|
||||
|
||||
You should use the [latest distribution of the Go language for your OS and architecture](https://golang.org/dl/). (If `uname -m` on your Raspberry Pi reports `armv7l`, use the `armv6l` distribution of Go; if it reports v8, you may be able to use the `arm64` distribution.)
|
||||
|
||||
Oragono vendors all its dependencies. The vendored code is tracked via a git submodule: `vendor/` is a submodule pointing to the [oragono-vendor](https://github.com/oragono/oragono-vendor) repository. As long as you're not modifying the vendored dependencies, `make` should take care of everything for you --- but if you are, see the "vendor" section below.
|
||||
|
||||
Because of this, Oragono is self-contained and you should not need to fetch any dependencies with `go get`. Doing so is not recommended, since it may fetch incompatible versions of the dependencies. If you're having trouble building the code, it's very likely because your clone of the repository is in the wrong place: Go is very opinionated about where you should keep your code. Take a look at the [go workspaces documentation](https://golang.org/doc/code.html) if you're having trouble.

|

## Updating `vendor/`
|
||||
|
||||
The `vendor/` directory holds our dependencies. When we import new repos, we need to update this folder to contain these new deps. This is something that I'll mostly be handling.
|
||||
|
||||
To update this folder:
|
||||
|
||||
1. Install https://github.com/golang/dep
|
||||
2. `cd` to Oragono folder
|
||||
3. `dep ensure -update`
|
||||
4. `cd vendor`
|
||||
5. Commit the changes with the message `"Updated packages"`
|
||||
6. `cd ..`
|
||||
4. Commit the result with the message `"vendor: Updated submodules"`
|
||||
|
||||
This will make sure things stay nice and up-to-date for users.
|
||||
|
||||
|
||||
## Fuzzing and Testing
|
||||
|
||||
Fuzzing can be useful. We don't have testing done inside the IRCd itself, but this fuzzer I've written works alright and has helped shake out various bugs: [irc_fuzz.py](https://gist.github.com/DanielOaks/63ae611039cdf591dfa4).

direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the

||||
outstanding shares, or (iii) beneficial ownership of such entity.
|

|
||||
exercising permissions granted by this License.
|
||||

|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||

|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

||||

||||

[](https://godoc.org/github.com/docopt/docopt.go)
|
||||
|
||||
An implementation of [docopt](http://docopt.org/) in the [Go](http://golang.org/) programming language.
|
||||
|
||||
**docopt** helps you create *beautiful* command-line interfaces easily:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/docopt/docopt-go"
|
||||
)
|
||||
|
||||
func main() {
|
||||
usage := `Naval Fate.
|
||||
|
||||
Usage:
|
||||
naval_fate ship new <name>...
|
||||
naval_fate ship <name> move <x> <y> [--speed=<kn>]
|
||||
naval_fate ship shoot <x> <y>
|
||||
naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
|
||||
naval_fate -h | --help
|
||||
naval_fate --version
|
||||
|
||||
Options:
|
||||
-h --help Show this screen.
|
||||
--version Show version.
|
||||
--speed=<kn> Speed in knots [default: 10].
|
||||
--moored Moored (anchored) mine.
|
||||
--drifting Drifting mine.`
|
||||
|
||||
arguments, _ := docopt.ParseDoc(usage)
|
||||
fmt.Println(arguments)
|
||||
}
|
||||
```
|
||||
|
||||
**docopt** parses command-line arguments based on a help message. Don't write parser code: a good help message already has all the necessary information in it.
|
||||
|
||||
## Installation
|
||||
|
||||
⚠ Use the alias "docopt-go". To use docopt in your Go code:
|
||||
|
||||
```go
|
||||
import "github.com/docopt/docopt-go"
|
||||
```
|
||||
|
||||
To install docopt in your `$GOPATH`:
|
||||
|
||||
```console
|
||||
$ go get github.com/docopt/docopt-go
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
Given a conventional command-line help message, docopt processes the arguments. See https://github.com/docopt/docopt#help-message-format for a description of the help message format.
|
||||
|
||||
This package exposes three different APIs, depending on the level of control required. The first, simplest way to parse your docopt usage is to just call:
|
||||
|
||||
```go
|
||||
docopt.ParseDoc(usage)
|
||||
```
|
||||
|
||||
This will use `os.Args[1:]` as the argv slice, and use the default parser options. If you want to provide your own version string and args, then use:
|
||||
|
||||
```go
|
||||
docopt.ParseArgs(usage, argv, "1.2.3")
|
||||
```
|
||||
|
||||
If the last parameter (version) is a non-empty string, it will be printed when `--version` is given in the argv slice. Finally, we can instantiate our own `docopt.Parser` which gives us control over how things like help messages are printed and whether to exit after displaying usage messages, etc.
|
||||
|
||||
```go
|
||||
parser := &docopt.Parser{
|
||||
HelpHandler: docopt.PrintHelpOnly,
|
||||
OptionsFirst: true,
|
||||
}
|
||||
opts, err := parser.ParseArgs(usage, argv, "")
|
||||
```
|
||||
|
||||
In particular, setting your own custom `HelpHandler` function makes unit testing your own docs with example command line invocations much more enjoyable.
|
||||
|
||||
All three of these return a map of option names to the values parsed from argv, and an error or nil. You can get the values using the helpers, or just treat it as a regular map:
|
||||
|
||||
```go
|
||||
flag, _ := opts.Bool("--flag")
|
||||
secs, _ := opts.Int("<seconds>")
|
||||
```
|
||||
|
||||
Additionally, you can `Bind` these to a struct, assigning option values to the
|
||||
exported fields of that struct, all at once.
|
||||
|
||||
```go
|
||||
var config struct {
|
||||
Command string `docopt:"<cmd>"`
|
||||
Tries int `docopt:"-n"`
|
||||
Force bool // Gets the value of --force
|
||||
}
|
||||
opts.Bind(&config)
|
||||
```
|
||||
|
||||
More documentation is available at [godoc.org](https://godoc.org/github.com/docopt/docopt-go).
|
||||
|
||||
## Unit Testing
|
||||
|
||||
Unit testing your own usage docs is recommended, so you can be sure that for a given command line invocation, the expected options are set. An example of how to do this is [in the examples folder](examples/unit_test/unit_test.go).
|
||||
|
||||
## Tests
|
||||
|
||||
All tests from the Python version are implemented and passing at [Travis CI](https://travis-ci.org/docopt/docopt-go). New language-agnostic tests have been added to [test_golang.docopt](test_golang.docopt).
|
||||
|
||||
To run tests for docopt-go, use `go test`.

ε-NFA: Epsilon-Nondeterministic finite automaton
|
||||
==============
|
||||
|

What is Epsilon-Nondeterministic finite automaton
|
||||
=============
|
||||
|
||||
`ε-NFA`: Epsilon-Nondeterministic finite automaton (so call:Nondeterministic finite automaton with ε-moves)
|
||||
|
||||
In the automata theory, a nondeterministic finite automaton with ε-moves (NFA-ε)(also known as NFA-λ) is an extension of nondeterministic finite automaton(NFA), which allows a transformation to a new state without consuming any input symbols. The transitions without consuming an input symbol are called ε-transitions or λ-transitions. In the state diagrams, they are usually labeled with the Greek letter ε or λ.

