[Haskell-cafe] recommendation for (best) sqlite3 bindings
Hello! We are looking for recommendation which Haskell bindings for sqlite3 to use for destkop GUI app where we want, among other things to store *.png and/or *.jpg images. (Yeah, I know about the hint to store iamges in the filesystem and just store filepaths in the db, but for portability reasons so that user can easily carry/backup database, we want everything stored in one file.) By looking at Hackage, it seems there are 3 candidates: 1) sqlite - bindings by Galois (http://hackage.haskell.org/package/sqlite) - looks quite complete low-level interface 2) direct-sqlite - it says It is not as complete as bindings-sqlite3 (1), but is slightly higher-level...it supports strings encoded as UTF8, and BLOBs represented as ByteStrings. and 3) HDBC-sqlite3 - higher level but without support for BLOBs. Now, based on the above it looks that 2) is the best one - not high-level as 2), but adding BLOBs support which, iirc, is missing in HDBC. Otoh, having highr-level abstraction ala HDBC is nice, although at the moment we believe that we won't have need to go to PostgreSQL since it means that setup would be greatly complicated for the end-user, so we're staying focused on Sqlite3. I know there are also Takusen HSQL, but based on my past experiences when watching those two projects, it seems they aren not supported as well as the above itemized ones. Any recommendation? May I add that, according to the recent Merge hsql and HDBC -- there can only be one! thread, I can only +1 for having slight less more complete database packages.

John == John Goerzen jgoer...@complete.org writes: Hello John, John I would say that database interactions are typically limited to a John small part of code. In small programs, I generally have a DB John module that does the queries, and marshals everything to/from the John rich Haskell types I define. Any possible type issues are thus John constrained to that small part of code. That's right. However, I envision application for which a significant part would require querying (kind of research base for querying common stuff in thousands of records.) John HDBC is a low-level abstraction, which can be used on its own or, John of course, as a layer underlying HaskellDB or some such. I do not John dispute the use of tools such as HaskellDB or others that try to John automate the business of representing a database's schema -- and John queries against it -- using a language's type system. There are a John lot of these systems in a lot of languages. I've used some of John them. Have you maybe tried Takusen (HaskellDB which you reference above does not seem very much alive)? John And, almost universally, they annoy me. I find it takes longer to John write code with them than without, and often they have issues John representing some query that I know I can do easily in SQL but John maybe can't as easy in the toolkit. As an example, when I last John looked at HaskellDB in 2005, I found that it was impossible to do John a SELECT without a DISTINCT [1]. There are many situations where John such a thing is necessary, so I had to discard it for my projects. Hmm, that's interesting to hear...I'm curious what could be reply from Takusen devs... John HDBC is more similar to Perl's DBI or Python's DB-API (or perhaps John a sane version of JDBC). It is a standard interface to SQL RDBMS John engines that provides some tools for marshaling data back and John forth, but generally leaves you to construct the queries. Well, that's not too bad... John So, this was not intended as an HDBC commercial, just more of a John braindump as to why I wrote it. Hope it helps. Sure, it helps. Thanks a lot for your input. Otoh, I believe that, considering it is mentioned in RWH, HDBC does not need much commercial, just contrary, you can expect new feature requests From the new army of Haskell developers cultivated by the book :-) I'll e.g. open ticket for BLOB support :-D John HDBC is actively used in mission-critical applications where I John work. We use both the PostgreSQL and ODBC backends in production. John We even use the ODBC backend along with the particularly nefarious John ODBC interface for the Progress 4GL database. I use the Sqlite3 John backend quite a bit in my own personal projects, such as hpodder John and twidge. Database abstraction offered by HDBC is very nice feature allowing one to change back-end driver without too much hassle, so I'll try to investigate a bit about possible BLOB support on HDBC-level.

[Haskell-cafe] databases in Haskell type-safety
Hi! I'd like to use sqlite3 as application storage in my haskell project... Browsing the available database options in Haskell it seems that: a) HSQL is dead (hackage reports build-failure with 6.8 6.10) b) haskelldb is also not in a good shape - build fails with 6.8 6.10 For Haskell-newbie as myself, it looks that haskelldb is the one which provide(ed)s the most secure API (I was reading draft paper about MetaHDBC but, apparently, the type inference support in open-source databases is poor and that's why, according to the author This is unfortunately as it makes MetaHDBC a lot less valuable. What remains is: c) Takusen which is also not up-to-date (it fails with 6.10) and d) HDBC and sqlite bindings which are the only packages which build with 6.10. However options in d) do not offer, afaik, type-safety which is emblem of Haskell language, so I wonder how much this could be the problem for real-world usage? So, considering that HDBC nicely abstracts API enabling one to easily switch from e.g. Sqlite3 to Postgres, and it is used as in example for database programming, it seems as logical (and the only) choice for Haskell database programming in a real-world? I'm not familiar with Takusen which says: Takusen's unique selling point is safety and efficiency... and I would appreciate if someone could shed some more light to its 'safety' and the present status?

[Haskell-cafe] Haskell and i18n (aka gettext) support
Dear Haskellers, Some time ago the question was asked on gtk2hs mailing list about how to work with *.po files, i.e. how to make Haskell program i18n-aware. (see http://thread.gmane.org/gmane.comp.lang.haskell.gtk2hs/592) The answer was that Gtk2hs does not have gettext support (http://article.gmane.org/gmane.comp.lang.haskell.gtk2hs/593), but that it is something which is needed (http://article.gmane.org/gmane.comp.lang.haskell.gtk2hs/598) but it's not clear how to do it. As potential 'solution the 'i18n' package was mentioned (http://hackage.haskell.org/cgi-bin/hackage-scripts/package/i18n) with the remark that its API is not the most beautiful. Moreover, by looking at i18n's *.cabal file one can see it is labelled as 'experimental'. Moreover, if one inspects GNU gettext manual one can see the list of languages with the explanations how to make the program i18n-ready. The list is, unfortunately, without Haskell: * C: C, C++, Objective C * sh: sh - Shell Script * bash: bash - Bourne-Again Shell Script * Python: Python * Common Lisp: GNU clisp - Common Lisp * clisp C: GNU clisp C sources * Emacs Lisp: Emacs Lisp * librep: librep * Scheme: GNU guile - Scheme * Smalltalk: GNU Smalltalk * Java: Java * C#: C# * gawk: GNU awk * Pascal: Pascal - Free Pascal Compiler * wxWidgets: wxWidgets library * YCP: YCP - YaST2 scripting language * Tcl: Tcl - Tk's scripting language * Perl: Perl * PHP: PHP Hypertext Preprocessor * Pike: Pike * GCC-source: GNU Compiler Collection sources Real World Haskell book is at the door and it will bring army of new Haskell programmers to find out that Haskell misses one of the important items in its battery set. :-( So, we think that i18n issue or proper gettext support should have a stable and well documented implementation and has to be part of batteries included or Haskell Platform (http://www.haskell.org/haskellwiki/Haskell_Platform) However, don't ask me 'how' :-D We got some hints on the IRC yesterday, but considering it is important issue for the whole Haskell community, we are bringing it here so that smarter and more skillful (than ourselves) souls can discuss it.

Please let me know if my impression of its stability and track record are wrong. I'll try, although I cannot mimic proper scaling on my localhost with few small projects. Also - if the Haskell community adopts Redmine, that itself could give it a big push. I fully agree and hope someone more qualified (from Haskell community) will take a look too.

I just want to use Haddock, not modify it. Pls. tell me if you want it via email.
