qt-creator: make stdout work in application-output-view

I really do love qt-creator and it is my IDE of choice for c++-development. But it has here and there some flaws....beside the fact that there are not tabs to represent the opened files, one strange thing is that outputs to stdout get are not visibile immediately. I&

CMake Error: CMake can not determine linker language for target: [XYZ]

Just stumpled over a strange problem using CMake. A usually straight forward setup adding a 2nd executable lead to an error like this: -- Configuring done CMake Error: CMake can not determine linker language for target: Tests -- Generating done This might be related to me now using cmake 3.

building qt-creator from source

Since qt-creator(4.11/4.12) integrated support for cmake's source_groups, headers and sources are split in two separate folders. 'Header-Files','Source-Files' which is a bit annoying (not so annoying as the initial lack of subfolders...). Because of that I downgraded a couple

cmake,emscripten and c++17

Trying to compile my c++17 based project (using entt) makes problems with using my urho3d-docker-web-image that uses emscripten for compilation to web. emcc (Emscripten gcc/clang-like replacement) 1.39.8 ((unknown revision)) Using (I'm mainly using gcc for compilation, android uses clang afaik?) target_compile_features(${PROJECT_

text(X)text or 'textX - lightweight xtext alternative for python'

Just stumpled over textX an xText inspired python-toolbox for creating DSLs. Super simple to use. I love xText but it can be really a pain in the ass here an there. Mainly because you (at least me) always forget about the internal concept and/or structure. Especially how to wire

git: get short hash of remote repo

Atm I'm maintaining my urho3d-minimal-new-project to use the latest version of urho3d in its docker-images. To make this a smoother 'one-click' process I want the new docker-images to have an additional flag like 'githash-$HASH' where the $HASH is the current short-version of the

Multimonitor-Setup mit 4k and HD

Ubuntu Mate: Since I have a 4k monitor I want to get both monitors to be scaled accordingly. I had to increase the dpi on the 4k which resulted in too big fonts on the HD-Monitor. Now I found a way to set this up right base on one forum-entry

rapidjson: iterate over object and array

// get an object auto groups = doc["groups"].GetObject(); // iterate over key-value-pairs ( group.name and group.value ) for (auto const& group : groups){ cout << "group:" << group.name.GetString() << endl; // the value is an array. The call to iterate over the array

GGJ '20 : Preparations

After I was ill last year I decided to attend headup's global game jam again. Perfect that it is located in my city and I can use it to kickstart me into Urho3D. Well,... I'm building on getting a good blender-addon for this for quite a

Blender-Addons: Get Nodetree of current node_editor panel

If you want to access data from the selected nodetree inside a node_editor panel: class UrhoExportNodetreePanel(bpy.types.Panel): bl_space_type = 'NODE_EDITOR' bl_region_type = 'UI' bl_label = "Urho3d-Nodetree" bl_category = "Urho3D" @classmethod def poll(cls, context): return True

docker: get rid of images and containers

I moved the blabbering behind the important stuff: how to get rid of the docker images/containers docker system prune # dangling containers docker system prune -a # dangling,stopped containers and all unused images docker rmi $(docker images -a -q) # all images docker rm $(docker ps -a -f status=exited -q)

CMake: glob_recurse with symbolic linked folders

If using CMake's file glob_recurse for catching source-file and you want this to also follow symbolic-links, just add the 'FOLLOW_SYMLINKS'-keyword: Like this: file( GLOB_RECURSE SOURCE_FILES FOLLOW_SYMLINKS src/*.cpp src/*.h ) Have look here: cmake file-docs And a bit related. In
