Subject: [PATCH 008/266] SimpleChatTC: Skeleton to handle diff fields when
 streaming

Changed latestResponse type to an object instead of a string.
Inturn it contains entries for content, toolname and toolargs.

Added a custom clear logic due to the same and used it to replace
the previously simple assigning of empty string to latestResponse.

For now in all places where latestReponse is used, I have replaced
with latestReponse.content.

Next need to handle identifying the field being streamed and inturn
append to it. Also need to add logic to call tool, when tool_call
triggered by genai.

Subject: [PATCH 009/266] SimpleChatTC: Extract streamed field - assume only 1f
 at any time

Update response_extract_stream to check for which field is being
currently streamed ie is it normal content or tool call func name
or tool call func args and then return the field name and extracted
value.

Previously it was always assumed that only normal content will be
returned.

Currently it is assumed that the server will only stream one of the
3 supported fields at any time and not more than one of them at the
same time.

TODO: Have to also add logic to extract the reasoning field later,
ie wrt gen ai models which give out their thinking.

Have updated append_response to expect both the key and the value
wrt the latestResponse object, which it will be manipualted.

Previously it was always assumed that content is what will be got
and inturn appended.

Subject: [PATCH 010/266] SimpleChatTC: Avoid null content, Fix oversight wrt
 finish_reason

I was wrongly checking for finish_reason to be non null, before
trying to extract the genai content/toolcalls, have fixed this
oversight with the new flow in progress.

I had added few debug logs to identify the above issue, need to
remove them later. Note: given that debug logs are disabled by
replacing the debug function during this program's initialisation,
which I had forgotten about, I didnt get the debug messages and
had to scratch my head a bit, before realising this and the other
issue ;)

Also either when I had originally implemented simplechat 1+ years
back, or later due to changes on the server end, the streaming
flow sends a initial null wrt the content, where it only sets the
role. This was not handled in my flow on the client side, so a
null was getting prepended to the chat messages/responses from the
server. This has been fixed now in the new generic flow.

Inturn switch the generic/toplevel handle response logic to use

Inturn add trimmedContent member to AssistantResponse class and

Subject: [PATCH 014/266] SimpleChatTC: twins wrt streamed response handling

As there could be failure wrt getting the response from the ai
server some where in between a long response spread over multiple
 parts, the logic uses the latestResponse to cache the response
as it is being received. However once the full response is got,
one needs to transfer it to a new instance of AssistantResponse
class, so that latestResponse can be cleared, while the new
instance can be used in other locations in the flow as needed.

Achieve the same now.

Subject: [PATCH 016/266] SimpleChatTC:tooljs: Trap console.log and store in
 new result key

The implementations of javascript and simple_calculator now use
provided helpers to trap console.log messages when they execute
the code / expression provided by GenAi and inturn store the
captured log messages in the newly added result key in tc_switch

This should help trap the output generated by the provided code
or expression as the case maybe and inturn return the same to the
GenAi, for its further processing.

as a object.

Inturn the text generated by the tool/func is captured and put
into the user input entry text box, with tool_response tag around
it.

Subject: [PATCH 018/266] SimpleChatTC: Cleanup initial/1st go toolcall flow

As output generated by any tool/function call is currently placed
into the TextArea provided for End user (for their queries), bcas
the GenAi (engine/LLM) may be expecting the tool response to be
sent as a user role data with tool_response tag surrounding the
results from the tool call. So also now at the end of submit btn
click handling, the end user input text area is not cleared, if
there was a tool call handled, for above reasons.

Also given that running a simple arithmatic expression in itself
doesnt generate any output, so wrap them in a console.log, to
help capture the result using the console.log trapping flow that
is already setup.

Should hopeful ensure that the GenAi/LLM will generate appropriate
code/expression as the argument to pass to these tool calls, to
some extent.

Move tool calling logic into tools module.

