Summary by CodeRabbit

  • New Features

    • Added a configuration option to enable or disable learning behavior.
    • Learning is automatically skipped for password fields and other sensitive input.
  • Bug Fixes

    • Disabled learning no longer adds words to personal history or the user dictionary.
    • Cloud-selected words now consistently follow learning preferences before being saved.
    • Learning behavior is applied consistently across dictionary and history updates.

Changes

The Pinyin engine adds configurable learning. Learning requires enabled configuration and excludes sensitive input contexts. Cloud pinyin selection continues required parsing while gating dictionary, logging, and history updates.

Pinyin learning control

Layer / File(s) Summary
Learning policy and context gating
im/pinyin/pinyin.h, im/pinyin/pinyin.cpp
The engine adds the learning option with a default of true. shouldLearn checks this option and rejects PasswordOrSensitive contexts. updateUI uses the helper.
Cloud selection learning integration
im/pinyin/pinyin.cpp
cloudPinyinSelected computes the learning decision before processing. It keeps required word parsing and words construction independent from dictionary, logging, and history updates.

This is too deep, should stop much earlier.

Tested "wo ui vo yj de xx na". First select "我是", then select cloud candidate "灼眼的夏娜". The initial value of words is

(我, WK), (是, QN)

while after the do-while block it becomes

(我, WK), (是, QN), (灼眼的夏娜, OZVCEFNOGA)

and may still be used at keepContext or prediction. So early stop only makes sense when all these 3 conditions are false.

2481-2483: 🎯 Functional Correctness | 🟡 Minor

Do not exit before validating and building words.

When Learning is disabled, this break skips preedit validation and the append for the selected cloud word. The code after the loop still uses words for current-context preservation and prediction, so the selected cloud word is omitted from both. If the callback uses stale context, the unconditional commit can also accept the stale selection without validation.

Keep parsing and words construction unconditional. Guard only user-dictionary, history, and learning-only logging writes with shouldLearn.
