Re: HTML font size in percentages

[J. Landman Gay via use-livecode]

Thanks for verifying it Paul, that's what I was thinking too. I'm looking at replacing the 
sizes via the style runs, I have a handler Mark Waddingham gave me/us on the list last year 
that I think I can modify.


But I'd be grateful to see yours too. No big hurry, I just need to get an idea of how to 
estimate my time at this point. Thank you very much.

could send code to you.

I did try setting the text size of the field, and all untagged chunks reflect the new size as 
expected (default field text is 20 points.) But there are exceptions embedded in the text that 
require superscripts and/or other sizes for chapter headings and other things. It looks like this:


TEXT HERE shift="-6">TEXT HERETEXT HERETEXT 
HERETEXT HERE, ETC ETC


The text is too long for a single field so I'm using Trevor's dataView (thank you so much 
Trevor!) The text sizes and superscripts are footnotes, references, and other supplementary 
info. They are scattered liberally around in the text.


Untagged text responds well to the field text size, which I can easily change in the dataView 
template. But the superscripts text size and offset, and other changes do not because they are 
specifically indicated with integers. If I could use percentages, then changing the field text 
size would proportionally change everything else. But percentages don't work in my tests.


I wish we could use CSS in LC fields, but it isn't supported. I can't use any type of browser 
because we need features that a browser doesn't support.




Are there varying sizes of text runs in the field? Could you set the textSize 
of the char 1 to -1 of the field to empty, then set it for the whole field? In 
one project I’ve implemented a feature similar to what Bob was talking about 
where I increment the textSize of the field by 1 point using Cmd/Cntl + or -.


This is a mobile app, so no keyboard is available. It's been in the app stores for about a year 
but our main complaint from users is that the text is too small on a phone. We'd like to fix 
that. The choice of font size would be a setting in user prefs and the text would accomodate 
that whenever the app runs.

The text has to be in a field for lots of reasons. Browsers and widgets are 
too limited.

Re: HTML font size in percentages

[Keith Clarke via use-livecode]

Hi Jaque,
A lot will depend:
1) Whether the changes in font size within the nested HTML tags have been set 
locally or ‘more properly' as relative to the root font size of the page in 
‘rem’, where 1 rem = 100% of the root font-size).
2) you want a global font-size adjustment or more granular.

If you can set CSS in the page (via the browser widget of by inserting text 
into the HTML), you could try experimenting with setting the body or other 
outermost element font-size to 5rem to see if that affected sizing throughout?

For example, if the page it has a body tag, you could insert the following 
style block into the HTML header tag.


body {font-size: 5rem;}

  
Best,
Keith

Re: HTML font size in percentages

[Devin Asay via use-livecode]

Jacque,

It sounds like the HTML tags are setting the size for runs of text in the 
field, so you can’t just set the textSize of the field?

Are there varying sizes of text runs in the field? Could you set the textSize 
of the char 1 to -1 of the field to empty, then set it for the whole field? In 
one project I’ve implemented a feature similar to what Bob was talking about 
where I increment the textSize of the field by 1 point using Cmd/Cntl + or -.

Re: Maximum length of mySQL request ?

[Bob Sneidar via use-livecode]

OIC you are searching arrays to obtain your IDs. That would make sense because 
arrays are memory based. SQL is file based as in sqLite, or else accessed 
(typically) over a network which would account for the speed disparity. Of 
course, to be fail, you will have to add the time to search the arrays, THEN 
the time to query your SQL database with the IDs to make that comparison equal.

Thank you for your reply.
I also did some google search before asking the question, but didn't
find anything, only about the size of the data returned by mySQL.

What makes you think of a possible design issue ?
The ids are auto-incremented every time a new entry is added to the
table, and the ids in the request are obtained by intersecting various
multi-dimensional arrays that make very complex searches very fast
(less than 1 sec, when it takes 5 to 10 sec with regular SQL queries).

Re: Maximum length of mySQL request ?

You can save some characters by the following:

SELECT ... FROM myTable WHERE id IN (5523,7831,162814,34895,...)

which is the same as using multiple OR equals in your example.

If you need to break this up further, you can UNION the results of 
multiple queries, such as:


SELECT ... FROM myTable WHERE id IN (5523,7831,162814,34895,...) -- i.e. 
the first 100 or 1000 ids

UNION
SELECT ... FROM myTable WHERE id IN (100,512,,16545,...) -- the next 
100 or 1000 ids

UNION
... repeat as needed

Potential third party products

[Heather Laine via use-livecode]

Dear List Members,

We're conducting a general review of our vendor program and I was wondering if 
there are any lurking potential vendors on this list? Anyone with an addon for 
LiveCode they'd like to sell via our Extensions store? Or is there something 
you know of or find particularly useful, made by someone else, that you think 
would be a good candidate for a wider audience?

Probably best to reply to supp...@livecode.com  
rather than cluttering up the list.

Best Regards,