Try trap async promise failures by awaiting results of tool calling
and putting full thing in an outer try catch. Have forgotten the

So that when tool handler writes the result to the tc_switch, it
can make use of the same, to write to the right location.

NOTE: This also fixes the issue with I forgetting to rename the
key in js_run wrt writing of result.

+#### Mapping tool calls and responses to normal assistant - user chat flow
+
+Instead of maintaining tool_call request and resultant response in logically seperate parallel
+channel used for requesting tool_calls by the assistant and the resulstant tool role response,
+the SimpleChatTC pushes it into the normal assistant - user chat flow itself, by including the
+tool call and response as a pair of tagged request with details in the assistant block and inturn
+tagged response in the subsequent user block.
+
+This allows the GenAi/LLM to be aware of the tool calls it made as well as the responses it got,
+so that it can incorporate the results of the same in the subsequent chat / interactions.
+
+NOTE: This flow tested to be ok enough with Gemma-3N-E4B-it-Q8_0 LLM ai model for now.
+
+TODO: Need to think later, whether to continue this simple flow, or atleast use tool role wrt
+the tool call responses or even go further and have the logically seperate tool_call request
+structures also.

Subject: [PATCH 028/266] SimpleChatTC: Let user trigger tool call, instead of
 automatic

Instead of automatically calling any requested tool by the GenAi
/ llm, that is from the tail end of the handle user submit btn
click,

Now if the GenAi/LLM has requested any tool to be called, then
enable the Tool Run related UI elements and fill them with the
tool name and tool args.

In turn the user can verify if they are ok with the tool being
called and the arguments being passed to it. Rather they can
even fix any errors in the tool usage like the arithmatic expr
to calculate that is being passed to simple_calculator or the
javascript code being passed to run_javascript_function_code

If user is ok with the tool call being requested, then trigger
the same.

The results if any will be automatically placed into the user
query text area.

User can cross verify if they are ok with the result and or
modify it suitabley if required and inturn submit the same to
the GenAi/LLM.

same.

Also ensure to add a newline at end of console.log messages

Subject: [PATCH 036/266] SimpleChatTC: Actual tool call implementations
 simplified

These no longer need to worry about

* setting up the console.log related redirection to capture
  the generated outputs, nor about
* setting up a dynamic function for executing the needed
  tool call related code

The web worker setup to help run tool calls in a relatively
isolated environment independent of the main browser env,
takes care of these.

One needs to only worry about getting the handle to the
web worker to use and inturn pass the need code wrt the
tool call to it.

tools manager/module

* pass the web worker to the tool call providers, for them to use

* dont wait for the result from the tool call, as it will be got
  later asynchronously through a message

* allow users of the tools manager to register a call back, which
  will be called when ever a message is got from the web worker
  containing response wrt previously requested tool call execution.

simplechat

* decouple toolcall response handling and toolcall requesting logic

* setup a timeout to take back control if tool call takes up too
  much time. Inturn help alert the ai model, that the tool call
  took up too much time and so was aborted, by placing a approriate
  tagged tool response into user query area.

* register a call back that will be called when response is got
  asynchronously wrt anye requested tool calls.
  In turn take care of updating the user query area with response
  got wrt the tool call, along with tool response tag around it.

Subject: [PATCH 038/266] SimpleChatTC: Web worker flow initial go cleanup

Had forgotten to specify type as module wrt web worker, in order
to allow it to import the toolsconsole module.

Had forgotten to maintain the id of the timeout handler, which is
needed to clear/stop the timeout handler from triggering, if tool
call response is got well in time.

As I am currently reverting the console redirection at end of
handling a tool call code in the web worker message handler, I
need to setup the redirection each time. Also I had forgotten
to clear the console.log capture data space, before a new tool
call code is executed, this is also fixed by this change.

TODO: Need to abort the tool call code execution in the web worker
if possible in future, if the client / browser side times out
waiting for tool call response, ie if the tool call code is taking
up too much time.

