OpenSUSE :: LibreOffice: Space (grey Box) Inserted Before Some Characters (?"!)
Mar 21, 2011I did not have this problem with OpenOffice in OpenSuse 11.3, it came after upgrading to 11.4. When typing some characters (these three: ?"!) a blank space (grey box) in inserted before them. If the next character is a "normal" one, the grey box disappears as soon as such next character is typed. But, if the next character is one of these three, or a space, the box stays there.
Being a local keyboard, I have to use the Shift key (? = Shift + key next to 0; " = Shift + 2; ! = Shift + 1). But, as you can see, only one of them (?) does differ from the USA keyboard, the other two ("!) are the same as for the USA keyboard. On the other hand, other characters requiring the Shift key (�$%&/()=) do not raise the grey box, so I do not think that the point be the local keyboard.

Dec 13, 2010I am developing a I2C CDROM client driver. The CDROM firmware supports TOC information read through a I2C command. It sends the TOC information in burst ( Interrupts a GPIO pin when it is ready ) and my CPU does a I2C read to read the TOC. When the CDROM firmware finishes sending the last data burst , it informs my CPU that it is done with the TOC, by a flag in the last data burst. I would like to know, which is the most efficinet way I can send these TOC information to userspace?

Programming :: Prevent Sed From Replacing With Newline
Nov 28, 2009I'm writing a script to replace some text that exists in about 50 .lex, .y, and .cc source code files, sometimes more than once in a file. Sometimes the text is in a multiline C comment, and other times it's within a multiline C string.
I use sed to grab the start and end of each line and wrap the new text in the old whitespace and/or quotes and Problem is, sed is changing the characters into a newline.
Is there a way to tell sed to not process escape sequences? I tried using several variations of
Code:
To no avail. Or could it be bash?
I would give up on the script and do it by hand, but this is something that I must do from time to time.
Here's the function which replaces the first occurrence found:
Code:
When $post is printed by echo, it shows the - but by the time the file is on disk, it becomes a newline. What should I do to ensure that it stays as the characters ?

Programming :: Replacing Text With A Http Link With Sed?
Dec 10, 2010Been at this all morning and fail on every attempt.
I have a file called sitemapindex.xml
Its contents just are names of the other sitemaps. Google gets pissy because it isn't in a http:// format.
So, I need "<loc>sitemap-c1mediawiki-............</loc>" to be replaced with "<loc>http://domain.tld/sitemap-c1mediawiki-............</loc>".
Here's the expression I've been trying:
find /path/to/site/sitemap-index-c1mediawiki* -type f | xargs sed -i 's/[<loc>sitemap]/[<loc>http://domain.tld/]/'
It fails.
I've tried with and without brackets.
Programming :: Signal From Kernel Space To User Space?
Jul 21, 2011I have the following requirement in my module. The driver gets some data from the external device. After getting 1MB of data it has to send it to the user space application. What is the best thing to implement for this in driver.? Is it ok to implement like, after getting data, the driver will send a signal to the user space application. Then the user space application sends an ioctl to read the data. Is there any alternate, that the driver directly sends the data without the user space application asks for it.?

Feb 16, 2009I'm working on my ncurses application, written in C. I get user input through a loop which uses getchar(). I was able to recognize Ctrl-n by comparing the keypress to ASCII character 16, and this seems to work fine. However, if I noticed that the ASCII character for Ctrl-j (10) is the same as the Line Feed. I tested this, and if I press enter on the keyboard I get the same ASCII value as when I press Ctrl-j.
So, what do I do if I want Ctrl-j to mean something different in my program than pressing enter?The ncurses terminal mode is set to raw, with a 100 millisecond timeout, and keypad is on (I'm already using the up and down arrow-keys).

Programming :: Displaying Unicode Characters
Feb 19, 2011I wrote a java program that writes strings to a file. The strings contain foreign language characters. When I run the program in Windows, the output file shows the foreign characters. However, when I attempt the same operation in Linux, the output file shows a white question mark in a black background instead of the foreign characters. The same Linux system could display the foreign characters if I copy the output file from Windows to Linux. I tried to create the output file using gedit that my program would then add additional strings to and chose Unicode-32 for encoding but still the same problem.
What could I do to get the program to display the foreign language characters from output text file?

View 8 Replies View RelatedProgramming :: How Renders Unicode Characters?
Oct 13, 2009I am working on an application that will convert English text into equivalent Indian language text. Since Unicode is the standard, I will be using it. In most of the western languages each code-value directly refers to the glyph index and placing the code-values side by side will give the required display. This one to one mapping is not possible in Indian languages where rendering syllables is required rather than rendering just consonants and vowels. Many of the complex characters are made up by combining several unicode values.
My question here is: How Linux renders this Unicode text correctly? More specifically, what package is used? I believe in Windows they use Uniscribe for rendering.I believe there will be an operating system library for handling the text rendering. Or do I need to write my own rendering engine? How programs like Firefox, GEdit shows unicode text? Do they also have proprietary engines for correct rendering?
Programming :: How To Add Characters And Lines To File
Jan 29, 2011For example, I have a file called "file" like this one:
type=strongsubj len=1 word=absolve pos=verb stemmed=y priorpolarity=positive
type=strongsubj len=1 word=unique pos=adj stemmed=n priorpolarity=neutral
type=strongsubj len=1 word=absolutely pos=adj stemmed=n priorpolarity=neutral
type=weaksubj len=1 word=taking pos=verb stemmed=y priorpolarity=positive
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
type=weaksubj len=1 word=usually pos=adverb stemmed=n priorpolarity=positive
type=strongsubj len=1 word=purecolor pos=anypos stemmed=n priorpolarity=negative
type=strongsubj len=1 word=accusingly pos=anypos stemmed=n priorpolarity=negative
I want to add the plural for the noun, for example if find this line:
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
will add one more line :
type=weaksubj len=1 word=friends pos=noun stemmed=n priorpolarity=positive
where we add "s" for the word friend
I did try to do like that:
<code>
cat file | while read LINE ; do
set -- ${line}
if [[ "${4#pos1=}" == "noun" ]];then
#I tried this line but it doesn't work properly:
v3==$(echo $line |sed 's/$3/$s') #I want to find the third word "word=friend" in that line and add "s" after that word
# I don't know what command to add this new line "$v3" to the file ???
done
