Uses getops to pars command line. Supports -s silence all output -g provide a PASS fail message
@liuguo09 please take a look. |
I have already review this in its previous incarnation. So I give my approval nw. I don't know if we can approvals from the other people on the list. |
The use of '-m 99' in the testing is a little odd. I usuaully use -m 86. This probably raises some tool use questions. The coding standard says: Line Width. Text should not extend past column 78 in the typical C source or header file. Sometimes the nature of the content of a file may require that the lines exceed this limit. This often occurs in header files with naturally long definitions. If the line width must extend 78 lines, then some wider line width may be used in the file provided that it is used consistently. This should match the width of the block comments: Block Comments. Each grouping in the file is separated with a block comment. The block comment consists of:
So picking any fixed value will cause long lines to be missed OR many invalid "long line" error reports. Ideally, we should parse the file first, look at the block comments, make sure that they are the same width, and set the maximum line width automatically. |
@patacongo - would you please build and run this under windows. |
Just noticed... tools/README.txt also needs to be updated. I think just the old Usage comments need to be replaced with the new Usage comments. |
@patacongo - Thank you for noticing. It is added. |
It is not clear the the disinction between warning, error, and fatal makes any sense for coding standby. isn't is a boolean; The code complies to the standard or it does not. One non-compliance is no better or worse than another. |

First let me say I am Pro NuttX coding style. On Slack, I had stated something to the effect of: ...how incredibly readable code is that conforms to the NuttX coding style and to preserve your legacy, this must be part of the inviolables... I said it better there.
Good questions! Here is the short answer to your questions are: it is fence:
For the moment See
For a complete understanding.
[DISCUSSION]
Agreed - a CS should be more digital than analog. But unfortunately the is not the current reality of the NuttX coding style or the current tools. The above comment about If we want to grow the Apache NuttX project we need tooling and a CI that works for us not against us. (When we get to that juncture, I will post something about the poison of a bad CI implementations ) Suffice it to say: having a bad experience on any front, is death to a projects adoption! Since we want pre-comment hooks and CI to check conformity to NuttX coding style. We have several issues to overcome. A proficient NuttX coding style tool would check for conformance, suggest fixes and optionally apply them. We do not have a proficient NuttX coding style tool or set of tools yet. Many of us have had our countless hours of work destroyed by the indent.sh. Remember to NEVER NEVER run indent.sh on a formatted file**Once you've been burned you will learn to commit often and Historical (see groups and lists) there are a lot posts like this:
If we want to grow the project. This can not continue to be the way we expect "embedded talent" to spend their time. It does not scale: ambiguity and non-deterministic processes wastes a great deal resources, time and effort and will result in many drive-by-pr's or forks. The sensible conclusion is to remove the human from the loop and automate it with proper tools. This change is the first step away from this quality of tooling. We have a long way to go. It is my hope that this reporting change in this PR will give us more time to work on proper tooling, I do feel strongly about it's ultimate integration: The API should be a simple invocation with NO ROOM for analog setting or not checking what has been changed! This got batted down previously:
but for all the right reasons Having a bad first experience is death to a projects adoption. REMEMBER: The N00B can use the make command and the PRO can use the script - we are not forcing our 'will' on anyone we are enabling the community to grow and succeed. There is a great line in Patch Adams @0:398 ish |
This one is a little misleading:
There is a "switch" (a boolean) that changes the behavior when the tool reaches the code in the file. It detects this point whn the Private or Public Functions block comment is encountered. It is misleading on C files that contain only global data definitions. For thoses files, there will naturally be no such block comments and and perfectly fine code would generate this fatal error. |
@xiaoxiang781216 I have two functional improvements that I want to make to nxstyle.c, but I will wait for Xiao Xiang to dispose of this PR before I do those. |
@patacongo. I'm glad you have some improvements.
Your options are to:
1 wait
OR
2 do a PR against this Branch in this repo
OR
3 I give you write access to this repo and you can pull this branch and add
your commits on it.
