________________________________________________________________
* release of groffer 0.9.22
2005-22-04 Bernd Warken
### `--whatis'
Produce a `groff' output and allow wild cards on filespec
parameters for `--whatis'.
* groffer2.sh:
- $_FILESPEC_ARG: New variable for storing the actual filespec
parameter.
- main_do_fileargs(): Set $_FILESPEC_ARG and add
what_is_filespec().
- main_parse_args(): Add --all to --whatis.
- to_tmp_line(): New function to write the arguments to the
temorary cat file.
- whatis_filename(): Rename of what_is(). Construct a better
printout using $_FILESPEC_ARG. Repair the sed sequneces.
- whatis_filespec(): New function to print the filespec once
during the `whatis' process.
- whatis_header(): New funtion for printing the header of the
`whatis' output.
* groffer.man: Revise the documentation of --whatis.
### `--apropos*'
Produce `groff' for `--apropos*'. Allow `--sections' for
`--apropos', ignore it with `--apropos-*'.
* groffer2.sh:
- --apropos*: Make these options without argument.
- $_APROPOS_PROG: New variable for the program that is is used for
`apropos'.
- $_APROPOS_SECTIONS: New variable to determine the sections that
are filtered out of `apropos' output depending on `--apropos-*'.
- apropos_filespec(): Handling of apropos at the filespec level.
- apropos_run(): Remove it.
- apropos_setup(): New function.
- main_set_mode(): Remove handling of $_OPT_APROPOS*.
* groffer.man:
- Revise the documentation of `--apropos*'.
- Split section 'options for GNU man' into two sections `options
for man pages' and `long options taken over from GNU man'.
- Move `--apropos*', `--whatis', `--man', and `--no-man' to
section `options for man pages'.
### special display (apropos and whatis)
* groffer2.sh:
- special_setup(): New function that chooses the setup between
apropos and whatis.
- special_filespec(): New function that does the output at the
filespec level for apropos or whatis.
### handle `--sections' for man page searching
* groffer2.sh:
- man_do_filespec(): Use $_OPT_SECTIONS of --sections instead of
$_MAN_AUTO_SEC if non-empty. If a section was given on the
filespec parameter $_OPT_SECTIONS is ignored. This differs from
`man' which always uses the restricted sections of --sections.
This function works for both normal man page search and whatis.
- apropos_filespec(): Use --sections for --apropos, but not for
--apropos-* because these provide already their own sections.
### wildcards in filespec arguments
* groffer2.sh: Wildcards are now accepted. In `--apropos*' and
`--whatis' they are interpreted as wildcard search elements; but
in normal display they are only handled as their own character.
### development; new option
* groffer2.sh:
- --print: New option that prints just its argument for parameter
check.
- usage(): Add new option.
- $_OPT_DO_NOTHING: New variable for do_nothing(). Handle it at
the end of main_parse_Args().
* groffer.man: Add information on --print.
### safe exit
* groffer2.sh:
- error(): Always exit with $_ERROR.
- exit_test(): New function to exit when first exit was hidden by
(). Call it after each $().
### automatic shell determination
* groffer.sh:
- If no option --shell is given perform a test of several shells
to automatically start some shell for groffer2.sh. `ksh' is used
first because it can be safely terminated by Ctrl-C.
- This can be cancelled by providing --shell=''.
- Add test on `sed' program.
* groffer.man: Revise information on --shell.
### trap
* groffer2.sh:
- trap_set(): Remove argument. Instead of $_ALL_EXIT use only
signal 0.
- trap_unset(): Rename trap_clean(). Instead of $_ALL_EXIT use
only signal 0.
- $_ALL_EXIT: Remove this variable.
- Replace all direct `trap' calls by trap_set().
* README_SH: New section `Bugs' on `trap'..
### user errors, error output without function stack
* groffer2.sh:
- error_user(): New function for user errors.
- error(): Remove call of clean_up() because the trap will do it
with the exit. Remove the `kill' commands. Create a temporary
file `.error' that can be tested by exit_test() for a better exit
test (especially for shell `ksh').
- $_DEBUG_USER_WITH_STACK: New variable to enable function stack
output in error_user().
- list_from_cmdline(), list_single_from_abbrev(), main_set_mode():
Use error_user().
### test modes on X and tty
* groffer2,sh:
- is_X(), is_not_X(): New functions for checking on X Window.
- $_VIEWER_HTML_TTY, $_VIEWER_HTML_X: New variables that split
$_VIEWER_HTML. Add `galeon'.
- main_parse_args(): Allow mode change for graphical modes only
when in X Window.
- _do_display() of main_display(): Create a special run for
viewers that run on the terminal; `lynx' is the only one so far.
### add $GROFFER_MODE to command line
* groffer.sh:
- After the handling of the configuration files integrate
