-This is not an official Goggle package, and is not supported by Google.
+This package defines symbolic names for some character codes (aka. code points).
-## Using
+They can used when working directly with characters as integers,
+to make the code more readable: `if (firstChar == $A) ...`.
+
+This is not an official Google package, and is not supported by Google.
+
+## Usage
Import either one of the libraries:
-
- import "package:charcode/ascii.dart"
- import "package:charcode/html_entity.dart"
-
+```dart
+import "package:charcode/ascii.dart";
+import "package:charcode/html_entity.dart";
+```
or import both libraries using the `charcode.dart` library:
+```dart
+import "package:charcode/charcode.dart";
+```
- import "package:charcode/charcode.dart"
-
-# Naming
+## Naming
The character names are preceded by a `$` to avoid conflicting with other
-variables due to the short and common names (for example "$i").

-The characters that are valid in a Dart identifier directly follow the `$`.
+Characters that are valid in a Dart identifier directly follow the `$`.
Examples: `$_`, `$a`, `$B` and `$3`. Other characters are given symbolic names.
-The names of letters are lower-case for lower-case letters, and mixed- or
-upper-case for upper-case letters. The names of symbols are all lower-case,
-and omit suffixes like "sign", "symbol" and "mark". E
-xamples: `$plus`, `$exclamation`
+The names of letters are lower-case for lower-case letters (`$sigma` for `σ`),
+and mixed- or upper-case for upper-case letters (`$Sigma` for `Σ`).
+The names of symbols and punctuation are all lower-case,
+and omit suffixes like "sign", "symbol" and "mark".
+Examples: `$plus`, `$exclamation`, `$tilde`.
The `ascii.dart` library defines a symbolic name for each ASCII character.
-For some chraceters, it has more than one name. For example the common `$tab`
-and the official `$ht` for the horisontal tab.
+Some characters have more than one name. For example the common name `$tab`

The `html_entity.dart` library defines a constant for each HTML 4.01 character

+entity using their standard entity abbreviation, including case.
Examples: `$nbsp` for `&nbps;`, `$aring` for the lower-case `å`
and `$Aring` for the upper-case `Å`.

+The HTML entities include all characters in the Latin-1 code page, greek
letters and some mathematical symbols.
-The `charcode.dart` library just exports both `ascii.dart` and

+The `charcode.dart` library exports both `ascii.dart` and

+
+import 'package:charcode/ascii.dart';
+
+import "src/uflags.dart";
+
+/// Generates Dart constant declarations for character codes.
+///
+/// Usage:
+/// ```text
+/// charcode (character-range | rename | flags)*
+/// ```
+///
+/// ## Character ranges
+///
+/// A `character-range` is either
+/// * a single charater,
+/// * an escaped character `\n`, `\r`, `\t`, `\xHH`, `\uHHHH` or `\DD*`,
+/// where `H` is a hexadecimal digit and `D` is a decimal digit.
+/// * two characters separated by `-` or the `\d`, `\w` or `\s` escapes, or
+/// * a sequence of character ranges.
+/// Examples include `a`, `a-z`, or `abe-gz`.
+/// Accepts `\n`, `\r`, `\t`, `\`, `\-`, `\xHH` and `\uHHHHHH` escapes.
+///
+/// A (re)name declaration is a single or escaped character, a `=` and an
+/// identifier name, optionally followed by a `:` and a description
+/// Example: `x=cross:"A cross product."`.
+/// The naming names or renames the character and adds or changes
+/// the associated description.
+/// It will not add the character to the output.
+/// Following occurrences of the character will use the new name.
+/// Example: `y y=why x-z` will generate `$y` for the character
+/// code of "y", then `$x`, `$why` and `$z` as well.
+///
+/// ## Flags
+///
+/// `-o` followed by a file name makes output be written to that file
+/// instead of to stdout.
+///
+/// `-f` followed by a file name will read declarations from that file
+/// as well as from the command line. Each line in the file is handled
+/// like a command line argument (not including flags.)
+/// Intended for importing a set of name declarations.
+/// The line is not split on spaces, so it allows comments with spaces
+/// like:
+/// ```text
+/// x=cross:The cross character.
+/// ```
+///
+/// `-p` followed by zero more characters makes those characters be
+/// used as prefix for later generated names. The default is the `$`
+/// character. If setting an empty prefix, names starting with digits
+/// will still use the previously configured prefix character since
+/// identifiers cannot start with a digit.
+///
+/// `-h` includes declarations for HTML entity names.
+///
+/// `--` disables flags in the following command line arguments.

+Usage:
+ charcode [-h] [-oFILE] (<character-range> | <rename> | -pPREFIX | -fFILE)*
+
+ A <character-range> is either
+ - A literal character,
+ - An escaped character `\n`, `\r`, `\t`, `\xhh`, `\uhhhh` or `\dd*`,
+ where `h` is a hexadecimal digit and `d` is a decimal digit.
+ - Two characters separated by `-`,
+ - The `\d`, `\w` or `\s` escapes, or
+ - A sequence of character ranges.
+ Examples: `a`, `a-z`, `\da-fA-F`, `\x00-\uFFFF`.
+
+ A <rename> declaration is a single or escaped character, a `=` and an
+ identifier name, optionally followed by a `:` and a description
+ Example: x=cross:\"a cross product.\"
+ The declaration names or renames the character and adds or changes
+ the associated description.
+ It will not add the character to the output.
+ Following occurrences of the character will use the new name.
+ Example: `charcode y y=why x-z` will generate `$y` for the character
+ code of "y", then `$x`, `$why` and `$z` as well.

+/// Flags can have parameters.

+/// Single-character flags can have an parameter:

+/// * with a `=` between them, `-o=filename`,
