Printing lua tables

Printing lua tables

[denis.maier-NSENcxR/0n0]

[-- Attachment #1: Type: text/plain, Size: 595 bytes --]

Hi,
When playing around with filters I use pprint.lua or inspect.lua to visualize lua tables. Would it make sense to include some sort of <print the contents of this table> to pandoc ?
Best,
Denis

I think I've mentioned this before... but I'd be happy to contribute (in a
suitable form) the somewhat-pandoc-aware utility that I use for this.

Given this input:

*% *cat doc.md

---

a: 1

b: |

  2 3 4

---


# Header


This is a sentence (and a paragraph).


* This is a list item

* And another


| Right | Left | Default | Center |

|------:|:-----|---------|:------:|

|   12  |  12  |    12   |    12  |

|  123  |  123 |   123   |   123  |

|    1  |    1 |     1   |     1  |


: Demonstration of pipe table syntax.

and this filter:

*% *cat rep.lua

local utils = require 'utils'


-- do it this way to avoid reporting MetaBlocks twice

function Pandoc(doc)

    utils.temp('meta', doc.meta)

    utils.temp('blocks', doc.blocks)

end

this command:

pandoc doc.md -L rep.lua >/dev/null 2>doc.txt

generates the attached.

Re: Printing lua tables

[William Lupton]

[-- Attachment #1.1: Type: text/plain, Size: 3577 bytes --]

All,

I've split this out into two functions (each currently in its own [attached
as .lua.txt] file):

   - dump(value, maxlen=70) that returns a possibly multi-line string
   representation of a value
   - output(...) that's a utility function that outputs space-separated
   arguments, each passed to dump() and with a terminating newline if needed

Here's an updated example filter (it uses output() and doesn't call dump()
directly):

local output = require 'output'
function Pandoc(doc)
    output('meta', doc.meta)
    output('blocks', doc.blocks)
end

Please feel free to do whatever you like with these functions.

In my environment I have an additional layer in which I derive a log-level
from PANDOC_STATE.{trace,verbosity} and use this in a set of logging
functions like this one (*please let me know if you'd like me to supply
these too*):

function error(...)
    if logLevel >= -1 then
        output('(E)', ...)
    end
end

Cheers,
William

All,

Here's a shameless plug to let everyone know that these pandoc-aware
logging functions are now available at
https://github.com/wlupton/pandoc-lua-logging and will soon be referenced
from https://pandoc.org/lua-filters.html#debugging-lua-filters.

Things have moved on a bit since I sent the message below. Please do take a