Subject: [PATCH 039/266] SimpleChatTC: Increase the sliding window context to
 Last4 QA

As the tool calling, if enabled, will need access to last few
user query and ai assistant responses (which will also include
in them the tool call requests and the corresponding results),
so that the model can build answers based on its tool call reqs
and got responses, and also given that most of the models these
days have sufficiently large context windows, so the sliding
window context implemented by SimpleChat logic has been increased
by default to include last 4 query and their responses roughlty.

Use the equivalent update_stream directly added to ChatMessageEx.

update_stream is also more generic to some extent and also directly

Subject: [PATCH 054/266] SimpleChatTC:Propogate toolcall id through tool call
 chain

Use HTMLElement's dataset to maintain tool call id along with
the element which maintains the toolname.

Pass it along to the tools manager and inturn the actual tool
calls and through them to the web worker handling the tool call
related code and inturn returning it back as part of the obj
which is used to return the tool call result.

Embed the tool call id, function name and function result into
the content field of chat message in terms of a xml structure

Also make use of tool role to send back the tool call result.
Do note that currently the id, name and content are all embedded
into the content field of the tool role message sent to the
ai engine on the server.

NOTE: Use the user query entry area for showing tool call result
in the above mentioned xml form, as well as for user to enter
their own queries. Based on presence of the xml format data at
beginning the logic will treat it has a tool result and if not
then as a normal user query.

The css has been updated to help show tool results/msgs in a
lightyellow background

+Promise as well as users of promise (for now fetch) have been trapped wrt their then and catch flow,

As html can be malformed, xml ElementTree XMLParser cant handle
the same properly, so switch to the HtmlParser helper class that is
provided by python and try extend it.

Currently a minimal skeleton to just start it out, which captures
only the body contents.

 sent always

Add a new send headers common helper and use the same wrt the
overridden send_error as well as do_OPTIONS

This ensures that if there is any error during proxy opertions,
the send_error propogates to the fetch from any browser properly
without browser intercepting it with a CORS error

Make the previously relatively generic flow wrt apiRequestOptions
settings into a fully generic reusable by others flow.

Subject: [PATCH 113/266] SimpleChatTC:ShowObjPropsEdit:Any depth trapping of
 ui setup

Maintain the current property hierarchy to its root over recursive
calls.

Allow callers to specify the props to be trapped using the prop
hierarchy.

Pass the prop hierarchy to the fTrapper.

This should allow one to trap any prop wrt its editing ui setup,
irrespective of whether it is a prop of the main object passed,
or a member of a child prop of the main object passed or so ...

Update the setting up of ChatHistoryInCtxt and ApiEndPoint to follow
the new semantic/flow.

Subject: [PATCH 114/266] SimpleChatTC:ShowObjPropsEdit:Any depth trapping of
 ui setup - t2

Fix up the oversights wrt any depth trapping flow

Remember to start the propWithTree being checked/trapped with :
to indicate the root of the prop hierarchy and also use : as sep
between the elements of the props hierarchy tree

Also had forgotten about the goof up possible with using in in a
condition statement to check for array to contain a entry of interest
in JS, fixed it now.

Subject: [PATCH 125/266] SimpleChatTC:SimpleProxy: Cleanup domain filtering
 and general

Had confused between js and python wrt accessing dictionary
contents and its consequence on non existent key. Fixed it.

Use different error ids to distinguish between failure in common
urlreq and the specific urltext and urlraw helpers.

Instead of simple concatenating of tool call id, name and result
now use browser's dom logic to create the xml structure used for
now to store these within content field.

This should take care of transforming / escaping any xml special
chars in the result, so that extracting them later for putting
into different fields in the server handshake doesnt have any
problem.

Subject: [PATCH 135/266] SimpleChatTC:SimpleProxy: debug dumps to identify
 funny bing

bing raised a challenge for chrome triggered search requests after
few requests, which were spread few minutes apart, while still
seemingly allowing wget based search to continue (again spread
few minutes apart).

