FMTTEST(1) General Commands Manual FMTTEST(1) NAME fmttest - test programs in nmh's mh-format(5) language SYNOPSIS fmttest [-help] [-version] [-form formatfile] [-format formatstring] [-ad- dress | -raw | -date | -message] [-file | -nofile] [--component compo- nent-text] [-dupaddrs | -nodupaddrs] [-ccme | -noccme] [-outsize size- in-characters] [-width column-width] [-msgnum number] [-msgcur flag] [-msgsize size] [-unseen flag] [-dump | -nodump] [-trace | -notrace] [+folder] [msgs | strings] DESCRIPTION fmttest is used to test programs written for the nmh format language as specified by mh-format(5). It is also intended to replace the ap, dp, and fmtdump programs. Format Program Selection The -format string and -form formatfile specify a format string or file to read. A format string, if given, must be a single argument to the -format switch. If a format file name is passed to the -form, switch, the file is searched for using the normal nmh rules: absolute pathnames are accessed directly, tilde expansion is done on usernames, and files are searched for in the user's Mail directory as specified in their profile. If not found there, the directory "/usr/local/etc/nmh" is checked. Mode Selection and Component Specification fmttest has four operating modes - address, raw, date, and message - which are selected by the -address, -raw, -date, and -message switches, respec- tively. Address mode treats every argument as an email address to be processed by nmh's email parser using the specified format program. The parsed address is made available as a special %{text} component escape, and the output from the program is printed on standard output. If there was an error parsing the email address the error message is stored in the %{error} com- ponent escape. If no format program is given on the command line, the fol- lowing default program is used: %<{error}%{error}: %{text}%|%(putstr(proper{text}))%> Address mode is equivalent to ap(8). In raw mode, no processing of the specified arguments is done. Each argu- ment is run against the specified format program with the argument text available in the %{text} component. You must specify a format with -form or -format when using raw mode. Date mode is identical to raw mode, with one exception: if no format is specified, the following format string is used: %<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%> Date mode is equivalent to dp(8). In message mode the arguments to fmttest are interpreted as an optional folder and messages. fmttest will read each specified message and make all of the components in the message available to the format program. Also, the appropriate information for the %(msg), %(cur), %(unseen), and %(size) function escapes will be made available for each message. If the -file switch is given, the arguments are interpreted as filenames instead of mes- sage numbers, but otherwise the behavior is the same (except that the %(msg), %(cur), and %(unseen) function escapes will not provide any useful information). The default format used in address mode is the default format used by scan. The following command can replicate the functionality of the repl command. fmttest -nodupaddrs -form replcomps -outsize max [+folder] message Regardless of the mode, other components can be provided to the format pro- gram by the use of the --component switch. For example, the following pro- gram will test the use of the "encrypted" component: fmttest --encrypted yes -message cur In message mode, components supplied on the command line will override com- ponents from messages. Additional Switches The -dupaddrs and -nodupaddrs switches control whether duplicate addresses are allowed or suppressed by the FORMATADDR instruction, which is used by the `%(formataddr)' function escape. In normal operation duplicate ad- dresses are only suppressed by repl. The -ccme and -noccme switches control whether or not to count the user's local mailbox as a duplicate address. This replicates the behavior of the -cc me switch to repl, and only applies if -nodupaddrs is in effect. The -outsize switch controls the maximum number of printable characters that the format engine will produce. Characters marked as non-printing by the format engine with `%(zputlit)', characters with zero width, and extra bytes that are part of a multibyte character are not counted against this total. Two special values are supported: "max", which means as many char- acters as the format engine can produce (limited by internal buffers), and "width", which will set the value to the width of the terminal. In message mode it defaults to "width", otherwise the default is "max". The -width switch controls the column width which is used by the `%(width)' function escape. It defaults to the terminal width. The -msgnum, -msgcur, -msgsize, and the -unseen switches all control the values used, respectively, by the following function escapes: `%(num)', `%(cur)', `%(size)', and `%(unseen)'. If none are supplied, these values are taken from the message in message mode; in all other modes the default values are 0. Compiling and Tracing Format Programs The -dump switch