When I read articles online I often wish to save it as a PDF for reference. In Safari on iOS I use the “reading mode” (the four lines in the address bar) and the “create pdf” share. I save the articles to a folder, and Safari names them by default to “SafariViewService” with a datetime.
In order to find the relevant articles again, I have made a Hazel rule to rename the file based on the content, a custom field set to “everything”. This takes the first line of the file (usually the headline) and uses this as the filename. That’s all well and fine.
Except that for some files there are leading spaces, which isn’t nice. And I can simply not find a way, within Hazel, to get rid of these. I can identify files with a leading space, but cannot find a way to rename it without the spaces. I see the character categories, but it seems that full regex is not implemented (that would make life easier…)
