Devreplay is static analysis tool based on your own programming rule.

• Visual Studio Code
• Other Editor Support (Language Server)

How to use

1. Install on local

$ npm install devreplay
# or
$ yarn global add devreplay

1. Put your own programming rule(.devreplay.json) on the project like bellow

[
  {
    "before": [
      "(?<tmp>.+)\\s*=\\s*(?<a>.+)",
      "\\k<a>\\s*=\\s*(?<b>.+)",
      "\\k<b>\\s*=\\s*\\k<tmp>"
    ],
    "after": [
      "$2, $3 = $3, $2"
    ],
    "isRegex": true
  }
]

1. Run the devreplay

devreplay yourfile.py

or get fixed code

devreplay --fix yourfile.py > yourfile.py

The target source code file will be

- tmp = a
- a = b
- b = a
+ a, b = b, a

• Step up: Make the rule message and severity. Also after can be more abstract

[
  {
    "before": [
      "(?<tmp>.+)\\s*=\\s*(?<a>.+)",
      "\\k<a>\\s*=\\s*(?<b>.+)",
      "\\k<b>\\s*=\\s*\\k<tmp>"
    ],
    "after": [
      "$2, $3 = $3, $2"
    ],
    "isRegex": true,
    "author": "Yuki Ueda",
    "message": "Value exchanging can be one line",
    "severity": "info"
  }
]

• severity means how this rule is important
  • error
  • warning
  • info
  • hint
• Run devreplay again

$ devreplay yourfile.py
./yourfile.py
  15:1  warning  Value exchanging can be one line  0

Also, you can use default rules by extends some rules such as

[
  "python"
]

Make rules by using Regular Expression

{
  "before": [
    "([a-z]+)-([a-z]+)"
  ],
  "after": [
      "$1 $2"
  ],
  "isRegex": true
}

That will fix

- print("hello-world")
+ print("hello world")
