Fixes#577
With the previous implementation we weren't escaping the regex meta
characters . And in certain cases glob had a different meaning than
regex.
For e.g , the below shows a glob pattern with its regex equivalent
- `[][]` translates to `[\]\[]`
- `[^][]` translates to `[^\]\[]`
Closes#578
I have added support for like function with escape i.e like(X,Y,Z) .
There is good opportunity to refactor/cleanup the like operations which
can be done in another PR, as I wanted to keep the changes small .
Closes#568
Fixes#552
In our construct regex function, we were not escaping the required
characters properly which was causing the failure.
Limbo output with this branch
```
limbo> select like('\%A', '\A');
1
limbo> select like('A$%', 'A$');
1
limbo> select like('%a.a', 'aaaa');
0
```
Closes#553
Implements [json_array](https://sqlite.org/json1.html#jarray).
As a side quest, this PR also fixes an issue with the `CHAR` function
which didn't work properly if the parameters were non-leaf AST nodes.
The PR is quite big, because as I mentioned in https://github.com/tursod
atabase/limbo/issues/127#issuecomment-2541307979 we had to modify
`OwnedValue::Text` to support a `subtype` parameter, which is what
SQLite does.
Closes#504
This adds an interrupt() method to Statement that allows apps to
interrupt a running statement. Please note that this is different from
`sqlite3_interrupt()` which interrupts all ongoing operations in a
database. Although we want to support that too, per statement interrupt
is much more useful to apps.
add [soundex](https://www.sqlite.org/lang_corefunc.html#soundex) scalar
function.
it seems that sqlite did not enable `soundex()` function by default
unless build it with `SQLITE_SOUNDEX`, while the sqlite in the ci
workflow did not enable it. this pr skipped the test over `soundex()`
temporarily in the `scalar-function.test` file.
Closes#453
Love the project, been following your blog posts for quite a while now.
I asked on Discord prior to submitting this, just because I didn't see a
specific issue for this feature... but if this PR is out of scope for
contributors, feel free to close it as I just had a good time hacking on
it.
This PR adds support for `BitAnd`, `BitOr`, and `BitNot` operators in
the vdbe, as well as unary expressions applied to aggregate functions;
which was needed in order to have `BitNot` support the same tests that
the other operators had.
*Also added unary negation of function calls, because since unary ops
were added, I figured adding support for the other existing unary
operator might be in scope, but lmk if not.
Let me know if there is any more tests or documentation to add/improve.
Closes#445
