Diky relacnim rouram muzeme mit dve mnoziny not a pak s nimi provadet operace jako je sjednoceni nebo prunik, to dava mixovani hudby uplne novy rozmer!

What Relational pipes are?

Relational pipes are an open data format designed for streaming structured data between two processes. Simultaneously with the format specification, we are also developing a reference implementation (libraries and tools) as a free software. Although we believe in the specification-first (or contract-first) approach, we always look and check, whether the theoretic concepts are feasible and whether they can be reasonably and reliably implemented. So befeore publishing any new specification or its version, we will verify it by creating a reference implementation at least in one programming language.

More generally, Relational pipes are a philosophical continuation of the classic *NIX pipelines and the relational model.

What Relational pipes are not?

Relational pipes respect the existing ecosystem and are rather an improvement or supplement than a replacement. So the Relational pipes are not a:

• Shell – we use existing shells (e.g. GNU Bash), work with any shell and even without a shell (e.g. as a stream format passed through a network or stored in a file).
• Terminal emulator – same as with shells, we use existing terminals and we can use Relational pipes also outside any terminal; if we interact with the terminal, we use standard means like Unicode, ANSI escape sequences etc.
• IDE – we can use standard *NIX tools as an IDE (GNU Screen, Emacs, Make etc.) or any other IDE.
• Programming language – Relational pipes are language-independent data format and can be produced or consumed in any programming language.
• Query language – although some of our tools are doing queries, filtering or transformations, we are not inventing a new query language – instead, we use existing languages like SQL, XPath, Guile/Scheme, AWK or regular expressions.
• Database system, DBMS – we focus on the stream processing rather than data storage. Although sometimes it makes sense to redirect data to a file and continue with the processing later.

Každopádně bych ti měl za zlé, že tam nejsou žádné instalační balíčky.

[xkucf03]

To je pravda. Na seznamu úkolů to samozřejmě je, ale zatím na to nepřišla řada. Nicméně pro koncové uživatele to zatím úplně není (API se ještě může trochu měnit – zpětná kompatibilita bude udržována až od v1.0) a pro případné vývojáře mi přijde lepší kompilace ze zdrojových kódů.

Ale zkusím těm balíčkům trochu zvýšit prioritu :-)

Můžeš instalací verzovaných sdílených knihoven do standardní cesty. Tohle je jeden z důvodů, proč jsem pro ti to nezabalil do Fedory.
