### Setup and Data Fetching Scripts

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Steps to set up the project by copying the configuration file and then fetching various data using Node.js scripts. The `--update-issues` flag is used for group-specs.

```bash
# Setup steps:
cp config.json.dist config.json
# Edit config.json with your GitHub API token

# Fetch all data:
node fetch-data/groups.js
node fetch-data/group-specs.js
node fetch-data/group-repos.js --update-issues
```

--------------------------------

### Create and Configure config.json

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Create the config.json file from the distribution file and add your GitHub API token. This file is required for accessing W3C and GitHub APIs.

```json
// config.json (create from config.json.dist)
{
  "ethercalc": "https://ethercalc.example.com",
  "ghapitoken": "ghp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
```

--------------------------------

### Build Repository Map

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Generate a JSON file mapping repositories using a Node.js script. The output is redirected to repo-map.json.

```bash
# Build repo map:
node build-repo-map.js > repo-map.json
```

--------------------------------

### Serve Dashboard Locally

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Serve the dashboard locally using Python's built-in HTTP server on port 8000. Access the dashboard via http://localhost:8000/index.html.

```bash
# Serve locally:
python -m http.server 8000
# Open http://localhost:8000/index.html
```

### Fetch Specifications for Working Groups

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Retrieves active specifications for each Working Group, including version history and editor's draft URLs, saving them into per-group JSON files. This script requires the 'groups.json' file to be pre-populated.

```javascript
// fetch-data/group-specs.js
const fs = require('fs/promises'),
      utils = require('../lib/utils'),
      activespecs = require('../lib/active-specs'),
      w3c = require('node-w3capi');

(async function() {
  const groups = await w3c.groups().fetch({embed:true});
  const workinggroups = groups.filter(g => g.type === 'working group');

  for (const wg of workinggroups) {
    const unfinishedSpecs = await activespecs({shortname: wg.shortname, type: "wg"});
    if (!unfinishedSpecs || !unfinishedSpecs.length) {
      console.error("no spec found for " + wg.name);
      continue;
    }

    for (const s of unfinishedSpecs) {
      const datedversion = await w3c.specification(s.shortname)
        .version(utils.specDate(s)).fetch();
      s.editorsdraft = datedversion ? datedversion["editor-draft"] : null;
      s.versions = await w3c.specification(s.shortname).versions().fetch({embed:true});
    }

    fs.writeFile("./pergroup/" + wg.id + ".json", JSON.stringify(unfinishedSpecs, null, 2));
  }
  fs.writeFile("./pergroup/spec-update.json", JSON.stringify(new Date()));
})().catch(err => console.error(err));

// Run with: node fetch-data/group-specs.js
// Output: pergroup/32061.json, pergroup/19480.json, etc.
```

--------------------------------

### Fetch W3C Working Groups List

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Retrieves all W3C Working Groups from the W3C API and saves essential metadata to a local JSON file. Run this script to populate the list of groups for subsequent data fetching.

```javascript
// fetch-data/groups.js
const fs = require('fs/promises');

(async function() {
  const workinggroups = await (await fetch("https://api.w3.org/groups/wg?embed=1")).json();
  fs.writeFile("groups.json", JSON.stringify(
    workinggroups._embedded.groups.map(g => {
      return {
        id: g.id,
        shortname: g.shortname,
        start: g["start-date"],
        end: g["end-date"],
        name: g.name
      };
    }).reduce((a, b) => {
      a[b.id] = b;
      return a;
    }, {})
  , null, 2));
})();

// Run with: node fetch-data/groups.js
// Output: groups.json containing:
// {
//   "32061": {
//     "id": 32061,
//     "shortname": "css",
//     "start": "1997-02-28",
//     "end": "2027-03-17",
//     "name": "Cascading Style Sheets (CSS) Working Group"
//   },
//   ...
// }
```

