Publish multiple Markdown files to HTML in Windows
Scribbled · PDF · ◊Pollen source
I wrote this script as a means of setting up a dead-simple “knowledge base” in HTML format.
The idea is to write documentation as a collection of plain-text files in Markdown format and have a no-fuss way to publish them as HTML, re-publishing changes as necessary.
In order for this script to work, you need to be on Windows, and you need to install a program called pandoc
.
How to use it:
- Save a copy of this script file in any folder containing a bunch of Markdown-formatted text files. Include a
stylesheet.css
file in this folder as well if you want the HTML files to have CSS styling. - Run the script (double-click it)—it will silently create updated HTML files for every text file in the folder. Only text files whose HTML counterparts are out of date or nonexistent will be processed.
You can either copy and paste the code below into Notepad and save it as a .vbs
file, or you can download the latest version in a zip file. The code in the download will be more extensively commented, and may also contain enhancements developed since this post was written.
Here’s the basic code (provided under the terms of the Artistic License 2.0—http://www.perlfoundation.org/artistic_license_2_0):
Set objShell = CreateObject("WScript.Shell") Set objFSO = CreateObject("Scripting.FileSystemObject") strThisFolder = objFSO.GetParentFolderName(Wscript.ScriptFullName) Set objStartFolder = objFSO.GetFolder(strThisFolder) strConverterCommand = "pandoc -f markdown -t html -c stylesheet.css -o " Set objFilesToUpdate = CreateObject("Scripting.Dictionary") Set colFiles = objStartFolder.Files For Each objFile in colFiles If objFSO.GetExtensionName(objFile.Name) = "txt" Then ' Check if HTML version of this text file exists in this folder strHTMLName = strThisFolder & "\" & Replace(objFile.Name, ".txt", ".html") If objFSO.FileExists(strHTMLName) Then ' If it exists, compare the timestamps Set objHTMLFile = objFSO.GetFile(strHTMLName) If objFile.DateLastModified > objHTMLFile.DateLastModified Then 'If the text file is newer, add this text file to the list objFilesToUpdate.Add objFile.Name, strHTMLName End if Else ' If the file does not exist yet, add this text file to the list objFilesToUpdate.Add objFile.Name, strHTMLName End if End if Next ' Update all the text files in the list. colFilesToUpdate = objFilesToUpdate.Keys For Each strSourceFile in colFilesToUpdate objShell.Run strConverterCommand & objFilesToUpdate.Item(strSourceFile) & " " & strSourceFile, 3, True Next
Possible Future Improvements:
- The script isn’t very helpful about telling you how long the process is going to take. I looked at several options for providing a progress bar or some kind of status output, but ultimately VBScript is just really sucky at this.
- Pandoc is a very powerful converter. One could easily tweak the script to add options for producing LaTeX or even PDF files.
