Deleting the first word in a string
hi! i'm learning regex and with this code i would like to
1) print a string (from "Hi my name is SandraPandra. do not print this")
2) remove the first word and print the new, shorter string
3) remove the first word in the new, shorter string and print the newer and shorter string
4) continue this until it hits a non-character (e.g period, colon, quotation marks etc)
does anyone here know how i should change my code in order to achieve this?
here's my code:
class Testar {
public static void main(String[] args) {
String partDesc = "Hi my name is SandraPandra. do not print this.";
do {
System.out.println(partDesc);
partDesc = partDesc.replaceFirst("^(\\w+)\\s+","");}
while (partDesc.equals("\\w") == true);
if (partDesc.equals("\\w") == false){ //this is where something goes wrong
System.out.println("found a full stop!");}
} the outcome now is:
Hi my name is SandraPandra. do not print this.
found a full stop!
Thank you in advance!
I answered this question in your previous thread. (Sorry, I didn't realize "I'm going to bed now" was a code for "I won't be reading this thread any more". ^_^ )
I would also like to point out that it's bad form to write conditions like if ( booleanExpression == true ) It's gratuitously verbose, and it creates the potential for subtle bugs. Suppose the boolean expression is a non-final boolean variable, and you accidentally leave out one of the equals signs: if ( booleanVariable = true ) An assignment statement evaluates to the value that was assigned, so this "condition" will always be true.

Even more about deleting the first word in a string
hi, i have this code that removes the first word in a string, returns the shorter string, removes the first word from the shorter string aso... what i would like it to do is to stop when it hits a non-character, but i can't get it to do that. does anyone know why \b won't work?
import java.io.*;
class Testar {
public static void main(String[] args) {
String partDesc = "Hi my name is SandraPandra.";
while (partDesc.equals("\b") == false) { //this is where something goes wrong
System.out.println(partDesc);
partDesc = partDesc.replaceFirst("^(\\w+)\\s+","");
} thanx in advance!while (partDesc.equals("\b") == false) That compares partDesc to a string consisting of one backspace character. I suspect you're trying to use the regex word-boundary anchor, but that's a dead end. If you want to stop beheading the string when the regex stops matching, you can write the code exactly that way: class Testar {
public static void main(String[] args) {
String partDesc = "Hi my name is SandraPandra.";
while ( partDesc.matches("^(\\w+)\\s+.*") ) {
partDesc = partDesc.replaceFirst("^(\\w+)\\s+","");
System.out.println(partDesc);
} If performance is a concern, you can use a pre-compiled Pattern object for greater efficiency. Thanks to Matcher's lookingAt() method, you can use the same regex for the test and the replacement: class Testar {
public static void main(String[] args) {
String partDesc = "Hi my name is SandraPandra.";
Pattern p = Pattern p = Pattern.compile("^(\\w+)\\s+");
Matcher m = p.matcher(partDesc);
while ( m.lookingAt() ) {
partDesc = m.replaceFirst("");
System.out.println(partDesc);
m.reset(partDesc);
} The ^ anchor isn't really necessary in this version, since lookingAt() implicitly anchors the match to the beginning of the string, but you might as well leave it in. -
Delete the first word in a string?
Hi, i have a code in which i can extract the first three words in a string. after it's found the three first words, i would like it to remove the first one, what could i add?
this is what the code looks like:
import java.util.regex.*;
class Test187D {
public static void main(String[] args) {
String word1;
String word2;
String word3;
String partDesc = "Hi my name is SandraPandra";
Pattern pattern = Pattern.compile("^(\\w+)\\s+(\\w+)\\s+(\\w+)");
Matcher matcher = pattern.matcher(partDesc);
//Find the first word of the part desc
if (matcher.find()) {
word1 = matcher.group(1);
word2 = matcher.group(2);
word3 = matcher.group(3);
System.out.println (word1 + " " + word2 + " " + word3);
} Thank you in advanceTake the length of the first word, plus one for the length of the space, that's how many characters to remove. Take the substring of the original string from the end of the removed part to the end of the whole string. Look up the String methods length(), and substring().

