoiceItem), {
foreignKey: "invoiceId",
onDelete: 'cascade'
}

Invoice.belongsTo(models.user, {
foreignKey: "userId"
})
};

return Invoice
};




invoiceItems
module.exports = (sequelize, Sequelize, DataType) => {
const InvoiceItem = sequelize.define('invoiceItem', {
id: {
type: DataType.UUID,
primaryKey: true,
defaultValue: Sequelize.literal( 'uuid_generate_v4()' )
},
invoiceId: {
type: DataType.UUID,
},
userId: {
type: DataType.UUID,
createdAt: {
type: DataType.DATE
},
updatedAt: {
type: DataType.DATE
}
},{
underscored: true
});

InvoiceItem.associate = models => {
InvoiceItem.belongsTo(models.invoice, {
foreignKey: "invoiceId"
})
InvoiceItem.belongsTo(models.user), {
foreignKey: "userId"
}};

return InvoiceItem
};




Thanks in advance for any help/ideas!

Is there a way to write a JavaScript program that enables you to Search Words in Multiple PDF Files?

I need to create a simple program/system/application using JavaScript that enables a user to search a certain word in multiple scanned PDF files. So basically a user will scan multiple files and save them to the computer as Searchable PDF Files. Then the user will upload the PDF Files into the program/system/application, that I am trying to create, where he/she will be able to search a certain word in the PDF files that were uploaded.


Basically it's just like the Adobe Acrobat's Advance Search option. I just need to create a similar program but much simpler. It's a project for school. Please help.


JavaScript is my preferred language but if you have any ideas from a different programming language, I'm open to it.


If you can send me links of blogposts or YouTube videos it will be much appreciated.


Thank you so much!


I have already tried this:
https://apryse.com/blog/indexed-search/search-multiple-documents-using-javascript but I can't seem to make it work. An error occurs in installing the package. And this is the only thing out there that's very close to what I'm trying to achieve.

What do you actually do with Laravel?

Every time I read a post about Laravel I feel like I'm using it wrong. Everyone seems to be using Docker containers, API routes, API filters (like spaties query builder) and/or Collections, creating SPA's, creating their own service providers, using websockets, running things like Sail or node directly on live servers etc, but pretty much none of those things are part of my projects.

I work for a company that have both shared and dedicated servers for their clients, and we mostly create standard website or intranet sites for comparitively low traffic audiences. So the projects usually follow a classic style (db-> front end or external api -> front end) with no need for these extras. The most I've done is a TALL stack plus Filament. And these projects are pretty solid - they're fast, efficient (more efficient recently thanks to better solutions such as Livewire and ES module-bsased javascript). But I feel like I'm out of date because I generally don't understand a lot of these other things, and I don't know when I'd ever need to use them over what I currently work with.

So my question is, what types of projects are you all working on? How advanced are these projects? Do you eveer do "classic" projects anymore?

Am I in the minority, building classic projects?

How can I improve my projects if what I'm doing already works well? I feel like I'm getting left behind a bit.

Edit: Thanks for the replies. Interesting to see all the different points of view. I'm glad I'm not the only one. submitted by /u/No-Echo-8927

}.then(function() {

})
});
});
`



this my Controller :
public function edit_data($id)
{
$id_quotation = $this->request->getVar('quotation');

$data = [
'title' => 'Edit Purchase Order',
'invoice' => $this->purchases->getPurchase($id),
'dataQuotation' => $this->purchases->getQuotationById($id_quotation)
];

Search Through exel file using a search html

function applyFilter(userInput){
/*
Use css to set the display to none first
*/
let allClientIDRows = document.querySelectorAll("ClientID-row > a");
for(let i = 0; i < allClientIDRows.length; i++){
let row = allClientIDRows[i]
let ClientID = row.getElementsByClassName("ClientID")[0]
if(allClientIDRows[i].textContent.trim() == userInput.trim()){
//You can also convert to lowercase for more accurate result
allClientIDRows[i].style.display = "inline";
}
}
}



This is the function that applys the filter to allow you to search and show what you search for and not the entire form.
i am only looking to show the searched item and not the entire spreadsheet

This is the HTML part that runs the html search part


For some reason when i run with the function its still showing all the spreadsheet. What i am trying to do is How to make a search list in which element is only shown when user search for its exact value


when you type it shows you the result but the form will be empty untiil you type


i tryed with a search function with a filter but it shows the entire spreadsheet. Maybe i am doing something wrong or messed up somewhere in the code.


the applyfilter isnt working for me maybe there is another way i can do this

Resources covering modern non-cloud (Laravel) deployment? Best practices for deploying updates, serving new features to beta-testers, reliable backups, security, etc.

