I won't go into the minor details of the theme building process, however I will talk about the high level details of what is accomplished.
All themes have a base template that they inherit from. Themes have the ability to choose their inherited parent. Each child has the ability to override any attributes defined by the parent. This mitigates any one-off issues for themes that are not captured by the global shared style.
Before you get started, you'll probably want to follow the installation instructions
- Yarn package manager
- Node 14
Set up Yarn Globals
I heavily use Node/Typescript to build all of my themes, and I have a fair amount of global tools installed.
Just run
yarn global add typescript ts-node nodemon
Note: if you already have these globally installed please make sure you are up to date!
yarn global upgrade typescript ts-node
Get the Master Themes
Since this theme suite expands across multiple platforms, in order to maintain consistency of the look and feel across platforms, there is a central theme definition repository
This repository needs to be cloned as a directory called masterThemes
. If you are running Linux/MacOS, you can
run getMasterThemes.sh
located at the root of this repository. This script does exactly what is required, if you are
on Windows, have you considered Linux? Just kidding (mostly), you'll need to run this command
git clone https://github.com/doki-theme/doki-master-theme.git masterThemes
Your directory structure should have at least these directories, (there will probably be more, but these are the important ones to know).
your-workspace/
├─ doki-theme-github/
│ ├─ masterThemes/
│ ├─ buildSrc/
Inside the masterThemes
directory, you'll want to make sure all the dependencies are available to the build scripts.
To accomplish this, just run this command in the masterThemes
directory.
yarn
Navigate to the root of the buildSource
directory and run the following command.
yarn
This will install all the required dependencies to run the theme build process.
You should be good to edit and add themes after that!
I have too many themes to maintain manually, so theme creation/maintenance is automated and shared common parts to reduce overhead.
The standardized approach used by all the plugins supporting the Doki Theme suite, is that there is a buildSrc
directory.
Inside the buildSrc
directory, there will be 2 directories:
src
- holds the code that builds the themes.assets
- defines the platform specific assets needed to build the themes. This directory normally contains two child directories.themes
- holds the application definitionstemplates
- if not empty, normally contains various text files that can be evaluated to replace variables with values. Some cases, they also contain templates for evaluating things such as look and feel, colors, and other things.
The buildSrc
directory houses a buildThemes
script that generates the application specific files necessary for apply
the Doki Theme Suite.
There is one file that is important, it can be found in buildSrc/assets/templates
. That file is tempCss.css.txt, which
is the template for the common user CSS that used for all themes.
This template is evaluated as part of the theme building process. When you run this command in the buildSrc
directory:
yarn buildThemes
This template will be evaluated for each theme and be placed in the corresponding directory <repo-root>/themes
as
a *.user.css
file.
Some themes have some one-off issues that can be fixed by adding some stuff to the github.definition.json
file. Here
is an example of fixing a
themes primary button
so that the button text is readable.
I haven't figured out a good way to test theme changes, so here's what I do.
- Create a test stylus theme.
- run the
buildThemes
command. - Copy the theme's user.css you are testing.
Import
the theme.- Overwrite the existing theme
- Contemplate life choices
- Repeat until satisfied.
Here is an example of a editing pull request
IMPORTANT! Do not create brand new Doki-Themes using the GitHub Plugin. New themes should be created from the original JetBrains plugin which uses all the colors defined. There is also Doki Theme creation assistance provided by the IDE as well.
Please follow the theme creation contributions in the JetBrains Plugin repository for more details on how to build new themes.
- Follow the initial setup
- You'll also probably want to have completed the Doki Theme VS-Code process. As this plugin uses the sticker assets of the VS-Code plugin. So it helps to have those in place!
Get the assets repository
Clone the doki-theme-assets repository in the same parent directory as this plugin's repository.
Your folder structure should look like this:
your-workspace/
├─ doki-theme-github/
│ ├─ masterThemes/
├─ doki-theme-assets/
This part is mostly automated, for the most part. There is only one script you'll need to run.
Once you have a new master theme definitions merged into the default branch, it's now time to generate the application specific templates, which allow us to control individual theme specific settings.
You'll want to edit the function used by buildApplicationTemplate
and appName
defined here
in your masterThemes
directory.
In the case of this plugin the buildApplicationsTemplate
should use the githubTemplate
and appName
should
be github
.
We need run the generateTemplates
script. Which will walk the master theme definitions and create the new templates in
the <repo-root>/buildSrc/assets/themes
directory (and update existing ones). In
the <your-workspace>/doki-theme-github/masterThemes
run this command:
yarn generateTemplates
The code defined in the buildSrc/src
directory is part of the common Doki Theme construction suite. All other plugins
work the same way, just some details change for each plugin, looking at
you doki-theme-web. This group of code exposes a buildThemes
node
script.
This script does all the annoying tedious stuff such as:
- Evaluating the
buildSrc/assets/templates
from the templates and putting the user.css in the right place. See GitHub Specifics for more details.
Because of silly cross-origin "safety" precautions taken by GitHub (or stylus, I forget), I can't use the assets
from https://doki.assets.unthrottled.io. So to get around that, the GitHub user
css, uses assets from the same parent domain. So I wrote a script that forklifts the assets, plus the expected directory
structure into the doki-theme-github/assets
directory automatically (if it doesn't exist, will not overwrite). In
the doki-theme-github/buildSrc
directory run:
yarn copyAssets
Note: you'll probably want to update the sticker's url in the tempUserCss.css.txt file to point to the branch/repo you are working on. Be sure to change it back before submitting a PR!
Here is an example pull request that captures all the artifacts from the development process of imported themes . There is going to be a heckin a lot of changes, so be prepared!
