[PATCH 0/3] [RFC] List all guides in git(1)

[PATCH 0/3] [RFC] List all guides in git(1)

[Philippe Blain via GitGitGadget]

This series adds a list of the guides to git(1).

The first commit adds the misssing guides 'gitcredentials' and
'gitremote-helpers' to command-list.txt. The only missing guide after this
change is 'gitweb.conf', but I think this one is obscure anough, and already
linked to in 'gitweb.txt', that it does not matter much.

The second commit drops the usage of 'common' and 'useful' for guides. This
was suggested as one of two ways forward by Duy in [1] but was not commented
on. I'm CC'ing the people that were CC'ed on that message.

The third commit tweaks 'Documentation/cmd-list.perl' so that it also
generates a list of the guides, which gets included in 'git.txt'. I chose to
put this list just after the end of the list of commands.

[PATCH 1/3] command-list.txt: add missing 'gitcredentials' and 'gitremote-helpers'

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

The guides 'gitcredentials' and 'gitremote-helpers' do not currently
appear in command-list.txt.

'gitcredentials' was forgotten back when guides were added to
command-list.txt in 1b81d8cb19 (help: use command-list.txt for the
source of guides, 2018-05-20).

'gitremote-helpers' was moved to section 7 in 439cc74632 (docs: move
gitremote-helpers into section 7, 2019-03-25), but command-list.txt was
not updated at the time.

Add these two guides to the list of guides in 'command-list.txt', so
that they appear in the output of 'git help --guides', and capitalize
the first word of the description of 'gitcredentials', as was done in
1b81d8c (help: use command-list.txt for the source of guides,
2018-05-20) for the other guides.

While at it, add a comment in Documentation/Makefile to remind developers
to update command-list.txt if they add a new guide.

[PATCH 2/3] help: drop usage of 'common' and 'useful' for guides

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

Since 1b81d8cb19 (help: use command-list.txt for the source of guides,
2018-05-20), all man5/man7 guides listed in command-list.txt appear in
the output of 'git help -g'.

However, 'git help -g' still prefixes this list with "The common Git
guides are:", which makes one wonder if there are others!

In the same spirit, the man page for 'git help' describes the '--guides'
option as listing 'useful' guides, which is not false per se but can
also be taken to mean that there are other guides that exist but are not
useful.

Instead of 'common' and 'useful', use 'Git concept guides' in both
places. To keep the code in line with this change, rename
help.c::list_common_guides_help to list_guides_help.

[PATCH 3/3] git.txt: add list of guides

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

Not all guides are mentioned in the 'git(1)' documentation,
which makes the missing ones somewhat hard to find.

Add a list of the guides to git(1).

Tweak `Documentation/cmd-list.perl` so that it also generates
a file `cmds-guide.txt` which gets included in git.txt.

Also, do not hard-code the manual section '1'. Instead, use a regex so
that the manual section is discovered from the first line of each
`git*.txt` file.

This addition was hinted at in 1b81d8cb19 (help: use command-list.txt for
the source of guides, 2018-05-20).

Who cleans this?  Do we need a change to Makefile?

Oups! I checked /.gitignore, but forgot to thoroughly check the Makefile.

Thanks for the suggestion. I tested it and it works correctly. 
I've incorporated it to v2.

[PATCH v2 0/3] List all guides in git(1)

[Philippe Blain via GitGitGadget]

Changes since v1:

 * Incorporated Junio's suggestion to reduce duplication.

v1: This series adds a list of the guides to git(1).

The first commit adds the misssing guides 'gitcredentials' and
'gitremote-helpers' to command-list.txt. The only missing guide after this
change is 'gitweb.conf', but I think this one is obscure anough, and already
linked to in 'gitweb.txt', that it does not matter much.

The second commit drops the usage of 'common' and 'useful' for guides. This
was suggested as one of two ways forward by Duy in [1] but was not commented
on. I'm CC'ing the people that were CC'ed on that message.

The third commit tweaks 'Documentation/cmd-list.perl' so that it also
generates a list of the guides, which gets included in 'git.txt'. I chose to
put this list just after the end of the list of commands.

[PATCH v2 1/3] command-list.txt: add missing 'gitcredentials' and 'gitremote-helpers'

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

The guides 'gitcredentials' and 'gitremote-helpers' do not currently
appear in command-list.txt.

'gitcredentials' was forgotten back when guides were added to
command-list.txt in 1b81d8cb19 (help: use command-list.txt for the
source of guides, 2018-05-20).

'gitremote-helpers' was moved to section 7 in 439cc74632 (docs: move
gitremote-helpers into section 7, 2019-03-25), but command-list.txt was
not updated at the time.

Add these two guides to the list of guides in 'command-list.txt', so
that they appear in the output of 'git help --guides', and capitalize
the first word of the description of 'gitcredentials', as was done in
1b81d8c (help: use command-list.txt for the source of guides,
2018-05-20) for the other guides.

While at it, add a comment in Documentation/Makefile to remind developers
to update command-list.txt if they add a new guide.

[PATCH v2 2/3] help: drop usage of 'common' and 'useful' for guides

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

Since 1b81d8cb19 (help: use command-list.txt for the source of guides,
2018-05-20), all man5/man7 guides listed in command-list.txt appear in
the output of 'git help -g'.

