Adding data-pos info to latex output

As described here, Pandoc records Synctex-like information when the source is commonmark+sourcepos. For example, with this commonmark input,
---
title: "Sample"
---
This is a sample document.
the output in native format starts like this:
Pandoc
Meta
{ unMeta =
fromList [ ( "title" , MetaInlines [ Str "Sample" ] ) ]
}
[ Div
( "" , [] , [ ( "data-pos" , "Sample.knit.md#5:1-6:1" ) ] )
[ Para
[ Span
( ""
, []
, [ ( "data-pos" , "Sample.knit.md#5:1-5:5" ) ]
)
[ Str "This" ]
, Span
( ""
, []
, [ ( "data-pos" , "Sample.knit.md#5:5-5:6" ) ]
)
[ Space ]
, Span
( ""
, []
, [ ( "data-pos" , "Sample.knit.md#5:6-5:8" ) ]
)
[ Str "is" ]
but all that appears in the .tex file is this:
{This}{ }{is}...
As a step towards Synctex support, I'd like to insert the data-pos information as LaTeX markup, i.e. change the .tex output to look like this:
{This\datapos{Sample.knit.md#5:1-5:5}}{ \datapos{Sample.knit.md#5:5-5:6}}{is\datapos{Sample.knit.md#5:6-5:8}}...
This looks like something a Lua filter could accomplish pretty easily: look for the data-pos records, copy the location information into the Str record. However, I don't know Lua or Pandoc native language. Could someone help with this? Doing it for the Span records would be enough for my purposes. I'm using Pandoc 2.18 and Lua 5.4.
Here is an attempt that appears to work. Comments or corrections would still be welcome!
Span = function(span)
local datapos = span.attributes['data-pos']
if datapos then
table.insert(span.content, pandoc.RawInline('tex', "\\datapos{" .. datapos .. "}"))
end
return span
end

Google sheets Array Formula IF Statement

I'm trying to run an array formula to see how long (days) it is in a current status.
Source:
={
"Days since application submitted";
ArrayFormula(
If(
Isblank(U3:U),
"",
(
IF(
G3:G="APPLICATION SENT",
DATEDIF(U3:U,AA3:AA,"D"),
(
IF(
G3:G="APPLICATION ACCEPTED - AWAITING REPAYMENT",
DATEDIF(U3:U,AF3:AF,"D"),
(
IF(
G3:G="CREDIT",
DATEDIF(U3:U,AF3:AF,"D"),
(
IF(
G3:G="COMPLETED",
DATEDIF(U3:U,AF3:AF,"D"),
)
)
)
)
)
)
)
)
)
)
}
It works fine however if I don't have anything in column 'AF' as I may skip a status it will show up with an error. But if 'AF' is blank I then want to do another check within the same array formula to run something like (IF(ISBLANK(AF3:AF),"",(IF(G3:G="COMPLETED",DATEDIF(U3:U,AJ3:AJ,"D") ... Looking at another date in 'AJ' column.
={
"Days since application submitted";
ArrayFormula(
If(
Isblank(U3:U),
"",
(
IF(
G3:G="APPLICATION SENT",
DATEDIF(U3:U,AA3:AA,"D"),
(
IF(
G3:G="APPLICATION ACCEPTED - AWAITING REPAYMENT",
DATEDIF(U3:U,AF3:AF,"D"),
(
IF(
G3:G="CREDIT",
DATEDIF(U3:U,AF3:AF,"D"),
(
IF(
G3:G="COMPLETED",
DATEDIF(U3:U,AF3:AF,"D"),
OR(
if(
isblank(
AF3:AF,
IF(
G3:G="COMPLETED",
DATEDIF(U3:U,AJ3:AJ,"D"),
)
)
)
)
)
)
)
)
)
)
)
)
)
)
}
Any support would be helpful where I am going wrong.
Instead of nesting many if() functions, try ifs(), like this:
=arrayformula(
{
"Days since application submitted";
ifs(
isblank(U3:U),
iferror(1/0),
isblank(AF3:AF) * (G3:G = "COMPLETED"),
datedif(U3:U, AJ3:AJ, "D"),
G3:G = "APPLICATION SENT",
datedif(U3:U, AA3:AA, "D"),
regexmatch(to_text(G3:G), "(?i)accepted|credit|completed"),
datedif(U3:U, AF3:AF, "D"),
true,
na()
)
}
)
try:
={"Days since application submitted"; ARRAYFORMULA(
IF(ISBLANK(U3:U),,
IF(G3:G="APPLICATION SENT", DATEDIF(U3:U, AA3:AA, "D"),
IF(ISBLANK(AF3:AF),,
IF(REGEXMATCH(""&G3:G, "APPLICATION ACCEPTED - AWAITING REPAYMENT|CREDIT|COMPLETED"),
DATEDIF(U3:U, AF3:AF, "D"))))))}

parametric data types in z3py

Does z3py have functions to create a parametric data type, like what would be generated using the following SMTLIB code?
( declare - datatype List ( par ( T )
( ( nil ) ( cons ( car T ) ( cdr ( List T )) ))))
Yes. See here: https://ericpony.github.io/z3py-tutorial/advanced-examples.htm
Search for the section titled "Datatypes."
Here's the example right from that page, that does exactly what you want:
def DeclareList(sort):
List = Datatype('List_of_%s' % sort.name())
List.declare('cons', ('car', sort), ('cdr', List))
List.declare('nil')
return List.create()
IntList = DeclareList(IntSort())
RealList = DeclareList(RealSort())
IntListList = DeclareList(IntList)

I am using this loop for to get all objects and save into single Array:
for (int i = 0 ; i < dataArray.count; i++){
for (int j = 0 ; j<[[dataArray objectAtIndex:i] count]; j++) {
total addObject:[dataArray objectAtIndex:j]];
}
}
Using C-style iteration is not absolutely necessary, here's what you could do:
for(id object in dataArray) {
for(id subobject in object) {
[mutableArray addObject:subobject];
}
}

Encrypting a database in Lua

I am working with a database I am trying to make secure. I have been able to create the database and access the information within it. However once I try to encrypt the individual pieces of information within the database I run into trouble. I am using sqlite3 for my database and openssl to try to encrypt the database.
local users = [[CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, username, password);]]
db:exec( users )
local nameData = cipher:encrypt ( nameField.text, "sbs_math_key" )
local passData = cipher:encrypt ( passwordField.text, "sbs_math_key" )
local tablefill =[[INSERT INTO users VALUES (NULL, ']].. nameData ..[[',']].. passData ..[['); ]]
db:exec( tablefill )
This works if I am inserting into an existing database, however if I am creating a new database it won't let me insert the encrypted information.
Try this:
local nameData = mime.b64 ( cipher:encrypt ( nameField.text, "sbs_math_key") )
local passData = mime.b64 ( cipher:encrypt ( passwordField.text, "sbs_math_key") )
print( "Before : "..nameData )
local tablefill =[[INSERT INTO users VALUES (NULL, ']].. nameData ..[[',']].. passData ..[['); ]]
db:exec( tablefill )
message = cipher:decrypt ( mime.unb64 ( nameData ), "sbs_math_key" )
print( "After : "..message )
