使用org-mode管理emacs中的firefox选项卡

Question

我最近找到了一种在emacs中管理firefox选项卡的方法.这听起来有点疯狂.我使用树形样式选项卡(firefox addon),Moz Repl,emacs,org-mode来完成它.

对于10-15个标签,我的计划工作正常.但是20多个标签,我的firefox随机挂起.也许javascript堆栈溢出或其他什么？我不知道我的代码有什么问题.我在这里发布了最重要的代码.有人帮我发现了一些错误？

它是下面的基本firefox chrome代码,你可以在没有emacs和MozPepl的Firefox中运行它.

我使用树形样式选项卡api来获取选项卡并将每个选项卡设置为cetain级别.输出将在带有org-mode的emacs中使用.tree style tabs api:http://piro.sakura.ne.jp/xul/_treestyletab.html.en#api

守则可以以多种方式运作.我推荐"工作区插件".复制我的代码,选择chrome上下文来运行它. https://addons.mozilla.org/en-US/firefox/addon/workspace/

// two helper function to get title and url of tab
function getTitle(tab)
{ 
    var brower = gBrowser.getBrowserForTab(tab)
    var url = brower.currentURI.spec
    var title = brower.contentTitle
    return title
}
function getUrl(tab)
{ 
    var brower = gBrowser.getBrowserForTab(tab)
    var url = brower.currentURI.spec
    var title = brower.contentTitle
    return ":PROPERTIES:\n:URL:"+url+"\n:END:\n"
}

var L = gBrowser.tabContainer.childNodes.length //firefox tabs length
var str = "" //global string for output

//parse tabs. If tab has child, parse it. It tab has no child, just output.
for(i = 0; i < L; i++){
    level = "*"
    tab = gBrowser.tabContainer.childNodes[i]
    if ('TreeStyleTabService' in window){
    if(TreeStyleTabService.hasChildTabs(tab))
    {
      str = [str, level, " [+] ",  getTitle(tab), "\n", getUrl(tab)].join("") //output title and url. level used in org-mode
      treeparse(TreeStyleTabService.getChildTabs(tab), "**") //if a tab has child tabs. parse it and level up
    }   
str = [str, level, " ",  getTitle(tab), "\n", getUrl(tab)].join("")
}

function treeparse(tablist,level) //parse a list of tabs. If tab has not a child, output. If it has childs, parse again
{
    for(i=0 ; i < tablist.length;i++) {
    tab = tablist[i]
    if ('TreeStyleTabService' in window){
        if(TreeStyleTabService.hasChildTabs(tab))
        {
        str = [str, level, " [+] ",  getTitle(tab), "\n", getUrl(tab)].join("")
        newlevel = level + "*"
        treeparse(TreeStyleTabService.getChildTabs(tab),newlevel)       
        }
        } }
    str = [str, level, " ",  getTitle(tab), "\n", getUrl(tab)].join("")
    }
}

alert(str) //alert to view result. You can also write the result into a file.

我不确定具体是什么导致了这个问题，因为我无法重现它，但我发现这段代码存在很多问题。我不记得 MozRepl 是如何工作的，但是这个改进的代码应该会给你一个很好的组织模式友好的选项卡输出。我希望这对您或任何偶然发现此线程的人有所帮助。

var bullet = "*"; // Org-mode bullet

// two helper function to get title and url of tab
function getTitle(tab) { 
    var brower = gBrowser.getBrowserForTab(tab);
    var url = brower.currentURI.spec;
    var title = brower.contentTitle;
    return title;
}

function getUrl(tab) { 
    var brower = gBrowser.getBrowserForTab(tab);
    var url = brower.currentURI.spec;
    var title = brower.contentTitle;
    return ":PROPERTIES:\n:URL:"+url+"\n:END:\n";
}

// NOTE: we factor these string-generation functions out,
// to make things a bit more clear
function makeParentNodeOutput(tab, level) {
    return (Array(level+1).join(bullet) +
        " [+] " +
        getTitle(tab) +
        "\n" +
        getUrl(tab));
}

function makeLeafNodeOutput(tab, level) {
    return (Array(level+1).join(bullet) +
        " " +
        getTitle(tab) +
        "\n" +
        getUrl(tab));
}

// NOTE: we only need to handle parsing a collection of tabs
// in once place, and we have a function for it here.
function parseTabCollection(tabs, level) {
    var currentTab;
    var outputString = "";
    for(var i = 0; i < tabs.length; i++){
        currentTab = tabs[i];

        // For a parent node, we output the node and its children
        if(TreeStyleTabService.hasChildTabs(currentTab)){
            outputString += makeParentNodeOutput(currentTab, level);
            outputString += parseTabCollection(
                TreeStyleTabService.getChildTabs(currentTab),
                level + 1
            );
        } else {
            outputString += makeLeafNodeOutput(currentTab, level);
        }
    }
    return outputString;
}

if ('TreeStyleTabService' in window){
    //NOTE: Start with the rootTabs only. The old version started with
    // *all* tabs, which isn't what we want
    var orgModeOutput = parseTabCollection(TreeStyleTabService.rootTabs, 1);
    alert(orgModeOutput);
}

我希望这会有所帮助。