Added a simple helper to trace this, use --debug True to enable
same.

Subject: [PATCH 137/266] SimpleChatTC:Auto tool calling control to end user

Instead of enforcing always explicit user triggered tool calling,
now user is given the option whether to use explicit user triggered
tool calling or to use auto triggering after showing tool details
for a user specified amount of seconds.

NOTE: The current logic doesnt account for user clicking the buttons
before the autoclick triggers; need to cancel the auto clicks, if
user triggers before autoclick, ie in future.

 ### Tool Calling
 
-ALERT: The simple minded way in which this is implemented, it can be dangerous in the worst case,
-Always remember to verify all the tool calls requested and the responses generated manually to
-ensure everything is fine, during interaction with ai models with tools support.
+Given that browsers provide a implicit env for not only showing ui, but also running logic,
+simplechat client ui allows use of tool calling support provided by the newer ai models by
+end users of llama.cpp's server in a simple way without needing to worry about seperate mcp
+host / router, tools etal, for basic useful tools/functions like calculator, code execution
+(javascript in this case).
+
+Additionally if users want to work with web content as part of their ai chat session, Few
+functions related to web access which work with a included python based simple proxy server
+have been implemented.
+
+This can allow end users to use some basic yet useful tool calls to enhance their ai chat
+sessions to some extent. It also provides for a simple minded exploration of tool calling
+support in newer ai models and some fun along the way as well as occasional practical use
+like
+
+* verifying mathematical or logical statements/reasoning made by the ai model during chat
+sessions by getting it to also create and execute mathematical expressions or code to verify
+such stuff and so.
+
+* access content from internet and augment the ai model's context with additional data as
+needed to help generate better responses. this can also be used for
+  * generating the latest news summary by fetching from news aggregator sites and collating
+  organising and summarising the same
+  * searching for specific topics and summarising the results
+  * or so
+
+The tool calling feature has been tested with Gemma3N, Granite4 and GptOss (given that
+reasoning is currently unsupported by this client ui, it can mess with things)
+
+ALERT: The simple minded way in which this is implemented, it provides some minimal safety
+mechanism like running ai generated code in web workers and restricting web access to user
+specified whitelist and so, but it can still be dangerous in the worst case, So remember
+to verify all the tool calls requested and the responses generated manually to ensure
+everything is fine, during interaction with ai models with tools support.
 
 #### Builtin Tools

+
+##### directly in browser

 * run_javascript_function_code - which can be used to run some javascript code in the browser
   context.

-* fetch_web_url_text - fetch requested url through a proxy server
-  and also try strip the html respose of html tags and also head, script, style, header,footer,... blocks.

+Currently the ai generated code / expression is run through a simple minded eval inside a web worker
 mechanism. Use of WebWorker helps avoid exposing browser global scope to the generated code directly.
 However any shared web worker scope isnt isolated. Either way always remember to cross check the tool
 requests and generated responses when using tool calling.

Subject: [PATCH 144/266] SimpleChatTC:ToolCall:SearchWebText using UrlText

Initial go at implementing a web search tool call, which uses the
existing UrlText support of the bundled simpleproxy.py.

It allows user to control the search engine to use, by allowing
them to set the search engine url template.

The logic comes with search engine url template strings for
duckduckgo, brave, bing and google. With duckduckgo set by default.

Subject: [PATCH 147/266] SimpleChatTC:ToolCallResponseTimeout: Allow end user
 to control

Moved it into Me->tools, so that end user can modify the same as
required from the settings ui.

TODO: Currently, if tc response is got after a tool call timed out
and user submitted default timed out error response, the delayed
actual response when it is got may overwrite any new content in
user query box, this needs to be tackled.

