My flutter app is crashing and in the log I don't get the real lines of the crash.
It shows me the line of the crush in the .dart.lib.js file which is my file after it got converted to javascript.
Is there a way to make the logs show the real crash lines?.
My first file here is one before the last line of in the photo user_repository.dart.lib.js:27937:31

The objective of my code is to receive a specific input CSV file and modify it into an output CSV file. The input file contains headers of name and house, while the output file includes headers of first, last, and house.
When I ran this code in PyCharm, being sure to have the necessary supplementary files "before.csv" and "after.csv" in the same folder, the terminal caught no errors, and the file before.csv was successfully modified into after.csv. However, when I ran the same program in VS Code, the terminal displays
ValueError: not enough values to unpack (expected 2, got 1).
After trying to compile my program on Linux, I occasionally get error messages. Sometimes I get a lot needing me to scroll all the way to the top to see where my code broke first. Is there a short cut/faster method to scroll to the first output after I run for example a command like "make file"
I have tried "make file | less", but this chops off the first half of all the error messages, which is the part I am interested in, given that the error messages in the latter half is a result of something not being compiled correctly in the beginning of my file.
How to print only one line of my log file (that is showing the log progress) continuously in present buffer? I could not find tail -f working for me.
Basically, I have made my own command using function call in .vimrc and later on I have opened the quickfix window to show the compilation errors. Presently, i am just echoing the message "running software in background" which seems static and the user may think that the system is hanged if he runs a large design. How can I show my progress simultaneously in the current buffer from the log file which ius updated continuously?
I want empty a continuously printing log file in production,
I use below command:
echo > filename.log
I know the above command is used to empty continuously running log file if that file is getting too big.
But my query is - What happens to the old file?Does that file gets backed up or the previous data is lost forever?
How can I get the previous logs?
Previous data is basically lost forever.
You can search for backup files.There can be a file named filename.log~ for filename.log in the same directory.
It depends. If the other program has the log file permanently opened, the current log will be unlinked from its folder and your program just creates a brand new empty file. But the other program will still log to its now innaccessible file which will only be actually deleted when the program close it (or ends).
If the other program consistently uses the pattern open-write-close, you just erase previous content and new data will to that new file.
In any case old content is lost, but in first one the disk space is not reclaimed. If you want to keep it, you should google for log rotate
In VC++, how to access text continuously from console window and print it in a CListBox? Infact I have a MFC program which calls other FORTRAN exe. The output of the FORTRAN exe comes in the console window. I need to print it in a CListBox continuously. I can print it in a file and can print it at one shot. But that is not my purpose. I need continuous feed. Can any one help me out of this?
