variables

问题 In my project makefile, there is a variable named "- -command-variables- -". I could guess its meaning from the context, but I want to know more about "- -command-variables- -". No result from google and GNU make manual. Here is my test makefile, all: $(warning $(-*-command-variables-*-)) #$(warning $(.VARIABLES)) #$(foreach v, $(.VARIABLES), $(info $v===>$($v))) When I type make test=Makefile , it prints out: Makefile:2: test=Makefile make: `all' is up to date. I found this variables is in

问题 I'm trying build an sort of property set in ksh. Thought the easiest way to do so was using arrays but the syntax is killing me. What I want is to Build an arbitrary sized array in a config file with a name and a property. Iterate for each item in that list and get that property. I theory what I wish I could do is something like MONITORINGSYS={ SYS1={NAME="GENERATOR" MONITORFUNC="getGeneratorStatus"} SYS2={NAME="COOLER" MONITORFUNC="getCoolerStatus"} } Then later on, be able to do something

Improve this question I am teaching C programming and I am quite strict regarding variable declaration. As we use the C11 standard and knowing that the students would later use other programming language, I teach this rule: Any declared symbol should have its scope as narrow

问题 I am running a Node+Express API that is working quite well, the only problem I have is when returning a complex query as a response, the variable to which I set the response to is not getting reset between requests. It duplicates replies to the client such as replying 1, 2, 3 then the next reply replies 1, 2, 3, 1, 2, 3. So basically, it's concatenating data and not setting the allPosts variable to null again. Here is my code: var allPosts = []; chirprdb.allPosts = (userData) => { return new

问题 I'm new to Tensorflow. I worked in Caffe previously. I'm trying to implement http://cvlab.cse.msu.edu/pdfs/Tai_Yang_Liu_CVPR2017.pdf in Tensorflow. I'm having trouble with variables in Tensorflow, despite having them initialized. I tried using tf.get_variable instead of tf.Variable, but this didn't work. And setting initializer=tf.contrib.layers.xavier_initializer() did nothing. My code: import tensorflow as tf import sys, os import numpy as np global xseed def get_model(inp, train): #create

问题 I have the following variables: [string]$eth_netmask = "ext_netmask" [string]$ext_netmask = "255.255.252.0" $($eth_netmask) is returning ext_netmask . I was expecting 255.255.252.0 What am I doing wrong? Thanks for the help in advance! 回答1: The command $eth_netmask returns the value of the variable named eth_netmask. The expression $(something) has nothing to do with variables, but instead evaluates the contents of the parentheses before evaluating the rest of the statement. That means that

问题 i've implemented a global variable but i dont really know how to access it. The examples i have found are a bit confusing. models.py ... # Categorys of Post Model class Category(models.Model): title = models.CharField(max_length=255, verbose_name="Title") class Meta: verbose_name = "Category" verbose_name_plural = "Categories" ordering = ['title'] def __str__(self): return self.title #Post Model class Post(models.Model): author = models.ForeignKey('auth.User', on_delete=models.CASCADE) title

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: Declaring Multiple Variables in JavaScript I was wondering whether there is a difference in listing variables in JavaScript (and JS libraries). Example : var $this = $(this), $body = $("body"), $main-wrap = $("body > section.wrapper"); OR var $this = $(this); var $body = $("body"); var $main-wrap = $("body > section.wrapper"); I always thought that the difference only lies in notation. The first example is
