I found a couple of issues when I revisited the argparse_autotest
output, so got this patchset.
Chengwen Feng (4):
argparse: refine error message
argparse: remove dead code
argparse: fix argument flags operate as uint32 type
test/argparse: refine testcases

The judgement "obj->callback == NULL" is dead code which can't be
reached, because verify_arg_saver() already make sure obj->callback
must not be NULL when arg->val_saver is NULL.

The struct rte_argparse_arg's flags was 64bit type, uint64_t should be
used instead of uint32_t where the operation happened.
Also, the flags' bit16 was also unused, so don't test bit16 in testcase
test_argparse_invalid_arg_flags.

Refine testcases, including:
1. add testcase comment.
2. argv[0] should set obj->prog_name.
3. set val_set as NULL in test_argparse_invalid_arg_flags, let it
test to the specified code logic.
4. enable index verification in opt_callback_parse_int_of_no_val.

Something is strange.
An enum in C is represented as an int.
Plus, this enum type is not used anywhere:
lib/argparse/rte_argparse.h:enum rte_argparse_flag {
lib/argparse/rte_argparse.h: /** @see rte_argparse_flag */
I understand the flags are a bitmask.
So please remove this enum and define macros instead.

If flags is a uint64_t, use RTE_BIT64().
I don't know the argparse API, but why do we need this hardcoded (and
hard to understand) ~3 value?
Can it be expressed with the flags defined in the API?

I found a couple of issues when I revisited the argparse_autotest
output, so got this patchset.
Chengwen Feng (5):
argparse: refine error message
argparse: remove dead code
argparse: replace flag enum with marco
argparse: fix argument flags operate as uint32 type
test/argparse: refine testcases
---
v2: address David Marchand's comment:
- replace flag enum with marco.
- replace flag's hardcode with macro in test_argparse.c.

The judgement "obj->callback == NULL" is dead code which can't be
reached, because verify_arg_saver() already make sure obj->callback
must not be NULL when arg->val_saver is NULL.

The struct rte_argparse_arg's flags was 64bit type, uint64_t should be
used instead of uint32_t where the operation happened.
Also, the flags' bit16 was also unused, so don't test bit16 in testcase
test_argparse_invalid_arg_flags.

2024-03-07 13:07 ` [PATCH v2 4/5] argparse: fix argument flags operate as uint32 type Chengwen Feng

From: Chengwen Feng @ 2024-03-07 13:07 UTC (permalink / raw)
To: thomas, dev, david.marchand
Refine testcases, including:
1. add testcase comment.
2. argv[0] should set obj->prog_name.
3. set val_set as NULL in test_argparse_invalid_arg_flags, let it
test to the specified code logic.
4. enable index verification in opt_callback_parse_int_of_no_val.
Fixes: 6c5c6571601c ("argparse: verify argument config")
Fixes: 31ed9f9f43bb ("argparse: parse parameters")

The lowest two bits was a represent whether has value.

Its not part of API, I defined a macro in test_argparse.c to express its meaning in v2.

Done in v2, defined macros in test_argpase.c and express with multi-marco's or value.

it was good to get rid of the enum but will the above macros expand to
signed or unsigned integer given the type of field could we make sure
they expand unsigned?

Afaiu, those should expand to unsigned:
#define RTE_SHIFT_VAL64(val, nr) (UINT64_C(val) << (nr))

I found a couple of issues when I revisited the argparse_autotest
output, so got this patchset.
Chengwen Feng (6):
argparse: refine error message
argparse: remove dead code
argparse: replace flag enum with marco
argparse: fix argument flags operate as uint32 type
test/argparse: refine testcases
argparse: fix doc don't display two hyphens
---
v3:
- address Thomas's comment on 4/6 comit.
- add commit: fix doc don't display two hyphens.
v2: address David Marchand's comment:
- replace flag enum with marco.
- replace flag's hardcode with macro in test_argparse.c.

The judgement "obj->callback == NULL" is dead code which can't be
reached, because verify_arg_saver() already make sure obj->callback
must not be NULL when arg->val_saver is NULL.

