The Fuck

The Fuck是一款很棒的应用程序，灵感来自@liamosaur推文，它可以纠正之前控制台命令中的错误

更多示例：

➜ apt-get install vim
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

➜ fuck
sudo apt-get install vim [enter/↑/↓/ctrl+c]
[sudo] password for nvbn:
Reading package lists... Done
...

➜ git push
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin master


➜ fuck
git push --set-upstream origin master [enter/↑/↓/ctrl+c]
Counting objects: 9, done.
...

➜ puthon
No command 'puthon' found, did you mean:
 Command 'python' from package 'python-minimal' (main)
 Command 'python' from package 'python3' (main)
zsh: command not found: puthon

➜ fuck
python [enter/↑/↓/ctrl+c]
Python 3.4.2 (default, Oct  8 2014, 13:08:17)
...

➜ git brnch
git: 'brnch' is not a git command. See 'git --help'.

Did you mean this?
    branch

➜ fuck
git branch [enter/↑/↓/ctrl+c]
* master

➜ lein rpl
'rpl' is not a task. See 'lein help'.

Did you mean this?
         repl

➜ fuck
lein repl [enter/↑/↓/ctrl+c]
nREPL server started on port 54848 on host 127.0.0.1 - nrepl://127.0.0.1:54848

如果您不怕盲目运行更正后的命令，可以禁用REQUIRED_CONFIRMATION设置选项：

➜ apt-get install vim
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

➜ fuck
sudo apt-get install vim
[sudo] password for nvbn:
Reading package lists... Done
...

安装

python (3.4+)
pip
python-dev

在MacOS上，您可以通过Homebrew(或Linux上的Linuxbrew)安装Fuck：

brew install thefuck

在Ubuntu/Mint上，使用以下命令安装Fuck：

sudo apt update
sudo apt install python3-dev python3-pip python3-setuptools
sudo pip3 install thefuck

在FreeBSD上，使用以下命令安装Fuck：

pkg install thefuck

在ChromeOS上，使用以下命令使用chromebrew安装Fuck：

crew install thefuck

在其他系统上，使用pip安装Fuck：

pip install thefuck

或者，您也可以使用操作系统包管理器(OS X、Ubuntu、Arch)

#建议您将此命令放在.bash_profile、.bashrc、.zshc或其他启动脚本中：

eval $(thefuck --alias)
# You can use whatever you want as an alias, like for Mondays:
eval $(thefuck --alias FUCK)

或者在您的shell配置中(bash、zsh、Fish、powershell、tcsh)

更改仅在新的shell会话中可用。要使更改立即可用，请运行source~/.bashrc(或您的shell配置文件，如.zshc)

要在没有确认的情况下运行已修复的命令，请使用–yes选项(或者简称为-y，如果您特别沮丧，则使用–hard)：

fuck --yeah

要递归修复命令直到成功，请使用-r选项：

fuck -r

卸载

pip3 install thefuck --upgrade

注意：别名功能在Fuck的1.34版中已更改

它是如何工作的

要删除，请颠倒安装过程：-从您的Bash、zsh、Fish、powershell、tcsh中删除或注释别名行。shell配置-使用软件包管理器(BREW、PIP3、pkg、Crew、pip)卸载二进制文件

设置

要添加您自己的规则，请在~/.config/TheMASH/Rules中创建一个名为your-Rule-name.py的文件。规则文件必须包含两个函数：

match(command: Command) -> bool
get_new_command(command: Command) -> str | list[str]

此外，规则可以包含可选函数：

side_effect(old_command: Command, fixed_command: str) -> None

规则还可以包含可选变量Enabled_by_Default、Requires_Output和Priority

命令有三个属性：script、output和script_part。您的规则不应更改命令

规则API在3.0中发生了更改：要访问规则的设置，请使用Fuck.conf导入设置将其导入

Settings是一个特殊的对象，它由~/.config/the妈的/settings.py和env中的值组合而成(参见下面的更多内容)

使用sudo运行脚本的一个简单示例规则：

def match(command):
    return ('permission denied' in command.output.lower()
            or 'EACCES' in command.output)


def get_new_command(command):
    return 'sudo {}'.format(command.script)

