This repository holds supplementary Go libraries for text processing, many involving Unicode.
# Semantic Versioning
This repo uses Semantic versioning (http://semver.org/), so
1. MAJOR version when you make incompatible API changes,
1. MINOR version when you add functionality in a backwards-compatible manner,
and
1. PATCH version when you make backwards-compatible bug fixes.
A Unicode major and minor version bump is mapped to a major version bump in
x/text.
A path version bump in Unicode is mapped to a minor version bump in x/text.
Note that, consistent with the definitions in semver, 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.
# 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.
## Versions
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.
