cgi-cal - A Web-Based Calendar Application
- cgi-cal is a simple online calendar program that uses the cal
application for the hard work of creating the actual calendar layout.
- Like a lot of households, keeping track of upcoming events and appointments
has always been somewhat of a problem for us because of our various paper,
PDA, and whiteboard calendars. I enjoy hacking on providing various intranet
projects, and had been fiddling with the idea of
an online calendar for a quite a while but was daunted by the prospect of
creating a table representing a month in calendar format. Then one evening while
mowing the lawn it occurred to me that I could use
Perl to parse the output from my
intranet server's command line cal application. So I set to work
and by 3:30am the next morning cgi-cal was born.
- The mowing finally got finished a couple days later...
- Key Features
- Month layout is displayed (thanks to cal)
- The current day is displayed in red.
- Each days events are displayed in it's text box.
- The Month and Year can be selected from the drop-down menu at the top of the page.
- Users can jump backward or forward one month using the links at the top of the calendar.
- To save entries for the currently selected month click Change Entries at the bottom of the page.
- By default this will only display options for years 2000 - 2020
since that's all I need, if you need more or are reading this page
in the year 2019 the fix should be fairly straight forward.
- This is far from immune to multi-instance database trashing,
some kind of file locking should be implemented if more than one user
could be clicking the Change Entry button at the same time.
- If you're looking for a more professional calendar system here are a few links that may be useful:
- Downloading and Installing
- cgi-cal should work on your
favorite Un*x system with a
CGI-Enabled web server,
the CGI Perl module,
and some version of either cal or gcal.
- It should also work on Win32 systems if you use
and Active State's ActivePerl.
- The database is really just a semicolon delimited text file, to set it up
you'll simply need to create a blank text file and make sure the security is
set correctly so your web server can write to it. File locations are all specified
in the first few lines of the script.
- Enjoy, just remember where it came from. :-)
- cgi-cal - version 2.1
- cgi-cal-v1 - version 1.1 - older version before daily text-boxes.
- Legal Mumbo-Jumbo
- Feel free to download and use this software as you wish.
This software has been tested, but I am not responsible for
anything that occurs to your computer.
- Use at your own risk, yada, yada, yada.