Script to get the first word on each page
Is there a script that would make a list of the first word of each page (or, preferably, create a text box on each page and place the next page's word in that)? My document's all in one story with one text frame on each page, although there are several other frames (header, page number) applied through master pages.
You wrote: I changed the numbers to "8.0425in", "4.5681in", "8.1275in", "5.4319in" and it mostly worked - it placed the box at exactly 5 inches (X) and at 8.085 inches (Y) instead of 4.5681 inches. Any idea why?
No. I cannot reproduce the error you describe. I assume you've checked your numbers very closely in the script--I don't normally indicate measurements as strings.
you wrote: Something wasn't working with the styling - it kept freezing the program -
What do you mean by "freezing the program"? Is there a specific error message?
The paragraph style is named "firstword" and is all lowercase letters?
firstword paragraph style is NOT in a paragraph style group, right?
Is the first word on any page too long when formatted with the paragraph style "firstword" to fit in the text frame? -

ID only imports the first word of a 233 page word file (a novel)
Folks!
I've tried the old FIle-Place make a text box and shift+enter..... and I ONLY get the first word of a 60,000 document. Why?
I need help ASAP!There are a lot of possibilities causing the problem, probably it is caused by some formatting done in Word.
What text styles are used in Word? Do they have some break options? Repair them in Word.
Are text boxes/frames used in Word? Remove them in Word.
Is in Word some kind of break inserted (section, page, column, …)? Remove them in Word.
But also important:
When you import the Word file, do you select the import options during import? Do it!
In InDesign is a character style selected before importing, before choosing the text tool? Don't.
Because we don't know the source of the Word file it is hard to tell you what it is. A huge problem are Word files which have been converted from PDF or other programs.
I would try to get rid from any Word imported formatting. Imported styles from Word I would never use in InDesign, I import them often, but I have my own styles predefined in InDesign. After importing I delete step by step the Word formatting. I know, I could map the Word Styles to existing InDesign styles, but in my experience some unexpected things are happening when the Word file comes from someone else than me, because a lot of people have only limitted knowledge when it comes to Word styles and document structure. -
How can I make iTunes sort on the first word by default, even though that word is "The" or "A"?
How can I make iTunes sort on the first word by default, even though that word is "The" or "A"?
I myself think that (for instance) "A tribe called Quest" should be sorted under "A", not "T".
Now I can edit the sort options manually per track and/or per selection, but I would really like to just kill this "iTunes-knows-how-you-should-sort"-feature in iTunes.
Anyone any suggestion on how to do that?
ThanksHere is a modified version of one of Doug's Scripts. My modification was to add Sort Name to the list of tags that could be changed. I tried it on a single track and it worked. I recommend backing up your library first. Select the tracks you want to change (or all tracks) and run the script from the Applescript Editor. If it works as intended, save it so you can apply it to newly imported tracks. And, yes, I know this isn't the exact answer to your question, you want to change a preference setting in iTunes (if there is such a setting).
Original script can be forund at http://dougscripts.com/itunes/scripts/ss.php?sp=thistagthattag
Modified script is below. Start up Applescript Editor, paste it into a new window. Start up iTunes and select the tracks to modify. Click Run in the Applescript Editor. Follow the instructions.

You are writing that in the perspective of having read about it here already. Repeated often enough that you encountered it somewhere in the posts.
Users are flooding in here and don't know any of this. Of course we have to repeat everything endlessly.
Because I like to give precise, understandable and workable answers to repeated questions, and Apple doesn't allow sticky posts here, I created a separate forum which users can consult to look up real answers, and contribute for themselves if they have something valuable to add:

There is a section purely devoted to Pages 5. Add whatever answers you feel will lighten the problems of Apple's 'upgrades'.