||||

||||

|
||||
|
||||
Install
|
||||

|
||||
|
||||
|
||||
|
||||
Usage
|
||||
---------------
|
||||
|
||||
Following is sample code to implement a epsilon-NFA automata diagram as follow:
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
```go
|
||||
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/kkdai/enfa"
|
||||
"fmt"
|
||||
)
|
||||
|
||||
func main() {
|
||||
|
||||
nfa := NewENFA(0, false)
|
||||
nfa.AddState(1, false)
|
||||
nfa.AddState(2, false)
|
||||
nfa.AddState(3, true)
|
||||
nfa.AddState(4, false)
|
||||
nfa.AddState(5, false)
|
||||
|
||||
nfa.AddTransition(0, "1", 1)
|
||||
nfa.AddTransition(0, "0", 4)
|
||||
|
||||
nfa.AddTransition(1, "1", 2)
|
||||
nfa.AddTransition(1, "", 3) //epsilon
|
||||
nfa.AddTransition(2, "1", 3)
|
||||
nfa.AddTransition(4, "0", 5)
|
||||
nfa.AddTransition(4, "", 1, 2) //E -> epsilon B C
|
||||
nfa.AddTransition(5, "0", 3)
|
||||
|
||||
nfa.PrintTransitionTable()
|
||||
|
||||
if !nfa.VerifyInputs([]string{"1"}) {
|
||||
fmt.Printf("Verify inputs is failed")
|
||||
}
|
||||
|
||||
nfa.Reset()
|
||||
|
||||
if !nfa.VerifyInputs([]string{"1", "1", "1"}) {
|
||||
fmt.Printf("Verify inputs is failed")
|
||||
}
|
||||
|
||||
nfa.Reset()
|
||||
|
||||
if !nfa.VerifyInputs([]string{"0", "1"}) {
|
||||
fmt.Printf"Verify inputs is failed")
|
||||
}
|
||||
|

/*
|
||||
Package ircfmt handles IRC formatting codes, escaping and unescaping.
|
||||
|
||||
This allows for a simpler representation of strings that contain colour codes,
|
||||
bold codes, and such, without having to write and handle raw bytes when
|
||||
assembling outgoing messages.
|
||||
|
||||
This lets you turn raw IRC messages into our escaped versions, and turn escaped
|
||||
versions back into raw messages suitable for sending on IRC connections. This
|
||||
is designed to be used on things like PRIVMSG / NOTICE commands, MOTD blocks,
|
||||
and such.
|
||||
|
||||
The escape character we use in this library is the dollar sign ("$"), along
|
||||
with the given escape characters:
|
||||
|
||||
--------------------------------
|
||||
Name | Escape | Raw
|
||||
--------------------------------
|
||||
Dollarsign | $$ | $
|
||||
Bold | $b | 0x02
|
||||
Colour | $c | 0x03
|
||||
Monospace | $m | 0x11
|
||||
Reverse Colour | $v | 0x16
|
||||
Italic | $i | 0x1d
|
||||
Strikethrough | $s | 0x1e
|
||||
Underscore | $u | 0x1f
|
||||
Reset | $r | 0x0f
|
||||
--------------------------------
|
||||
|
||||
Colours are escaped in a slightly different way, using the actual names of them
|
||||
rather than just the raw numbers.
|
||||
|
||||
In our escaped format, the colours for the fore and background are contained in
|
||||
square brackets after the colour ("$c") escape. For example:
|
||||
|
||||
Red foreground:
|
||||
Escaped: This is a $c[red]cool message!
|
||||
Raw: This is a 0x034cool message!
|
||||
|
||||
Blue foreground, green background:
|
||||
Escaped: This is a $c[blue,green]rad message!
|
||||
Raw: This is a 0x032,3rad message!
|
||||
|
||||
When assembling a raw message, we make sure to use the full colour code
|
||||
("02" vs just "2") when it could become confused due to numbers just after the
|
||||
colour escape code. For instance, lines like this will be unescaped correctly:
|
||||
|
||||
No number after colour escape:
|
||||
Escaped: This is a $c[red]cool message!
|
||||
Raw: This is a 0x034cool message!
|
||||
|
||||
Number after colour escape:
|
||||
Escaped: This is $c[blue]20% cooler!
|
||||
Raw: This is 0x030220% cooler
|
||||
|
||||
Here are the colour names and codes we recognise:
|
||||
|
||||
--------------------
|
||||
Code | Name
|
||||
--------------------
|
||||
00 | white
|
||||
01 | black
|
||||
02 | blue
|
||||
03 | green
|
||||
04 | red
|
||||
05 | brown
|
||||
06 | magenta
|
||||
07 | orange
|
||||
08 | yellow
|
||||
09 | light green
|
||||
10 | cyan
|
||||
11 | light cyan
|
||||
12 | light blue
|
||||
13 | pink
|
||||
14 | grey
|
||||
15 | light grey
|
||||
99 | default
|
||||
--------------------
|
||||
|
||||
These other colours aren't given names:

Colorable writer for windows.
|
||||
|
||||
For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
|
||||
This package is possible to handle escape sequence for ansi color on windows.
|
||||
|
||||
## Too Bad!
|
||||
|
||||
|
||||
|
||||
|
||||
## So Good!
|
||||
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
|
||||
logrus.SetOutput(colorable.NewColorableStdout())
|
||||
|
||||
logrus.Info("succeeded")
|
||||
logrus.Warn("not correct")
|
||||
logrus.Error("something error")
|
||||
logrus.Fatal("panic")
|
||||
```
|
||||
|
||||
You can compile above code on non-windows OSs.
|
||||
|
||||
## Installation
|
||||
|
||||
```
|
||||
$ go get github.com/mattn/go-colorable
|
||||

# ansi
|
||||
|
||||
Package ansi is a small, fast library to create ANSI colored strings and codes.
|
||||
|
||||
## Install
|
||||
|
||||
Get it
|
||||
|
||||
```sh
|
||||
go get -u github.com/mgutz/ansi
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
```go
|
||||
import "github.com/mgutz/ansi"
|
||||
|
||||
// colorize a string, SLOW
|
||||
msg := ansi.Color("foo", "red+b:white")
|
||||
|
||||
// create a FAST closure function to avoid computation of ANSI code
|
||||
phosphorize := ansi.ColorFunc("green+h:black")
|
||||
msg = phosphorize("Bring back the 80s!")
|
||||
msg2 := phospohorize("Look, I'm a CRT!")
|
||||
|
||||
// cache escape codes and build strings manually
|
||||
lime := ansi.ColorCode("green+h:black")
|
||||
reset := ansi.ColorCode("reset")
|
||||
|
||||
fmt.Println(lime, "Bring back the 80s!", reset)
|
||||
```
|
||||
|
||||
Other examples
|
||||
|
||||
```go
|
||||
Color(s, "red") // red
|
||||
Color(s, "red+b") // red bold
|
||||
Color(s, "red+B") // red blinking
|
||||
Color(s, "red+u") // red underline
|
||||
Color(s, "red+bh") // red bold bright
|
||||
Color(s, "red:white") // red on white
|
||||
Color(s, "red+b:white+h") // red bold on white bright
|
||||
Color(s, "red+B:white+h") // red blink on white bright
|
||||
Color(s, "off") // turn off ansi codes
|
||||
```
|
||||
|
||||
To view color combinations, from project directory in terminal.
|
||||
|
||||
```sh
|
||||
go test
|
||||
```
|
||||
|
||||

