AGLFN comprises the set of glyph names from AGL that map via the AGL Specification rules to the semantically correct UV (Unicode Value). For example, \"Asmall\" is omitted because AGL maps this glyph name to the PUA (Private Use Area) value U+F761, rather than to the UV that maps from the glyph name \"A.\" Also omitted is \"ffi,\" because AGL maps this to the Alphabetic Presentation Forms value U+FB03, rather than decomposing it into the following sequence of three UVs: U+0066, U+0066, and U+0069. The name \"arrowvertex\" has been omitted because this glyph now has a real UV, and AGL is now incorrect in mapping it to the PUA value U+F8E6. If you do not find an appropriate name for your glyph in this list, then please refer to Section 6 of the AGL Specification.\n\n\n\nThe ITC Zapf Dingbats Glyph List* is similar to AGL in that it simply provides mappings from glyph names to Unicode scalar values, but only for glyphs in the ITC Zapf Dingbats font.\n\n\n", "file_path": "resources/font/adobe_glyph_list/README.md", "rank": 10, "score": 48985.92950950212 }, { "content": "## Format\n\n\n\nEach record in AGL (glyphlist.txt) and the ITC Zapf Dingbats Glyph List (zapfdingbats.txt) is comprised of two semicolon-delimited fields, described as follows:\n\n\n\n* Glyph name—upper/lowercase letters and digits\n\n* Unicode scalar value—four uppercase hexadecimal digits\n\n\n\nThe AGL and ITC Zapf Dingbats Glyph List records are sorted by glyph name in increasing ASCII order, lines starting with \"#\" are comments, and blank lines should be ignored.\n\n\n\nEach record in AGLFN (aglfn.txt) is comprised of three semicolon-delimited fields, described as follows:\n\n\n\n* Standard UV or CUS (Corporate Use Subarea) UV—four uppercase hexadecimal digits\n\n* Glyph name—upper/lowercase letters and digits\n\n* Character names: Unicode character names for standard UVs, and descriptive names for CUS UVs—uppercase letters, hyphen, and space\n\n\n\nThe AGLFN records are sorted by glyph name in increasing ASCII order, entries with the same glyph name are sorted in decreasing priority order, the UVs and Unicode character names are provided for convenience, lines starting with \"#\" are comments, and blank lines should be ignored.\n\n\n\n## More Information\n\n\n\nImportant details about glyph naming and interpreting glyph names can be found in the [AGL Specification](https://github.com/adobe-type-tools/agl-specification), which is an open specification.\n\n\n\nThe tools and documentation that comprise [AFDKO (Adobe Font Development Kit for OpenType)](http://www.adobe.com/devnet/opentype/afdko.html) are helpful for those who develop OpenType fonts.

Components can be enabled or disabled by including or removing/commenting out the relevant section of configuration. An example configuration file is included in [example_config.toml](example_config.toml).\n\n\n\nA configuration file can either be specified as the first argument to `rust-motd` via the comnmand line or placed in one of two default locations. If a config file is not specified as an argument, `rust-motd` will check `$XDG_CONFIG_HOME/rust-motd/config.toml` and `$HOME/.config/rust-motd/config.toml` in that order.\n\n\n\nThe options for each component are listed below:\n\n### Banner\n\n\n\n- `color`: The color of the banner text. Options are black, red, green, yellow, blue, magenta, cyan, white, and light variants of each.\n\n- `command`: A command executed via `sh` which generates the banner. For example, you could pipe the output of `hostname` to `figlet` to generate a block letter banner.\n\n\n\n### Weather\n\n\n\nThe weather component allows you to either specify a [wttr.in](https://wttr.in) url, or a location and display style which will be used to build the url.\n\n\n\nEither:\n\n\n\n- `url`: a [wttr.in](https://wttr.in) query url for the relevant location. E.g. `https://wttr.in` or `https://wttr.in/New+York,New+York?0`. For more detail about the options available via the request url, see the [wttr.in documentation](https://github.com/chubin/wttr.in). The response of an http request to the specified url is output directly to the console, so in theory you could use a service other than [wttr.in](wttr.in).\n\n\n\nor:\n\n\n\n- `loc`: The location to retrieve the weather for, e.g. \"New York,New York\".\n\n- `style`: One of either \"oneline\", \"day\", or \"full\".\n\n\n\nIn the case both are specified, the `url` parameter is given priority.\n\n\n\nIf you need a proxy to access the internet, specify it in below item:\n\n\n\n- `proxy`: The http proxy server which used to access internet.\n\n\n", "file_path": "README.md", "rank": 69, "score": 2.6681207245451732 }, { "content": "## Alternatives\n\n\n\n`rust-motd` took a lot of inspiration from `panda-motd`.\n\n\n\n- [panda-motd](https://github.com/taylorthurlow/panda-motd): \"a utility for generating a more useful MOTD\", Ruby\n\n- [motd-on-acid](https://github.com/x70b1/motd-on-acid): \"This MOTD has so many colors!\", Shell\n\n- [fancy-motd](https://github.com/bcyran/fancy-motd): \"Fancy, colorful MOTD written in bash.

