This is on Numbers on Mac: I generate a paragraph of text from a row where columns hold parts of text. However, as some cells are empty, I had to use conditional ISEMPTY for the formula to work:
""&B9&" "&IF(ISBLANK(C9);"";C9)&" "&IF(ISBLANK(D9);"";D9)&" "&IF(ISBLANK(E9);"";E9)&" "&IF(ISBLANK(F9);"";F9)&" "&G9&" "&H9&""
This does function, but I end up with double spaces in areas where I have one or more columns empty (so the spaces double).
Is there a way I could use an another conditional like ISEMPTY(ISEMPTY...) to get rid of those?
This is not a huge problem, but is annoying and time consuming, because I have to fix these texts afterwards (there is a lot of them). :-(
Change the parts with &" "& from IF(ISBLANK(C9);"";C9)&" "&into IF(ISBLANK(C9);"";C9&" ")&
In your formula you check if C9 is blank. Whether blank or not it's followed by a " " space. So if blank you get a space added, but no data prior to it. If the next is empty too, you get another space without data etc..
By including the &" " inside the if statement it will only add a space if C9 is not blank. Blank cell adds no data and no space.
=TRIM(CONCATENATE(B9;" ";C9;" ";D9;" ";E9;" ";F9;" ";G9;" ";H9))
Maybe you should learn about TEXTJOIN..

Sometimes I find myself editing a C source file which sees both use of tab as four spaces, and regular tab.
Is there any tool that attempts to parse the file and "normalize" this, i.e. convert all occurrences of four spaces to regular tab, or all occurrences of tab to four spaces, to keep it consistent?
I assume something like this can be done even with just a simple vim one-liner?
There's :retab and :retab! which can help, but there are caveats.
It's easier if you're using spaces for indentation, then just set 'expandtab' and execute :retab, then all your tabs will be converted to spaces at the appropriate tab stops (which default to 8.) That's easy and there are no traps in this method!
If you want to use 4 space indentation, then keep 'expandtab' enabled and set 'softtabstop' to 4. (Avoid modifying the 'tabstop' option, it should always stay at 8.)
If you want to do the inverse and convert to tabs instead, you could set 'noexpandtab' and then use :retab! (which will also look at sequences of spaces and try to convert them back to tabs.) The main problem with this approach is that it won't just consider indentation for conversion, but also sequences of spaces in the middle of lines, which can cause the operation to affect strings inside your code, which would be highly undesirable.
Perhaps a better approach for replacing spaces with tabs for indentation is to use the following substitute command:
:%s#^\s\+#\=repeat("\t", indent('.') / &tabstop).repeat(" ", indent('.') % &tabstop)#
Yeah it's a mouthful... It's matching whitespace at the beginning of the lines, then using the indent() function to find the total indentation (that function calculates indentation taking tab stops in consideration), then dividing that by the 'tabstop' to decide how many tabs and how many spaces a specific line needs.
If this command works for you, you might want to consider adding a mapping or :command for it, to keep it handy. For example:
command! -range=% Retab <line1>,<line2>s#^\s\+#\=repeat("\t", indent('.') / &tabstop).repeat(" ", indent('.') % &tabstop)
This also allows you to "Retab" a range of the file, including one you select with a visual selection.
Finally, one last alternative to :retab is that to ask Vim to "reformat" your code completely, using the = command, which will use the current 'indentexpr' or other indentation configurations such as 'cindent' to completely reindent the block. That typically respects your 'noexpandtab' and 'smarttabstop' options, so it use tabs and spaces for indentation consistently. The downside of this approach is that it will completely reformat your code, including changing indentation in places. The upside is that it typically has a semantic understanding of the language and will be able to take that in consideration when reindenting the code block.
I have been using nano to write a bash script and I am at several times indenting various lines at once with Alt + }. The problem is that the following occurs:
Several lines without text in them get white-spaces by the amount that I indent the text and they are coloured green. They don't affect the program but they make it look bad. I have been deleting them one by one but it gets frustrating over time. Is there a way to get rid of all the white-spaces at once? maybe some way to select the text (short cut for selecting text in nano is Alt + a) and have a short cut do it?
Use global search and replace with the expression ^\s+$.
Switch to search and replace mode with C-\.
Switch to regex mode with Alt-R.