$GROFFER_OPT to the command line.
- This makes a `set' in the shell determination unnecessary.
* groffer2.sh:
- The debug test gets simpler because quotes are vanished without
$GROFFER_OPT.
- main_parse_MANOPT(): Prepend $mpm_list to the command line.
- main_parse_args(): `set' is unnecessary.
### debug; new options
* groffer2.sh:
- --debug-all, --debug-lm, --debug-params, --debug-shell,
--debug-stacks, --debug-tmpdir, --debug-user: New options.
- --debug: Enable all debug variables except $_DEBUG_STACKS and
$_DEBUG_LM. By the new options the smallest abbreviation is now
`--debug'.
- $_DEBUG_STACKS: Rename $_DEBUG.
- $_DEBUG_PRINT_TMPDIR: New debug variable for printing the name
of the temporary directory in main_init().
- $_OPT_DEBUG: Remove this variable because debug is handled at
the early part of the script.
- clean_up(): Enlarge $_DEBUG_KEEP_FILES to not deleting the
temporary directory.
- usage(): Move all development options on a section of its own.
- Move the test of rudimentary shell functionality at the
beginning of the script. Add test on `sed'.
- Follow this by the debug section. The determination of all
--debug* options can be done without a function.
* groffer.man: Revise information on --debug and add new options.
### variables
* groffer.sh:
- $_ERROR: Move the definition of this variable here.
- $_GROFF_VERSION: New variable, is set over @...@ construct.
- $_OUTPUT_FILE_NAME: Move this variable to groffer2.sh.
* groffer2.sh:
- $_MAN_AUTO_SEC_LIST: Rename $_MAN_AUTO_SEC because it represents
a list.
- $_MAN_AUTO_SEC_CHARS: New read-only variable for storing
$_MAN_AUTO_SEC_LIST in [] construct. Use it in man_do_filespec()
and whatis_filename().
- $_SPACE_CASE: New read-only variable with [] on space characters
with \ for `case' patterns. Use it in several functions.
- $_SPACE_SED: New read-only variable with [] on space characters
for `sed'. Use it in several functions.
### options and display
* groffer2.sh:
- list_from_cmdline(): Add test whether the same abbreviation is
part of long options with and without arguments. Give handling of
`=' a `case' pattern of its own.
- main_display(): Remove unnecessary calls of `clean_up' in order
to use `mozilla' without problems. In _do_display(): Fix -X by
providing a different process when $_DISPLAY_PROG is empty.
- main_set_mode(): Accept options for viewers as is, without check
for program. Add test whether no program is given for a mode.
This avoids unnecessary empty $_DISPLAY_PROG in main_display().
### viewer programs that run on the terminal (tty); new options
* groffer2.sh:
- $_VIEWER_TERMINAL: New variable that stores whether a viewer was
supposed to run on tty.
- --dvi-viewer-tty, --html-viewer-tty, --pdf-viewer-tty,
--ps-viewer-tty, --tty-viewer-tty, --X-viewer-tty, --x-viewer-tty,
--www-viewer-tty: New options for viewers that run on a terminal.
- main_parse_args(), _do_display() of main_display(): Use the new
options and the new variable.
- usage(): Add the new options.
* groffer.man: Add information on options --*-viewer-tty.
### other fixes
* groffer2.sh:
- _do_display() of main_display(): Bear errors of `groff' run.
- is_not_file: Fix to have exactly one argument.
- is_not_prog(): Handle no arguments.
- list_has_not(): Fix.
- main_do_fileargs(): Remove $mdfa_exitcode.
- register_title(): Limit title to 4 elements.
- version(): Print the version information to standard output just
like `groff' does.
- --no-special: New option to disable former calls of `--all',
`--apropos*', and `whatis.
- --title: Make it an option with argument.
2005-08-07 Keith Marshall <keith.d.marshall@ntlworld.com>
* contrib/groffer/Makefile.sub (install): Reference groffer2.sh
as $(srcdir)/groffer2.sh, so it will install when building in a
different directory from the source.
________________________________________________________________
* release of groffer 0.9.21
2005-08-02 Bernd Warken
### @...@ constructs
* groffer.sh:
- $_AT: New variable for `@'.
- @...@: Replace the @...@ constructs by variables _AT_..._AT.
These constructs are transformed by `make' to useful information.
Keep all of these constructs in the first part of groffer.sh. For
a run before a `make' call, the script sets these variables to
special values for testing purpose.
- $_GROFFER_LIBDIR: Variable pointing to the groffer library
directory @libdir@/groff/groffer.
### Configuration files
* groffer.sh:
- Add test for `$()' construct.
- Read and transform the configuration files and execute the
emerging commands. The `sed' script was heavily enlarged to
handle line with spaces and quotes. The emerging script is now
called by `eval', so no temporary file is needed.
- $_CONF_FILE_ETC, $_CONF_FILE_HOME: New variables for the config
files.
