Should do: - Should be a better way code the various tree formats (XML/HTML/Unix) to share more code. Probably make a generic tree crawling routine that calls various function pointers to emit the file information based on the kind of tree we want. - Make wide character support less of a hack. - Fully support HTML colorization properly. - Go over the -R option for HTML output and make it cleaner & less of a hack. Should do -R internally so we don't have to rebuild a command line or use something awful like system(). Should be doable by saving some state and recursing and also separating out parts of main. - Should probably make it so that options like -p, -u, etc print out info for the top directory, if people think that would be desirable. - Might be nice to prune files by things like type, mode, access/modify/change time, uid/gid, etc. ala find. - Just incorporate the stat structure into _info, since we now need most of the structure anyway. Maybe do: - With the addition of TREE_COLORS, add some custom options to perhaps colorize metadata like the permissions, date, username, etc, and change the color of the tree lines and so on. - Make tree look for a .comments file in a directory and append the text from that file to the output of the files and directories, so that the output looks like Slackware's README file, like: > tree -F --comments ... |-- kernels/ Precompiled Linux 2.6.37.6 kernel images. | | | |-- hugesmp.s The default standard install kernel for Slackware. | | This supports pretty much everything in the | | 2.6.37.6 kernel, and includes support for Speakup. | | This kernel requires at least a Pentium-Pro processor. | | | `-- huge.s A single-processor version of huge.s that will | function with older hardware such as a 486 with | 128MB (64MB _might_ work) or more of RAM. | This kernel also supports Speakup. ... Might be particularly nice for the HTML output, where the comments could be made as mouse-over popups or the like.
