+
+> **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.

+<a id="markdown-try-it" name="try-it"></a>
+## Try it
+
+Try out various languages and styles on the [Chroma Playground](https://swapoff.org/chroma/playground/).
+
+<a id="markdown-using-the-library" name="using-the-library"></a>
+## 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.
+
+<a id="markdown-quick-start" name="quick-start"></a>
+### 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")
+```
+
+<a id="markdown-identifying-the-language" name="identifying-the-language"></a>
+### 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)
+```
+
+<a id="markdown-formatting-the-output" name="formatting-the-output"></a>
+### 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)
+```
+
+<a id="markdown-the-html-formatter" name="the-html-formatter"></a>
+### 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())
+err := formatter.WriteCSS(w, style)
+```
+

+## More detail
+
+<a id="markdown-lexers" name="lexers"></a>
+### 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.
+
+<a id="markdown-formatters" name="formatters"></a>
+### 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.
+
+<a id="markdown-styles" name="styles"></a>
+### 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/).
+
+<a id="markdown-command-line-interface" name="command-line-interface"></a>
+## 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`.
+
+<a id="markdown-whats-missing-compared-to-pygments" name="whats-missing-compared-to-pygments"></a>
+## 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.

+# Lexer tests
+
+The tests in this directory feed a known input `testdata/<name>.actual` into the parser for `<name>` and check
+that its output matches `<name>.exported`.
+
+It is also possible to perform several tests on a same parser `<name>`, by placing know inputs `*.actual` into a
+directory `testdata/<name>/`.
+
+## Running the tests
+
+Run the tests as normal:
+```go
+go test ./lexers
+```
+
+## Update existing tests
+When you add a new test data file (`*.actual`), you need to regenerate all tests. That's how Chroma creates the `*.expected` test file based on the corresponding lexer.
+
+To regenerate all tests, type in your terminal:
+
+```go
+RECORD=true go test ./lexers
+```
+
+This first sets the `RECORD` environment variable to `true`. Then it runs `go test` on the `./lexers` directory of the Chroma project.
+
+(That environment variable tells Chroma it needs to output test data. After running `go test ./lexers` you can remove or reset that variable.)
+
+### Windows users
+Windows users will find that the `RECORD=true go test ./lexers` command fails in both the standard command prompt terminal and in PowerShell.
+
+Instead we have to perform both steps separately:
+
+- Set the `RECORD` environment variable to `true`.
+	+ In the regular command prompt window, the `set` command sets an environment variable for the current session: `set RECORD=true`. See [this page](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line) for more.
+	+ In PowerShell, you can use the `$env:RECORD = 'true'` command for that. See [this article](https://mcpmag.com/articles/2019/03/28/environment-variables-in-powershell.aspx) for more.
+	+ You can also make a persistent environment variable by hand in the Windows computer settings. See [this article](https://www.computerhope.com/issues/ch000549.htm) for how.
+- When the environment variable is set, run `go tests ./lexers`.
+
+Chroma will now regenerate the test files and print its results to the console window.
