Answered 2021-Mar-30 at 12:26As Deceze has commented, if the data is corrupted at source there is no guarantee that you can undo the corruption. However, using the data you provided we can make some progress.
Firstly, the vast majority of the strings in your list can be fixed by encoding as latin-1 and then decoding as UTF-8.
QUESTION
This ANTLR4 parser grammar errors a 'no viable alternative' error when I try to parse an input. The only rules I know of that matches the part of the input with the error are the rules 'retblock_expr' and 'block_expr'. I have put 'retblock_expr' infront of 'block_expr' and put 'non_assign_expr' infront of 'retblock_expr' but it still throws the error.
input:
print(do { return a[3] })
full error:
line 1:11 no viable alternative at input '(do { return'
parser grammar:
...ANSWER
Answered 2021-Mar-27 at 14:13Your PRINT
token can only be matched by the blk_expr
rule through this path:
There is no path for retblock_expr
to recognize anything that begins with the PRINT
token.
As a result, it will not matter which order you have elk_expr
or retblock_expr
.
There is no parser rule in your grammar that will match a PRINT
token followed by a LPR
token. a block_expr
is matched by the program
rule, and it only matches (ignoring wsp) block_expr
or retblock_expr
. Neither of these have alternatives that begin with an LPR
token, so ANTLR can't match that token.
print(...)
would normally be matched as a function call expression that accepts 0 or more comma-separated parameters. You have no sure rule/alternative defined. (I'd guess that it should be an alternative on either retblock_expr
or block_expr
That's the immediate cause of this error. ANTLR really does not have any rule/alternative that can accept a LPR
token in this position.

When I run my grammar (lexer and parser) in powershell, it produces these errors:
...ANSWER
Answered 2021-Mar-23 at 10:50Both global
and a
are listed in your grammer under kwr
rule.
kwr
is mentioned in the inl
rule which isn't used anywhere. So your parser don't know how to deal with inl
and don't know what to do with two inl
chained together (global a
)
QUESTION

As I run the application,the chromewebdriver opens, as soon as it opens a Notification/message pops up on the website which says to "Accept Cookies", I accept it programmatically however my program stops it execution soon after.

QUESTION
Still very new at web programming and I can't seem to figure out why my content keeps coming out of my div. When i zoom in the button and headers flow outside of its container here you can see my code on codepen:
https://codepen.io/roger-matadeen/pen/PozWVVE
here my html
ANSWER
Answered 2020-Oct-24 at 22:23First of all you need to only insert the content from inside the in codepen
HTML
section.
Your issue occurs because you set height: 70vh
to .hero
.
So no matter how the content inside .hero
is big relative to the viewport height (vh
) .hero
is always 70% height of its height.
To fix this issue you may want to set height: auto
for example.

I am trying to hide the input value of each individual input when clicked
My javascript is working fine but only targets the individual ID listed. I am looking for a more refined method that selects only the clicked input without having to repeat that same block of code 5 times targeting each different ID

My solution is always try to clipr::write_clip(results[605])
and paste into whatever place. Then you can see the code of this string also can paste into google to search it :)
After you can do this results <- results[results != '\U00A0']

...ANSWER
Answered 2020-Mar-25 at 07:46Airflow recommends to state a fixed startstart_date
for your DAG. start_date is mainly for the purpose to specify when do you want your DAG to start running for the very first time. schedule_interval
will be the most relevant one after the start_date did its purpose or (if you do not need to backfill or reset your dag).
