nvme-lint is a tool that uses Camelot-py and Poppler to validate tables in NVMe specification documents.
On Debian these packages are required:
python
pip
poppler-utils
libgl1
Before you can start using nvme-lint you must have pdftohtml in your PATH.
Write the command pdftohtml -v to verify that it is available.
- Install by running:
pip install nvme-lint
To validate a NVMe specification file run the command:
nvme-lint file_name
You can also run the tool directly from the source directory with the command:
python -m nvme_lint
nvme-lint will extract every table from a NVMe specification pdf file, unless a target- or ignore-file is provided. Afterwards, it will proceed to parse and validate the tables.
The flags for nvme-lint are defined below:
usage: nvme-lint [-h] [-l LOG] [-i IGNORE] [-t TARGET] [-y] file
positional arguments:
file
The pdf file containing the tables to validate
options:
-h, --help
show this help message and exit
-l LOG, --log LOG
The logging level. Possible values in order of severity: DEBUG, INFO, WARNING, ERROR, CRITICAL
-i IGNORE, --ignore IGNORE
A .txt file containing figure numbers to ignore, each number should go on a separate line.
This file will be ignored if a target is specified
-t TARGET, --target TARGET
A .txt file containing figure numbers to validate, each number should go on a separate line.
If this file is specified only the figure numbers included will be validated
-y, --yaml
If this flag is set, the content of the tables will be written to 'output.yaml'
NOTE: If you have a file called `output.yaml` in the directory you call `nvme-lint` from, it will be overwritten
During the process nvme-lint checks for the following:
| Issue | Log message |
|---|---|
| Incorrect format for the table captions | Encountered a problem with the caption to Figure (figure number) |
| Incorrect format of footnotes | (value) should be 'NOTES' |
| Columns called 'bit' instead of 'bits' | 'bit' instead of 'bits' |
| Columns called 'byte' instead of 'bytes' | 'byte' instead of 'bytes' |
| Incorrect format for bit- and byte-ranges (n to m instead of m:n) | (bytes / bits) range is of the wrong format: (value) |
| Hexadecimal values in bits- and bytes-columns | (bytes / bits) value is of the wrong type: (value) |
| Incorrect ordering for bits- and bytes-columns | (bytes / bits) are in wrong order |
| Incorrect ordering for bits- and bytes-ranges | (bytes / bits) range is in wrong order: (value) |
| Overlapping bits or bytes | overlap of (bytes / bits) |
| Holes in the bits or bytes | hole in (bytes / bits) |
| Incorrect sum of bits or bytes (not a power of 2) | sum of (bytes / bits) is not a power of 2 |
| Incorrect sum of bits for commands | bits doesn't sum up to (32 / 64) |
The messages from nvme-lint will be outputted to the terminal and the file nvme-lint.log.
