3.8 Libraries
-
A library is a collection of SINGULAR
procedures in a file.
-
To load a library into a SINGULAR session, use the
LIB or
load command.
Having loaded a library, its procedures can be used like any built-in
SINGULAR function, and information on the library is obtained
by entering help libname.lib;
-
See SINGULAR libraries, for all libraries currently distributed
with SINGULAR.
-
When writing your own library, it is important to comply with the
guidelines described in this section. Otherwise, due to potential
parser errors, it may not be possible to load the library.
-
Each library consists of a header and a body. The first line
of a library must start with a double slash
//.
-
The library header consists of a version string, a category string,
an info string, and LIB commands. The strings are mandatory. LIB
commands are meant to load the additional libraries used by the
library under consideration.
-
The library body collects the procedures (declared static or not).
-
No line of a library should consist of more than 60 characters.
