Title: What you're doing using Lazarus?
Post by: Sanem on September 04, 2021, 09:33:40 am
Hi everyone,
I was wondering, what you're doing by using Lazarus right now?
Like what projects are you making with it, what aspects you're depending on etc.
Regards

Right now? I'm not, I'm using FreeCAD and a 3D printer to produce some precision insulators/guides.

In the wider picture: data collection from remote embedded equipment, data presentation and forwarding on behalf of customers, local test programs in support thereof, embedded scripting using a derivative of Meta-2 that supports language extensions. Various things related to high-precision timing, camera control and reliable communications. Much else.

Longer term: an embedding of Python into Lazarus to support various Inkscape addons. Hopefully port Tree Meta to augment/replace my long-term use of Meta-2. Much else (Deo volente).

Sorry to be a party pooper.
I never use Lazarus.
Freepascal with a simple ide (Dev-Pascal ide for instance) does me.

I never use Lazarus.

Horses for courses. Particularly if interfacing with a piece of workbench equipment I try to support both GUI and non-GUI where possible. That typically means two separate programs, but I also try- where possible- to have a single binary which runs non-GUI if there are command-line parameters.

I'm working on a data entry and graphical display program for my home lab. Next I'm going to try to port my existing C microcontroller programs to use Pascal on ESP8266. For those microcontrollers I will also move away from web based access and use a GUI program instead.

I really don't want any of my projects to depend on browsers at all anymore.

In February 2016 I started the Solpage project (https://ditrianum.org/solpage.htm) with Lazarus. It is still being maintained with optimizations and new features. It arrived at version 7.4 just a few days ago. One feature, which was added in July 2017, is the SSGI graph (https://ditrianum.org/ssgi.htm), which uses the TChart component. Without Lazarus I think the only other reasonable option to create this project would have been Delphi.

Two additional programs I made with Lazarus in 2019 are AeLog (https://github.com/ditrianum/AeLog) and AeView (https://github.com/ditrianum/AeView), both available on GitHub. I use these programs to provide real-time atmospheric electricity data on the website (https://ditrianum.org/atmosphere.htm) by reading measurements from Arduino devices.

Maybe good to know is that the United States Geological Survey (USGS) and also scientists on Twitter such as Ronald Karel from GeoCosmo showed interest in the data produced by these software projects.

I am using lazarus and Firebird 3.03 to develop a project for an ISP which has approximately 15,000 users which are managed by 136 Mikrotik Routerboards.

The project consists of 8 programs which fulfill functions from the request for internet service, scheduling of activities, creation of user subscriptions, billing, activation of internet service, service outages, tickets, inventory, among others.

The programs are used 24/7 and can have up to 100 users working at the same time.

I am using Lazarus to develop some (simple) games:
 + Draughts (checkers) a game I wrote for delphi; ported to Laz this year.
 + "Qnoc" a simple empire building game; works ok except the AI players keep building bridges without building roads leading to them. ;-)
 + Holdem (poker) a game my brother started 20+ years ago in TP; works ok except the AI players are pretty manic at the start of the contest. :)

A note application, modeled after the original Tomboy Notes that used Mono and GTK+. 

https://github.com/tomboy-notes/tomboy-ng

20K odd lines of code (well, I use a lot of comments too).  I used Delphi 1 and 2 way back, did not write any application code for a long time. Definitely do NOT regret my somewhat controversial decision to write tomboy-ng using FPC/Lazarus.

Like Pascaldragon I'm principally a FPC devel, and have a lot of small tooling (both work and private)

My job is at a machinebuilder which is  a Delphi shop for PC work (the embedded boards we use are programmed in C) , but I converted everything except the main apps themselves to Lazarus.

The minor ones of that being various small microservices (that e.g. sync files to network drives, http getter apps, some dedup and file/drive scanning tools, various comport and indy programs (older embedded boards communicate using serial, newer via UDP) and file format conversions etc).

The larger ones are a small 20 table CRM connecting to postgres and some tools for our embedded work (a loader for the KICAD format to generate export files for our pick and place machine, and an headergenerator that shield board layout details from the actual programs).

Some of the reasons to use Lazarus while we have licensed Delphi is Delphi installation limits and installation speeds.  Lazarus is much faster and easier to install (can be copied components inclusive even)

For the past few years I am heaviely into trying to utilize the language and features for new paradigms and workflows that are prevalent in other languages (e.g. my most recent apporach STAX tries to implement python or javascript style co-routines in pascal).

