- Updated August 6, 2012
- Bug fix for use on FreeBSD 8.x supplied by Devin Teske. Thanks!
- What is this?
- This is a sh/awk wrapper script to give the ports options setting screen
- more features:
- Extended descriptions for FreeBSD 8.3+ and 9.0+. Port maintainers can
- make descriptions longer and more explanatory.
- Auto-sizing of the option screen to fit the terminal window. Wider or
- taller windows can display more of the descriptions, or more options.
- Windows smaller than 80x24 also work.
- Older versions of dialog(1) had a bug in displaying descriptions that
- are longer than the available space. When an old version of dialog is
- detected, descriptions are cut to the available space. These earlier
- versions of dialog did not support the --item-help feature used to
- show extended descriptions, so only the trimmed description will be
- shown. Descriptions that have been trimmed will still end in a "+" to
- indicate that part of it has been trimmed.
- Installation
- Edit /etc/make.conf:
- DIALOG="/usr/ports/Tools/scripts/dialogwrapper.sh"
- Testing long descriptions
- Open a terminal window and resize it, making it narrower than the
- default 80 columns. Try 60 or 70 columns.
- su to root and run 'make config' for a port that uses long descriptions.
- For example:
- # cd /usr/ports/audio/xmms2
- # make config
- Descriptions that are too long to fit in the window are shown ending in
- a "+". Scroll downward through the settings to see that the missing
- part of the description is shown at the bottom of the screen.
- Testing auto-sizing
- Open a terminal window and resize it, making it taller than the default
- 24 lines. print/ghostscript9 is a good example.
- # cd /usr/ports/print/ghostscript9
- # make config
- Work remaining to be done
- Cleanup of the code and additional comments.
- Testing.
- The trimming algorithm should break the description on whitespace to
- improve readability. fold(1) may be an easy way to do that.
