15 # --git generate git commit indications, as shown below
16 # (this is the default if no strings are requested with -t)
19 # generate git commit indication based on commit object only
20 # (ie avoid counting commits)
22 # -i do not generate `+' if git-untracked files are present
25 # generate a form FORM containing TEXT
26 # TEXT can contain newlines (final newline usually undesirable)
27 # if FORM not specified, generates Arg0 Arg1 Arg2 in sequence
28 # character set is SPC 0-9 a-f + * (`*' glyph is `=/=').
30 # We generate a physical indication of which commit was used.
32 # We provide for scaling factors with dynamic variables:
33 # $Commitid_pixelsz if not set, we use 0.8 } multiplied
34 # $Commitid_scale if not set, we use 1.0 } together
35 # $Commitid_depth if not set, we use xy pixel size from above / 2
36 # $Commitid_depth_scale if not set, we use 1.0 (multiplies depth above)
38 # For each form we have
40 # module Commitid_Form_2D() { ... }
41 # module Commitid_Form() { ... }
42 # function Commitid_Form_sz() => [ x, y ]
44 # These have their origin in the bottom left corner. The 3D model
45 # is a positive, has its origin halfway through, and is twice the
46 # depth in height, so it can be added or subtracted.
50 # function Commitid_pixelsz() // $Commitid_pixelsz * $Commitid_scale
51 # function Commitid_depth() // see above
53 # We can generate these forms:
63 # git rev-list --first-parent --count HEAD
64 # typically 3-4 characters but we allow for up to 6
65 # padded with zeroes; if too long we reduce mod 10^n
68 # If tree is dirty, + or * is suffixed, reducing number of
75 # same but split into two lines eg
83 # git-rev-parse HEAD (prefix of requested length)
86 # If tree is dirty, + or * is suffixed to commitid,
87 # reducing number of hex digits by 1.
97 # git-rev-list --first-parent --count HEAD
102 # If tree is dirty, + or * is suffixed to count (but not to
103 # commitid) reducing number of digits by 1.
