libraryinfo
マクロとscilabライブラリのパスを取得
呼び出し手順
macros = libraryinfo(libraryname) [macros,path] = libraryinfo(libraryname)
引数
- libraryname
文字列 (ライブラリ名)
- macros
文字列行列 (ライブラリの全ての主関数)
- path
文字列 (ライブラリのパス)
説明
指定したScilabライブラリの関数名とパスを取得します. 返される関数名は対応する .sci または .bin のファイルの名前 に一致します. その他の名前は補助関数です.
 | 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:$) - Getting the literal name of the library:
libraryname = xmlGetValues("//scilablib", "name", libpath)
Unloaded library: getting info through its path
If the considered library is not loaded, neither libraryinfo()
nor string() can work.
Provided that we know its libpath, we then can
- get its literal name:
xmlGetValues("//scilablib", "name", libpath+"/lib") - get the column vector of members functions:
functions = xmlGetValues("//scilablib/macro", "name", libpath+"/lib")
例
With libraryinfo(), from the literal library name:
[f, p] = libraryinfo("iolib")
--> [f, p] = libraryinfo("iolib")
p =
SCI\modules\io\macros\
f =
!input !
!unix_g !
!unix_w !
!%_sodload !
!unix_x !
!unix_s !
From the library handle:
// Just for display: iolib // Catch info into variables: p = string(iolib)(1) f = string(iolib)(2:$) 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
