-------------------------------------------------------------------- -.SS Further Study of Experimental Additions -.\" -------------------------------------------------------------------- -. -A number of suggestions have been made for extending the -.I control word -language of -.FONT CI RUNOFF R , -and its capabilities. -. -These are listed here, primarily to elicit comment and discussion, -both on the language which describes these operations and the less -important problem of their implementation. -- -. -.TP -1. -. -Word division. -. -This is a whole are of study in itself. -. -. -.TP -2. -. -Automatic footnote insertion. -. -This was handled somewhat awkwardly in the -.FONT CB .DITTO -.IR command , -although the basic approach was probably reasonable. -. -. -.TP -3. -. -Automatic page references, perhaps via some symbolic reference scheme. -. -This would enable the page number in "as was described on page 32" to -be inserted by the program. -. -The analogy with an assembly program should be hotly pursued for -ideas. -. -. -.TP -4. -. -Special provision for printing facing pages. -. -This would require alternate running heads, placing page numbers -alternately at right and left, and matching line counts on facing -pages. -. -. -.TP -5. -. -Improved page\-division rules, to prevent the last line of a paragraph -appearing alone at the top of a page, for example. -. -At present, copy must be run off to check by hand that awkward page -divisions have not been made. -. -. -.TP -6. -. -Automatic generation of page numbers for a table of contents. -. -Again, the analogy of an assembly program symbol table appears -fruitful. -. -. -.TP -7. -. -Automatic generations of an index. -. -The problem here is obtaining too many references to a given word, -many irrelevant. -. -. -.TP -8. -. -Arrangement of tabulated data. -. -This problem may have already been partly approached with the -above\-described figure generator, or the facilities already available -in -.IR RUNOFF , -but automatic setup of column widths and positions would be desirable. -. -One could include in this category the ability to call on other -programs to computer numbers to place in tables, although this is -going pretty far afield. -. -. -.TP -9. -. -Placing figures in a -.I "cut" -or -.IR inset . -. -The control language is the most difficult problem here. -. -. -.TP -10. -. -Equation typing

-------------------------------------------------------------------- -.SS Further Study of Experimental Additions -.\" -------------------------------------------------------------------- -. -A number of suggestions have been made for extending the -.I control word -language of -.FONT CI RUNOFF R , -and its capabilities. -. -These are listed here, primarily to elicit comment and discussion, -both on the language which describes these operations and the less -important problem of their implementation. -- -. -.TP -1. -. -Word division. -. -This is a whole are of study in itself. -. -. -.TP -2. -. -Automatic footnote insertion. -. -This was handled somewhat awkwardly in the -.FONT CB DITTO -.IR command , -although the basic approach was probably reasonable. -. -. -.TP -3. -. -Automatic page references, perhaps via some symbolic reference scheme. -. -This would enable the page number in "as was described on page 32" to -be inserted by the program. -. -The analogy with an assembly program should be hotly pursued for -ideas. -. -. -.TP -4. -. -Special provision for printing facing pages. -. -This would require alternate running heads, placing page numbers -alternately at right and left, and matching line counts on facing -pages. -. -. -.TP -5. -. -Improved page\-division rules, to prevent the last line of a paragraph -appearing alone at the top of a page, for example. -. -At present, copy must be run off to check by hand that awkward page -divisions have not been made. -. -. -.TP -6. -. -Automatic generation of page numbers for a table of contents. -. -Again, the analogy of an assembly program symbol table appears -fruitful. -. -. -.TP -7. -. -Automatic generations of an index. -. -The problem here is obtaining too many references to a given word, -many irrelevant. -. -. -.TP -8. -. -Arrangement of tabulated data. -. -This problem may have already been partly approached with the -above\-described figure generator, or the facilities already available -in -.IR RUNOFF , -but automatic setup of column widths and positions would be desirable. -. -One could include in this category the ability to call on other -programs to computer numbers to place in tables, although this is -going pretty far afield. -. -. -.TP -9. -. -Placing figures in a -.I "cut" -or -.IR inset . -. -The control language is the most difficult problem here. -. -. -.TP -10. -. -Equation typing and numbering. -. -Again, the control language appears formidable. -. -. -.\" -------------------------------------------------------------------- -.SH MANUSCRIPT CONVENTIONS -.\" -------------------------------------------------------------------- -. -Initially, -.FONT CI RUNOFF -is set to -.I FILL -mode, such as by using -.FONT CB .FILL R . -. -The filling is identical to -.FONT CI groff R 's -filling mode: -. -Text lines will normally be adjuted by inserting extra spaces in -mid\-line so that the end of the line is on the right margin. -. -. -.\"

