## Prerequisites
|
|
|
|
Follow the instructions in the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of `Ruby`, `RubyGems`, `Jekyll`, and `Bundler`.
|
|
|
|
## Installation
|
|
|
|
### Creating a New Site
|
|
|
|
There are two ways to create a new repository for this theme:
|
|
|
|
- [**Using the Chirpy Starter**](#option-1-using-the-chirpy-starter) - Easy to upgrade, isolates irrelevant project files so you can focus on writing.
|
|
- [**Forking on GitHub**](#option-2-forking-on-github) - Convenient for custom development, but difficult to upgrade. Unless you are familiar with Jekyll and are determined to tweak or contribute to this project, this approach is not recommended.
|
|
|
|
#### Option 1. Using the Chirpy Starter
|
|
|
|
Create a new repository from the [**Chirpy Starter**][use-starter] and name it `<GH_USERNAME>.github.io`, where `GH_USERNAME` represents your GitHub username.
|
|
|
|
#### Option 2. Forking on GitHub
|
|
|
|
[Fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork) on GitHub and rename it to `<GH_USERNAME>.github.io`. Please note that the default branch code is in development. If you want the site to be stable, please switch to the [latest tag][latest-tag] and start writing.
|
|
|
|
And then execute:
|
|
|
|
```console
|
|
$ bash tools/init.sh
|
|
```
|
|
|
|
> **Note**: If you don't want to deploy your site on GitHub Pages, append option `--no-gh` at the end of the above command.
|
|
|
|
The above command will:
|
|
|
|
1. Removes some files or directories from your repository:
|
|
- `.travis.yml`
|
|
- files under `_posts`
|
|
- folder `docs`
|
|
|
|
2. If the option `--no-gh` is provided, the directory `.github` will be deleted. Otherwise, set up the GitHub Action workflow by removing the extension `.hook` of `.github/workflows/pages-deploy.yml.hook`, and then remove the other files and directories in the folder `.github`.
|
|
|
|
3. Removes item `Gemfile.lock` from `.gitignore`.
|
|
|
|
4. Creates a new commit to save the changes automatically.
|
|
|
|
### Installing Dependencies
|
|
|
|
Before running for the first time, go to the root directory of your site, and install dependencies as follows:
|
|
|
|
```console
|
|
$ bundle
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Configuration
|
|
|
|
Update the variables of `_config.yml` as needed. Some of them are typical options:
|
|
|
|
- `url`
|
|
- `avatar`
|
|
- `timezone`
|
|
- `lang`
|
|
|
|
### Customing Stylesheet
|
|
|
|
If you need to customize the stylesheet, copy the theme's `assets/css/style.scss` to the same path on your Jekyll site, and then add the custom style at the end of the style file.
|
|
|
|
Starting from [`v4.1.0`][chirpy-4.1.0], if you want to overwrite the SASS variables defined in `_sass/addon/variables.scss`, create a new file `_sass/variables-hook.scss` and assign new values to the target variable in it.
|
|
|
|
### Running Local Server
|
|
|
|
You may want to preview the site contents before publishing, so just run it by:
|
|
|
|
```console
|
|
$ bundle exec jekyll s
|
|
```
|
|
|
|
Or run the site on Docker with the following command:
|
|
|
|
```console
|
|
$ docker run -it --rm \
|
|
--volume="$PWD:/srv/jekyll" \
|
|
-p 4000:4000 jekyll/jekyll \
|
|
jekyll serve
|
|
```
|
|
|
|
After a while, the local service will be published at _<http://127.0.0.1:4000>_.
|
|
|
|
### Deployment
|
|
|
|
Before the deployment begins, check out the file `_config.yml` and make sure the `url` is configured correctly. Furthermore, if you prefer the [**project site**](https://help.github.com/en/github/working-with-github-pages/about-github-pages#types-of-github-pages-sites) and don't use a custom domain, or you want to visit your website with a base URL on a web server other than **GitHub Pages**, remember to change the `baseurl` to your project name that starts with a slash, e.g, `/project-name`.