I reccomend using at least `info`.\n\n\n\n## Commands: \n\n### !ping: \n\nTougou replies saying \"Pong!\"\n\n\n\n### !pic: \n\n(warning: likely to be NSFW) \n\nThis command fetches a random image from the danbooru site. \n\nUsage: `!pic [tag(s)]`. Tags are optional and space separated. Note: The Danbooru API caps the number of tags that can constrain a query to 2.\n\n\n\n### !tag: \n\nThis command allows you to set tougou to memorise and recall phrases. \n\nExample: \n\n```\n\nyou: !ntag tag_name some tag body\n\ntougou: 新しいタッグ「tag_name」➡「some tag body」を作った。\n\nyou: !tag tag_name\n\ntougou: some tag body\n\n```\n\n\n\n### !jisho:\n\nThis command allows you to check for the definition and/or reading of a japanese word. This command uses the jisho.org api. \n\nExample: \n\n```\n\nyou: !jisho wipe\n\ntougou: 言葉：拭く\n\n 読み方：ふく\n\n 言葉の意味：to wipe; to dry\n\n 続き：https://jisho.org/search/wipe\n\n```\n\n\n\n### !vndb: \n\nWarning: Lkely to be NSFW. \n\nThis command allows you to search the vndb website for visual novels.\n\nExample:\n\n```\n\nyou: !vndb lisp \n\ntougou: https://vndb.org/v7754\n\n 続き：https://vndb.org/v/all?sq=lisp;o=d;s=rating\n\n```\n", "file_path": "README.md", "rank": 65, "score": 6.189483795528158 }, { "content": " match response.status() {\n\n StatusCode::TEMPORARY_REDIRECT => {\n\n let location_header = response\n\n .headers()\n\n .get(reqwest::header::LOCATION)\n\n .ok_or_else(\|\| {\n\n VNDBOrgRepositoryError::new(String::from(\n\n \"VNDB API returned redirect but there was no location header\",\n\n ))\n\n })?\n\n .to_str()?\n\n .to_owned();\n\n result = VNDBResult::Single(format!(\"https://vndb.org{}\", location_header));\n\n }\n\n StatusCode::OK => {\n\n let recomended_link = get_recomended_link(&response.text()?)?;\n\n\n\n result = VNDBResult::MostLikelyAndMore(\n\n format!(\"https://vndb.org{}\", recomended_link),\n\n request_uri,\n", "file_path": "src/data_access/vndb_repository/vndb_org_repository.rs", "rank": 66, "score": 6.111524427724049 }, { "content": "use crate::models::vndb_result::VNDBResult;\n\n\n", "file_path": "src/data_access/vndb_repository/mod.rs", "rank": 67, "score": 5.24719748621664 }, { "content": "pub mod jisho_definition;\n\npub mod pic;\n\npub mod tag;\n\npub mod vndb_result;\n", "file_path": "src/models/mod.rs", "rank": 68, "score": 5.185057929650384 }, { "content": " let japanese_section = first_response_model_data.japanese.first().ok_or_else(\|\| {\n\n JishoOrgRepositoryError::new(String::from(\"japanese section was empty\"))\n\n })?;\n\n\n\n let senses_section = first_response_model_data.senses.first().ok_or_else(\|\| {\n\n JishoOrgRepositoryError::new(String::from(\"senses section was empty\"))\n\n })?;\n\n\n\n Ok(JishoDefinition {\n\n word: match japanese_section.word.clone() {\n\n Some(word) => word,\n\n None => japanese_section.reading.clone(),\n\n },\n\n reading: japanese_section.reading.clone(),\n\n english_definitions: senses_section.english_definitions.clone(),\n\n parts_of_speech: senses_section.parts_of_speech.clone(),\n\n link_for_more: format!(\"https://jisho.org/search/{}\", parameters),\n\n })\n\n }\n\n}\n", "file_path": "src/data_access/jisho_repository/jisho_org_repository.rs", "rank": 69, "score": 4.307117503894792 }, { "content": "pub struct JishoDefinition {\n\n pub word: String,\n\n pub reading: String,\n\n pub english_definitions: Vec<String>,\n\n pub parts_of_speech: Vec<String>,\n\n pub link_for_more: String,\n\n}\n", "file_path": "src/models/jisho_definition.rs", "rank": 70, "score": 3.214740848929359 }, { "content": "pub struct Tag {\n\n pub name: String,\n\n pub body: String,\n\n}\n", "file_path": "src/models/tag.rs", "rank": 71, "score": 3.1735606309062883 }, { "content": "pub mod jisho_repository;\n\npub mod pic_repository;\n\npub mod tag_repository;\n\npub mod vndb_repository;\n", "file_path": "src/data_access/mod.rs", "rank": 72, "score": 3.1178812744655966 }, { "content": "pub struct Pic {\n\n pub uri: String,\n\n}\n", "file_path": "src/models/pic.rs", "rank": 73, "score": 3.0601136822378816 }, { "content": "use crate::data_access::jisho_repository::JishoRepository;\n\nuse crate::models::jisho_definition::JishoDefinition;\n\nuse reqwest;\n\nuse serde_derive::Deserialize;\n\n\n\n#[derive(Deserialize)]\n", "file_path": "src/data_access/jisho_repository/jisho_org_repository.rs", "rank": 74, "score": 2.9138126944260754 }, { "content": " let link_to_vn_element = first_column_children.first()?;\n\n\n\n if let NodeData::Element { ref attrs, .. } = link_to_vn_element.data {\n\n for link_attribute in attrs.borrow().iter() {\n\n if &link_attribute.name.local == \"href\" {\n\n return Some(format!(\"{}\", link_attribute.value));\n\n }\n\n }\n\n };\n\n }\n\n }\n\n }\n\n }\n\n\n\n for child in node.children.borrow().iter() {\n\n if let Some(value) = find_top_table_result(child) {\n\n return Some(value);\n\n };\n\n }\n\n None\n\n}\n\n\n", "file_path": "src/data_access/vndb_repository/vndb_org_repository.rs", "rank": 75, "score": 2.714774793116753 }, { "content": "use crate::models::pic::Pic;\n\n\n", "file_path": "src/data_access/pic_repository/mod.rs", "rank": 76, "score": 2.5204092217157266 }, { "content": "use crate::models::tag::Tag;\n\n\n", "file_path": "src/data_access/tag_repository/mod.rs", "rank": 77, "score": 2.5204092217157266 }, { "content": "use crate::models::jisho_definition::JishoDefinition;\n\n\n", "file_path": "src/data_access/jisho_repository/mod.rs", "rank": 78, "score": 2.406977085109091 } ]

