Eclipse CDT
for this to work reliably though, you still need to build using slow -j1 -w builds, so that make outputs non-interleaved "entering"/"leaving" lines.
... it also used to be necessary to add the following two lines to your mozconfig to make the compiler output errors all on a single line, but that may not be needed anymore: export cflags="-fmessage-length=0" export cppflags="-fmessage-length=0" debugging to create a debug configuration, open the project properties window, and select "run/debug settings" on the left.
... this "parse once" strategy can also cause "unresolved inclusion" errors in headers if the first time eclipse sees the header is while indexing a file for which it doesn't have any build output parser data.

mach
if you don't use mach, you have to find another solution for the following problems: discovering what commands or make targets are available (mach exposes everything through mach help while inside "mozilla-central" , else you'll just get a cryptic error message) making more sense out of command output (mach offers terminal colorization and structured logging) getting productive tools in the hands of others (mach "advertises" tools to people through mach help (unless it actually just gives you a cryptic error message) - in the former case, people don't need to discover your tool from a blog post, wiki page, or word of mouth).

Handling text — strings in JavaScript - Learn web development
so, taking a simple example: let song = 'fight the youth'; would be turned into a template literal like so: song = `fight the youth`; if we want to concatenate strings, or include expression results inside them, traditional strings can be fiddly to write: let score = 9; let highestscore = 10; let output = 'i like the song "' + song + '".
... i gave it a score of ' + (score/highestscore * 100) + '%.'; template literals simplify this enormously: output = `i like the song "${ song }".
... another point to note is that if you want to split a traditional string over multiple lines, you need to include a newline character, \n: output = 'i like the song "' + song + '".\ni gave it a score of ' + (score/highestscore * 100) + '%.'; template literals respect the line breaks in the source code, so newline characters are no longer needed.
... this would achieve the same result: output = `i like the song "${ song }".

Server-side web frameworks - Learn web development
they provide tools and libraries that simplify common web development tasks, including routing urls to appropriate handlers, interacting with databases, supporting sessions and user authorization, formatting output (e.g.
...every "view" function (a request handler) receives an httprequest object containing request information, and is required to return an httpresponse object with the formatted output (in this case a string).
... # return httpresponse return httpresponse('output string to return') route requests to the appropriate handler most sites will provide a number of different resources, accessible through distinct urls.
...these allow you to specify the structure of an output document, using placeholders for data that will be added when a page is generated.

Getting started with Svelte - Learn web development
on the left side of the screen you'll see the code of your components, and on the right you'll see the running output of your app.
... on the right side you have three tabs: the result tab shows your app output, and provides a console at the bottom.
... the js output tab lets you inspect the javascript code generated by svelte, and set compiler options.
... the css output tab shows the css generated by svelte.

Accessibility/LiveRegionDevGuide
current utterances should be allowed to finish but the 'rude' messages should be output as soon as possible.
...it was originally intended to give web developers a means to force a live region message to go to a separate output device.
...however, the channel property is also significant for single output applications that rely on speech output only.
... in this case, 'main' channel messages are queued according to the 'live' property and 'alert' channel messages bypass the queue and are output immediately.

Multiprocess on Windows
com metadata midl outputs two different types of metadata: "fast format strings" (also known as oicf) and (optionally, if a library statement is included in the idl) type libraries (also known as typelib).
...it also will output a file with the .tlb extension.
...if your interface outputs an array of interfaces, the interceptor would only wrap the first element in the array, because it cannot distinguish between scalars and arrays.
...this receives the com interface which you want to wrap as its first parameter, and outputs the wrapped object (with the same interface) as its second parameter.

Internationalized Domain Names (IDN) Support in Mozilla Browsers
the final step of the process is the affixing of the ace prefix to the output string from the nameprep/stringprep and punycode processing.
... since the punycode contains only ascii characters, it is possible that an output may, though unlikely, coincide with existing domain names.
... to avoid such a complication, rfc 3490 defines a special prefix "xn--" for the ace (punycode) output.
... as an example, an output string to be sent to a dns server for a japanese domain name, "http://ジェーピーニック.jp", will look like the following in ace form: http://xn--hckqz9bzb1cyrb.jp domain name registration after the technical standards were established by ietf, the last remaining issue was for domain name registrars to agree on an international guideline on the use of idn characters.

Client-side form validation - Learn web development
the constraint validation api most browsers support the constraint validation api, which consists of a set of methods and properties available on the following form element dom interfaces: htmlbuttonelement (represents a <button> element) htmlfieldsetelement (represents a <fieldset> element) htmlinputelement (represents an <input> element) htmloutputelement (represents an <output> element) htmlselectelement (represents a <select> element) htmltextareaelement (represents a <textarea> element) the constraint validation api makes the following properties available on the above elements.
...function addevent(element, event, callback) { let previouseventcallback = element["on"+event]; element["on"+event] = function (e) { const output = callback(e); // a callback that returns `false` stops the callback chain // and interrupts the execution of the event callback.
... if (output === false) return false; if (typeof previouseventcallback === 'function') { output = previouseventcallback(e); if(output === false) return false; } } }; // now we can rebuild our validation constraint // because we do not rely on css pseudo-class, we have to // explicitly set the valid/invalid class on our email field addevent(window, "load", function () { // here, we test if the field is empty (remember, the field is not required) // if it is not, we check if its content is a well-formed e-mail address.