The enum rte_argparse_flag's value is u64, but an enum in C is
represented as an int. This commit replace these enum values with
macro.

To: thomas, david.marchand; +Cc: dev
The struct rte_argparse_arg's flags was 64bit type, uint64_t should be
used instead of uint32_t where the operation happened.
Also, the flags' bit16 was also unused, so don't test bit16 in testcase
test_argparse_invalid_arg_flags.
In addition, this commit introduces two bitmask marcros and removes an
internal duplicate macro.
Fixes: 6c5c6571601c ("argparse: verify argument config")
Fixes: 31ed9f9f43bb ("argparse: parse parameters")

Refine testcases, including:
1. add testcase comment.
2. argv[0] should set obj->prog_name.
3. set val_set as NULL in test_argparse_invalid_arg_flags, let it
test to the specified code logic.
4. enable index verification in opt_callback_parse_int_of_no_val.
Fixes: 6c5c6571601c ("argparse: verify argument config")
Fixes: 31ed9f9f43bb ("argparse: parse parameters")

With the line in rst file:
The single mode: "--aaa" or "-a".
corresponding line in html doc:
The single mode: -aaa or -a.
the two hyphens (--aaa) become one (-aaa).
According to [1], this commit uses the backquote (``xxx``) to fix it.
And for consistency, use this format for all arguments.
Fixes: e3e579f5bab5 ("argparse: introduce argparse library")

Don't you want to make it part of the API?
I thought it was what you did in this v3.

I found a couple of issues when I revisited the argparse_autotest
output, so got this patchset.
Chengwen Feng (6):
argparse: refine error message
argparse: remove dead code
argparse: replace flag enum with marco
argparse: fix argument flags operate as uint32 type
test/argparse: refine testcases
argparse: fix doc don't display two hyphens
---
v4: address Thomas's comment on 4/6 commit:
- remove unused macros TEST_ARGPARSE_FLAG_HAS_ARG_BITMASK and
TEST_ARGPARSE_FLAG_VAL_TYPE_BITMASK.
v3:
- address Thomas's comment on 4/6 comit.
- add commit: fix doc don't display two hyphens.
v2: address David Marchand's comment:
- replace flag enum with marco.
- replace flag's hardcode with macro in test_argparse.c.

The judgement "obj->callback == NULL" is dead code which can't be
reached, because verify_arg_saver() already make sure obj->callback
must not be NULL when arg->val_saver is NULL.

The struct rte_argparse_arg's flags was 64bit type, uint64_t should be
used instead of uint32_t where the operation happened.
Also, the flags' bit16 was also unused, so don't test bit16 in testcase
test_argparse_invalid_arg_flags.
In addition, this commit introduces two bitmask marcros and removes an
internal duplicate macro.

Refine testcases, including:
1. add testcase comment.
2. argv[0] should set obj->prog_name.
3. set val_set as NULL in test_argparse_invalid_arg_flags, let it
test to the specified code logic.
4. enable index verification in opt_callback_parse_int_of_no_val.
Fixes: 6c5c6571601c ("argparse: verify argument config")
Fixes: 31ed9f9f43bb ("argparse: parse parameters")

With the line in rst file:
The single mode: "--aaa" or "-a".
corresponding line in html doc:
The single mode: -aaa or -a.
the two hyphens (--aaa) become one (-aaa).
According to [1], this commit uses the backquote (``xxx``) to fix it.
And for consistency, use this format for all arguments.
Fixes: e3e579f5bab5 ("argparse: introduce argparse library")

In v3 I defined two macros: RTE_ARGPARSE_HAS_VAL_BITMASK and RTE_ARGPARSE_VAL_TYPE_BITMASK in API file.
but forgot to remove the above two TEST_ARGPARSE_XXX_BITMASK macros in v3.
I already send v4 to fix it, please review it.

I'd like to get an approval from someone else for the API changes here.
I feel it is better to wait post 24.03.
Anyway it is a fresh experimental API.