-------------------------------------------------------------------- -. -The argument handling of options -. -. -.P -.FONT CI "Short options" -are arguments that start with a single dash -.FONT CB \- R . -. -Such an argument can consist of arbitrary many options without option -argument, composed as a collection of option characters following the -single dash. -. -. -.P -Such a collection can be terminated by an option character that -expects an option argument. -. -If this option character is not the last character of the argument, -the follwing final part of the argument is the option argument. -. -If it is the last character of the argument, the next argument is -taken as the option argument. -. -. -.P -This is the standard for -.FONT CI POSIX -and -.FONT CI GNU -option management. -. -. -.P -For example, -. -.TP -.FONT CB \-kVesome_dir -is a collection of the short options -.FONT CB \-k -and -.FONT CB \-V -without option argument, followed by the short option -.FONT CB \-e -with option argument that is the following part of the argument -.FONT CB some_dir R . -. -So this argument could also be written as several arguments -.FONT CB "\-k \-V \-e some_dir" R . -. -. -.\" -------------------------------------------------------------------- -.SS "Handling of Long Options" -.\" -------------------------------------------------------------------- -. -Arguments that start with a double dash -.FONT CB \-\- -are so-called -.FONT CI "long options" R . -. -Each double dash argument can only have a single long option. -. -. -.P -.FONT CI "Long options" -have or have not an option argument. -. -An option argument can be the next argument or can be appended with an -equal sign -.FONT CB = -to the same argument as the long option. -. -. -.TP -.FONT CB \-\-help -is a long option without an option argument. -. -.TP -.FONT CB "\-\-eps_dir some_dir" -.TQ -.FONT CB "\-\-eps_dir=some_dir" -is the long option -.FONT CB "\-\-eps_dir -with the option argument -.FONT CB some_dir R . -. -. -.P -Moreover the program allows abbreviations of long options, as much as -possible. -. -. -.P -The -.FONT CI "long option" -.FONT CB \-\-keep_all -can be abbreviated from -.FONT CB \-\-keep_al -up to -.FONT CB \-\-k -because the program does not have another -.FONT CI "long option" -whose name starts with the character -.FONT CB k R . -. -. -.P -On the other hand, the option -.FONT CB \-\-version -cannot be abbreviated further than -.FONT CB \-\-vers -because there is also the -.FONT CI "long option " CB \-\-verbose -that can be abbreviated up to -.FONT CB \-\-verb R . -. -. -.P -An option argument can also be appended to an abbreviation. -. -So is -.FONT CB \-\-e=some_dir -the same as -.FONT CB "\-\-eps_dir some_dir" R . -. -. -.P -Moreover the program allows an arbitrary usage of upper and lower case -in the option name. -. -This is -.FONT CI Perl -style. -. -. -.P -For example, the -.FONT CI "long option" -.FONT CB \-\-keep_all -can as well be written as

-Each input must be written in the -.FONT CI roff -or -.FONT CI groff -language and can include -.FONT CI lilypond -parts. -. -. -.P -Normally arguments starting with a dash -.FONT CB \- -are

It is loaded by - `perl/groffer.pl'. - - * perl/func.pl: This is the collection of miscellaneous functions. - It is loaded by `perl/groffer.pl'. - - * perl/split_env.sh: A shell script that is used by - `perl/groffer.pl' to split a large shell environment variable to a - Perl array. - - * perl/groffer.man: This is the man page of the Perl version of - `groffer'. It is derived from `groffer.man' of the shell version. - It will only be installed when the `Makefile.sub' chooses to - install the Perl version of 'groffer' instead of the shell - version. - - * perl/README_PERL: This file contains information of the Perl - compatibility and details that are special to the Perl version. - - * shell/: Subdirectory for the shell version of `groffer'. - - * shell/ChangeLog.0: The former `ChangeLog' file of the groffer - versions 0.* was moved to this file. It contains information of - the shell only version of groffer 0.*. - - * shell/groffer.sh: This is the old `groffer.sh' file of the shell - version. - - * shell/groffer2.sh: This is the old `groffer2.sh' file of the - shell version. - - * shell/groffer.man: This is the old man page groffer.man of the - shell version. The shell version keeps its own man page.

