如果使用http://selflanguage.org/上的文件在 Ubuntu 上安装 Self ，那么我们可以使用

$ Self
Self Virtual Machine Version 4.1.13, Sat 20 Feb 10 22:39:48 Linux
Copyright 1989-2003: The Self Group (type _Credits for credits)

for I386:  LogVMMessages = true
for I386:  PrintScriptName  = true
for I386:  Inline = true
for I386:  SICDeferUncommonBranches = false (not implemented)
for I386:  SICReplaceOnStack = false (not implemented)
for I386:  SaveOutgoingArgumentsOfPatchedFrames = true

但是，一些简单的行无法运行：

VM# 'Hello, World!' print.
A lookup error happened while sending the message
    print
to
    'Hello, World!'.
Subsequently, the lookup error message
    undefinedSelector:Receiver:Type:Delegatee:MethodHolder:Arguments:
was sent to
    <0>,
and was also not understood, causing the process to be aborted by the Self VM.

#0 (<error>:1): print = ( | self* = 'Hello, World!'. delegatee = nil. selector = 'print'. | 
"undefined selector error;
this method was automatically generated by the VM."
 )


#1 (<stdin>:1): <top level expr> = ( | self* = lobby. | 'Hello, World!' print )

或者另一个尝试插槽：

VM# _AddSlots: (| vehicle <- (|parent* = traits clonable|) |).
A lookup error happened while sending the message
    traits
to
    lobby.
Subsequently, the lookup error message
    undefinedSelector:Receiver:Type:Delegatee:MethodHolder:Arguments:
was sent to
    <0>,
and was also not understood, causing the process to be aborted by the Self VM.

#0 (<error>:1): traits = ( | self* = lobby. delegatee = nil. selector = 'traits'. | 
"undefined selector error;
this method was automatically generated by the VM."
 )


#1 (<stdin>:1): <top level expr> = ( | self* = lobby. | traits clonable )


                             ^
Self VM error: couldn't construct object literal on line 1, character 30
               ^
Self VM error: couldn't construct object literal on line 1, character 16
VM#

有人知道如何使它工作吗？

你遇到的是最基础的自我形式。

VM 本身只知道很少的消息。它们包括所有原语和一些消息，例如bootstrap.

如果您尝试它，类似_Quit或'some/path/to/self/script' _RunScript 将起作用的东西，因为这些是始终可用的原语。

如果你想要一个工作环境，你必须要么

  • -s通过使用以下选项启动 VM 来加载快照：

    Self -s mySnapshot.snap

    您可以在自我主页上找到快照。

  • 运行世界构建脚本。为此，您需要objectsself 附带的目录。如果找不到，请使用github 页面中的那个。然后，将您的工作目录更改为该objects目录并运行世界构建器脚本。

    cd $PATH_TO_OBJECTS/objects
Self -f worldBuilder.self

    或者，将SELF_WORKING_DIR环境变量指向包含该目录的objects目录并运行 sctipt。

    SELF_WORKING_DIR=$PATH_TO_OBJECTS Self -f s$PATH_TO_OBJECTS/worldBuilder.self

这引导了一个自我世界，每个已知的信息都应该被理解。

PS：当然，您也可以从正在运行的 VM 中运行 word builder 脚本：'/path/to/dir/with/objects/worldBuilder.self' _RunScript'. 但请确保设置了 SELF_WORKING_DIR。
