Used by templates / Uzata far sxablonoj /
Digunakan oleh templat / Anvaent av mallar:
* "montablng" (EO) / "mpltabbah" (ID)

Required submodules / Bezonataj submoduloj / Submodul yang diperlukan:
* "loaddata-tbllingvoj" T78 in turn requiring template "tbllingvoj" (EO)

Incoming: * 2 parameters
            * anonymous obligatory parameter
              * string with 2 or 3 char:s -- language access code
            * named obligatory parameter
              * "infsel=" control string for lines -- 6 digits (boolean
                 options: "0" do not show | "1" show and query |
                 value "2" NOT available here)

                * "d09" "ind" index

Returned: * one big string

This module is unbreakable (when called with correct module name
and function name). Every imaginable input from the caller and
from the imported module "loaddata-tbllingvoj" will output either
a useful result or at least the string "Grava eraro".

Cxi tiu modulo estas nerompebla (kiam vokita kun gxustaj nomo de modulo
kaj nomo de funkcio). Cxiu imagebla enigo de la vokanto kaj

utilan rezulton aux almenaux signocxenon "Grava eraro".

In "msngtbllin" we walk down and for every d-item /d00/ ... /d13/ we brew a
row with two cells title and content. In "bigtable-tbllingvoj" "mkomtbllin" we
walk right and for every d-item /d00/ ... /d13/ we brew one cell in a column.

Note that the parameter "infsel=" (control string with 6 char:s) has almost
same function in both "bigtable-tbllingvoj" "mkomtbllin" and "msngtbllin", but
some of the values are tristate in "bigtable-tbllingvoj" "mkomtbllin", whereas
all are boolean in "msngtbllin", and querying is always on.

It is possible to control whether to show link to appendix page in "d09"
or not. This is provided for consistency with "mkomtbllin", but since
this module "msngtbllin" is supposed to be called from exactly those
appendix pages (via "montablng" or "mpltabbah"), this subparameter will
usually be false ie "0".

Line numbering in the source table:
- numbering starts from ZERO
- /cy/ does not count (it has theoretically index "-1")
- note that there is no comma between /cy/ and /c0/

Structure of a line in the source table with 1+11 values
for 1+11 lines in the generated table:
- /cy/ : y-index marker (2 or 3 digits)
- /c0/ : name of the language in the site language
         * EO: usually AJ lowercase, alternatively SB uppercase begin
         * ID: without "bahasa " and begins with uppercase letter
- /c1/ : QID (for example "Q5432") "Q" + 2...8 digits, earliest digit
         "1"..."9", further digits "0"..."9"
- /c2/ : name of the language in the language itself
         ("propralingve")
- /c3/ : constructed and antique status (digit "0"..."3")
- /c4/ : ISO 639-1:2002 2-letter code (only lowercase)
- /c5/ : ISO 639-3:2007 3-letter code (only lowercase)
- /c6/ : wiki access code, itself usually same as /cy/, but may be different
         and longer up to 10 char:s, for example "zh-min-nan", leave it "-"
         here if code is same or unknown, use "??" if code belongs to
         other language ("als.pedia.org")
- c7 : wiki availability code (2 digits "0"..."2" ie "00"..."22"),
       "-" causes reddish background and no info about availability
- c8 : name of ipedia article, base principle usually
       followed (there are some exceptions):
       - EO: core word usually AJ name with uppercased begin
             followed by " lingvo", no "la" article
       - ID: prefixed by "Bahasa " and core word begins with uppercase letter
- c9 : category with our site language ("eo" or "id") in other tionary
       (with category NS prefix, but without language prefix, without "]]"
       or other nonsense, can be absurdly long
       "Rummad:Wikeriadur:Distagaduriou' a vank en indonezeg" has 52
       octet:s and even worse 2 apo:s)
- ca : number of pages in that category, apo:s ("16'384") are
       tolerable (this cannot be peeked automatically)
Note that /cy/ and /c0/ are ultimately obligatory, the remaining
ones are only highly desirable.

Overall structure of the generated destination table:
* title cell "colspan=2" with fixed string (big, bold, no link)
* body part
  * 14 rows per 2 cells with info
     or
  * one single cell "colspan=2" with lagom error #E12 "Nekonata lingvokodo"
* bottom cell "colspan=2" with update/purge link (depends on pagename)
  and link to source table (fixed) and link to complete table (fixed)

