clang-format formatter plugin
A new source code formatter plugin based on clang-format / LibFormatt.
- (re)formatting source code
- using the predefined LLVM / WebKit / etc. styles
- creating custom formatter styles
- GUI for editing custom styles
- almost all options supported
- supports exporting / importing
- supported languages:
- C / C++
About the style edit dialog...
clang-format has a lot of style options. The main problem is that these options are all stored in one (well,
technically two) C
struct. There is no interface for getting a list of all supported options with some
metadata (name, description, data type, etc.), which would make generating a GUI easy. Additionally, this
struct changes with different clang/LLVM versions. This makes hardcoding the GUI impossible without template
metaprogramming and/or excessive use of
#if blocks. Naturally, the plugin would also have to be constantly
updated with new LLVM versions.
That's why I have decided to write a small (~1500 lines of code) code generator for generating the GUI and
mapping it to the clang-format config struct. The generator uses the clang C API, that is also used for the
KDevelop C++ background parser (so no new dependencies and no fragile parsing of C++ code with
As a result, all options (except for those with the type
vector<CustomStruct>) that the local LibFormat
library supports can be set in the GUI.
