Variables Twiki

Las secuencias de texto se expanden sobre la marcha para mostrarte datos o informacion del sistema

Vista previa

TWikiVariables son secuencias de texto - %VARIABLE% - que se expanden siempre que se abre una pagina. Las variables son sustituidas por sus valores reales: datos almacenados, o informacion del sistema (como la fecha, o el usuario actual). Hay variables predefinidas, y variables con preferencia que tu marcaste. Tu tambien puedes crear tus propias variables, cpn nuevos nombres y valores.

Variables predefinidas

Muchas de las variables predefinidas vuelven a poner los valores que se definieron cuando TWiki fue instalado, o los cojen de la informacion del sistema (como el usuario actual, o la fecha y la hora). Muchas de estas variables te dejan controlar como se vera el formato final.

Fijando preferencias

• The syntax for Preferences variables is the same anywhere in TWiki. In Edit mode, from the start of a new line:
  [6 spaces] * [space] Set [space] VARIABLENAME [space] = [value]
  Example:
  • Set VARIABLENAME = value

Creando tus propias variables

• You can add your own preference variables for an entire site, a single web, or a single topic, using the standard syntax. Whatever you include in your variable will be expanded on display, and treated exactly as if it had been written out. So you can place formatted text, page links, image paths.

Example: Create a custom logo variable

• To place a logo anywhere in a web by typing %MYLOGO%, simply define the variable on the web's WebPreferences page. You also have to upload logo.gif - this can be done by attaching a file to LogoTopic (any topic name you choose):
  • Set MYLOGO = %PUBURL%/%MAINWEB%/LogoTopic/logo.gif
