"Description:\n"
|
|
" When <exefile> <offset> are given, log2lines works like raddr2line:\n"
|
|
" - The <exefile> <offset> combination can be repeated\n"
|
|
" - Also, <offset> can be repeated for each <exefile>\n"
|
|
" - NOTE: Some of the options below will have no effect in this form.\n"
|
|
" Otherwise it reads stdin and tries to translate lines of the form:\n"
|
|
" <IMAGENAME:ADDRESS>\n"
|
|
" The result is written to stdout.\n\n"
|
|
" <offset> or <ADDRESS> can be absolute or relative with the restrictions:\n"
|
|
" - An image with base < 0x400000 MUST be relocated to a > 0x400000 address.\n"
|
|
" - The offset of a relocated image MUST be relative.\n\n"
|
|
" log2lines uses a cache in order to avoid a directory scan at each\n"
|
|
" image lookup, greatly increasing performance. Only image path and its\n"
|
|
" base address are cached.\n\n"
|
|
"Options:\n"
|
|
" -b Use this combined with '-l'. Enable buffering on logFile.\n"
|
|
" This may solve loosing output on real hardware (ymmv).\n\n"
|
|
" -c Console mode. Outputs text per character instead of per line.\n"
|
|
" This is slightly slower but enables to see what you type.\n\n"
|
|
" -d <directory>|<ISO image>\n"
|
|
" <directory>: Directory to scan for images. (Do not append a '" PATH_STR "')\n"
|
|
" <ISO image>: This option also takes an ISO image as argument:\n"
|
|
" - The image is recognized by the '.iso' or '.7z' extension.\n"
|
|
" - NOTE: The '.7z' and extracted '.iso' basenames must be identical,\n"
|
|
" which is normally true for ReactOS trunk builds.\n"
|
|
" - The image will be unpacked to a directory with the same name.\n"
|
|
" - The embedded reactos.cab file will also be unpacked.\n"
|
|
" - Combined with -f the file will be re-unpacked.\n"
|
|
" - NOTE: this ISO unpack feature needs 7z to be in the PATH.\n"
|
|
" Default: " DEF_OPT_DIR "\n\n"
|
|
" -f Force creating new cache.\n\n"
|
|
" -F As -f but exits immediately after creating cache.\n\n"
|
|
" -h This text.\n\n"
|
|
" -l <logFile>\n"
|
|
" <logFile>: Append copy to specified logFile.\n"
|
|
" Default: no logFile\n\n"
|
|
" -L <logFile>\n"
|
|
" <logFile>: (Over)write copy to specified logFile.\n"
|
|
" Default: no logFile\n\n"
|
|
" -m Prefix (mark) each translated line with '* '.\n\n"
|
|
" -M Prefix (mark) each NOT translated line with '? '.\n"
|
|
" ( Only for lines of the form: <IMAGENAME:ADDRESS> )\n\n"
|
|
" -P <cmd line>\n"
|
|
" Pipeline command line. Spawn <cmd line> and pipeline its output to\n"
|
|
" log2lines (as stdin). This is for shells lacking support of (one of):\n"
|
|
" - Input file redirection.\n"
|
|
" - Pipelining byte streams, needed for the -c option.\n\n"
|
|
" -r Raw output without translation.\n\n"
|
|
" -s Statistics. A summary with the following info is printed after EOF:\n"
|
|
" *** LOG2LINES SUMMARY ***\n"
|
|
" - Translated: Translated lines.\n"
|
|
" - Reverted: Lines translated back. See -u option\n"
|
|
" - Retranslated: Lines retranslated. See -U option\n"
|
|
" - Skipped: Lines not translated.\n"
|
|
" - Differ: Lines where (addr-1) info differs. See -tT options\n"
|
|
" - Differ(func/src):Lines where also function or source info differ.\n"
|
|
" - Rev conflicts: Source files conflicting with build. See '-R check'\n"
|
|
" - Reg candidates: Regression candidates. See '-R regscan'\n"
|
|
" - Offset error: Image exists, but error retrieving offset info.\n"
|
|
" - Total: Total number of lines attempted to translate.\n"
|
|
" Also some version info is displayed.\n\n"
|
|
" -S <context>[+<add>][,<sources>]\n"
|
|
" Source line options:\n"
|
|
" <context>: Source lines. Display up to <context> lines until linenumber.\n"
|
|
" <add> : Optional. Display additional <add> lines after linenumber.\n"
|
|
" <sources>: Optional. Specify alternate source tree.\n"
|
|
" The environment variable " SOURCES_ENV " should be correctly set\n"
|
|
" or specify <sources>. Use double quotes if the path contains spaces.\n"
|
|
" For a reliable result, these sources should be up to date with\n"
|
|
" the tested revision (or try '-R check').\n"
|
|
" Can be combined with -tTR.\n"
|
|
" Implies -U (For retrieving source info) and -R check.\n\n"
|
|
" -t Translate twice. The address itself and for (address-1).\n"
|
|
" Show extra filename, func and linenumber between [..] if they differ\n"
|
|
" So if only the linenumbers differ, then only show the extra\n"
|
|
" linenumber.\n\n"
|
|
" -T As -t, but show only filename+func+linenumber for (address-1)\n\n"
|
|
" -u Undo translations.\n"
|
|
" Lines are translated back (reverted) to the form <IMAGENAME:ADDRESS>\n"
|
|
" Also removes all lines previously added by this tool (e.g. see -S)\n\n"
|
|
" -U Undo and reprocess.\n"
|
|
" Reverted to the form <IMAGENAME:ADDRESS>, and then retranslated\n"
|
|
" Implies -u.\n\n"
|
|
" -v Show detailed errors and tracing.\n"
|
|
" Repeating this option adds more verbosity.\n"
|
|
" Default: only (major) errors\n\n"
|
|
" -z <path to 7z>\n"
|
|
" <path to 7z>: Specify path to 7z. See also option -d.\n"
|
|
" Default: '7z'\n"
|
|
"\n"
|
|
"CLI escape commands:\n"
|
|
" It is possible to change options and perform actions from the 'kdb:>' prompt\n"
|
|
" By prepending the `(backquote) character to the option.\n"
|
|
" Example: 'kdb:> `l new.log' changes the current logfile to 'new.log'.\n"
|
|
" Flag options like 'b' are given a numeric value of 0 (off) or 1 (on).\n"
|
|
" Options accepting a string as argument can be cleared by the value '" KDBG_ESC_OFF "'.\n"
|
|
" Some ClI commands are read only or not (entirely) implemented.\n"
|
|
" If no value is provided, the current one is printed.\n"
|
|
" There are a few extra ClI commands or with different behaviour:\n"
|
|
" - `a <module>:<reladdress>:\n"
|
|
" - Outputs absolute address e.g. for setting breakpoints.\n"
|
|
" - Do a 'mod' first to retrieve relocation info.\n"
|
|
" - `h : shows this helptext (without exiting)\n"
|
|
" - `q : quits log2lines\n"
|
|
" - `s : the output is printed immediately\n"
|
|
" - `s clear : clears all statistics.\n"
|
|
" - `S : only <context> and <add> can be set.\n"
|
|
" - `v <level> : sets the current debug loglevel\n"

|
|
" Use kdbg debugger via console, and append copy to logFile:\n"
|

" log2lines -c -l dbg.log < \\\\.\\pipe\\kdbg\n\n"

" Same as above, but for PowerShell:\n"

" Use kdbg debugger to send output to logfile:\n"

" Re-translate a debug log:\n"
