<STRONG>infocmp</STRONG> can be used to compare a binary <STRONG>terminfo</STRONG> entry with other
terminfo entries, rewrite a <STRONG>terminfo</STRONG> description to take advantage of
the <STRONG>use=</STRONG> terminfo field, or print out a <STRONG>terminfo</STRONG> description from the
binary file (<STRONG>term</STRONG>) in a variety of formats. In all cases, the Boolean
fields will be printed first, followed by the numeric fields, followed
by the string fields.
</PRE><H3><a name="h3-Default-Options">Default Options</a></H3><PRE>
If no options are specified and zero or one <EM>terminal-types</EM> are
specified, the <STRONG>-I</STRONG> option will be assumed. If more than one <EM>terminal-</EM>
<EM>type</EM> is specified, the <STRONG>-d</STRONG> option will be assumed.
</PRE><H3><a name="h3-Comparison-Options_d_c_n_">Comparison Options [-d] [-c] [-n]</a></H3><PRE>
<STRONG>infocmp</STRONG> compares the <STRONG>terminfo</STRONG> description of the first terminal
<EM>terminal-type</EM> with each of the descriptions given by the entries for
the other terminal's <EM>terminal-types</EM>. If a capability is defined for
only one of the terminals, the value returned depends on the type of
the capability:
<STRONG>o</STRONG> <STRONG>F</STRONG> for missing Boolean variables
<STRONG>o</STRONG> <STRONG>NULL</STRONG> for missing integer or string variables
Use the <STRONG>-q</STRONG> option to show the distinction between <EM>absent</EM> and <EM>cancelled</EM>
capabilities.
These options produce a list which you can use to compare two or more
terminal descriptions:
<STRONG>-d</STRONG> produces a list of each capability that is <EM>different</EM> between two
entries. Each item in the list shows ":" after the capability
name, followed by the capability values, separated by a comma.
<STRONG>-c</STRONG> produces a list of each capability that is <EM>common</EM> between two or
more entries. Missing capabilities are ignored. Each item in the
list shows "=" after the capability name, followed by the
capability value.
The <STRONG>-u</STRONG> option provides a related output, showing the first
terminal description rewritten to use the second as a building
block via the "use=" clause.
<STRONG>-n</STRONG> produces a list of each capability that is in <EM>none</EM> of the given
entries. Each item in the list shows "!" before the capability
name.
Normally only the conventional capabilities are shown. Use the <STRONG>-x</STRONG>
option to add the BSD-compatibility capabilities (names prefixed
with "OT").
If no <EM>terminal-types</EM> are given, <STRONG>infocmp</STRONG> uses the environment
variable <EM>TERM</EM> for each of the <EM>terminal-types</EM>.
</PRE><H3><a name="h3-Source-Listing-Options_I_L_C_r_">Source Listing Options [-I] [-L] [-C] [-r]</a></H3><PRE>
The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will produce a source listing for each
terminal named.
<STRONG>-I</STRONG> use <EM>terminfo</EM> capability codes
<STRONG>-L</STRONG> use "long" capability names
<STRONG>-C</STRONG> use <EM>termcap</EM> capability codes
<STRONG>-r</STRONG> with <STRONG>-C</STRONG>, include nonstandard capabilities
<STRONG>-K</STRONG> with <STRONG>-C</STRONG>, improve BSD compatibility
If no <EM>terminal-types</EM> are given, the environment variable <EM>TERM</EM> will be
used for the terminal name.
The source produced by the <STRONG>-C</STRONG> option may be used directly as a <STRONG>termcap</STRONG>
entry, but not all parameterized strings can be changed to the <STRONG>termcap</STRONG>
format. <STRONG>infocmp</STRONG> will attempt to convert most of the parameterized
information, and anything not converted will be plainly marked in the
output and commented out. These should be edited by hand.
