Would be great.

I'm curious as to why the build/ical2json.d.ts isn't part of the published npm package for ical2json?

I realize your primary focus is having this as a stand-alone CLI (which works great, btw), but in my particular TypeScript project, I'm getting error ts(7016) Could not find a declaration file. It's probably popping up on my radar in part due to my tsconfig requirements, but with your package.json being explicit on the types, I would have thought that the file should be exported as part of the published npm package.

ICS that have both an initial; VTIMEZONE section and TZID in events don't seem to be parsing.

It seems that the attachment XML is formed strangely, along the lines of:

ATTACH;VALUE=URI;FILENAME=example.jpg;FMTTYPE=image/jpeg;
 MANAGED-ID=123123123:https:
 //p47-caldav.icloud.com/long/path/to/example.jpg

So in JSON, the attachment is getting pulled into whatever field precedes it:

"SUMMARY": "Example summaryMANAGED-ID=123123123:https://p47-caldav.icloud.com/long/path/to/example.jpg

(This is occurring with an ics file downloaded from a shared apple calendar)

I was using this tool successfully for quite a while. I made a script which automatically installs it in my docker container during start-up. However, since I upgraded my docker container to the latest openHAB4.2, I get following error when running ical2json.

Any tips how I can resolve that?

Will this module work with RN? I imported it and I am getting the error:

"Unable to resolve module pathfrom/Users/user/Desktop/CGPSApp/node_modules/ical2json/index.js: Module does not exist in the module map

The module is clearly located at this path on my file system.

The iCal file I am reading is escaping comma's, for instance \, and when that goes through ical2jasn it adds another backslash \\,. This extra backslash is undesirable.

There is an TZID property in some calendars that makes the parser go haywire.

I followed the instructions and installed ical2json without errors.

When I run ical2json [filename] > c:/output.txt, the program runs without error and the output file is created, but it is empty. I am certain I have the proper path to my ics file and I know it has data in it.

Why is nothing happening?

Would there be a way to output the converted JSON to a different directory to where the source iCal file current exists?

It would be cool if this library support browser usage. I've tried mocking this up for myself by taking the convert function out of index.js and removing all of the node specific code (eg fs etc), I find that it works like a charm. While this copy-pasta solution works for my use case, it would be particularly cool if this functionality was supported right out of the box.

Thanks for making this nice library!

It should be accessed with default().

require(dir + 'build/cli.js').default(commander);

NEW_LINE should read /\r\n?/ instead of /\n\r?/. Not sure if the "?" is necessary though.

Hi there,

When I run the program to convert .ics to .json on my RPI, I get no json file, no error message, the console just starts a new line after a second or two.

If I just type in ical2json, the usage info comes up.

Any ideas what's going on?

Thanks,
Will
