Choosing line separator to prevent blank lines - phpstorm

My local development environment based on Windows and my production environment based on Linux.
I have an issue about "line separators (CR, LF, CRLF)". Every time I got blank lines in my code.
Which line separator type to should I choose for prevent the blank lines?

I am working in this exact environment as well, except my development environment is also in Linux.
The aggravating problem I have run into is editing CRLF text files in the Linux environment, whether they were Apache files, or shell scripts. Mainly, I couldn't easily edit them in Linux through vi, which is unhappy with the CR. If you never do that, then it may not be a problem for you. But if you see blank lines in your code, it might be something similar.
For HTML and PHP, Apache running in the Linux environment has never complained when serving up files or reading configuration files in CRLF.
The other side of it, was that it was hard to wrangle PHPStorm. The related post #LazyOne provided works, but PHPStorm is stubborn if you have been using CRLF as I had when I switched this setting. I found I still needed to change files by hand at times, which you can do along the bottom right of the editor window. You will see CR, LF or CRLF and you can click and change the setting for the particular file loaded in the editor:
As a side note, if you use git, you can set up a .gitattributes file in the project directory with this:
# Set the default behavior to always be linefeed for linux
* text eol=lf
Which causes git to normalize to LF as it states in the git documentation:
Set to string value "lf"
This setting forces Git to normalize line endings to LF on checkin and
prevents conversion to CRLF when the file is checked out.

VS Code - How to stop it deleting whitespaces?

I am using Microsoft's VS Code to edit css, html and ts files that are shared by my team on a VSTS Git repo. However, my VS Code keeps removing empty/whitespaces that my colleagues added when I save any change (Image below) and this screws up the whole Git Diff part, as almost every single line of code shows as a diff.
I tried to disable every single config setup but nothings works:
At the end, what was causing my problem was the extension: EditorConfig for VS Code
This plugin attempts to override user/workspace settings with settings
found in .editorconfig files. No additional or vscode-specific files
are required. As with any EditorConfig plugin, if root=true is not
specified, EditorConfig will continue to look for an .editorconfig
file outside of the project.
I believe, it was overriding the options I selected inside of VS Code (such as files.trimTrailingWhitespace: false). So, no setup change I was making was actually being applied.
It seems you have trailing whitespace enabled in User Preferences too.
I'd suggest opening your configuration file of VSCode using
CtrlShiftP or
CmdShiftP in Mac and then go to Open User Settings.
I'm sure the next line is around there somewhere, delete it or change it to false.
files.trimTrailingWhitespace": true
In my case, the JS-CSS-HTML Formatter extension from lonefy
caused the problem.

Unreadable Notebook NotJSONError('Notebook does not appear to be JSON: u\'{\\n "cells": [\\n {\\n "cell_type": "...',)