- $_SQ, $_SP: Move variables for characters before the handling of
the configuration files. Rename $_SQUOTE to $_SQ and $_SPACE to
$_SP.
- $GROFFER_OPT: Remove cleaning of this variable before the
reading of the configuration files.
* groffer2.sh:
- main_init(): Remove the getting of the configuration files.
### Rewrite the shell determination
* groffer.sh:
- Get rid of all functions in `groffer.sh'. Rewrite the shell
determination with `` and $().
- --shell: Shortest abbreviation is `--sh'. Allow arguments for
the shell name.
- Allow an empty argument for --shell as shell name to overwrite a
specified shell; an empty shell name gets back to the default
shell.
- The shell determination now inludes the full handling of the
config files. The `--shell' option needs no longer a line
starting with `-'.
### Test of unset
* groffer.sh:
- Remove test of `unset'.
- Remove all calls of `unset'.
- Use one character names for all variables that are meant to be
local in this script.
* groffer2.sh:
- Move the test of `unset' to the testing of rudimentary shell
functionality without change.
### Allow abbreviations for long options
* groffer2.sh:
- list_has_abbrev(): New function for checking a list having an
element with a given abbreviation.
- list_get_single_from_abbrev(): New function to retrieve the
element having a given abbreviation.
- list_from_cmd_line(): For an option abbreviation determine the
corresponding long option.
- From the man option lists remove the elements that are also in
a groffer list.
- Allow abbreviation for the early test of --debug.
* groffer.sh: Allow abbreviation for the early test on --shell.
- get_opt_shell(): Rewrite _get_opt_shell() and the shell test
around it.
- test_on_shell(): Rename function _test_on_shell().
- $_SHELL: global variable for the shell to run groffer2.sh.
### Get rid of `sh -c'
* groffer2.sh:
- main_display(), _do_display(): Remove the `sh -c' calls. Make
the cleanup working without it.
- _do_display(): Extend _do_display() such that it can be used for
the pdf mode as well.
- _make_pdf(): New subfunction of main_display() for running the
additional parts of pdf mode in _do_display().
- rm_file(), rm_file_with_debug(), rm_tree(): New functions for
removing files and directories.
### Change directory
* groffer2.sh:
- $_START_DIR: New variable to store the directory at the starting
time of the script.
- main_display(): Go to the groffer temporary directory to be able
to process internal `groff' data like pictures.
- clean_up(): Get back to the starting directory.
### Compatibility with strange shells
* groffer2.sh:
- clean_up(): `zsh' and `posh' had difficulties with `eval'.
- is_*(): Add test on empty argument. Some shells return true on
`test -d' etc. with empty argument, while most shells return
false.
- echo1(); New function to print single line `cat <<EOF'. Replace
all `echo x' by `echo1'.
- list_has_abbrev(), list_from_cmdline(): Correction.
- main_parse_MANOPT(): Repair and revise.
- --do-nothing: New option without output (for development).
- Rewrite rudimentary shell functionality near the beginning of
the script.
* groffer.sh, groffer2.sh:
- Remove `;' after the commands `if', `while', and `until'.
### Debugging information
* groffer2.sh:
- $_DEBUG_PRINT_PARAMS: New variable for printing all parameters
from the config files, $GROFFER_OPT, and command line after they
have been transformed.
- $_DEBUG_PRINT_SHELL: New variable for printing the name of the
shell found in groff.sh.
- main(): Move the landmarks of main-*() into main().
### Further checks and additions
* groffer.sh, groffer2.sh:
- $_PROGRAM_NAME: Replace this variable by `groffer'. The program
name is now stable.
- $_GROFFER_RUN: Remove this variable. As `groffer.sh' or
`groffer' is no longer rerun, this variable is not necessary any
more.
* groffer2.sh:
- main_set_resources(): Make the default viewers capable to use
arguments in the list.
- leave(): Add an argument for given exit code. Use it where
suitable in main_*().
- do_filearg(): Add error messages for non-existing files and man
pages.
- _do_opt_V(): New subfunction of main_display() to handle the
output for option `-V'. `groff -V' is greatly enlarged by
`groffer' specific information.
- register_title(): Handle file names with spaces. Replace spaces
by `_'.
- is_existing(): Add `test -c' for special files.
- usage(): Add `=arg' to the options with an argument. Add option
`--tty-viewer'.
- kghostview: In the default viewer list, add option
`--scale=1.45'.
- $_OPTS_CMDLINE_SHORT_NA: Correct a lacking space.
* Makefile.sub: Repair the installation instructions for
groffer2.sh.
* groffer.man:
- Add paragraph on option handling.
- Add option `--do-nothing'.
- Reorder option for development and `groff'.
- Rewrite documentation for option `-V'.

