CodeLite is a powerful and lightweight IDE specializing in C, C++, PHP and JavaScript. Its features include:

  • Generic support for compilers (for example Clang)
  • Built-in GDB support
  • Database-based code completion mechanism
  • Syntax highlighting for C/C++, Java, Perl, XML, Makefile, Lua, Diff files, PHP, JavaScript, Python, HTML, and ASP
  • Text folding
  • Bookmarks
  • Find and Replace
  • doxygen comment generator

CodeLite is in the official Ubuntu repositories for all currently supported versions of Ubuntu, so it is also installable from the Peppermint OS repositories with the following command:

sudo apt-get install codelite  

There won't be any learning curve with CodeLite for anyone who has experience using CodeBlocks. Also see CodeLite IDE - Forums.
