library

library/ is a directory with reusable libraries. Common ideas (with key words):

1. Libraries are categorized by the languages in which they will be used. Bindings MUST be put in <language> directory.

2. Grouping by any other criteria SHOULD be defined by the language committee in <language> directory.

3. The library SHOULD be in use in at least two projects.

   If you are not sure if you should put some library in library/, please contact <language> committee or arcadia-wg@yandex-team.ru.

4. The library SHOULD be portable.

   Please contact <language> committee if you cannot provide usage on all platforms: linux, darwin, windows.

5. The library MUST depend only on a limited list of external components (currently it is util/, contrib/, vendor/, library/).

6. Any code in Arcadia (except contrib/, vendor/ and util/) MAY depend on the library/.

7. The library MUST be accompanied by README.md file and a brief description of the project.

8. The library MUST be accompanied by unit-tests.

9. CPU- or/and RAM-bound algorithms SHOULD provide benchmarks.

10. There MUST be no trade secrets of Yandex in library/: anything that can cause harm on publishing as OpenSource. For example:

    • spam filter rules;
    • coefficients for ML;
    • etc.

11. All OSS (OpenSource Software) ready code MUST be accompanied by macro LICENCE in ya.make.

12. All language specific aspects are defined by <language> committee: see library/<language>/README.md.

13. The library MUST satisfy <language> style-guide.

14. The existing library SHOULD be improved instead of creating a new one - if it is possible.

    Please do not create yet another library for the same thing: just improve existing one.
