4 Fbpad is a small Linux framebuffer virtual terminal. It manages many
5 terminals through single-letter tags; each tag can hold two terminals.
6 The following table indicates fbpad's key-bindings (m-k means pressing
7 k, while holding the alt key).
9 ============== =======================================
11 ============== =======================================
12 m-c execute a shell (SHELL)
13 m-m execute mail program (MAIL)
14 m-e execute editor program (EDITOR)
15 m-x switch to tag 'x' (TAGS)
16 m-j switch to current tag's alternative terminal
19 m-o jump to the previous tag
20 m-tab show the next terminal
21 m-s create a text screenshot (SCRSHOT)
22 m-y redraw the terminal
23 c-m-e reload the fonts and terminal colors (CLRFILE)
24 c-m-l lock the screen; use PASS to unlock
25 c-m-o disable/enable tag switching
29 m-= split tag horizontally/vertically
31 m-; like m-c but with switching signals
32 ============== =======================================
34 To execute only a single program in fbpad, the program and its
35 arguments should be passed as command line arguments of fbpad. Fbpad
36 executes the specified program in a terminal, disables all terminal
37 switching commands, and exits as soon as the program finishes.
39 Programs like fbpdf, fbvnc, and fbff read the FBDEV environment
40 variable, which can specify the framebuffer device and its drawing
41 region, like "/dev/fb0:1438x448+1+451". Fbpad defines this
42 environment variable when executing a program, so that if a tag is
43 split, the program running in its terminal is limited to its
44 corresponding framebuffer region.
49 To configure fbpad, you should edit conf.h. To get fbpad running you
50 need to make sure FR points to a valid fbpad font (for testing you can
51 try http://litcave.rudi.ir/courr.tf) and SHELL to the shell you want
52 fbpad to execute. Once these are set, you should be able to start
53 fbpad without problems.
55 Fbpad fonts can be generated using fbpad_mkfn program
56 (http://litcave.rudi.ir/). The FR, FI, and FB macros specify the path
57 of fbpad fonts for regular, italic, and bold fonts. If FI or FB is
58 NULL, the regular font is used for italic or bold text.
60 Next, you may want to change the list of fbpad tags by changing TAGS.
61 FGCOLOR and BGCOLOR macros specify foreground and background colors,
62 for instance the FGCOLOR of 2 and BGCOLOR of 0 creates green on black
63 terminals. Individual colors can be customized by editing the hex RGB
64 color description of COLOR* macros. Also SCRSHOT macro specifies where
65 fbpad text screenshots, created by "m-s" command, must be saved.
67 If you want to use fbpad's scrsnap feature, you can edit TAGS_SAVED to
68 change the list of saved terminals. Framebuffer memory is saved and
69 reloaded for these tags, which is very convenient when you are using
70 programs that change the framebuffer simultaneously, like fbpdf.
76 Fbpad supports xterm's 256-color extension, but most programs will not
77 use this extension, unless the $TERM terminfo entry declares this
78 feature. For this purpose, fbpad-256 terminfo file can be created to
79 contain (the two-space identation should be ignored):
85 setab=\E[%?%p1%{8}%<%t4%p1%d%e%p1%{16}%<%t10%p1%{8}%-%d%e48;5;%p1%d%;m,
86 setaf=\E[%?%p1%{8}%<%t3%p1%d%e%p1%{16}%<%t9%p1%{8}%-%d%e38;5;%p1%d%;m,
88 Which can be installed with tic command:
92 The following line should be added to shell's startup script:
96 Note that in order to use this feature and italic fonts in Vim, adding
97 fbpad-256 terminfo is not necessary. Including the following lines in
98 the vimrc file should enable them:
