Yorick
1.3.3: The help function
Use the help function to get online help. Yorick will parrot the associated DOCUMENT comment to your terminal:
-
> #include "damped.i" > help, damped DOCUMENT damped.i --- compute and output damped sine waves SEE ALSO: damped_wave, q_out defined at: LINE: 3 FILE: /home/icf/munro/damped.i >
Every Yorick function (including help!) has a DOCUMENT comment which describes what it does. Most have SEE ALSO: references to related help topics, so you can navigate your way through a series of related topics.
Whenever you want more details about a Yorick function, the first thing to do is to see what help says about it. Note that, in addition to the DOCUMENT comment, help also reports the full file name and line number where the function is defined. That way, if the comment doesn't tell you what you need to know, you can go to the file and read the complete definition of the function.
The help for help itself, which is the default topic, is of
particular interest, even to a Yorick expert: it tells you the
directory where you can find the include files for all of Yorick's
library functions. Just type help, like it says when Yorick
starts. One of the things you will find in Yorick's directory tree is
a `doc' directory, which contains not only the source for this
manual, but also alphabetized listings of all DOCUMENT comments.
Read the README file in the `doc' directory.
