MVP made easier.

[cdbc]

Hi Y'all
New featured binary & source releases are out now - 14.21.04.2025 - get it from gitlab.
I've been working on a small utility, for making programming after the MVP-doctrine, a lot easier ...and now it's done.
It simply sets up a project directory structure, as well as providing and connecting the most basic 'boiler-plate' code and units, into a compilable project for you to work on...
As the title says: MVP made easier 
For people running Linux with Qt5, here is the release:
- 14.21.04.2025 binary + en-file & i18n.cfg
For everyone, here is the source release:
- 14.21.04.2025 source code release -> new transaction-factory + a 'common.consts' unit + 2 new example transactions

For that, I've setup a releases section on my gitlab,
where you can find the executable & ini-file, right here: mvp-setup
I've released the source-code, because I think it's  finished. Please comment here, let me know what you think 
edit: This little app, runs *only* in user-space and writable areas, no 'su' needed. It only writes in the directory you point it at and in 'GetTempDir' for a log-file.
Have fun 
Regards Benny

Hi Does this mean that I don't have to make a setup tool anymore? I had started but I haven't gone far yet. Will be testing your tool soon.

Hi Hans
Welcome back from holiday 
I was making the demo app and one thing led to another...  You know, the ideas kept popping up...
Was waiting to hear, how your efforts are coming along, because I don't want to trample all over your code, as it were... 
So therefore that binary upload, good thing too, 'cause I downloaded the zip myself and fired it up, works flawlessly here  Started developing a small test-app with some streams on the skeleton ...and lo-and-behold: I found 3 minor oversights in the 'boiler-plate' code, they only show, when you're trying to setup the /new/ 'Self-Committing' transactions -> 1 missing SGUID and 2 'uses' relocations.
So far so good 
So what do you say, wanna see the code?!? (disclaimer: it's a right mess, rigth now) If so, I'll prepare a preliminary zip and post in /our/ other thread...
Regards Benny

Hi,
I do not mind. I already had an idea to revive my own app and I gained some vague ideas for new things during the holidays. So still plenty of things to make. 
After the holidays I haven't really opened Lazarus much yet. too busy with other things, that's why I hadn't made myself heard yet.

I'm certainly curious about the code you have so far.

Hi
Okidoki, I'll fix the bugs and then prepare a zip... 
I'll post it in the other long thread, 'cause it belongs there, spirit-wise 
Regards Benny

[Hansvb]

Cool. I will see it there.

Hi
New binary version out now, please see the 1.st post in this thread...
I'm working on "gitlab'in" the source-code release, stay tuned...
Regards Benny

Hi
That's it folks, source released on GitLab Have fun 
Regards Benny

[Hansvb]

Great. Thanks.

Hi
Sorry guys, as much as I want to write flawless code, mishaps *does* happen... 
In this little piece of code:

Code: Pascal  [Select][+][-]

1. function TcsuModelMain.LeftWord(const aStr: string): string;
2. var li: integer = 1;
3. begin { pick the left-most word in a string }
4.   Result:= aStr;
5.   if Result = '' then exit;
6. ///////////// below a range check error can happen /////////////////////////
7.   while ((not (Result[li] in [#9,#13,#10,' '])) and (li <= Length(aStr))) do inc(li);
8.   SetLength(Result,li-1);
9. end;

The fix provided by @Hansvb is easy enough:

Code: Pascal  [Select][+][-]

1. while ((li <= Length(aStr)) and (not (Result[li] in [#9,#13,#10,' ']))) do inc(li);

The bigger problem however, is that this code is also /produced/ by the app, so it had to be fixed in the /blob/ as well... 
I's all good and fixed now and a new version of the source-code has been uploaded to Gitlab. I will upload a new version of the binary during the day...
Bugfixed version is 8.06.08.2024

Hi
mvp-setup just got a new 'istrlist.pas', so I've refactored 'model.main' to use these new features. It makes no sense to just use it in the app, thus the new 'istrlist.pas' is to be found in its product as well \ö/
Get it while it's hot, version: 9.21.08.2024 is here.
Have fun & regards
Benny

Hi
Right, maybe a small example of what *little* it takes, to make a project, made with 'mvp-setup', support i18n, i.e.: multiple languages, is in order.
Attached is a /20 min/ example, very crude, but hey...
The changes touches 4 units: view.main, presenter.main, model.decl & model.main; and introduces 3 extra files. Makes use of the new features.
In the source, just follow this: "///<- i18n" in the comments
Have fun & regards Benny

Have you thought about using PosSet/PosSetEx instead of iterating through the String?

Hi Zvoni
Frankly no, I didn't know of them till now 
They look right for the job, thanks for bringing them to my attention.
I just coded it from first principle and honestly... how would you avoid the iteration, when the code in StrUtils looks like this:

Code: Pascal  [Select][+][-]

1. while (j<=i) and (not (s[j] in c)) do inc(j);

Huh? Didn't even look at the source of PosSetEx
That said: "Great minds think alike"
... so, Kudos to you for getting it right in the first place (even with the amendment to avoid range-check-error)
