Note (1) An ALIAS that begins in column one. This is handled by the lexical analyzer.
Note (2) A BOOLEAN feature that begins after column one but is the first feature on the feature line.
This is handled by the lexical analyzer.
Note (3) A NUMERIC feature that begins after column one but is the first feature on the feature line.
This is handled by the lexical analyzer.
Note (4) A STRING feature that begins after column one but is the first feature on the feature line.
This is handled by the lexical analyzer.
The lexical conventions for terminfo descriptions are as follows:
1. White space consists of the <space> and <tab> characters.
2. An ALIAS may contain any graph characters other than comma (,), slash (/), and bar (|).
(Graph characters are those characters for which isgraph() returns nonzero; see ctype (3C).)
3. A LONGNAME may contain any print characters other than comma (,) and bar (|). (Print
characters are those characters for which isprint() returns nonzero; see ctype (3C).)
4. A BOOLEAN feature may contain any print characters other than comma (,), equals (=), and
pound sign (#).
5. A NUMERIC feature consists of:
a. A name which may contain any print character other than comma (,), equals (=), and
pound sign (#).
b. The pound sign (#) character.
c. A positive integer which conforms to the C language convention for integer constants.
6. A STRING feature consists of:
a. A name which may contain any print character other than comma (,), equals (=), and
pound sign (#).
b. The equals (=) character.
c. A string which may contain any print characters other than comma (,).
7. White space immediately following a comma (,) is ignored.
8. Comments consist of the beginning of a line, optional white space, a required pound sign (#),
and a terminating end of line.
9. A header line must begin in column one.
10. A feature line must not begin in column one.
11. Blank lines are ignored.
