You can change how you save individual files in Visual Studio 2017 for Mac Go to Tools Add Custom Tool. In the dialog box that appears scroll the left menu down to the Text Editor section and select General. In the first option, Line ending conversion, change Leave line endings as isto Always convert line endings. Jun 18, 2020 The Quick Fix for “End of line character is invalid” If you’re here to quickly fix a single file that you’re having problems with, you’re in luck. At the bottom right of the screen in VS Code, click the little button that says LF or CRLF. After changing it to your preference, Voila, the file you’re editing now has the correct line. A better approach would be to detect the most common line ending in a. File, and to use that line ending style, instead of only using the. Last line's ending. Even better would be to apply the new line-ending style to only new. Lines in a file (using the most common line ending for the new lines), and never rewriting line endings of existing lines. Just give the name of your file to dos2unix as an argument, and it will convert the file's line endings to UNIX format: dos2unix foo.txt # Replace foo.txt with the name of your file There are other options in the rare case that you don't want to just modify your existing file; run man dos2unix for details.
Convert Line Endings of Mac and Windows to Unix in Rails and Test with RSpec
Line endings or newline is a special character(s) to define the end of a line. The line endings special character(s) vary across the operating systems. Let’s take an example, we are developing a Rails feedback application which will be used by a wide range of users. The users might submit the feedback from different operating systems which has different kind of line end character(s). The content should have formatted for standard line endings before storing into backend.
Mostly two special characters used to define the line endings in most of the operating systems.
Line Feed (LF) - n
Carriage Return (CR) - r
The usage of these two special characters for Unix, Mac and Windows are
| OS | Characters | Name |
| Unix | n | LF |
| Mac | r | CR |
| Windows | rn | CRLF |
Note:- r is the newline character up to Mac OS version 9, after that Mac uses Unix line endings.
It is a developer’s job to convert all kinds of line endings to Unix line ending format to maintain the standard. We can achieve this by a regex pattern replace. The regex pattern should convert r(Mac) or rn(Windows) to n(Unix).
We can see the conversion of line endings to Unix from Mac and Windows using irb (Interactive Ruby) shell.
1. Mac
2. Windows
RSpec Tests
After the implementation of line endings conversion, it should covered with test cases for the best practices of development. Here is the bunch of Rspec code to test both Mac and Windows line endings conversion.
The line endings conversion plays a crucial role in standardising the content. It is recommended to convert line endings to Unix style when providing web service features.

The paper on a typewriter rides horizontally on a carriage. The Carriage Return or CR was a non-printable control character that would reset the typewriter to the beginning of the line of text.
However, a Carriage Return moves the carriage back but doesn't advance the paper by one line. The carriage moves on the X axes...
And Line Feed or LF is the non-printable control character that turns the Platen (the main rubber cylinder) by one line.
Hence, Carriage Return and Line Feed. Two actions, and for years, two control characters.
Every operating system seems to encode an EOL (end of line) differently. Operating systems in the late 70s all used CR LF together literally because they were interfacing with typewriters/printers on the daily.
Windows uses CRLF because DOS used CRLF because CP/M used CRLF because history.
How To Convert Line Endings In Visual Studio For Mac 2017
Mac OS used CR for years until OS X switched to LF.
Unix used just a single LF over CRLF and has since the beginning, likely because systems like Multics started using just LF around 1965. Saving a single byte EVERY LINE was a huge deal for both storage and transmission.
Fast-forward to 2018 and it's maybe time for Windows to also switch to just using LF as the EOL character for Text Files.
Why? For starters, Microsoft finally updated Notepad to handle text files that use LF.
BUT
Would such a change be possible? Likely not, it would break the world. Here's NewLine on .NET Core.
Regardless, if you regularly use Windows and WSL (Linux on Windows) and Linux together, you'll want to be conscious and aware of CRLF and LF.
I ran into an interesting situation recently. First, let's review what Git does
You can configure .gitattributes to tell Git how to to treat files, either individually or by extension.
When

is set, git will automatically convert files quietly so that they are checked out in an OS-specific way. If you're on Linux and checkout, you'll get LF, if you're on Windows you'll get CRLF.
Viola on Twitter offers an important clarification:
'gitattributes controls line ending behaviour for a repo, git config (especially with --global) is a per user setting.'

99% of the time system and the options available works great.
Except when you are sharing file systems between Linux and Windows. I use Windows 10 and Ubuntu (via WSL) and keep stuff in /mnt/c/github.
However, if I pull from Windows 10 I get CRLF and if I pull from Linux I can LF so then my shell scripts MAY OR MAY NOT WORK while in Ubuntu.
I've chosen to create a .gitattributes file that set both shell scripts and PowerShell scripts to LF. This way those scripts can be used and shared and RUN between systems.
You've got lots of choices. Again 99% of the time autocrlf is the right thing.
From the GitHub docs:
You'll notice that files are matched--*.c, *.sln, *.png--, separated by a space, then given a setting--text, text eol=crlf, binary. We'll go over some possible settings below.
text=auto- Git will handle the files in whatever way it thinks is best. This is a good default option.
text eol=crlf- Git will always convert line endings to
CRLFon checkout. You should use this for files that must keepCRLFendings, even on OSX or Linux.
- Git will always convert line endings to
text eol=lf- Git will always convert line endings to
LFon checkout. You should use this for files that must keep LF endings, even on Windows.
- Git will always convert line endings to
binary- Git will understand that the files specified are not text, and it should not try to change them. The
binarysetting is also an alias for-text -diff.
- Git will understand that the files specified are not text, and it should not try to change them. The
Again, the defaults are probably correct. BUT - if you're doing weird stuff, sharing files or file systems across operating systems then you should be aware.
Edward Thomson, a co-maintainer of libgit2, has this to say and points us to his blog post on Line Endings.
I would say this more strongly. Because `core.autocrlf` is configured in a scope that's per-user, but affects the way the whole repository works, `.gitattributes` should _always_ be used.
If you're having trouble, it's probably line endings. Edward's recommendation is that ALL projects check in a .gitattributes.
The key to dealing with line endings is to make sure your configuration is committed to the repository, using .gitattributes. For most people, this is as simple as creating a file named .gitattributes at the root of your repository that contains one line:* text=auto
Hope this helps!
I hope Microsoft bought Github so they can fix this CRLF vs LF issue.