Package ansi is a small, fast library to create ANSI colored strings and codes.
|
||||
|
||||
Installation
|
||||
|
||||
# this installs the color viewer and the package
|
||||
go get -u github.com/mgutz/ansi/cmd/ansi-mgutz
|
||||
|
||||
Example
|
||||
|
||||
// colorize a string, SLOW
|
||||
msg := ansi.Color("foo", "red+b:white")
|
||||
|
||||
// create a closure to avoid recalculating ANSI code compilation
|
||||
phosphorize := ansi.ColorFunc("green+h:black")
|
||||
msg = phosphorize("Bring back the 80s!")
|
||||
msg2 := phospohorize("Look, I'm a CRT!")
|
||||
|
||||
// cache escape codes and build strings manually
|
||||
lime := ansi.ColorCode("green+h:black")
|
||||
reset := ansi.ColorCode("reset")
|
||||
|
||||
fmt.Println(lime, "Bring back the 80s!", reset)
|
||||
|
||||
Other examples
|
||||
|
||||
Color(s, "red") // red
|
||||
Color(s, "red+b") // red bold
|
||||
Color(s, "red+B") // red blinking
|
||||
Color(s, "red+u") // red underline
|
||||
Color(s, "red+bh") // red bold bright
|
||||
Color(s, "red:white") // red on white
|
||||
Color(s, "red+b:white+h") // red bold on white bright
|
||||
Color(s, "red+B:white+h") // red blink on white bright

# Unicode confusables
|
||||
|
||||
This Go library implements the `Skeleton` algorithm from Unicode TR39
|
||||
|
||||
See http://www.unicode.org/reports/tr39/
|
||||
|
||||
### Examples
|
||||
```
|
||||
import "github.com/mtibben/confusables"
|
||||
|
||||
confusables.Skeleton("𝔭𝒶ỿ𝕡𝕒ℓ") # "paypal"
|
||||
confusables.Confusable("𝔭𝒶ỿ𝕡𝕒ℓ", "paypal") # true
|
||||
```
|
||||
|
||||
*Note on the use of `Skeleton`, from TR39:*
|
||||
|
||||
> A skeleton is intended only for internal use for testing confusability of strings; the resulting text is not suitable for display to users, because it will appear to be a hodgepodge of different scripts. In particular, the result of mapping an identifier will not necessary be an identifier. Thus the confusability mappings can be used to test whether two identifiers are confusable (if their skeletons are the same), but should definitely not be used as a "normalization" of identifiers.