However, 'git help -g' still prefixes this list with "The common Git
guides are:", which makes one wonder if there are others!

In the same spirit, the man page for 'git help' describes the '--guides'
option as listing 'useful' guides, which is not false per se but can
also be taken to mean that there are other guides that exist but are not
useful.

Instead of 'common' and 'useful', use 'Git concept guides' in both
places. To keep the code in line with this change, rename
help.c::list_common_guides_help to list_guides_help.

[PATCH v2 3/3] git.txt: add list of guides

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

Not all man5/man7 guides are mentioned in the 'git(1)' documentation,
which makes the missing ones somewhat hard to find.

Add a list of the guides to git(1) by leveraging the existing
`Documentation/cmd-list.perl` script to generate a file `cmds-guide.txt`
which gets included in git.txt.

Instead of hard-coding the list of command categories in both
`Documentation/Makefile` and `Documentation/cmd-list.perl`, make the
Makefile the authoritative source and tweak `cmd-list.perl` so that it
receives the list of command categories as argument.

Also, do not hard-code the manual section '1'. Instead, use a regex so
that the manual section is discovered from the first line of each
`git*.txt` file.

This addition was hinted at in 1b81d8cb19 (help: use command-list.txt for
the source of guides, 2018-05-20).

I think the "dedup the list of cmds-$category.txt" is logically a
separate step from "we forgot to add guide category so add it", so
either (1) "add guide twice, and then refactor" or (2) "refactor
before adding guide, and then add guide only in one place" would be
more appropriate than (3) "add guide while refactoring".  IMHO, (2)
would make the most sense.

Thanks.

I agree that (2) makes the most sense, I've split it for v3. (Your "SQUASH???" message on pb/guide-docs 
may have mislead me :)

[PATCH v3 0/4] List all guides in git(1)

[Philippe Blain via GitGitGadget]

Changes since v2:

 * Split the third commit following Junio's suggestion

Question for Junio: Since the new commit 3/4 comes entirely from your
suggestion, I've attributed authorship to you, but I've added my own
sign-off because Gitgitgadget requires sign-off on each commit. Please let
me know if I should have proceeded differently.

v2:

 * Incorporated Junio's suggestion to reduce duplication.

v1: This series adds a list of the guides to git(1).

The first commit adds the misssing guides 'gitcredentials' and
'gitremote-helpers' to command-list.txt. The only missing guide after this
change is 'gitweb.conf', but I think this one is obscure anough, and already
linked to in 'gitweb.txt', that it does not matter much.

The second commit drops the usage of 'common' and 'useful' for guides. This
was suggested as one of two ways forward by Duy in [1] but was not commented
on. I'm CC'ing the people that were CC'ed on that message.

The third commit tweaks 'Documentation/cmd-list.perl' so that it also
generates a list of the guides, which gets included in 'git.txt'. I chose to
put this list just after the end of the list of commands.

[PATCH v3 1/4] command-list.txt: add missing 'gitcredentials' and 'gitremote-helpers'

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

The guides 'gitcredentials' and 'gitremote-helpers' do not currently
appear in command-list.txt.

'gitcredentials' was forgotten back when guides were added to
command-list.txt in 1b81d8cb19 (help: use command-list.txt for the
source of guides, 2018-05-20).

'gitremote-helpers' was moved to section 7 in 439cc74632 (docs: move
gitremote-helpers into section 7, 2019-03-25), but command-list.txt was
not updated at the time.

Add these two guides to the list of guides in 'command-list.txt', so
that they appear in the output of 'git help --guides', and capitalize
the first word of the description of 'gitcredentials', as was done in
1b81d8c (help: use command-list.txt for the source of guides,
2018-05-20) for the other guides.

While at it, add a comment in Documentation/Makefile to remind developers
to update command-list.txt if they add a new guide.

[PATCH v3 2/4] help: drop usage of 'common' and 'useful' for guides

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

Since 1b81d8cb19 (help: use command-list.txt for the source of guides,
2018-05-20), all man5/man7 guides listed in command-list.txt appear in
the output of 'git help -g'.

However, 'git help -g' still prefixes this list with "The common Git
guides are:", which makes one wonder if there are others!

In the same spirit, the man page for 'git help' describes the '--guides'
option as listing 'useful' guides, which is not false per se but can
also be taken to mean that there are other guides that exist but are not
useful.

Instead of 'common' and 'useful', use 'Git concept guides' in both
places. To keep the code in line with this change, rename
help.c::list_common_guides_help to list_guides_help.

[PATCH v3 4/4] git.txt: add list of guides

[Philippe Blain via GitGitGadget]

From: Philippe Blain <levraiphilippeblain@gmail.com>

Not all man5/man7 guides are mentioned in the 'git(1)' documentation,
which makes the missing ones somewhat hard to find.

Add a list of the guides to git(1) by leveraging the existing
`Documentation/cmd-list.perl` script to generate a file `cmds-guide.txt`
which gets included in git.txt.

Also, do not hard-code the manual section '1'. Instead, use a regex so
that the manual section is discovered from the first line of each
`git*.txt` file.

This addition was hinted at in 1b81d8cb19 (help: use command-list.txt
for the source of guides, 2018-05-20).
