i have string m(2,n(3)) . i need retrieve matches (calls) regex: m(2,n(3)) n(3) my variant of regex - (m|n\((.*?)\)) it doesn't work. you can make use of balanced constructs in .net regex. positive look-ahead can match nested expressions this: (?=(\b\w+\b\((?>[^()]+|\((?<n>)|\)(?<-n>))*(?(n)(?!))\))) the values stored in group 1. see demo (go table tab see actual results). var rx = new regex(@"(?=(\b\w+\b\((?>[^()]+|\((?<n>)|\)(?<-n>))*(?(n)(?!))\)))"); var str = "m(2,n(3)), call(param,3)"; var matches = rx.matches(str).oftype<match>().select(p => p.groups[1].value).tolist();

since gapi stopped working 2 days ago had rewrite code google analytics dashboard. decided use google api php client ( https://github.com/google/google-api-php-client ) got working pretty nice @ local vagrant ubuntu server when deploy code remote webserver 500 php error. when checking logs discover error message creates (403) quota error: user rate limit exceeded. how can code working on vagrant not on remote webserver? domains both added correctly developers console. tried setting query/user/second-setting 10 or more not change anything. allright, fixed it: i added sleep(1); php foreach loop querying google analytics profiles have in account. apparently vps querying google's api faster local development environment , therefore not getting errors local.

i have following query declare lv_duration int; set @lv_duration = 0; select @lv_duration := timestampdiff(second, changedon,now()) `transactionhistory` transaction_id = trim(_transaction) order tsh_id desc limit 1; in getting time since last entry of transaction_id fields.but taking .25 of second in relative mid size table.my primary auto-increment field tsh_id. have index on transaction_id field. think ordering , taking last record might have performance impact. alternative it? from order by optimisation link supplied mcadam331 believe query matches pattern: select * t1 key_part1 = constant order key_part2; a composite index on (transaction_id,tsh_id) should speed up. i don't think there quicker way limit latest record.

i'm writing shader in cg language unity3d. if make shader transparent object need create 2 similar passes in subshader . first 1 render faces (with cull front ) , second 1 render front faces (with cull back ). code vertex , fragment function same 2 passes. is possible not double code , declare functions, shared between passes? want have in code example: shader "cool shader" { properties { ... } subshader { cgprogram // need declare vertexoutput somewhow here float4 sharedfragfoo(vertexoutput i) : color // how make smth this? { .... return float4(...); } endcg pass { cgprogram #pragma vertex vert #pragma fragment frag vertexoutput vert(vertexinput v) { vertexoutput o; ... return o; } float4 frag(vertexoutput i) : color { return sharedfragfoo(i); // call shared between passes function } ...
