问题 I get a list of file paths from the backend, it represents a folder structure and looks like this: paths = ["path/to/file1.doc", "path/to/file2.doc", "foo/bar.doc] The lengths of the paths are arbitrary. In order to use a file tree component (angular2-tree-component) I need to transform this data into the following format: nodes = [ { "name": "path", "children": [ { "name": "to", "children": [ {"name": "file1.doc"}, {"name": "file2.doc"} ] } ] }, { "name": "foo", "children": [ {"name": "bar

问题 I'm self-teaching myself vanilla JS and hope to get really good with it. I've been racking my brain over this for several days. I'm trying to use template literals to display the properties of objects that are in an array. Those objects are portfolio projects. In each object, I have a property that is an array of icon images. I'm able to get everything rendered on the page except for all of the icon images. I can only get 1 icon image to display in my div with the class="skills-used". Can

问题 Through /proc file system , it's probable to read memory mappings with /proc/PID_PROCESS/maps , but is there any native APIs that dedicated for this function in C/C++ ? i.e to find out memory address that are writable and readable for process with PID 9322: %> awk -F "-| " '$3 ~ /rw/ { print $1 " " $2}' /proc/9322/maps 0804e000 0804f000 085ed000 0860e000 b7707000 b7708000 b7864000 b7865000 b7865000 b7868000 b7897000 b7898000 b78b6000 b78b7000 bfd2e000 bfd50000 And those address are passed

问题 Is it possible with MapStruct 1.2 to map a source property with a specific value to a specific different value in the target? I think about something like this: public abstract class JiraKpmMapper { @Mappings({ @Mapping(source = "mySource.propA", target = "myTarget.propX") }) @ValueMappings({ @ValueMapping(source = "ABC", target = "XYZ"), @ValueMapping(source = "123", target = "789") }) public abstract MyTarget source2Target(final MySource mySource); } So that when MapStruct sees during the

问题 I have a function which triggers children checkboxes once main checkbox is checked, and all these checkboxes are mapped from JSON.
