+TextRank on Go +

+ +

+ + GoDoc + + + License: MIT + + + Build Status + + + Go Report Card + + + Coverage Status + + + Release + + +

+ +

+This source code is an implementation of textrank algorithm, under MIT licence. +
The minimum requred Go version is 1.8. +

+
+ +## MOTIVATION + +If there was a program what could rank book size text's words, phrases and sentences continuously on multiple threads and it would be opened to modifing by objects, written in a simple, secure, static language and if it would be very well documented... Now, here it is. + +## FEATURES + +* Find the most important phrases. +* Find the most important words. +* Find the most important N sentences. + * Importance by phrase weights. + * Importance by word occurrence. +* Find the first N sentences, start from Xth sentence. +* Find sentences by phrase chains ordered by position in text. +* Access to the whole ranked data. +* Support more languages. +* Algorithm for weighting can be modified by interface implementation. +* Parser can be modified by interface implementation. +* Multi thread support. + +## INSTALL + +You can install TextRank by Go's get: + +```go get github.com/DavidBelicza/TextRank``` + +TextRank uses the default Go *mod* as vendoring tool, so you can install the dependencies with this command: + +```go mod vendor``` + +## DOCKER + +Using Docker to TextRank isn't necessary, it's just an option. + +Build image from the repository's root directory: + +```docker build -t go_text_rank_image .``` + +Create container from the image: + +```docker run -dit --name textrank go_text_rank_image:latest``` + +Run the **go test -v .** code inside the container: + +```docker exec -i -t textrank go test -v .``` + +Stop, start or remove the container: + +* ```docker stop textrank``` +* ```docker start textrank``` +* ```docker rm textrank``` + +## HOW DOES IT WORK + +Too see how does it work, the easiest way is to use the sample text. Sample text can be found in the [textrank_test.go file at this line](https://github.com/DavidBelicza/TextRank/blob/master/textrank_test.go#L12). It's a short size text about Gnome Shell. + +* TextRank reads the text, + * parse it, + * remove the unnecessary stop words, + * tokenize it +* and counting the occurrence of the words and phrases +* and then it starts weighting + * by the occurrence of words and phrases and their relations. +* After weights are done, TextRank normalize weights to between 1 and 0. +* Then the different finder methods capable to find the most important words, phrases or sentences. + +The most important phrases from the sample text are: + +Phrase | Occurrence | Weight +--- | --- | --- +gnome - shell | 5 | 1 +extension - gnome | 3 | 0.50859946 +icons - tray | 3 | 0.49631447 +gnome - caffeine | 2 | 0.27027023 + +The **gnome** is the most often used word in this text and **shell** is also used multiple times. Two of them are used together as a phrase 5 times. This is the highest occurrence in this text, so this is the most important phrase. + +The following two important phrases have same occurrence 3, however they are not equal. This is because the **extension gnome** phrase contains the word **gnome**, the most popular word in the text, and it increases the phrase's weight. It increases the weight of any word what is related to it, but not too much to overcome other important phrases what don't contain the **gnome** word. + +The exact algorithm can be found in the [algorithm.go file at this line](https://github.com/DavidBelicza/TextRank/blob/master/rank/algorithm.go#L65). + +## TEXTRANK OR AUTOMATIC SUMMARIZATION +> Automatic summarization is the process of reducing a text document with a computer program in order to create a summary that retains the most important points of the original document. Technologies that can make a coherent summary take into account variables such as length, writing style and syntax. Automatic data summarization is part of machine learning and data mining. The main idea of summarization is to find a representative subset of the data, which contains the information of the entire set. Summarization technologies are used in a large number of sectors in industry today. - Wikipedia + +## EXAMPLES + +### Find the most important phrases + +This is the most basic and simplest usage of textrank. + +```go +package main + +import ( + "fmt" + + "github.com/DavidBelicza/TextRank/v2" +) + +func