Customize

Currently My RIME only distributes IMEs maintained by RIME organization. For ease of maintenance, 3rd party IME integration request is usually not accepted.

However, you are more than welcomed to host a customized version of My RIME to distribute 3rd party IME.

Prerequisite

Your IME must work on Linux/Windows/macOS.
- If your IME works on desktop but doesn't work as expected when you port it to web, it may be the result of My RIME not fully utilizing librime functionalities, so I'm glad to help you resolve.
Your IME should be plum compatible, otherwise you have to customize build script yourself.

Step

Clone the repo. Do not use --recurse-submodules.
Replicate build steps locally. You may reference README, Dockerfile or build job of CI script. Those steps work on Ubuntu latest stable and LTS release. It's highly recommended to be done BEFORE your customization, in order to locate problems.
Customize schemas.json.
If your IME has *.custom.yaml, place them under rime-config.
Run pnpm run schema.
Run pnpm run wasm (given pnpm run lib has already been executed).
Test by pnpm run dev.
Once everything works fine, run pnpm run build.
The artifact is in dist, and you may deploy it to a static web server.

Specification

schemas.json is a list of objects. An IME corresponds to a schema id.

IMEs in different plum-compatible repositories should be placed in different objects, e.g. luna_pinyin (in luna-pinyin) and jyut6ping3 (in cantonese), although there's a reverse-lookup dependency between them.
IMEs in one repository should be placed in one object if they share variant configurations, e.g. luna_pinyin and luna_pinyin_fluency both have 简 and 繁.
IMEs in one repository should be placed in different objects if they don't share variant configurations, e.g. you have both luna_pinyin and melt_eng.

For each object, here are key and value definitions:

id: string, the schema id that you place in default.yaml for desktop RIME.
name: string, the label you want to show as IME name for user to select.
disabled?: boolean, whether the IME is only used for reverse-lookup by other IMEs so you don't want to show it in select. Default false.
group?: string, group of the IME. Default undefined.
emoji?: boolean, whether integrate emoji. Default false.
target: string, the same argument you use when installing by plum: bash rime-install <target>.
dependencies?: string[], schema ids that are either a hard dependency (e.g. luna_pinyin for double_pinyin) or a soft (required by reverse-lookup) dependency (e.g. stroke for luna_pinyin). Make sure you have them defined in other objects. Default [].
variants?: object[], simplified/traditional/... variants. Default undefined means the table is traditional, and simplified variant is available by OpenCC using simplification option, and you want simplified variant be the default variant unless browser's locale is Hong Kong or Taiwan, e.g. luna_pinyin. An empty [] means there are no variants and the variant switch button is disabled, e.g. stroke.
- id: string, the corresponding option in .schema.yaml.
- name: string, the label you want to show on the switch button.
- languages?: ('zh-CN' | 'zh-HK' | 'zh-TW' | 'zh-SG')[], if browser's locale is in the list, use this variant by default.
The first variant will be the default variant, regardless what default value is in .schema.yaml. Switching to a variant will first set other options to 0, and then set this variant's option to 1. So if there is only one option that controls 2 variants, you may use [{"id": "option"}, {"id": "random stuff"}] if the default variant should have option on, and [{"id": "random stuff"}, {"id": "option"}] if the default variant should have option off. If you can understand this, you should agree that undefined is equivalent to [{"id": "simplification", "name": "简"}, {"id": "233", "name": "繁", "languages": ["zh-HK", "zh-TW"]}].
extended?: boolean, whether the .schema.yaml supports common/extended charset switch. Default false.
hideComment?: boolean | 'emoji', whether hide comment after candidate. 'emoji' means only hide comment after emoji candidate. Default false.
family?: object[], the other IMEs that share some files. Each shares the same variants with the major IME. Default [].
- id: string, the schema id.
- name: string, the label.
- disabled?: boolean, same with the disabled in parent level.
license: string, a SPDX license identifier used in package.json.

Distribute

As per LICENSE requires, you have to

Adopt the same AGPL license to your distribution.
Include my copyright. The easiest way to comply is to put a link to https://github.com/LibreService/my_rime in your site.

if you distribute it to a public-accessible site.

You are not required, but welcomed to make your IME (*.schema.yaml, *.dict.yaml, *.lua) Open Source and plum compatible.
