Text editor which can run external conversion program

Question

Hello All

BeyondCompare has this conversion feature which can run an external program on certain file type and open the file generated. For eg. If a file has format *.abc which is a binary file and if i have an external program which reads this binary and convert it to text with a different extension like *.xyz, i can associate beyondcompare to compare *.xyz(text) though i open *.abc(binary) files.

I wanted to know if there's such text editor available. When i open a *.abc(binary) file, the editor should run the external program to convert *.abc to *.xyz(txt) and open *.xyz instead. Tried searching for this in net but no leads there.

Thx

vim can do this. In your vimrc resource file:

:au BufRead *.foo :!sed 's/a/o/g' % > %:r.bar
:au BufRead *.foo :edit %:r.bar
