Pandoc Document Conversion Email Tutorial

On top of yesterday’s Pandoc Document Conversion Command Line Tutorial Document Conversion progress we’ve been wondering how to offer assistance in our public realm up at the rjmprogramming.com.au domain. Today, as you can see with our YouTube video presentation, we’ve got it so that …

… offers that last Email and Download link to help out a user …

  • who is not interested in installing any PHP local Apache web servers … but …
  • is using macOS or Mac OS X (and so can access textutil) … and/or …
  • has installed (the Open Source) pandoc (with pdflatex perhaps)

… and who establishes an inhouse Downloads folder listener script such as our convert_this_please.ksh Korn Shell one that we execute (in the background) via …


ksh convert_this_please.ksh &

… and looks out for the Email Document(s) button functionality of …

… with the file naming conventions (after email attachment download(s)) …

Downloads Path
${HOME}/Downloads
Downloads Input Name
convert_this_please_[OutputExt]_[OriginalInput_Name].[OriginalInput_Ext]
Downloads Output Name
convertthisplease[OutputExt][OriginalInputName].[OutputExt]

… effectively bypassing any local PHP web server for direct command line processing via downloaded email attachments.

The changed macos_textutil_convert.php live run link calls on a changed client_browsing.htm and gets you to a “surfing the web” incarnation.

As intimated, below we show this functionality in action …

Pandoc Document Conversion Command Line Tutorial

Yesterday’s Pandoc Document Conversion Multiple Tutorial intimated what direction we might be taking up today, when it said …

… still assuming the files selected are off your local web server’s Document Root (but more on that later down the track, maybe).

Considering this challenge, the “outside your usual thought pattern box”, perhaps, would be to remember that PHP’s modes of use can be…

  • surfing the web (with a web browser) …
  • curl (at command line) …
  • command line

… and it is introducing that “command line” PHP mode of use above that can strip out the relevance of $_SERVER[‘DOCUMENT_ROOT’] (per se) as a concept, so that in this mode of use, we effectively start from scratch asking the user for four pieces of information as per …

Description Default
Input path dirname(__FILE__)
Input filespec
Output path dirname(__FILE__)
Output file extension

This web application (now also command line app, given you have a local web server featuring PHP such as MAMP) suits this “command line” mode of use ahead of its “surfing the net” way for a couple of reasons (to us) …

  • we think “command line” gets conversions done faster …
  • as per yesterday’s challenge, given file permission allowances, you can read and write to places that aren’t within the $_SERVER[‘DOCUMENT_ROOT’] directory hierarchy
  • as a PHP programmer, these modes of use can be neatly separated … the “command line” mode of use code is totally self contained …

For …

  • longer than we can remember we’ve really enjoyed batch processing …
  • as long as we can remember we’ve really enjoyed the File API that came with HTML5 …
  • ([as long as we can remember] – 2 months) we’ve really enjoyed the File API input type=file multiple attribute …

… and, adding to the recent Pandoc Document Conversion Primer Tutorial all get a guernsey today … yay !!!

It was the normal natural way to think, before GUI style operating systems, and the normal being command line, to achieve the most use of those precious (and more resource limited) computing resources to organize programs towards achieving procedural programmatical work for a “batch of data” if possible. Of course, batch processing is still performing a lot of the hard computing tasks being performed on servers around the world today, but you’d be hard pressed to hear about much of it in the public realm, which is so admiring of individual use and personalization. “Big data” thoughts though, bring thinking back to grouping those individual data sets together into a useful group analysis raison d’être (no doubt needing batch processing again).

To “sort of” meet the “batch processing” world with a web browser web application we have the File API input type=file multiple attribute to work with, and with our Document Conversion work (still focussed on local web server usage) the HTML …


<input type=file accept=".pdf,.doc,.docx,.htm,.html,.txt" multiple></input>

… along with the knowledge that even multiple files are selected from a single file path hidden from a File API coder but “localhost derivable” in that similar approach we used with the Haiku Creation web application (alas, only helping out macOS users (in this programmatical “in the background” approach), though Windows Pandoc’ers can fill the paths in within two new textboxes) …

… still assuming the files selected are off your local web server’s Document Root (but more on that later down the track, maybe).

How do we reflect this multiple file (batch’y) processing talent with a way to display this in a web browser web application? We choose to hive off each single input/output Document Conversion data set into an individual popup window instance, and display there that output data as converted, if possible.

The changed macos_textutil_convert.php live run link calls on a changed client_browsing.htm to reflect on this “batch’y” style multiple file capable Pandoc or textutil Document Conversion functionality.

Yesterday’s MacOS Document Conversion Primer Tutorial left off with a link, as per …

… read here

… and it was here and with help from other links below that we took a big interest in a great Open Source product (great at Document Conversions) called pandoc …

… the reason for the interest in MikTeX being a wish to include pdflatex into the PATH as distinct from our preferred approach to add an additional switch …


--pdf-engine=[pathTo]pdflatex

… to try to match the success of pandoc at the Terminal application command line but not with PHP exec usage. This issue occurred with our macOS system after our two Homebrew install commands (in Terminal session) …


$ brew install pandoc
$ brew cask install basictex

… and, visually, you can see some of with today’s tutorial picture.

This Pandoc integration allows a way in for our web application to be operable for Windows or Linux servers where you have installed Pandoc, as well as pdflatex for Word to PDF conversions. Clearly, to open the door to more platforms is a step we welcome, and may spare us a Panadol?!

The changed macos_textutil_convert.php reflects this Pandoc integration.

A good thing about a “version control” or “source control” system is that you can …

  • “pick up” from any version …
  • “clone” to another name …
  • “branch off” immediately into a new version …

… to effectively “clone” the suitable progress point from a previous project as the start to a new project.

So on top of yesterday’s “way back when” MacOS Text to Audio Primer Tutorial early stage “progression point” of our “Voiceover Ideas” back to “macOS say” (just works with macOS and MacOS X underlying operating system under PHP “online presence”) interfacing, we “start off” a new “Document Conversion” web application (you guessed it) initially only working with macOS and MacOS X underlying operating system under PHP “online presence”.

Like for below, Document Conversion via Mac OS X’s command line textutil command used by PHP via exec to make macos_textutil_convert.php … cloned via macos_textutil_convert.php … (which is useful as a download to a Mac OS X laptop using MAMP) which, today, does not yet have a very interesting live run because the web server of domain rjmprogramming.com.au is a CentOS Linux server … Linux equivalent of Mac OS X’s textutil? … read here.
