I am using a text file as an XML template for a project I am working on in Xcode with Swift 3. Depending on the type of request I am putting together from the template, sometimes certain lines are not needed. Is there a way in Swift to delete a single line from a text file? My searches are coming up empty.
A little more background: At runtime the contents of the file are copied into an NSString. I do not need to modify the text file itself, just the string that is being instantiated by the file. I have tried doing string.replacingOccurrences(of:string with "") but that is leaving gaps in the file. This actually works, I was just hoping for a more elegant solution.
Change your search and replace criteria to include the white space.
Another alternative would be to use NSRegularExpresssion and stringByReplacingMatchesInString to also remove all surrounding white space.

I am able to open large files and it works great, however I do not get line numbers even though that option is on by default. It does for xml files, but a text file with .xml extension does not.
Any ideas on how to get the line numbers or maybe the software is not meant to do that?
The Large File Editor does not display line numbers.
It does have the concept of lines, so you can move to a specific line using menu Edit->Go to... (Ctrl+G).
Depending on your PCs specification, you may be able to open larger files without invoking the Large File Editor, please see:

I'm creating a pdf with the scribble/acmart language. How can I add page numbers to my document?
Make a LaTeX file with the line \settopmatter{printfolios=true}
If the file is named texstyle.tex, invoke Scribble with the command:
scribble ++style texstyle.tex --pdf FILE.scrbl
The rendered FILE.pdf should have line numbers.
(If you already had a ++style file, just add the \settopmatter line to that.)
The solution Ben gave is one way. But you can actually do this without modifying your texstyle.tex file.
If you add the following lines to your document, the appropriate topmatter will be added to your pdf file:
#para[#:style 'pretitle]{
#elem[#:style "settopmatter"]{
printfolios=true}}
You can see it doing this by running:
> scribble --latex myfile.scrbl
If you do this, you will notice the following line in your pdf file:
\settopmatter{printfolios=true}\titleAndVersionAndAuthors{Hello}{6.9.0.4}{\SNumberOfAuthors{1}\SAuthor{World}}
(Where Hello and World is the name and author of your paper, and the \title... macro runs \maketitle.)
This works because the 'pretitle style (when given to a paragraph), pulls its entire body above the title.
And whenever a string is given as the style for an element, it maps to the a latex command.
That is, this scribble code:
#elem[#:style "mycommand"]{Thebody}
Maps to:
\mycommand{Thebody}
The result of composing these two forms together is to drag this to the top of the file.
And because you've done this in scribble rather than latex, you can use Racket's semantics to add page numbers. For example, if you use your own #lang, you can now have the language decide whether or not you want pages.
I'm using Perl WWW::Mechanize package in order to fetch and process data from some websites. Usually my way of action is as follows:
Fetch a webpage
$mech->get("$url");
Save the webpage contents in a variable (BTW, I'm not sure if it's the right way to save this amount of text inside a scalar which, as far as I know, supposed to be used for a single value)
my $list = $mech->content();
Use a subroutine that I've created to write the contents of the variable to a text file. (The writetoFile subroutine includes few more features, like path and existing file validations..)
writeToFile("$filename.tmp","$path",$list);
Processing the text in a file created in the previous step by creating an additional file and save the processed content there (Then deleting the initial temporary file).
What I wonder about, is whether it is possible to perform the processing before storing the text in a file, directly inside the $list variable? The whole process is working as expected but I don't really like the logic behind it and it seems a bit inefficient as well, since I have to rewrite the same file multiple times.
EDIT:
Just to give a bit more information about what I'm actually after when I process the variable contents. So the data I fetch from the website in this case is actually a list of items separated by a blank line and the first line is irrelevant to me. So what I'm doing while processing this data is 2 things:
Remove the empty (CRLF) lines
Remove the first line if it includes a particular text.
Ideally I want to save the processed list (no blank spaces and first line removed) in a file without creating any additional files on the way. In order to save the file I would like to use the writeToFile sub (I wrote) since it also performs validation on whether such file already exists (If a file will be saved before final processing - the writeToFile will always rewrite the existing file).
Hope it makes sense.
You're looking for split. The pattern depends: use (?<=\n) split at a new line character and keep it. If that doesn't matter, use \R to include all sort of line breaks.
foreach my $line (split qr/\R/, $mech->content) {
…
}
Now the obligatory HTML-parsing-with-regex admonishment: if you get HTML source with Mechanize, parsing it line-by-line does not make much sense. You probably want to process the HTML-stripped text version of the document instead, or pass the HTML source to a parser such as Web::Query to declaratively get at the pieces you need.
i've downloaded the DejaVu open source font and want to use it ad a WebFont, but even when converting it, i get a large file, and because the website i'll use will be only in few languages (arabic, french, amazigh) then, i dont need some characters.
so is there a way to browse the font file and delete the unnecessary range of unicode characters that i'll not need?
Using FontForge, you may open Element->Font Info->Unicode Ranges. You will see all available ranges and you can select a whole Unicode range with a single click. Then, you can tune your selection and delete using Encoding->Detach & Remove Glyphs.
Also, you can use Edit->Select->Select by Script.
The easiest method I found is to use pyftsubset tool from FontTools. Here's an example:
$ pyftsubset NotoSans-Regular.ttf \
--unicodes=U+0400-045F,U+0490-0491,U+04B0-04B1,U+2116 \
--output-file=NotoSans-Regular.cyrillic.woff2 \
--flavor=woff2
Note: woff2 output requires Brotli.
I wrote a simple script around it which automates the whole process including generation of a CSS file after splitting the font file. You may find it here: https://github.com/johncf/ttf2web
I want to automate some writer tasks. I need to create a .odt writer
document with oo:doc using methods such as create paragraph and append
paragraph. The problem is that append paragraph and create paragraph does not
allow text to start at middle of page or at a certain column, ie
Name Surname Address
When I unzip the "master" document I want to to create, when I inspect the content.xml file i see the xml equivalent is
" <text:p text:style-name="Text_20_body"><text:s text:c="115"/><text:span text:style-name="T1"><text:s/>Hallo how are you today</text:span></text:p><text:p text:style-name="P1"><text:s text:c="116"/>I hope you are well also</text:p><text:p text:style-name="P1""
How do I set the text:c and text:s element(s) from within oo::doc
Question2:
How do i set the formatting of a paragraph
to only extend from ie column 20 to column 80
thanks
Those elements are for runs of non-breaking spaces. the text:c attribute says how many spaces there are.
That doesn't strike me as a solution to what you want, which is to change the margins and position of a paragraph, yes?
Do you have a document that you want to use as a template, where the text will be inserted? Or ar you trying to create the entire page from scratch?
I think you want to use OpenOffice.org to create a Writer document that has the structure you want, then look at the XML to see what the markup is that accomplishes that. Look at paragraph-level styles or even frames if that is what is used. You might be able to create insertion points for your generated content by then adding magic-text phrases that you can scan for.
Then figure out how to get that done with the perl module.