Sadly most of the time my projects come to an early death due to the fpc throwing one internal error after another, or simply aborting the compilation because too many generics confuse it, or there is another bug that makes what I wanted to build impossible. This usually results in me not using fpc/lazarus for the next 4-6 months until I find another project to dive into

I use Lazarus because it allows a Delphi-exile to continue using a productive language, and tools with which I am familiar. Like Indy, IBX, Firebird SQL, etc. I use it to write general purpose applications for internal use (like accounting, point-of-sale, inventory control, bill of materials).  I also use it to write software for external clients (like positioning software for solar arrays, LP tank metering, geocoding utilities).
Title: Re: What you're doing using Lazarus?
Post by: jamie on September 05, 2021, 07:26:06 pm
We use Delphi at work directly on the machines so each machine has it's own  registered file with Delphi however, the policy put in place to keep these installs running without license timeouts in the middle of production because some engineers like to run the apps from a Debug state are causing lots of issues. And on top of that, our network is a closed system and is very hard to reinstate updated license  info.

 So we have been attempting to port these apps over to laz but only the GUI ports are going well. Other aspects of the apps require DLL's with protocol converters, DeviceNet, ControlNet, EtherNet, ModBus serial etc do not work with fpc after 3.0.4 for unknown reasons.

 so currently these DLL's are still Delphi's...

  But all in all, the GUI part seems to work well although a little more resource hogging .

I've ported two commercially available apps from Delphi to Lazarus.
The first that does nonlinear (& multiple linear) regression analysis (curve fitting) is called FitAll.
It has been used by various researchers to characterize the current-voltage behaviour and performance of solar cells and modules, the binding of possible cancer treatment drugs to DNA and many other tings.

The second is a Simple Inventory Program, SIP, that uses SQLite as the database. This program is useful for home inventories that can be helpful when moving, making insurance claims and in the fullnues of time to give to ones executor.

Currently these are Windows only apps.
More information and an evaluation edition of the programs is available at http://www.fitall.com/ .

The first commercial version of FitAll was developed using TurboPascal v2. Later Delphi versions made it possible for users to develop addon function library dlls with FPC and Lazarus as well as Delphi.

Hi,

In fact, I am working on a lot of projects in scientific computing using FPC/Lazarus, some developed in FPC/Lazarus from the start, and some which I have developed in Python and that are now being ported to FPC/Lazarus.

Among them are:


FPC/Lazarus and R currently supports all my needs in software development and data analysis.

With best regards,

@glorfin,

Thanks for asking, you are welcome.

For my own data analysis I use R separately, of course. Some of my FPC/Lazarus applications call R (with automatically generated scripts, created by the application from user input of parameters) and then present the results back to the user (as plot images and text reports). The applications therefore act as shells for running specialized analyses using R.

With best wishes,

But @MarkMLI, simply calling R from an FPC/Lazarus application as an external process is enough and works quite well!

I love embedded systems. Fpc+Lazarus always always amazes me. I have to spend more time investigating FPC+embedded.

In other way I use Lazarus+FPC to make tools to make my work easy. Usually apps to check/repair/analize programs from industrial machines. Always for me use or internal use in my job.

Now I convinced my boss, that we can make more things. Recently I made a app that works with industrial camera from Allied Vision manufacters, and comunique with a python app because we use IA to check the photos for a customer. I have to say, that at the begining of this project, my boss said me that we should use python for all app. But I make some test I demonstrated that FPC is faster and easy to comunicate with the camera. Our test in nvidia jetson nano, FPC vs Python was that FPC was around 10 times faster. And a important thing, was tha FPC used a lot of less memory that pyhton. And manage very good  and fast the garbage. Pyhton takes time to remove garbage, only with it idle. And that was not good for us, because jetson nano has limited resource, and our app had to run with out idle because the industrial process was fast, around 10 pieces per minute.

Unfortunately I could not use FPC for IA recognition, so that part of the app was written in Pyhton. And finally we had to move every thing to PC, because python eats a lot resources. And of course I had not programning again, i only compiled  :-X

Actually I making a app to control a ABB robot using webservices which use Rest api.

The main reason for use Lazarus+FPC because is easy to easy, good results and free. Other comercial solutions can not considered, because we are not a software company and our maket is industrial machines. So buy a comercial solution is not profitable. Also I learned Pascal in the school (also C, Cobol, etc) since I love Pascal.

