15 # Basic catalog generator for Nit packages
17 # See: <http://nitlanguage.org/catalog/>
19 # The tool scans packages and generates the HTML files of a catalog.
23 # * [X] scan packages and their `.ini`
24 # * [X] generate lists of packages
25 # * [X] generate a page per package with the readme and most metadata
26 # * [ ] link/include/be included in the documentation
27 # * [ ] propose `related packages`
28 # * [X] show directory content (a la nitls)
29 # * [X] gather git information from the working directory
30 # * [ ] gather git information from the repository
31 # * [ ] gather package information from github
32 # * [ ] gather people information from github
34 # * [ ] separate information gathering from rendering
35 # * [ ] move up information gathering in (existing or new) service modules
36 # * [X] add command line options
37 # * [ ] harden HTML (escaping, path injection, etc)
38 # * [ ] nitcorn server with RESTful API
40 # ## Issues and limitations
42 # The tool works likee the other tools and expects to find valid Nit source code in the directories
44 # * cruft and temporary files will be collected
45 # * missing source file (e.g. not yet generated by nitcc) will make information
46 # incomplete (e.g. invalid module thus partial dependency and metrics)
48 # How to use the tool as the basis of a Nit code archive on the web usable with a package manager is not clear.