main() { + rawText := "Your long raw text, it could be a book. Lorem ipsum..." + // TextRank object + tr := textrank.NewTextRank() + // Default Rule for parsing. + rule := textrank.NewDefaultRule() + // Default Language for filtering stop words. + language := textrank.NewDefaultLanguage() + // Default algorithm for ranking text. + algorithmDef := textrank.NewDefaultAlgorithm() + + // Add text. + tr.Populate(rawText, language, rule) + // Run the ranking. + tr.Ranking(algorithmDef) + + // Get all phrases by weight. + rankedPhrases := textrank.FindPhrases(tr) + + // Most important phrase. + fmt.Println(rankedPhrases[0]) + // Second important phrase. + fmt.Println(rankedPhrases[1]) +} +``` + +### All possible pre-defined finder queries + +After ranking, the graph contains a lot of valuable data. There are functions in textrank package what contains logic to retrieve those data from the graph. + +```go +package main + +import ( + "fmt" + + "github.com/DavidBelicza/TextRank/v2" +) + +func main() { + rawText := "Your long raw text, it could be a book. Lorem ipsum..." + // TextRank object + tr := textrank.NewTextRank() + // Default Rule for parsing. + rule := textrank.NewDefaultRule() + // Default Language for filtering stop words. + language := textrank.NewDefaultLanguage() + // Default algorithm for ranking text. + algorithmDef := textrank.NewDefaultAlgorithm() + + // Add text. + tr.Populate(rawText, language, rule) + // Run the ranking. + tr.Ranking(algorithmDef) + + // Get all phrases order by weight. + rankedPhrases := textrank.FindPhrases(tr) + // Most important phrase. + fmt.Println(rankedPhrases[0]) + + // Get all words order by weight. + words := textrank.FindSingleWords(tr) + // Most important word. + fmt.Println(words[0]) + + // Get the most important 10 sentences. Importance by phrase weights. + sentences := textrank.FindSentencesByRelationWeight(tr, 10) + // Found sentences + fmt.Println(sentences) + + // Get the most important 10 sentences. Importance by word occurrence. + sentences = textrank.FindSentencesByWordQtyWeight(tr, 10) + // Found sentences + fmt.Println(sentences) + + // Get the first 10 sentences, start from 5th sentence. + sentences = textrank.FindSentencesFrom(tr, 5, 10) + // Found sentences + fmt.Println(sentences) + + // Get sentences by phrase/word chains order by position in text. + sentencesPh := textrank.FindSentencesByPhraseChain(tr, []string{"gnome", "shell", "extension"}) + // Found sentence. + fmt.Println(sentencesPh[0]) +} +``` + +### Access to everything + +After ranking, the graph contains a lot of valuable data. The GetRank function allows access to the graph and every data can be retrieved from this structure. + +```go +package main + +import ( + "fmt" + + "github.com/DavidBelicza/TextRank/v2" +) + +func main() { + rawText := "Your long raw text, it could be a book. Lorem ipsum..." + // TextRank object + tr := textrank.NewTextRank() + // Default Rule for parsing. + rule := textrank.NewDefaultRule() + // Default Language for filtering stop words. + language := textrank.NewDefaultLanguage() + // Default algorithm for ranking text. + algorithmDef := textrank.NewDefaultAlgorithm() + + // Add text. + tr.Populate(rawText, language, rule) + // Run the ranking. + tr.Ranking(algorithmDef) + + // Get the rank graph. + rankData := tr.GetRankData() + + // Get word ID by token/word. + wordId := rankData.WordValID["gnome"] + + // Word's weight. + fmt.Println(rankData.Words[wordId].Weight) + // Word's quantity/occurrence. + fmt.Println(rankData.Words[wordId].Qty) + // All sentences what contain the this word. + fmt.Println(rankData.Words[wordId].SentenceIDs) + // All other words what are related to this word on left side. + fmt.Println(rankData.Words[wordId].ConnectionLeft) + // All other words what are related to this word on right side. + fmt.Println(rankData.Words[wordId].ConnectionRight) + // The node of this word, it contains the related words and the relation weight. + fmt.Println(rankData.Relation.Node[wordId]) +} +``` + +### Adding text continuously + +It is possibe to add more text after another texts already have been added. The Ranking function can merge these multiple texts and it can recalculate the weights and all related data. + +```go +package main + +import ( + "fmt" + + "github.com/DavidBelicza/TextRank/v2" +) + +func main() { + rawText := "Your long raw text, it could be a book.

