# generate a form FORM containing TEXT
# TEXT can contain newlines (final newline usually undesirable)
# if FORM not specified, generates Arg0 Arg1 Arg2 in sequence
-# character set is SPC 0-9 a-f + * (`*' glyph is `=/=').
+# character set is SPC 0-9 a-f + *
#
# We generate a physical indication of which commit was used.
#
# $Commitid_scale if not set, we use 1.0 } together
# $Commitid_depth if not set, we use xy pixel size from above / 2
# $Commitid_depth_scale if not set, we use 1.0 (multiplies depth above)
+# $Commitid_max_best_scale if not set, we use 2.0 (max mult of xy in Best)
#
# For each form we have
#
#
# We can generate these forms:
#
-# Small3:
-# Small4:
-# Small5:
-# Small6:
-# Small7:
-# Small8:
+# In each case:
+# if tree is dirty, * is suffixed or prefixed to count or commitid
+# if tree has untracked files, + is added
+# (where it is added depends on the Form; in any case it does not
+# change the size, but steals space from digits)
+#
+# Small2 Small3 ... Small10:
# git rev-list --first-parent --count HEAD
# typically 3-4 characters but we allow for up to 6
# padded with zeroes; if too long we reduce mod 10^n
-# eg
-# Small4 1070
-# If tree is dirty, + or * is suffixed, reducing number of
-# digits by 1.
+# eg if the count is 123456
+# Small5 3456*
+# Small8 _*123456 (where _ are spaces)
+# the git objectid is included if it will fit
+# unambiguously and usefully eg
+# Small9 ab*123456
#
-# Small4Q:
-# Small6Q:
-# Small9Q:
-# same but in two lines eg
-# Small4Q 10
-# 70
+# Small2S Small4S ... Small10S:
+# Small3T Small9T:
+# same but split into two lines (S) or three lines (T) eg
+# Small4S 45 Small6T _3
+# 6* 45
+# 6*
#
-# Git4 Git4Q
-# Git6 Git6Q
-# Git8 Git8Q
+# Git2 Git3 ... Git10:
+# Git4S Git6S ... Git10S:
+# Git6T Git9T:
# git-rev-parse HEAD (prefix of requested length)
-# eg
-# Git6 82f2a2
-# If tree is dirty, + or * is suffixed to commitid,
-# reducing number of hex digits by 1.
-
-# Full3
-# Full4
-# Full5
-# Full6
-# Full7
-# Full8
-# Full9
-# Full10
+# eg if the commitid is abcdef0123...
+# Git5 abcd*
+
+# Full4 Full6 ... Full20:
# git-rev-list --first-parent --count HEAD
# git-rev-parse HEAD
+# (all on two lines)
# eg
-# Full6 1070
-# 82f2a2
-# If tree is dirty, + or * is suffixed to count (but not to
-# commitid) reducing number of digits by 1.
+# Full6 abcdef Full8 abcdef01
+# 23456* _123456*
+#
+# Full6T Full9T ... Full30T
+# as Full but commit is split over two lines
