## Prerequisites
|
|
|
|
Follow the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of `Ruby`, `RubyGems`, `Jekyll` and `Bundler`. Please note that the version of `Ruby` must meet the requirements of the theme on [RubyGems.org](https://rubygems.org/gems/jekyll-theme-chirpy).
|
|
|
|
## Installation
|
|
|
|
There are two ways to get the theme:
|
|
|
|
- **[Install from RubyGems](#install-from-rubygems)** - Easy to update, isolate irrelevant project files so you can focus on writing.
|
|
- **[Fork on GitHub](#fork-on-github)** - Convenient for custom development, but difficult to update, only suitable for web developers.
|
|
|
|
### Install from RubyGems
|
|
|
|
Add this line to your Jekyll site's `Gemfile`:
|
|
|
|
```ruby
|
|
gem "jekyll-theme-chirpy"
|
|
```
|
|
{: .nolineno}
|
|
|
|
And add this line to your Jekyll site's `_config.yml`:
|
|
|
|
```yaml
|
|
theme: jekyll-theme-chirpy
|
|
```
|
|
{: .nolineno}
|
|
|
|
And then execute:
|
|
|
|
```console
|
|
$ bundle
|
|
```
|
|
|
|
Next, go to the installed local theme path:
|
|
|
|
```console
|
|
$ cd "$(bundle info --path jekyll-theme-chirpy)"
|
|
```
|
|
|
|
And then copy the critical files (for details, see [starter project][starter]) from the theme's gem to your Jekyll site.
|
|
|
|
> ⚠️ **Watch out for duplicate files!**
|
|
>
|
|
> If your Jekyll site is created by the `jekyll new` command, there will be `index.markdown` and `about.markdown` in the root directory of your site. Please be sure to remove them, otherwise they will overwrite the `index.html` and `_tabs/about.html` from this project, resulting in blank or messy pages.
|
|
|
|
As an alternative, which we recommend, you can create a Jekyll site [**using the starter template**][use-starter] to save time copying files from the theme's gem. We've prepared everything you need there!
|
|
|
|
### Fork on GitHub
|
|
|
|
[Fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork) on GitHub and then clone your fork to local. (Please note that the default branch code is in development. If you want the blog to be stable, please switch to the [latest tag](https://github.com/cotes2020/jekyll-theme-chirpy/tags) and start writing.)
|
|
|
|
Install gem dependencies by:
|
|
|
|
```console
|
|
$ bundle
|
|
```
|
|
|
|
And then execute:
|
|
|
|
```console
|
|
$ bash tools/init.sh
|
|
```
|
|
|
|
> **Note**: If you don't plan to deploy your site on GitHub Pages, append parameter option `--no-gh` at the end of the above command.
|
|
|
|
What it does is:
|
|
|
|
1. Remove some files or directories from your repository:
|
|
- `.travis.yml`
|
|
- files under `_posts`
|
|
- folder `docs`
|
|
|
|
2. If you use the `--no-gh` option, the directory `.github` will be deleted. Otherwise, setup 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. Automatically create a commit to save the changes.
|
|
|
|
## 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 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`, 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:
|
|
|
|
```terminal
|
|
$ docker run -it --rm \
|
|
--volume="$PWD:/srv/jekyll" \
|
|
-p 4000:4000 jekyll/jekyll \
|
|
jekyll serve
|
|
```
|
|
|
|
Open a browser and visit to _<http://localhost:4000>_.
|
|
|
|
### Deployment
|
|
|
|
Before the deployment begins, checkout 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 starting with a slash, e.g, `/project-name`.
|
|
|
|
Now you can choose ONE of the following methods to deploy your Jekyll site.
|
|
|
|
#### Deploy on GitHub Pages
|
|
|
|
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 GH 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 [workflow 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/test.sh` and `tools/deploy.sh`. Otherwise, copy them from this repo to your Jekyll site.
|
|
|
|
And then 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 repo's landing page on GitHub and select the branch `gh-pages` as the [publishing source](https://docs.github.com/en/github/working-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site) through _Settings_ → _Options_ → _GitHub Pages_:
|
|
|
|
{: width="850" height="153" }
|
|
|
|
3. Visit your website at the address indicated by GitHub.
|
|
|
|
#### Deploy on Other Platforms
|
|
|
|
On platforms other than GitHub, we cannot enjoy the convenience of **GitHub Actions**. Therefore, we should build the site locally (or on some other 3rd-party CI platform) and then put the site files on the server.
|
|
|
|
Go to the root of the source project, build your site by:
|
|
|
|
```console
|
|
$ JEKYLL_ENV=production bundle exec jekyll b
|
|
```
|
|
|
|
Or build the site with Docker by:
|
|
|
|
```terminal
|
|
$ 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 your web server.