groffer.sh. This script will be installed in the groffer library
directory @libdir@/groff/groffer, this might be
/usr/local/lib/groff/groffer/groffer2.sh for example.
* Makefile.sub:
- `groffer': Add replacement of @libdir@.
- `install_data': Add the installation of the groffer library
directory and groffer2.sh.
- `uninstall_sub': Delete the installed `groffer2.sh' and the
groffer library directory.

- Add argument options to the list of used commands.
- Documentation of the splitting of the script.
- Document the possible abbreviation of options.
________________________________________________________________
* release of groffer 0.9.19
2005-07-07 Bernd Warken
* groffer.sh: extensions
- `mode x': Mode for the equivalent options `--x', `--mode x',
`--X' `--mode X', and the default mode. The default assumes a
resolution of 75 dpi. The default device for a resolution of 75
dpi is `X75-12', the default device for a resolution of 100 dpi is
`X100'. The default geometry for the resolution of 100 dpi is set
to the width 800 dpi.
- `mode X': New mode for option -X only.
- `-V': Extent the `groff' output of -V by `groffer' specific
information (in main_display()).
- register_file(): Replace title `-' by `stdin'.
- $_DEBUG_KEEP_FILES: If set to `yes' the files in the temporary
directory are not deleted before the end trap.
* groffer.sh: get `zsh' to work as well
- tmp_create(): Use `: >file' for generating an empty file.
- rmdir: Replace `rmdir' by `rm -f -r'.
- eval: Add `eval' to many commands with variable arguments.
* groffer.sh: repair `debug'
- Print all debug output to stderr.
- $_FUNC_STACK: Built function call stack even when $_DEBUG is not
set. Now the arguments are not added.
- $_DEBUG: If set to `yes' print 3 call stack events: the function
that is added with its arguments is printed with `+++ '
(func_push()); the call stack after the addition is printed with
`>>> ' (func_push()); the call stack after the removing is printed
with `<<< ' (func_pop()).
- error(): Always print the function call stack on errors.
* groffer.sh: Corrections
- $_groffer_run: Rename to $_GROFFER_RUN.
- $unset: Rename to $_UNSET.
- Repair test of `unset'.
- Repair test for `--shell'. The script is now rerun under the
shell specified in the option argument. This can increase the
speed.
* README_SH: `zsh' now works.
* groffer.man:
- Reformulate the information for the `groffer' specific details
of option `-V'.
- Add information on the debug process.
- Add information on the default devices in `x mode'.
- Minor corrections.
________________________________________________________________
* release of groffer 0.9.18
2005-07-01 Bernd Warken
* groffer.sh: further shell compatibility
- `echo': Remove options and possible options of `echo' by
preceding the argument with a character `x' that is removed by
`sed' or replace `echo' by `cat <<EOF'. `echo -n' seems to be not
portable, so it is omitted.
- `for': Remove `;' from within `for' (because of ksh).
- `ls': Old UNIX systems echoed the error message to standard
output. So handle the output with `sed'. If the output contains
`not found' map it to an empty string.
- `true': Replace `true' by command `:'. Remove test of `true'
(because `ash' refuses the redefinition of builtins even in an
unreachable `if' branch).
- `false': Remove test of `false'; it isn't used any more.
- `test': As `test -e' does not exist in Solaris 2.5 replace it by
`test -f || test -d'.
- `unset': `unset' is said to be not portable. As `ash' protests
against the definition of the function `unset()' in the test of
`unset' replace the test by defining `$unset' to `unset' if it
exists and to `:' otherwise. Use `eval $unset' instead of the
direct command `unset'.
- _get_opt_shell(): Replace `for' loop with `shift' by `while'.
- man_search_section(): Replace `for f in filename*' by a test on
the existence of `filename*'.
- `zsh' interprets `$...' as `"$..."'. So `eval' must be called;
This cannot be used in `for i in $f', so it must be rewritten as
`for i in $(eval set x $f; shift; echo "$@")'
* groffer.sh:
- `--X', `--x', `--mode=X', `--mode=x': Make these options
equivalent to choosing an X device by setting `-TX75-12'. `-X' is
still equivalent to `groff -X'.
- main_init(): Choose the name of the temporary file by adding a
number using `expr' if it exists and cannot be removed.
- main_parse_args():Repair some options by replacing `$mpa_mode'
by `$_OPT_MODE'.
- catz(): Rename it to cat_z() to avoid problem with existing
programs.
- where(): Rename to where_is().
- $_CONFFILES: Rename to $_CONF_FILES.
- $_HAS_BZIP: export and preset it.
* groffer.man:
- Document the `X mode' changes.
- Add `@g@' to `troff'.
* README, README_SH, TODO:
- Add date line `Latest update:'.
- Add `...' quoting to essential terms.
- Add Emacs mode at the end.
* README_SH:
- Add documentation on the above compatibility changes.
- Add documentation on used commands.
- Mention the tested shells.
* Makefile.sub:
Readd `@g@'.