For best results when converting to <STRONG>termcap</STRONG> format, you should use both
<STRONG>-C</STRONG> and <STRONG>-r</STRONG>. Normally a termcap description is limited to 1023 bytes.
<STRONG>infocmp</STRONG> trims away less essential parts to make it fit. If you are
converting to one of the (rare) termcap implementations which accept an
unlimited size of termcap, you may want to add the <STRONG>-T</STRONG> option. More
often however, you must help the termcap implementation, and trim
excess whitespace (use the <STRONG>-0</STRONG> option for that).
All padding information for strings will be collected together and
placed at the beginning of the string where <STRONG>termcap</STRONG> expects it.
Mandatory padding (padding information with a trailing "/") will become
optional.
All <STRONG>termcap</STRONG> variables no longer supported by <STRONG>terminfo</STRONG>, but which are
derivable from other <STRONG>terminfo</STRONG> variables, will be output. Not all
<STRONG>terminfo</STRONG> capabilities will be translated; only those variables which
were part of <STRONG>termcap</STRONG> will normally be output. Specifying the <STRONG>-r</STRONG> option
will take off this restriction, allowing all capabilities to be output
in <EM>termcap</EM> form. Normally you would use both the <STRONG>-C</STRONG> and <STRONG>-r</STRONG> options.
The actual format used incorporates some improvements for escaped
characters from terminfo format. For a stricter BSD-compatible
translation, use the <STRONG>-K</STRONG> option rather than <STRONG>-C</STRONG>.
Note that because padding is collected to the beginning of the
capability, not all capabilities are output. Mandatory padding is not
supported. Because <STRONG>termcap</STRONG> strings are not as flexible, it is not
always possible to convert a <STRONG>terminfo</STRONG> string capability into an
equivalent <STRONG>termcap</STRONG> format. A subsequent conversion of the <STRONG>termcap</STRONG> file
back into <STRONG>terminfo</STRONG> format will not necessarily reproduce the original
<STRONG>terminfo</STRONG> source.
Some common <STRONG>terminfo</STRONG> parameter sequences, their <STRONG>termcap</STRONG> equivalents,
and some terminal types which commonly have such sequences, are:
<STRONG><EM>terminfo</EM></STRONG> <STRONG><EM>termcap</EM></STRONG> Terminal Types

</PRE><H3><a name="h3-Use_Option_u_">Use= Option [-u]</a></H3><PRE>
The <STRONG>-u</STRONG> option produces a <STRONG>terminfo</STRONG> source description of the first
terminal <EM>terminal-type</EM> which is relative to the sum of the descriptions
given by the entries for the other <EM>terminal-types</EM>. It does this by
analyzing the differences between the first <EM>terminal-types</EM> and the
other <EM>terminal-types</EM> and producing a description with <STRONG>use=</STRONG> fields for
the other terminals. In this manner, it is possible to retrofit
generic terminfo entries into a terminal's description. Or, if two
similar terminals exist, but were coded at different times or by
different people so that each description is a full description, using
<STRONG>infocmp</STRONG> will show what can be done to change one description to be
relative to the other.
A capability will be printed with an at-sign (@) if it no longer exists
in the first <EM>terminal-type</EM>, but one of the other <EM>terminal-type</EM> entries
contains a value for it. A capability's value will be printed if the
value in the first <EM>terminal-type</EM> is not found in any of the other
<EM>terminal-type</EM> entries, or if the first of the other <EM>terminal-type</EM>
entries that has this capability gives a different value for the
capability than that in the first <EM>terminal-type</EM>.
The order of the other <EM>terminal-type</EM> entries is significant. Since the
terminfo compiler <STRONG>tic</STRONG> does a left-to-right scan of the capabilities,
specifying two <STRONG>use=</STRONG> entries that contain differing entries for the same
capabilities will produce different results depending on the order that
the entries are given in. <STRONG>infocmp</STRONG> will flag any such inconsistencies
between the other <EM>terminal-type</EM> entries as they are found.