To use other languages a stop word list is required what you can find here: https://github.com/stopwords-iso + +```go +package main + +import ( + "fmt" + + "github.com/DavidBelicza/TextRank/v2" +) + +func main() { + rawText := "Your long raw text, it could be a book.

There are also helper functions +for using the registry in each package, such as looking up lexers by name or +matching filenames, etc. + +In all cases, if a lexer, formatter or style can not be determined, `nil` will +be returned. In this situation you may want to default to the `Fallback` +value in each respective package, which provides sane defaults. + + +### Quick start + +A convenience function exists that can be used to simply format some source +text, without any effort: + +```go +err := quick.Highlight(os.Stdout, someSourceCode, "go", "html", "monokai") +``` + + +### Identifying the language + +To highlight code, you'll first have to identify what language the code is +written in. There are three primary ways to do that: + +1. Detect the language from its filename. + + ```go + lexer := lexers.Match("foo.go") + ``` + +3. Explicitly specify the language by its Chroma syntax ID (a full list is available from `lexers.Names()`). + + ```go + lexer := lexers.Get("go") + ``` + +3. Detect the language from its content. + + ```go + lexer := lexers.Analyse("package main\n\nfunc main()\n{\n}\n") + ``` + +In all cases, `nil` will be returned if the language can not be identified. + +```go +if lexer == nil { + lexer = lexers.Fallback +} +``` + +At this point, it should be noted that some lexers can be extremely chatty. To +mitigate this, you can use the coalescing lexer to coalesce runs of identical +token types into a single token: + +```go +lexer = chroma.Coalesce(lexer) +``` + + +### Formatting the output + +Once a language is identified you will need to pick a formatter and a style (theme). + +```go +style := styles.Get("swapoff") +if style == nil { + style = styles.Fallback +} +formatter := formatters.Get("html") +if formatter == nil { + formatter = formatters.Fallback +} +``` + +Then obtain an iterator over the tokens: + +```go +contents, err := ioutil.ReadAll(r) +iterator, err := lexer.Tokenise(nil, string(contents)) +``` + +And finally, format the tokens from the iterator: + +```go +err := formatter.Format(w, style, iterator) +``` + + +### The HTML formatter + +By default the `html` registered formatter generates standalone HTML with +embedded CSS. More flexibility is available through the `formatters/html` package. + +Firstly, the output generated by the formatter can be customised with the +following constructor options: + +- `Standalone()` - generate standalone HTML with embedded CSS. +- `WithClasses()` - use classes rather than inlined style attributes. +- `ClassPrefix(prefix)` - prefix each generated CSS class. +- `TabWidth(width)` - Set the rendered tab width, in characters. +- `WithLineNumbers()` - Render line numbers (style with `LineNumbers`). +- `LinkableLineNumbers()` - Make the line numbers linkable and be a link to themselves. +- `HighlightLines(ranges)` - Highlight lines in these ranges (style with `LineHighlight`). +- `LineNumbersInTable()` - Use a table for formatting line numbers and code, rather than spans. + +If `WithClasses()` is used, the corresponding CSS can be obtained from the formatter with: + +```go +formatter := html.New(html.WithClasses(true)) +err := formatter.WriteCSS(w, style) +``` + + +## More detail + + +### Lexers + +See the [Pygments documentation](http://pygments.org/docs/lexerdevelopment/) +for details on implementing lexers. Most concepts apply directly to Chroma, +but see existing lexer implementations for real examples. + +In many cases lexers can be automatically converted directly from Pygments by +using the included Python 3 script `pygments2chroma.py`. I use something like +the following: + +```sh +python3 _tools/pygments2chroma.py \ + pygments.lexers.jvm.KotlinLexer \ + > lexers/k/kotlin.go \ + && gofmt -s -w lexers/k/kotlin.go +``` + +See notes in [pygments-lexers.txt](https://github.com/alecthomas/chroma/blob/master/pygments-lexers.txt) +for a list of lexers, and notes on some of the issues importing them. + + +### Formatters + +Chroma supports HTML output, as well as terminal output in 8 colour, 256 colour, and true-colour. + +A `noop` formatter is included that outputs the token text only, and a `tokens` +formatter outputs raw tokens. The latter is useful for debugging lexers. + + +### Styles + +Chroma styles use the [same syntax](http://pygments.org/docs/styles/) as Pygments. + +All Pygments