Slides parsing fail on Windows

[Selyss]

Describe the bug Windows does not parse slide-specific text such as --- for new slides and metadata. This issue only occurs for markdown files given in args, not for the default display with no arguments.

To Reproduce Steps to reproduce the behavior:

1. Install slides on Windows through Go
2. Make a presentation file and cd to the directory
3. Execute slides example.md
4. Slides will display the characters for headings and normal markdown elements, but will not correctly build graphs, add new slides.

Expected behavior Slides will display as normal, with any metadata hidden and slide divisions when encountering a ---.

Screenshots

As you can see, slides displays as normal, but doesn't recognize new slides and other program specific elements.

Example of metadata issue

Desktop (please complete the following information):

• OS: Windows 10 Home
• Terminal: Powershell (Windows Terminal App)
• Version: Latest

Additional context The program only seems to have issue with custom symbol parsing, it can display markdown as expected. Any help appreciated!

Same issue on M1 mac with wezterm

I think this issue is related to DOS "\r\n" line breaks vs Unix "\n" and slides only seem happy with the latter.

Latest slides installed in Windows 10 using go

If I open a file with DOS line breaks "---" will not be interpreted correctly:

slides test_crlf.md

If I explicity save this file with Unix line endings it works fine

slides test_unix.md

Example files (I hope github does no line break conversion...) test_crlf.md test_unix.md

Worked for me! What did you change about the files?

The only difference is that one of the files has DOS/Windows line endings (\n\r instead of just \n as is standard in unix). I downloaded the files (as I created them when I was at work) from my comment above just to verify that github didn't do any conversion:

user$ file test_crlf.md
test_crlf.md: ASCII text, with CRLF line terminators
user$ file test_unix.md
test_unix.md: ASCII text

I can reproduce this also with slides v0.9.0 on macOS Ventura (installed from brew slides--0.9.0.arm64_ventura.bottle.tar.gz):

slides test_crlf.md

slides test_unix.md

If I convert test_crlf.md using dos2unix (which converts line endings to unix format) it will display correctly with multiple slides

I get the same behaviour with the above two files under Ubuntu 22.04.2 LTS using slides 0.9.0 installed via snap
