From 2f7fe1189c804d9f1b2f8ce9cda2fccea639950e Mon Sep 17 00:00:00 2001 From: Per Bothner Date: Tue, 16 May 2023 18:31:31 -0700 Subject: [PATCH 01/42] New unicode-graphemes addon. Handle grapheme cluster lookup as well as wcwidth. This is based on Unicode 15, and could replace the unicode11 addon. --- .../xterm-addon-unicode-graphemes/.gitignore | 2 + .../xterm-addon-unicode-graphemes/.npmignore | 29 ++ addons/xterm-addon-unicode-graphemes/LICENSE | 19 + .../xterm-addon-unicode-graphemes/README.md | 25 ++ .../package.json | 26 ++ .../src/UnicodeGraphemeProvider.ts | 44 ++ .../src/UnicodeGraphemesAddon.ts | 17 + .../src/UnicodeProperties.ts | 144 +++++++ .../src/tiny-inflate.ts | 380 ++++++++++++++++++ .../src/tsconfig.json | 33 ++ .../src/unicode-trie.ts | 134 ++++++ .../tsconfig.json | 8 + .../typings/xterm-addon-unicode11.d.ts | 14 + .../webpack.config.js | 38 ++ .../xterm-addon-unicode11/src/UnicodeV11.ts | 24 +- src/common/InputHandler.ts | 73 ++-- src/common/TestUtils.test.ts | 10 +- src/common/Types.d.ts | 2 +- src/common/buffer/BufferLine.test.ts | 6 +- src/common/buffer/BufferLine.ts | 8 +- src/common/input/UnicodeV6.ts | 24 +- src/common/parser/EscapeSequenceParser.ts | 3 + src/common/services/Services.ts | 14 +- src/common/services/UnicodeService.test.ts | 3 + src/common/services/UnicodeService.ts | 21 +- tsconfig.all.json | 1 + typings/xterm-headless.d.ts | 1 + typings/xterm.d.ts | 1 + 28 files changed, 1055 insertions(+), 49 deletions(-) create mode 100644 addons/xterm-addon-unicode-graphemes/.gitignore create mode 100644 addons/xterm-addon-unicode-graphemes/.npmignore create mode 100644 addons/xterm-addon-unicode-graphemes/LICENSE create mode 100644 addons/xterm-addon-unicode-graphemes/README.md create mode 100644 addons/xterm-addon-unicode-graphemes/package.json create mode 100644 addons/xterm-addon-unicode-graphemes/src/UnicodeGraphemeProvider.ts create mode 100644 addons/xterm-addon-unicode-graphemes/src/UnicodeGraphemesAddon.ts create mode 100644 addons/xterm-addon-unicode-graphemes/src/UnicodeProperties.ts create mode 100644 addons/xterm-addon-unicode-graphemes/src/tiny-inflate.ts create mode 100644 addons/xterm-addon-unicode-graphemes/src/tsconfig.json create mode 100644 addons/xterm-addon-unicode-graphemes/src/unicode-trie.ts create mode 100644 addons/xterm-addon-unicode-graphemes/tsconfig.json create mode 100644 addons/xterm-addon-unicode-graphemes/typings/xterm-addon-unicode11.d.ts create mode 100644 addons/xterm-addon-unicode-graphemes/webpack.config.js diff --git a/addons/xterm-addon-unicode-graphemes/.gitignore b/addons/xterm-addon-unicode-graphemes/.gitignore new file mode 100644 index 0000000000..3063f07d55 --- /dev/null +++ b/addons/xterm-addon-unicode-graphemes/.gitignore @@ -0,0 +1,2 @@ +lib +node_modules diff --git a/addons/xterm-addon-unicode-graphemes/.npmignore b/addons/xterm-addon-unicode-graphemes/.npmignore new file mode 100644 index 0000000000..b203232aff --- /dev/null +++ b/addons/xterm-addon-unicode-graphemes/.npmignore @@ -0,0 +1,29 @@ +# Blacklist - exclude everything except npm defaults such as LICENSE, etc +* +!*/ + +# Whitelist - lib/ +!lib/**/*.d.ts + +!lib/**/*.js +!lib/**/*.js.map + +!lib/**/*.css + +# Whitelist - src/ +!src/**/*.ts +!src/**/*.d.ts + +!src/**/*.js +!src/**/*.js.map + +!src/**/*.css + +# Blacklist - src/ test files +src/**/*.test.ts +src/**/*.test.d.ts +src/**/*.test.js +src/**/*.test.js.map + +# Whitelist - typings/ +!typings/*.d.ts diff --git a/addons/xterm-addon-unicode-graphemes/LICENSE b/addons/xterm-addon-unicode-graphemes/LICENSE new file mode 100644 index 0000000000..8f17892587 --- /dev/null +++ b/addons/xterm-addon-unicode-graphemes/LICENSE @@ -0,0 +1,19 @@ +Copyright (c) 2019, The xterm.js authors (https://github.com/xtermjs/xterm.js) + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