...we then select all of them using document.queryselectorall(), then loop through each one, adding an onclick handler to each that makes it so that a random color is applied to each one when selected: const divs = document.queryselectorall('div'); for (let i = 0; i < divs.length; i++) { divs[i].onclick = function(e) { e.target.style.backgroundcolor = bgchange(); } } the output is as follows (try clicking around on it — have fun): most event handlers you'll encounter have a standard set of properties and functions (methods) available on the event object; see the event object reference for a full list.
...the output is as follows: note: for the full source code, see preventdefault-validation.html (also see it running live here.) event bubbling and capture the final subject to cover here is something that you won't come across often, but it can be a real pain if you don't understand it.

Control flow and error handling - JavaScript
for example: var x = 1; { var x = 2; } console.log(x); // outputs 2 this outputs 2 because the var x statement within the block is in the same scope as the var x statement before the block.
... (in c or java, the equivalent code would have outputted 1.) since ecmascript2015, the let and const variable declarations are block-scoped.
... // while f() executes, the `finally` block returns false, // which overwrites the `throw` inside the above `catch` console.log('caught outer "bogus"'); } // output // caught inner "bogus" // false nesting try...catch statements you can nest one or more try...catch statements.

Working with objects - JavaScript
// animal properties and method encapsulation var animal = { type: 'invertebrates', // default value of properties displaytype: function() { // method which will display type of animal console.log(this.type); } }; // create new animal type called animal1 var animal1 = object.create(animal); animal1.displaytype(); // output:invertebrates // create new animal type called fishes var fish = object.create(animal); fish.type = 'fishes'; fish.displaytype(); // output:fishes inheritance all objects in javascript inherit from at least one other object.
...delete myobj.a; console.log ('a' in myobj); // output: "false" you can also use delete to delete a global variable if the var keyword was not used to declare the variable: g = 17; delete g; comparing objects in javascript, objects are a reference type.
...me: 'apple'}; fruit == fruitbear; // return false fruit === fruitbear; // return false // two variables, a single object var fruit = {name: 'apple'}; var fruitbear = fruit; // assign fruit object reference to fruitbear // here fruit and fruitbear are pointing to same object fruit == fruitbear; // return true fruit === fruitbear; // return true fruit.name = 'grape'; console.log(fruitbear); // output: { name: "grape" }, instead of { name: "apple" } for more information about comparison operators, see comparison operators.

Array.prototype.reduce() - JavaScript
the reduce() method executes a reducer function (that you provide) on each element of the array, resulting in single output value.
... it is almost always safer to provide an initialvalue, because there can be up to four possible output types without initialvalue, as shown in the following example: let maxcallback = ( acc, cur ) => math.max( acc.x, cur.x ); let maxcallback2 = ( max, cur ) => math.max( max, cur ); // reduce without initialvalue [ { x: 2 }, { x: 22 }, { x: 42 } ].reduce( maxcallback ); // nan [ { x: 2 }, { x: 22 } ].reduce( maxcallback ); // 22 [ { x: 2 } ].reduce( maxcallback );...
...the code below will produce the same output as the code in the block above: [0, 1, 2, 3, 4].reduce( (accumulator, currentvalue, currentindex, array) => accumulator + currentvalue ) if you were to provide an initialvalue as the second argument to reduce(), the result would look like this: [0, 1, 2, 3, 4].reduce((accumulator, currentvalue, currentindex, array) => { return accumulator + currentvalue }, 10) callback iteratio...

...this includes exceptions thrown inside of the catch-block: (function() { try { try { throw new error('oops'); } catch (ex) { console.error('inner', ex.message); throw ex; } finally { console.log('finally'); return; } } catch (ex) { console.error('outer', ex.message); } })(); // output: // "inner" "oops" // "finally" the outer "oops" is not thrown because of the return in the finally-block.

JavaScript typed arrays - JavaScript
for example, given the code above, we can continue like this: let int16view = new int16array(buffer); for (let i = 0; i < int16view.length; i++) { console.log('entry ' + i + ': ' + int16view[i]); } here we create a 16-bit integer view that shares the same buffer as the existing 32-bit view and we output all the values in the buffer as 16-bit integers.
... now we get the output 0, 0, 2, 0, 4, 0, 6, 0.
...consider this: int16view[0] = 32; console.log('entry 0 in the 32-bit array is now ' + int32view[0]); the output from this is "entry 0 in the 32-bit array is now 32".

xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:namespace-alias> element is a rarely used device that maps a namespace in the stylesheet to a different namespace in the output tree.
...to prevent a normally xsl:-prefixed literal result element (which should simply be copied as-is to the result tree) from being misunderstood by the processor, it is assigned a temporary namespace which is appropriately re-converted back to the xslt namespace in the output tree.
... result-prefix specifies the desired namespace for the output tree.

