A column option string consists of many token separated by either
a space or a comma. A token belongs to one of three groups:
- enabling: always, never and auto
- layout mode: currently plain (which does not layout at all)
- other future tuning flags
git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.

+=============
+
+NAME
+----
+git-column - Display data in columns
+
+SYNOPSIS
+--------
+[verse]
+'git column' [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
+ [--indent=<string>] [--nl=<string>] [--pading=<n>]
+
+DESCRIPTION
+-----------
+This command formats its input into multiple columns.
+
+OPTIONS
+-------
+--command=<name>::
+ Look up layout mode using configuration variable column.<name> and
+ column.ui.
+
+--mode=<mode>::
+ Specify layout mode. See configuration variable column.ui for option
+ syntax.
+
+--raw-mode=<n>::
+ Same as --mode but take mode encoded as a number. This is mainly used
+ by other commands that have already parsed layout mode.
+
+--width=<width>::
+ Specify the terminal width. By default 'git column' will detect the
+ terminal width, or fall back to 80 if it is unable to do so.
+
+--indent=<string>::
+ String to be printed at the beginning of each line.
+
+--nl=<N>::
+ String to be printed at the end of each line,
+ including newline character.
+
+--padding=<N>::
+ The number of spaces between columns. One space by default.

I do not think there is anything that reads column.ui from a configuration
file (or "git -c column.ui") in this step, but later patches seem to use
it from their configuration callback (e.g. git_branch_config()) and at
that point you will segfault because you ignore the case where value is
NULL.

This whole thing looks overly wasteful. How about doing it this way?
const char *it = skip_prefix(var, "column.");
if (!it)
return 0;
if (!strcmp(it, "ui"))
parse "ui";
else if (!strcmp(it, command))
parse "command";
and make the third parameter to column_config() be without the constant
prefix "column."?

A column option string consists of many token separated by either
a space or a comma. A token belongs to one of three groups:
- enabling: always, never and auto
- layout mode: currently plain (which does not layout at all)
- other future tuning flags
git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.

Nice, and thanks I didn't know about skip_prefix. How about this?

+NAME
+----
+git-column - Display data in columns
+
+SYNOPSIS
+--------
+[verse]
+'git column' [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
+ [--indent=<string>] [--nl=<string>] [--pading=<n>]
+
+DESCRIPTION
+-----------
+This command formats its input into multiple columns.
+
+OPTIONS
+-------
+--command=<name>::
+ Look up layout mode using configuration variable column.<name> and
+ column.ui.
+
+--mode=<mode>::
+ Specify layout mode. See configuration variable column.ui for option
+ syntax.
+
+--raw-mode=<n>::
+ Same as --mode but take mode encoded as a number. This is mainly used
+ by other commands that have already parsed layout mode.
+
+--width=<width>::
+ Specify the terminal width. By default 'git column' will detect the
+ terminal width, or fall back to 80 if it is unable to do so.
+
+--indent=<string>::
+ String to be printed at the beginning of each line.
+
+--nl=<N>::
+ String to be printed at the end of each line,
+ including newline character.
+
+--padding=<N>::
+ The number of spaces between columns. One space by default.

If column.* can never be a boolean, this code shouldn't silently ignore
[column]
ui
but explicitly error out. See git_config_string() for an example if you
want to go this route.
On the other hand, it might make sense to equate a "true" with "a sane
default" (i.e. the user declares that s/he trusts whatever default the Git
implementation deems sane), in which case
if (!value)
value = "auto,whatever,column,default,mode";
if (parse_config(colopts, value))
return error("invalid column.%s mode...", ...);
might be a better way to go. If you take this route, a single-token
column.* becomes a variable that takes boolean and more, so the existing
`never` has to gain `no`, `false`, etc. as synonyms, and `true`, `1`,
etc. needs to be interpreted the same as `auto` for consistency.

A column option string consists of many token separated by either
a space or a comma. A token belongs to one of three groups:
- enabling: always, never and auto
- layout mode: currently plain (which does not layout at all)
- other future tuning flags
git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.

Thanks. I'll go with the simple way: error out.

Am I looking at the correct version? Somehow I thought you eliminated
this confusingly named macro in the previous round. Two steps forward,
one step backward???

A column option string consists of many token separated by either
a space or a comma. A token belongs to one of three groups:
- enabling: always, never and auto
- layout mode: currently plain (which does not layout at all)
- other future tuning flags
git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.

Aah.. the beautiful result of having the same series (but probably
different versions) across several machines.. This version should be
the right one with fixes.

+NAME
+----
+git-column - Display data in columns
+
+SYNOPSIS
+--------
+[verse]
+'git column' [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
+ [--indent=<string>] [--nl=<string>] [--pading=<n>]
+
+DESCRIPTION
+-----------
+This command formats its input into multiple columns.
+
+OPTIONS
+-------
+--command=<name>::
+ Look up layout mode using configuration variable column.<name> and
+ column.ui.
+
+--mode=<mode>::
+ Specify layout mode. See configuration variable column.ui for option
+ syntax.
+
+--raw-mode=<n>::
+ Same as --mode but take mode encoded as a number. This is mainly used
+ by other commands that have already parsed layout mode.
+
+--width=<width>::
+ Specify the terminal width. By default 'git column' will detect the
+ terminal width, or fall back to 80 if it is unable to do so.
+
+--indent=<string>::
+ String to be printed at the beginning of each line.
+
+--nl=<N>::
+ String to be printed at the end of each line,
+ including newline character.
+
+--padding=<N>::
+ The number of spaces between columns. One space by default.

Yeah, this looks more like it.

git-column can be used as a pager for other git commands, something
like this:
GIT_PAGER="git -p column --mode='dense color'" git -p branch
The problem with this is that "git -p column" also has $GIT_PAGER set so
the pager runs itself again as another pager. The end result is an
infinite loop of forking. Other git commands have the same problem if
being abused this way.
Check if $GIT_PAGER is already set and stop launching another pager.

COL_COLUMN and COL_ROW fill column by column (or row by row
respectively), given the terminal width and how many space between
columns. All cells have equal width.
Strings are supposed to be in UTF-8. Valid ANSI escape strings are OK.

Normally all cells (and in turn columns) share the same width. This
layout mode can waste space because one long item can stretch our all
columns.
With COL_DENSE enabled, column width is calculated indepdendently. All
columns are shrunk to minimum, then it attempts to push cells of the
last row over to the next column with hope that everything still fits
even there's one row less. The process is repeated until the new layout
cannot fit in given width any more, or there's only one row left
(perfect!).
Apparently, this mode consumes more cpu than the old one, but it makes
better use of terminal space. For layouting one or two screens, cpu
usage should not be detectable.
This patch introduces option handling code besides layout modes and
enable/disable to expose this feature as "dense". The feature can be
turned off by specifying "nodense".