Links are an abstraction used by the runtime to link processors and classifiers together, to manage the flow of packets through the router.\n\n//!

AGLFN comprises the set of glyph names from AGL that map via the AGL Specification rules to the semantically correct UV (*Unicode Value*). For example, \"Asmall\" is omitted because AGL maps this glyph name to the PUA (*Private Use Area*) value U+F761, rather than to the UV that maps from the glyph name \"A.\" Also omitted is \"ffi,\" because AGL maps this to the Alphabetic Presentation Forms value U+FB03, rather than decomposing it into the following sequence of three UVs: U+0066, U+0066, and U+0069. The name \"arrowvertex\" has been omitted because this glyph now has a real UV, and AGL is now incorrect in mapping it to the PUA value U+F8E6. If you do not find an appropriate name for your glyph in this list, then please refer to Section 6 of the AGL Specification.\n\n\n\nThe *ITC Zapf Dingbats Glyph List* is similar to AGL in that it simply provides mappings from glyph names to Unicode scalar values, but only for glyphs in the ITC Zapf Dingbats font.\n\n\n", "file_path": "resources/font/adobe_glyph_list/README.md", "rank": 10, "score": 48985.92950950212 }, { "content": "## Format\n\n\n\nEach record in AGL (*glyphlist.txt*) and the *ITC Zapf Dingbats Glyph List* (*zapfdingbats.txt*) is comprised of two semicolon-delimited fields, described as follows:\n\n\n\n* Glyph name—*upper/lowercase letters and digits*\n\n* Unicode scalar value—*four uppercase hexadecimal digits*\n\n\n\nThe AGL and *ITC Zapf Dingbats Glyph List* records are sorted by glyph name in increasing ASCII order, lines starting with \"#\" are comments, and blank lines should be ignored.\n\n\n\nEach record in AGLFN (*aglfn.txt*) is comprised of three semicolon-delimited fields, described as follows:\n\n\n\n* Standard UV or CUS (*Corporate Use Subarea*) UV—*four uppercase hexadecimal digits*\n\n* Glyph name—*upper/lowercase letters and digits*\n\n* Character names: Unicode character names for standard UVs, and descriptive names for CUS UVs—*uppercase letters, hyphen, and space*\n\n\n\nThe AGLFN records are sorted by glyph name in increasing ASCII order, entries with the same glyph name are sorted in decreasing priority order, the UVs and Unicode character names are provided for convenience, lines starting with \"#\" are comments, and blank lines should be ignored.\n\n\n\n## More Information\n\n\n\nImportant details about glyph naming and interpreting glyph names can be found in the [AGL Specification](https://github.com/adobe-type-tools/agl-specification), which is an open specification.\n\n\n\nThe tools and documentation that comprise [AFDKO (*Adobe Font Development Kit for OpenType*)](http://www.adobe.com/devnet/opentype/afdko.html) are helpful for those who develop OpenType fonts.