styles have been converted to Chroma using the `_tools/style.py` script. + +When you work with one of [Chroma's styles](https://github.com/alecthomas/chroma/tree/master/styles), know that the `chroma.Background` token type provides the default style for tokens. It does so by defining a foreground color and background color. + +For example, this gives each token name not defined in the style a default color of `#f8f8f8` and uses `#000000` for the highlighted code block's background: + +~~~go +chroma.Background: "#f8f8f2 bg:#000000", +~~~ + +Also, token types in a style file are hierarchical. For instance, when `CommentSpecial` is not defined, Chroma uses the token style from `Comment`. So when several comment tokens use the same color, you'll only need to define `Comment` and override the one that has a different color. + +For a quick overview of the available styles and how they look, check out the [Chroma Style Gallery](https://xyproto.github.io/splash/docs/). + + +## Command-line interface + +A command-line interface to Chroma is included. + +Binaries are available to install from [the releases page](https://github.com/alecthomas/chroma/releases). + +The CLI can be used as a preprocessor to colorise output of `less(1)`, +see documentation for the `LESSOPEN` environment variable. + +The `--fail` flag can be used to suppress output and return with exit status +1 to facilitate falling back to some other preprocessor in case chroma +does not resolve a specific lexer to use for the given file. For example: + +```shell +export LESSOPEN='| p() { chroma --fail "$1" || cat "$1"; }; p "%s"' +``` + +Replace `cat` with your favourite fallback preprocessor. + +When invoked as `.lessfilter`, the `--fail` flag is automatically turned +on under the hood for easy integration with [lesspipe shipping with +Debian and derivatives](https://manpages.debian.org/lesspipe#USER_DEFINED_FILTERS); +for that setup the `chroma` executable can be just symlinked to `~/.lessfilter`. + + +## What's missing compared to Pygments? + +- Quite a few lexers, for various reasons (pull-requests welcome): + - Pygments lexers for complex languages often include custom code to + handle certain aspects, such as Raku's ability to nest code inside + regular expressions. These require time and effort to convert. + - I mostly only converted languages I had heard of, to reduce the porting cost. +- Some more esoteric features of Pygments are omitted for simplicity. +- Though the Chroma API supports content detection, very few languages support them. + I have plans to implement a statistical analyser at some point, but not enough time. diff --git a/vendor/github.com/alecthomas/chroma/v2/coalesce.go b/vendor/github.com/alecthomas/chroma/v2/coalesce.go new file mode 100644 index 0000000..f504895 --- /dev/null +++ b/vendor/github.com/alecthomas/chroma/v2/coalesce.go @@ -0,0 +1,35 @@ +package chroma + +// Coalesce is a Lexer interceptor that collapses runs of common types into a single token. +func Coalesce(lexer Lexer) Lexer { return &coalescer{lexer} } + +type coalescer struct{ Lexer } + +func (d *coalescer) Tokenise(options *TokeniseOptions, text string) (Iterator, error) { + var prev Token + it, err := d.Lexer.Tokenise(options, text) + if err != nil { + return nil, err + } + return func() Token { + for token := it(); token != (EOF); token = it() { + if len(token.Value) == 0 { + continue + } + if prev == EOF { + prev = token + } else { + if prev.Type == token.Type && len(prev.Value) < 8192 { + prev.Value += token.Value + } else { + out := prev + prev = token + return out + } + } + } + out := prev + prev = EOF + return out + }, nil +} diff --git a/vendor/github.com/alecthomas/chroma/v2/colour.go b/vendor/github.com/alecthomas/chroma/v2/colour.go new file mode 100644 index 0000000..15d794c --- /dev/null +++ b/vendor/github.com/alecthomas/chroma/v2/colour.go @@ -0,0 +1,164 @@ +package chroma + +import ( + "fmt" + "math" + "strconv" + "strings" +) + +// ANSI2RGB maps ANSI colour names, as supported by Chroma, to hex RGB values. +var ANSI2RGB = map[string]string{ + "#ansiblack": "000000", + "#ansidarkred": "7f0000", + "#ansidarkgreen": "007f00", + "#ansibrown": "7f7fe0", + "#ansidarkblue": "00007f", + "#ansipurple": "7f007f", + "#ansiteal": "007f7f", + "#ansilightgray": "e5e5e5", + // Normal + "#ansidarkgray": "555555", + "#ansired": "ff0000", + "#ansigreen": "00ff00", + "#ansiyellow": "ffff00", + "#ansiblue": "0000ff", + "#ansifuchsia": "ff00ff", + "#ansiturquoise": "00ffff", + "#ansiwhite": "ffffff", + + // Aliases without the "ansi" prefix, because...why?