|
|
|
|
Now you can choose ONE of the following methods to deploy your Jekyll site.
|
|
|
|
#### Deploy by Using Github Actions
|
|
|
|
For security reasons, GitHub Pages build runs on `safe` mode, which restricts us from using plugins to generate additional page files. Therefore, we can use **GitHub Actions** to build the site, store the built site files on a new branch, and use that branch as the source of the GitHub Pages service.
|
|
|
|
Quickly check the files needed for GitHub Actions build:
|
|
|
|
- Ensure your Jekyll site has the file `.github/workflows/pages-deploy.yml`. Otherwise, create a new one and fill in the contents of the [sample file][workflow], and the value of the `on.push.branches` should be the same as your repo's default branch name.
|
|
|
|
- Ensure your Jekyll site has file `tools/deploy.sh`. Otherwise, copy it from here to your Jekyll site.
|
|
|
|
- Furthermore, if you have committed `Gemfile.lock` to the repo, and your runtime system is not Linux, don't forget to update the platform list in the lock file:
|
|
|
|
```console
|
|
$ bundle lock --add-platform x86_64-linux
|
|
```
|
|
|
|
After the above steps, rename your repository to `<GH_USERNAME>.github.io` on GitHub.
|
|
|
|
Now publish your Jekyll site by:
|
|
|
|
1. Push any commit to remote to trigger the GitHub Actions workflow. Once the build is complete and successful, a new remote branch named `gh-pages` will appear to store the built site files.
|
|
|
|
2. Browse to your repository on GitHub. Select the tab _Settings_, then click _Pages_ in the left navigation bar, and then in the section **Source** of _GitHub Pages_, select the `/(root)` directory of branch `gh-pages` as the [publishing source][pages-src]. Remember to click <kbd>Save</kbd> before leaving.
|
|
|
|
{: width="850" height="153" }
|
|
|
|
3. Visit your website at the address indicated by GitHub.
|
|
|
|
#### Manually Build and Deploy
|
|
|
|
On self-hosted servers, you cannot enjoy the convenience of **GitHub Actions**. Therefore, you should build the site on your local machine and then upload the site files to the server.
|
|
|
|
Go to the root of the source project, and build your site as follows:
|
|
|
|
```console
|
|
$ JEKYLL_ENV=production bundle exec jekyll b
|
|
```
|
|
|
|
Or build the site on Docker:
|
|
|
|
```console
|
|
$ docker run -it --rm \
|
|
--env JEKYLL_ENV=production \
|
|
--volume="$PWD:/srv/jekyll" \
|
|
jekyll/jekyll \
|
|
jekyll build
|
|
```
|
|
|
|
Unless you specified the output path, the generated site files will be placed in folder `_site` of the project's root directory. Now you should upload those files to the target server.
|
|
|
|
### Upgrading
|
|
|
|
It depends on how you use the theme:
|
|
|
|
- If you are using the theme gem (there will be `gem "jekyll-theme-chirpy"` in the `Gemfile`), editing the `Gemfile` and update the version number of the theme gem, for example:
|
|
|
|
```diff
|
|
- gem "jekyll-theme-chirpy", "~> 3.2", ">= 3.2.1"
|
|
+ gem "jekyll-theme-chirpy", "~> 3.3", ">= 3.3.0"
|
|
```
|
|
{: .nolineno file="Gemfile" }
|
|
|
|
And then execute the following command:
|
|
|
|
```console
|
|
$ bundle update jekyll-theme-chirpy
|
|
```
|
|
|
|
As the version upgrades, the critical files (for details, see the [Startup Template][starter]) and configuration options will change. Please refer to the [Upgrade Guide](https://github.com/cotes2020/jekyll-theme-chirpy/wiki/Upgrade-Guide) to keep your repo's files in sync with the latest version of the theme.
|
|
|
|
- If you forked from the source project (there will be `gemspec` in the `Gemfile` of your site), then merge the [latest upstream tags][latest-tag] into your Jekyll site to complete the upgrade.
|
|
The merge is likely to conflict with your local modifications. Please be patient and careful to resolve these conflicts.
