[PATCH 0/3] docs: misc cleanup

[PATCH 0/3] docs: misc cleanup

[Denton Liu]

Just a couple of documentation fixes that I noticed in passing today.
Nothing too controversial.

This branch is based on 'maint'.

Denton Liu (3):
  i18n.txt: camel case and monospace "i18n.commitEncoding"
  git-cat-file.txt: monospace args and placeholders
  git-cat-file.txt: remove references to "sha1"

[PATCH 1/3] i18n.txt: camel case and monospace "i18n.commitEncoding"

[Denton Liu]

In 95791be750 (doc: camelCase the i18n config variables to improve
readability, 2017-07-17), the other i18n config variables were
camel cased. However, this one instance was missed.

Camel case and monospace "i18n.commitEncoding" so that it matches the
surrounding text.

I find this new terminology confusing and ambiguous. To me, this seems
to be saying that it is a hex representation of the entire object
rather than a hex representation of the hash of the object. Perhaps
say either "hex representation of the hash of the object" or "hex
representation of the object ID"?

Same issue. "hex representation of the delta base object" sounds
misleading. Should probably mention "hash of the" in there somewhere
or something.

While I agree that it is a good idea to move away from an explicit
mention of "40", I do not see why we would want to explain "object
name" not as "object name" but as "object ID".  IOW, s/ID/name/.

Likewise.  Documentation/glossary-content.txt says "object name" is
the canonical term, with "object identifier", "hash" etc. as its

Thanks, but whenever you noticed an issue like "Ah, here we used an
incorrect spelling i18n.commitencoding", please make it a habit to
see if we did exactly the same mistake elsewhere (you have been
working with Git long enough to know how cheap such a check is):

    $ git grep -F -e i18n.commitencoding -- \
         Documentation/ ':!Documentation/RelNotes/'

and you would have found three other instances.

This obviously does not have to be part of this miniseries, but I
wonder if we should have a list of all the configuration variables
in one place that we can use to record the canonical spelling of
these variables.  As

$ git grep -h -E -i \
	-e '^[a-z][-a-z0-9]*\.[a-z][-a-z0-9]*::' \
	-e '^[a-z][-a-z0-9]*\.(\*|<?[a-z][-a-z0-9]*>?)\.(\*|<?[a-z][-a-z0-9]*>?)::' \
	Documentation/config

gives many hits with camelCased names, it might be a good place to
start.

Pretending that the above gives a good "canonical list" (it does not
yet, if you look at the hits), I got curious how far we can go.

Massaging the output from the above into config-variables.lst

$ ... above command ... |
  sed -e 's/::$//' |
  sort -u >config-variables.lst

and then to extract use of these tokens in the main part of the
documentation like this:

$ git grep -h -o -i -F -f config-variables.lst -- \
  Documentation/ ':!Documentation/RelNotes/' |
  sort -u >config-usage.lst

gives us something we can compare with the "canonical" usage list.

$ comm -3 config-usage.lst config-variables.lst

Some of them may be false hits, some may be showing that the copy in
Documentation/config/ are spelled in all lowercase, but the majority
of the hits above seem to be genuine errors similar to what you fixed
in your patch.

Thanks.

Denton's authorship seems to have been lost (no From: header). Was

I didn't even notice.

I actually expect that Denton will produce a more complete series
based on the "comm -3" output, so that this patch itself (or its
authorship) won't matter ;-)

And I also expect that somebody will take the "two greps and comm"
trick I showed and wrap it into some form of doc-lint.  Hint, hint...

Thanks.

[PATCH v3 0/3] doc: spell configuration variable names in camelCase

[Junio C Hamano]

I said in the first review on Denton's patch

    This obviously does not have to be part of this miniseries, but I
    wonder if we should have a list of all the configuration variables
    in one place that we can use to record the canonical spelling of
    these variables.  As

    $ git grep -h -E -i \
	    -e '^[a-z][-a-z0-9]*\.[a-z][-a-z0-9]*::' \
	    -e '^[a-z][-a-z0-9]*\.(\*|<?[a-z][-a-z0-9]*>?)\.(\*|<?[a-z][-a-z0-9]*>?)::' \
	    Documentation/config

    gives many hits with camelCased names, it might be a good place to
    start.

    Pretending that the above gives a good "canonical list" (it does not
    yet, if you look at the hits), I got curious how far we can go.

    Massaging the output from the above into config-variables.lst

    $ ... above command ... |
      sed -e 's/::$//' |
      sort -u >config-variables.lst

    and then to extract use of these tokens in the main part of the
    documentation like this:

    $ git grep -h -o -i -F -f config-variables.lst -- \
      Documentation/ ':!Documentation/RelNotes/' |
      sort -u >config-usage.lst

    gives us something we can compare with the "canonical" usage list.

    $ comm -3 config-usage.lst config-variables.lst
    blame.blankboundary
    core.excludesfile
    core.filemode
    core.gitproxy
    core.ignorestat
    core.logallrefupdates
    core.repositoryformatversion
    core.trustCtime
    http.sslverify
    http.sslversion
    i18n.commitencoding
    push.pushoption
    remote.<name>.partialCloneFilter
    remote.pushdefault
    repack.UseDeltaBaseOffset
    sendemail.aliasesfile
    showbranch.default
    transfer.hiderefs
    uploadArchive.allowUnreachable

    Some of them may be false hits, some may be showing that the copy in
    Documentation/config/ are spelled in all lowercase, but the majority
    of the hits above seem to be genuine errors similar to what you fixed
    in your patch.

    Thanks.

and as I identified a handful of low hanging fruits that way, here
are a few patches on top of his patch that started the whole thing.

I think we should make sure Documentation/config/*.txt 

 - spells all the configuration variables in the way we want to see
   them, and

 - covers all the configuration variables.

before we can proceed with more low hanging fruits with confidence,
as I do think the coverage is very good, but I know it is not 100%,
and the eventual goal should be to make sure we can teach lint-docs
to catch these before the reviewers even see them.

[PATCH v3 1/3] i18n.txt: camel case and monospace "i18n.commitEncoding"

From: Denton Liu <liu.denton@gmail.com>

In 95791be750 (doc: camelCase the i18n config variables to improve
readability, 2017-07-17), the other i18n config variables were
camel cased. However, this one instance was missed.

Camel case and monospace "i18n.commitEncoding" so that it matches the
surrounding text.
