picklog v2.3.2

Picklog

根据你设置的filter，提取出你需要的log，从而生成changelog。可以生成JSON或markdown。

( Pickup the logs that you filter, so you can generation changelog from it. You can get JSON or markdown you want. )

快速上手 ( Usage )

$ npm install -g picklog
$ picklog init
$ picklog -o CHANGELOG.md

运行完 picklog init 后，会在你的项目下生成.picklogrc.js文件。你可以通过修改.picklogrc.js文件里的规则来控制changelog的生成。

( After running picklog init, it generator a file .picklogrc.js in your project. You can modify .picklogrc.js to control the rules to generator changelog. Scroll up to see more detail. )

CLI

• init

  生成配置文件.picklogrc.js ( Generator a setting file .picklogrc.js )

  e.g: picklog init

• -w or --write

  把输出添加到指定文件 ( Append stdout to a file )

  e.g: picklog -w CHANGELOG.md

• -o or --overwrite

  把输出覆盖到指定文件 ( Overwrite stdout to a file )

  e.g: picklog -o CHANGELOG.md

• -l or --latest

  只获取距离上一次tag间的修改 ( Only pick latest changes after the last tag )

  e.g: picklog -l -w CHANGELOG.md

• -g or --gitLogArgs

  透传给git log的参数，以英文逗号分隔 ( Pass the arg to "git log". Splited by comma )

  e.g: picklog -g v2.0.0 -w CHANGELOG.md

• -c or --config

  指定配置文件，默认是.picklogrc.js ( Custom config file. Default ".picklogrc" )

  e.g: picklog -c .picklogrc.dev.js

API

const picklog = require('picklog');

picklog({
  latest: true, // The same as CLI '--latest'
  gitLogArgs: 'v2.0.0', // The same as CLI '--gitLogArgs'
}).then(function(markdownText){
  console.log(markdownText);
});

.picklogrc.js

这是一个输出为json的demo。( Here is demo that the output is json. )

module.exports = {
  filters: [
    {
      name: 'Features',
      regExp: /^(?:feat|add)/i,
    },
    {
      name: 'Bugfixes',
      regExp: /^fix/i,
    }
  ],
  parse(commits){
    return JSON.stringify(commits, null, 2);
  },
  tagFilter: /^v\d+\.\d+\.\d+$/, // Optional
};

我想要Markdown ( I want Markdown )

如果你需要输出为markdown，你可以用以下的 .picklogrc.js 。( If you want markdown output, you can use .picklogrc.js like this: )

module.exports = {
  filters: [
    {
      name: 'Features',
      regExp: /^(?:feat|add)/i,
    },
    {
      name: 'Bugfixes',
      regExp: /^fix/i,
    }
  ],
  parse(commits){
    let output = '';

    commits.forEach((log) => {
      let date = new Date(log.timestamp * 1000);
      date = `${date.getFullYear()}-${('0' + (date.getMonth() + 1)).substr(-2)}-${('0' + date.getDate()).substr(-2)}`;

      output += `### ${log.tag} (${date})\n\n`;

      log.results.forEach((result) => {
        result.commits.forEach((commit) => {
          output += `* ${commit.s}(${commit.h})\n`;
        });

        output += '\n';
      });

      output += '\n\n';
    });

    return output;
  },
  tagFilter: /^v\d+\.\d+\.\d+$/, // Optional
};

适配AngularJS推荐的Git Commit格式 ( AngularJS Git Commit Guidelines )

AngularJS Git Commit Guidelines

const origin = '<%= GitURL %>';
const comparePath = `${origin}/compare/`;
const commitPath = `${origin}/commit/`;

module.exports = {
  filters: [
    {
      name: 'Features',
      regExp: /^(?:feat|add)/i,
    },
    {
      name: 'Bugfixes',
      regExp: /^fix/i,
    }
  ],
  parse(commits){
    // RegExp.prototype.toJSON = RegExp.prototype.toString; // JSON.stringify会调用正则表达式的toJSON
    // return JSON.stringify(commits, null, 2); // output commits

    let output = '';

    commits.forEach((log) => {
      let date = new Date(log.timestamp * 1000);
      date = `${date.getFullYear()}-${('0' + (date.getMonth() + 1)).substr(-2)}-${('0' + date.getDate()).substr(-2)}`;

      let currentTag = log.tag || log.commits[0].h;
      let prevTag = log.previousTag || log.commits[log.commits.length - 1].h;
      output += `### [${currentTag}](${comparePath}${prevTag || ''}...${currentTag}) (${date})\n\n`;

      log.results.forEach((result) => {
        output += `#### ${result.filter.name}\n`;

        result.commits.forEach((commit) => {
          output += `* ${commit.s}([${commit.h}](${commitPath}${commit.h}))\n`;
        });

        output += '\n';
      });

      output += '\n\n';
    });

    return output;
  },
  tagFilter: /^v\d+\.\d+\.\d+$/, // Optional
};