Type the expression ^\s+$.
Hit Enter to replace with an empty string.
On the match, hit A for All.
I seem to be having issues with leading/trailing spaces in textareas!
If the last user has typed values into a textarea with leading/trailing spaces across multiple lines, they all disappear with exception to one space in the beginning & end.
Example:
If the textbox had the following lines: (quotes present only to help illustrate spaces)
" 3.0"
" 2.2 "
"0.3 "
it would be saved in the backend as
"<textarea id=... > 3.0/n 2.2 /n0.3 </textarea>"
My template (for this part) is fairly straightforward (entire template, not as easy...): ${label} ${textField}
When I load up the values again, I notice getTextField() is properly getting the desired string, quoted earlier... But when I look at the html page it's showing
" 3.0"
"2.2"
"0.3 "
And of course when "View Sourcing" it doesn't have the string seen in getTextField()
What I've tried:
Ensure the backend has setWhitespaceStripping(false); set
Adding the <#ftl strip_whitespace=false>
Adding the <#nl> on the same line as ${textField}
No matter what I've tried, I'm not having luck keeping the spaces after the interpolation.
Any help would be very appreciated!
Maybe you are inside a <#compress>...</#compress> (or <#compress>...</#compress>) block. Those filter the whole output on runtime and reduce whitespace regardless where it comes from. I recommend not using this directive. It makes the output somewhat smaller, but it has runtime overhead, and can corrupt output in cases like this.
FreeMarker interpolations don't remove whitespace from the inserted value, or change the value in any way. Except, if you are lexically inside an <#escape ...>....</#escape>, block, that will be automatically applied. But it's unlikely that you have an escaping expression that corrupts whitespace. But to be sure., you can check if there's any <#escape ...> in the same template file (no need to check elsewhere, as it's not a runtime directive).
strip_whitespace and #nt are only removing white-space during parsing (that's before execution), so they are unrelated.
You can also check if the whitespace is still there in the inserted value before inserting like this:
${textField?replace(" ", "[S]")?replace("\n", "[N]")?replace("\t", "[T]")}
If you find that they were already removed that probably means that they were already removed before the value was put into the data-model. So then if wasn't FreeMarker.
Along a similiar vein to this question, I'd like to store only white space in an Ax2009 table field.
...We want to be able to store " " (string containing one space or more) in a field (the field content is exported to a plain text file later on).
After an insert, the value remains " ", but if we do a Select on the table the value is replaced by "".
Any suggestions? Thanks.
You can check the workaround used in standard AX for field AddressFormatLines.Separator
An additional field NumOfSpaces is used to overcome this AX limitation, methods insert, update, and postLoad are overridden accordingly, and as a result you can store a white space and also see it in forms (although you won't see it in SQL Server).
Sorry, but trailing spaces are removed.
Live with it.
there is actually a way of storing a white space at the end of a string field. Instead of using the normal space bar enter Alt+255. That will create a space which is not removed.
I have been looking at regular expressions to try and do this, but the most I can do is find the start of a line with ^, but not replace it.
I can then find the first characters on a line to replace, but can not do it in such a way with keeping it intact.
Unfortunately I don´t have access to a tool like cut since I am on a windows machine...so is there any way to do what I want with just regexp?
Use notepad++. It offers a way to record an sequence of actions which then can be repeated for all lines in the file.
Did you try replacing the regular expression ^ with the text you want to put at the start of each line? Also you should use the multiline option (also called m in some regex dialects) if you want ^ to match the start of every line in your input rather than just the first.
string s = "test test\ntest2 test2";
s = Regex.Replace(s, "^", "foo", RegexOptions.Multiline);
Console.WriteLine(s);
Result:
footest test
footest2 test2
I used to program on the mainframe and got used to SPF panels. I was thrilled to find a Windows version of the same editor at Command Technology. Makes problems like this drop-dead simple. You can use expressions to exclude or include lines, then apply transforms on just the excluded or included lines and do so inside of column boundaries. You can even take the contents of one set of lines and overlay the contents of another set of lines entirely or within column boundaries which makes it very easy to generate mass assignments of values to variables and similar tasks. I use Notepad++ for most stuff but keep a copy of SPFSE around for special-purpose editing like this. It's not cheap but once you figure out how to use it, it pays for itself in time saved.
