bootstrapping

问题 I understand how a language can bootstrap itself, but I haven't been able to find much reference on why you should consider bootstrapping. The intuitive answer is that the language you're writing offers utilities that are not found in the "base" language of the compiler, and the language's features are relatively well-suited for a compiler. For instance, it would make sense to bootstrap a C++ compiler -- it could potentially be much easier to maintain the compiler when OOP is properly used,

问题 I am using dotNetInstaller as a bootstrapper and I need to detect if SQL Server 2008 or above is installed as a prerequisite. Currently I am using this registry to detect the installation: HKLM\SOFTWARE\Microsoft\Microsoft SQL Server 2008 Redist\SharedManagementObjects\1033\CurrentVersion\Version If the value of Version is 10.0.0 or higher it detects it as installed. We tried the installation package on 10 machines here (Windows XP SP3 & Windows 7) and the prerequisite worked fine. We are

问题 I have the included grails script that I found in some random place on the internet and it works pretty well for firing up scripts in a bootstrapped grails env. The only thing it doesn't seem to do is kick off my conf/*Bootstrap.groovy scripts like when I do run-app. Is there another function like loadApp() and configureApp() that will do that for me? import org.codehaus.groovy.grails.support.PersistenceContextInterceptor Ant.property(environment: "env") grailsHome = Ant.antProject.properties

问题 I am trying to create an instance of a domain class inside a grails 2.3.6 script: def player = new Player(name:"Bob") player.save() But I keep getting an exception java.lang.NoClassDefFoundError: gaming/Player I've tried all the different bootstrapping tricks I've managed to find on the internet but they don't really change the result: I've tried importing: import gaming.Player I've tried loading the bootstrap script: includeTargets << grailsScript("_GrailsBootstrap") I've tried depending on

问题 Here is what I have tried so far. ctx.setAttribute("class", "glyphicon glyphicon-time"); but also; var icon = document.createElement("span"); icon.className ="glyphicon glyphicon-time"; this.appendChild(icon); 回答1: You can make use of the html2canvas.js. The following code may help you: HTML <span class="glyphicon glyphicon-align-left"></span> <canvas id="canvas" width="300" height="300"></canvas> JS html2canvas(document.querySelector('.glyphicon'), { onrendered: function(canvas) { var

问题 I have a panel data, i.e. t rows for each of n observations ( nxt ), such as data("Grunfeld", package="plm") head(Grunfeld) firm year inv value capital 1 1935 317.6 3078.5 2.8 1 1936 391.8 4661.7 52.6 1 1937 410.6 5387.1 156.9 2 1935 257.7 2792.2 209.2 2 1936 330.8 4313.2 203.4 2 1937 461.2 4643.9 207.2 I want to make block bootstrapping, i.e. I want resample with replacement, taking a firm [i] with all the years in which it is observed. For instance, if year=1935:1937 and firm 1 is randomly

问题 I'm pulling my hair out trying to figure this one out. I can't get the Bootstrap to work properly when outside of the Drupal dir. It works fine if I run this code in the Drupal dir, but up one level doesn't work. My Drupal path is /public_html/drupal/. The script I'm running is in /public_html. $user is not returning the logged in user. I've made sure it's not a cross-domain issue (i.e. www.domain.com vs. domain.com). chdir('/path/to/drupal'); include_once('./includes/bootstrap.inc'); drupal

问题 This question already has answers here : Closed 9 years ago . Possible Duplicates: How can a language's compiler be written in that language? implementing a compiler in “itself” I was looking at Rubinius, a Ruby implementation that compiles to bytecode using a compiler written in Ruby. I cannot get my head around this. How do you write a compiler for a language in the language itself? It seems like it would be just text without anything to compile it into an executable that could then compile

问题 I was going through the basics of angularJS about how it is manually bootstrapped. I came across different approach and found this approach to be best fitted. angular.element(document).ready(function(){ angular.bootstrap(document,['myapp']) }) Moving further, I came across this another way which breaks it to basics. I have commented the code as per my understanding but can someone please explain to me in more details about how things are working under the hood. window.onload = function (){