Struct-based argument parsing for Go

+

+ Sourcegraph + Documentation + Build Status + Coverage Status + Go Report Card +

+
+ +Declare command line arguments for your program by defining a struct. + +```go +var args struct { + Foo string + Bar bool +} +arg.MustParse(&args) +fmt.Println(args.Foo, args.Bar) +``` + +```shell +$ ./example --foo=hello --bar +hello true +``` + +### Installation + +```shell +go get github.com/alexflint/go-arg +``` + +### Required arguments + +```go +var args struct { + ID int `arg:"required"` + Timeout time.Duration +} +arg.MustParse(&args) +``` + +```shell +$ ./example +Usage: example --id ID [--timeout TIMEOUT] +error: --id is required +``` + +### Positional arguments + +```go +var args struct { + Input string `arg:"positional"` + Output []string `arg:"positional"` +} +arg.MustParse(&args) +fmt.Println("Input:", args.Input) +fmt.Println("Output:", args.Output) +``` + +``` +$ ./example src.txt x.out y.out z.out +Input: src.txt +Output: [x.out y.out z.out] +``` + +### Environment variables + +```go +var args struct { + Workers int `arg:"env"` +} +arg.MustParse(&args) +fmt.Println("Workers:", args.Workers) +``` + +``` +$ WORKERS=4 ./example +Workers: 4 +``` + +``` +$ WORKERS=4 ./example --workers=6 +Workers: 6 +``` + +You can also override the name of the environment variable: + +```go +var args struct { + Workers int `arg:"env:NUM_WORKERS"` +} +arg.MustParse(&args) +fmt.Println("Workers:", args.Workers) +``` + +``` +$ NUM_WORKERS=4 ./example +Workers: 4 +``` + +You can provide multiple values using the CSV (RFC 4180) format: + +```go +var args struct { + Workers []int `arg:"env"` +} +arg.MustParse(&args) +fmt.Println("Workers:", args.Workers) +``` + +``` +$ WORKERS='1,99' ./example +Workers: [1 99] +``` + +### Usage strings +```go +var args struct { + Input string `arg:"positional"` + Output []string `arg:"positional"` + Verbose bool `arg:"-v,--verbose" help:"verbosity level"` + Dataset string `help:"dataset to use"` + Optimize int `arg:"-O" help:"optimization level"` +} +arg.MustParse(&args) +``` + +```shell +$ ./example -h +Usage: [--verbose] [--dataset DATASET] [--optimize OPTIMIZE] [--help] INPUT [OUTPUT [OUTPUT ...]] + +Positional arguments: + INPUT + OUTPUT + +Options: + --verbose, -v verbosity level + --dataset DATASET dataset to use + --optimize OPTIMIZE, -O OPTIMIZE + optimization level + --help, -h print this help message +``` + +### Default values + +```go +var args struct { + Foo string `default:"abc"` + Bar bool +} +arg.MustParse(&args) +``` + +### Default values (before v1.2) + +```go +var args struct { + Foo string + Bar bool +} +arg.Foo = "abc" +arg.MustParse(&args) +``` + +### Combining command line options, environment variables, and default values + +You can combine command line arguments, environment variables, and default values. Command line arguments take precedence over environment variables, which take precedence over default values. This means that we check whether a certain option was provided on the command line, then if not, we check for an environment variable (only if an `env` tag was provided), then if none is found, we check for a `default` tag containing a default value. + +```go +var args struct { + Test string `arg:"-t,env:TEST" default:"something"` +} +arg.MustParse(&args) +``` + +### Arguments with multiple values +```go +var args struct { + Database string + IDs []int64 +} +arg.MustParse(&args) +fmt.Printf("Fetching the following IDs from %s: %q", args.Database, args.IDs) +``` + +```shell +./example

MY-OPTION + -o ONLYSHORT + --help, -h display this help and exit +``` + + +### Embedded structs + +The fields of embedded structs are treated just like regular fields: + +```go + +type DatabaseOptions struct { + Host string + Username string + Password string +} + +type LogOptions struct { + LogFile string + Verbose bool +} + +func main() { + var args struct { + DatabaseOptions + LogOptions + } + arg.MustParse(&args) +} +``` + +As usual, any field tagged with `arg:"-"` is ignored. + +### Supported types + +The following types may be used as arguments: +- built-in integer types: `int, int8, int16, int32, int64, byte, rune` +- built-in floating point types: `float32, float64` +- strings +- booleans +- URLs represented as `url.URL` +- time durations represented as `time.Duration` +- email addresses represented as `mail.Address` +- MAC addresses represented as `net.HardwareAddr` +- pointers to any of the above +- slices of any of the above +- maps using any of the above as keys and values +- any type that implements `encoding.TextUnmarshaler` + +### Custom parsing + +Implement `encoding.TextUnmarshaler` to define your own parsing logic. + +```go +// Accepts command line

