## Prerequisites
|
|
|
|
Follow the instructions in the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of the basic environment. [Git](https://git-scm.com/) also needs to be installed.
|
|
|
|
## 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
|
|
|
|
Sign in to GitHub and browse to [**Chirpy Starter**](https://github.com/cotes2020/chirpy-starter/), click the button <kbd>Use this template</kbd> > <kbd>Create a new repository</kbd>, and name the new repository `USERNAME.github.io`, where `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 `USERNAME.github.io`. Note that the default branch code is under development. To ensure the stability of your site, please switch to the [latest tag][latest-tag] and start writing.
|
|
|
|
And then execute:
|
|
|
|
```console
|
|
$ bash tools/init
|
|
```
|
|
|
|
> If you don't want to deploy your site on GitHub Pages, append option `--no-gh` at the end of the above command.
|
|
{: .prompt-info }
|
|
|
|
The above command will:
|
|
|
|
1. Remove the files in `_posts`{: .filepath} from your repository.
|
|
|
|
2. If the option `--no-gh` is provided, the directory `.github`{: .filepath} will be deleted. Otherwise, set up the GitHub Action workflow by removing the extension `.hook`{: .filepath} of `.github/workflows/pages-deploy.yml.hook`{: .filepath}, and then remove the other files and directories in the folder `.github`{: .filepath}.
|
|
|
|
3. Create 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`{: .filepath} as needed. Some of them are typical options:
|
|
|
|
- `url`
|
|
- `avatar`
|
|
- `timezone`
|
|
- `lang`
|
|
|
|
### Customizing Stylesheet
|
|
|
|
If you need to customize the stylesheet, copy the theme's `assets/css/style.scss`{: .filepath} to the same path on your Jekyll site, and then add the custom style at the end of it.
|
|
|
|
Starting with version `4.1.0`, if you want to overwrite the SASS variables defined in `_sass/addon/variables.scss`{: .filepath}, copy the main sass file `_sass/jekyll-theme-chirpy.scss`{: .filepath} into the `_sass`{: .filepath} directory in your site's source, then create a new file `_sass/variables-hook.scss`{: .filepath} and assign new value.
|
|
|
|
### Customing Static Assets
|
|
|
|
Static assets configuration was introduced in version `5.1.0`. The CDN of the static assets is defined by file `_data/assets/cross_origin.yml`{: .filepath }, and you can replace some of them according to the network conditions in the region where your website is published.
|
|
|
|
Also, if you'd like to self-host the static assets, please refer to the [_chirpy-static-assets_](https://github.com/cotes2020/chirpy-static-assets#readme).
|
|
|
|
### 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 few seconds, the local service will be published at _<http://127.0.0.1:4000>_.
|
|
|
|
## Deployment
|
|
|
|
Before the deployment begins, check out the file `_config.yml`{: .filepath} 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
|
|
|
|
There are a few things to get ready for.
|
|
|
|
- If you're on the GitHub Free plan, keep your site repository public.
|
|
- If you have committed `Gemfile.lock`{: .filepath} to the repository, and your local machine is not running Linux, go the the root of your site and update the platform list of the lock-file:
|
|
|
|
```console
|
|
$ bundle lock --add-platform x86_64-linux
|
|
```
|
|
|
|
Next, configure the _Pages_ service.
|
|
|
|
1. Browse to your repository on GitHub. Select the tab _Settings_, then click _Pages_ in the left navigation bar. Then, in the **Source** section (under _Build and deployment_), select [**GitHub Actions**][pages-workflow-src] from the dropdown menu.
|
|
|
|
2. Push any commits to GitHub to trigger the _Actions_ workflow. In the _Actions_ tab of your repository, you should see the workflow _Build and Deploy_ running. Once the build is complete and successful, the site will be deployed automatically.
|
|
|
|
At this point, you can go to the URL indicated by GitHub to access your site.
|
|
|
|
### 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`{: .filepath} 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`{: .filepath}), editing the `Gemfile`{: .filepath} 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", "~> 4.3", ">= 4.3.2"
|
|
```
|
|
{: .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`{: .filepath} 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.
