I'm a newbie to Linux. I want to create my own ASCII character logo to be displayed on the Linux terminal(it is for pleasure and also to learn). I searched through the internet and found there are tools available for that work. For example,Figlet,Neofetch,Screenfetch etc. But I want to know if there is any method to create a such a logo except hard-coding the logo. If anyone know please help.
You're much more likely to get an answer if you explain clearly.
By 'ASCII character logo' you could mean that you want to create your own character (as in letter/number/symbol) and use it in the terminal just like you'd be able to display the 'L' letter. For that you'd need to create your own font, add your character in and set the terminal to use that font. There are plenty of tools online that can help you create a font.
If you mean you simply want to display some ascii art on the terminal, you can use something like this: http://patorjk.com/software/taag/#p=display&f=Graffiti&t=Type%20Something%20. You can save the text to a file on your linux computer, and print it back out again using the cat command.
An example is below:
cat ascii_logo.txt
You do also list things like figet, which will automatically generate the ASCII art for you from some text - I'm not sure why these don't fulfill your needs?

Normally programmers use a ready to use library like ncurses.
You can also do it by hand if you really have to much time. To get for example the border lines of a dialog window you have to take a look at the current code page your terminal is emulating, for example: Code Page 850. As you can see, you will find single and double line boarders and also crossings and so on. Now you have to move your cursor to a given position, print that char from the code page and ... lots of work. Moving cursors itself can also be done by simple chars from your emulated terminal by using escape codes.
As said: Instead of doing it all by hand, simply use a lib like ncurses.
You can use some python libraries like pyTermTk or textual, there is wide selection of
libraries to choose from.
I know that there is lots of info for colouring the output of certain commands, but I want to have a specific colour for everything I write into the Mac terminal.
It would allow me to have a special colour for everything I input - not the output, just the code I personally input - making it easy to scan the code to where the last command was. I want to find a way to do it without having to write a colour alias for every single command - A way that by default will implement a unique colour for everything I write in the terminal.
Thanks for your help.
I have now sorted this...
Open your ~/.bash_profile in whatever editor you prefer.
Add the following code:
export PS1="\e[0;32m[\u#\h \W]\$ \e[m"
and save.
You will now see that your command prompt is coloured green, and it's super easy to find yourself in the terminal :)
Hope that's helpful for anyone trying to fix the same problem!
P.S> These instructions cover more than just the colour in the terminal... They also control what it shown in your command prompt. I'm afraid that it will need someone way more advanced at coding than me to decipher which bit refers to what... Sorry!
I've export my bookmarks from FF in to a html file but it's too huge and complicated, so I need to remove some firefox lines from it to make it more lighter and plain.
I can replace basic things in the Notepad++ but I guess I do need some operators for this and I have no idea how to make it work right.
For example here is the line from the file containing a link to Logodesignlove :
Logo Design Love
I need to remove all those tags I don't care about, like LAST_MODIFIED="1256428672", ICON_URI="bunch of digits" ICON="bunch of characters" etc.
And of course I need to remove all those tags in every link in the list.
So I was thinking like use something like "Find all tags LAST_MODIFIED="anynumbers" and replace it with nothing/remove it" - it doesn't work though.
Examle how it should like:
Logo Design Love
So far I removed LAST_MODIFIED and ADD_DATE lines thanks to Aleksandr. So LAST_MODIFIED="\d+" worked just fine. But ICON and ICON_URI are still there. I've tried ICON="\w+" - but it doesn't work. I guess it has something to do with the slashes.
Why look for what you don't want when it's easier to keep hold of what you do want and drop the junk?
(<A HREF=".*?").*?(>.*?>)
with
$1$2
Code edited to suit Notepad++ now I know it doesn't need the special chars escaped. Thanks Aleksandr.
Read up on using regular expressions (the java regex tutorials are a good start http://docs.oracle.com/javase/tutorial/essential/regex/), and try one of the online regex tools to help write and test it, such as this one http://gskinner.com/RegExr/
Eg, remove "LAST_MODIF..." with the regex LAST_MODIFIED="\d+"
Otherwise, you may want an XML-specific tool, or even write an XSL. However, I don't know much about that.
I want to extract text contents from GUI apps,here are 2 examples::
example 1:
Suppose I opened firefox, and input url : www.google.com
how can I extract the string "www.google.com" from firefox using my own app ?
example 2:
open calculator(using gcalctool),then input 1+1
How can I extract the string "1+1" of calculator from my own program?
in brief ,what I want is to find out whether there is a way to extract the text contents from any widget of an GUI application
Thanks
I don't think there's a generic way to do this, at least not a very elegant one.
Some inelegant ideas:
You might be able to modify the X window system or even some toolkit framework to extract what is being displayed in specific window elements as text.
You could take a screenshot and use an OCR library to convert the pixels back into text for the interesting areas.
You could recompile the apps of interest to add some kind of mechanism for asking them questions.
You could use something like xtest to inject events highlighting the region of interest and copying it to the clipboard.
I believe firefox and gcalctool are for examples only and you just want to know in general how to pass output of one application to other application.
There are many ways to do that on Linux, like:
piping
application1 | application2
btw here is the Firefox command line manual if you want to start firefox on Ubuntu with a URL. eg:
firefox "$url"
where $url is a variable whose value can be www.mozilla.org
That sounds difficult. Supposing you're running X11, you can very easily grab a window picture ( see "man xwd"); however there is no easy way to get to the text unless it's selected and therefore copied to the clipboard.
Alternatively, if you only want to capture user input, this is quite easy to do, too, by activation the X11 record extension: put this in your /etc/X11/xorg.conf:
Section "Module"
Load "record"
#Load other modules you need ...
EndSection
though it may prove difficult to use too, see example code for Xorg/X11 record extension fails
Sometimes I work with a file that contains source code, columns, plain text, sometimes all 3. It looks great on the screen. However, when I send it to a printer, it comes out a mess: columns/tables are misalignment, code looks like a spaghetti, etc.
I use Vim (7.2). How do I reformat the file to please the printer?
Perhaps I should shorten the length of a line?
How do you send it to printer? Try :hardcopy command.
You can also lookup printing-related options printfont, printdevice, printoptions, etc.
See also printoptions and others on vimdoc.sourceforge.net
It's not a pure-Vim solution, but I've had good experiences with GNU a2ps for converting (relatively) poorly formatted text documents (a couple Project Gutenberg titles, to be specific) to a nice, printable pdf/postscript file.
If you aren't worried about having to have a one-step process with no intermediary between Vim and the printer, here is a fairly flexible strategy.
If you have a dark background in Vim with light foreground but would like to print black-on-white since white-on-black is great for terminals but not so great for printed media, try colorscheme shine. (Another nice colorscheme for this is Hemisu, which is superior to Shine for printing diffs.)
Use :TOhtml to convert the document to HTML.
Save the file and open it in your browser.
Open print preview from your browser and set up the window appropriately.
For example, I just printed a nearly 200 column file brought in from Vim this way, and it worked out fine (both in the sense of "well" and in the sense of "small print" :) because I was able to use Firefox's print preview to set the file to print in landscape mode.

I agree there is a problem. yim has 'formatoptions' to 'wrap' lines together the way you want and break lines at appropriate places ('linebreak', 'breakat') which would give you an elementary wysiwyg word-processing capability, except that it only works on the display and has no effect when sent off to print.