`placeholder` tag to control which placeholder text is used in the usage text. + +```go +var args struct { + Input string `arg:"positional" placeholder:"SRC"` + Output []string `arg:"positional" placeholder:"DST"` + Optimize int `arg:"-O" help:"optimization level" placeholder:"LEVEL"` + MaxJobs int `arg:"-j" help:"maximum number of simultaneous jobs" placeholder:"N"` +} +arg.MustParse(&args)

[--foo FOO] + +Options: + --foo FOO + --help, -h display this help and exit +``` + +### Subcommands + +*Introduced in version 1.1.0* + +Subcommands are commonly used in tools that wish to group multiple functions into a single program. An example is the `git` tool: +```shell +$ git checkout [arguments specific to checking out code] +$ git commit [arguments specific to committing] +$ git push [arguments specific to pushing] +``` + +The strings "checkout", "commit", and "push" are different from simple positional arguments because the options available to the user change depending on which subcommand they choose. + +This can be implemented with `go-arg` as follows: + +```go +type CheckoutCmd struct { + Branch string `arg:"positional"` + Track bool `arg:"-t"` +} +type CommitCmd struct { + All bool `arg:"-a"` + Message string `arg:"-m"` +} +type PushCmd struct { + Remote string `arg:"positional"` + Branch string `arg:"positional"` + SetUpstream bool `arg:"-u"` +} +var args struct { + Checkout *CheckoutCmd `arg:"subcommand:checkout"` + Commit *CommitCmd `arg:"subcommand:commit"` + Push *PushCmd `arg:"subcommand:push"` + Quiet bool `arg:"-q"` // this flag is global to all subcommands +} + +arg.MustParse(&args) + +switch { +case args.Checkout != nil: + fmt.Printf("checkout requested for branch %s\n", args.Checkout.Branch) +case args.Commit != nil: + fmt.Printf("commit requested with message \"%s\"\n", args.Commit.Message) +case args.Push != nil: + fmt.Printf("push requested from %s to %s\n", args.Push.Branch, args.Push.Remote) +} +``` + +Some additional rules apply when working with subcommands: +* The `subcommand` tag can only be used with fields that are pointers to structs +* Any struct that contains a subcommand must not contain any positionals + +This package allows to have a program that accepts subcommands, but also does something else +when no subcommands are specified. +If on the other hand you want the program to terminate when no subcommands are specified, +the recommended way is: + +```go +p := arg.MustParse(&args) +if p.Subcommand() == nil { + p.Fail("missing subcommand") +} +``` + +### API Documentation + +https://godoc.org/github.com/alexflint/go-arg + +### Rationale + +There are many command line argument parsing libraries for Go, including one in the standard library, so why build another? + +The `flag` library that ships in the standard library seems awkward to me. Positional arguments must preceed options, so `./prog x --foo=1` does what you expect but `./prog --foo=1 x` does not. It also does not allow arguments to have both long (`--foo`) and short (`-f`) forms. + +Many third-party argument parsing libraries are great for writing sophisticated command line interfaces, but feel to me like overkill for a simple script with a few flags. + +The idea behind `go-arg` is that Go already has an excellent way to describe data structures using structs, so there is no need to develop additional levels of abstraction. Instead of one API to specify which arguments your program accepts, and then another API to get the values of those arguments, `go-arg` replaces both with a single struct. + +### Backward compatibility notes + +Earlier versions of this library required the help text to be part of the `arg` tag. This is still supported but is now deprecated. Instead, you should use a separate `help` tag, described above, which removes most of the limits on the text you can write. In particular, you will need to use the new `help` tag if your help text includes any commas. diff --git a/vendor/github.com/alexflint/go-arg/doc.go b/vendor/github.com/alexflint/go-arg/doc.go new

