# 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/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:

```text
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.