Alternatively, specifying a capability <EM>after</EM> a <STRONG>use=</STRONG> entry that contains
that capability will cause the second specification to be ignored.
Using <STRONG>infocmp</STRONG> to recreate a description can be a useful check to make
sure that everything was specified correctly in the original source
description.
Another error that does not cause incorrect compiled files, but will
slow down the compilation time, is specifying extra <STRONG>use=</STRONG> fields that
are superfluous. <STRONG>infocmp</STRONG> will flag any other <EM>terminal-type</EM> <EM>use=</EM> fields
that were not needed.
<STRONG>Changing</STRONG> <STRONG>Databases</STRONG> <STRONG>[-A</STRONG> <EM>directory</EM>] [-B <EM>directory</EM>]
Like other <EM>ncurses</EM> utilities, <STRONG>infocmp</STRONG> looks for the terminal
descriptions in several places. You can use the <EM>TERMINFO</EM> and
<EM>TERMINFO</EM><STRONG>_</STRONG><EM>DIRS</EM> environment variables to override the compiled-in default
list of places to search. See <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, as well as the <EM>Fetching</EM>
<EM>Compiled</EM> <EM>Descriptions</EM> section in <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
You can also use the options <STRONG>-A</STRONG> and <STRONG>-B</STRONG> to override the list of places
to search when comparing terminal descriptions:
<STRONG>o</STRONG> The <STRONG>-A</STRONG> option sets the location for the first <EM>terminal-type</EM>
<STRONG>o</STRONG> The <STRONG>-B</STRONG> option sets the location for the other <EM>terminal-types</EM>.
Using these options, it is possible to compare descriptions for a
terminal with the same name located in two different databases. For
instance, you can use this feature for comparing descriptions for the
same terminal created by different people.
</PRE><H3><a name="h3-Other-Options">Other Options</a></H3><PRE>
<STRONG>-0</STRONG> causes the fields to be printed on one line, without wrapping.
<STRONG>-1</STRONG> causes the fields to be printed out one to a line. Otherwise, the
fields will be printed several to a line to a maximum width of 60
characters.
<STRONG>-a</STRONG> tells <STRONG>infocmp</STRONG> to retain commented-out capabilities rather than
discarding them. Capabilities are commented by prefixing them
with a period.
<STRONG>-D</STRONG> tells <STRONG>infocmp</STRONG> to print the database locations that it knows about,
and exit.
<STRONG>-E</STRONG> Dump the capabilities of the given terminal as tables, needed in
the C initializer for a TERMTYPE structure (the terminal
capability structure in the <STRONG><term.h></STRONG>). This option is useful for
preparing versions of the curses library hardwired for a given
terminal type. The tables are all declared static, and are named
according to the type and the name of the corresponding terminal
entry.
Before <EM>ncurses</EM> 5.0, the split between the <STRONG>-e</STRONG> and <STRONG>-E</STRONG> options was
not needed; but support for extended names required making the
arrays of terminal capabilities separate from the TERMTYPE
structure.
<STRONG>-e</STRONG> Dump the capabilities of the given terminal as a C initializer for
a TERMTYPE structure (the terminal capability structure in the
<STRONG><term.h></STRONG>). This option is useful for preparing versions of the
curses library hardwired for a given terminal type.
<STRONG>-F</STRONG> compare terminfo files. This assumes that two following arguments
are filenames. The files are searched for pairwise matches
between entries, with two entries considered to match if any of
their names do. The report printed to standard output lists
entries with no matches in the other file, and entries with more
than one match. For entries with exactly one match it includes a
difference report. Normally, to reduce the volume of the report,
use references are not resolved before looking for differences,
but resolution can be forced by also specifying <STRONG>-r</STRONG>.
<STRONG>-f</STRONG> Display complex terminfo strings which contain if/then/else/endif
expressions indented for readability.
