| # ImGuiColorTextEdit |
| Syntax highlighting text editor for ImGui |
| |
|  |
| |
| Demo project: https://github.com/BalazsJako/ColorTextEditorDemo |
| |
| This started as my attempt to write a relatively simple widget which provides source code editing functionality with basic syntax highlighting. Now there are other contributors who provide valuable additions. |
| |
| While it relies on Omar Cornut's https://github.com/ocornut/imgui, it does not follow the "pure" one widget - one function approach. Since the editor has to maintain a relatively complex and large internal state, it did not seem to be practical to try and enforce fully immediate mode. |
| |
| The code is (still) work in progress, please report if you find any issues. |
| |
| # Main features |
| - approximates typical code editor look and feel (essential mouse/keyboard commands work - I mean, the commands _I_ normally use :)) |
| - undo/redo support |
| - extensible, multiple language syntax support |
| - identifier declarations: a small piece of text associated with an identifier. The editor displays it in a tooltip when the mouse cursor is hovered over the identifier |
| - error markers: the user can specify a list of error messages together the line of occurence, the editor will highligh the lines with red backround and display error message in a tooltip when the mouse cursor is hovered over the line |
| - supports large files: there is no explicit limit set on file size or number of lines, performance is not affected when large files are loaded (except syntax coloring, see below) |
| - color palette support: you can switch between different color palettes, or even define your own |
| - supports both fixed and variable-width fonts |
| |
| # Known issues |
| - syntax highligthing of most languages - except C/C++ - is based on std::regex, which is diasppointingly slow. Because of that, the highlighting process is amortized between multiple frames. C/C++ has a hand-written tokenizer which is much faster. |
| - 8 bit character only, no Unicode or Utf support |
| - no find/replace support |
| |
| Don't forget to post your screenshots if you use this little piece of software in order to keep me us motivated. :) |
