Right now we're using the synchronous endpoints.

Given an empty directory out, and in/index.mmd containing:

# Test

Here is some text referencing footnote one[^1].

[^1]: This is a footnote.

Then running npx mpx build --input in --output out does not handle the footnote correctly. You end up with html that renders like this in a browser:

Here is some text referencing footnote one[^1].
[^1]: This is a footnote.

(where the text [^1] is just plain text, not a link)

However, npx mpx convert in/index.mmd out/index.html converts the footnote correctly, so that you end up with html that renders like this:

Here is some text referencing footnote one[1].
This is a footnote. ↩︎

(where the [1] is a link to the footnote, and the ↩︎ is a link back to the relevant point in the document)

>mpx --version
0.4.0

I run this:

>mpx convert --verbose "xxx.png" "xxx.mmd"

And get this:

Source: xxx.png
Destination: xxx.mmd
Options: { pdfMethod: 'latex', verbose: true }
Convert with snip api xxx.png xxx.mmd mmd

Hi:

I just tried calling the API using the mpx path/to/input.pdf path/to/output.docx method and received the following warning (5 times).

I have attached the (single-page) PDF file in question.

Page 250.pdf

The Markdown and MS Word documents I requested are downloaded successfully, but what do you recommend?

When I try to convert pdf files to Markdown using mpx convert file.pdf file.md, it seems like it always uses the non-standard Mathpix Markdown format, even when I don't use the mmd file extension. I was wondering if there is a way to export to standard Markdown, similar to the functionality found in Snap Web?

Hi there,

I am trying to install spectra following the instructions in Github, which I understand is only to run npm install -g @mathpix/spectra. This is the error message I obtain, once and again:

I would very much appreciate some clue to solve this problem, perhaps only mine because I have not too much experience on this kind of things.

Many thanks for your time and effort!!!

I've been playing around with mpx ("@mathpix/mpx-cli": "^0.4.0") to build a github pages site from some markdown files with inline and block equations, and noticed some strange behaviour.

Given src/index.mmd, and an empty docs directory, invoking mpx with npx build --input src --output docs results in:

bash-5.1# npx mpx build --input src --output docs
Converting src to docs
Wrote 0 files in 0.24 seconds

If I rename src to source and repeat, it works fine:

bash-5.1# npx mpx build --input source --output docs
Converting source to docs
Wrote 1 file in 0.57 seconds

mpx convert input-file.pdf output-file.tex

When I changed the file extension to .tex, it could be opened normally.

Hi,

I am trying to convert an image in my user root folder.

The command I am using is as follows:

mpx convert image.jpg image.mmd

It succeeds in converting, but it says this:

Convert with snip api image.jpg image.mmd mmd                                                                           
Could not write to destination path: image.mmd

Finally, I lose a snip from my plan and can't see it.

I tried it in another folder that has 777 permissions and the same thing happens.

What can I do?

Thanks!
