+
+> **NOTE:** As Chroma has just been released, its API is still in flux. That said, the high-level interface should not change significantly.
+
+Chroma takes source code and other structured text and converts it into syntax
+highlighted HTML, ANSI-coloured text, etc.
+
+Chroma is based heavily on [Pygments](http://pygments.org/), and includes
+translators for Pygments lexers and styles.

+
+## Using the library
+
+Chroma, like Pygments, has the concepts of
+[lexers](https://github.com/alecthomas/chroma/tree/master/lexers),
+[formatters](https://github.com/alecthomas/chroma/tree/master/formatters) and
+[styles](https://github.com/alecthomas/chroma/tree/master/styles).
+
+Lexers convert source text into a stream of tokens, styles specify how token
+types are mapped to colours, and formatters convert tokens and styles into
+formatted output.
+
+A package exists for each of these, containing a global `Registry` variable
+with all of the registered implementations. 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`).
+- `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())
+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:
+
+```
+python3 ~/Projects/chroma/_tools/pygments2chroma.py \
+  pygments.lexers.jvm.KotlinLexer \
+  > ~/Projects/chroma/lexers/kotlin.go \
+  && gofmt -s -w ~/Projects/chroma/lexers/*.go
+```
+
+See notes in [pygments-lexers.go](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.
+
+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. It can be installed with:
+
+```
+go get -u github.com/alecthomas/chroma/cmd/chroma
+```
+
+## 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 Perl6'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.

+These pieces of code were ported from dotnet/corefx:
+
+syntax/charclass.go (from RegexCharClass.cs): ported to use the built-in Go unicode classes.  Canonicalize is 
+    a direct port, but most of the other code required large changes because the C# implementation 
+    used a string to represent the CharSet data structure and I cleaned that up in my implementation.
+
+syntax/code.go (from RegexCode.cs): ported literally with various cleanups and layout to make it more Go-ish.
+
+syntax/escape.go (from RegexParser.cs): ported Escape method and added some optimizations.  Unescape is inspired by 
+    the C# implementation but couldn't be directly ported because of the lack of do-while syntax in Go.
+
+syntax/parser.go (from RegexpParser.cs and RegexOptions.cs): ported parser struct and associated methods as 
+    literally as possible. Several language differences required changes.  E.g. lack pre/post-fix increments as 
+    expressions, lack of do-while loops, lack of overloads, etc.
+
+syntax/prefix.go (from RegexFCD.cs and RegexBoyerMoore.cs): ported as literally as possible and added support
+    for unicode chars that are longer than the 16-bit char in C# for the 32-bit rune in Go.
+
+syntax/replacerdata.go (from RegexReplacement.cs): conceptually ported and re-organized to handle differences 
+    in charclass implementation, and fix odd code layout between RegexParser.cs, Regex.cs, and RegexReplacement.cs.
+
+syntax/tree.go (from RegexTree.cs and RegexNode.cs): ported literally as possible.
+
+syntax/writer.go (from RegexWriter.cs): ported literally with minor changes to make it more Go-ish.
+
+match.go (from RegexMatch.cs): ported, simplified, and changed to handle Go's lack of inheritence.
+
+regexp.go (from Regex.cs and RegexOptions.cs): conceptually serves the same "starting point", but is simplified 
+    and changed to handle differences in C# strings and Go strings/runes.  
+
+replace.go (from RegexReplacement.cs): ported closely and then cleaned up to combine the MatchEvaluator and 
+    simple string replace implementations.
+
+runner.go (from RegexRunner.cs): ported literally as possible.
+
+regexp_test.go (from CaptureTests.cs and GroupNamesAndNumbers.cs): conceptually ported, but the code was

+# regexp2 - full featured regular expressions for Go
+Regexp2 is a feature-rich RegExp engine for Go.  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()`.
+
+## 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 `(P<name>re)` | yes | no |
+| .NET-style capture groups `(<name>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)` | no | yes |
+| back reference `\1` | no | yes |
+| named back reference `\k'name'` | no | yes |
+| named ascii character class `[[:foo:]]`| yes | no |
+| conditionals `((expr)yes\|no)` | no | yes |
+
+## 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!

+    Let U be the set of Unicode character values and let L be the lowercase
+    function, mapping from U to U. To perform case insensitive matching of
+    character sets, we need to be able to map an interval I in U, say
+
+        I = [chMin, chMax] = { ch : chMin <= ch <= chMax }
+
+    to a set A such that A contains L(I) and A is contained in the union of
+    I and L(I).
+
+    The table below partitions U into intervals on which L is non-decreasing.
+    Thus, for any interval J = [a, b] contained in one of these intervals,
+    L(J) is contained in [L(a), L(b)].
+
+    It is also true that for any such J, [L(a), L(b)] is contained in the
+    union of J and L(J). This does not follow from L being non-decreasing on
+    these intervals. It follows from the nature of the L on each interval.
+    On each interval, L has one of the following forms:
+
+        (1) L(ch) = constant            (LowercaseSet)
+        (2) L(ch) = ch + offset         (LowercaseAdd)
+        (3) L(ch) = ch | 1              (LowercaseBor)
+        (4) L(ch) = ch + (ch & 1)       (LowercaseBad)
+
+    It is easy to verify that for any of these forms [L(a), L(b)] is
+    contained in the union of [a, b] and L([a, b]).

