How to launch a Bash function using Git alias

由 拈花ヽ惹草 提交于 2019-12-10 20:27:43
问题 I want to use a Git alias in ~/.gitconfig so that it calls a bash function, if it is defined, otherwise call the regular git checkout . This is what I have devised: cat ~/.gitconfig ... [alias] ... co = !(compgen -A function vxzExecuteGitCheckout >/dev/null && vxzExecuteGitCheckout ) || git checkout The problem is that Git uses /bin/sh (which happens to be dash in my case) and it barfs on compgen since it is a bash builtin. Any way making sure that Git uses bash to execute this command? Note

Aliasing find directory in Unix

问题 I tried something like: alias fdi 'find . -type d -iname "*\!^*"' but this only looks for exact names passed as argument. fdi abc will only output: ./d/abc not this: ./d/greabcyup I am not just looking for exact name. It should also show ./d/greabcyup Update: I did echo $0 tcsh 回答1: Is this c-shell or tcsh? I dbl-checked with orielly lunix in a nutshell , !^ is meant to be the first word in the current command line, so I don't think it is doing what you want. You can dbl check that theory for

Type aliasing to avoid name clash in type refinement

由 若如初见. 提交于 2019-12-10 20:02:02
问题 Can I use aliasing so I don't need to change either of the type parameter/member in the following name clash situation: trait Bar { type A } trait Foo { def get[A]: Option[Bar { type A = A }] // "illegal cyclic reference" } I know I can write trait Foo { def get[A1]: Option[Bar { type A = A1 }] } But I would really prefer not to change the type name. 回答1: You could e.g. do something like this: trait Bar { type A } trait Foo { type M[X] = Bar { type A = X } def get[A]: Option[M[A]] } Or inline

Is it possible to access environment variables without the '$' in bash? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . This may seem pretty trivial but I am a novice in bash scripting and I could not find the answer elsewhere. I have mplayer installed on ubuntu 13.04 and I am using it to stream internet radio stations. Normally you need to provide the ip as argument for that: mplayer http://176.31.113.37:8080 I have created an

MailKit: How to get the To email address when it is an alias

由 余生长醉 提交于 2019-12-10 18:52:20
问题 I am sending an email to alias@company.com which is an alias to a real mailbox address. I then connect to the real mailbox (let's say realmailbox@company.com) using MailKit and retrieve messages. When I inspect the To address, all I see is the realmailbox@company.com. How to I see the original alias address that the email was sent to? For example: var fullMessage = imapClient.Inbox.GetMessage(uid); var recipients = fullMessage.To; recipients only show the realmailbox@company.com, not the

Python Click multiple command names

由 本秂侑毒 提交于 2019-12-10 18:38:45
问题 Is it possible to do something like this with Python Click? @click.command(name=['my-command', 'my-cmd']) def my_command(): pass I want my command lines to be something like: mycli my-command and mycli my-cmd but reference the same function. Do I need to do a class like AliasedGroup? 回答1: AliasedGroup is not what you are after, since it allows a shortest prefix match, and it appears you need actual aliases. But that example does provide hints in a direction that can work. It inherits from

利用alias简化进入较深的路径

由 那年仲夏 提交于 2019-12-10 17:22:17
有时候我们需要频繁的进入比较深的目录，每次都cd 对应的路径到达的话，就很麻烦。为了简化这一过程我们可以借助 alias 这一命令。 如何做 话不多说，直接进入主题。 vim ~/.bashrc 进入basnihrc文件。 在该文件中添加 alias myCD = 'cd /home/**/**/***/**' 保存并退出文件，在终端输入 source ~/.bashrc 刷新一下。 在终端中输入 myCD ，就发现直接跳转到我们指定的路径了。 实现了我们的目的之后，再来了解了解alias命令吧。 alias 作用 alias命令用来设置指令的别名。我们使用该命令可以将一些较长的命令进行简化。 注意 使用alias时，用户必须使用单引号’'将原来的命令引起来，防止特殊字符导致错误。 alias命令的作用只局限于该次登入的操作。若要每次登入都能够使用这些命令别名，则可将相应的alias命令存放到我们个人的bash的初始化文件 ~/.bashrc 中即可。 语法 alias(选项)(参数) 选项 -p。打印已设置的命令别名。 来源： CSDN 作者： acnowa 链接： https://blog.csdn.net/qq_38081870/article/details/103476524

Are type aliases used as type of function parameter part of the function signature?

Defining an alias for XML element in XSD Schema

由 你。 提交于 2019-12-10 15:12:08
问题 Is there XSD language support or tricks (e.g. via the preprocessor) for defining an alias for an XML element? I would like to alias all the elements in my schema in order to create an option for a more cryptic but network bandwidth-efficient version of our XML documents. For example, I would like to define a name such as IRQ to be an alias for the element InterruptRequest etc. <xs:element name="InterruptRequest" minOccurs="0"> <xs:complexType> <xs:attribute name="level" type="xs:unsignedShort
