javascript - Make browserify modules external with Gulp -


i have library lib.js want create lib/a.js , lib/b.js , able use script client.js using var = require('lib/a.js'); , works when include compiled lib.js library before client.js (therefore, lib.js has declare require function knows lib/a.js)

i guess have use external , alias not sure proper way it

also, possible have gulp file creates alias automatically folders in library? eg. creates alias files in lib/ dir?

here couple of gulp tasks build common lib.js , client.js bundles separately.

note have tell browserify b.require() lib/*.js when bundling lib.js, , have tell b.external() libraries loaded separately when bundling client.js

var path = require('path'); var gulp = require('gulp'); var browserify = require('browserify'); var concat = require('gulp-concat'); var transform = require('vinyl-transform');  gulp.task('build-lib', function () {    // use `vinyl-transform` wrap around regular readablestream returned b.bundle();   // can use down vinyl pipeline vinyl file object.   // `vinyl-transform` takes care of creating both streaming , buffered vinyl file objects.   var browserified = transform(function(filename) {      // basename, eg: 'a.js'     var basename = path.basename(filename);      // define exposed name client.js use require();     // eg: require('lib/a.js'); // -> exposed name should 'lib/a.js'     var expose = 'lib/' + basename;      return browserify(filename)       .require(filename, { expose: expose})       .bundle();   });    return gulp.src(['./lib/*.js'])     .pipe(browserified)     .pipe(concat('lib.js'))     .pipe(gulp.dest('./dist')); });  gulp.task('build-client', function () {    var browserified = transform(function(filename) {     // filename = './client.js'      // let browserify know lib/a.js , and lib/b.js external files     // , loaded externally (in case, loading bundled lib.js      // eg: <script src='dist/lib.js'>)     return browserify(filename)       .external('lib/a.js')       .external('lib/b.js')       .bundle();   });    return gulp.src(['./client.js'])     .pipe(browserified)     .pipe(gulp.dest('./dist')); });  gulp.task('default', ['build-lib', 'build-client']);

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

first of all, thank being patient know simple question more couple of weeks' experience figure out. i've seen folks persevere , helpful on here , hope you're willing me. here fiddle: http://jsfiddle.net/65uzf/ here 1 of places searched answers on here: ( vertically center image thumbnails fix-sized div ) tried solutions on there , didn't work out me. i've searched ~4 or 5 others, , been unsuccessful those, too. what want take large image (what linked background-image #ysypic , #tabpic divs) , display thumbnail version of image in confines of divs have set it. is, using background properties have laid out in css, portion of image displays inside of circular divs. without these properties, display defaults smaller section of image [presumably pi*(50^2) area in top left] terrible resolution. i not care if entire image doesn't display inside of circles (it won't, given difference in shape), , overflow not being displayed fine. want able see figu

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
