Submit to CTAN. ## 30 Apr 2021 John Collins Revert the change of 14-15 Apr, by removing the ## of cwd(). That gave sometimes obnoxiously slow ## parsing of big log files, because of the slowness ## of large number of calls to cwd() caused by calls ## to sub normalize_filename. I think I am mistaken ## that cwd() could possibly give a different result ## than getcwd(), whose cached result is used by ## my goodcwd(). That idea was my motivation on 14 Apr. ## 22 Apr 2021 John Collins Clean up aux and out_dir code. ## 21 Apr 2021 John Collins Clean up some comments ## Add in emulation of -aux-directory. On by ## default. ## 20 Apr 2021 John Collins Add -dALLOWPSTRANSPARENCY option to ps2pdf and ## dvi2pdf. That avoids problems with recent ## ghostscript versions when, e.g., pstricks is used. ## 16 Apr 2021 John Collins Better normalization of aux_dir and out_dir, so ## that TEXMFOUTPUT, and the source and dest names for bibtex ## and makeindex allow them to work always when the aux_dir ## is **not** below cwd, at least under TeX Live. With MiKTeX ## bibtex works even without special precautions for aux_dir ## not below cwd. But makeindex doesn't work in this case, ## even if TEXMFOUTPUT is set correctly. ## 14-15 Apr 2021 John Collins In normalize_filename, try both good_cwd() and ## cwd() for removing directory component. ## That improves clean up. At least it could. ## V. 4.73. ## ## ## 1998-2021, John Collins: Many improvements and fixes. ## See CHANGE-log.txt for full list, and CHANGES for summaries ## ## Modified by Evan McLean (no longer available for support) ## Original script (RCS version 2.3) called "go" written by David J.

External executables can be native NT (which only know # NT-style file names) or cygwin executables (which normally # know both cygwin UNIX-style file names and NT file names, # but not always; some do not know about drive names, for # example). # Cygwin executables for tex and latex may only know cygwin # filenames. # 4. The BIBINPUTS environment variables may be # UNIX-style or MSWin-style depending on whether native NT or # cygwin executables are used. They are therefore parsed # differently. Here is the clash: # a. If a user is running under an NT shell, is using a # native NT installation of tex (e.g., fptex or miktex), # but has the cygwin executables in the path, then perl # detects the OS as cygwin, but the user needs NT # behavior from latexmk. # b. If a user is running under an UNIX shell in a cygwin # environment, and is using the cygwin installation of # tex, then perl detects the OS as cygwin, and the user # needs UNIX behavior from latexmk. # Latexmk has no way of detecting the difference. The two # situations may even arise for the same user on the same # computer simply by changing the order of directories in the # path environment variable ## Configuration parameters: We'll assume native NT executables. ## The user should override if they are not. # This may fail: perl converts MSWin temp directory name to cygwin # format.