It doesn't have constant time guarantees like the built-in `regexp` package, but it allows backtracking and is compatible with Perl5 and .NET. You'll likely be better off with the RE2 engine from the `regexp` package and should only use this if you need to write very complex patterns or require compatibility with .NET. + +## Basis of the engine +The engine is ported from the .NET framework's System.Text.RegularExpressions.Regex engine. That engine was open sourced in 2015 under the MIT license. There are some fundamental differences between .NET strings and Go strings that required a bit of borrowing from the Go framework regex engine as well. I cleaned up a couple of the dirtier bits during the port (regexcharclass.cs was terrible), but the parse tree, code emmitted, and therefore patterns matched should be identical. + +## Installing +This is a go-gettable library, so install is easy: + + go get github.com/dlclark/regexp2/... + +## Usage +Usage is similar to the Go `regexp` package. Just like in `regexp`, you start by converting a regex into a state machine via the `Compile` or `MustCompile` methods. They ultimately do the same thing, but `MustCompile` will panic if the regex is invalid. You can then use the provided `Regexp` struct to find matches repeatedly. A `Regexp` struct is safe to use across goroutines. + +```go +re := regexp2.MustCompile(`Your pattern`, 0) +if isMatch, _ := re.MatchString(`Something to match`); isMatch { + //do something +} +``` + +The only error that the `*Match*` methods *should* return is a Timeout if you set the `re.MatchTimeout` field. Any other error is a bug in the `regexp2` package. If you need more details about capture groups in a match then use the `FindStringMatch` method, like so: + +```go +if m, _ := re.FindStringMatch(`Something to match`); m != nil { + // the whole match is always group 0 + fmt.Printf("Group 0: %v\n", m.String()) + + // you can get all the groups too + gps := m.Groups() + + // a group can be captured multiple times, so each cap is separately addressable + fmt.Printf("Group 1, first capture", gps[1].Captures[0].String()) + fmt.Printf("Group 1, second capture", gps[1].Captures[1].String()) +} +``` + +Group 0 is embedded in the Match. Group 0 is an automatically-assigned group that encompasses the whole pattern. This means that `m.String()` is the same as `m.Group.String()` and `m.Groups()[0].String()` + +The __last__ capture is embedded in each group, so `g.String()` will return the same thing as `g.Capture.String()` and `g.Captures[len(g.Captures)-1].String()`. + +If you want to find multiple matches from a single input string you should use the `FindNextMatch` method. For example, to implement a function similar to `regexp.FindAllString`: + +```go +func regexp2FindAllString(re *regexp2.Regexp, s string) []string { + var matches []string + m, _ := re.FindStringMatch(s) + for m != nil { + matches = append(matches, m.String()) + m, _ = re.FindNextMatch(m) + } + return matches +} +``` + +`FindNextMatch` is optmized so that it re-uses the underlying string/rune slice. + +The internals of `regexp2` always operate on `[]rune` so `Index` and `Length` data in a `Match` always reference a position in `rune`s rather than `byte`s (even if the input was given as a string). This is a dramatic difference between `regexp` and `regexp2`. It's advisable to use the provided `String()` methods to avoid having to work with indices. + +## Compare `regexp` and `regexp2` +| Category | regexp | regexp2 | +| --- | --- | --- | +| Catastrophic backtracking possible | no, constant execution time guarantees | yes, if your pattern is at risk you can use the `re.MatchTimeout` field | +| Python-style capture groups `(?Pre)` | yes | no (yes in RE2 compat mode) | +| .NET-style capture groups `(?re)` or `(?'name're)` | no | yes | +| comments `(?#comment)` | no | yes | +| branch numbering reset `(?\|a\|b)` | no | no | +| possessive match `(?>re)` | no | yes | +| positive lookahead `(?=re)` | no | yes | +| negative lookahead `(?!re)` | no | yes | +| positive lookbehind `(?<=re)` | no | yes | +| negative lookbehind `(?re)`) +* change singleline behavior for `$` to only match end of string (like RE2) (see [#24](https://github.com/dlclark/regexp2/issues/24)) +* change the character classes `\d` `\s` and `\w` to match the same characters as RE2. NOTE: if you also use the `ECMAScript` option then this will change the `\s` character class to match ECMAScript instead of RE2. ECMAScript allows more whitespace characters in `\s` than RE2 (but still fewer than the the default behavior). +* allow character escape sequences to have defaults. For example, by default `\_` isn't a known character escape and will fail to compile, but in RE2 mode it will match the literal character `_` + +```go +re := regexp2.MustCompile(`Your RE2-compatible pattern`, regexp2.RE2) +if isMatch, _ := re.MatchString(`Something to match`); isMatch { + //do something +} +``` + +This feature is a work in progress and I'm open to ideas for more things to put here (maybe more relaxed character escaping rules?). + +## ECMAScript compatibility mode +In this mode the engine provides compatibility with the [regex engine](https://tc39.es/ecma262/multipage/text-processing.html#sec-regexp-regular-expression-objects) described in the ECMAScript specification. + +Additionally a Unicode mode is provided which allows parsing of `\u{CodePoint}` syntax that is only when both are provided. + +## Library features that I'm still working on +- Regex split + +## Potential bugs +I've run a battery of tests against regexp2 from various sources and found the debug output matches the .NET engine, but .NET and Go handle strings very differently. I've attempted to handle these differences, but most of my testing deals with basic ASCII with a little bit of multi-byte Unicode. There's a chance that there are bugs in the string handling related to character sets with supplementary Unicode chars. Right-to-Left support is coded, but not well tested either. + +## Find a bug? +I'm open to new issues and pull requests with tests if you find something odd! diff --git a/vendor/github.com/dlclark/regexp2/match.go b/vendor/github.com/dlclark/regexp2/match.go new file mode 100644 index 0000000..1871cff --- /dev/null +++ b/vendor/github.com/dlclark/regexp2/match.go @@ -0,0 +1,347 @@ +package regexp2 + +import ( + "bytes" + "fmt" +) + +// Match is a single regex result match that contains groups and repeated captures +// -Groups +// -Capture +type Match struct { + Group //embeded group 0 + + regex *Regexp + otherGroups []Group + + // input to the match + textpos int + textstart int + + capcount int + caps []int + sparseCaps map[int]int + + // output from the match + matches [][]int + matchcount []int + + // whether we've done any balancing with this match.