-------------------------------------------------------------------- -. -The -.B \%groffer -program is the easiest way to use -.BR \%groff (@MAN1EXT@). -It can display arbitrary documents written in the -.I \%groff -language, see -.BR \%groff (@MAN7EXT@), -or other -.I \%roff -languages, see -.BR \%roff (@MAN7EXT@), -that are compatible to the original -.I \%troff -language. -. -It finds and runs all necessary -.I groff -preprocessors, such as -.BR @g@chem . -. -. -.P -The -.B \%groffer -program also includes many of the features for finding and displaying -the \%\f[CR]Unix\f[] manual pages -.nh -.RI ( man\~pages ), -.hy -such that it can be used as a replacement for a -.BR \%man (1) -program. -. -Moreover, compressed files that can be handled by -.BR \%gzip (1) -or -.BR \%bzip2 (1) -are decompressed on-the-fly. -. -. -.P -The normal usage is quite simple by supplying a file name or name of a -.I \%man\~page -without further options. -. -But the option handling has many possibilities for creating special -behaviors. -. -This can be done either in configuration files, with the shell -environment variable -.Env_var \%$GROFFER_OPT , -or on the command line. -. -. -.P -The output can

\%$HOME/.groff/groffer.conf -User-specific configuration file for -.BR \%groffer , -where -.Env_var \%$HOME -denotes the user's home directory. -. -This file is called after the system-wide configuration file to enable -overriding by the user. -. -. -.P -Both files are handled for the configuration, but the configuration -file in -.File_name /etc -comes first; it is overwritten by the configuration file in the home -directory; both configuration files are overwritten by the environment -variable -.Env_var \%$GROFFER_OPT ; -everything is overwritten by the command line arguments. -. -. -.P -The configuration files contain options that should be called as -default for every -.B \%groffer -run. -. -These options are written in lines such that each contains either a -long option, a short option, or a short option cluster; each with or -without an argument. -. -So each line with configuration information starts with a minus -character -.RB ` \- '; -a line with a long option starts with two minus characters -.RB ` \-\- ', -a line with a short option or short option cluster starts with a -single minus -.RB ` \- '. -. -. -.P -The option names in the configuration files may not be abbreviated, -they must be exact. -. -. -.P -The argument for a long option can be separated from the option name -either by an equal sign -.RB ` = ' -or by whitespace, i.e. one or several space or tab characters. -. -An argument for a short option or short option cluster can be directly -appended to the option name or separated by whitespace. -. -The end of an argument is the end of the line. -. -It is not allowed to use a shell environment variable in an option -name or argument. -. -. -.P -It is not necessary to use quotes in an option or argument, except for -empty arguments. -. -An empty argument can be provided by appending a pair of quotes to the -separating equal sign or whitespace; with a short option, the -separator can be omitted as well. -. -For a long option with a separating equal sign -.RB ` = ', -the pair of quotes can be omitted, thus ending the line with the -separating equal sign. -. -All other quote characters are cancelled internally. -. -. -.P -In the configuration files, arbitrary whitespace is allowed at the -beginning of each line, it is just ignored. -. -Each whitespace within a line is replaced by a single space character -` ' internally. -. -. -.P -All lines of the configuration lines that do not start -with a minus character are ignored, such that comments starting with -.RB ` # ' -are possible. -. -So there are no shell commands in the configuration files. -. -. -.P -As an example, consider the following configuration file that can be -used either in -.File_name \%/etc/groff/groffer.conf -or -.File_name \%~/.groff/groffer.conf . -.

