21 Introduction ~
|
|
|
22 This filetype plugin provides extensive support for editing METAFONT and
|
|
|
23 MetaPost documents, including syntax coloring, indentation, and completion.
|
|
|
24
|
|
|
25 Defining indentation rules for METAFONT and MetaPost code is tricky and
|
|
|
26 somewhat subjective, because the syntax is quite liberal. The plugin uses some
|
|
|
27 heuristics that work well most of the time, but in particular cases you may
|
|
|
28 want to to override the automatic rules, so that the manually defined
|
|
|
29 indentation is preserved by commands like `gg=G`.
|
|
|
30
|
|
|
31 This can be achieved by appending `%>`, `%<`, `%=` or `%!` to a line to
|
|
|
32 explicitly control the indentation of the next line. The `<` and `>` symbols
|
|
|
33 may be repeated many times: for instance, `%>>` will cause the next line to be
|
|
|
34 indented twice. Of course, `%<` means that the next line should be
|
|
|
35 de-indented; `%=` sets the indentation of the next line to be equal to the
|
|
|
36 indentation of the current line; and `%!` means that the indentation of the
|
|
|
37 next line should not change from whatever it has been manually set.
|
|
|
38
|
|
|
39 For example, this is the default indentation of a simple macro:
|
|
|
40 >
|
|
|
41 def foo =
|
|
|
42 makepen(
|
|
|
43 subpath(T-n,t) of r
|
|
|
44 shifted .5down
|
|
|
45 --subpath(t,T) of r shifted .5up -- cycle
|
|
|
46 )
|
|
|
47 withcolor black
|
|
|
48 enddef
|
|
|
49 <
|
|
|
50 By adding the special comments, the indentation can be adjusted arbitrarily:
|
|
|
51 >
|
|
|
52 def foo =
|
|
|
53 makepen(
|
|
|
54 subpath(T-n,t) of r %>
|
|
|
55 shifted .5down %>
|
|
|
56 --subpath(t,T) of r shifted .5up -- cycle %<<<
|
|
|
57 )
|
|
|
58 withcolor black
|
|
|
59 enddef

62 Commands ~
|
|
|
63 *:FixBeginfigs*
|
|
|
64 Renumber beginfig() blocks in the current buffer so that the n-th figure has
|
|
|
65 number n. MetaPost only.

69 Settings ~
|
|
|
70 *'g:mf_other_macros'*
|
|
|
71 Highlight some other basic macro names, e.g., from cmbase, logo, etc. This is
|
|
|
72 set to 1 by default in METAFONT buffers, and it is set to 0 by default in
|
|
|
73 MetaPost buffers.
|
|
|
74
|
|
|
75 *'g:mf_plain_macros'*
|
|
|
76 Highlight keywords defined by plain.mf. This is set to 1 by default in
|
|
|
77 METAFONT buffers, and it is set to 0 by default in MetaPost buffers.
|
|
|
78
|
|
|
79 *'g:mf_plain_modes'*

81 METAFONT buffers, and it is set to 0 by default in MetaPost buffers.
|
|
|
82
|
|
|
83 *'g:mp_close_tag'*
|

|
|
|
85 define:
|
|
|
86 >
|
|
|
87 g:mp_end_tag = ['\<endfoo\>']
|
|
|
88 <
|
|
|
89 any line starting with `endfoo` will be de-indented compared to its previous
|
|
|
90 line.
|
|
|
91 >
|
|
|
92 g:mp_close_tag = []
|
|
|
93 <
|
|
|
94 *'b:mp_metafun'*
|
|
|
95 *'g:mp_metafun'*
|
|
|
96 If set to 1, highlight ConTeXt's MetaFun keywords. MetaPost only.
|
|
|
97 >
|
|
|
98 g:mp_metafun = 0
|
|
|
99 <
|
|
|
100 *'g:mp_mfplain_macros'*
|
|
|
101 Highlight keywords defined by mfplain.mp. MetaPost only.

|
|
|
104 <
|
|
|
105 *'g:mp_open_tag'*
|
|
|
106 Define additional keywords that start indented blocks. For instance, if you
|
|
|
107 define:
|
|
|
108 >
|
|
|
109 g:mp_open_tag = ['\<beginfoo\>']
|
|
|
110 <
|
|
|
111 the line following `beginfoo` will be indented.
|
|
|
112 >
|
|
|
113 g:mp_open_tag = []
|
|
|
114 <
|
|
|
115 *'g:mp_other_macros'*
|
|
|
116 Highlight keywords defined by all base macro packages (boxes, rboxes, format,
|
|
|
117 graph, marith, sarith, string, TEX). This option affects only MetaPost
|
|
|
118 buffers.

|
|
|