In many cases, using a literal newline doesn't affect the file size, and in some cases it may even reduce the file size. + +A typical example is HTML. Whitespace is significant in HTML, meaning that spaces and newlines between or around tags may affect how they are displayed. There is no distinction between a space or a newline and they may be interchanged without affecting the displayed HTML. Remember that a space (0x20) and a newline (0x0A) are both one byte long, so that there is no difference in file size when interchanging them. This minifier removes unnecessary whitespace by replacing stretches of spaces and newlines by a single whitespace character. Specifically, if the stretch of white space characters contains a newline, it will replace it by a newline and otherwise by a space. This doesn't affect the file size, but may help somewhat for debugging or file transmission objectives. + +Another example is JavaScript. Single or double quoted string literals may not contain newline characters but instead need to escape them as `\n`. These are two bytes instead of a single newline byte. Using template literals it is allowed to have literal newline characters and we can use that fact to shave-off one byte! The result is that the minified output contains newlines instead of escaped newline characters, which makes the final file size smaller. Of course, changing from single or double quotes to template literals depends on other factors as well, and this minifier makes a calculation whether the template literal results in a shorter file size or not before converting a string literal. + +## License +Released under the [MIT license](LICENSE.md). + +[1]: http://golang.org/ "Go Language" diff --git a/vendor/github.com/tdewolff/minify/v2/common.go b/vendor/github.com/tdewolff/minify/v2/common.go new file mode 100644 index 0000000..3773a9b --- /dev/null +++ b/vendor/github.com/tdewolff/minify/v2/common.go @@ -0,0 +1,524 @@ +package minify + +import ( + "bytes" + "encoding/base64" + + "github.com/tdewolff/parse/v2" + "github.com/tdewolff/parse/v2/strconv" +) + +var ( + textMimeBytes = []byte("text/plain") + charsetASCIIBytes = []byte("charset=us-ascii") + dataBytes = []byte("data:") + base64Bytes = []byte(";base64") +) + +// Epsilon is the closest number to zero that is not considered to be zero. +var Epsilon = 0.00001 + +// Mediatype minifies a given mediatype by removing all whitespace and lowercasing all parts except strings (which may be case sensitive). +func Mediatype(b []byte) []byte { + j := 0 + inString := false + start, lastString := 0, 0 + for i, c := range b { + if !inString && parse.IsWhitespace(c) { + if start != 0 { + j += copy(b[j:], b[start:i]) + } else { + j += i + } + start = i + 1 + } else if c == '"' { + inString = !inString + if inString { + if i-lastString < 1024 { // ToLower may otherwise slow down minification greatly + parse.ToLower(b[lastString:i]) + } + } else { + lastString = j + (i + 1 - start) + } + } + } + if start != 0 { + j += copy(b[j:], b[start:]) + parse.ToLower(b[lastString:j]) + return b[:j] + } + parse.ToLower(b[lastString:]) + return b +} + +// DataURI minifies a data URI and calls a minifier by the specified mediatype.