Subject: [PATCH 154/266] SimpleChatTC:SimpleProxy: once in a bluemoon
 transformed bearer

instead of using the shared bearer token as is, hash it with
current year and use the hash.

keep /aum path out of auth check.

in future bearer token could be transformed more often, as well as
with additional nounce/dynamic token from server got during initial
/aum handshake as also running counter and so ...

NOTE: All these circus not good enough, given that currently the
simpleproxy.py handshakes work over http. However these skeletons
put in place, for future, if needed.

TODO: There is a once in a bluemoon race when the year transitions
between client generating the request and server handling the req.
But other wise year transitions dont matter bcas client always
creates fresh token, and server checks for year change to genrate
fresh token if required.

Subject: [PATCH 155/266] SimpleChatTC:ToolTemp and ChatShow

Add a new role ToolTemp, which is used to maintain any tool call
response on the client ui side, without submitting it to the server
ie till user or auto submit triggers the submitting of that tool
call response.

When ever a tool call response is got, create a ToolTemp role based
message in the corresponding chat session. And dont directly update
the user query input area, rather leave it to the updated simplechat
show and the new multichatui chat_show helper and inturn whether the
current chat session active in ui is same as the one for which the
tool call response has been recieved.

TODO: Currently the response message is added to the current
active chat session, but this needs to be changed by tracking
chatId/session through the full tool call cycle and then adding
the tool call response in the related chat session, and inturn
updating or not the ui based on whether that chat session is
still the active chat session in ui or not, given that tool call
gets handled in a asynchronous way.

Now when that tool call response is submitted, promote the equiv
tool temp role based message that should be in the session's chat
history as the last message into becoming a normal tool response
message.

SimpleChat.show has been updated to take care of showing any
ToolTemp role message in the user query input area.

A newer chat_show helper added to MultiChatUI, that takes care of
calling SimpleChat.show, provided the chat_show is being requested
for the currently active in ui, chat session. As well as to take
care of passing both the ChatDiv and elInUser. Converts users of
SimpleChat.show to use MultiChatUI.chat_show

Subject: [PATCH 156/266] SimpleChatTC:ToolCallErrPath:ToolTemp and
 MultiChatUIChatShow

Update the immidiate tool call triggering failure and tool call
response timeout paths to use the new ToolTemp and MultiChatUI
based chat show logics.

Actual tool call itself generating errors, is already handled
in the previous commit changes.

Subject: [PATCH 161/266] SimpleChatTC:Reasoning: Cleanup the initial go

Rather simplify and make the content_equiv provide a relatively
simple and neat representation of the reasoning with content and
toolcall as the cases may be.

Also remove the partial new para that I had introduced in the
initial go for reasoning.

Subject: [PATCH 165/266] SimpleChatTC:MultiChatUI:ChatShow cleanup of Initial
 skeleton

Fix up the initial skeleton / logic as needed.

Remember that we are working with potentially a subset of chat
messages from the session, given the sliding window logic of
context managing on client ui side, so fix up the logic to use
the right subset of messages array and not the global xchat
when deciding whether a message is the last or last but one,
which need special handling wrt Assistant (with toolcall) and
Tool (ie response) messages.

Moving tool call ui setup as well as tool call response got ui
setup into ChatShow of MultiChatUI ensures that switching between
chat sessions handle the ui wrt tool call triggering ui and tool
call response submission related ui as needed properly.

Rather even loading a previously auto saved chat session if it had
tool call or tool call response to be handled, the chat ui will be
setup as needed to continue that session properly.

Subject: [PATCH 169/266] SimpleChatTC:ShowMessage: containers, role, contents

Seperate out the message ui block into a container containing
a role block and contents container block.

This will allow themeing of these seperately, if required.
As part of same, currently the role has been put to the side
of the message with vertical text flow.

Subject: [PATCH 173/266] SimpleChatTC:UICleanup: WordBreaks, Print avoid side
 vertical

Define rules to ensure that chat message contents wrap so as to
avoid overflowing beyond the size of the screen being viewed.

