BodgeMaster 47fd1f8970 test/nbt_read_write_helpers: Change unnecessarily long string to be just one above the allowed size 2022-09-26 23:53:53 +02:00
BodgeMaster 10b1d9fa0c lib/nbt: Start implementing NBT data types, make NBT::Helper::writeString() return an error instead of aborting the program
The former is finally some progress on getting NBT going,
though at this point it is all unvalidated work.
For all I know it might cause your computer to burst into flames,
grow an arm and a leg and an eye, and attack you with a sword.
But probably, it won’t do that and instead start working after I
have debugged it so much that I wish I could attack my PC with a sword.

The latter is the implementation of a change I prepared in a previous commit
when i added ErrorOrVoid.

BodgeMaster 398321e415 test/nbt*: Replace NBT::helper with NBT::Helper
Yes, I forgot to run the test suite before committing.
This is why we need CI.

BodgeMaster ac12bcf865 Makefile: Finally get rid of this as we don't need it.
A makefile may be added back when we are preparing distribution but
it’s a long road until then.

BodgeMaster bb40f6553e tools/hexnet: comment sections out temporarily to get rid of compile errors
Doesn’t compile on Void x86_32 glibc. This will need to be investigated.
I just wanted to get rid of the errors while working on other issues.

Compile command:
ccache g++ -std=c++20 -Wall -Wextra src/tools/hexnet.cpp -I./include -Lbin/lib -l:cli.so -l:libsockpp.so -o bin/tools/hexnet

Never again will you need to manually convert binary data into an array!
This tool does it for you! Get it now for only $99! Limited availability!

To process data from stdin / a pipe, just pass `-` as the file name.

BodgeMaster a862590370 lib/nbt: Start implementing the NBT validator
In theory, this is it. It’s just missing the portion that deals with lists
and unit tests. Both will each likely require similar effort to this.

BodgeMaster acc19ae100 lib/nbt: Change behavior of totalTagSize to treat encounters of compounds and lists as errors
I stumbled over this when writing the unit test. Previously, it would return
an error code but explicitly mark it as not being an error. This was intended
behavior but I decided to change it because I didn’t anticipate it when writing
the test.

Technically `ErrorOr<T>` can be used to pass any message alongside `T`,
but practically, it is reasonable to assume that the error code is
`ErrorCodes::SUCCESS` when `isError` is false. Therefore, this feature
should be really only used in the weirdest edge cases - if at all.
Even then, it is most likely still preferable to flag it as an error and
just hand the resulting `T` back using the long constructor
`ErrorOr<T>(bool, uint8_t, T)`.

BodgeMaster 7a2c1d7d57 scripts/test: Clean old unit tests before building new ones to avoid confusion
if a unit test fails to build and old unit tests remain in place, this can
lead to confusion when the old test is run anyway.

"Why are some test cases missing?"
"Huh, it failed to build but passed?"

BodgeMaster f5d85da98c lib/nbt: Move the functions for getting tag sizes into the helper namespace, give up on handling lists the same as all other tags
I tried dealing with lists in the same way as with other more basic tags
but came to the conclusion that this is most likely not feasible in the same
way that it is not feasible for compounds. It would require a mini-parser
that can deal with all sorts of tags (including nested lists and compounds).

Instead, an approach more similar to the recursion for compound tags will
be used (using its own function to deal with the missing tag headers ofc).
