purple letters

Hello,

 

I have a quick question on the code highlighting.  I often use a single character as an alias for tables in joins.  I have noticed that some letters are colored purple while others are black.  Is there a reason for this?  I have attached an image showing what I mean.  The image was taken from version 2.0-rc2.

 

Thanks,
Brandon

Some weirdness from codemirror I suspect, but I have no idea what exactly. I think one of the other EDB guys looked at it's parser once, and may be able to suggest.

Hi,

The characters which are in purple colour are are valid SQL keywords hence highlighted by CodeMirror :-)

Thanks Dave and Murtuza,

 

I didn’t realize that they were SQL keywords.  Thanks for taking the time to answer my question. 

 

I am really liking the improvements to pgAdmin 4.  Keep up the good work!

For my part, when I designed my programming language, I intentionally did not 
use single-letter names for any keywords or reserved words or system-defined 
entities etc, and all built-ins were either 2+ letters or were symbols.  As a 
result, single-letter names are available/reserved for end users as barewords to 
name their own (presumably narrow-lexical-scope) stuff, without having to guess 
which letters they may use. -- Darren Duncan