-------------------------------------------------------------------- -. -The -.B \%groffer -program is written in Perl, the Perl version during writing was v5.8.8. -. -. -.P -.B \%groffer -provides its own parser for command line arguments that is compatible -to both \%\f[CR]POSIX\fP -.BR \%getopts (1) -and \%\f[CR]GNU\fP -.BR \%getopt (1). -It can handle option arguments and file names containing white space -and a large set of special characters. -. -The following standard types of options are supported. -. -. -.Topic -The option consisting of a single minus -.B - -refers to standard input. -. -. -.Topic -A single minus followed by characters refers to a single character -option or a combination thereof; for example, the -.B \%groffer -short option combination -.B -Qmfoo -is equivalent to -.BR -Q\~\-m\~foo . -. -. -.Topic -Long options are options with names longer than one character; they -are always preceded by a double minus. -. -An option argument can either go to the next command line argument or -be appended with an equal sign to the argument; for example, -.B --long=arg -is equivalent to -.BR --long\~arg . -. -. -.Topic -An argument of -.B -- -ends option parsing; all further command line arguments are -interpreted as -.I \%filespec -parameters, i.e. file names or constructs for searching -.IR \%man\~pages ). -. -. -.Topic -All command line arguments that are neither options nor option -arguments are interpreted as -.I \%filespec -parameters and stored until option parsing has finished. -. -For example, the command line -.sp -.EX -\fIsh#\fR\~groffer file1 -a -o arg file2 -.EE -.sp -is equivalent to -.sp -.EX -\fIsh#\fR\~groffer -a -o arg -- file1 file2 -.EE -.sp -. -.P -The free mixing of options and -.I \%filespec -parameters follows the GNU principle. -. -That does not fulfill the strange option behavior of \%\f[CR]POSIX\fP -that ends option processing as soon as the first non-option argument -has been reached. -. -The end of option processing can be forced by the option -.RB ` \-\- ' -anyway. -. -. -.\" -------------------------------------------------------------------- -.SH "BUGS" -.\"

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@'. - -2005-06-23 Bernd Warken <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * release of groffer 0.9.17 - - * groffer.sh: get rid of `local' in functions (it is not POSIX) - - Replace local variables by variable names with a special prefix - 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. - - Several variables were forgotten to make local.

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. - -2004-05-29 Bernd Warken <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * release of groffer 0.9.9 - - * groffer.sh: - Fix first run section to allow the starting shell to go on if - `ash' is not available. - - * groffer.man: - Remove unnecessary information on groffer version. - -2004-05-12 Bernd Warken <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * release of groffer 0.9.8 - - * groffer.sh: - Fix problems of `test' by adding subs to arguments. - - * groffer.man: - Write the file license as macros that are called in sections - AUTHOR and COPYING. - - * .cvsignore: - Restore this file. - -2004-04-30 Bernd Warken <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * release of groffer 0.9.7 - - * groffer.sh: - - obj(), obj_data(), obj_from_output(), obj_set(): New object - oriented functions to minimize complicated `eval' commands. - - list_*(): Corrections. - - usage(): Streamlining. - - * groffer.man, README_SH: - Corrections. - -2004-04-27 Bernd Warken <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * release of groffer 0.9.6 - - This version replaces the license of all files except ChangeLog of - the groffer source to the GNU General Public License (GPL) of the - version described in files COPYING and LICENSE in the groff top - source directory. - - * groffer.man: - Changement from the GNU Free Documentation License (FDL) to - the GNU General Public License (GPL). - - * README, README_SH, TODO: - Add license GNU General Public License (GPL). - - * Makefile.sub, groffer.sh: - Keep the GNU General Public License (GPL), but refer to the - COPYING and LICENSE files. - - * ChangeLog: Add a license in the style of Emacs ChangeLog file, - which is weaker than the GPL, but has its flavor. - -2004-04-24 Bernd Warken <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * 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 <groff-bernd.warken-72@web.de> - ________________________________________________________________ - * release of groffer 0.9.4 - - * groffer.sh: corrections for some restrictive shells - - Possible exit codes in actual `ash' are between 0 and 63.