### D3.js Specification Timeline Visualization

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Visualizes W3C specification progress through recommendation stages using D3.js. It includes pan/zoom and color-coded status indicators. Requires 'groups.json' for data.

```javascript
// plot.js - Dashboard visualization
const recStages = ["FPWD", "WD", "WR/LC", "CR", "PR", "REC"];

// Status normalizer maps W3C API status to display stages
const statusNormalizer = version => {
  switch(version.status) {
    case "Candidate Recommendation":
    case "Candidate Recommendation Draft":
    case "Candidate Recommendation Snapshot":
      return "CR";
    case "Proposed Recommendation":
      return "PR";
    case "Recommendation":
      return "REC";
    case "Working Draft":
      return version._links["predecessor-version"] ? "WD" : "FPWD";
    case "First Public Working Draft":
      return "FPWD";
  }
  return version.status;
};

// Duration color scheme: green (recent) -> yellow -> red (stale)
var durationColorScheme = d3.scaleLinear()
  .domain([3, 6, 12, 24])
  .range(["#afa", "white", "yellow", "red"]);

// Load and display dashboard for a working group
fetch("groups.json")
  .then(r => r.json())
  .then(groups => {
    if (groupid) {
      dashboard(groupid, groups[groupid]);
    }
  });

// Access dashboard at: index.html?32061 (for CSS Working Group)
// Each specification shows as a line with circles at each publication milestone

```

### Generate Cross-Group Repository Map

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Consolidates GitHub repository mappings from individual group JSON files into a single map. Outputs a JSON object where keys are repository names and values are arrays of associated specifications.

```javascript
// build-repo-map.js
const fs = require("fs");

const repos = {};

fs.readdir('./pergroup/', (err, files) => {
  files.filter(f => f.match('[0-9]+-repo\.json'))
    .forEach(file => {
      const groupSpecs = JSON.parse(fs.readFileSync('./pergroup/' + file, 'utf-8'));
      Object.keys(groupSpecs).forEach(url => {
        const spec = groupSpecs[url];
        const repo = spec.repo.owner + '/' + spec.repo.name;
        const specData = {
          title: spec.title,
          recTrack: spec.recTrack,
          url: url,
          group: parseInt(file.match(/^([0-9]+)/)[1], 10)
        };
        if (!repos[repo]) {
          repos[repo] = [];
        }
        repos[repo].push(specData);
      });
    });
  console.log(JSON.stringify(repos, null, 2));
});

// Run with: node build-repo-map.js > repo-map.json
// Output example:
// {
//   "w3c/csswg-drafts": [
//     {"title": "CSS Grid Layout", "recTrack": true, "url": "https://www.w3.org/TR/css-grid-1/", "group": 32061},
//     {"title": "CSS Flexbox", "recTrack": true, "url": "https://www.w3.org/TR/css-flexbox-1/", "group": 32061}
//   ]
// }

```

### D3.js GitHub Issue Tracking Visualization

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Generates a D3.js stacked bar chart for GitHub issue lifecycles. It uses color-coding for issue age and supports toggling between stack and trail views. Requires repoinfo object.

```javascript
// issue-plot.js - Issue tracking visualization
function dashboard(repoinfo) {
  const issues = repoinfo.issues.filter(i => !i.isPullRequest);
  const repo = repoinfo.repo;

  // Duration color scheme for issue age
  var durations = {
    "-1": "issue closed during that month",
    0: "issue raised during that month",
    1: "1 month old",
    6: "6 months old",
    24: "2 years old"
  };
  var durationColorScheme = d3.scaleLinear()
    .domain([-1, 0, 1, 6, 24])
    .range(["#66f", "#afa", "white", "yellow", "red"]);

  // Build monthly issue counts
  var months = {};
  issues.forEach(function(i) {
    const startMonth = i.created_at.slice(0,7);
    const endMonth = i.closed_at ? i.closed_at.slice(0,7) : currentMonth;
    // Track issue presence in each month
    let curMonth = startMonth;
    while (curMonth <= endMonth) {
      if (!months[curMonth]) months[curMonth] = [];
      months[curMonth].push(i.number);
      curMonth = nextMonth(curMonth);
    }
  });

  // Render interactive chart with links to GitHub issues
  svg.selectAll("a.issue")
    .data(issues)
    .enter()
    .append("a")
    .attr("xlink:href", d =>
      `https://github.com/${repo.owner}/${repo.name}/issues/${d.number}`
    );
}

// Access at: issues.html?groupid=32061&shortname=css-grid-1