Using the Mozilla JavaScript interface to XSL Transformations - XSLT: Extensible Stylesheet Language Transformations
transformtodocument xsltprocessor.transformtodocument() takes one argument, the source node to transform, and returns a new document with the results of the transformation: var newdocument = processor.transformtodocument(domtobetransformed); the resultant object depends on the output method of the stylesheet: html - htmldocument xml - xmldocument text - xmldocument with a single root element <transformiix:result> with the text as a child transformtofragment you can also use xsltprocessor.transformtofragment() which will return a documentfragment node.
... var ownerdocument = document.implementation.createdocument("", "test", null); var newfragment = processor.transformtofragment(domtobetransformed, ownerdocument); xsltprocessor.transformtofragment() will only produce html dom objects if the owner document is itself an htmldocument, or if the output method of the stylesheet is html.

AudioParam.value - Web APIs
consider this example: const source = new audiobuffersourcenode(...); const rate = 5.3; source.playbackrate.value = rate; console.log(source.playbackrate.value === rate); the log output will be false, because the playback rate parameter, rate, was converted to the 32-bit floating-point number closest to 5.3, which yields 5.300000190734863.
... one solution is to use the math.fround() method, which returns the single-precision value equivalent to the 64-bit javascript value specified—when setting value, like this: const source = new audiobuffersourcenode(...); const rate = math.fround(5.3); source.playbackrate.value = rate; console.log(source.playbackrate.value === rate); in this case, the log output will be true.

Advanced techniques: Creating and sequencing audio - Web APIs
when outputting sound to a file or speakers we need to have a number to represent 0db full scale — the numerical limit of the fixed point media or dac.
... in floating point audio, 1 is a convenient number to map to "full scale" for mathematical operations on signals, so oscillators, noise generators and other sound sources typically output bipolar signals in the range -1 to 1.

Using the Web Audio API - Web APIs
you have input nodes, which are the source of the sounds you are manipulating, modification nodes that change those sounds as desired, and output nodes (destinations), which allow you to save or hear those sounds.
...for the most part, you don't need to create an output node, you can just connect your other nodes to baseaudiocontext.destination, which handles the situation for you: track.connect(audiocontext.destination); a good way to visualise these nodes is by drawing an audio graph so you can visualize it.

Functions - JavaScript
a function in javascript is similar to a procedure—a set of statements that performs a task or calculates a value, but for a procedure to qualify as a function, it should take some input and return an output where there is some obvious relationship between the input and the output.
...the stack-like behavior can be seen in the following example: function foo(i) { if (i < 0) return; console.log('begin: ' + i); foo(i - 1); console.log('end: ' + i); } foo(3); // output: // begin: 3 // begin: 2 // begin: 1 // begin: 0 // end: 0 // end: 1 // end: 2 // end: 3 nested functions and closures you may nest a function within another function.

...you can capture these for analysis and handling by your code—or just to avoid having them cluttering up your output—by adding a handler for the unhandledrejection event, like this: window.addeventlistener("unhandledrejection", event => { /* you might start here by adding code to examine the promise specified by event.promise and the reason in event.reason */ event.preventdefault(); }, false); by calling the event's preventdefault() method, you tell the javascript runtime not to do its defau...

String.prototype.matchAll() - JavaScript
() prior to the addition of matchall to javascript, it was possible to use calls to regexp.exec (and regexes with the /g flag) in a loop to obtain all the matches: const regexp = regexp('foo[a-z]*','g'); const str = 'table football, foosball'; let match; while ((match = regexp.exec(str)) !== null) { console.log(`found ${match[0]} start=${match.index} end=${regexp.lastindex}.`); // expected output: "found football start=6 end=14." // expected output: "found foosball start=16 end=24." } with matchall available, you can avoid the while loop and exec with g.
... instead, by using matchall, you get an iterator to use with the more convenient for...of, array spread, or array.from() constructs: const regexp = regexp('foo[a-z]*','g'); const str = 'table football, foosball'; const matches = str.matchall(regexp); for (const match of matches) { console.log(`found ${match[0]} start=${match.index} end=${match.index + match[0].length}.`); } // expected output: "found football start=6 end=14." // expected output: "found foosball start=16 end=24." // matches iterator is exhausted after the for..of iteration // call matchall again to create a new iterator array.from(str.matchall(regexp), m => m[0]); // array [ "football", "foosball" ] matchall will throw an exception if the g flag is missing.