Structure of the right column in the destination table with 14 rows:
- /d00/ : * incoming language access code (bold) only if valid and found
          # adjust background for "eo" only
- /d01/ : * name of the language in the site language with link to the
            lemma page (name literally peeked from /c0/ in the source table,
            must be available and valid, link augmented by "lfiultpl5repl"
            according to control string "contabpages[0]")
- /d02/ : * QID (for example "Q5432")
- /d03/ : * name of the language in the language itself
            (literally peeked from /c1/ in the source table)
- d04 : - constructed and antique status (expanded from digit "0"..."3"
          peeked from "c2" in the source table)
        # adjust background to greenish or grey if applicable
- d05 : - "ISO 639-1:2002" 2-letter langcode
          (literally peeked from "c3" in the source table)
- d06 : - "ISO 639-3:2007" 3-letter langcode
          (literally peeked from /c4/ in the source table)
- d07 : - ? link to the "tln" top lng category in own tionary if
            desired, no page count here
        - ? EOL (only if both cat:s are desired)
        - ? link to the "kap" category in own tionary with all words in
            the language (constructed from constant string "strpikkatns"
            (category namespace prefix without ":") and /c0/ augmented by
            "lfiultpl5repl" according to control string "contabpages[6]")
          - ? EOL (if complaint below exists)
          - ? complaint about not existing if applicable
          - ? EOL (if the "parent" link to the "kap" category is present)
          - ? number of pages (queried) or "??" if querying does not work
        # adjust background to reddish if the category (one of two)
          does not exist
        ! depends on variables "tabctl.tlnsow" and "tabctl.tlnexp" and "tabctl.kapsow"
          and "tabctl.kapexp" and includes expensive querying (2), column
          can be completely hidden by "tabkol.d07"
- d08 : - ? link to the "vor" category in own tionary with all dictionaries in
            the language (constructed from constant string "strpikkatns"
            (category namespace prefix without ":") and /c0/ augmented by
            "lfiultpl5repl" according to control string "contabpages[3]"), no
            page count here
        - ? EOL (only if both cat:s are desired)

          - ? EOL (if complaint below exists)
          - ? complaint about not existing if applicable

        ! depends on variables "tabctl.vorsow" and "tabctl.vorexp" and "tabctl.malsow"
          and "tabctl.malexp" and includes expensive querying (2), column
          can be completely hidden by "tabkol.d08"
- d09 : - link to the appendix page (constructed from constant string
          "strpikapxns" (appendix namespace prefix without ":") and /c0/
          augmented by "lfiultpl5repl" according to control string
          "contabpages[1]") controlled by "tabctl.apxsow"
        - EOL (only if both pages are desired)
        - link to the index page in own tionary with
          the language (constructed from constant string "strpikindns"
          (index namespace prefix without ":") and /c0/ augmented by
          "lfiultpl5repl" according to control string "contabpages[2]")
        # adjust background to reddish if at least one of them does not exist
        ! depends on variables "tabctl.apxsow" and "tabctl.apxexp" and "tabctl.indsow"
          and "tabctl.indexp" and includes expensive querying (1), column
          can be completely hidden by "tabkol.d09"
- d10 : - quasi-external link to wikipedia in the language concerned
          (constructed from "c5" and "c6" and /cy/, irrespective availability)
        - EOL (if note below exists)
        - note about bad availability if applicable
        # adjust background to grey according to bad availability
        ! no expensive querying here
- d11 : - quasi-external link to tionary in the language concerned
          (constructed from "c5" and "c6" and /cy/, irrespective availability)
        - EOL (if note below exists)
        - note about bad availability if applicable
        # adjust background to grey according to bad availability
        ! no expensive querying here
        & special rule ie blocking for own site language
- d12 : - quasi-external link to the article in own ipedia about the language
          (article name constructed from "c7", or alternatively if "c7" is
          not available then it is guessed using "lfiultpl5repl" from /c0/
          and "contabpages[7]" and " (??)" is added)
        # adjust background to reddish if "c7" is not available
        ! no expensive querying here
- d13 : - quasi-external link to EO or ID category in the tionary in the
          language concerned (peeked from "c8" in the source table)
        - EOL (if number of articles below exists)
        - number of articles (peeked from "c9" in the source table)
        # adjust background to reddish if "c8" or "c9" is not available
        ! no expensive querying here
        & special rule ie blocking for own site language

Expensive querying: !!!FIXME!!!
There are 6 expensive queries (2 cat:s plus appendix plus index, one cat
costs 2 bucks ("ifexist" and "pagesincategory") per page, appendix and index
cost one buck per page) per language and thus per table row. This is a big
problem in "bigtable-tbllingvoj" "mkomtbllin" but here in "msngtbllin"
it is no problem at all.

Error handling (here in "msngtbllin" we are much stricter than
"bigtable-tbllingvoj" "mkomtbllin" is and do NOT show broken stuff, and do NOT
use red background, but reddish background is still applied when appropriate):
- argument supplied from the caller is bad, or neither the requested language
  nor our own language could be
  peeked, or the peeked complete line contains syntax errors,
  output is minimal with huge error "Grava eraro" then, no big table
  (replace the output string if we already began to brew the table)
- #E12 unknown langcode still show table with lagom "Nekonata lingvokodo"
- if there are too many elements in a line then we ignore the
  superfluous ones
- if there are too few elements (but at least one ie /c0/) in a line
  then we show "-" (not "=") and adjust the background color in
  cells not getting any content
- if /c0/ is not available then #E15 "Grava eraro"
- if "mw.title.getCurrentTitle().prefixedText" does not reveal our
  pagename (needed for purge link) then we don't whine but use a bad
  default "Special:Recent changes" instead

Errors codes in "numerr":
* #E01 -- internal
* #E02
* #E03
* #E08 -- number of anon param
* #E11 -- obviously invalid langcode from anon param {{{1}}} (only msng)
* #E12 -- unknown langcode from anon param {{{1}}} (only msng,
          only error showed inside table)
* #E13 -- anon param {{{1}}} boolean is bad (only big)
* #E14 -- anon param {{{2}}} integer is bad (only big)
* #E15 -- fatal (only msng)
* #E16 -- named param "infsel=" missing
* #E17 -- named param "infsel=" invalid
