[PATCH] tools: add tags and cscope index file generation support

[PATCH] tools: add tags and cscope index file generation support

[Jerin Jacob]

This script generates cscope, gtags, and tags
index files based on EAL environment.
(architecture and OS(linux/bsd))

Selection of the architecture and OS environment
is based on dpdk configuration target(T=)

example usage:
make tags T=x86_64-native-linuxapp-gcc
make cscope T=x86_64-native-linuxapp-gcc
make gtags T=x86_64-native-linuxapp-gcc

I would prefer fallback to RTE_TARGET parsing, or processing all files (
cscope -Rqn ), instead of exiting here, but that is your call.


Also "tags.sh" needs to be moved into "devtools" after latest updates.

I would prefer avoid any fallback(sometimes RTE_TARGET can be "build" also) and
print the usage and exit error if the requirements are not meet.

Sure. I will send v2 to address this.

Very handy. +1.

Could you also add an etags target, for Emacs. Either separately like the 
gtags target or just add it to the tags target:
 
    doetags()
    {
        all_sources | xargs etags -a
    }
    
    # or:

    doctags()
    {
        all_sources | xargs ctags -a
        all_sources | xargs etags -a
    }

It create a TAGS file which should be added to the gitignore rules.

Thanks,

John

What is the purpose of selecting a configuration?
Is it to go quicker in the implementation you are interested in?
In that case, I think we need a catch-all option, because I like
being prompted by vim that several implementations exist and I can
choose one of them.

I think build-tags.sh would be a better name.

On the implementation, I have few comments:
	- is there a way to re-use the skip list when including the related files?
	- you can remove tile from this patch
And for the details:
	- why a bash shebang where /bin/sh would be wider?
	- verbose option should be -v (with getopts)
	- please use $() instead of backquotes
	- please avoid one-line functions used only once like doctags

I can help you with this script if needed.

Yes. That is the hard part to do.

OK. Then we can make T= as optional and if T= is not specified then script can
take all the source files. Thoughts?

I have no time this week.
But do not hesitate to ping me when doing the v2 if you feel I can help.

[PATCH v3] devtools: add tags and cscope index file generation support

[Jerin Jacob]

This script generates cscope, gtags, and tags index files based on
EAL environment(architecture and OS(linux/bsd)).

If EAL environment(config) is not specified, the script generates tag
files based on available source code.

Usage: build-tags.sh [-h] [-v] tags|cscope|gtags|etags [config]

example usage:
./devtools/build-tags.sh cscope
./devtools/build-tags.sh tags x86_64-native-linuxapp-gcc
./devtools/build-tags.sh gtags arm64-armv8a-linuxapp-gcc

v3:
- Added etags target for Emacs(John)
- EAL environment(config) is optional now(Thomas)
- Changed bash shebang to /bin/sh (Thomas)
- getopts based -v and -h option (Thomas)
- used $() instead of backquotes (Thomas)
- Removed "make" based frontend to the script to make it inline with
other devtools scripts in DPDK (Jerin)

v2:
- Moved tag.sh to devtools from scripts
- Rebased to master

This is great, Jerin, thank you!

IMO it would be even better to have this as one of the targets in the master makefile rather than a standalone script, what do you think?

I had it in v2 and then I removed it.
If there are no objection, I will add these targets in Makefile in next
revision.

Example usage:
make tags T=x86_64-native-linuxapp-gcc
make tags

[PATCH v5] devtools: add tags and cscope index file generation support

[Jerin Jacob]

This script generates cscope, gtags, and tags index files based on
EAL environment(architecture and OS(linux/bsd)).

Selection of the architecture and OS environment is based on dpdk
configuration target(T=).If EAL environment(T=) is not specified,
the script generates tag files based on available source code.

Usage: make tags|cscope|gtags|etags [T=config]

example usage:
make cscope
make tags T=x86_64-native-linuxapp-gcc
make gtags T=arm64-armv8a-linuxapp-gcc

v5:
- Added cscope,tags,gtags,etags makefile targets (Cristian)

v4:
- Accommodate the latest "test" directory rework change in master

v3:
- Added etags target for Emacs(John)
- EAL environment(config) is optional now(Thomas)
- Changed bash shebang to /bin/sh (Thomas)
- getopts based -v and -h option (Thomas)
- used $() instead of backquotes (Thomas)
- Removed "make" based frontend to the script to make it inline with
other devtools scripts in DPDK (Jerin)

v2:
- Moved tag.sh to devtools from scripts
- Rebased to master

Re: [PATCH v5] devtools: add tags and cscope index file generation support

[Thomas Monjalon]

Hi,
I have some comments about behaviour, naming and coding style.

22/03/2017 09:30, Jerin Jacob:

> +linuxapp=false
> +bsdapp=false

linuxapp/bsdapp could be renamed to simpler linux/bsd.

> +x86_64=false
> +arm=false

Why not arm32 for consistency?

> +arm64=false
> +ia_32=false

ia_32 should be x86_32

> +ppc_64=false

[...]
> +	make showconfigs | sed 's,^,\t,'

This is assuming the working dir is the dpdk root.
It is assumed elsewhere in the script.
I suggest adding "cd $(dirname $0)/.." at the beginning of the script.

Same comment about arm32 consistency.

... and here x86/x86_32 instead of ia/i686

RTE_TARGET is used to define the build directory.
It will not be defined in this script and it does not really
make sense to enforce it.
I suggest to remove rte_config.h from this script.
Other argument: you can have several build directories
with different configs.

[...]
> +check_valid_config()

It is not a config but a target.
Yes the target is checked against existing config template names.

This "do" keyword could be on the previous line, like you did for if...then.

Better to use an "if" block here.

[...]

More compact grep:
	if echo $2 | grep -q "linuxapp-" ; then

[...]

> +	arm=true

You could define them as true by default.
So the above grep would become:
	echo $2 | grep -q "linuxapp-" || linux=false

[...]

I am a bit surprised by these constructs.
When using sh -e, we should not have a false statement.
I think it should be:
	if $linuxapp ; then linuxapp_sources ; fi

Please use an "if" block here.

No need of ifdef.

Thanks Jerin

[PATCH v6] devtools: add tags and cscope index file generation support

[Jerin Jacob]

This script generates cscope, gtags, and tags index files based on
EAL environment(architecture and OS(linux/bsd)).

Selection of the architecture and OS environment is based on dpdk
configuration target(T=).If EAL environment(T=) is not specified,
the script generates tag files based on available source code.

Usage: make tags|cscope|gtags|etags [T=config]

example usage:
make cscope
make tags T=x86_64-native-linuxapp-gcc
make gtags T=arm64-armv8a-linuxapp-gcc

- Accommodate the latest "test" directory rework change in master

v3:
- Added etags target for Emacs(John)
- EAL environment(config) is optional now(Thomas)
- Changed bash shebang to /bin/sh (Thomas)
- getopts based -v and -h option (Thomas)
- used $() instead of backquotes (Thomas)
- Removed "make" based frontend to the script to make it inline with
other devtools scripts in DPDK (Jerin)

- Moved tag.sh to devtools from scripts
- Rebased to master
