This repository holds supplementary Go libraries for text processing, many involving Unicode.
This repo uses Semantic versioning (http://semver.org/), so
- MAJOR version when you make incompatible API changes,
- MINOR version when you add functionality in a backwards-compatible manner, and
- PATCH version when you make backwards-compatible bug fixes.
Until version 1.0.0 of x/text is reached, the minor version is considered a major version. So going from 0.1.0 to 0.2.0 is considered to be a major version bump.
A major new CLDR version is mapped to a minor version increase in x/text. Any other new CLDR version is mapped to a patch version increase in x/text.
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.
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.

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.
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.

- updating unversioned source files.
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.
To update a Unicode version run
UNICODE_VERSION=x.x.x go generate
where x.x.x must correspond to a directory in http://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
http://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.
