path

问题 I guess I need to add some explanation, that I want to ask this question, because too short question doesn't quality standards... funny... So, here is the question: How I can get the 'y' coordinate of the point on svg path at a specific 'x' coordinate? 回答1: Well this is not straightforward, because a path could have multiple points with the specified x coordinate. There is no built-in function in the SVG DOM to do this. One solution is to step along the path segments and do the maths yourself

问题 @app.route('/view', methods=['GET', 'POST']) def view_notifications(): posts = get_notifications() return render_template("frontend/src/view_notifications.html", posts=posts) So in my project/backend/src/app.py there's this code.

问题 What should I write on ${PATH}? First, I thought it was the directory where the script I was working on. Second I thought it was the directory where the make or something is. But both were wrong. 回答1: ${PATH} is the value of the path variable already present on your computer. PATH="${RTOOLS40_HOME}\usr\bin;${PATH}" is adding ${RTOOLS40_HOME}\usr\bin to the existing path so that RTOOLS can be found when needed. If RTOOLS installation went correctly, RTOOLS40_HOME environment variable should
