A light-weight command line interface to split large files and merge them back.

Hello World 👋

Hi, I'm Mariana. I use GitHub to talk to myself and keep an order in my code.

Generally, I love:

• Multi-threading
• GPU programming
• Image Processing
• Plots and insights on plots
• Microcontroller boards, and buttons, and sensors, and all that.
• Redux + React
• Golang, C++ and the CUDA framework. I could talk about these all day (Oh, and CMake).
• Linux

But basically, any good solution.

cylf's Issues

Does not merge

Hello,

I like what I have read about cylf since it is almost exactly what I need but have a problem.

I was testing on my Windows with your existing cylf binary and was able to split a test file with no problems.

cylf -a cut -n 1 -f BitComet_1.95_setup.exe

file: D:\Torrent\cylf\downloads/BitComet_1.95_setup.exe
[PROMPT] File will be cut into: 24 pieces with size: 1048576 bytes

[SUCCESS] Piece 24/24: D:\Torrent\cylf\downloads/95_setup/95_setup_23.cylf
[SUCCESS] File cut successfully

The problem seems to be when I tried to merge it back together.

cylf -a merge -i 95_setup -f test.exe
[PROMPT] File: ./95_setup/test-merged.exe
[SUCCESS] Files found: 24
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x38 pc=0xb9a557]

goroutine 1 [running]:
main.merge({0xc00000a108?, 0xc000020090?}, {0xc00000a0e8, 0x8})
        /home/mariana/Documents/github-mariana/cylf/src/cylf.go:89 +0x377
main.main()
        /home/mariana/Documents/github-mariana/cylf/src/cylf.go:126 +0x265

for which it did not merge the file from the "95_setup" directory.

Also, I noticed that when splitting the file with the "-n" switch that if would not allow for any size less than 1 MB as I would also like to experiment with creating chunks down in the KB range as well, if possible.

Any thoughts on these issues/questions?
Thanks
