#39871 - 2003-05-02 07:06 PM ReadLine Function
Stryder Stryder Lurker Registered: 2003-04-28 Posts: 2 Loc: Kansas	I need to be able to have a script read a text file and capture the value of each line in the file. I know how to read a line with readline or you can even manually add another readline ($x = readline + readline) and get the first two lines of the text file. Is there a way to have the script determine how many readline's it needs to perform to get the entire contents of the file? Below is an example of what I am working with and I have the script manually reading the first two lines of the file. If Exist ("\\pathtofile\$month$day.txt") $msgtext = $msgtext + 'Birthdays for today are:' + chr(10) IF Open(3, "\\pathtofile\$month$day.txt") = 0 $x = ReadLine(3) + chr(10) + ReadLIne(3) Close (3) EndIf $msgtext = $msgtext + chr(10) + $x + chr(10) + chr(10) EndIf I then use a messagebox to display the value of $msgtext. Can someone help? Thanks

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11165 Loc: Boston, MA, USA	It would be much more convenient to put this type of info into an .INI file code: ;birthdays.ini [Birthdays] 01/01/1990=John Doe, Jane Doe ;or [01/01/1990] John Doe=Marketing Jane Doe=Sales _________________________ There are two types of vessels, submarines and targets.

They may be perfect for what you are trying to do and could save you a lot of effort. NMM

NTDOC NTDOC Administrator Registered: 2000-07-28 Posts: 11629 Loc: CA	Hello Brian, Here is an example of doing what you're looking to do. You need to supply the real path to the BIRTHDAYS.INI file and you need to fill it out to include ALL MONTHS and ALL DAYS as well as ALL USERS with their Birthday on that month and day. It is possible to do this other ways, but this should suffice or at least give you a little more insight on how it can be done. Hope this helps, if you have questions please don't hesitate to ask. The Piranha members around here will be happy to help. DisplayBirthdays.kix $Y = SUBSTR(@DATE, LEN(@DATE) - 9, 4) $M = SUBSTR(@DATE, LEN(@DATE) - 4, 2) $D = SUBSTR(@DATE, LEN(@DATE) - 1, 2) $MyFile=("C:\TEMP\birthdays.ini") $Birthdays=ReadProfileString ($MyFile, $M, $D) $AlertBD=MessageBox("Today is "+@DATE+@CRLF+"Happy Birthday to "+$Birthdays, "Happy Birthday", 64) birthdays.ini [01] 01=John Doe 02=Bill Smith 03=Brian Wilson 04=George Garthy 05=Jane Doe [02] 01=John Miller, Jack Black 02=Karen Gleason [03] 01=Wendy Feiten 02=Brad Jones [04] 01=Greg Engle 02=Tim Vinter 03=Beth Angel [05] 01=Carl Celt 02=Kevin Empire, Andy Burke 03=Helen Birch 04=Celine Welsh, Bart Sordel

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	Here is one of the Piranhas playing KiXGolf with it : break on $f = @scriptdir + '\Birthdays.ini' $BDs = readprofilestring($f, right('0'+@monthno,2), right('0'+@mdayno,2) ) if $BDs $_ = messagebox("Todays Birthdays are:" + @crlf + $BDs, "Happy Birthday", 64) endif {partially 'borrowed' from Richard} _________________________

NTDOC NTDOC Administrator Registered: 2000-07-28 Posts: 11629 Loc: CA	See Brian, What did I tell you about those Piranha. All these good ideas. Let me recommend though, that regardless of who's idea/code you use. Make sure you liberally comment the code so that in the future you'll know what and how it does it. Code that is left alone for long periods of time can be difficult to decipher unless you work with it daily. I know some Admins write stuff and don't look at it or touch it for Months at a time, then when they go back they have trouble knowing what it does because they don't script or code daily. Unlike some of the Piranha here who play with it daily and can get away with this KiX Golf coding style (though if done in production, the next Admin to come along won't be happy with them ) Commenting code is a Best Practice but few do it.

NTDOC NTDOC Administrator Registered: 2000-07-28 Posts: 11629 Loc: CA	I hope not. I for one do not share that attitude. You've handed nothing on a Silver Platter at work, but rather you've done your job, which in my opinion should include allowing others to easily assist you or take over the job in case you are injured, promoted, or laid off. Why would you want someone else to suffer? Just don't see the reason why one human being would want another to suffer when they had done nothing to you.

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11165 Loc: Boston, MA, USA	Actually, I do need "code on a silver platter" for myself, as I do tend to forget why I wrote a certain routine in a specific way. Especially if you suddenly have to reexamine code you've written two or three years ago. _________________________ There are two types of vessels, submarines and targets.

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4402 Loc: New Jersey	Boy, this touched a nerve! I've got to agree with Doc on this one. I've posted code heer in the past and had several (good) suggestions about making it shorter. I've also seen several examples posted here that I had to scratch my head on... Remember which forum we're in!! Here, simple code is usually better. It's OK to follow it with a comment that "blah-blah" is a shorter way to write it, but will new users really get it (today)? I'm in the midst of extending the comments in my code and then writing documentation on the coding as well as the operation, because staff members at two other main sites have been assigned to be my "scripting backup" - in case I get hit by a bus. Anyway, just remember which forum you guys are in and describe how your cool code works when you post it.. maybe even say that your code replaces such-and-such lines of code so the new guy can actually learn about KixGolf concepts.

Kdyer Kdyer KiX Supporter Registered: 2001-01-03 Posts: 6241 Loc: Tigard, OR	Can see both sides of the coin here.. Documentation is good in the event you are no longer able to perform script functions.. However, there is a good point, that if you "squeeze" the script down, the time it takes to parse it through will be less. This, then begs the question at what expense? Something so cryptic that nobody understands? Or, is just something infinitessimal? So, for example, you take the script from 40ms to 20ms, is that a good trade-off? These numbers are still less than a second. Thanks, Kent _________________________ Utilize these resources: UDFs (Full List) KiXtart FAQ & How to's

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	these last replies have been pretty informative... seems that the amount of coders who really know what they are doing when they put letters together is pretty small in the kixtart-expert field. glenn on the other hand is little bit different as if he really has backup-coders. for those indeed it's good to have some docs. anyway, if you have say UDF that does work, why every newbie should need to understand it after 30 years? the main point is to produce working code which is reliable and fast. not saying that on KORG you can't post well documented code, but saying that for your own usage it's best practise to comment, I have to disagree. it's totally different if ppl forget what their yesterday's code does and are unable to read kixtart code which is mix of english and math. then, sure, for your own best, you should do that... or start eating b-vitamin to get your memory better. _________________________ ! download KiXnet

New Mexico Mark New Mexico Mark Hey THIS is FUN Registered: 2002-01-03 Posts: 223 Loc: Columbia, SC	The previous comments raise a question about how KiXtart tokenizes and runs scripts. IIRC, the script is initially parsed and tokenized to memory, then run from there. Granted, a ton of comments might slow down the this phase slightly, but should make no difference in the script execution speed once complete. Personally I'd rather wait a few milliseconds more to load well-documented code than to spend much more time unraveling poorly-documented code (even my own) before making a change. NMM

Kdyer Kdyer KiX Supporter Registered: 2001-01-03 Posts: 6241 Loc: Tigard, OR	Wouldn't this be a good opportunity to use something like KIXREF and spool this info to a separate file? The only downfall to that would be is that if you had any updates, you would have to re-run it. Kent _________________________ Utilize these resources: UDFs (Full List) KiXtart FAQ & How to's
