• g++ (SUSE Linux) 7.5.0

Other tools

The project contains configurations for the following tools:

• Doxygen
  You can use the Doxyfile to create a full source code documentation.
• Cppcheck
  You can use Cppcheck with the included config file to perform a static code analysis.
• cpplint
  You can use cpplint with the included config file on the .cpp and .hpp files in the src folder.

FAQ

How do I build HEdit on Linux?

Assuming your build environment for C++ is ready, just go to ./build/make/ and execute make. Otherwise you need to install g++, libncurses5-dev and make.

How do I build HEdit on Windows?

Using Visual Studio, just go to ./build/vs19/ and use the solution file hedit.sln. You will need to have "C++ build tools" installed.

Do I need any external libraries to build HEdit from scratch?

No, the only dependency is ncurses (and only if not using Windows). For the tests, the Googletest framework is used.

I can see there are tests but they are not built using the Makefile. Why?

Because the tests are currently only built using the Visual Studio 2019 solution.

Why is the first version v4.2.0?

Because the project is quite old and was just moved to GitHub recently.

My screen is quite large, can I edit more than five files simultaneously?

Yes, but only by modifying the source code. You need to change the constant HE_MAX_EDITORS and rebuild HEdit.