The style used for chat message role to be placed with vertical
oriented text adjacent to the actual message content on the side
seems to be creating issue with blank pages in some browsers,
so avoid that styling when one is printing.

So mention that may be ai can send complex objects in stringified
form. Rather once type of value is set to string, ai should normally
do it, but no harm is hinting.

Subject: [PATCH 179/266] SimpleChatTC:DataStore:Eagerness to Wrong JSON
 conversions

In the eagerness of initial skeleton, had forgotten that the
root/generic tool call router takes care of parsing the json string
into a object, before calling the tool call, so no need to try
parse again. Fixed the same.

Hadnt converted the object based response from data store related
calls in the db web worker, into json string before passing to the
generic tool response callback, fixed the same.

- Rather the though of making the ChatMsgEx.createAllInOne handle
string or object set aside for now, to keep things simple and
consistant to the greatest extent possible across different flows.

And good news - flow is working atleast for the overall happy path
Need to check what corner cases are lurking like calling set on
same key more than once, seemed to have some flow oddity, which I
need to check later.

Also maybe change the field name to value from data in the response
to get, to match the field name convention of set. GPT-OSS is fine
with it. But worst case micro / nano / pico models may trip up, in
worst case, so better to keep things consistent.

Subject: [PATCH 189/266] SimpleChatTC:Seperate out actual nw handshake -
 initial go

move the actual chat handshake with ai server into a seperate code
to an extent.

also initial anchor to trap handshake http error responses

Rather come to think of it, its better to move this into SimpleChat
class.

Use finally to ensure any needed cleanup for handle_user_submit
occurs within itself.

Subject: [PATCH 198/266] SimpleChatTC:Pdf2Text: cleanup initial go

Make the description bit more explicit with it supporting local
file paths as part of the url scheme, as the tested ai model was
cribbing about not supporting file url scheme. Need to check if
this new description will make things better.

Convert the text to bytes for writing to the http pipe.

Ensure CORS is kept happy by passing AccessControlAllowOrigin in
header.

Subject: [PATCH 203/266] SimpleChatTC:TC Result truncating only if needed

As I was seeing the truncated message even for stripped plain text
web acces, relooking at that initial go at truncating, revealed
a oversight, which had the truncation logic trigger anytime the
iResultMaxDataLength was greater than 0, irrespective of whether
the actual result was smaller than the allowed limit or not,
thus adding that truncated message to end of result unnecessarily.
Have fixed that oversight

Also recent any number of args based simpleprox handshake helper
in toolweb seems to be working (atleast for the existing single
arg based calls).

Subject: [PATCH 209/266] SimpleChatTC:SimpleProxy: Use urlvalidator

Add --allowed.schemes config entry as a needed config.

Setup the url validator.

Use this wrt urltext, urlraw and pdf2text

This allows user to control whether local file access is enabled
or not. By default in the sample simpleproxy.json config file
local file access is allowed.

Subject: [PATCH 215/266] SimpleChatTC:SimpleProxy: getting local / web file
 module ++

Added logic to help get a file from either the local file system
or from the web, based on the url specified.

Update pdfmagic module to use the same, so that it can support
both local as well as web based pdf.

Bring in the debug module, which I had forgotten to commit, after
moving debug helper code from simpleproxy.py to the debug module

Subject: [PATCH 223/266] SimpleChatTC: ToolCalling enabled, Sliding window
 adjust

Chances are for ai models which dont support tool calling, things
will be such that the tool calls meta data shared will be silently
ignored without much issue.

So enabling tool calling feature by default, so that in case one
is using a ai model with tool calling the feature is readily
available for use.

Revert SlidingWindow ChatHistory in Context from last 10 to last 5
(2 more then origianl, given more context support in todays models)
by default, given that now tool handshakes go through the tools
related side channel in the http handshake and arent morphed into
normal user-assistant channel of the handshake.

