Re: Folders for scripts and backups

P.S. Perhaps even better, and simpler, remember the last setting on a database-by-database basis, rather than taking it from the last use of Rel.

Folders for scripts and backups

When I want to load a script or make a backup, Rel initially assumes "My documents" as the target folder but then uses the one most recently used. That works fine for me on the odd occasions when successive executions of Rel are with the same database. However, I'm much more likely to be u...

Re: Rel interface: Having to scroll to the bottom to add a tuple

I was pleased with the way my request in 2017 was dealt with, but when I asked for it I did so in connection with "edit". Over the past seven years I've frequently had to use ctrl+home when simply displaying the contents of a relvar (base or virtual) with no intention to add, delete, or up...

Re: Spurious sytax error with INSERT

Thank you. I like your suggested bypass because since I posted this problem I've been surrounding the code with begin/end for other reasons. My own bypass had been to use direct assignment: x := (extend TABLE_DEE <etc.>) union x;

insert sometimes doesn't insert anything

This might have to be just a heads up to begin with. I can't give a specific example at this time because the examples where this bug is hitting me are too complex. Sometimes, when I give an INSERT command, with a complex expression as source and a target of existing high cardinality, the operation ...

Spurious sytax error with INSERT

Try this: var x base relation{z char} key{z}; insert x extend TABLE_DEE : {z := '//'}; I get ERROR: Encountered "insert" at line 1, column 1. Was expecting one of: "BEGIN" ... "TCLOSE" ... <TUPLE> ... "WITH" ... <TUPLE> ... I have used a bypass of this kind so...

Re: RENAME in V3.013 incompatible with previous versions

Thanks for the confirmation.

I fully agree with the change. On reflection, I feel rather ashamed of exploiting what I would regard as a bug in previous versions!

RENAME in V3.013 incompatible with previous versions

This might not be a bug, but rather a change resulting from a bug fix, but I'm asking the question under this rubric for want of a more appropriate one. In all versions up to V3.012 the following expression was legal: rel{tup{x1 1}} rename {suffix '1' as '', x as y} resulting in rel{tup{y 1}} In V3....

Re: WITH not available in a WHERE condition

Yes, I did later think of using parens, but our grammar does specify WHERE <bool exp>.

WITH not available in a WHERE condition

Rel allows the use of WITH in a <bool exp> but not when the <bool exp> is given as a WHERE condition.

I tested this with

Code: Select all

WITH (x := TRUE) : x
and

Code: Select all

r WHERE WITH (x := TRUE) : x
.

Re: Scroll bar disappears in Rel mode

Actually I don't have that setting. And now I notice that the problem arises only when I use Edit, and it stays in effect when I cease editing and just use Show.

Scroll bar disappears in Rel mode

In "Rel" mode, to keep the scroll bar available I have to keep the window very wide, usually with a large amount of unused space, occupying most of my screen. This is annoying when I need to look at that window at the same time as other windows. The same problem does not arise in command m...

Old database treated as a new one

Every time I open a certain database that I've had for several years, I get the "Welcome" thing in Rel and no history in command line mode. I found that the system's history relvar didn't exist, so I created it, using text from another database's backup file, but that didn't help. How can ...

Copied text stays in clipboard when it shouldn't

Here's a strange one that has only emerged with improved copy-and-paste in v3.011. I copy something from Rel 's output pane and paste it somewhere, no problem. Then, with Rel still running I go to another (non- Rel )window and use ctrl+c or edit/copy from there. When I then try to paste that somewhe...
