gulp-version-tool

Replaces strings in files by using string or regex patterns. Works with Gulp 3!

Usage

npm install gulp-version-tool --save-dev

Plays well in your gulptask file.

const gulp = require ("gulp");
const runSequence = require ("run-sequence"); // Run tasks sequentially
const jsEditor = require ("gulp-version-tool/src/json_edit");
const replace = require ("gulp-version-tool/src/replace");
const versionPump = require ("gulp-version-tool/src/version_pump");
gulp.task ("upversion", function () {
    let ver = require ("./package.json").version;
    //version defined in the package.json file
    console.log ("current version: ", ver);
    process.env.VERSION = versionPump (ver);
    console.log (process.env.VERSION);
});
gulp.task ("saveversion", function () {
    return gulp.src ("./package.json")
        .pipe (jsEditor (function (json) {
            json.version = process.env.VERSION;
            return json; // must return JSON object.
        }))
        .pipe (gulp.dest ("."));

});
gulp.task ("version_up", function () {
    gulp.src (["./example/version.ts"])
        .pipe (replace (/(\d+)\.(\d+)(?:\.(\d+))?(?:\-(\w+))?/, process.env.VERSION))
        .pipe (gulp.dest ("./example/newv"))
});
gulp.task ("autoversion", function () {
    // runSequence ("upversion", "version_up", "saveversion");
    runSequence ("upversion", "version_up", "saveversion");
});

Regex Replace

var replace = require("gulp-version-tool/src/replace");
var json_ed = require("gulp-version-tool/src/json_edit");
gulp.task("replace_1", function() {
  gulp.src(["./config.js"]) // Any file globs are supported
    .pipe(replace(new RegExp("@env@", "g"), "production"))
    .pipe(gulp.dest("./build/config.js"))
});

gulp.task("replace_2", function() {
  gulp.src(["./index.html"])
    .pipe(replace(/version(={1})/g, "$1v0.2.2"))
    .pipe(gulp.dest("./build/index.html"))
});

gulp.task("replace_3", function() {
  gulp.src(["./config.js"])
    .pipe(replace(/foo/g, function () {
        return "bar";
    }))
    .pipe(gulp.dest("./build/config.js"))
});

String Replace

gulp.task("replace_1", function() {
  gulp.src(["./config.js"])
    .pipe(replace("environment", "production"))
    .pipe(gulp.dest("./build/config.js"))
});

Function Replace

gulp.task("replace_1", function() {
  gulp.src(["./config.js"])
    .pipe(replace("environment", function () {
        return "production";
    }))
    .pipe(gulp.dest("./build/config.js"))
});

gulp.task("replace_2", function() {
  gulp.src(["./config.js"])
    .pipe(replace("environment", function (replacement) {
        return replacement + "_mocked";
    }))
    .pipe(gulp.dest("./build/config.js"))
});

Exampe with options object

var options = {
  logs: {
    enabled: false
  }
};

gulp.task("replace_1", function() {
  gulp.src(["./config.js"])
    .pipe(replace("environment", "dev", options)
    .pipe(gulp.dest("./build/config.js"))
});
