Defining commands / macros
Without any further explanation this command is used in the following example.
You may have a well illustrated document and you are tired of typing:
\placefigure
[here,force]
[fig:logical name]
{Caption.}
{\externalfigure[filename][width=5cm]}
You could define your own command with a few variables like:
contents
index
commands
definitions
colofon
• logical name
• caption
• file name
Your command definition and call could look something like this:
\define[3]\myputfigure
{\placefigure
[here,force][fig:#1]
{#2}{\externalfigure[#3][width=5cm]}}
\myputfigure{lion}{The Dutch lion is a sentry.}{hass13g}
Between brackets [3] indicates that you want to use three variables #1, #2 and #3. In
the command call \myputfigure you have to input these variables between curly braces.
The result would be:
Very sophisticated commands can be programmed but this is left to your own inventiveness.
In addition to defining commands you can also define \start · · · \stop command pairs.
\definestartstop[...][..,..=..,..]