+// Implementation notes:
+//
+// Since the node tree is a temporary data structure only used
+// during compilation of the regexp to integer codes, it's
+// designed for clarity and convenience rather than
+// space efficiency.
+//
+// RegexNodes are built into a tree, linked by the n.children list.
+// Each node also has a n.parent and n.ichild member indicating
+// its parent and which child # it is in its parent's list.
+//
+// RegexNodes come in as many types as there are constructs in
+// a regular expression, for example, "concatenate", "alternate",
+// "one", "rept", "group". There are also node types for basic
+// peephole optimizations, e.g., "onerep", "notsetrep", etc.
+//
+// Because perl 5 allows "lookback" groups that scan backwards,
+// each node also gets a "direction". Normally the value of
+// boolean n.backward = false.
+//
+// During parsing, top-level nodes are also stacked onto a parse
+// stack (a stack of trees). For this purpose we have a n.next
+// pointer. [Note that to save a few bytes, we could overload the
+// n.parent pointer instead.]
+//
+// On the parse stack, each tree has a "role" - basically, the
+// nonterminal in the grammar that the parser has currently
+// assigned to the tree. That code is stored in n.role.
+//
+// Finally, some of the different kinds of nodes have data.
+// Two integers (for the looping constructs) are stored in
+// n.operands, an an object (either a string or a set)
+// is stored in n.data

Here are some examples:\n\nExample (Java):\n\n     import com.google.type.Color;\n\n     // ...\n     public static java.awt.Color fromProto(Color protocolor) {\n       float alpha = protocolor.hasAlpha()\n           ? protocolor.getAlpha().getValue()\n           : 1.0;\n\n       return new java.awt.Color(\n           protocolor.getRed(),\n           protocolor.getGreen(),\n           protocolor.getBlue(),\n           alpha);\n     }\n\n     public static Color toProto(java.awt.Color color) {\n       float red = (float) color.getRed();\n       float green = (float) color.getGreen();\n       float blue = (float) color.getBlue();\n       float denominator = 255.0;\n       Color.Builder resultBuilder =\n           Color\n               .newBuilder()\n               .setRed(red / denominator)\n               .setGreen(green / denominator)\n               .setBlue(blue / denominator);\n       int alpha = color.getAlpha();\n       if (alpha != 255) {\n         result.setAlpha(\n             FloatValue\n                 .newBuilder()\n                 .setValue(((float) alpha) / denominator)\n                 .build());\n       }\n       return resultBuilder.build();\n     }\n     // ...\n\nExample (iOS / Obj-C):\n\n     // ...\n     static UIColor* fromProto(Color* protocolor) {\n        float red = [protocolor red];\n        float green = [protocolor green];\n        float blue = [protocolor blue];\n        FloatValue* alpha_wrapper = [protocolor alpha];\n        float alpha = 1.0;\n        if (alpha_wrapper != nil) {\n          alpha = [alpha_wrapper value];\n        }\n        return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];\n     }\n\n     static Color* toProto(UIColor* color) {\n         CGFloat red, green, blue, alpha;\n         if (![color getRed:\u0026red green:\u0026green blue:\u0026blue alpha:\u0026alpha]) {\n           return nil;\n         }\n         Color* result = [[Color alloc] init];\n         [result setRed:red];\n         [result setGreen:green];\n         [result setBlue:blue];\n         if (alpha \u003c= 0.9999) {\n           [result setAlpha:floatWrapperWithValue(alpha)];\n         }\n         [result autorelease];\n         return result;\n    }\n    // ...\n\n Example (JavaScript):\n\n    // ...\n\n    var protoToCssColor = function(rgb_color) {\n       var redFrac = rgb_color.red || 0.0;\n       var greenFrac = rgb_color.green || 0.0;\n       var blueFrac = rgb_color.blue || 0.0;\n       var red = Math.floor(redFrac * 255);\n       var green = Math.floor(greenFrac * 255);\n       var blue = Math.floor(blueFrac * 255);\n\n       if (!('alpha' in rgb_color)) {\n          return rgbToCssColor_(red, green, blue);\n       }\n\n       var alphaFrac = rgb_color.alpha.value || 0.0;\n       var rgbParams = [red, green, blue].join(',');\n       return ['rgba(', rgbParams, ',', alphaFrac, ')'].join('');\n    };\n\n    var rgbToCssColor_ = function(red, green, blue) {\n      var rgbNumber = new Number((red \u003c\u003c 16) | (green \u003c\u003c 8) | blue);\n      var hexString = rgbNumber.toString(16);\n      var missingZeros = 6 - hexString.length;\n      var resultBuilder = ['#'];\n      for (var i = 0; i \u003c missingZeros; i++) {\n         resultBuilder.push('0');\n      }\n      resultBuilder.push(hexString);\n      return resultBuilder.join('');\n    };\n\n    // ...",
