termsvg: error: unexpected end of JSON input #8

Closed brian6932 closed 4 months ago

brian6932 commented 4 months ago

Occurs on both play and export subcommands for me, --debug doesn't show any additional error context. Recorded with https://github.com/Watfaq/PowerSession-rs (powersession rec -c pwsh file.cast -f) and playable on powersession play file.cast. Works fine in https://github.com/marionebl/svg-term-cli.

I think the problem is with the header of the cast, PowerSession adds a custom environment property POWERSESSION_RECORDING as you can see on the test file https://github.com/Watfaq/PowerSession-rs/blob/75495685faaa40fac9932ad9dcb439f461fd0705/testdata/play.txt#L1C94-L1C116 which is not expected on my definition of environment https://github.com/MrMarble/termsvg/blob/642f0a49f3671b466e074eec68a354a6b0ecea1e/pkg/asciicast/asciicast.go#L27-L30 at least that my quick guess, I'll need to have a deeper look just in case.

I'll try to fix it soon

Doesn't seem like a POWERSESSION_RECORDING property showed up in my recording 🤔

You're right, it was way simpler than that, just had to ignore empty lines
