For a full list of the templates, see get_filenames_templates_dict() If multiple inputs/outputs are given in the @values dictionary, we substitute @INPUT@ and @OUTPUT@ only if they are the entire string, not just a part of it, and in that case we substitute *all* of them. The typing of this function is difficult, as only @OUTPUT@ and @INPUT@ can be lists, everything else is a string. However, TypeDict cannot represent this, as you can have optional keys, but not extra keys. We end up just having to us asserts to convince type checkers that this is okay. https://github.com/python/mypy/issues/4617 rrrrc||d}t|ts Jd|S)Nrfor mypy)rrr)rrr6s rrz"substitute_values..replace#s: 1771:: !S!!--:---rc>g|]}|dvtj|S))r<r=)r escape)rrs rrz%substitute_values..-s+VVV#3>U3U3Ury~~3U3U3Ur|Nr<r rzFCommand has '@INPUT@' as part of a string and more than one input filer=zHCommand has '@OUTPUT@' as part of a string and more than one output filerD)rrrr) rAr rr#rrr_rrrr) r5r6routcmdrx_keysvalue_rxvvmoreinputsoutputsrs ` rrrrrs $ $GV444FVVVVVG07Arz#((7++,,,TH$ $  $"c""  MM"     "__I&FY& V!! bjjF1I>>????$&KLLL 2  Z(GZ'!W"" bjjWQZ@@AAAA$&LMMM 6\\r Aa%% 1 1z 1 1 1DD  <<,,DDD   MM$    MrrMrNci}|r||d<t|D]\}}||d|d<t|dkrRtj|dx|d<}tj|d|d<|r\||d<t|D]\}}||d |d<tj|d|d <|d d krd |d <|S) a  Create a dictionary with template strings as keys and values as values for the following templates: @INPUT@ - the full path to one or more input files, from @inputs @OUTPUT@ - the full path to one or more output files, from @outputs @OUTDIR@ - the full path to the directory containing the output files If there is only one input file, the following keys are also created: @PLAINNAME@ - the filename of the input file @BASENAME@ - the filename of the input file with the extension removed If there is more than one input file, the following keys are also created: @INPUT0@, @INPUT1@, ... one for each input file If there is more than one output file, the following keys are also created: @OUTPUT0@, @OUTPUT1@, ... one for each output file r<z@INPUTrr rr9r:r=z@OUTPUTr;rr) enumeraterrrbasenamer:dirname)rMrNr6r4rKplains rrJrJXs,F >"y!&)) ( (HR%'F>B>>> " " v;;!  ,.G,<,MNNN ? ? ?F   Ie    FF     FFF    JqMMMMM Ies/B B4B43B4c0eZdZdZd fd Zd fd ZxZS) r/zX Like TemporaryDirectory, but cleans things up using windows_proof_rmtree() excrrtbrrc t|||dS#t$rt|jYdSwxYwr)r__exit__rr|r)rrlrrmrs rroz#TemporaryDirectoryWinProof.__exit__s^ , GG  S% , , , , , , , ,  + + + + + + ,s#(A  A c tdS#t$rt|jYdSwxYwr)rcleanuprr|r)rrs rrqz"TemporaryDirectoryWinProof.cleanupsV , GGOO      , , ,  + + + + + + ,s %AA)rlrrrrmrrrr)rrrrrorqrrs@rr/r/se ,,,,,, ,,,,,,,,,,rr/r spdir_name current_dirr$T.Optional[T.Dict[str, T.List[str]]]T.Dict[str, T.List[str]]c|i}tj||}tj|s|St tj|dD]}tj|}|dkr(d}tj|rt|||n\|drEtj |r&tj |d}nd}|r&||vr|| ||g||<|S)N* packagecacheTz.wraprF) rrr#existsr}rQror?rr"r:r_)rrrsrspdirtrialrQ append_thiss rr?r?sA ~ GLLj 1 1E 7>>%  bgll5#..//++7##E** N " "  7==   z5& 9 9 9 9 ^^G $ $ )>)> w''11!4HHK  +6!!x ''....$)7x Mrsubstrstrlistc|D] }||vrdS dS)NTFr)r}r~rs rrsrss+  Q;;44  5rceZdZdZd d!dZd"d Zd#d Zd$dZd%dZd#dZ d&dZ d&dZ d'd(dZ d'd)dZ d*dZd+dZd*dZdS),r(zUA set that preserves the order in which items are added, by first insertion.
