Experimenting with pandoc module using just Lua

[-- Attachment #1: Type: text/plain, Size: 727 bytes --]

Dear All,

Is there a way to experiment with the objects pandoc module using Lua
without having to write a filter/writer and go through the pandoc CLI? I
would really like to just experiment with generating documents and getting
familiar with the Lua API using just a Lua interpreter.

Regards,

Amine

Fwd: Experimenting with pandoc module using just Lua

[A A]

[-- Attachment #1: Type: text/plain, Size: 1393 bytes --]

I guess a better way to phrase my question is the following:

*Is there a way to generate a document from scratch and programmatically
using Lua and without using Haskell?*

There is mention here <https://pandoc.org/using-the-pandoc-api.html#builder>
of a pandoc Builder class but I don’t see its Lua equivalent here
<https://pandoc.org/lua-filters.html#module-pandoc>.

Hi Bastien,

I'm afraid that doesn't really show me how I can build a document from
scratch similar to what is done in Haskell using a `Builder`.

I really would like to avoid learning Haskell and stick to the Lua API. But
I'm getting the impression that use of the Lua API requires understanding
of how the underlying Haskell objects interact.

Regards,

Amine

Re: Experimenting with pandoc module using just Lua

[Bastien DUMONT]

I don't think that you can do this directly from a Lua interpreter. This is how I would build a document programmatically:

```build.lua
function Pandoc(_)
  return pandoc.Pandoc(
    pandoc.Para({
        pandoc.Str('Hello'),
        pandoc.Space(),
        pandoc.Emph(pandoc.Str('World')),
        pandoc.Str('!')
    })
  )
end
```

pandoc -L build.lua <<< '' outputs `<p>Hello <em>World</em>!</p>`.

Hi Bastien,

Thanks, that's a bit more like what I'm looking for.

However, when I try to compile in Powershell using `pandoc -L build.lua` I
get no output and the command prompt just kind of hangs there until I press
Ctrl+C.

Pretty sure I'm doing something wrong but I'm not sure what....

Regards,

Amine

Re: Experimenting with pandoc module using just Lua

[Bastien DUMONT]

You need to supply an empty input to pandoc. In Powershell, you can type `echo '' | pandoc -L build.lua`.

AW: Experimenting with pandoc module using just Lua

[denis.maier-NSENcxR/0n0]

IDK if the use case is common enough to warant a new command line parameter...

But, what about a new option like this?

`pandoc -L build.lua --no-input`

The example `echo '' | pandoc` works with Powershell, but not with cmd. There you'll get the result:
<p>ÔÇÖÔÇÖ</p>

Don't know about bash or other shells.

Denis

Re: Experimenting with pandoc module using just Lua

[BPJ]

[-- Attachment #1: Type: text/plain, Size: 9739 bytes --]

In bash or zsh I would typically use

``````
pandoc -L build.lua
^D
``````

Wouldn't the same work in Windows? (tho with Ctrl-Z instead of Ctrl-D I
believe!)
