Qt5 editor ported to bacon

[bigbass]

Hello


This was more involved to put as a simple demo
so here it is a real but small text editor




added tool tips
qt5-editor-1.1.tar.gz (69.43 KB)



bacon with Qt5 are working nicely together!


it is a start many things we could add in later
hopefully bacon syntax highlighting ... but not tonight

Wow! That looks really good. I am going to give it a try shortly.

Thanks Joe,

Hi Joe,

Well, I had to change only one line of code:

PRAGMA OPTIONS -Wno-write-strings -Wno-pointer-arith -I/usr/include/x86_64-linux-gnu/qt5 -fPIC


...and then it compiled without problems. All functionality works, and its just amazing how small the code is.

The only thing left for BaCon would be the syntax highlighting. As you know, I have implemented this before manually for the FLTK editor. Looking into how it works for Qt...

Hello Peter

thanks for the x86 line I added it and commented it out
in the main code just now

a minor bump 1.1 has tool tips



if you want to add the bacon highlighting manually perfect!

I was taking the easy way of thinking and was going to add kate's syntax highlighter
but still sorting out the how to go about it then the next step would be to add bacon syntax to
kate's options

Dear Joe (and Peter),

Ain't that a little beauty! Thanks. And the binary is also tiny. Well done!!! I have added 18 little svg images to replace the original pngs. They work.

images.tar.gz (2.83 KB)

And a similar (but slightly prettier) set:



To use them, simply change the *.png extensions in the source to *.svg. The names are the same.

images-vov.tar.gz (4.46 KB)

With kind regards,
vovchik

[bigbass]

Hello vovchik


Thanks!

they look good and are smaller in size and svg format

there are still some figuring out things
with the Qt world to do but the good part is
it does work with bacon and a lot of documentation and demo examples
to keep anyone busy for some time

I got about 95% of the syntax highlighting for the Kf5 (from kate) backend working with bacon
via recycling the FreeBasic.xml
this should work with anything that uses kate as the backend or Qt apps


there is a readme there also
sourceforge.net/projects/bacon-qt5/files/syntax/


sudo apt-get install libkf5syntaxhighlighting*

that will pull in these

apt-cache search KF5SyntaxHighlighting
libkf5syntaxhighlighting-data - Syntax highlighting Engine - translations
libkf5syntaxhighlighting-dev - Syntax highlighting Engine
libkf5syntaxhighlighting-doc - Syntax highlighting Engine (documentation)
libkf5syntaxhighlighting-tools - Syntax highlighting Engine
libkf5syntaxhighlighting5 - Syntax highlighting Engine





if you want to manually change all default qt themes
and make thing look really good and fast install some qt themes then
sudo apt-get install qt5-style-kvantum*



export QT_STYLE_OVERRIDE=kvantum

default gtk2



export QT_STYLE_OVERRIDE=gtk2


or maybe
export QT_STYLE_OVERRIDE=adwaita

Hello


I updated the freebasic.xml with all the functions$ for example LEFT$, CHOP$....
got kate working with bacon
and changed directories for the freebasic.xml file to use KF5

I updated the readme and the freebasic.xml in the above post



P.S I compiled the baconized freebasic,xml into the
KF5/KSyntaxHighlighting source code
now kate reads *.bac with color


....

Thanks Joe,

The 'bacon.xml' file looks strikingly similar to the GtkSourceView definition. But indeed, the QT5 way of setting syntax highlighting is much more complex. Programmatically, it need a QTextDocument and not a QTextEdit, for example. It's a whole new API and it is going to take some time to get used to...