<STRONG>-G</STRONG> Display constant literals in decimal form rather than their
character equivalents.
<STRONG>-g</STRONG> Display constant character literals in quoted form rather than
their decimal equivalents.
<STRONG>-i</STRONG> Analyze the initialization (<STRONG>is1</STRONG>, <STRONG>is2</STRONG>, <STRONG>is3</STRONG>), and reset (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>,
<STRONG>rs3</STRONG>), strings in the entry, as well as those used for
starting/stopping cursor-positioning mode (<STRONG>smcup</STRONG>, <STRONG>rmcup</STRONG>) as well
as starting/stopping keymap mode (<STRONG>smkx</STRONG>, <STRONG>rmkx</STRONG>).
For each string, the code tries to analyze it into actions in
terms of the other capabilities in the entry, certain X3.64/ISO
6429/ECMA-48 capabilities, and certain DEC VT-series private modes
(the set of recognized special sequences has been selected for
completeness over the existing terminfo database). Each report
line consists of the capability name, followed by a colon and
space, followed by a printable expansion of the capability string
with sections matching recognized actions translated into
{}-bracketed descriptions.
Here is a list of the DEC/ANSI special sequences recognized:
Action Meaning
-----------------------------------------
RIS full reset
SC save cursor

It also recognizes a SGR action corresponding to ANSI/ISO 6429/ECMA Set
Graphics Rendition, with the values NORMAL, BOLD, UNDERLINE, BLINK, and
REVERSE. All but NORMAL may be prefixed with
<STRONG>o</STRONG> "+" (turn on) or
<STRONG>o</STRONG> "-" (turn off).
An SGR0 designates an empty highlight sequence (equivalent to
{SGR:NORMAL}).
<STRONG>-l</STRONG> Set output format to terminfo.
<STRONG>-p</STRONG> Ignore padding specifications when comparing strings.
<STRONG>-Q</STRONG> <EM>n</EM> Rather than show source in terminfo (text) format, print the
compiled (binary) format in hexadecimal or base64 form, depending
on the option's value:
1 hexadecimal
2 base64
3 hexadecimal and base64
For example, this prints the compiled terminfo value as a string
which could be assigned to the <EM>TERMINFO</EM> environment variable:
infocmp -0 -q -Q2
<STRONG>-q</STRONG> This makes the output a little shorter:
<STRONG>o</STRONG> Make the comparison listing shorter by omitting subheadings,
and using "-" for absent capabilities, "@" for canceled rather
than "NULL".
<STRONG>o</STRONG> However, show differences between absent and cancelled
capabilities.
<STRONG>o</STRONG> Omit the "Reconstructed from" comment for source listings.
<STRONG>-R</STRONG><EM>subset</EM>
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
variants such as AIX that have their own extensions incompatible
with SVr4/XSI.
<STRONG>o</STRONG> Available terminfo subsets are "SVr1", "Ultrix", "HP", and
"AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for details.
<STRONG>o</STRONG> You can also choose the subset "BSD" which selects only
capabilities with termcap equivalents recognized by 4.4BSD.
<STRONG>o</STRONG> If you select any other value for <STRONG>-R</STRONG>, it is the same as no
subset, i.e., all capabilities are used.
A few options override the subset selected with <STRONG>-R</STRONG>, if they are
processed later in the command parameters:
<STRONG>-C</STRONG> sets the "BSD" subset as a side-effect.
<STRONG>-I</STRONG> sets the subset to all capabilities.
<STRONG>-r</STRONG> sets the subset to all capabilities.
<STRONG>-s</STRONG> <EM>[d|i|l|c]</EM>
The <STRONG>-s</STRONG> option sorts the fields within each type according to the
argument below:
<STRONG>d</STRONG> leave fields in the order that they are stored in the
<EM>terminfo</EM> database.
<STRONG>i</STRONG> sort by <EM>terminfo</EM> name.
<STRONG>l</STRONG> sort by the long C variable name.
