KDevelop 5.4 released

We are happy to announce the availability of KDevelop 5.4 today featuring support for a new build system, a new scratchpad feature, analyzer support from Clang-Tidy plus a bunch of bug fixes and wee improvements.

Meson

Projects using the new rising star in the build system scene, Meson, can now also be managed with KDevelop, thanks to the work of Daniel Mensinger.

Current features are:

  1. Native support for Meson projects (configuring, compiling, installing)

  2. Support for KDevelop code autocompletion (plugin reads Meson introspection information)

  3. Initial support for the Meson rewriter: modifying basic aspects of the project (version, license, etc.)

Meson project configuration

Support for adding / removing files from a build target will follow in future releases of KDevelop.

Scratchpad

Thanks to the work of Amish Naidu there is now a tool to keep "scratches" of code or text to experiment or quickly run something without the need to create a full project.

The plugin adds a new tool view, which maintains a list of your scratches which you can compile and run. The data from scratches is managed and stored by KDevelop internally but is presented as regular documents in the editor giving all the editing convenience of e.g. code-completion and diagnostics. Commands used to run the scratches are saved for each scratch, while new scratches are pre-set with the last command used for that file type.

Scratchpad

Clang-Tidy

The plugin for Clang-Tidy had been developed and released independently so far, but starting with version 5.4 is now part of KDevelop's default plugins. Learn more about the plugin on Friedrich Kossebau's blog.

C++

More work was done on stabilizing and improving our C++ language support, which uses a Clang based backend. Notable fixes include:

  • Add working directory to clang parser. (commit. code review D22197)

  • Clang Plugin: Report some problems from included files. (commit. code review D18224)

  • Make it possible to select -std=c++2a for our language support. (commit)

PHP

  • Always set maximum file size for internal parse job. (commit)

  • Bypass the 5 MB maximum file size limit for the phpfunctions.php internal file. (commit)

  • Fix linking with ld.lld. (commit)

Python

The developers have been concentrating on fixing bugs, which already have been added into the 5.3 series.

There are no new features compared to 5.3.
