Search - "incorrect parsing"

I am much too tired to go into details, probably because I left the office at 11:15pm, but I finally finished a feature. It doesn't even sound like a particularly large or complicated feature. It sounds like a simple, 1-2 day feature until you look at it closely.
It took me an entire fucking week. and all the while I was coaching a junior dev who had just picked up Rails and was building something very similar.
It's the model, controller, and UI for creating a parent object along with 0-n child objects, with default children suggestions, a fancy ui including the ability to dynamically add/remove children via buttons. and have the entire happy family save nicely and atomically on the backend. Plus a detailed-but-simple listing for non-technicals including some absolutely nontrivial css acrobatics.
After getting about 90% of everything built and working and beautiful, I learned that Rails does quite a bit of this for you, through `accepts_nested_params_for :collection`. But that requires very specific form input namespacing, and building that out correctly is flipping difficult. It's not like I could find good examples anywhere, either. I looked for hours. I finally found a rails tutorial vide linked from a comment on a SO answer from five years ago, and mashed its oversimplified and dated examples with the newer documentation, and worked around the issues that of course arose from that disasterous paring.
like.
I needed to store a template of the child object markup somewhere, yeah? The video had me trying to store all of the markup in a `data-fields=" "` attrib. wth? I tried storing it as a string and injecting it into javascript, but that didn't work either. parsing errors! yay! good job, you two.
So I ended up storing the markup (rendered from a rails partial) in an html comment of all things, and pulling the markup out of the comment and gsubbing its IDs on document load. This has the annoying effect of preventing me from using html comments in that partial (not that i really use them anyway, but.)
Just.
Every step of the way on building this was another mountain climb.
* singular vs plural naming and routing, and named routes. and dealing with issues arising from existing incorrect pluralization.
* reverse polymorphic relation (child -> x parent)
* The testing suite is incompatible with the new rails6. There is no fix. None. I checked. Nope. Not happening.
* Rails6 randomly and constantly crashes and/or caches random things (including arbitrary code changes) in development mode (and only development mode) when working with multiple databases.
* nested form builders
* styling a fucking checkbox
* Making that checkbox (rather, its label and container div) into a sexy animated slider
* passing data and locals to and between partials
* misleading documentation
* building the partials to be self-contained and reusable
* coercing form builders into namespacing nested html inputs the way Rails expects
* input namespacing redux, now with nested form builders too!
* Figuring out how to generate markup for an empty child when I'm no longer rendering the children myself
* Figuring out where the fuck to put the blank child template markup so it's accessible, has the right namespacing, and is not submitted with everything else
* Figuring out how the fuck to read an html comment with JS
* nested strong params
* nested strong params
* nested fucking strong params
* caching parsed children's data on parent when the whole thing is bloody atomic.
* Converting datetimes from/to milliseconds on save/load
* CSS and bootstrap collisions
* CSS and bootstrap stupidity
* Reinventing the entire multi-child / nested params / atomic creating/updating/deleting feature on my own before discovering Rails can do that for you.
Just.
I am so glad it's working.
I don't even feel relieved. I just feel exhausted.
But it's done.
finally.
and it's done well. It's all self-contained and reusable, it's easy to read, has separate styling and reusable partials, etc. It's a two line copy/paste drop-in for any other model that needs it. Two lines and it just works, and even tells you if you screwed up.
I'm incredibly proud of everything that went into this.
But mostly I'm just incredibly tired.
Time for some well-deserved sleep.7 -
Had a bad day at work :( They gave me this code for some obscure streaming job and asked me to complete it. Only after 3 days did I realize that the LLD given to me was incorrect as the data model was updated. Another 2 more days, I was able to debug the code and run it successfully— I was able to parse the tables and generate the required frame but not able to stream it back to the output topic as per the LLD. That’s where I needed help but none of my emails/messages were replied to. The main guy who is pretty technical scheduled a code review session with me— I expected that I would run the code and he would spot it something I might’ve missed and why my streaming function isn’t working. Instead, what happened was that he grilled me on each and every line of the code (which had some obscure tables queried) and then got super mad at me saying “Why are we having this code review session if your code is not complete?”. I’m like bruh, you asked for it, and yes, the main parsing logic is done and I’m just having this issue in the last part. And he’s like “Why didn’t you tell me earlier?”. Wtf?! I left at least 5 emails and a dozen messages. He’s like this has to go live on Monday, and I’m like Ok, I’ll work in the weekend. And he’s like “Don’t tell me all these things! You’re not doing me a favor by working on weekends! How am I to ask my colleagues to connect with you separately on Saturday/Sunday? You should have done the on the weekdays itself. What were you doing this whole week?”. Bruh, I was running the code multiple times and debugging it using print statements. All while you were ignoring my attempts to reach out to you. SMH 🤦♂️ I can go on and on about this whole saga.4

I know it a strange thing to ask but I need help with English grammar ( I am not a English native)
I am doing an assignment on context free grammar program.
What the program need to do it "Produce a grammar tree based on the rule"
For example a sentence "Jame sat.", It will need to produce a grammar tree like this.
S
_____|___
NP VP
| |
N V
| |
holmes sat
The only thing I need to do it give a grammar rule to the program like this
S -> NP VP
NP -> N | Det N
VP -> V | NP
What the above rule said is that the sentence is composed of Noun Phrase and Verb Phrase and Noun Phrase is either is a Noun or a determiner and Noun.
Now here is the meat of the question.
I am having trouble parsing a grammar tree for this sentence "She never said a word until we were at the door here"
I have provided my grammar rule below. I think I forget to add some grammar rule or some of my grammar rule are incorrect. I am not a native English speaker so I am having trouble on it.
The search engine have fail me (I have look up various grammar tree) so I am asking for help on devrant. Grammar nazi are warmly welcome :)
S -> NP VP | S Conj VP | S Conj S
NP -> N | Det NP | N PP | Adj N | Det Adj N | Det N
PP | Det NOM | Det N PP
VP -> V | V NP | V NP PP | V PP | V NP PP Adv
VP -> Adv V NP | VP PP | VP AVP | V PP PP | V
ADJP
PP -> P NP
AVP -> Adv | Adv Adj | Adv AVP
NOM -> Adj Adj N | Adj N | Adj NP
ADJP -> Adj | Adj PP
**I am not sure about these two clause below**
VP -> V | Adv
NP -> Adj Adj N22
