Warning: last line of file ends without newline..... However it does? - warnings

I'm working on a tricky warning and, I just can't seem to get to the bottom of it. Here's what's going on:
I created a header file to define the register addresses for one of my sensor devices. My program works great however, upon compiling the project, I get the warning "device\device_reg.h(44): warning: #1-D: last line of file ends without a newline"
However, when I go to the file, it does appear to end in a new line. I remember that some text editors sometimes don't appropriately handle enter the newline. So, I deleted the newline, hit the return at the end of the new line, and recompiled. The warning persisted. I repeated this process with notepad++ and the original notepad in windows. Same results...
I am currently compiling c++ code in Keil 5.1.0.0 with an Arm compiler version 5.03.0.76
Any help would be greatly appreciated.
Thank you,
Beau

I had a similar problem with an included file. It turned out that the last line was indented. So when I hit the enter key the next line was indented leaving spaces on the new line. I hit back space to return the last row to the 0 position and the warning went away.

So, it wasn't the solution that I wanted. However, I resolved the issue. I combined the register map definitions with the class header file. I still don't know why I was getting this problem earlier and if anyone has any insights that would be great. However, as for now, this problem is solved.
Thank you.

PhpStorm isn't doing code completion with large file

I've just installed this library. PhpStorm does its usual code completion, except for the \XeroAPI\XeroPHP\Api\AccountingApi class. The \XeroAPI\XeroPHP\Api\IdentityApi class in the same folder works just fine.
The file is quite big - 2,560KB. If I delete roughly half of the 65,000 lines from the class (and it works whether it's the first half or the second half) then I get my code completion back. In fact, I can delete just the last 3,000 or so lines (getting the file down to 2,499KB) and it works.
I've also tried a quick regex find/replace to remove all the #throws PHPDoc comments. This got the file down to 2,491KB and hey presto, code completion works fine.
If I had to make a guess I'd say it's not doing code completion with source files over 2.5MB or something, but I can't find any setting for this.
Any way to get code completion going with this file short of deleting stuff from it (which will be restored next time I do a Composer update anyway)?
Based on your info (especially the mentioned file size and the fact that it starts to work after reducing it) you have hit a limit of max file size that IDE is willing to parse and index.
Solution: configure idea.max.intellisense.filesize option using Help | Edit Custom Properties command. By default it has a value of 2500 (size in KB). Set it to 3000 or so (to cover your file size) and restart IDE (it reads and applies settings from idea.properties file on start only).
idea.max.intellisense.filesize=3000
P.S. Do not put that value too big as it may cause other performance issues.

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.

Close a single tab in Chrome using Batch command

I'm relatively new to batch commands and have been learning steadily. My problem is like this:
I've understood how to kill processes using batch commands using many different methods. However, I've been unable to figure out how to close a single tab in, preferably, chrome.
Any thoughts would be greatly appreciated!
Thanks!
So, I suppose I should state my exact problem.
I'm using notepad++ as my LaTeX compiler and sending the final pdf to chrome. The reason: I usually have ~20 tabs open related to the project I'm working on and it just makes my work much easier to split my screen between notepad++ and chrome.
My current batch file compiles the LaTeX code and sends the compiled document to chrome as a new tab. For obvious reasons, i don't want to close a tab each time I compile, so I thought that closing the current tab at the same time during compiling would solve my problem. But, I just can't find a way to get my batch file to only close the tab with my compiled pdf.
Thanks in advance!
check all running chrome instances/tabs with :
wmic process where "caption='chrome.exe'" get
and see processes properties.Probably the best indicator that you can rely on in this case is CreationDate (other properties are basically the same for all chrome instances) - it always comes in format YYYYMMDDHHmmss.ms and is easy for string comparison.But you'll have to know the time when it was started.

In monodevelop how can I clear out the Task list?

My task list pad is filled with old //Todo comment tasks that have been parsed out of the code. Unfortunately the files they refer to have long since gone and the tasks are hanging around like zombies. Deleting each task simply throws an error that the file is missing. How can I manually force a complete cleanout of the tasks list so it can reparse? I had a quick look at the source code for this part of MD but I didn't see anything obvious.
I'd suggest you file a bug.
However, for a quick workaround, try deleting the code completion database caches. On Mac you can find them in ~/Library/Caches/MonoDevelop-3.0/DerivedData, and on Windows they're in AppData\Local\MonoDevelop-3.0\Cache\DerivedData.

Method or Data Member Not found for every control or event

Got a weird problem. I was debugging some code for a form and everything was working as intended for the most part when suddenly I began to get a "Method or Data Member Not Found" for every event of my form. It's like my form suddenly does not recognize any of my controls or events. I have all of my methods properly closed and did not rename any controls.
Any ideas on what would be the root of "Method or Data Member Not Found" for every single control with an event?
Thanks
Importing into a fresh database as talbright suggested gave me more descriptive error messages.
A fresh import, compact&repair, and renaming of appropriate control fixed the problem from occuring. As Remou suggested, regular maintenance can help prevent these sorts of problems.
edit for future readers: This problem occurred while using a shared front end file. So don't do that if possible.
I've found that any MISSING: reference can make the simplest of code fail.
Check in the visual basic window
Menu Tools -> References
look down the checked refences to see if any are MISSING
I just fixed the same error by renaming text and combo boxes something not so close to a concatenated Table & Field string. Actually just prepended those names with "tbx" and "cbx".