Components can be enabled or disabled by including or removing/commenting out the relevant section of configuration. An example configuration file is included in [example_config.toml](example_config.toml).\n\n\n\nA configuration file can either be specified as the first argument to `rust-motd` via the comnmand line or placed in one of two default locations. If a config file is not specified as an argument, `rust-motd` will check `$XDG_CONFIG_HOME/rust-motd/config.toml` and `$HOME/.config/rust-motd/config.toml` in that order.\n\n\n\nThe options for each component are listed below:\n\n### Banner\n\n\n\n- `color`: The color of the banner text. Options are black, red, green, yellow, blue, magenta, cyan, white, and light variants of each.\n\n- `command`: A command executed via `sh` which generates the banner. For example, you could pipe the output of `hostname` to `figlet` to generate a block letter banner.\n\n\n\n### Weather\n\n\n\nThe weather component allows you to either specify a [wttr.in](https://wttr.in) url, or a location and display style which will be used to build the url.\n\n\n\nEither:\n\n\n\n- `url`: a [wttr.in](https://wttr.in) query url for the relevant location. E.g. `https://wttr.in` or `https://wttr.in/New+York,New+York?0`. For more detail about the options available via the request url, see the [wttr.in documentation](https://github.com/chubin/wttr.in). The response of an http request to the specified url is output directly to the console, so in theory you could use a service other than [wttr.in](wttr.in).\n\n\n\nor:\n\n\n\n- `loc`: The location to retrieve the weather for, e.g. \"New York,New York\".\n\n- `style`: One of either \"oneline\", \"day\", or \"full\".\n\n\n\nIn the case both are specified, the `url` parameter is given priority.\n\n\n\nIf you need a proxy to access the internet, specify it in below item:\n\n\n\n- `proxy`: The http proxy server which used to access internet.\n\n\n", "file_path": "README.md", "rank": 69, "score": 2.6681207245451732 }, { "content": "## Alternatives\n\n\n\n`rust-motd` took a lot of inspiration from `panda-motd`.\n\n\n\n- [panda-motd](https://github.com/taylorthurlow/panda-motd): \"a utility for generating a more useful MOTD\", Ruby\n\n- [motd-on-acid](https://github.com/x70b1/motd-on-acid): \"This MOTD has so many colors!\", Shell\n\n- [fancy-motd](https://github.com/bcyran/fancy-motd): \"Fancy, colorful MOTD written in bash.

It can be used in addition to the main [Activeledger Rust SDK](https://crates.io/crates/activeledger) or on its own.\n\nThis crate provides Rust developers an easy way to build up transactions without needing other crates, such as Serde.\n\n\n\nThis crate provides macros as well as builders that help create a transaction with the correct structure.\n\nAdditionally it provides two methods of creating a complete onboarding transaction.

Links are an abstraction used by the runtime to link processors and classifiers together, to manage the flow of packets through the router.\n\n//! Processors and Classifiers, which implement all the non-flow business logic of the router, are loaded into links to create specfic behavior.\n\n//! Links are composed together via the `Link` trait. The `TokioRunnable` portions are handed to Tokio (some Links, such as `QueueLink`, are async\n\n//! and rely on Tokio to pull packets from the upstream.)\n\n//! When the library user uses Graphgen, Links are declared, connected, and placed into a runtime via generated code. The user does this by laying\n\n//! out their desired graph of Processors and Classifiers in a graph file, and Graphgen does all the work from there! Additionally, since all links\n\n//! must implement the LinkBuilder trait, Links are transparently composable at no cost during runtime! The most basic links that implement Poll,\n\n//!
