PdfgrepGui
This is a simple GUI for the command line tool grep and pdfgrep
This program is a GUI for the command line tool grep and pdfgrep. Pdfgrep search text in multiple PDF files and grep can serach text in multiple text files. You can use regular expressions for the search (https://en.wikipedia.org/wiki/Regular_expression). This GUI and the command line tools work without indexing. The following options are used: -i (ignore case) and -F (fixed strings), -n (Print page number or output lines) and -H (Print the file name for each match) from the command line tool. The -r option will be done by the program itself. Performance: This GUI works well when searching in several hundreds of documents (depends on the speed of your computer and the length of the documents). Config Dir: [homedir]/.config/pdfgrepgui Available Languages: - English - German You can add your own language by editing the file [homedir]/.config/pdfgrepgui/language.set -

Avocado programming language
Avocado Polish programming language
The Avocado language is compiled and currently allows for the creation of console applications. Work on Avocado and the integrated development environment (IDE) began on February 19, 2025. A unique feature of this language is the ability to write commands in Polish and English, compiling code into .exe format. The language is freely available for commercial and non-commercial projects. The Avocado source code is available under the MIT License on GitHub. Avocado is transpiled to Free Pascal and then compiled by the FPC compiler, making it as fast as C or Rust, but with syntax reminiscent of Python. The Avocado IDE interface has been translated into 30 languages Official website: https://avocado.dimitalart.pl/ Documentation: https://avocado.doc.dimitalart.pl/ Source code https://github.com/Programista-Art/Avocado 🥑 Hey! If you like my programming language Avocado, support the project on Patronite 👉 https://patronite.pl/programista-art Every bit of support means a lot. -

vHDL Obfuscator GUI
vHDL Obfuscator is an small GUI to obfuscate and reformat HDL files
VHDL and Verilog HDL are standards languages for hardware description. Sometimes is necessary to share the source HDL file but maintaining a little level of control and protection of the intellectual property. This tool generate obfuscated code that is almost unreadable to humans, but is still readable to compilers and simulators. This tool use GHDL (https://sourceforge.net/projects/ghdl-updates/), HDLObf (https://sourceforge.net/projects/hdlobf/), Icarus Verilog (https://sourceforge.net/projects/iverilog/) and was created in Lazarus (http://www.lazarus-ide.org/) -

LuaToExe
Embedded a lua script in an executable without LUA DLL (one file)
Builds an executable containing all the files of a LUA application. This executable will be autonomous, it will include all the resources of the application. This program checks, compiles each LUA unit, searches for "require" and dependencies, it automatically includes the necessary modules. It can also integrate other types of files: DLL, Exe, images... The work is simplified by adding pre-compilation directives. -

CtoPAStom
C to Pascal converter to port math routines in Lazarus/Delphi.
I looked for a C to Pascal converter but everything I found was just some simple string replacer. So I developed this syntax interpreter. It was born to convert C algorithms included in R language sources to Lazarus. So it converts just functions ad NOT .H files. It tries to do a ready to compile convertsion. I put my project here because I hope that someone would continue the development. For me it does everything I need and I will not upgrade this project anymore. The use is simple, you past in the left area the original code and you take the PASCAL version from the right area. It is a GPL2 software. Goodbye! Tommaso Fantozzi