<STRONG>c</STRONG> sort by the <EM>termcap</EM> name.
If the <STRONG>-s</STRONG> option is not given, the fields printed out will be
sorted alphabetically by the <STRONG>terminfo</STRONG> name within each type,
except in the case of the <STRONG>-C</STRONG> or the <STRONG>-L</STRONG> options, which cause the
sorting to be done by the <STRONG>termcap</STRONG> name or the long C variable
name, respectively.
<STRONG>-T</STRONG> 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).
<STRONG>-t</STRONG> tells <STRONG>tic</STRONG> to discard commented-out capabilities. Normally when
translating from terminfo to termcap, untranslatable capabilities
are commented-out.
<STRONG>-U</STRONG> tells <STRONG>infocmp</STRONG> to not post-process the data after parsing the
source file. This feature helps when comparing the actual
contents of two source files, since it excludes the inferences
that <STRONG>infocmp</STRONG> makes to fill in missing data.
<STRONG>-V</STRONG> reports the version of <EM>ncurses</EM> which was used in this program, and
exits.
<STRONG>-v</STRONG> <EM>n</EM> prints out tracing information on standard error as the program
runs.
The optional parameter <EM>n</EM> is a number from 1 to 10, inclusive,
indicating the desired level of detail of information. If <EM>ncurses</EM>
is built without tracing support, the optional parameter is
ignored.
<STRONG>-W</STRONG> By itself, the <STRONG>-w</STRONG> option will not force long strings to be
wrapped. Use the <STRONG>-W</STRONG> option to do this.
<STRONG>-w</STRONG> <EM>width</EM>
changes the output to <EM>width</EM> characters.
<STRONG>-x</STRONG> print information for user-defined capabilities (see <STRONG><A HREF="user_caps.5.html">user_caps(5)</A></STRONG>.
These are extensions to the terminfo repertoire which can be
loaded using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>.

and <STRONG>-t</STRONG> options are not supported in SVr4 curses.
SVr4 infocmp does not distinguish between absent and cancelled
capabilities. Also, it shows missing integer capabilities as <STRONG>-1</STRONG> (the
internal value used to represent missing integers). This
implementation shows those as "NULL", for consistency with missing
strings.
The <STRONG>-r</STRONG> option's notion of "termcap" capabilities is System V Release
4's. Actual BSD curses versions will have a more restricted set. To
see only the 4.4BSD set, use <STRONG>-r</STRONG> <STRONG>-RBSD</STRONG>.

X/Open Curses, Issue 7 (2009) provides a description of <STRONG>infocmp</STRONG>. It
does not mention the options used for converting to termcap format.

Although System V Release 2 provided a terminfo library, it had no
documented tool for decompiling the terminal descriptions. Tony Hansen
(AT&T) wrote the first <STRONG>infocmp</STRONG> in early 1984, for System V Release 3.
Eric Raymond used the AT&T documentation in 1995 to provide an
equivalent <STRONG>infocmp</STRONG> for <EM>ncurses</EM>. In addition, he added a few new
features such as:
<STRONG>o</STRONG> the <STRONG>-e</STRONG> option, to support <EM>fallback</EM> (compiled-in) terminal
descriptions
<STRONG>o</STRONG> the <STRONG>-i</STRONG> option, to help with analysis
Later, Thomas Dickey added the <STRONG>-x</STRONG> (user-defined capabilities) option,
and the <STRONG>-E</STRONG> option to support fallback entries with user-defined
capabilities.
For a complete list, see the <EM>EXTENSIONS</EM> section.
In 2010, Roy Marples provided an <STRONG>infocmp</STRONG> program for NetBSD. It is
less capable than the SVr4 or <EM>ncurses</EM> versions (e.g., it lacks the
sorting options documented in X/Open), but does include the <STRONG>-x</STRONG> option
adapted from <EM>ncurses</EM>.