that is an abbreviation of the corresponding function name (quasi-
local variables).
- Unset the quasi-local function variables before returning.
- _t_e_s_t_f_u_n_c_(): Remove tests for local and global
variables.
- Add quasi-local variables for saving the content of
single-character variables.
- Remove some unused local and global variables.

made quasi-local.
* groffer.sh: other corrections
- $return_var: New function (after `eval') for an arbitrary
return value.
- obj*(): Add return modes.
- Rewrite tests for `true' and `false'.
- Add function names to error calls where it was forgotten.
- `for': Replace `for x in "$@"' by `for x'.
- `set': Replace `set -- ...' by `set x ...; shift'.
- `sed': Replace `\|.*|s|...|...|' by `s|...|...|'.
* README_SH:

* README_SH:
- Add compatibility information.
- Correct documentation for function arguments.
2005-06-18 Keith Marshall

* release of groffer 0.9.11
* groffer.sh:
- To the search of the `--apropos-*' options, add man pages with a
subsection in their apropos output.
2004-06-02 Bernd Warken
________________________________________________________________
* release of groffer 0.9.10
* groffer.sh:
- Remove automatic call of `ash' due to inconsistencies of
different ash versions.
- In the first run, add recognition of `--shell' lines in the
groffer configuration files. To configure an external shell in
a configuration file, a line starting with `--shell' is
necessary.
- list_from_cmdline(): Simplify the arguments.
- As $POSIXLY_CORRECT is internally set to `y' by some GNU
`/bin/sh' shells the following 2 fixes are necessary:
-- `sed': Empty patterns are not allowed with $POSIXLY_CORRECT
set; so move the address information before the `s' command to the
pattern after the command, and write `.*' to the address field.
-- list_from_cmdline(): Remove the strange $POSIXLY_CORRECT style
to finish the option processing after the first non-option
argument; use the flexible GNU mixing of options and file names
instead.
* groffer.man:
- Remove any hints on `ash'.
- Add minus line behavior of `--shell' for configuration and add a
corresponding example.
- Update the information on $POSIXLY_CORRECT.

