Need help with setTextFormat (AS3) - actionscript-3

I'm trying to make an rss reader with Flash CS5.5. It's almost finished but i couldn't style news titles. The problem is some parts of a textfield needs to be bold and colored. Here's my code:
var num:int = 0;
var tempText:String;
var titleStr:String;
var timeStr:String;
var descriptionStr: String;
function rssLoaded(evt:Event):void {
rssXML = XML(rssLoader.data);
// trace(rssXML);
num = 0;
for (var rssTitle:String in rssXML.channel.item) {
// Set title
tempText = rssXML.channel.item[rssTitle].title;
tempText = tempText.slice(6);
titleStr = tempText + "\r\n";
// Set description
tempText = rssXML.channel.item[num].description;
// Detect if beginning with tags
if ((tempText.charCodeAt(0) == 60) && (tempText.charCodeAt(1) == 73)) {
tempText = tempText.slice(tempText.search("/>") + 2, tempText.search("<img"));
} else {
tempText = tempText.slice(0, 140);
}
// Detect if still contains tags
if ((tempText.indexOf("<") != -1) || (tempText.indexOf(">") != -1)) {
num++;
continue;
}
// Detect if beginning with space
for (var num2:int=0; tempText.charCodeAt(0) == 32 || tempText.charCodeAt(0) == 160; num2++) {
tempText = tempText.slice(1);
}
descriptionStr = tempText + "...\r\n\r\n";
main_txt.appendText(titleStr);
main_txt.setTextFormat(title_tf, main_txt.text.length - titleStr.length, titleStr.length-2);
main_txt.appendText(descriptionStr);
num++;
}
}
var title_tf:TextFormat=new TextFormat();
title_tf.bold=true;
When I test the code, I'm seeing that only the first line is bold, while all titles needs to be bold. Sorry for my English.
Sincerely

It would be much simpler to style the text using the TextField.htmlText property:
title_tf.htmlText = "<b>" + titleTextString + "</b><br/>" + bodyTextString;
This approach would also allow you to use CSS like this:
title_tf.styleSheet = myImportedStyleSheet;
title_tf.htmlText = "<span class='titleClass'>" + titleTextString + "</span><br/><span class='bodyClass'>" + bodyTextString + "</span>";

Problem with executing google app script (google slides) after renaming presentation and script

I'm quite new to programming and using google apps scripts.
I wrote script that splits selected text in text box (google slides) in different text boxes (each line of initial textbox is a separated textbox). Code was just a modification of examples from developers.google.com.
function SelectedTextGrabber() {
var selection = SlidesApp.getActivePresentation().getSelection();
var selectionType = selection.getSelectionType();
var currentPage;
switch (selectionType) {
case SlidesApp.SelectionType.NONE:
Logger.log('Nothing selected');
break;
...
case SlidesApp.SelectionType.TEXT:
var tableCellRange = selection.getTableCellRange();
if (tableCellRange != null) {
var tableCell = tableCellRange.getTableCells()[0];
Logger.log('Selected text is in a table at row ' +
tableCell.getRowIndex() + ', column ' +
tableCell.getColumnIndex());
}
var textRange = selection.getTextRange();
if (textRange.getStartIndex() == textRange.getEndIndex()) {
Logger.log('Text cursor position: ' + textRange.getStartIndex());
} else {
Logger.log('Selection is a text range from: ' + textRange.getStartIndex() + ' to: ' +
textRange.getEndIndex() + ' is selected');
var s1 = textRange.asString();
var s2 = '';
var s3 = [];
for (var i = 0; i < s1.length; i++){
if (s1[i] === '\n' || i === s1.length -1) {
s3.push(s2);
s2='';
} else {
s2 += s1[i];
}
}
// textbox parameteres
var h4 = 0;
var left = 10;
var top = 10;
var textsize = 12;
var standnum = 37;
var width = 2 * textsize + (textsize - textsize % 2) / 2 * standnum;
Logger.log(width);
var slide = SlidesApp.getActivePresentation().getSlides()[1];
for (var i = 0; i < s3.length; i++){
//анализ размера текстового блока
var s4 = s3[i].length;
if (s4 <= standnum) {
h4 = textsize * 2;
} else {
h4 = textsize * 2 + (s4 - s4 % standnum) / standnum * textsize;
}
var shape = slide.insertShape(SlidesApp.ShapeType.TEXT_BOX, left, top, width, h4);
var textRange = shape.getText();
textRange.setText(s3[i]);
textRange.getTextStyle().setFontSize(textsize);
top += h4;
if (top > 370) {
top = 10;
left += width;
}
}
}
break;
case SlidesApp.SelectionType.TABLE_CELL:
var tableCells = selection.getTableCellRange().getTableCells();
var table = tableCells[0].getParentTable();
Logger.log('There are ' + tableCells.length + ' table cells selected.');
break;
case SlidesApp.SelectionType.PAGE:
var pages = selection.getPageRange().getPages();
Logger.log('There are ' + pages.length + ' pages selected.');
break;
default:
break;
}
}
It worked just fine, but when I renamed script and presentation, I get the TypeError: Cannot call method "getSelectionType" of null. (line 4, file "Code").
After 30 minutes of waiting this script started working again without errors.
I thought it may happen because it takes time to make some changes in google servers.
But when I modified initial text in text box to be splitted the script gave me the same result as I didn't change initial text (the result is separated lines in textboxes but for initial text).
Do u have any idea what should I do to fix it?

