# `stratic-truncate-indexes`

Gulp plugin to truncate Stratic indexes to a specific number of posts

This is particularly useful in combination with stratic-indexes-to-rss.

Installation

npm install stratic-truncate-indexes

Usage

All you need to do is pipe Stratic indexes to this module and BAM! It'll truncate them to a certain number of posts - 15 by default.

You may also pass a number to the module to override the number of posts to truncate to. The complete example below shows this.

Examples

Minimal gulpfile.js for this module to work:

var gulp = require('gulp');
var frontmatter = require('gulp-gray-matter');
var straticDateInPath = require('stratic-date-in-path');
var addsrc = require('gulp-add-src');
var straticPostsToIndex = require('stratic-posts-to-index');
var straticTruncateIndexes = require('stratic-truncate-indexes');

gulp.task('rss', function() {
    gulp.src('*.md')
        .pipe(frontmatter())
        .pipe(straticDateInPath())
        .pipe(addsrc('src/blog/index.jade'))
        .pipe(straticPostsToIndex('index.jade'))
        .pipe(straticTruncateIndexes());
});

Complete example gulpfile.js:

var gulp = require('gulp');
var frontmatter = require('gulp-gray-matter');
var remark = require('gulp-remark');
var remarkHtml = require('remark-html');
var straticDateInPath = require('stratic-date-in-path');
var addsrc = require('gulp-add-src');
var straticPostsToIndex = require('stratic-posts-to-index');
var straticTruncateIndexes = require('stratic-truncate-indexes');
var straticIndexesToRss = require('stratic-indexes-to-rss');
var rename = require('gulp-rename');

gulp.task('rss', function() {
    gulp.src('*.md')
        .pipe(frontmatter())
        .pipe(remark().use(remarkHtml))
        .pipe(straticDateInPath())
        .pipe(addsrc('src/blog/index.jade'))
        .pipe(straticPostsToIndex('index.jade'))
        .pipe(straticTruncateIndexes(10)) // Override the default number of posts to truncate to
        .pipe(straticIndexesToRss({title: 'Blag!'}, 'https://example.com/blog/'))
        .pipe(rename({ extname: '.rss' }))
        .pipe(gulp.dest('dist/blog'));
});