________________________________________________________________
* release of groffer 0.9.5
This version is a rewrite of groffer in many parts, but it is kept
in the old single script style.
Overview of new options:
--text, --mode text, --tty-viewer,
--X, --mode X, --X-viewer, --html, --mode html, --html-view,
--apropos-data, --apropos-devel, --apropos-progs
New file:
<groffer-source>/README_SH
******* Extension of the `apropos' handling
The output of man's `apropos' has grown immensely meanwhile, so it
has become inefficient. Now `groffer' provides new options to get
the a selected information from this output.
* groffer.sh:
`--apropos-progs': new option for displaying only information
on programs (man page sections 1, 6, and 8)
`--apropos-data': new option for displaying only information
on documented data (man page sections 4, 5 and 7)
`--apropos-devel': new option for displaying only information
on development documentation (man page sections 2, 3 and 9)
`--apropos': still displays just the output of man's `apropos'
program.
- Specify all of these options as a single argument option; that
makes groffer's `--apropos' option slightly different because
the corresponding `man' option does not have arguments, but takes
all file arguments as apropos targets. So just ignore the `man'
options `-k' and `--apropos' in the parsing of $MANOPT.
- Exit after processing one `apropos' call.
******* Quasi object oriented function arguments
An object is the name of an environment variable. The value of
this variable contains the object's content. This allows to
specify function arguments and the calling syntax in a simpler way
by letting the first argument be a variable name, usable for input
or output.
Such an object type is `list', the string value of a shell
variable arranged in space-separated single-quoted elements, such
as $GROFFER_OPT internally.
* groffer.sh:
- Remove list_from_args(), list_element_from_arg()
list_from_lists(), list_length(), and list_prepend().
They can be replaced by list_append().
- All list*() functions are rearranged such that the first
argument is a list object, the name of a variable.
******* Simplification of configuration files
The new syntax of the groffer configuration files is
- all lines starting with a `-' character are interpreted as
command line options for all calls of groffer; they are collected
and prepended to the actual value of $GROFFER_OPT; optional
spaces at the beginning.of the line are omitted.
- all other lines are interpreted as a shell command and executed
in the current shell of the groffer call.
Precedence:
- The command line and the external environment variables such as
$GROFFER_OPT of the groffer call have the highest precedence.
- This is overwritten by the configuration file in the user's home
directory.
- The system configuration file in /etc has the lowest
precedence.
* groffer.sh:
The configuration files are now called after the determination of
the temporary files in main_init().
******* Script file name
The file name of the script is needed for the several calls during
the search for the optimal shell.
* groffer.sh:
- $_GROFFER_SH: replace $_this by $_GROFFER_SH and use $0 for
determining the file name of the script for the following calls,
instead of the cumbersome @BINDIR@ construction.
- Force the script to be called as an executable file, so $0 must
contain the program name.
******* Improved temporary file names
Just like groff, groffer mixes all file parameters into a single
output file. Its name is now constructed as a comma-separated
list built from the file name arguments without a leading comma.
So a leading comma can be used for the internal temporary file
names.
* groffer.sh:
- $_OUTPUT_FILE_NAME: new global variable as basis for the output
file name; it is set in main_set_resources().
- tmp_create(): use `,name' for temporary files different from
output file because the output file name does not start with a
comma. `$$' is not needed anymore.
- main_display(): simplification of $_modefile in _do_display()
and single display modes.
- Add extension `.html' to output file name in html mode.
- base_name(): correction for strange positions of `/'.
******* Mode fixes
* groffer.sh:
- Set the main default mode to `x' with groff's X Window viewer
`gxditview'.
- Allow 'x' and 'X' in `--mode' for the X Window mode; the same
for `--x' and `X', `--x-viewer' and `--X-viewer'.
- Make groff's `-X' equivalent to `mode X'.
- Fix `--auto', `--mode auto', and `--default-modes'.
- `html' mode: new mode equivalent to `www', add `konqueror' and
`lynx' as viewers.
- `pdf' mode: fix zoom options for pdf-viewer `xpdf' in
main_set_resources(); in main_display() fix the display structure.
- Set default X Window resolution to 75dpi. This is not optimal,
but with a higher value the options and resources for some viewers
must be optimized.
`--text' and `--mode text': new option for text output without a
pager.
- `--tty-viewer': new option equivalent to `--pager'.
- Correct the pagers for `tty' mode.
- Fix `groff' mode in main_set_resources() and main_display().
- Harmonize `--mode arg' with the equivalent options `--arg'.
******* Fixes for command line options
* groffer.sh:
- list_from_cmdline(): fix the parsing of options with arguments.
- Rename $_OPT_TTY_DEVICE to $_OPT_TEXT_DEVICE.
- $_OPTS_X_*: new variables for the inhereted X Window variables.
- Improve the distribution of the command line options into
$_OPTS_GROFFER_*, $_OPTS_GROFF_*, $_OPTS_X_*, and $_OPTS_MAN_*.
- $_OPTS_MANOPT_*: new variables for the parsing of $MANOPT.
- Correct $_OPTS_CMDLINE_*.
- Remove some unused $_OPTS_*.
- `--iconic': new option from `-iconic' of the X Window toolkit.
- Correct `--rv' to an option without argument.
- Minor fixes of other X Window toolkit options.
******* Other fixes
* groffer.sh:
- is_prog(): allow 0 arguments.
- is_not_writable(): new function.
- is_*(): fix trailing return codes.
- Replace most `test' calls by is_*() functions.
- man_setup(): due to bugs in `manpath', prefer
manpath_set_from_path() for the determination of the man page path.
- man_search_section(): correction of some `for' loops.
- Remove export of external non-groffer variables.
******* Documentation
* groffer.man:
- Reorder the option details according to the option origin as
groffer, groff, X, and man options.
- Add the programming changes information mentioned above.
- Support man pages with a dot in their name
* README_SH: new file
Move large parts of the documentation in `groffer.sh' into this
file.
* groffer.sh: usage():
- Change the output for `--help' to standard output.
- Restructure the information for this help output.
******* Removement of the author's email address
Because of the extreme spam attacks, the author removed all
occurencies of his email address in every file of the groffer
source.
2003-01-22 Bernd Warken
________________________________________________________________
* release of groffer 0.9.4
* groffer.sh: corrections for some restrictive shells
- Possible exit codes in actual `ash' are between 0 and 63. To
handle even deeper restrictions, use 7 as maximal code instead
of 255 as replacement for error -1.
- Remove variables $_BAD2 and $_BAD3.
- Replace `trap' argument `EXIT' by 0 and write new fuctions
`trap_clean' and `trap_set' to handle the restrictions of `trap'
for some shells.
- Correct wrong $MANPATH to $_MAN_PATH in function
`man_do_filespec'.
- Test existence of directory before deleting it in the
`clean_up' definitions.
- Correct help output in `usage' (called by `--help').
* TODO:
Remove mention of `shoop' and `apropos'.
2002-10-21 Bernd Warken
________________________________________________________________
* release of groffer 0.9.3
* groffer.sh: new temporary subdirectory
- Generate temporary subdirectory for storing temporary files
with better names in future groffer versions (name:
"groffer$$" in usual temporary directory).
- Use `umask 000' for temporary files to allow cleaning up
for everyone after a system break.
- Change both clean_up() functions (for normal shell and
for main_display() subshell) to handle the new subdirectory.
- clean_up_secondary() and $_TMP_PREFIX are unnecessary now, so
they were removed.
* Makefile.sub: `sed' commands for "groffer:"
- Remove "@g@" entry (not used in "groffer.sh").
- Add global replace for "@BINDIR@" and "@VERSION@" for future
usage.
* TODO: think about...

