.TH SFED 1 local .SH NAME sfed \- simple font editor .SH SYNOPSIS sfed fontname .SH DESCRIPTION .I Sfed allows the editing of fonts that are in the Berkeley font format. It is useful for creating new fonts, changing glyphs (a .IR glyph , in this context, is the bit pattern of a character in a font), and adjusting the position at which .IR vtroff (1) prints a glyph relative to the glyphs around it in a piece of text. .PP The .I fontname argument is the name of the font that is to be edited. .PP .I Sfed, when invoked, prompts for a glyph. It has several mechanisms by which nonstandard glyphs may be accessed. Entering a number between 0 and 256 will give the glyph at that offset from the beginning of the font (note that this means that the glyphs for the digits 0 through 9 cannot be selected using this method). For other characters, such as the plus sign, preceding the glyph's selection with a tilde (~), will cause .I sfed to edit that glyph. Any glyph from one's terminal keyboard may be selected with the ~ operator. To quit, type control-D. .PP .I sfed works by placing an array of asterisks (*'s) and spaces into a temporary file along with information about the glyph's relative placement. It then invokes .IR vi (1) or the editor specified by the EDITOR environment variable (see .IR environ (5)) on the temporary file and allows one to edit the glyph. When the editing session is terminated, .I sfed rereads the glyph into a buffer within sfed (there is one such buffer for each glyph). It writes these buffers back into the file .I fontname just before it exits. The temporary file is removed. .SH FILES .TP 10 /tmp/fd* temporary file that holds a glyph's pattern. .SH SEE ALSO environ(5), nroff(1), vfont(5), vfontinfo(1), vi(1) .br The Berkeley Font Catalog .br An Introduction to Display Editing With VI .SH DIAGNOSTICS Sfed: bad input: <<CHARACTER>>. Please try again. .br Sfed: offset <<NUMBER>> is out of range. Please try again. .br Complains about not being able to access the temporary or font files.
