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

Denton Liu [off-list ref] writes:

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.

Looking good.

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.