- Finish main_parse_MANOPT() if $MANOPT is empty.
- Sort $_OPTS_GROFF_SHORT_NA like groff short options (but
unchanged).
- Fix some comments.
* groffer.man: make it more readable (but no additions)

* TODO: remove done entries
- Remove request for different shells.
- Remove the 'sed' complaints.
2002-07-15 Bernd Warken
* groffer.sh: replace `sed' interface by direct `sed'
- This improves the performance of the shell programming parts
and shortens the groffer script by about 5%.
- Remove functions: string_del_append(), string_del_leading(),
string_del_trailing(), string_flatten(), string_get_before(),
string_get_leading(), string_replace_all(), string_sed_s(),
and their auxiliary functions.

the shell specified in the argument of `--shell'.
- If no shell was specified at run-time, `ash' is tried first;
if `ash' is not available continue with the shell with which
groffer was called from the command line, or with the shell
name in the first line of the script, actually `/bin/sh'.
2002-07-12 Bernd Warken
________________________________________________________________
* fixes for groffer 0.9.0
* groffer.sh: enhance version information
`groffer -v|--version' now print:
- groffer's version number and date

- groff's version information (version number and copyright),
but not groff's `called subprograms' information.
* groffer.sh: minor fixes
- Fix the argument parser to process argument `-' correctly.
- Some display programs have trouble with empty input; feed a
line consisting of a single space character in this case for
all display modes (not for source or groff modes).
* TODO:
fix entry `shoop' (not 'shopt').
2002-06-28 Bernd Warken
________________________________________________________________
* release of groffer 0.9.0
* groffer.sh: new mode `pdf'
- PDF (Portable Document Format):
-> Transform groff `ps' output into pdf using `gs'.
-> Pro: PDF viewers provide text searching (!).
-> Con: the transformation is quite slow.
-> Not suitable as an auto mode.
- New options `--pdf', `--pdf-viewer', `--mode pdf'.

________________________________________________________________
* release of groffer 0.8
* Makefile.sub: add copyright section
* groffer.man:
- Document the new options.
- Revise the documentation of the modes.
- Document the configuration files in new section `FILES'.
- Redesign section `EXAMPLES'.
- Remove documentation for `-W'.
* groffer.sh: new debugging features
- Disabled by default; enabled by environment variables.
- Add landmark() to catch typos with quotes.
- Add a function call stack for suitable functions; implemented
as within the argument checker func_check().
- This implies the need to provide `return' with some clean-up
facility; implemented as `eval "$_return_..."'.
- Add option `--debug' to enable debugging at run-time.
- Actually, the groffer script uses only shell builtins found
in `ash' (a subset of POSIX) and POSIX `sed' as the only
external shell utility.
* groffer.sh: customization of viewers
- In `groff' mode, the groffer viewing facilities are disabled.
- The postprocessor option `-P' costumizes the viewer only in
some situations in the `groff' mode, so a new infrastructure
for viewer customization is necessary.
- Allow to specify arguments to the viewer programs specified
in `--*-viewer()'.
- Implement some of the essential X Toolkit resource options in
groffer, but with use a leading double minus.
-> `--bd': set border color.