outputs the complete set of format instructions for the specified format program. The -trace switch will output each format in- struction as it is being executed, and show the values of the num and str registers if they have changed from the previous instruction. The output buffer is also printed if it has changed from the previous instruction. Format Instructions It should be noted that there is not a one-to-one correspondence between format escapes and format instructions; many instructions have side ef- fects. Instructions prefixed with "LV" generally return a integer into the num (value) register; instructions prefixed with a "LS" return a string into the str register. Instruction Description COMP Output component COMPF Formatted output component LIT Output literal text CHAR Output single character NUM Output the num register NUMF Formatted output of the num register STR Output the str register STRF Formatted output of the str register STRFW Not used PUTADDR Output address list in str register STRLIT Output str, no space compression STRLITZ Like STRLIT, but not counted against width LS_COMP Write component to str register LS_LIT Write literal to str register LS_GETENV Write environment var to str register LS_DECODECOMP Decode RFC 2047 encoded component to str register LS_DECODE Decode RFC 2047 encoded string to str register LS_TRIM Trim trailing whitespace from str register LV_COMP Convert component to integer, store in num register LV_COMPFLAG Set num to 1 if TRUE set in component LV_LIT Load literal value into num register LV_DAT Load value from dat array into num register (see note) LV_STRLEN Set num to the length of str LV_PLUS_L Add value to num register LV_MINUS_L Subtract value from num register LV_DIVIDE_L Divide num register by value LV_MODULO_L num modulo value LV_CHAR_LEFT Store remaining number of printable chars in num LS_MONTH Write short name of month to str from date component LS_LMONTH Write long name of month to str from date component LS_ZONE Write time zone offset to str from date component LS_DAY Write short name of day of week to str from date component LS_WEEKDAY Write long name of day of week to str from date component LS_822DATE Write RFC 822 compatible date to str from date component LS_PRETTY Write date with "pretty" timezone to str LV_SEC Write date component seconds to num LV_MIN Write date component minutes to num LV_HOUR Write date component hour to num LV_MON Write date component numeric month to num (start at 1) LV_YEAR Write date component year to num LV_YDAY Write date component Julian day to num LV_WDAY Write date component day of week to num (0 == Sunday) LV_ZONE Write date component time zone offset to num LV_CLOCK Write date component in Unix epoch time to num LV_RCLOCK Write offset of date component from current time to num LV_DAYF Write 1 to num if day of week is explicit LV_DST Write 1 to num if DST is in effect for date component LV_ZONEF Write 1 to num if timezone is explicit LS_ADDR Write email address of addr component to str LS_PERS Write personal name of addr component to str LS_MBOX Write mailbox (username) of addr component to str LS_HOST Write host of addr component to str LS_PATH Write host route of addr component to str LS_GNAME Write group name of addr component to str LS_NOTE Write note portion of addr component to str LS_822ADDR Write "proper" RFC 822 version of addr component to str LS_FRIENDLY Write friendly (name or note) of address component to str LS_UNQUOTE Remove RFC 2822 quotes from string LV_HOSTTYPE Set num to type of host (0=local, 1=network) LV_INGRPF Set num to 1 if address was inside of group LV_NOHOSTF Set num to 1 of no host was present in address component LOCALDATE Convert date component to local timezone GMTDATE Convert date component to GMT PARSEDATE Parse date component PARSEADDR Parse address component FORMATADDR Add address component to list in str CONCATADDR Like FORMATADDR, but will not suppress duplicates MYMBOX Set num if address component is a local address SAVESTR Save str register temporarily DONE End program NOP No operation GOTO Jump to new instruction IF_S_NULL Branch if str is NULL IF_S Branch if str is not NULL IF_V_EQ Branch if num is equal to value IF_V_NE Branch if num is not equal to value IF_V_GT Branch if num is greater than value IF_MATCH Branch if str contains string IF_AMATCH Branch if str starts with string S_NULL Set num to 1 if str is NULL S_NONNULL Set num to 1 if str is not NULL V_EQ Set num to 1 if num equals value V_NE Set num to 1 if num does not equal value V_GT Set num to 1 if num is greater than value V_MATCH Set num to 1 if str contains string V_AMATCH Set num to 1 if str starts with string The LV_DAT instruction is a bit special. Callers of the format library pass in an array of integers that are used by certain format escapes. The current list of format escapes and the indexes they use are: dat[0] %(num) dat[1] %(cur) dat[2] %(size) dat[3] %(width) dat[4] %(unseen) SEE ALSO mh-format(5), repl(1), ap(8), dp(8), fmtdump(8) DEFAULTS `-message' `-nofile' `-dupaddrs' CONTEXT If a folder is given, it will become the current folder.
