  • Virtual terminal with at least 16bit color?

    - by trusktr
    It's 2013 and there should be terminals with more than 256 colors by now (you'd think). Are there any terminals with more than 8bit colors (usually from 8 bit we jump to 16bit) to use with linux? Ideally, I'd like to have a linux terminal with 32bit colors for the foreground and background of each character. So, the functionality would be the same, with escape sequences, but just more of them (or something like that?).

  • Set CSV import default to UTF-8 in Calc

    - by picca
    Every time I open a CSV (comma separated values) document in OpenOffice.org Calc I get a dialog with CSV preferences. The current default character set is "Eastern Europe (ISO-8859-2)". I would like "UTF-8" to be selected by default instead.

  • where is backspace key of Mac?

    - by George2
    I am using a MacBook Pro running Mac OS X 10.5. I am new to this development environment, and previously worked on Windows. I am wondering what is the backspace key of Mac (i.e. which is used to delete the character previous to current cursor position in text editor)? Windows keyboard has a dedicated backspace key, but I did not find such a key on my MacBook Pro keyboard. Thanks in advance.

  • How do I parse file paths separated by a space in a string?

    - by user1130637
    Background: I am working in Automator on a wrapper to a command line utility. I need a way to separate an arbitrary number of file paths delimited by a single space from a single string, so that I may remove all but the first file path to pass to the program. Example input string: /Users/bobby/diddy dum/ding.mp4 /Users/jimmy/gone mia/come back jimmy.mp3 ... Desired output: /Users/bobby/diddy dum/ding.mp4 Part of the problem is the inflexibility on the Automator end of things. I'm using an Automator action which returns unescaped POSIX filepaths delimited by a space (or comma). This is unfortunate because: 1. I cannot ensure file/folder names will not contain either a space or comma, and 2. the only inadmissible character in Mac OS X filenames (as far as I can tell) is :. There are options which allow me to enclose the file paths in double or single quotes, or angle brackets. The program itself accepts the argument of the aforementioned input string, so there must be a way of separating the paths. I just do not have a keen enough eye to see how to do it with sed or awk. At first I thought I'll just use sed to replace every [space]/ with [newline]/ and then trim all but the first line, but that leaves the loophole open for folders whose names end with a space. If I use the comma delimiter, the same happens, just for a comma instead. If I encapsulate in double or single quotation marks, I am opening another can of worms for filenames with those characters. The image/link is the relevant part of my Automator workflow. -- UPDATE -- I was able to achieve what I wanted in a rather roundabout way. It's hardly elegant but here is working generalized code: path="/Users/bobby/diddy dum/ding.mp4 /Users/jimmy/gone mia/come back jimmy.mp3" # using colon because it's an inadmissible Mac OS X # filename character, perfect for separating # also, unlike [space], multiple colons do not collapse IFS=: # replace all spaces with colons colpath=$(echo "$path" | sed 's/ /:/g') # place words from colon-ized file path into array # e.g. three spaces -> three colons -> two empty words j=1 for word in $colpath do filearray[$j]="$word" j=$j+1 done # reconstruct file path word by word # after each addition, check file existence # if non-existent, re-add lost [space] and continue until found name="" for seg in "${filearray[@]}" do name="$name$seg" if [[ -f "$name" ]] then echo "$name" break fi name="$name " done All this trouble because the default IFS doesn't count "emptiness" between the spaces as words, but rather collapses them all.

  • Why do Chinese filenames displays as boxes in Windows 7?

    - by Roddy
    I'm running Windows 7 Professional (UK), and trying to get filenames containing Chinese characters to display correctly in Explorer. I can create Chinese filenames in explorer by pasting text from a webpage or using the Chinese IME to rename files, but the characters just display as boxes (Unicode 'missing character' glyph). The Chinese fonts are installed on the system, and web pages display OK in the browser. In particular, I can see the correct Chinese filenames by pointing chrome at file://C:\, for example.

  • Overcoming maximum file path length restrictions in Windows

    - by Christopher Edwards
    One of our customers habitually use very long path names (several nested folders, with long names) and we routinely encounter "user education issues" in order to shorten the path to less than 260 characters. Is there a technical solution available, can we flick some sort of switch in Windows 7 and Windows 2008 R2 to say "yeah just ignore these historical problems, and make +260 character path name work". P.S. I have read and been totally unedified by Naming Files, Paths, and Namespaces

  • How do I add ancient Greek accents in Ubuntu?

    - by Matthew
    I am taking a course in ancient Greek, and there are various accents that go above the vowels. I want to be able to type these on Ubuntu. For example, if I hit ';', then 'a' (while in the modern Greek keyboard layout), I get this character: ?. However, I can't figure out how to add the other accents (` and ^, for example).

  • How do I turn off accent combining in Windows 7?

    - by shinjin
    I have English Windows 7 Professional with Hungarian keyboard language installed. The English keyboard layout works as expected, but for the Hungarian layout some kind of "accent combining" is activated. The effect of this ^+o becomes ô, ^+a becomes â, etc. This is not helpful at all, since the accented characters of Hungarian are already mapped to keys, but it's really annoying because I have to type a non-combining character to actually get ^. Is there any way to turn this "feature" off?

  • Notepad++: is there a way to force it to keep the autoindented-whitespace type?

    - by daVe
    I wonder if we can force notepad++ to respect the previous whitespace character when it autoindents a new line: list[CR][LF] ····item1[CR][LF] ····item2[CR][LF] --->| (notepadd++ screenshot recreation showing hidden characters, because I don't have enough reputation to post images, sorry xP) If I am indenting with tabs I want a tab when notepad++ does an autoindent. But if I am indenting with spaces, I do want spaces.

  • Pressing tab to indent a list moves to the next table cell

    - by Ryan Ternier
    I have a list (e.g., a bulleted list) in Microsoft Word. This list is inside a table cell. When I press Tab to increase the indent, rather than increasing the indent, it moves the cursor to the next cell. When I try Ctrl+Tab, it just inserts a tab character without changing the indentation of the bullet (paragraph). How can I turn this off, so it does not go to the next cell but rather just indents the list?