Getting this very strange error when I am trying to load my ipython notebook. Never had it before, and I cannot to my recollection, remember having done anything silly with ipython:
Unreadable Notebook: /path/to/notebooks/results.ipynb NotJSONError('Notebook does not appear to be JSON: u\'{\\n "cells": [\\n {\\n "cell_type": "...',)
which is followed by
400 GET /api/contents/results.ipynb?type=notebook&_=1440010858974 (127.0.0.1) 36.17ms referer=http://localhost:8888/notebooks/results.ipynb
Save yourself a headache. Open your .ipynb in any online JSON validator and it will tell you which lines have issues. I used this one.
In my case, I am using GitHub to save and share my ipython files with my teammate. When there is a conflict in the code, I had to delete those lines indicating the changes in the conflicting code such as:
>>>>>>>>head
=============
and It works for me.
This happened to me as well. I opened my data.ipynb file using notepad and found out it was blank.
I managed to recover my file by going into the hidden ipynb_checkpoints folder and copying data_checkpoint.ipynb out into my working directory.
In my Mac OS terminal
cd .ipynb_checkpoints
cp data-checkpoint.ipynb \..
Thankfully the codes were preserved. Hope this helps!
I just had the same issue after upgrading from IPython 0.13 (ish) to Jupyter 4.
The problem in my case were a few rogue trailing commas in the JSON, for example the comma following "outputs" in:
...
"language": "python",
"metadata": {},
"outputs": [],
},
After removing the commas, Jupyter/IPython could again read the notebook (and upgraded it to version 4). I hope this helps.
The easiest way to recover corrupted Jupyter notebook files, whether it contains text or not (size = 0KB), is to go to the project folder and display the hidden files. Once the hidden files are displayed, you will see a folder named '.ipynb_checkpoints'. Simply open this folder and take the file you want!
Visual studio code procedure
This is my procedure that usually avoids me groping in the dark.
I installed a json parser validator like this one.
Open the file and save a copy as .json file.
Open the json and look for the errors.
Save it back to the .ipynb extension.
Usually, I manage to fix the errors quickly.
Jupyter autosaves in a specific way. It means You have accidentally closed the notebook before properly saving it.
You need to look for three things -
Search for <<<<<<< and delete those lines.
Search for ====== and replace those lines with ,.
Search for >>>>>>> and delete those lines.
It will work fine after this.
this can be changed to reformat your ipynb file to readable in jupyter notebook. check your other ipynb files(open in notepad) which are working fine with your jupyter notebook, check and compare at the end of the files in notepad. there you can reformat the file which is not working.
I had this issue from accidentally saving as .txt from github and solved by deleting .txt (leaving .ipynb instead of .ipynb.txt when downloading)
Yes, the best solution for me was I saved my notebook in HTML format, then opened it in Notepad ++ , delete the long repeated lines of output which were causing my notebook to grow to 45MB, once that cleared, Saved the file back into (.ipynb) format , and was able to opened it with no JSON error.
Hope that worked for others as well!
Got this error after conflicts while pushing my code to Github. The code present on the repo was old, and my changes were stashed. Notebook wasn't opening in either Jupyter and github repo. Following above comments, I searched for the part in my code which was giving JSON error,i.e. '<<<<<<<<<<<', '=======' and '>>>>>>>>>>' characters using an online json parser. Then I opened my .ipynb notebook in notepad++ and manually replaced these characters with blank string ''. After this, the notebook opened on my local Jupyter, and I also pushed the changes to Github.
I have changed by ipynb file encoding from UTF-8-BOM to UTF-8, and then it worked.
My native language is not English, but because this problem helped me a part, I came to feedback my solution.
The following is translated with translation software:
Fundamentally, the file format is messed up due to wrong closing. When opening, the correctness of the json format will be checked first, and an error will be returned if it is found to be wrong.
The mess in my file format is not <<<<< or ====== but the lack of commas.
Either way, it's best to use a piece of software to detect errors in the json syntax, and then manually fix it yourself.
The json website detection provided by the highest praise is available, but the detection errors are not complete, and may need to be detected-modified-detected-modified.
Also use vscode to open the file, vscode will prompt the location of the json syntax error, which is also incomplete and needs to be checked and modified multiple times.
The error location provided is more difficult to find. I use nodepad++, and the lower right corner can display how many characters are selected (standard, including line breaks). Then select from the first character until the destination position.
Although it's a bit stupid, the main reason is that I didn't find the relevant positioning method.
Clear all outputs.
Then copy the notebook.
If you use Jupyter-Notebook in VS code, just save it in VS code, close the file and try to open it again by accessing the browser.
on ubuntu 20.04, I have file String.ipynb. I had same problem because I coded ơ [ echo 'hello' >> String.ipynb ]. deleting 'hello' in String.ipynb -> I could open my notebook like normal.
how did I delete? [ nano String.ipynb ] * move to last line (hello) * -> delete it.
I hope my answer help you :D
you will see this error may be because, you were getting merge conflict in .ipynb file. because of that git adds >>>>>>>> HEAD thing in .ipynb file which makes is unreadable.
To overcome this issue open .ipynb file in vim editor and then remove the incoming changes or your changes as per your use case.
vim <your-.ipynb-file-path>
To remove incoming changes remove content between these lines<<<<<<<<<< HEAD ==============. Note:- remove this line as well >>>>>>>>>>>> this line.
to remove your changes remove content between these lines ============== >>>>>>>>>>>. Note:- remove this line as well a <<<<<<<<<< HEAD
I had the same issue after git merge while using VS Code and Jupyter extension.
VS Code would not open the notebook after the merge conflicts were highlighted in the notebook JSON by git (e.g. <<<<<). One way around it was to highlight the changes and accept one by one using the file viewer in the VSCode git interface.
Alternative that worked for me was to rename the file to .json so that it would open and then search for each instance of <<<<< and accept the incoming change.

