[Monetdb-developers] php module compiling

by Arjan Scherpenisse

The following code compiles the php module: gcc -fpic -DCOMPILE_DL=1 `php-config --includes` `monet-config --cflags` -c -o monetdb.o php_monetdb.c gcc -shared `php-config --libs` `monet-config --libs` -lMapi -rdynamic -o monetdb.so monetdb.o And installing: cp monetdb.so `php-config --extension-dir` Maybe someone (stefan?) with more knowledge of the build process can integrate this stuff. The only thing is that monet-config --cflags does not list $MONET_PREFIX/include/MonetDB/C as include dir, which is the directory Mapi.h resides in. Can this be fixed, or is this done on purpose? -- Arjan Scherpenisse Centrum voor Wiskunde en Informatica, Amsterdam, the Netherlands

[Monetdb-developers] readline things

by Arjan Scherpenisse

Hi, I, as a frequent MapiClient user, have added some convenience functions to the readline interface over time: - commandline-selectable "save/load history" option (default=off). - basic 'tab' command completion (for SQL only, as of now). Completes on table names and SQL commands. Could be improved, but this already saves a lot of typing. I have added the .mx code and patch for MapiClient.mx and Makefile.ag If someone could look over this code; it would be nice to have it in cvs. -- Arjan Scherpenisse Centrum voor Wiskunde en Informatica, Amsterdam, the Netherlands Index: MapiClient.mx =================================================================== RCS file: /cvsroot/monetdb/MonetDB/src/mapi/clients/C/MapiClient.mx,v retrieving revision 1.57 diff -u -r1.57 MapiClient.mx --- MapiClient.mx 11 May 2004 11:03:04 -0000 1.57 +++ MapiClient.mx 2 Jun 2004 14:56:16 -0000 @@ -56,6 +56,7 @@ -t & --trace & trace Monet interaction \\ -T & --time & time commands \\ -u user & --user=user & user id \\ + -H & --history & load/save cmdline history (default off) \\ -? & --help & show this usage message \\ \end{tabular} @@ -83,6 +84,7 @@ #ifdef HAVE_LIBREADLINE #include <readline/readline.h> #include <readline/history.h> +#include "ReadlineTools.h" #endif #ifndef S_ISCHR @@ -805,6 +807,7 @@ fprintf(stderr, " -t | --trace /* trace Monet interaction */\n");
