使用 org-mode 管理 emacs 中的 Firefox 标签

Manage firefox tabs in emacs with org-mode

本文关键字：Firefox 标签 中的 emacs org-mode 管理 使用      更新时间：2023-09-26

我最近找到了一种在emacs中管理Firefox标签的方法。这听起来有点疯狂。我使用树样式选项卡（Firefox addon），Moz Repl，emacs，org-mode来做到这一点。

对于 10-15 个选项卡，我的计划运行良好。但是 20+ 标签，我的火狐随机挂起。也许是javascript堆栈溢出或其他什么？我不知道我的代码出了什么问题。我在这里发布最多的导入代码。有人帮我找到一些错误？

这是下面的一个基本的Firefox chrome代码，你可以在Firefox中运行它，而无需emacs和MozPepl。

我使用树样式选项卡 api 来获取选项卡并将每个选项卡设置为cetain级别。 输出将在具有 org-mode 的 emacs 中使用。树样式选项卡 API：http://piro.sakura.ne.jp/xul/_treestyletab.html.en#api

该代码可以通过多种方式运行。我推荐"工作区插件"。复制"我的代码"，选择"镶边上下文"以运行它。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问题，因为我无法重现它，但我看到这段代码有很多问题。我不记得 MozRepl 是如何工作的，但这个改进的代码应该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);
}

我希望这在某种程度上有所帮助。