Sublime Text 2 - writing a script to process multimarkdown

There is an excellent package to preview markdown written using sublime text. I wanted to know how I might modify it, or perhaps use it as the basis for writing one that could process multi-markdown.
I'm using Linux (Ubuntu) and I'm currently calling multimarkdown in the terminal on each file.
One of the issues I think I might face is that multimarkdown refuses to parse an open file for some reason.
Any thoughts on how I might begin this or if an alternative solution exists would be very gratefully received.
There is a MultiMarkdown option in the syntax list - View > Syntax > Markdown > MultiMarkdown. Isn't that working? By the way the syntax (and almost any other) files are in packages folder of Sublime Text 2. This is the syntax file:
/Users/[username]/Library/Application Support/Sublime Text 2/Packages/Markdown/Markdown.tmLanguage
And MultiMarkdown file is in the same directory.
I'm intrigued by your statement that "multimarkdown refuses to parse an open file". Can you provide more information, or email me, or open an issue on github? MultiMarkdown doesn't check to see whether a file is open or not --- it simply reads the file and processes it. So if there's a problem, then the OS is not allowing MMD to proceed for some reason...
I don't have Sublime Text installed on Ubuntu (I generally use a command line only version of Ubuntu for testing MMD), so I can't test this situation exactly. I haven't had any other reports of difficulties parsing files (open or not). I don't have any trouble with Sublime Text 2 on Mac OS X and MMD.
As an alternative, you could try using one of the support scripts (e.g. mmd if you want MMD->HTML) and see if that has the same problem with open files.
PS> Are you using the latest build of MultiMarkdown, e.g. 4.2+?? (Though it shouldn't change anything related to open files)

CHM compiles fine, but won't open

I use a program that spits out HTML and hhp projects containing data from my databases.
I then compile that hhp with Microsoft HTML Help Compiler (hhc.exe).
It works well, but unfortunately for few projects, hhc compiles fine, but chm file is unusable.
It reports "Cannot open the file: mk:#MSITStore‎: FileName"
I have no problem with other chm files on my system. I have no problems with other chm I compile. If I remove several topics from my project produced file works again. It doesn't matter what topics I remove. Files that don't work are almost twice the size of files that work, even tho the html and project file is almost the same (very few changes), which leads me to think compression fails silently if size or structure of some file isn't right.
Does anyone have experience like this and what could be the reason?
For those that want to see example, this project will compile and work fine:
Working chm project
And this one compile but fail to open:
Chm that fails
I experienced the identical problem. The CHM was double the usual size and could not be opened. The CHM compiler did not report any error. Removing any random HTML file enabled opening the CHM. I generated many other CHMs on the same day, and all the others were OK.
I worked around the problem in the following way:
I added a very small HTML file to the project. It is a copy of one of the other files in the project, so if a user finds it in a search, it does no harm.
I entered the file name in the HHP.
I recompiled the project in the CHM compiler.
The CHM shrank to the normal size, and it opens normally.
I had exactly the same problem and can say it's all a matter of size and most likely an error in the compression module of hhc.
When I added some lines of documentation the size of the CHM-file increased from 1.6 to 3.1 MB and it could not be opened anymore.
This problem could not only be fixed by removing files but also by adding files.
So I wrote some additional documentation, added it to the project and everything was fine again.
There are a number of reasons why the MS HH compiler may crash.
(1) Invalid filenamesfile and file
The HTML Help compiler does not like some filenames e.g. spaces in a filename can still cause some minor problems with HTML Help. Best to replace spaces with underscores. Avoid "#" in file and folder names.
Try and stick with these characters _, a..z, A..Z, 0..9.
Do not use periods apart from in the normal file extension. Example: A filename such as xxx.h001.gif is identified incorrectly as a HTML file. The compiler then attempts to parse the binary file and crashes.
Do not use file or folder names containing ".chm".
(2) Avoid compiling on a network drive and try to compile on local drive.
(3) Use MJ’s Help Diagnostics to ensure that all the help viewer components are properly installed and registered.
http://helpware.net/downloads/#MJs
(4) Delete the file “hh.dat”, which you should find in this subdirectory:
\Documents and Settings\%username%\Application Data\Microsoft\HTML Help
This file stores information about all the HTML Help files on your system (Favorites, window size and position, etc.), and can cause the files to misbehave if it has somehow been corrupted.
(5) You need to debug your help system. You need to identify the file(s) that are crashing the compiler.
I normally remove sections of the web by renaming or moving folders and files, then recompile. Keep adding and removing sections until the compiler does not crash. Eventually you will find one or two files that are causing the problem. You may also need to debug these files by temporarily removing sections of the HTML file.
I see 0 byte files in the input? Maybe the compiler can't handle that?