How to prevent my github page from making post title 'title-cased'

I have created a github page and have chosen one of proposed Jekyll themes called minima. To add a post I have created a file called 2018-11-16-My-first-post-on-github.md. However, the post title displayed is a text converted to title case: My First Post On Github, so every first letter in each word is made upper case. How can I prevent that? Is this theme-dependent?
exports.toTitleCase = function(str){
var smallWords = /^(a|an|and|as|at|but|by|en|for|if|in|nor|of|on|or|per|the|to|vs?\.?|via)$/i;
return (str+'').replace(/[A-Za-z0-9\u00C0-\u00FF]+[^\s-]*/g, function(match, index, title){
if (index > 0 && index + match.length !== title.length &&
match.search(smallWords) > -1 && title.charAt(index - 2) !== ":" &&
(title.charAt(index + match.length) !== '-' || title.charAt(index - 1) === '-') &&
title.charAt(index - 1).search(/[^\s-]/) < 0) {
return match.toLowerCase();
}
if (match === 'tus') {
return match;
}
if (match.substr(1).search(/[A-Z]|\../) > -1) {
return match;
}
// Avoid uppercasing 'mod_deflate', apt-file - kvz
if (match.match(/.[\_\-\/\d]./)) {
return match;
}
// Avoid uppercasing '`frame`', '/sftp/import' - kvz
if (match.match(/(^[`\/]|[`]$)/)) {
return match;
}
// Avoid uppercasing: 'tmpfs' or anything that doesn't have a vowel - kvz
if (!match.match(/[aeiou]/)) {
return match;
}
return match.charAt(0).toUpperCase() + match.substr(1);
});
};
exports.newPost = function (content, opts, cb){
var self = this;
var matches = [];
var oldTitle = '';
var newTitle = '';
var oldLine = '';
var heading = '';
var newLine = '';
var changes = [];
var words = [];
var frontMatter = content.split('---')[1];
if (frontMatter) {
matches = frontMatter.match(/^(title\s*:\s*)\"?(.+?)\"?[\ \t]*$/im);
oldTitle = matches[2];
newTitle = self.toTitleCase(oldTitle).trim();
oldLine = matches[0];
newLine = matches[1] + '"' + newTitle + '"';
if (oldLine !== newLine) {
changes.push({oldTitle: oldTitle, newTitle: newTitle});
content = content.replace(oldLine, newLine);
}
}
if (opts.body === true) {
matches = content.match(/^\#{1,6} ([a-zA-Z0-9\-\;\!\?\%\&\;\:\.\/\(\)\ ]+)$/mg)
for (var i in matches) {
words = matches[i].split(' ')
heading = words.shift();
oldTitle = words.join(' ');
newTitle = self.toTitleCase(oldTitle).trim();
oldLine = heading + ' ' + oldTitle;
newLine = heading + ' ' + newTitle;
if (oldLine !== newLine) {
changes.push({oldTitle: oldTitle, newTitle: newTitle});
content = content.replace(oldLine, newLine);
}
}
}
if (changes.length === 0) {
content = null;
}
return cb(null, content, changes);
};
Jekyll automatically converts your post title to uppercase upon import. You can fix this by using a plugin, or by using a YAML file or Front matter to specify your title value directly.

