如何在 Squeak 中加載 Metacello？

Question

眾所周知，Metacello 的第一個或主要目標是 Pharo，但現在似乎支持 Squeak 4 。 我已經嘗試過，但由於缺少方法而失敗。 從成績單：

我正在使用 Squeak 4.4-12327 圖像。 這有什么幫助嗎？

Answer 1

我剛剛在 4.4 中運行了這個（按照 Github 上的安裝文檔的建議）並且沒有任何問題：

Installer gemsource
project: 'metacello';
install: 'ConfigurationOfMetacello'. 

((Smalltalk at: #ConfigurationOfMetacello) project 
  version: '1.0-beta.32') load.

你用的是什么代碼？

Answer 2

上述解決方案不再有效

你需要使用下面的代碼來獲取它

(Installer monticello http:'http://seaside.gemtalksystems.com/ss')
project: 'metacello';
install: 'ConfigurationOfMetacello'. 

((Smalltalk at: #ConfigurationOfMetacello) project 
  latestVersion) load.

Answer 3

FWIW，到目前為止，Metacello 安裝已集成到 Squeak 中，因為 Squeak 5.3（可能更早）。

要通過 UI 加載 Metacello，請打開主停靠欄中的應用程序菜單，然后選擇首選項向導。 按 Done，然后在下一個視圖中，選擇 Metacello 進行安裝。

要從代碼加載 Metacello， Installer ensureRecentMetacello在任何工作區/CodeHolder 中評估Metacello new或Installer ensureRecentMetacello ensureRecentMetacello。
