# pending tasks and loose ideas
## flexible patterns
* test each pattern (not only the default combined pattern)
* add option to generate either minimal or maximal pattern
* minimal: shortest coverage decisive of one or more objects.
* distinct: shortest coverage to disambiguate from unrelated objects
and objects it depends on,
and large enough for dependent objects to disambiguate from it.
* successive: minimal or distinct + surplus up until next ambiguation point
* maximal: full coverage
## misc
* Support adding custom patterns
to enable frontend to to implement extensibility similar to license-reconsile
<https://lists.debian.org/87efl0kvzu.fsf@hands.com>
* Support smarter processing:
* Gather statistics on objects detected,
to enable a frontend tool to emit progress during long-running scans
* Detect non-commercial license.
(?i:(?:\w{4}|\W(?:[^oO]\w|\w[^rR]|[^aA]\w\w|\w[^nN]\w|\w\w[^dD])) non[-_ ]commercial)
* Detect bugroff license <http://tunes.org/legalese/bugroff.html>

## misc
* Optimize:
+ Support detection reversion, and first scan for grants then licenses - reverting embedded grants
* Test against challenging projects
+ ghostpdl
+ chromium
+ fpc
+ lazarus
+ boost
+ picolibc <https://keithp.com/cgit/picolibc.git/>
* Support smarter interogation
* Provide methods to inspect position of detected objects
to enable frontends to e.g. visualize using String::Tagged or Text::Locus
* Detect quality issues
+ incomplete: fractions of license fullref, but no complete fullref
+ alien: license label but no license name
+ uncertain: license ref and more unknown text in same sentence/paragraph/section
+ buried: license not at top of file
+ unstructured: license not at ideal place of data structure
(e.g. in content or comment of html)
+ imperfect: license ref not following format documented in license fulltext
* use nano-style configurable wordchars/punct/brackets/matchbrackets chars and quotestr regex
e.g. to determine sentences
(see "paragraphs" and "justify" in "man nanorc")