```

### Parse GitHub Repository from Editor's Draft URL

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Parses various URL formats (e.g., GitHub Pages, CSSWG drafts, WHATWG) to extract GitHub repository owner and name. Includes a custom issue filter for CSSWG drafts.

```javascript
// fetch-data/group-repos.js
const fs = require('fs'),
      config = require('../config.json'),
      ghrequest = require('gh-api-request');

ghrequest.ghToken = config.ghapitoken;
ghrequest.userAgent = 'W3C spec dashboard https://github.com/w3c/spec-dashboard';

// URL parser to extract GitHub repo from editor's draft URL
const urlToGHRepo = (url = "", tr_shortname) => {
  const nofilter = x => true;
  const versionless = s => s.replace(/-[0-9]*$/,'');

  // GitHub Pages pattern: https://user.github.io/repo/
  const githubio = url.match(/^https?:\/\/([^\.]*)\.github\.io\/([^\/]*)\/?/);
  if (githubio) {
    return {owner: githubio[1], name: githubio[2], issuefilter: nofilter};
  }

  // CSSWG drafts pattern: https://drafts.csswg.org/css-foo/
  const csswg = url.match(/^https?:\/\/drafts.csswg.org\/([^\/]*)\/?/);
  if (csswg) {
    const cssIssueFilter = shortname => x =>
      x.title.match(new RegExp("\^\[" + versionless(shortname) + "\]"));
    return {owner: 'w3c', name: 'csswg-drafts', issuefilter: cssIssueFilter(csswg[1])};
  }

  // WHATWG pattern: https://foo.spec.whatwg.org/
  const whatwg = url.match(/https:\/\/([^\.]*).spec.whatwg.org\//);
  if (whatwg) {
    return {owner: "whatwg", name: whatwg[1], issuefilter: nofilter};
  }

  return undefined;
};

// Run with: node fetch-data/group-repos.js
// Run with issues update: node fetch-data/group-repos.js --update-issues
// Output: pergroup/32061-repo.json, etc.

```

### Filter Active W3C Specifications

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Filters W3C specifications to include only active ones, excluding 'Retired', 'Discontinued', 'Group Note', or 'Recommendation' statuses. Requires the 'node-w3capi' library.

```javascript
// lib/active-specs.js
const w3c = require('node-w3capi'),
      utils = require('./utils');

const relevantSpecStatus = status =>
  !['Retired', 'Discontinued', 'Group Note', 'Recommendation'].includes(status);

module.exports = async function(wgshortname, cb) {
  const specs = await w3c.group(wgshortname).specifications().fetch({embed: true});

  // Filter: not superseded and not finished
  const unfinishedSpecs = specs.filter(s =>
    s._links &&
    !s._links['superseded-by'] &&
    relevantSpecStatus(s._links['latest-version'].title)
  ).sort((s1, s2) =>
    shortNamer(s1.shortlink).localeCompare(shortNamer(s2.shortlink))
  );

  return unfinishedSpecs;
};

// Usage:
// const activespecs = require('./lib/active-specs');
// const specs = await activespecs({shortname: 'css', type: 'wg'});
// Returns array of active CSS Working Group specifications

```

### W3C Specification Health Report Generator

Source: https://context7.com/w3c/spec-dashboard/llms.txt

Generates health reports for W3C specifications, identifying issues like late CR Snapshots, abandoned specs, long-running specs, and those without known repositories. Fetches data from 'groups.json' and per-group JSON files.

```javascript
// report.js - Health report generation
const monthFromNow = (n) => new Date(new Date().setMonth(new Date().getMonth() + n));

fetchJSON("groups.json")
  .then(groups => {
    return Promise.all(Object.keys(groups).map(gid => {
      const specDataPromise = fetchJSON("./pergroup/" + gid + ".json");
      const repoDataPromise = fetchJSON("./pergroup/" + gid + "-repo.json");

      return Promise.all([specDataPromise, repoDataPromise])
        .then(([specData, repoData]) => {
          // Count specs
          count.textContent = parseInt(count.textContent, 10) + specData.length;

          // Identify problem specs
          Object.values(specData).filter(s => s.versions[0]["rec-track"]).forEach(spec => {
            // Late CR Snapshot: CRD published >24 months after last CRS
            if (spec.versions[0].status === "Candidate Recommendation Draft") {
              const crs = spec.versions.find(v => v.status === "Candidate Recommendation Snapshot");
              if (new Date(crs.date) < monthFrom(-24, new Date(spec.versions[0].date))) {
                lateCRSnapshot.appendChild(specLink(spec));
              }
            }

            // Abandoned: no update in >36 months
            if (new Date(spec.versions[0].date) < monthFromNow(-36)) {
              abandoned.appendChild(specLink(spec));
            }

            // Long-running: FPWD >60 months ago
            if (new Date(last(spec.versions).date) < monthFromNow(-60)) {
              longRunning.appendChild(specLink(spec));
            }

            // No known repo
            if (!repoData[spec.shortlink]) {
              noRepo.appendChild(specLink(spec));
            }
          });
        });
    }));
  });

// Access at: report.html
// Shows categorized lists of specs needing attention