Hey,

my background building Laravel apps is working on comparably small projects for a few clients that just needed more custom functionality than WordPress could offer and a handful of personal one-off projects for organizations I volunteer for. Mostly apps that you build and not touch anymore for long stretches of time.

Recently, someone approached me with a very interesting offer to develop a more complex application they'd use internally. Laravel seems suitable as no mobile app is required. Even down the road a progressive web app would totally suffice if necessary at all. Their business is on the smaller side of what can be considered a SMB, I'd estimate

Laravel Purity vs Spatie's laravel-query-builder?

I'm looking to implement an out-of-the-box solution for filtering & sorting results on my API endpoints, and I've come across Laravel Purity and Spatie's laravel-query-builder. Both are still actively being maintained and offer similar features. I like Purity's approach of defining the filter logic on the model instead of on the controller (which is what Spatie does), but Spatie's solution is a lot more popular.

Is there anyone who has tried both packages or prefers one over another for any good reason? submitted by /u/DigitalEntrepreneur_

searchQuery = questionType + " " + userInput + " "
# API Call
googleSearchUrl = "
http://google.com/complete/search?output=toolbar&gl=" + \
countryCode + "&q=" + searchQuery

# Call The URL and Read Data
result = session.get(googleSearchUrl)
tree = ET.ElementTree(ET.fromstring(result.content))
root = tree.getroot()
for suggestion in root.findall('CompleteSuggestion'):
question = suggestion.find('suggestion').attrib.get('data')
questionResults.append(question)

return questionResults

# use a Keyword for testing
userInput = "email marketing"

# Create Object of the QuestionsExplorer Class
qObj = QuestionsExplorer()
print("Keyword ideas about 'is'")
# Call The Method and pass the parameters
questions = qObj.GetQuestions("is", userInput, "us")

# Loop over the list and pring the questions
for result in questions:
print(result)
print("Keyword ideas about 'can'")

How do i tweak my YAML file so that it builds but does not deploy? I want to set up a PR Build pipeline to test build each PR

See below for my YAML code that I have in Azure pipeline, it is based off of a pipeline I created that works great for building and deploying.


I'm hoping to create a new pipeline that triggers when there is a PR to the "main" branch, and it builds the branch in the PR to see if there are any build issues before we merge it with the "main" branch. I believe the name for this is Build Validation, but I'm stuck with creating the pipeline. Or is this right and I need to handle this with settings in the build validation setup?


I tried to update the YAML so it only runs when a PR is created, I think that part is okay. But I can't seem to figure out how to cancel the deployment part. The changes I make keep breaking in the build process of my existing normal pipeline.
name: Azure Static Web Apps CI/CD

pr:

- main

How to get 30 days prior to current date?

I have a start calendar input box and an end calendar input box. We want defaults start calendar input box 30 days prior to current date and the end calendar input box to be the current date. Here is my date vars.

var today = new Date(),
dd = today.getDate(),
mm = today.getMonth(),
yyyy = today.getFullYear(),
month = ["January", "February", "March",
"April", "May", "June", "July", "August",
"September", "October" "November", "December"],
startdate = month[mm] + ", " + yyyy.toString();




The end date would be something like var enddate = startdate - 30; Obviously this won't work.



So if the current date is December 30, 2011 I'd want the start date to read December 1, 2011.



EDIT: My question was answered... sort of. Date.today(); and Date.today().add(-30); work but I need the date in the format of January 13, 2012. Not Fri Jan 13 2012 10:48:56 GMT -055 (EST). Any help?



MORE EDIT: As of this writing it's 2018. Just use Moment.js. It's the best.

The MJML correctly gets parsed as html. How can I pass it to my new Content class to display the email. The way I'm doing above is erroring out.

