• How to extend the Eclipse Java Editor to add coloured overlays

  - by Gavin Clarke

  I have an idea for an Eclipse plugin which I've been toying with. I need to be able to extend the Eclipse Java Editor component and add coloured overlays to the code based on pluggable external metrics. Unfortunately there doesn't appear to be any kind of syntax highlighting extension point. Does anyone know how I might be able to extend the exisitng eclipse Java Editor to add custom highlighting rules? Bear in mind I'm new to Eclipse plugin programming so please give as much detail as possible.

• Dynamically add a field to an object in matlab

  - by Marc

  Say I have a MATLAB object defined in a class file classdef foo properties bar end end And I create a foo object myfoo = foo(); Now I want to add another field to foo dynamically.

• bash: assign grep regex results to array

  - by Ryan

  Hello everyone, I am trying to assign a regular expression result to an array inside of a bash script but I am unsure whether that's possible, or if I'm doing it entirely wrong. The below is what I want to happen, however I know my syntax is incorrect: indexes[4]=$(echo b5f1e7bfc2439c621353d1ce0629fb8b | grep -o '[a-f0-9]\{8\}') such that: index[1]=b5f1e7bf index[2]=c2439c62 index[3]=1353d1ce index[4]=0629fb8b Any links, or advice, would be wonderful :)

• Indirect function call in JavaScript

  - by Art

  There are things like f.call(...) f.apply(...) But then there's this (1, alert)('Zomg what is this????!!!11') "1" does not seem to mean much in this context, the following works just fine: (null, alert)('Zomg what is this????!!!11') (1, null, alert)('Zomg what is this????!!!11') (undefined, alert)('Zomg what is this????!!!11') Could you point to a specific part of ECMAScript which describes that syntax?

• Combining the UNIQUE and CHECK constraints

  - by Bobby

  I have a table with columns a b and c, and if c is false then I only want to allow insertions if columns a and b are unique, but if c is true then a and b do not need to be unique. Example: There can only be one (foo, bar, false) in the table, but no limit on how many (foo, bar, true) there can be. I tried something like CONSTRAINT blah UNIQUE (a,b) AND CHECK (C is TRUE) but I can't figure out the correct syntax.

• Flex: Using NumericStepper as an itemEditor in a DataGrid

  - by AlexH

  I am trying to make one field in a datagrid editable with a numeric stepper. My current attempts look like they are working, but the dataProvider is not actually being changed. Based on what I have read in a billion different places, the syntax should be < mx:DataGridColumn dataField="a" itemRenderer="mx.controls.NumericStepper" rendererIsEditor="true" editorDataField="value" / > I have tried several variations on this theme, and nothing seems to work. What am I missing?

• Learning Lisp - Why ?

  - by David

  I really feel that I should learn Lisp and there are plenty of good resources out there to help me do it. I'm not put off by the complicated syntax, but where in "traditional commercial programming" would I find places it would make sense to use it instead of a procedural language. Is there a commercial killer-app out there that's been written in Lisp ?

• Why use infinite loops?

  - by Moishe

  Another poster asked about preferred syntax for infinite loops. A follow-up question: Why do you use infinite loops in your code? I typically see a construct like this: for (;;) { int scoped_variable = getSomeValue(); if (scoped_variable == some_value) { break; } } Which lets you get around not being able to see the value of scoped_variable in the for or while clause. What are some other uses for "infinite" loops?
