[TxMt] markdown_to_help.rb image problem + a suggestion

[Hans-Joerg Bibiko]

Hi,

in the list I mentioned the problem that if you want to put images in  
a help file written in markdown and using 'markdown_to_help.rb' for  
formatting you will loose the reference for these images.

Allan mentioned to echo the base href in beforehand but then the  
internal links generated by 'markdown_to_help.rb' don't work.

To solve this problem here my suggestion for an easy solution:

In your markdown file you write e.g.

![Hypersearch dialog](images/getall.png)

It is a relative path, so you can see the image with 'Show Web  
Preview' while writing your markdown

In your command to display the help you can write:

. "$TM_SUPPORT_PATH/lib/webpreview.sh"

html_header "Hypersearch Bundle Help" "Hypersearch"

"$TM_SUPPORT_PATH/lib/markdown_to_help.rb"  
"$TM_BUNDLE_SUPPORT/help.markdown" | perl -npe  
's/(.*?<img.*?src=")(.*?)(".*)/$1file:\/\/$ENV{"TM_BUNDLE_SUPPORT"}\/$2$3/gi'

html_footer


What I'm done here is to pipe the output of 'markdown_to_help.rb' to a  
perl command which puts at the beginning of each relative path in src  
within a img tag the absolute path 'file:///$TM_BUNDLE_SUPPORT/'.

This perl command, of course, could be also implemented within  
'markdown_to_help.rb' or as TM wide standalone command written in  
Ruby, Perl, or whatever (which I would prefer for speed).


Cheers,

Hans