The `>' sign can be followed by another character that -shows how many of these arguments are possible. - -<arg> exactly 1 of this argument -<arg>? 0 or 1 of these arguments -<arg>* arbitrarily many such arguments, incl. none -<arg>+ one or more such arguments -<arg>... one or more such arguments -[...] optional arguments - -A function that starts with an underscore `_' is an internal function -for some other function. The internal functions are defined just -after their corresponding function. - - -External Environment Variables - -The groffer.sh script uses the following external system variables. -It is supposed that these variables are already exported outside of -groffer.sh; otherwise they do not have a value within the script. - -external system environment variables that are explicitly used -$DISPLAY: Presets the X display. -$LANG: For language specific man pages. -$LC_ALL: For language specific man pages. -$LC_MESSAGES: For language specific man pages. -$PAGER: Paging program for tty mode. -$PATH: Path for the programs called (`:' separated list). - -groffer native environment variables -$GROFFER_OPT preset options for groffer. - -all groff environment variables are used, see groff(1) -$GROFF_BIN_PATH: Path for all groff programs. -$GROFF_COMMAND_PREFIX: '' (normally) or 'g' (several troffs). -$GROFF_FONT_PATH: Path to non-default groff fonts. -$GROFF_TMAC_PATH: Path to non-default groff macro files. -$GROFF_TMPDIR: Directory for groff temporary files. -$GROFF_TYPESETTER: Preset default device. - -all GNU man environment variables are used, see man(1). -$MANOPT: Preset options for man pages. -$MANPATH: Search path for man pages (: list). -$MANROFFSEQ: Ignored because of grog guessing. -$MANSECT: Search man pages only in sections (:). -$SYSTEM: Man pages for different OS's (, list). - - -Object-oriented Functions - -The groffer script provides an object-oriented construction (OOP). In -object-oriented terminology, a type of object is called a `class'; a -function that handles objects from a class is named `method'. - -In the groffer script, the object is a variable name whose content is -the object's data. Methods are functions that have an object as first -argument. - -The basic functions for object handling are obj_*(). - -The class `list' represents an array structure, see list_*(). - - -Speed - -The major speed gain is the disabling of all debug features. This is -the default for the installed version of `groffer'. Before the run of -`make', the debug feature of $_DEBUG_FUNC_CHECK, corresponding to -option --debug-func, is enabled by default. The resulting heavy -slowing down should be regarded as a temporary feature. - -Another increase of speed was the replacement of the many `ls' calls -by analysing a `find' of manpath with `grep'. - - -Shell Compatibility - -The `groffer' shell scripts are compatible to both the GNU and the -POSIX shell and utilities. Care was taken to restrict the programming -technics used here in order to achieve POSIX compatibility as far back -as POSIX P1003.2 Draft 11.2 of September 1991. This draft is -available at http://www.funet.fi/pub/doc/posix/p1003.2/d11.2 on the -Internet. - -The POSIX draft does not include `local' variables for functions. So -this concept was replaced by global variables with a prefix that -differs for each function. The prefix is chosen from the function -name. These quasi-local variables are unset before each return of the -function. - -For shell compatibility, see also Autobook, chapter 22. - -The `groffer' scripts were tested under the shells `ash', `bash', -`bash-minimal', `dash', 'ksh', `mksh', `pdksh', 'posh', and `zsh' -without problems in Linux Debian. A shell can be tested by the -`groffer' option `--shell', but that will run only with groffer2.sh. -To start it directly from the beginning under this shell the following -command can be used. - - <shell-name> groffer.sh --shell=<shell-name> <argument>... - - -Some shells are not fully POSIX compatible. For them the following -restrictions were done. For more information look at the -documentation `Portable shells' in the `info' page of `autoconf' -(look-up in Emacs-Help-Manuals_Info). - -- The command parts `then', `else', and `do' must be written each on a - line of their own. - -- Replace `for i in "$@"' by `for i' and remove internal `;' (kah). - -- Replace `set -- ...' by `set x ...; shift'. After the first - non-option argument, all arguments including those starting with `-' - are accepted as non-option. For variables or `$()' constructs with - line-breaks, use `eval set' without quotes. That transforms a - line-break within a variable to a space. - -- The name of the variable in `for' is chosen as a single character - (old ash). The content of such variables is not safe because it can - also occur in other functions. So it is often stored in an - additional quasi-local variable. - -- `echo' is not portable on options; some `echo' commands have many - options, others have none. So `echo -n' cannot be used, such that - the output of each function has complete lines. There are two - methods to avoid having `-' as the first character of any argument. - Either a character such as `x' can be prepended to the argument; - this must later on be removed by `sed'. Otherwise, `echo' can be - replaced by `cat <<EOF'. - -- `ls' has problems. 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. - -- As `test -e' is not available in Solaris 2.5 replace it by - `test -f || test -d'. - -- As `unset' is not supported by all shells replace it by `eval - ${_UNSET}' where this variable is `unset' if it exists and `:' - otherwise. - -- Some shells have problems with options in `eval'. So quoting must - be done right to hide the options from `eval'. - -- In backquote calls `` avoid the backquote ` in comments. - -- Replace `true' by `:', `false' isn't used. - -- Do not redefine builtins as functions (ash). - -- Avoid `[^...]' in `case' patterns (ash). - -- `trap' does not allow error code 127. - -The scripts call the following commands with all options used: -. -: -apropos -break -bzip2 -c -d -t -cat -catz -cd -continue -echo -eval -expr -grep -groff -v -grog -T -X -Z -gs -c -d -f -q -s -gzip -c -d -f -less -r -R -ls -man -k --apropos -mkdir -mv -pwd -return -rm -f -r -rmdir -sed -e -n -set -e -sh -c -shift -test -c -d -f -r -s -w -x -trap -umask -unset - - -Bugs - -If the `groffer' run is interrupted by Crtl-C the clean up is not done -by all shells. The `trap' commands work for the shells `bash', -`bash-minimal', and 'ksh'; they do not work for `ash', `dash', -`pdksh', `posh', and `zsh'. - - -####### License - -Last update: 7 Feb 2011 - -Copyright (C) 2003-2006, 2009, 2011 - Free Software Foundation, Inc. -Written by Bernd Warken <groff-bernd.warken-72@web.de> - -This file is part of `groffer', which is part of `groff'. - -`groff' is free software; you can redistribute it and/or modify it -under the terms of the GNU General Public License as published by -the Free Software Foundation, either version 3 of the License, or -(at your option) any later version. - -`groff' is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY -or FITNESS FOR A PARTICULAR PURPOSE.

