- Even better. I have a patch for termcap.c that will solve the problem:
-
- - it deletes capabilities that start with '.' as used in the new
- termcap files - those are commented out capabilities.
- - it tries to translate escaped characters before putting them
- in the buffer as opposed to doing at in tgetstr.
-
- Now the Linux and other entries fit in 1024 bytes.

- I copied the termcap info stuff as well as termcap.src from
- the GNU termcap 1.3. But I didn't copy the source code. The
- Linux termcap 2.0.7 is different from the GNU termcap 1.3. But
- they share the same API/ABI. The linux entry in the new termcap
- is larger than 1024 chars. But your application may only have
- a 1024 byte buffer. You may see
-
- tgetent: warning: termcap entry too long
-
- message when you run it in the Linux console. You can pass NULL to
- tgetent () to let termcap malloc the buffer. elm and zsh are two
- applications I know which use termcap and have this problem.

- ----
- I decided to reissue libtermcap and make it ELF only since ncurses
- is an overkill for termcap. You need to install binutils 2.6.0.2 or
- above, gcc 2.7.2 or above and libc 5.2.18 or above to compile/install
- this termcap library. There are no code changes from libtermcap 2.0.3
- which was included in libc 5.0.9 last time.

- -----
- This is the new termcap library for Linux. It consists of
- two source files:
-
- 1. termcap.c - written form scratch by me
- 2. tparam.c - this is the the GNU emacs or glibc tparam.c
-
- The new tgetent in termcap.c checks for overflow of the
- termcap buffer, which most applications assume is 1024 characters.
- Furthermore it eliminates duplicate entries and checks for
- loops caused by the include capability "tc=".
-
- The termcap.c code falls under the LGPL.
- (Library version of GNU Public License).
-
- If you create termcap files with many levels of indirection
- (with the tc= variable) this code will work allright, but the
- internal buffer of software that uses it's own tgetent() function
- will probably overflow, if it even supports "tc". It is therefore
- always a good idea to include a "eval `tset -s $TERM`" in your
- /etc/profile (assuming that tset uses the new termcap library!),
- because that initializes the TERMCAP variable. The whole, small
- termcap entry will then be stored in TERMCAP. Most if not all
- tgetent() implementations check for a TERMCAP environment variable
- first before searching /etc/termcap.

- The original README and NEWS files are included below.
-
- ========== Original README ===========
-
- This is the GNU termcap library -- a library of C functions that
- enable programs to send control strings to terminals in a way
- independent of the terminal type. Most of this package is also
- distributed with GNU Emacs, but it is available in this separate
- distribution to make it easier to install as -ltermcap.
-
- The GNU termcap library does not place an arbitrary limit on the size
- of termcap entries, unlike most other termcap libraries.
-
- See the file INSTALL for compilation and installation instructions.
-
- Please report any bugs in this library to bug-gnu-emacs@prep.ai.mit.edu.
- You can check which version of the library you have by using the RCS
- `ident' command on libtermcap.a.
-
- =========== Original NEWS ===========