Subject: [PATCH 227/266] SimpleChatTC:WebTools: urltext-tag-drops python side
 - skel

Rename search-drops to urltext-tag-drops, to indicate its more
generic semantic. Rather search drops specified in UI by user
will be mapped to urltext-tag-drops header entry of a urltext
web fetch request.

Implement a crude urltext-tag-drops logic in TextHtmlParser.
If there is any mismatch with opening and closing tags in the
html being parsed and inturn wrt the type of tag being targetted
for dropping, things can mess up.

Subject: [PATCH 228/266] SimpleChatTC:WebTools:UrlText:HtmlParser: tag drops -
 refine

Update the initial skeleton wrt the tag drops logic

* had forgotten to convert object to json string at the client end
* had confused between js and python and tried accessing the dict
  elements using . notation rather than [] notation in python.
* if the id filtered tag to be dropped is found, from then on
  track all other tags of the same type (independent of id),
  so that start and end tags can be matched. bcas end tag call
  wont have attribute, so all other tags of same type need to
  be tracked, for proper winding and unwinding to try find
  matching end tag
* remember to reset the tracked drop tag type to None once matching
  end tag at same depth is found. should avoid some unnecessary
  unwinding.
* set/fix the type wrt tagDrops explicitly to needed depth and
  ensure the dummy one and any explicitly got one is of right type.

Tested with duckduckgo search engine and now the div based unneeded
header is avoided in returned search result.

Subject: [PATCH 232/266] SimpleChatTC:FetchPdfAsText: Renamed function call

Some ai's dont seem to be prefering to use this direct helper
provided for fetching pdf as text, on its own. Instead ai (gptoss)
seems to be keen on fetching raw pdf and extract text etal, so now
renaming the function call to try and make its semantic more
readily obivious hopefully.

It sometimes (not always) seem to assum fetch_web_url_text, can
convert pdf to text and return it. Maybe I need to place the
specific fetch pdf as text before the generic fetch web url text
and so...

With the rename, the pdf specific fetch seems to be getting used
more.

Have main classes defined independent of and away from runtime flow

Move out the entry point including runtime instantiation of the
core Me class (which inturn brings other class instances as neede)
into its own main.js file.

With this one should be able to import simplechat.js into other
files, where one might need the SimpleChat or MultiChat or Me class
definitions.

Subject: [PATCH 236/266] SimpleChatTC:MeInTools: WebWorkers in Me

Given that Me is now passed to the tools logic during setup, have
the web worker handles in Me itself, instead of in tool related
modules.

Move setup of web worker related main thread callbacks, as well as
posting messages directly to these main thread callbacks, into Me.

Subject: [PATCH 237/266] SimpleChatTC:Rather bring in Tools Class

So that all tools related management logic sits in tools module
itself, but is accessible from Me by having a instance of Tools.

The Workers moved into Tools class.

The tc_switch moved into Tools class.

The setup_workers, init, meta and tool_call moved into Tools class.

Subject: [PATCH 238/266] SimpleChatTC:ToolsManager: Instantiate in Me and Use

Rename Tools to ToolsManager to convey its semantic better.

Move setup of workers onmessage callback as well as directly passing
result to these callbacks into ToolsManager.

Now that Workers have been moved into ToolsManager, and ToolsManager
has been instantiated as a member of Me, use the same in place of
prev workers of Me.

Subject: [PATCH 239/266] SimpleChatTC:ToolsManager: Cleanup inc delayed direct
 posting

Me.tools.toolNames is now directly updated by init of ToolsManager

The two then in the old tools.init was also unneeded then also as
both could have been merged into a single then, even then. However
with the new flow, the 1st then is no longer required.

Also now the direct calling of onmessage handler on the main thread
side wrt immidiate result from tool call is delayed for a cycling
through the events loop, by using a setTimeout.