That -# starts with the so-called man path. This is determined in function -# man_setup() either by the command-line option --manpath, by $MANOPT, -# or by $MANPATH. There is also a program `manpath'. If all of this -# does not work a man path is created from $PATH with function -# manpath_set_from_path(). We now have a set of existing directories -# for the search of man pages; usually they end with `/man'. - -# The directory set of the man path can be changed in 2 ways. If -# operating system names are given in $SYSTEM or by --systems on the -# command-line all man path directory will be appended by these names. -# The appended system names replace the original man path; but if no -# system name is set, the original man path is kept. In `groffer', -# this is done by the function manpath_add_lang_sys() in man_setup(). - -# The next addition for directories is the language. It is specified -# by --locale or by one of the environment variables $LC_ALL, -# $LC_MESSAGES, and $LANG. The language name of `C' or `POSIX' means -# the return to the default language (usually English); this deletes -# former language specifications. The language name and its -# abbreviation with 2 characters is appended to the man page -# directories. But these new arising directories are added to the man -# page, they do not replace it such as the system names did. This is -# done by function manpath_add_lang_sys() in man_setup() as well. - -# Now we have the basic set of directories for the search of man pages -# for given filespec arguments. The real directories with the man -# page source files are gotten by appending `man<section>' to each -# directory, where section is a single character of the form -# `[1-9on]'. - -# There you find files named according to the form -# <name>.<section>[<extension>][<compression>], where `[]' means -# optional this time. <name> is the name of the man page; <section> -# is the single character from the last paragraphe; the optional -# <extension> consists of some letters denoting special aspects for -# the section; and the optional <compression> is something like `.gz', -# `.Z', or `.bz2', meaning that the file is compressed. - -# If name, section. and extension are specified on the command-line -# the file of the form <name>.<section><extension> with or without -# <compression> are handled. The first one found according to the -# directory set for the section is shown. - -# If just name and section are specified on the command-line then -# first <name>.<section> with or without <compression> are searched. -# If no matching file was found, <name>.<section><extension> with or -# without <compression> are searched for all possible extensions. - -# If only name is specified on the command-line then the section -# directories are searched by and by, starting with section `1', until -# a file is matched. - -# The function man_is_man() determines all suitable man files for a -# command-line argument, while man_get() searches the single matching -# file for display. - - -######################################################################## -# man_get (<man-name> [<section> [<extension>]]) -# -# Write a man page to the temporary file. -# -# Globals in: $_TMP_MANSPEC, $_MAN_SEC_CHARS, $_MAN_EXT, $_MAN_ALL -# -# Arguments: 1, 2, or 3 -# -# Variable prefix: mg -# -man_get() -{ - func_check man_get '>=' 1 "$@";