PC applications to assist in developing embedded devices:

* wrapper for JLink to upload firmware to the devices
* wrapper for our own programming- and test-adapter
* bootloader client for our bootloader to upload firmware to the devices
* A subset of IO-Link master functionality to interface with IO-Link devices
* GUI-Tools that assist during firmware development and debugging, to interface with the device, log realtime data and control various functions
* GUI-Tools using any of the above to automate production, calibration and testing of the products
* GUI-Tool to control a 5 axis Flash- and Test robot
* GUI-Tool to control a 6 axis (2 of them dispense pumps) potting glue dispenser
* Firmware-updater or configuration-tools to ship to customers

Currently working with 3 developers on these various projects.

When we are not using Lazarus/FPC for GUI stuff we are using C (for the firmware) and Python (for various scripting stuff, code generators, etc).

Everything (Developer workstations and production machines) is running on Linux.

Nice these are pretty good usages, Can I see a preview or link or anything to demonstrate these usages?

These are all tools for internal use in the company only, and even the firmware updater I talked about (it implemented a TFTP server to update the firmware of a Toradex SBC) was for use by the contracting entity only, so I cannot share it.

The only thing so far that has publicly come from it so far is my hidapi binding (which I am using to access some of our usb connected internal gizmos) is here: https://github.com/prof7bit/HIDAPI.pas (and the counterpart on the device which implements a HID device driver on a KL25Z (NXP Kinetis) is here: https://github.com/prof7bit/frdm-kl25z-minimal-usb-hid

And some early stuff from me that was used when we still used AVR and the only means to debug was UART was this: https://github.com/prof7bit/DebugTerminal (now unmaintained, I don't use it anymore)

I am trying to help the FPC/Lazarus projects as best as I can with bug reports or merge requests, because I rely on these tools every day, and I want them to become better every day. Sometimes I spend entire days of company time to hunt down a Lazarus bug or bisect a regression to help fixing it because we all need it to function properly.

Mainly, I use Lazarus in my projects associated with micro-controller: with the Pascal software (only Windows) I can design sequences to control some light and servomotors to do some animations. These sequences are then injected into the code of the micro-controller.
I also developt some application for entertainment purposes


I'm interested in your entertainment applications ;)
Can I see a link or preview or sth like that

Hobby program to play Othello (Reversi).  Mostly satisfied now but still tweak it when an idea comes to mind.

That's cool, can I see it?

Sudden task - video surveillance system, based on libvlc. It works. At least 64bit version. 32bit one reports out of memory. The biggest problem - my program hangs, when running in IDE. So, no debugging. Just writing working code straight way.

There was a thread a few weeks (?) ago relating to this. I think it got to the point where it was agreed that a program worked using the IDE's "Run without debugging" facility, but I can't remember whether anybody explicitly tested a different debugger (i.e. fpdebug rather than gdb).

I use Lazarus for the development of a cross platform and open source application launcher. I used to use Delphi, but in the last year I have ported the source code to FPC + Lazarus and have finally ported everything to Linux with no major problems.

Somehow it's related to problems with threads, as, I guess, libvlc creates separate threads for it's players. Everything works, if only one player is used. But several players hang as soon, as they start playing. How can I switch to other debugger in Lazarus?

Right now I have all projects on halt due to lack of time but I'm with 3 different things:

An IDE.  I think I can release a fist alpha version right now.  It's called Multi Language Scriptable Development Environment (MLSDE).  The project website (https://www.sf.net/p/mlsde).

The Allegro.pas (AKA Allegro4Pascal), a wrapper to use the Allegro game library with Free Pascal and Delphi.  Also I should release a new version with the latest additions and fixes. The project website (http://allegro-pas.sf.net/).

And finally, the Mingro Game Engine, designed to create old-school games.  Version 1.a.4 were quite complete but I'm rewriting from scratch because the component-based design didn't help so next 1.a.5 will have a more classic design (using static classes and a few objects though). The project website (https://www.sf.net/p/mingro).

Few days ago completed an application that manages the work of a robotic arm. See this https://www.youtube.com/watch?v=FdPu8XA_B-Y (https://www.youtube.com/watch?v=FdPu8XA_B-Y). This is my hardware platform to develop some control algorithm/procedures/functions. Thanks some people from THIS forum was possible to start years ago experiments with Rapsberry Pi. Thanks.

Curious, was that all done on the RAS or was the host GUI in a PC and talking to the RAS?

GUI on RAS, talk with four ATMega328 (i2c).
