all: prepare for Unicode 15.0.0

internal/gen has never been updated for Go 1.17's //go:build tags.
Do that, and add the entry for Unicode 15.0.0.

Unicode 15.0.0 will change 9fff to be a CJK ideograph, which will
break the unicode/runenames example test.
Delete that part of the example.

For golang/go#55079.

Go Text

Go Reference

This repository holds supplementary Go libraries for text processing, many involving Unicode.

CLDR Versioning

It is important that the Unicode version used in x/text matches the one used by your Go compiler. The x/text repository supports multiple versions of Unicode and will match the version of Unicode to that of the Go compiler. At the moment this is supported for Go compilers from version 1.7.

Download/Install

The easiest way to install is to run go get -u golang.org/x/text. You can also manually git clone the repository to $GOPATH/src/golang.org/x/text.

Contribute

To submit changes to this repository, see http://golang.org/doc/contribute.html.

To generate the tables in this repository (except for the encoding tables), run go generate from this directory. By default tables are generated for the Unicode version in core and the CLDR version defined in golang.org/x/text/unicode/cldr.

Running go generate will as a side effect create a DATA subdirectory in this directory, which holds all files that are used as a source for generating the tables. This directory will also serve as a cache.

Testing

Run

go test ./...

from this directory to run all tests. Add the “-tags icu” flag to also run ICU conformance tests (if available). This requires that you have the correct ICU version installed on your system.

TODO:

  • updating unversioned source files.

Generating Tables

To generate the tables in this repository (except for the encoding tables), run go generate from this directory. By default tables are generated for the Unicode version in core and the CLDR version defined in golang.org/x/text/unicode/cldr.

Running go generate will as a side effect create a DATA subdirectory in this directory which holds all files that are used as a source for generating the tables. This directory will also serve as a cache.

Versions

To update a Unicode version run

UNICODE_VERSION=x.x.x go generate

where x.x.x must correspond to a directory in https://www.unicode.org/Public/. If this version is newer than the version in core it will also update the relevant packages there. The idna package in x/net will always be updated.

To update a CLDR version run

CLDR_VERSION=version go generate

where version must correspond to a directory in https://www.unicode.org/Public/cldr/.

Note that the code gets adapted over time to changes in the data and that backwards compatibility is not maintained. So updating to a different version may not work.

The files in DATA/{iana|icu|w3|whatwg} are currently not versioned.