Typescript eslint dont not recognize object in array

Hellow i got some problem with typescript or eslint (im new in eslint).


I show code, and next try to explain the error.


types.ts
export type TSettingsIputsState = {
personal: {
label: string;
name: keyof TApiResponseProfile;
value: string;
activeEdit: boolean;
onActionButtonClick: () => void;
}[];
display: boolean;
};



component.tsx
const [profileInputs, setProfileInputs] = useState();

useEffect(() => {
const setFormData = async () => {
if (!profileData) return;
const inputs = await inputsItems();

setProfileInputs({
personal: [
...inputs.personalSettings.map(({ label, name }) => ({
label,
name,
activeEdit: false,
value: profileData[name],
onActionButtonClick: () => console.log("asd"),
})),
],
display: false,
});
};

setFormData();
}, [profileData]);



This code give me no error from ts or eslint, but when i delete name and add dummy value, the ts dont suggest me to add name, and dont not recognize that dummy shouldn't be there.


Another error is when i change onActionButtonClick: (testing: string) => void in type there is no error when no change in onActionButtonClick: () => console.log("asd")

Consider the following scenario:
I have a list of integers. I need to print all the values from the list. Can it be done using threads concept where i have multiple threads running on each item in the list and where each thread is used to print out a value rather than one thread printing all the values? I am not trying to modify any value in the list.

Transform a blurhash to grayscale

Does anyone have an idea of how we can implement an efficient algorithm (js/ts) that given a blurhash string returns the equivalent (even of reduced quality) but in grayscale?


I need it because I use blurhashes as image holders, but in a part of my application I need to display images in black and white. Thanks in advance

---



EDIT


I managed to arrive at a code like this. the problem is that the blurhashes seem stretched and deformed compared to the originals
const WIDTH = 30;
const ASPECT_RATIO = validationConfig.media.profilePicture.aspectRatio;
const HEIGHT = Math.floor(WIDTH / ASPECT_RATIO);

export function convertBlurhashToGreyscale(blurhash: string) {

const pixels = decode(blurhash, WIDTH, HEIGHT);

for (let i = 0; i < pixels.length; i += 4) {
const grayValue = Math.round(
(pixels[i] + pixels[i + 1] + pixels[i + 2]) / 3
);

pixels[i] = grayValue;
pixels[i + 1] = grayValue;
pixels[i + 2] = grayValue;
pixels[i + 3] = 255; // Imposta l'opacità a 255
}

const newHeight = Math.floor(WIDTH / ASPECT_RATIO);
return encode(pixels, WIDTH, newHeight, 4, 3);
}

Laravel Breeze with PrimeVue

I just finished creating a Laravel Breeze equivalent starter kit using PrimeVue and PrimeFlex, the inspiration was to have a starter kit that would provide a larger selection of Vue components out of the box. Feedback is welcomed and appreciated!

I'm considering abstracting this into a composer package, but decided to see if there was any interest in the idea first. Perhaps a PrimeReact version as well?

You check it out here:

add values to the array object key by clicking the button with this value react

I have three buttons that when clicked I want to add a value to a selected field that is added dynamically:
const [Fields, setFields] = useState([
{ value: null, current: true },
{ value: null, current: false }
]);



value - is the key I want to add values to when the button is clicked


current - these keys store the state of the selected field when the field is clicked on
const [Fields, setFields] = useState([
{ value: null, current: true },
{ value: null, current: false }
]);

const GetSymbol = (event) => {
const symbol = event.currentTarget.dataset.value;
return symbol;
}
const InsertSymbol = (curField) => {
curField = GetSymbol;
return curField;
}

GetSymbol(event)} data-value="A">A
GetSymbol(event)} data-value="B">B
GetSymbol(event)} data-value="C">C

{Fields.map((field, i) => {
return (

{
setFields((oldArr) => {
let newArr = oldArr.map((item, index) => {
return {
...item,
current: index === i ? true : false,
};
});
return newArr;
});
}}
>
InsertSymbol(field.value)


);
})}



if the key current is true in the current field, then you must populate the values in field.value for that field.


I.e. If you click on A and B buttons, the value of field.value will be AB.
In my code, the functions GetSymbol and InsertSymbol are incorrect.


