The worksheet's realm does not change, and is not shared, so we can
safely leave the global environment be.
This fixes lexical scoping in the spreadsheet's runtime file.
Also add slightly richer parse errors now that we can include a string
literal with returned errors.
This will allow us to use TRY() when working with JSON data.
Because we declare the functions in runtime.js we need the correct
global object to be setup otherwise they cannot be accessed when
switching to the SheetGlobalObject.
Before this commit it only allocated the global object so when it wanted
to lookup 'thisSheet' it could not find it in the global environment.
We now hotswap the global object everytime a cell evaluated.
This also fixes that SheetGlobalObject did not have an
internal_has_property meaning 'A0' could not be referenced unless it was
via a member lookup (this.A0). This was already broken before the
bindings refactoring.
The correct behavior of realms in spreadsheet is not completely clear
since what is shared between sheets is not very well defined.
The reason that just setting the SheetGlobalObject as the
global_this_value is not enough is because ECMAScript does not check the
global_this_value for members when resolving a reference in the global
environment.
Earlier, we were using 0 value for characters not found in "map".
We should return failure for invalid inputs.
So, I have changed the return type of function to Optional<size_t>.
Also changed caller to handle Optional return.
Fixed convert_from_string() function to return correct output.
The value of a number is equal to sum of each digit multiplied by it's
positional weight.
This removes all usages of the non-standard put helper method and
replaces all of it's usages with the specification required alternative
or with define_direct_property where appropriate.
This removes StringView::find_first_of(char) and find_last_of(char) and
replaces all its usages with find and find_last respectively. This is
because those two methods are functionally equivalent.
find_{first,last}_of should only be used if searching for multiple
different characters, which is never the case with the char argument.
This also adds the [[nodiscard]] to the remaining find_{first,last}_of
methods.
This removes JsonObject::get_or(), which is inefficient because it has
to copy the returned value. It was only used in a few cases, some of
which resulted in copying JsonObjects, which can become quite large.
This changes JsonObject to use the new OrderedHashMap instead of an
extra vector for tracking the insertion order.
This also adds a default value for the KeyTraits template argument in
OrderedHashMap. Furthermore, it fixes two cases where code iterating
over a JsonObject relied on the value argument being copied before
invoking the callback.
Updated Spreadsheet to use the new way of converting a number to a
String represenation using the alphabet.
The code responsible for this conversion now lives in AK/String, so it
gets deleted from Spreadsheet.cpp.
Instead of storing the function names (in a badly named Vector<String>)
and source ranges separately, consolidate them into a new struct:
TracebackFrame. This makes it both easier to use now and easier to
extend in the future.
Unlike before we now keep each call frame's current node source range
in the traceback frame next to the function name, meaning we can display
line and column numbers outside of the VM and after the call stack is
emptied.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

This was done with the `ambr` search and replace tool.
ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
This broke in 6a6f19a72f, which replaced
the representation of columns with numbers.
As a result, the save logic would store cells as
"\x<column_index><row_number>", which is obviously wrong.
Fixes#5905.
Also simplifies the control flow in `import_worksheet` a bit.
There won't be any parse errors before we actually try to parse
something.
Fixes input like "=1+" crashing the spreadsheet instead of just causing
an error in the cell.
Commit 6a6f19a72 broke the cell position display in the top left of the
Spreadsheet window and the title of the cell type dialog, causing the
application to crash when interacting with cells beyond column FE.
This will make constructing (and destructing) Positions a lot cheaper
(as it no longer needs to ref() and unref() a String).
Resulted from #5483, but doesn't fix it.
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
