tic - the terminfo entry-description compiler
tic [-1CGILNTVacfgrstx] [-e names] [-o dir] [-R subset] [- v[n]] [-w[n]] file
The command tic translates a terminfo file from source for- mat into compiled format. The compiled format is necessary for use with the library routines in ncurses(3). The results are normally placed in the system terminfo directory /usr/share/terminfo. There are two ways to change this behavior. First, you may override the system default by setting the variable TERMINFO in your shell environment to a valid (existing) directory name. Secondly, if tic cannot get access to /usr/share/terminfo or your TERMINFO directory, it looks for the directory $HOME/.terminfo; if that directory exists, the entry is placed there. Libraries that read terminfo entries are expected to check for a TERMINFO directory first, look at $HOME/.terminfo if TERMINFO is not set, and finally look in /usr/share/terminfo. -1 restricts the output to a single column -a tells tic to retain commented-out capabilities rather than discarding them. Capabilities are commented by prefixing them with a period. This sets the -x option, because it treats the commented-out entries as user- defined names. If the source is termcap, accept the 2- character names required by version 6. Otherwise these are ignored. -C Force source translation to termcap format. Note: this differs from the -C option of infocmp(1) in that it does not merely translate capability names, but also translates terminfo strings to termcap format. Capa- bilities that are not translatable are left in the entry under their terminfo names but commented out with two preceding dots. -c tells tic to only check file for errors, including syn- tax problems and bad use links. If you specify -C (-I) with this option, the code will print warnings about entries which, after use resolution, are more than 1023 MirOS BSD #10-current Printed 4.7.2014 1 tic(1) UNIX Programmer's Manual tic(1) (4096) bytes long. Due to a fixed buffer length in older termcap libraries (and a documented limit in ter- minfo), these entries may cause core dumps. -e names Limit writes and translations to the following comma- separated list of terminals. If any name or alias of a terminal matches one of the names in the list, the entry will be written or translated as normal. Other- wise no output will be generated for it. The option value is interpreted as a file containing the list if it contains a '/'. (Note: depending on how tic was com- piled, this option may require -I or -C.) -f Display complex terminfo strings which contain if/then/else/endif expressions indented for readabil- ity. -G Display constant literals in decimal form rather than their character equivalents. -g Display constant character literals in quoted form rather than their decimal equivalents. -I Force source translation to terminfo format. -L Force source translation to terminfo format using the long C variable names listed in <term.h> -N Disable smart defaults. Normally, when translating from termcap to terminfo, the compiler makes a number of assumptions about the defaults of string capabilities reset1_string, carriage_return, cursor_left, cursor_down, scroll_forward, tab, newline, key_backspace, key_left, and key_down, then attempts to use obsolete termcap capabilities to deduce correct values. It also normally suppresses output of obsolete termcap capabilities such as bs. This option forces a more literal translation that also preserves the obsolete capabilities. -odir Write compiled entries to given directory. Overrides the TERMINFO environment variable. -Rsubset Restrict output to a given subset. This option is for use with archaic versions of terminfo like those on SVr1, Ultrix, or HP/UX that do not support the full set of SVR4/XSI Curses terminfo; and outright broken ports like AIX 3.x that have their own extensions incompati- ble with SVr4/XSI. Available subsets are "SVr1", MirOS BSD #10-current Printed 4.7.2014 2 tic(1) UNIX Programmer's Manual tic(1) "Ultrix", "HP", "BSD" and "AIX"; see terminfo(5) for details. -r Force entry resolution (so there are no remaining tc capabilities) even when doing translation to termcap format. This may be needed if you are preparing a termcap file for a termcap library (such as GNU termcap through version 1.3 or BSD termcap through 4.3BSD) that does not handle multiple tc capabilities per entry. -s Summarize the compile by showing the directory into which entries are written, and the number of entries which are compiled. -T eliminates size-restrictions on the generated text. This is mainly useful for testing and analysis, since the compiled descriptions are limited (e.g., 1023 for termcap, 4096 for terminfo). -t tells tic to discard commented-out capabilities. Nor- mally when translating from terminfo to termcap, untranslatable capabilities are commented-out. -V reports the version of ncurses which was used in this program, and exits. -vn specifies that (verbose) output be written to standard error trace information showing tic's progress. The optional integer n is a number from 1 to 10, inclusive, indicating the desired level of detail of information. If n is omitted, the default level is 1. If n is specified and greater than 1, the level of detail is increased. -wn specifies the width of the output. -x Treat unknown capabilities as user-defined. That is, if you supply a capability name which tic does not recog- nize, it will infer its type (boolean, number or string) from the syntax and make an extended table entry for that. User-defined capability strings whose name begins with ``k'' are treated as function keys. file contains one or more terminfo terminal descriptions in source format [see terminfo(5)]. Each description in the file describes the capabilities of a particular terminal. The debug flag levels are as follows: 1 Names of files created and linked MirOS BSD #10-current Printed 4.7.2014 3 tic(1) UNIX Programmer's Manual tic(1) 2 Information related to the ``use'' facility 3 Statistics from the hashing algorithm 5 String-table memory allocations 7 Entries into the string-table 8 List of tokens encountered by scanner 9 All values computed in construction of the hash table If the debug level n is not given, it is taken to be one. All but one of the capabilities recognized by tic are docu- mented in terminfo(5). The exception is the use capability. When a use=entry-name field is discovered in a terminal entry currently being compiled, tic reads in the binary from /usr/share/terminfo to complete the entry. (Entries created from file will be used first. If the environment variable TERMINFO is set, that directory is searched instead of /usr/share/terminfo.) tic duplicates the capabilities in entry-name for the current entry, with the exception of those capabilities that explicitly are defined in the current entry. When an entry, e.g., entry_name_1, contains a use=entry_name_2 field, any canceled capabilities in entry_name_2 must also appear in entry_name_1 before use= for these capabilities to be canceled in entry_name_1. If the environment variable TERMINFO is set, the compiled results are placed there instead of /usr/share/terminfo. Total compiled entries cannot exceed 4096 bytes. The name field cannot exceed 512 bytes. Terminal names exceeding the maximum alias length (32 characters on systems with long filenames, 14 characters otherwise) will be truncated to the maximum alias length and a warning message will be printed.
There is some evidence that historic tic implementations treated description fields with no whitespace in them as additional aliases or short names. This tic does not do that, but it does warn when description fields may be treated that way and check them for dangerous characters.
Unlike the stock SVr4 tic command, this implementation can actually compile termcap sources. In fact, entries in ter- minfo and termcap syntax can be mixed in a single source MirOS BSD #10-current Printed 4.7.2014 4 tic(1) UNIX Programmer's Manual tic(1) file. See terminfo(5) for the list of termcap names taken to be equivalent to terminfo names. The SVr4 manual pages are not clear on the resolution rules for use capabilities. This implementation of tic will find use targets anywhere in the source file, or anywhere in the file tree rooted at TERMINFO (if TERMINFO is defined), or in the user's $HOME/.terminfo directory (if it exists), or (finally) anywhere in the system's file tree of compiled entries. The error messages from this tic have the same format as GNU C error messages, and can be parsed by GNU Emacs's compile facility. The -C, -G, -I, -N, -R, -T, -V, -a, -e, -f, -g, -o, -r, -s, -t and -x options are not supported under SVr4. The SVr4 -c mode does not report bad use links. System V does not compile entries to or read entries from your $HOME/.terminfo directory unless TERMINFO is explicitly set to it.