Please help me with this!

MathML's msqrt not tall enough for fraction

I am new to MathML so please bear with me. I created the following equation:



A
B






But the results show the sqrt only over "A". I want it to be taller so it is over A and B.


I tried playing around with changing the css file, like margins and padding, but nothing seemed to work.

What's a better solution to tackle this problem - export / clone and restore for complex nested relations

You'll have to excuse the confusing title, I was trying to come up with a way to describe the many components to this challenge I'm trying to iterate on and come up with a better solution then the existing one.

Allow me to summarize. Our company provides an architecture design tool that, to simplify, allows customers to create projects, which contain architectures, which contain elements, interfaces, which contain requirements, tests, which contain.. etc etc. Lots and lots of nested relations. A project, after a few months usage, can easily contain thousands of records spanning two dozen tables, representing one-to-one, one-to-many and many-to-many relationships.

Currently all tables use an auto-increment numerical ids.. your standard stuff. Most tables also contain a project_id table which itself is just an integer.

Enter feature #1. The ability to export your project with all of its nested relations. This was simply enough.. we just load our project and recursively load all of its relationships, and then we just dump that whole thing as an array to a json file. This saves a full copy of the project with all of its relations represented by the values of thousands of primary keys at the time of export. Easy.

Enter feature #2. The ability to clone the above extremely complex project. Currently, we export the above, and then we have this complex script that iterates over every level of relation from the json dump and creates a new copy of everything. As it's doing this, it's storing all the reference primary ids from the json dump, and creating a relation map of sorts that it then uses to re-attach all the relations but using the new ids that are being created thanks to the auto-increment ids of the new copies.

Read that again if you must.. this one is a bit of a nightmare, this is not a piece of code I am happy with right now and is the constant source of issues. Before I describe what I think is a better way.. let's talk about the last feature.

Enter feature #3, the ability to restore a previous import (you can also think of these imports as a versioning system but not just for a single model but for a huge project). When you restore a project, you're overwriting the existing project and you must end up with the full working project with its thousand nested relations.

In a way, both cloning and restoring results in the same project state, but in the former case you end up with two projects where the cloned project will of likely diverge from the original, and in the case of restoring you still only have just the one project. I haven't done the restore feature yet.

Keeping in mind that the same database houses hundreds of these complex projects.. and each table having tens of thousands of records with different numerical ids that belong to different projects.

So restoring a project with the current system.. for example taking a project which at the time of export had 1000 nested records and now the current project has 3000, but after restoring we need to be back to 1000 (as an example).. this operation is quite a tricky one when using auto incrementing ids.

So voila.. this is the problem I'm currently facing. And I was just thinking aloud tonight of how to do this in a much better way.. and I'd love to hear all your thoughts about it before I talk about my new idea.

Really appreciate your thoughts actually : ) I don't come to Reddit often for coding problems but this one is a bigger task that's been on my mind a lot.

Oh and btw of course I'm using Laravel 10 here.

The first thought I had is that this could be dealt with with a NoSQL approach. But I kind of dread NoSQL and no way do i want to suggest that we move away from MySQL to something like Mongo at this time so we must stick to using a relational DB. I also don't want to use a different DB for each project. I am already dealing with 40+tables and having hundreds of dbs to manage would be a big nope.

The second thought I had is: use composite primary keys everywhere. Each project has a unique hash for a primary key and then everything else that is attached to it has a primary key that makes use of the project's unique key. Ignoring the pains and caveats that come with using composite primary keys.. this appears to make everything waaaaay easier. The export feature is the same as before. Cloning just involves creating a new project hash and then replacing it everywhere before inserting every records as is.. no need to relink things it just works and we just need to change one key.

And same for restoring.. we just wipe absolutely every record that contains the project key that's being restored and then we just restore the dump as-is.

Am I missing something or is this a waaay better solution?

The caveats with composite keys is that it can be less performant when making queries and it requires a lot of refactoring. Sometimes dependencies don't play well with composite keys.

I can't really think of another approach at the moment. What do you think about the composite key approach?

if you read this far.. I hope you're finding this mildly interesting! Thank you for making it this far and thanks a lot should you decide to share your wisdom developer to developer ;-)
