• ESLint
• TSLint
• MSBuild (both msbuild.exe and dotnet build commands)
• ScalaStyle
• AndroidLint
• DartLint
• SwiftLint (0.49.1 or later)

Supported code duplication detectors.

• GitHub Enterprise
• GitLab

Prerequisite

Node.js v14 or later

Installation

Install it globally using npm

$ npm i -g @codecoach/cli

or Yarn

$ yarn global add @codecoach/cli

Usage

Use command codecoach with required config.

Configs

Configuration could be supplied by arguments options or config JSON file.

Example: Supplying config by options

$ codecoach \
  -g="github"
  --githubRepoUrl="https://github.com/codeleague/codecoach" \
  --githubPr=99 \
  --githubToken="yourtoken" \
  -f="eslint;/path/to/eslintoutput.json" \
  -f="dotnetbuild;/path/to/dotnetbuild;/repo/src" \
  -r

Example: Supplying config by json

$ codecoach --config="codecoach.json"

and in codecoach.json

{
  "vcs": "github",
  "githubRepoUrl": "https://github.com/codeleague/codecoach",
  "githubPr": 99,
  "githubToken": "yourtoken",
  "buildLogFile": [
    "eslint;/path/to/eslintoutput.json",
    "dotnetbuild;/path/to/dotnetbuild;/repo/src"
  ],
  "removeOldComment": true
}

Will do the same thing.

Warning: If both config file and options are supplied, options will override config in file.

Option	Required	Value	Description
vcs / -g	when dryRun is false	github or gitlab
githubRepoUrl	when vcs is github		Repository's HTTPS URL
githubPr	when vcs is github		Pull request ID
githubToken	when vcs is github		Personal Access Token
gitlabHost	when vcs is gitlab	https://gitlab.company.com	GitLab Server (Could also be https://gitlab.com)
gitlabProjectId	when vcs is gitlab		Project ID
gitlabMrIid	when vcs is gitlab		MergeRequest IID (not to be confused with ID)
gitlabToken	when vcs is gitlab		Access Token
buildLogFile / -f	yes, repeatable		Read below
output / -o	no		CodeCoach parsed output for debugging
removeOldComment / -r	no	true or false	Remove CodeCoach's old comments before adding new one
failOnWarnings	no	true or false	Fail the job when warnings are found
dryRun	no	true or false	Running CodeCoach without reporting to VCS
silent	no	true or false	Disable the comment but still report job status to the VCS
suppressRules	no	rule-group-1/.* rule-id-1 rule-id-2	Rule IDs that CodeCoach will still comment but no longer treated as errors or warnings
outputFormat	no	default, gitlab	Output file format

--buildLogFile or -f

Required, Repeatable

Build log content files config. Splitted in to 3 part, formatted in <type>;<path>[;<cwd>]

• Type: one of dotnetbuild, msbuild, tslint, eslint, scalastyle, androidlint or dartlint
• Path: Path to lint output file to be processed
• cwd: Linter context repository root (optional, will use current directory if not provided)

For example,
Case 1: Run CodeCoach from repo root for eslint and dotnetbuild in the same lint context directory

--buildLogFile="eslint;./src/client/eslint-out.json" --buildLogFile="dotnetbuild;./src/api/msbuild.log"

Case 2: Run CodeCoach from somewhere else for androidlint (linter context root was /path/to/project/root)

--buildLogFile="androidlint;./android-lint.xml;/path/to/project/root"

How to get lint output for CodeCoach

ESLint

Use -o <filename> to output lint result to file and -f json to format logs as JSON. (ref.)

TSLint

Use -o <filename> to output lint result to file and -t json or --format json to format logs as JSON. (ref.)

MSBuild and dotnet build

Use -fileLoggerParameters or -flp switch with msbuild, dotnet build or dotnet msbuild command to send logs to file. (ref.)

ScalaStyle

Result is already written to target/scalastyle-result.xml when project is built (ref.)

AndroidLint

Use -o <filename> to output lint result to file (ref.)

DartLint

Use -o <filename> on output lint result created by command dart analyze > <filename> in dart project (ref.)

SwiftLint

Use --output <filename> to output lint result to file and --reporter json to format logs as JSON. (ref.)
