问题 I have a reactive form that on cancel has to set again the initial form values into the formGroup. import { Map } from "immutable"; @Input() data: any; public ngOnInit() { if (this.data && this.data.controls) { this.group = this.fb.group({ isActive: [this.data.isActive], items: this.fb.array(this.buildFormArray(this.data.controlPerformers)), }); // Deep copy of the formGroup with ImmutableJs this.originalFormData = Map(this.group).toJS(); } } public buildFormArray(controllers:

问题 Why does os.system('command') from my python interpreter not have the same output as command from the terminal? Question explained quickly : I have echo $CONFPATH /home/claramart/Datamart/Parameter but os.system('echo $CONFPATH') 0 Why is that? Details : I want to get my environment $CONFPATH. I'm using python3.5 and ubuntu16.04.2. I can do this from command line : echo $CONFPATH /home/claramart/Datamart/Parameter This is the answer I want. Executing it as a python command from command line

问题 I've got some C code from a 3rd party vendor (for an embedded platform) that uses global variables (for speed & space optimizations). I'm documenting the code, converting to Doxygen format. How do I put a note in the function documentation that the function requires on global variables and functions? Doxygen has special commands for annotating parameters and return values as describe here: Doxygen Special Commands. I did not see any commands for global variables. Example C code: extern

问题 I am working on a custom theme and on one of the pages i need to style the posts pages as follows: http://gyazo.com/e1f7cfc03c7ba3981188077afcdf0314 The grey box is an image and the red box is content. I need to use perhaps an odd/even Li/Ul pseudo class/selector but i have no idea how to do it. Could anyone offer me a way to start it up? I was thinking of using the Odd/Even pseudo class on UL to change the divs names however i can't think how to do it or where to start. Thanks! Edit: I am

问题 I'm trying to use git2r package (version 0.21.0). I always use ssh connexions in my projects (GitHub and GitLab hosted): I can do git pull/push with both RStudio IDE and command line. I have a standard Ubuntu Xenial configuration; my keys are stored in ~/.ssh with standard names, my ssh-agent is running, and keys were added to ssh-agent . My problem is how to use the git2r package to push with ssh ? Here's what I do with a very basic workflow (work on master , remote name is origin ): library