[bigbass]

Hello Peter

Programmatically, it need a QTextDocument and not a QTextEdit,

Yes exactly in the end we need to get the highlighted
text into a Qt widget somehow


but there are some presteps needed to get there

I got a minimum cli syntax text highlighter working with bacon code
I think a working demo expresses the idea better there is a lot of code to sort though

The 'bacon.xml' file looks strikingly similar to the GtkSourceView definition

I re used your bacon keywords list and adapted them to the kate xml format
they are very close in idea one advantage is we can use the DOLLAR SIGN $
with the keywords and added the bacon
language name="BaCon" version="5" kateversion="5.1" section="Sources" extensions="*.bac" mimetype="text/x-bacon"

now bacon has a
text/x-bacon


the first step to get there using kate KF5SyntaxHighlighting the code gets compiled into an "indexer"
then all the xml files are compiled into that indexer at the low level
I wrote the bacon.xml without using freebasic (the second attempt using v5.60.0) and added it into the official source code
compiled the indexer (we dont get an option for BaCon because that part is in the kate GUI code)
but the *.bac mime type works
but it is a hidden feature at the moment just for us



compile this then
./highlight bacon.bac

with bacon.bac in the same folder for testing

here it is in action

Dear Joe and Peter,

I found notepadqq a few days ago. The source is here:

source

It uses qt5 and looks rather like geany.

With kind regards,
vovchik

[bigbass]

Hello vovchik

Thanks for this and any other qt based text editors
there is a lot of working code we could use


I had some big troubles with qt chrome web engine
tried to build it from source using git and it ran my system full
and locked up ! well I decided to start with a new bullseye rpi os

and this time document what is needed for qt better

so I am in the process of starting again clean


Joe


------------------------clean----------------------------------------


#I keep the latest bacon syntax for kate here

sourceforge.net/projects/bacon-qt5/files/syntax/



#you have to recreate those folders if you dont have them
mkdir -p $HOME/.local/share/KF5/syntax-highlighting/syntax
mkdir -p $HOME/.local/share/org.kde.syntax-highlighting/syntax


#then place the freebasic.xml inside the syntax folders

cp freebasic.xml $HOME/.local/share/org.kde.syntax-highlighting/syntax
cp freebasic.xml $HOME/.local/share/KF5/syntax-highlighting/syntax


#for KATE
sudo apt-get install kate
sudo apt-get install libkf5syntaxhighlighting*


now kate will automatically add the correct syntax highlighting
for bacon.bac files select freebasic
from Tools->Highlighting->Sources->FreeBASIC





#just in case you are missing some deps for Qt these will pull in almost all
sudo apt-get install qtbase5-dev
sudo apt-get install qtcreator




====================advanced use========================================
#advanced use if you compile from source kf5syntaxhighlighting
and drop in bacon.xml into the data/syntax folder
then complile and install
bacon *.bac will work without selecting
freebasic from the menu in kate but it can be built into the indexer
=======================================================================

Hello Peter and vovchik

some good news
I updated to debian bullseye
and that gave me the needed Qt version of 5.15.2
now a lot of source code will compile correctly!
and it has qmake 3.1

I am still going to avoid compiling chromium web enginefor awhile

more good news I updated this code
basic-converter.proboards.com/post/14480

*I now realized I made changes to the source code headers
to get the demo to compile but didnt remember that until
I started on a clean box with the default headers again

now it should work out of the box with no compiling source code packages

Just a tip to remember if this happens to me again
I had to add to the PRAGMA OPTIONS and give it the path to look for

Joe

[bigbass]

Kate now has bacon syntax highlighting working
basic-converter.proboards.com/post/14482


but in the freebasic.xml file you can't or shouldn't set colors if you follow the rules
because kate has a very nice GUI that allows you to customize the color theme

well I got used to my color picks for geany with bacon syntax highlighting
so I tried to clone the overall feel of that

and created a style.theme called Bacon Geany feel.theme
Bacon Geany feel.theme (5.13 KB)

it shows up as a compressed icon but it is NOT
it is just a plain text file you can even open it and read it


now all you have to do is
in the main window menu of kate
Settings---->configure kate---->color themes----> IMPORT

then select the Bacon Geany feel.theme

and a preview of the look
its very easy now to make it look however you prefer
by using the kate GUI color themes tool
and you can share themes with very little effort needed

Joe

[Pjot]

Thanks Joe,

Looks really good!

BR, Peter

[bigbass]

Hello Peter



thanks
we should be able to add syntax highlighting to
our qt projects I'll try to do it in just qt first
and if all goes well there then port it to bacon

this is an ongoing work in progress
little by little

Joe