# Optional:
enabled_by_default = True

def side_effect(command, fixed_command):
    subprocess.call('chmod 777 .', shell=True)

priority = 1000  # Lower first, default is 1000

requires_output = True

更多规则示例、用于规则的实用程序函数、特定于应用程序/操作系统的帮助器

带规则的第三方包

可以在文件$XDG_CONFIG_HOME/the他妈的/settings.py($XDG_CONFIG_HOME默认为~/.config)中更改几个Fuck参数：

rules – list of enabled rules, by default thefuck.const.DEFAULT_RULES;
exclude_rules – list of disabled rules, by default [];
require_confirmation – requires confirmation before running new command, by default True;
wait_command – the max amount of time in seconds for getting previous command output;
no_colors – disable colored output;
priority – dict with rules priorities, rule with lower priority will be matched first;
debug – enables debug output, by default False;
history_limit – the numeric value of how many history commands will be scanned, like 2000;
alter_history – push fixed command to history, by default True;
wait_slow_command – max amount of time in seconds for getting previous command output if it in slow_commands list;
slow_commands – list of slow commands;
num_close_matches – the maximum number of close matches to suggest, by default 3.
excluded_search_path_prefixes – path prefixes to ignore when searching for commands, by default [].

settings.py的一个示例：

rules = ['sudo', 'no_command']
exclude_rules = ['git_push']
require_confirmation = True
wait_command = 10
no_colors = False
priority = {'sudo': 100, 'no_command': 9999}
debug = False
history_limit = 9999
wait_slow_command = 20
slow_commands = ['react-native', 'gradle']
num_close_matches = 5

或通过环境变量：

THEFUCK_RULES – list of enabled rules, like DEFAULT_RULES:rm_root or sudo:no_command;
THEFUCK_EXCLUDE_RULES – list of disabled rules, like git_pull:git_push;
THEFUCK_REQUIRE_CONFIRMATION – require confirmation before running new command, true/false;
THEFUCK_WAIT_COMMAND – the max amount of time in seconds for getting previous command output;
THEFUCK_NO_COLORS – disable colored output, true/false;
THEFUCK_PRIORITY – priority of the rules, like no_command=9999:apt_get=100,
rule with lower priority will be matched first;
THEFUCK_DEBUG – enables debug output, true/false;
THEFUCK_HISTORY_LIMIT – how many history commands will be scanned, like 2000;
THEFUCK_ALTER_HISTORY – push fixed command to history true/false;
THEFUCK_WAIT_SLOW_COMMAND – the max amount of time in seconds for getting previous command output if it in slow_commands list;
THEFUCK_SLOW_COMMANDS – list of slow commands, like lein:gradle;
THEFUCK_NUM_CLOSE_MATCHES – the maximum number of close matches to suggest, like 5.
THEFUCK_EXCLUDED_SEARCH_PATH_PREFIXES – path prefixes to ignore when searching for commands, by default [].

例如：

export THEFUCK_RULES='sudo:no_command'
export THEFUCK_EXCLUDE_RULES='git_pull:git_push'
export THEFUCK_REQUIRE_CONFIRMATION='true'
export THEFUCK_WAIT_COMMAND=10
export THEFUCK_NO_COLORS='false'
export THEFUCK_PRIORITY='no_command=9999:apt_get=100'
export THEFUCK_HISTORY_LIMIT='2000'
export THEFUCK_NUM_CLOSE_MATCHES='5'

实验即时模式

如果您希望制定一组特定的非公共规则，但仍希望与其他人共享这些规则，请创建一个名为TheMASH_CONTRIB_*的包，其结构如下：

thefuck_contrib_foo
  thefuck_contrib_foo
    rules
      __init__.py
      *third-party rules*
    __init__.py
    *third-party-utils*
  setup.py

操蛋将在规则模块中查找规则

Fuck的默认行为需要时间来重新运行先前的命令。在即时模式下，Fuck通过使用脚本记录输出，然后读取日志来节省时间

目前，即时模式仅支持带有bash或zsh的Python3。为了正常工作，还需要禁用zsh的自动更正功能

要启用即时模式，请向.bashrc、.bash_profile或.zshc中的别名初始化添加–enable-explementation-instant-mode

请参阅CONTRIBUTING.md

eval $(thefuck --alias --enable-experimental-instant-mode)
