libraryinfo

retorna macros e endereço de uma biblioteca Scilab

Seqüência de Chamamento

macros = libraryinfo(libraryname)
[macros,path] = libraryinfo(libraryname)

Parâmetros

libraryname

string (nome da biblioteca)

macros

uma matriz de strings (todas as funções principais da biblioteca)

path

um string (endereço da biblioteca)

Descrição

Retorna nomes de funções e o endereço de uma biblioteca Scilab. Os nomes de funções são aqueles que correspondem aos nomes de arquivo associados .sci ou .bin. Os outros são funções subsidiárias.

Only loaded libraries can be addressed by libraryinfo().

Getting some library info from its handle

libraryinfo() works from the literal name of the library. In some cases, we may have only its handle, defined when loading the library. For instance, libraryinfo("iolib") works, libraryinfo(iolib) does not. How to use the handle to get any info? Let's go on with the iolib example:

  • Getting the path: libpath = string(iolib)(1)
  • Getting the column vector of members functions: functions = string(iolib)(2:$)
  • Getting the literal name of the library: libraryname = xmlGetValues("//scilablib", "name", libpath)

Unloaded library: getting info through its path

If the considered library is not loaded, neither libraryinfo() nor string() can work.

Provided that we know its libpath, we then can

  • get its literal name: xmlGetValues("//scilablib", "name", libpath+"/lib")
  • get the column vector of members functions: functions = xmlGetValues("//scilablib/macro", "name", libpath+"/lib")

Exemplos

With libraryinfo(), from the literal library name:

[f, p] = libraryinfo("iolib")
--> [f, p] = libraryinfo("iolib")
 p  =
 SCI\modules\io\macros\

 f  =
!input      !
!unix_g     !
!unix_w     !
!%_sodload  !
!unix_x     !
!unix_s     !

From the library handle:

// Just for display:
iolib

// Catch info into variables:
p = string(iolib)(1)
f = string(iolib)(2:$)
libname = xmlGetValues("//scilablib", "name", p+"/lib")
--> // Just for display:
--> iolib

 iolib  =
Functions files location : SCI\modules\io\macros\.
input  unix_g  unix_w  %_sodload  unix_x  unix_s

--> // Catch info into variables:
--> p = string(iolib)(1)
 p  =
 SCI\modules\io\macros\

--> f = string(iolib)(2:$)
 f  =
!input      !
!unix_g     !
!unix_w     !
!%_sodload  !
!unix_x     !
!unix_s     !

--> libname = xmlGetValues("//scilablib", "name", p+"/lib")
 libname  =
 iolib

For a not-loaded library, from its path:

path = fullpath("SCI/modules/scicos_blocks/macros/Hydraulics");
libname = xmlGetValues("//scilablib", "name", path+"/lib")
functions = xmlGetValues("//scilablib/macro", "name", path+"/lib")
Hydraulicslib  // not-loaded (Xcos must have not been run)
--> libname = xmlGetValues("//scilablib", "name", path+"/lib")
 libname  =
 Hydraulicslib

--> functions = xmlGetValues("//scilablib/macro", "name", path+"/lib")
 functions  =
!Bache          !
!Flowmeter      !
!PerteDP        !
!PuitsP         !
!SourceP        !
!VanneReglante  !

--> Hydraulicslib
Undefined variable: Hydraulicslib