Why does a file checked into CVS become double-spaced?

Problem
Frequently (but not every time) when using CVS to check in files like: .java, .cs, .xml, etc, every line of the file is gets a carriage return.
Example:
File before check-in by a team member:
// Begin file
class Foo
{
public Foo()
{
// Do step 1
// Do step 2
}
}
// End file
File when checked out by a team member:
// Begin file
class Foo
{
public Foo()
{
// Do step 1
// Do step 2
}
}
// End file
Development Environment
NetBeans 6.8 and now 6.9 (the problem occurred when using 6.8 as well).
Visual Studio 2008 and 2010.
Repository: CVS; checkins and checkouts done from Cygwin bash shell.
Operating system: Widows XP Professional.
What I Have Tried
I tried changing the value: build.compiler.emacs=true within NetBeans under Tools->Options, thinking this might be causing some kind of Unix/Windows translation problem when checking in? This made no difference.
Am I missing something about what happens to a file when it gets checked into CVS in a Windows/IDE/Cygwin stack that can cause this problem?
Something is converting DOS line breaks (CR LF) to pairs of Unix line breaks (just LF). I would personally bet on its being CVS. You might want to try using TortoiseCVS instead of Cygwin CVS.
A Windwos-native CVS client will convert MS-DOS line endings in a text file (\r\n) to Unix-style line endings when submitting the file to the server, so that in the repository, the files are maintained in a 'canonical' form with \n representing a line ending. When Windows native client will also convert the line ending when bringing a file down from the server.
However, I believe that the default Cygwin CVS client acts like a Unix client and assumes that no line ending conversion is required. So if you use that client to check in a file with MS-DOS-style endings (\r\n), you'll get this kind of confusion.
It looks like the people who are using the Cygwin client are using tools that care converting the files to MS-DOS style line endings (or something is).
A potential fix is to uninstall the Cygwin CVS client and install the WinCVS client on your Windows/Cygwin boxes so the Windows native client will be used even when a Cygwin shell is active:
http://www.dehora.net/journal/2003/07/a_fix_for_cygwin_and_cvs_linefeeds.html
Another possibility to to configure your Cygwin mounts under a specific mode (but I'm not really familiar enough with Cygwin to know how well this works or if it might introduce otehr problems - it's been a long time since I've tried using Cygwin):
http://www.gigascale.org/softdevel/faq/23.html
Another possibility that I just ran into - if the file was saved in Unicode format but stored in CVS as ASCII/Text, extra line terminators will be added.