-> `--title': set viewer window title.
-> `--xrm': set X resource.
- Remove misnamed option `--xrdb'.
* groffer.sh: new mode structure
- New Postcript mode `ps' (`--ps'):
-> default viewers: gv,ghostview,gs_x11,gs;
-> `--ps-viewer' sets the Postscript viewer.
- New mode `www' (`--www') for displaying in a web browser:
-> default browsers: mozilla,netscape,opera,amaya,arena;
-> `--www-viewer' sets the web browser.
- New dvi mode (`--dvi'); default viewer `xdvi':
-> default viewers: xdvi,dvilx;
-> `--dvi-viewer' sets the dvi viewer.
- New mode `auto':
-> active if no other mode is given or by new option `--auto';
-> selects from a sequence of modes that are tested until one
of them succeeds.
-> the default mode sequence is actually `ps', `x', `tty'.
-> `--default-modes' sets this mode sequence as a comma
separated string of program names, optionally each one
with arguments).
- New mode `groff':
-> process input like groff, ignore viewing options.
-> activated by new option `--groff'.
-> automatically active with one of `-V', `-X', `-Z'.
- Revise `tty' mode:
-> allow several text devices.
->
- Reorganize the mode management:
-> new mode setting option `--mode'.
-> logically separate source, groff, and display modes.
-> intermediate output mode is now part of mode groff; remove
any special features around `-Z'.
- Update usage() to reflect the new option structure.
* groffer.sh: add configuration files
- `/etc/groff/groffer.conf' system-wide configuration.
- `${HOME}/.groff/groffer.conf' user configuration.
- The configuration file are shell scripts for now; later
implementations can identify this from the `#! /bin/sh' line.
* groffer.sh: new data structure `list':
- Implement a `list' data structure as a string consisting of
single-quoted elements, separated by a space character;
embedded single-quotes are escaped.
* groffer.sh: new option parser based on `list':
- Write new option parser based on `list', compatible to both
POSIX getopts() and GNU getopt().
- Long options are now available on GNU and non-GNU systems.
- Get rid of POSIX getopts() and GNU getopt().
- the `-W--longopt' construct is now obsolete; remove it.
- add test/function for `unset'.
- Option strings are now implemented as `list's in order to
allow unusual characters in options.
- Parse $MANOPT first; translate essential arguments into
groffer options.
* groffer.man:
- determine prompt length for `.Shell_cmd'* dynamically.
- naming scheme for static strings and registers changed to
`namespace:macro.variable'.
2002-06-16 Werner Lemberg <wl@gnu.org>
* groffer.sh:
Implement man option `--ascii' by `-mtty-char'.
2002-05-31 Werner LEMBERG <wl@gnu.org>
* groffer.man (@.Shell_cmd_width):
Increase to 4m (we use `sh#' as the prompt).
2002-05-31 Bernd Warken
________________________________________________________________
* release of groffer 0.7
* groffer.sh: remove incompatibilities with the `ash' shell:
- do not use `!command':
-> use `else'
-> write `_not_' equivalents for some functions
- do not use `[^]' in `case':
-> restructure some functions.
- only single-character names for loop variables:
-> spoils the paradigm of leading `_' for local variables.
- spurious trouble with `for i in ${var}':
-> use `eval set -- ${var}' and `for i in "$@"'
- do not change or use $IFS:
-> define new functions string_split() and `path_split()'.
-> result must be processed by `eval set --'.
-> solve conflicts with existing positional parameters.
- trouble with exporting external `$GROFF_*' variables:
-> hope that they were exported in the calling shell.
- not smart about additional blanks:
-> remove unnecessary white space.
* groffer.sh: improve run-time speed:
- `ash' more than doubles the speed of `bash'.
- speed-up `man_setup()'.
2002-05-30 Werner Lemberg <wl@gnu.org>
* groffer.man:
- remove some wrong `\:'.
- rename macro names that start with a `[' (clashes with refer).
- fix TP_header.
2002-05-28 Bernd Warken
________________________________________________________________

Due to the many changes, shorten and rearrange the entries
since groffer 0.5 .
________________________________________________________________
* Shell compatibility
* groffer.sh:
- Due to possible conflicts in old BSD versions, `[]' was
replaced by `test'; the `test' options `-a' and `-o' were
replaced by multiple calls of `test'.
- Write interface to the `sed' command `s' to become
independent of the delimiter character. Rewrite all text
manipulating function to use this new scheme. The new
functions are named `string_*'.
- `tr' is not needed any longer, replaced by `sed'.
- `grep' is not needed any longer, mostly replaced by `case'.
- Revision of test for `getopt'.
- Remove `set -a'; explicitly export variables.

and functions (OOP-like).
- Introduce variables for white space (better readability with
$IFS).
- Store the names of the processed filespecs into a variable
instead of a temporary file.
- Error-prone shell constructions were replaced by functions
with a simple interface.

`source', `default', `auto', etc.
- Make the handling of the X mode like in groff (e.g. -X -Tps).
- Make resolution for gxditview behave like groff (default
75 dpi).
- Add environment variable $GROFFER_OPT to preset groffer
options.
