|---|
| 4 | |
|---|
| 5 | Some environment variables can be used to change the behaviour of |
|---|
| 6 | \e libcaca without having to modify the program which uses them. These |
|---|
| 7 | variables are: |
|---|
| 8 | |
|---|
| 9 | \li \b CACA_DRIVER: set the backend video driver. In order of preference: |
|---|
| 10 | - \c conio uses the DOS conio.h interface. |
|---|
| 11 | - \c ncurses uses the ncurses library. |
|---|
| 12 | - \c slang uses the S-Lang library. |
|---|
| 13 | - \c x11 uses the native X11 driver. |
|---|
| 14 | - \c gl uses freeglut and opengl libraries. |
|---|
| 15 | - \c raw outputs to the standard output instead of rendering the |
|---|
| 16 | canvas. This is can be used together with cacaserver. |
|---|
| 17 | |
|---|
| 18 | \li \b CACA_GEOMETRY: set the video display size. The format of this |
|---|
| 19 | variable must be \c XxY, with \c X and \c Y being integer values. This |
|---|
| 20 | option currently works with the X11 and GL drivers. |
|---|
| 21 | |
|---|
| 22 | \li \b CACA_FONT: set the rendered font. The format of this variable is |
|---|
| 23 | implementation dependent, but since it currently only works with the |
|---|
| 24 | X11 driver, an X11 font name such as \c fixed or \c 5x7 is expected. |
