Since 1 June 2012, I've been taking notes in unicode text files, which contain (occasional or adjacent) lines starting with 'nb ' and then a list of tags. I wrote a simple tool ("nb") in Inferno's shell (thanks to Robert J. Ennis for the port to Plan 9's rc), to (1) search for given keywords in per-directory index files pointed to by the global index, (2) index all of the nb lines in files in the current directory, and (3) if necessary, append, to a global index file, a reference to the index file in the current directory. https://github.com/catenate/notabene I've found that I'm comfortable with the eventual consistency this offers, in exchange for fast lookups when I want something (as opposed to indexing first, and/or indexing globally, and so waiting for indexing to get a result). This distributed-file approach also allows me to add tags to a variety of files: local files, or networked file-system files, or sshfs-mounted files, or Dropboxed files, or files under version control, or files with varying text formats; and find tags across all of them and across all the time I've been indexing. It runs in linear time with respect to the number of tags I've entered, plus the time to read and process the global index, so obviously there are many ways I could improve the time performance (as an easy example, I could permute the index to list all the tags in alphabetical order, and next to each tag list the files that contain that tag). I also wrote other tools, since the layout is so simple: for example, "nbdoc", to catenate the actual contents of the references returned by the primary tool (nb); and "so" (second-order), to return all the tags which appear in any nb line with the given tag(s). I've also found that it's not easy for me to remember what tags I might have used in the past, or how I was thinking about something, so I try to use the conjuction of several tags to narrow down search results, rather than try to remember one specific tag (this seems to correspond to the observation that it can be difficult to remember exactly where in a hierarchy you put something). The modular approach, of per-directory indexes referenced in a global file, also makes it easy for me to combine work-specific notes, with public notes, with private notes, all in the same global index file, at work; but only have the same public and private notes at home. |
