Data and third-party provenance

This file records what can be established from repository contents and history. It does not assign a license to original strans source code.

Input maps and dictionaries

map/hira.map, map/kata.map, and the original map data entered the history in commit cc157c0b3c33506d1cbf5bd251ddc6a9ca909081, whose subject says the maps came from 9front. That commit does not identify a 9front revision or carry a separate data license. map/telex.map is generated by map/mktelex.py; Vietnamese behavior is retained for compatibility.

map/emoji.dict is generated deterministically from the repository-maintained map/emoji.src by map/mkemoji. No external dataset is required.

map/hanja.src is a single-character subset of libhangul's data/hanja/hanja.txt from release tag libhangul-0.2.0. Its immutable identifiers are:

map/libhangul2hanja keeps only a one-syllable modern Hangul reading paired with one BMP Hanja rune supported by the popup. It writes one Hanja<TAB>Hangul syllable pair per row in upstream order; word entries are not part of this data. map/mkhanja groups those rows by reading for the runtime dictionary without changing candidate order, retaining the first 32 candidates supported by the engine. Exact import and regeneration commands are in map/README.

map/kanji.dict identifies itself as SKK Medium dictionary version 8.1, May 24, 1995, rearranged for Plan 9 ktrans by Kenji Okamoto on February 17, 2000. Its header names its copyright holders and grants GPL version 2 or later. The complete GPL version 2 text is in LICENSES/GPL-2.0-or-later.txt; the dictionary header supplies the "or later" option. map/README records the exact repository history, repairs made to this copy, and the reproducible procedure for importing a new SKK revision.

Fonts

The popup bundles Noto Sans, Japanese-region Noto Sans Mono CJK, and Noto Emoji. Exact checksums, versions or source revisions, download locations where known, fallback order, and license-file names are recorded in font/PROVENANCE. The corresponding OFL 1.1 and Apache 2.0 texts are kept beside the fonts.

stb_truetype

stb_truetype.h is Sean Barrett's stb_truetype version 1.26, dated August 28, 2021 in its header. Its exact repository checksum is:

ecd30b05e0dd4fea3a13c26810dd9e1992dc379049482c393d5a19e6b5090aab

The file was present in the repository's first commit, dcd1147638f908eca7e4b7616815e215022cc99d. No upstream commit or download URL was recorded. Its complete dual MIT/Public Domain terms are retained at the end of the header.

Generated Wayland protocol code

The four checked-in Wayland protocol C/header files were added in commit 7629ec5fe8976812655c9d12b447a62abc8bb671:

input-method-unstable-v2-client-protocol.h
input-method-unstable-v2-protocol.c
virtual-keyboard-unstable-v1-client-protocol.h
virtual-keyboard-unstable-v1-protocol.c

Their embedded notices identify the protocols as input-method-unstable-v2 and virtual-keyboard-unstable-v1 and include the applicable MIT-style license terms. The input-method files report generation by wayland-scanner 1.21.0; the virtual-keyboard files report wayland-scanner 1.23.1. The source XML files and their upstream repository revisions were not committed or recorded in history, so these generated files cannot honestly be regenerated byte-for-byte from repository artifacts. Do not edit them manually. A future regeneration should commit the source XML or record its immutable upstream revision and the scanner command/version.

Git submodules

cutest is pinned by the repository as the unit-test framework. XIM uses the system xcb-imdkit and xcb-util libraries at build time; those system libraries are not bundled by this repository.
