2022-01-28Add custom allocator supportDavid Robillard1-16/+32
2022-01-28Make environments and sinks part of the worldDavid Robillard1-3/+3
Although functions/components that require minimal pre-existing state are nice, these allocate memory and could potentially share resources. So, give them a pointer to a world which can be used to configure such things. In particular, this is working towards supporting custom allocators everywhere.
2022-01-28Fix handling of deferred write errors that happen when closingDavid Robillard1-1/+1
2022-01-28Use more human-readable status codesDavid Robillard1-4/+4
2022-01-28Add "contextual" output optionDavid Robillard1-1/+2
This is mainly for developer or power-user cases, where one wants to look at some data for investigation or debugging. In such cases, it's common for the set of prefixes to be implicitly known (because they are baked in to the application, for example), so printing them just produces a large amount of redundant noise. That said, it can also be useful programmatically, because it allows several snippets to be written independently and ultimately concatenated (with a header to define the prefixes) without redundancy.
2022-01-28Simplify input stream APIDavid Robillard1-13/+21
More or less the same rationale as the previous commit, but for reading. This makes for nice symmetry with writing, at the cost of a slightly more annoying reader interface since the source doesn't know its block size or name.
2022-01-28Simplify output stream APIDavid Robillard1-1/+1
This makes the paging mechanism an internal detail once again. While it's conceptually elegant to simply have a single write interface and have the block dumper just be another implementation of that, unfortunately it is not practical. The inlining of serd_block_dumper_write() is a significant performance boost, because it avoids a non-inlinable function call of overhead per character. Compared to the SerdByteSink approach, this removes the burden and overhead of needing to dynamically allocate the structure itself.
2022-01-28Make tools read stdin by defaultDavid Robillard1-2/+5
2022-01-28Replace serdi with more fine-grained toolsDavid Robillard1-0/+287
Especially with the new functionality, the complexity of the command-line interface alone was really becoming unmanageable. The serdi implementation also had the highest cyclomatic complexity of the entire codebase by a huge margin. So, take a page from the Unix philosophy and split serdi into several more finely-honed tools that can be freely composed. Though there is still unfortunately quite a bit of option overlap between them due to the common details of reading RDF, I think the resulting tools are a lot easier to understand, both from a user and a developer perspective.
