When a link order is unresolvable, decomp-toolkit
now prints out all of the TUs in a cycle, easing
debugging.
Example:
```
Cyclic dependency encountered while resolving link order: Dolphin/os/__start.c -> Dolphin/os/__ppc_eabi_init.cpp -> Dolphin/pad/PadClamp.c -> Dolphin/pad/pad.c
```
Thanks @simonlindholm for the toposort impl.
Extract configuration is now emitted in the output config, so
tooling can load and perform their own tasks on extracted assets
without having to parse YAML.
`header_type`:
- `symbol` (default): Emit a full symbol declaration.
- `raw`: Emit raw array data (for wrapping in your own declaration)
- `none`: Don't emit a header at all. (For custom processing)
`custom_type`/`custom_data`: Passed through to the output config
as-is for custom tasks.
This allows handling path conversions in a more structured way,
as well as avoiding needless UTF-8 checks. All argument inputs
use `Utf8NativePathBuf`, while all config entries use
`Utf8UnixPathBuf`, ensuring that we deserialize/serialize using
forward slashes. We can omit `.display()` and lossy UTF-8
conversions since all paths are known valid UTF-8.
`vfs ls`: Now displays size, detected file format, and decompressed
size (if applicable). `-r`/`--recursive` lists files recursively.
`-s`/`--short` prints only filenames.
`vfs cp`: Copies files recursively when the source is a directory.
`--no-decompress` disables automatic decompression for Yay0/Yaz0.
`-q` disables printing copied files.
`rarc` and `u8` commands are now thin wrappers over `vfs ls` and
`vfs cp`. For example, `rarc list file.arc` is now equivalent to
`vfs ls file.arc:`. `rarc extract file.arc -o out` is equivalent
to `vfs cp file.arc: out`.
Revamps support for container paths and centralizes logic into a VFS (virtual file system) module.
The new VFS architecture supports disc images and any layer of nesting.
For example, the following command works:
`dtk dol info 'Interactive Multi-Game Demo Disc - July 2002 (USA).rvz:files/zz_StarFox051702_e3.tgc:files/default.dol'`
This opens a TGC file inside an RVZ disc image, then reads `default.dol` in the FST.
Another example:
`dtk rel info 'Legend of Zelda, The - The Wind Waker (USA).rvz:files/RELS.arc:mmem/f_pc_profile_lst.rel'`
This opens a RARC archive inside an RVZ disc image, loads the Yaz0-compressed REL and
decompresses it on the fly.
This all operates in memory with minimal overhead, with no need to extract temporary files.
Supported container formats:
- Disc images (ISO/GCM, WIA/RVZ, WBFS, CISO, NFS, GCZ, TGC)
- RARC/SZS and U8 (.arc)
Supported compression formats:
- Yaz0 (SZS)
- Yay0 (SZP)
- NLZSS (.lz)
Additionally, projects can utilize a new configuration key `object_base`:
```
object: orig/GZLE01/sys/main.dol
modules:
- object: orig/GZLE01/files/RELS.arc:rels/mmem/f_pc_profile_lst.rel
```
becomes
```
object_base: orig/GZLE01
object: sys/main.dol
modules:
- object: files/RELS.arc:mmem/f_pc_profile_lst.rel
```
When loading the objects, decomp-toolkit will automatically check the `object_base`
directory for any disc images. (They can be named anything, but must be in the folder
root) If one is found, all objects will be fetched from the disc image itself, rather
than having to extract the files manually.
While still a work in progress, two new `vfs` commands were added: `vfs ls` and `vfs cp`.
These commands are very barebones currently, but allow listing directory contents and
extracting files from decomp-toolkit's vfs representation:
```
❯ dtk vfs ls disc.rvz:
files
sys
❯ dtk vfs ls disc.rvz:sys
boot.bin
bi2.bin
apploader.bin
fst.bin
main.dol
❯ dtk vfs cp disc.rvz:sys/main.dol .
```
Example in splits.txt:
```
file1.cpp: order:0
...
file2.cpp: order:1
...
file3.cpp: order:2
...
```
This ensures that file2.cpp is always
anchored in between 1 and 3 when resolving
the final link order.
- With a map, attempts to detect and handle common BSS automatically
- With a map, attempts to detect and correct inflated common BSS bug (< GC 2.7 linker)
- Support for "stripped" symbols, sometimes required to match inflated common BSS sizes
- Warns on duplicated TUs in a map (other than common BSS)
- Automatically adds `comment:0` to `.s` TUs from a map (avoids linker crash)
Adds an "extract" list to project configuration:
```
extract:
- symbol: SomeData
binary: Lib/SomeData.bin
header: Lib/SomeData.inc
```
This example extracts the data of symbol
`SomeData` to `out_dir/bin/Lib/SomeData.bin`,
and a C array representation to
`out_dir/include/Lib/SomeData.inc`.