No longer expose the tools module throught documents, given that
the tools module mainly contains ToolsManager, whose only instance
is available through the global gMe.

Move the devel related exposing throught document object into a
function of its own.

Subject: [PATCH 240/266] SimpleChatTC:TrackToolCalls:helps ignor delayed
 response, if reqd

Add a pending object which maintains the pending toolcallid wrt
each chat session, when ever a tool call is made.

In turn when ever a tool call response is got cross check if its
toolcallid matches that in the pending list. If so accept the
tool call response and remove from pending list. If not just
ignore the response.

NOTE: The current implementation supports only 1 pending tool call
at any time.

NOTE: Had to change from a anonymous to arrow function so as to
be able to get access to the ToolsManager instance (this) from
within the function. ie make use of lexical binding semantic of
arrow functions.

instead of the prefixing of tag heirarchy retain the xml structure
while parallely allowing unwanted tags and their contents to be
dropped.

Subject: [PATCH 249/266] SimpleChatTC:Rename fetch_web_url_text to
 fetch_html_text

To make it easier for the ai model to understand that this works
mainly for html pages and not say xml or pdf or so. For those
one needs to use other explict tool calls provided like fetchpdftext
or fetchxmltext or so

The server service path renamed from urltext to htmltext.

SearchWebText also updated to use htmltext now

Subject: [PATCH 253/266] SimpleChatTC:PdfText: Numbering T1 - Diff Scheme
 needed

This simple scheme doesnt work. Rather the pdf outline seems
to follow below logic

If a child list is found when processing the current list, dont
increment the numbering.

 ChatMessageEx

NSChatMessage implements the undefined based flow and provides
helpers to check if any of the field like content or reasoning
or tool_calls is available in the chat message or not.

It also provides helpers to get the corresponding fields.

ChatMessageEx updated to make use of NSChatMessage.

Subject: [PATCH 258/266] SimpleChatTC:NSChatMessage: Update SimpleChat to use
 same

Remove the load from disk support that was previously retained
wrt the old on-disk-storage format for the chat session messages.

Make a note to allow non ai server handshake roles to be maintained
wrt NSChatMessage. Add helper to cross check if a message belongs
to such temp roles or not.

Update SimpleChat class to make use of the new NSChatMessage based
needed flow.

Subject: [PATCH 260/266] SimpleChatTC:NSChatMessage with tool response/result
 fields

Add a new static helper to create a ChatMessageEx for a given
tool response data.

Use the same when storing tool response in the chat session msgs
list.

This inturn avoids the need for creating a xml string with all
the fields corresponding to tool response. So also no need to
extract the individiual tool response fields from the all-in-one
xml string and populate the tool response fields in the network
structure equivalent ns data structure, when recent_chat_ns is
called.

Subject: [PATCH 261/266] SimpleChatTC:NSChatMessage:ToolResponse show handling

Given that the user query box no longer includes the special xml
string wrt tool response data (TOOL.TEMP ROLE), so now instead set
a special attribute to indicate that user query/input box is
maintaining a tool response.

For regular Tool responses in the chat session, now show the tool
call id and tool name before the tool response data (ie content
field).

Subject: [PATCH 265/266] SimpleChatTC:NSChatMessage:ToolResult User Input
 Background color

Use css conditional attribute styling to change background color
of the user input textarea to match the tool role message block
color, when the user input textarea is in the TOOL.TEMP mode

With this user can know that the user input area is currently
showing and accepting tool result data for submission.

Subject: [PATCH 266/266] SimpleChatTC:Alert end user in case emtpy message to
 ai

Currently the logic doesnt allow user to send a empty message to
ai, during their term. Previously this path wasnt directly alerting
the end user. Now it informs the end user using placeholder property
so they can see the alert, while also ensuring that once user enters
something, the alert wont interfere.

The logic takes care of saving any original placeholder, so that
the same is restored, when user switches sessions.
