asp.net mvc - VS 2013 telling me Use lamba expression -


my issue comes layers.add part. i'm brand new mvc, razor, linq , telerik's kendoui using map widget. layers.add() function gets green squiggly line message "use lambda expression". why getting this? help. link here

@(html.kendo().map()       .name("map")       .center(39.6924, -97.3370)       .zoom(4)       .layers(layers =>       {           layers.add()               .style(style => style.fill(fill => fill.opacity(0.7)))               .type(maplayertype.shape)               .datasource(datasource => datasource                   .geojson()                   .read(read => read.url(url.content("~/scripts/gz_2010_us_040_00_500k.js")))               );       })       .events(events => events            .shapecreated("onshapecreated")            .shapemouseenter("onshapemouseenter")            .shapemouseleave("onshapemouseleave")         ) )

the ide suggesting shorten lambda. suppose f function returns void. both of following same:

x => { f(x); } x => f(x)

so code shortened replacing this:

layers => {     layers.add()         .style(style => style.fill(fill => fill.opacity(0.7)))         .type(maplayertype.shape)         .datasource(datasource => datasource             .geojson()             .read(read => read.url(url.content("~/scripts/gz_2010_us_040_00_500k.js")))         ); }

with this:

layers => layers.add()     .style(style => style.fill(fill => fill.opacity(0.7)))     .type(maplayertype.shape)     .datasource(datasource => datasource         .geojson()         .read(read => read.url(url.content("~/scripts/gz_2010_us_040_00_500k.js")))      )

for legibility reasons may or may not want make change.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