* Where have they acknowledged anything?
** They have barely anything listed, compared to the massive list of deleted features, and nothing but an extraordinarily long time frame considering they created the problems here and now. Apple has not said they will do anything at all about fixing the real issues, the biggest of which is that the new iWork apps break virtually all the work of existing users. -
Replace all up to the first word character
I have a String with a value of *1. Artist - Title*. What I am trying to do is remove everything up to the first word character so the new String will be Artist - Title. This is all I have been able to come up with:track.replaceAll ("\\d ^\w","").split (" - ");{code} Also, I used {code:java}track.replaceFirst ("\\d","").replaceFirst ("\\W","").replaceFirst ("\\s",""){code}but that isn't practical at all (even though it works).
I tried to find examples on a few regular expression sites, but maybe I'm not searching with the right keywords. My code won't even compile. Anyone have a hint?public class RegexExample3 {
public static void main(String[] args) {
String input = "1. Artist - Title";
String output = input.replaceFirst("^[^A-Za-z]*", "");
System.out.format("'%s' ==> '%s'%n", input, output);
}For your requirements, you need to be cleared about "word character", since \w means [A-Za-z0-9] -

Here's how to find the right word in a string
I needed to find the rightmost word in a string. I didn't find a simple formula in these forums, but I now have one, so I wanted to share it. Hope you find it useful.
Assuming that the string is in cell A1, the following will return the rightmost word in the string:
RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1," ","*",LEN(A1)-LEN(SUBSTITUTE(A1," ","")))))I found the problem. Whatever character was being used in the substitution was parsed out by the forum parser. I replaced it with "œ" (option q on my keyboard).
=RIGHT(A1,LEN(A1)-FIND("œ",SUBSTITUTE(A1," ","œ",LEN(A1)-LEN(SUBSTITUTE(A1," ","")))))
Still needs an error check for a single-word "sentence" and to remove the trailing period but it does seem to work. Pretty slick.

When I type the first word's letters are always mixed up
using an Apple extended USB keyboard that came with my mac pro (2x 3ghz Dual Core Xeon processor, 18gb 667MHz RAM)
It's like the Mac cant react fast enough to catch the first one or two letters and it just inserts them into the middle of the first word.
like "Hello" would be "ellHo" and "OK" is "KO"
the rest of the sentence is fine. or the rest of the paragraph, it seems to inly happen when I first select a text field or when I have been idle for mor ethan 30 seconds. this happens in all apps. Mail, Firefox, Textedit etc.
i have not yet unplugged the rest of my USB peripherals but that is my next step.
Ihave a ADF scanner, multifuncion printer, logitech wireless mouse, usb plantronics headset, iMo 7" USB monitor. running os 10.7.2
just upgraded and everything was fine in 10.6.x.
anyone else experience this?
thanks
SteveI have similar problems with an Apple Wireless Keyboard (Bluetooth) and a MacBook Pro since installing Lion I am running 10.7.2 also. See https://discussions.apple.com/message/16701228#16701228 for more detail. I think it's a bug in Lion.

The system doesn’t recognize or capitalize the word (I) or the first word of every sentence. Another really annoying thing about the integrated mail on your Mac computers is the fact that the system learns the word as you type it more and more instead of highlighting it as incorrectly is this is a word that’s being misspelled. Can Apple fix this bug to make it user friendly as if you were using Office or a Word Document?
You hit the target CT.
It’s only fair that if Apple is going to integrate Mail into Mac PCs, it would be nice if the system does it for you like Office or perhaps Outlook. I just don’t to use Outlook although I have it installed and ready to use, but instead use Mail which comes with Mac OS already.
I hope to make some sense here. -
Last night I downloaded the latest Word update. Today the first Word document crashed and I lost 45 minutes of work in spite of having saved the document numerous times. Why is Word crashing the day after a safety update? I have Office 2008 for Mac
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
Open Console in Applications>Utilities, check the system log for the date/time of the last problem & next startup for clues.
