If my package is depending on the Zinc-HTTP package, would the following baseline work for Pharo3 (which already includes Zinc)? baseline: spec <baseline> spec package: 'HttpExplorer' with: [spec requires: 'Zinc-Http']; yourself. Or is something like the following required in addition to make the configuration complete: spec project: 'Zinc-Http' with: [ spec repository: 'http://mc.stfx.eu/ZincHTTPComponents'; loads: #('Core'); version: #stable ].

What is it that Marcus always says? âThe perfect is the enemy of progressâ or something like that ;-) Sure, letâs search for a better way, but can we have some intermediate solution in the mean time?

It was not meant as condescending, but to point out that looking at Spotter from a fixed point of view is not particularly useful and prevents you from seeing its potential. Even in your post, you treat Spotter for what it already offers in terms of kinds of search, but you do not take into account the possibility of spending half an hour to build the kinds of searches that fit you better. I understand this is a radically new proposition, but because every developer has a different need catering to custom needs is an important ability that should be considered. We still have to explain the moldability part better. > The "minor" differences: > - most of the time I am searching for classes and message, I do not use > scripts and rarely search for files. > often, I know what kind of thing I am searching, messages for example, I > type in "transform" because I search for a message that starts with that > word. > - spotlight shows messages with the word "transform" > - spotter shows classes with the world "Transform", packages with the word > "Transform" and than a list of 5 method names. > Ok. Here is another feature that was not made public because it is not completely finished: if you add #i to your search, it will show only the implementors category.

Shift+Enter opens a default Spotter. But, if really needed, you can easily build your own Spotter and map it on a different key. Just provide a different input object that contains only the extensions to show.

Re: [Pharo-users] Spotter vs Spotlight was: [Re: Cleaning code completition's namespace]

I can understand Lauras point. I used spotlight quite a lot for searching messages and classes, even if I know the exact name of the message or class, so I don't use it only for "searching" but as an interface to quickly open a new Browser or MessageList. There are some minor differences that actually make a big difference, if you are used to it, more below. BUT and this is a big "but" and an advantage for spotter 1. Spotlight does not find all items and even if you type in a the exact class name that exists, the first entries spotlight shows, may only include that name. (Searching and opening a browser for String or Morph for example) 2. even if I miss spotlight, the power of spotter (searching everything, extensibility and search in the resultlist) outweigh this for me. 2015-02-07 23:38 GMT+01:00 Tudor Girba <tudor(a)tudorgirba.com>: > Hi, > > > >> In contrast, from the perspective of that need, Spotter >> -Doesn't search "names" (class names/selectors) but implementations, >> overlaping the two actions of the need (when i olny hava a clue and i'm not >> sure of the name i'm interesed into, i don't care for the list of >> implementations, is obstrusive "garbage").

Yes, but please don't just limit it to UI things. I want to be able to 'Copy an object' to an 'Object Clipboard' when I am on 'self' in an Inspector. And I want to be able to 'Paste an object' in a slot of an Inspector, or wherever that makes sense.
