Markdown "single page" PHP web application with live preview?

2

I would like to know if there is a PHP web application, such that

  • When called with something like http://example.com/index.php?inputfile=mymarkdownfile.txt; it will open the file mymarkdownfile.txt at the same location as index.php on the webserver, and render it as Markdown (i.e., it will convert the Markdown to HTML and serve it)
  • There will be an "edit" button, which opens a "live preview" Markdown editor (like on StackExchange/StackOverflow sites)
  • When you're done editing and click on the "save" button, previous version is archived on server (saved as text file mymarkdownfile-timestamp.txt), and the changed version is saved as mymarkdownfile.txt.
  • If you try to "open" a "nonexisting file" (say, via http://example.com/index.php?inputfile=nonexistant.txt), then the editor starts first; and the content typed there will be saved as nonexistant.txt (and nonexistant-timestamp.txt)

I just need this for server based note taking, and I don't really need local linking or anything like that; nor user authentication nor protection (I'd intend to use this on local network, so I wouldn't be worried about public exposure of "edit" button and vandalism).

I imagine it could be a PHP page, which uses:

Anything like that out there?

Many thanks in advance for any answers,
Cheers!

I was looking for exactly this a while ago. Didn't find it. Settled with markdoc.

I also looked at jekyll. And I use MarkdownPad for editing. Sadly not even close to what I (and you) originally wanted. But it works. History can be provided by VCS like git if the product doesn't have anything built in. Good luck! :)

Thanks for those references too, @OliverSalzburg - since apparently there is nothing else, I put something together, please see answer below. Cheers!

Well, given that I really needed something like this, I put together a small PHP script/application that does the above; called it the Single-page Markdown Web Editor (spmdwe); please see:

Hope this helps someone,

Thanks for building this. It's just what I was looking for (mainly for checking the rendering of markdown as I enter it). I presume it wouldn't be too much of a mission to adapt to load/save data to/from a tuple in a database instead of a file. – Agi Hammerthief – 2014-11-11T19:00:35.540

Also, your code doesn't sanitize input retrieved from $_REQUEST[] before outputting it directly. You should do something about that. – Agi Hammerthief – 2014-11-11T19:10:25.843

Based on this useful application, I developed a new one. It has a nicer interface and more functions like history, download file, mark a file as read-only and view and editing modes. It is available here: http://www.spmdwe.tk/ The repository is available here: https://github.com/rigon/notes
