jod todo list JOD TODO

Pending and considered changes for JOD and its subclasses. The base 36 GUID key is stable over the lifetime of a task. Browse the revision history of this file to review changes. Also, read history.md to see what actually got implemented. Plans do not necessarily materialize.

[begin-todo]

  1. <_82d0nudx1m2go87v4x0ty9fkx_> Consider adding a formating option to make that generates direct definition forms when making scripts. The direct definition form is more elegant and has the nice feature of "dequoting" single line explicits, e.g.

    NB. quoted standard explicit
rsvdec=: 3 : ']`(NULLMARK"_)@.((,RSVNULL)&-:)L:0 <;._2&.> <;._2 y'
NB. dd form
rsvdecdd=: {{ ]`(NULLMARK"_)@.((,RSVNULL)&-:)L:0 <;._2&.> <;._2 y }}

    The conversion from standard explicit to dd is straightforward as long as the definition does not use any of J's reserved argument names, u v m n. A change like this would also impact jodliterate but overall would make J code nicer to look it.

  2. <_dxkdc53xna97v1culec8kqx0y_> Consider adding two new configuration options. One to turn on/off direct definition formating and control it, another to turn on/off various warnings and control it.

    NB. turn on direct definition formatting
dpset 'DIRECTDEF';0  NB. turn off ddefs - current behaviour and default
dpset 'DIRECTDEF';1  NB. format (make) results as direct definitions
dpset 'DIRECTDEF';2  NB. format as direct definition turn off `)declarations` , e.g. {{) d x +y}} is {{x + y}}
dpset 'WARNINGS';0   NB. turn off warnings
dpset 'WARNINGS';1   NB. turn warnings on - messages when x y u v m n used as locals

  3. <_3bq9v9yst3qu3t62zicli27gv_> New numeric datatypes and a conversion utility c. are being added in J 9.6 (2024jan02) we now have /integer1/integer2/integer4/floating2/floating4/floating16 whenever there are changes to binary internals it impacts JOD. I've already hit a conversion precision error. The serial dump format usually works going forward but I am concerned about creating dump scripts that will not load in older J versions. Will have to devise some scheme to cope. NOTE: seems to have been fixed in later J 9.6 betas. EYESOPEN!!

  4. <_botm3t2vdtw7ite6kkyyi014v_> J's file verbs may hang when accessing windows files on drives accessed by VPN connections when VPN is off. There's not much JOD can do for mapped (letter'ed) drives but fexist eventually returns 0 for VPN shares like:

     fexist '//jfsdev04/shares/jod/jod/jwords.ijf'

    JOD could do a quick existence check on windows systems when it sees unmapped shares //some/share/ehh/jwords.ijf. This will not help for VPN mapped drives when VPN is off. EYESOPEN!!

  5. <_31t8dofxlypuuaflswoq784pp_> Test jodliterate on macOS and linux. Tweak if needed.

  6. <_77ozevqhpzugqsgru959hbqp2_> Improve and extend JOD labs and insure they run on later J systems. Labs have changed in recent J versions.

  7. <_d1dtfkd14ypvlatnch2pa5hwo_> Consider allowing ~/ as a path prefix on macOS and Linux systems. The home directory convention on these systems is respected by dir.
