Interface between mongoDB and the Next Scripting Framework Ingredients: https://github.com/mongodb/mongo https://github.com/mongodb/mongo-c-driver (requires version v0.3 or better) Compile or obtain mongodb (the database). Compile or obtain the mongo-c-driver (client interface) Assume, Tcl is under /usr/local/ns/lib and the mongo-c-driver is under /usr/local/src/mongo-c-driver/, then configre the nsf interface via ./configure --with-tcl=/usr/local/ns/lib --with-nsf=../../ \ --with-mongo=/usr/local/src/mongo-c-driver/src/,/usr/local/src/mongo-c-driver I had to add MONGO_HAVE_STDINT to the EXTRA_FLAGS of library/mongodb/Makefile.in on MacOS X EXTRA_CFLAGS = @PKG_CFLAGS@ -DMONGO_HAVE_STDINT TODO: remove the hardcoded define flag in Makefile.in In order to run the sample script, * first start the mongdb (eg. mongod) * go to your nsf source directory * make sure, the c-driver libraries are on the library path export DYLD_LIBRARY_PATH=/usr/local/src/mongo-c-driver/:`pwd` * run ./nxsh library/mongodb/example-nsf-mongo.tcl The script is using the low level interface (nsf::mongo) and has a few insert, query and delete statements, some of these are commented out. * run ./nxsh library/mongodb/example-nx-mongo.tcl This example script is using the higher level object oriented interface for nx (nx::mongo). After running the scripts, you should see output like the one below. % /usr/local/bin/mongo MongoDB shell version: 1.9.0-pre- connecting to: test > use tutorial switched to db tutorial > db.persons.find(); -gustaf neumann =============================================================== ~/src/nsf-2.0.0% ./nxsh library/mongodb/example-nsf-mongo.tcl /usr/local/src/tcl8.5.9/unix/tclsh Inserting a few tuples Create an index on name (ascending) Full content _id oid 4d9b0d56e7b0887e00000000 name string Joe projects string abc age integer 23 _id oid 4d9b0d56e7b0887e00000001 name string Gustaf projects string nsf age integer 53 _id oid 4d9b0d56e7b0887e00000002 name string Stefan projects string nsf _id oid 4d9b0d56e7b0887e00000003 name string Franz info object {x integer 203 y integer 102} age integer 29 _id oid 4d9b0d56e7b0887e00000004 name string Victor a array {0 string x 1 string y} age integer 31 Project members of nsf sorted by name _id oid 4d9b0d56e7b0887e00000001 name string Gustaf projects string nsf age integer 53 _id oid 4d9b0d56e7b0887e00000002 name string Stefan projects string nsf Age > 30 _id oid 4d9b0d56e7b0887e00000001 name string Gustaf projects string nsf age integer 53 _id oid 4d9b0d56e7b0887e00000004 name string Victor a array {0 string x 1 string y} age integer 31 Array 'a' contains 'x' _id oid 4d9b0d56e7b0887e00000004 name string Victor a array {0 string x 1 string y} age integer 31 Embedded object has some value (info.y > 100) _id oid 4d9b0d56e7b0887e00000003 name string Franz info object {x integer 203 y integer 102} age integer 29 Nsfmongo Exit =============================================================== ~/src/nsf-2.0.0% ./nxsh library/mongodb/example-nx-mongo.tcl Query: {$query} object {name string Gustaf} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 53 projects array {0 string nsf} Query: {$query} object {name string Gustaf} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 55 projects array {0 string xowiki 1 string nsf} Project members of nsf: Query: {$query} object {projects string nsf} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 55 projects array {0 string xowiki 1 string nsf} _id oid 4d9c224135018d4500000001 name string Stefan projects array {0 string nsf} ::nsf::__#5: Gustaf ::nsf::__#6: Stefan All Persons sorted by name (ascending): Query: {$query} object {} {$orderby} object {name int 1} _id oid 4d9c224135018d4500000003 name string Franz age integer 29 projects array {0 string gtat 1 string annobackend 2 string abc} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 55 projects array {0 string xowiki 1 string nsf} _id oid 4d9c224135018d4500000002 name string Joe age integer 23 projects array {0 string abc} _id oid 4d9c224135018d4500000001 name string Stefan projects array {0 string nsf} ::nsf::__#7: Franz ::nsf::__#8: Gustaf ::nsf::__#9: Joe ::nsf::__#A: Stefan Members of Projects != 'abc' nsf sorted by name desc and age: Query: {$query} object {projects object {{$ne} string abc}} {$orderby} object {name int -1 age int 1} _id oid 4d9c224135018d4500000001 name string Stefan projects array {0 string nsf} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 55 projects array {0 string xowiki 1 string nsf} ::nsf::__#B: Stefan ::nsf::__#C: Gustaf Find persons age > 30: Query: {$query} object {age object {{$gt} integer 30}} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 55 projects array {0 string xowiki 1 string nsf} ::nsf::__#D: Gustaf Find oldies: Query: {$query} object {age object {{$gt} integer 30}} _id oid 4d9c224135018d4500000000 name string Gustaf age integer 55 projects array {0 string xowiki 1 string nsf} ::nsf::__#E: Gustaf Nsfmongo Exit
