Álvaro Ramírez continues his roll with yet another function for his dwim-shell-command framework. This time, it’s a function to combine several .png files into a single .pdf file. As with the other functions, the point is not to enable new functionality but to make complicated invocations of existing programs easy to remember and use.
As Ramírez says, while it can be hard to remember the command to use for some action, dwim-shell-command lets you name the task, which is easier is to remember, and capture complicated parameters for the process.
As I’ve written before, the dwim-shell-command package is now available on Melpa and Ramírez has broken out the framework code from the individual shell commands that he’s written. That makes it a bit easier if you’re not interested in his functions but want to write your own.
If you frequently invoke commands from the shell with hard to remember names and complex calling sequences, you should definitely take a look at this package.