UPDATE THE FOLLOWING!! # # We will need to determine whether source files for runs of various # programs are out of date. In a normal situation, this is done by # asking whether the times of the source files are later than the # destination files. But this won't work for us, since a common # situation is that a file is written on one run of latex, for # example, and read back in on the next run (e.g., an .aux file). # Some situations of this kind are standard in latex generally; others # occur with particular macro packages or with particular # postprocessors. # # The correct criterion for whether a source is out-of-date is # therefore NOT that its modification time is later than the # destination file, but whether the contents of the source file have # changed since the last successful run. This also handles the case # that the user undoes some changes to a source file by replacing the # source file by reverting to an earlier version, which may well have # an older time stamp. Since a direct comparison of old and new files # would involve storage and access of a large number of backup files, # we instead use the md5 signature of the files. (Previous versions # of latexmk used the backup file method, but restricted to the case # of .aux and .idx files, sufficient for most, but not all, # situations.) # # We will have a database of (time, size, md5) for the relevant # files. If the time and size of a file haven't changed, then the file # is assumed not to have changed; this saves us from having to # determine its md5 signature, which would involve reading the whole # file, which is naturally time-consuming, especially if network file # access to a server is needed, and many files are involved, when most # of them don't change. It is of course possible to change a file # without changing its size, but then to adjust its timestamp # to what it was previously; this requires a certain amount of # perversity. We can safely assume that if the user edits a file or # changes its contents, then the file's timestamp changes. The # interesting case is that the timestamp does change, because the file # has actually been written to, but that the contents do not change; # it is for this that we use the md5 signature. However, since # computing the md5 signature involves reading the whole file, which # may be large, we should avoid computing it more than necessary. # # So we get the following structure: # # 1. For each relevant run (latex, pdflatex, each instance of a # custom dependency) we have a database of the state of the # source files that were last used by the run. # 2. On an initial startup, the database for a primary tex file # is read that was created by a previous run of latex or # pdflatex, if this exists. # 3. If the file doesn't exist, then the criterion for # out-of-dateness for an initial run is that it goes by file # timestamps, as in previous versions of latexmk, with due # (dis)regard to those files that are known to be generated by # latex and re-read on the next run. # 4. Immediately before a run, the database is updated to # represent the current conditions of the run's source files. # 5. After the run, it is determined whether any of the source # files have changed. This covers both files written by the # run, which are therefore in a dependency loop, and files that # the user may have updated during the run. (The last often # happens when latex takes a long time, for a big document, # and the user makes edits before latex has finished. This is # particularly prevalent when latexmk is used with # preview-continuous mode.) # 6. In the case of latex or pdflatex, the custom dependencies # must also be checked and redone if out-of-date. # 7. If any source files have changed, the run is redone, # starting at step 1. # 8. There is naturally a limit on the number of reruns, to avoid # infinite loops from bugs and from pathological or unforeseen # conditions. # 9. After the run is done, the run's file database is updated. # (By hypothesis, the sizes and md5s are correct, if the run # is successful.) # 10. To allow reuse of data from previous runs, the file database # is written to a file after every complete set of passes # through latex or pdflatex. (Note that there is separate # information for latex and pdflatex; the necessary # information won't coincide: Out-of-dateness for the files # for each program concerns the properties of the files when # the other program was run, and the set of source files could # be different, e.g., for graphics files.) # # We therefore maintain the following data structures.: # # a. For each run (latex, pdflatex, each custom dependency) a # database is maintained. This is a hash from filenames to a # reference to an array: [time, size, md5]. The semantics of # the database is that it represents the state of the source # files used in the run. During a run it represents the state # immediately before the run; after a run, with all reruns, it # represents the state of the files used, modified by having # the latest timestamps for generated files. # b. There is a global database for all files, which represents # the current state. This saves having to recompute the md5 # signatures of a changed file used in more than one run # (e.g., latex and pdflatex). # c. Each of latex and pdflatex has a list of the relevant custom # dependencies. # # In all the following a fdb-hash is a hash of the form: # filename -> [time, size, md5] # If a file is found to disappear, its entry is removed from the hash. # In returns from fdb access routines, a size entry of -1 indicates a # non-existent file. # List of known rules.

It will have been read during # the run, so that even though the file changes during # a primary run, there is no need to trigger another # run because of this. # Size and md5 correspond to the values at the last run. # But time may be updated to correspond to the time # for the file, if the file is otherwise unchanged. # This saves excessive md5 calculations, which would # otherwise be done everytime the file is checked, # in the following situation: # When the file has been rewritten after a run # has started (commonly aux, bbl files etc), # but the actual file contents haven't # changed. Then because the filetime has # changed, on every file-change check latexmk # would normally redo the md5 calculation to # test for actual changes. Once one such # check is done, and the contents are # unchanged, later checks are superfluous, and # can be avoided by changing the file's time # in the source-file list. # 2: {Hash generated_file -> 1 } # This lists all generated files; the values # are currently unused, only the keys # 3: {Hash source_rule -> last_pass } # This lists rules that are to be considered source # rules for the current rule, separately from the # from_rules of the source files. It maps the name # of each of these rules to the pass number of the # current rule when it was last run. The current rule # is out-of-date if the last_pass for a source rule # is less than the pass number for the rule. # The purpose of this is when the source file list # is expected to be inaccurate, because the source # files are hard to determine. Typical needs are # for rules applied to dvi and xdv files, when # graphics files are involved. Their names are coded # inside the dvi/xdv file, but not the contents. # It would need parsing of the contents of the file # to determine the actual source files. # An implication of using a source_rule is that this # rule passes files to the current rule and that the # current rule can be considered out-of-date whenever # the source_rule has been run.