How I can get the textwrap image in google doc

Due to this answer now I can make copy of elements with images right, but I spotted one more thing - if image inserted as 'in text' - then copying is done well. But when I make it 'text wrap', I can't find this element at all!
Here is the code of test:
function test_show_all_structure_of_doc() {
var final = 'final';
var doc = get_doc(working_directory, final);
var body = doc.getBody();
var elements = body.getNumChildren();
for( var i=0;i<elements;i++) {
var element = body.getChild(i).copy();
var type = element.getType();
if( type == DocumentApp.ElementType.PARAGRAPH ){
Logger.log('paragraph' + i);
var children = element.getNumChildren();
if (children >0) {
for (var j=0;j<children;j++) {
var subelement = element.getChild(j).copy();
var subtype = subelement.getType();
Logger.log('subelement ' + j + ":" + subtype);
if (subtype == DocumentApp.ElementType.TEXT) Logger.log(subelement.getText());
}
}
}
else if( type == DocumentApp.ElementType.TABLE ){
Logger.log('table');}
else if( type == DocumentApp.ElementType.LIST_ITEM ){
Logger.log('list item');}
else if( type == DocumentApp.ElementType.INLINE_IMAGE ){
Logger.log('inline image');}
else {
throw new Error("check what to do with this type of element : "+ type);
}
}
}
so where I can find textwrap image? Or it is impossible for now?
This is not possible using Google Apps Script (for now) and is the object of an enhancement request for more than 2 years now.
In the mean time, only inline image is supported.

Google Apps Script: Server encountered an error. Try again later

I am stuck.. Error is thrown # Line 63 and sometimes at line 50. Both using the appendTableRow() method. I can't find anything wrong.
row3.appendTableCell(entryDesc)

I found a solution, it appears that: body.appendTableCell(); doesn't handle line breaks "\n". When the script was importing a multi-line event description from the calendar I would get a "server error" message. Adding split('\n') to the description row solved the problem. This worked: body.appendTableCell(data).split("\n");
Finished code:
var entryDesc = (events[i].getDescription().length > 1) ? events[i].getDescription() : "";
if (entryDesc) {
var row3 = entriesTable.appendTableRow();
row3.appendTableCell("");
row3.appendTableCell(entryDesc.split("\n"))
.setAttributes(entryDescriptionStyle);
}
I don't have a complete answer but I thought it might be interesting in the mean time to show a version that works without the event description.
I changed the calculation of total time that didn't work either.
Code can be tested on any default calendar using test function.
function test(){

var doc = DocumentApp.getActiveDocument();
var dateStart = new Date('January 1, 2014');
var dateFinish = new Date('April 1, 2014')

I'm wondering if there is something like 9-patch in Android, but for web development?
Disclosure: I have no idea about web development at all, but I was curious to know if it exists. And a simple web search with the term 9-patch didn't bring up any related results, so I figured it has either another term or it doesn't exist or is not used widely enough.
Anyone knows?
Yes. It is used for border-image in CSS 3:
http://www.css3.info/preview/border-image/
http://www.w3.org/TR/css3-background/#border-images
If you're still interested I created a Javascript file that uses canvas to create real nine patch image support for the web. The open source project can be found here:
https://github.com/chrislondon/9-Patch-Image-for-Websites
Well, I took the trouble to correct deserts errors I found in the link above.
Knowing NinePath android is a useful tool adding dynamic painting and recognition of padding (which was missing in the previous pluying). I could add one few scripts for complete functionality.
Replace the following code in the library path9.js!
function NinePatchGetStyle(element, style)
{
if (window.getComputedStyle)
{
var computedStyle = window.getComputedStyle(element, "");
if (computedStyle === null)
return "";
return computedStyle.getPropertyValue(style);
}
else if (element.currentStyle)
{
return element.currentStyle[style];
}
else
{
return "";
}
}
// Cross browser function to find valid property
function NinePatchGetSupportedProp(propArray)
{
var root = document.documentElement; //reference root element of document
for (var i = 0; i < propArray.length; i++)
{
// loop through possible properties
if (typeof root.style[propArray[i]] === "string")
{
//if the property value is a string (versus undefined)
return propArray[i]; // return that string
}
}
return false;

The usage is the following:
var elemDom = document.getElementById("idDiv");
var background = "border.9.png";
if (background.match(/\.9\.(png|gif)/i)) // Es nine path?
{
elemDom.style.backgroundRepeat = "no-repeat";
elemDom.style.backgroundPosition = "-1000px -1000px";
elemDom.style.backgroundImage = "url('"+background+"')";
var ninePatch = new NinePatch(elemDom,function()
{
elemDom.style.paddingLeft = ninePatch.padding.left;
elemDom.style.paddingTop = ninePatch.padding.top;
elemDom.style.paddingRight = ninePatch.padding.right;
elemDom.style.paddingBottom = ninePatch.padding.bottom;
});

I forked https://github.com/chrislondon/9-Patch-Image-for-Websites and fixed the bugs based on the above comments. Now the 9-Patch javascript works well. Please check out https://github.com/blackmonkey/jQuery-9-Patch
