<filemasks> Specifies the file masks or file names to process.
/? Displays help. /S Search this directory with all subdirectories. /Y Modify also read-only files. /B:0 if .bak file exists no replace will be performed (default). /B:1 if .bak file exists, it is overwritten. /B:2 No .bak file is created. /Q Quiet operation. No output to console.
/I Ignore case. /W Whole words. /L Multi line search. /P Perl RegEx search pattern. /R Perl RegEx replacement pattern. /X Specifies rule file with multiple Perl RegEx search and replace patterns or rules.
The rule formats: #unuse <unit> - remove unit from the PAS uses clause #remove <property> - remove property from PAS and DFM #migrate [<class> :] <old> -> <new> [, <unit>] - replace old with new identifier, optionally add unit to uses clause, optionally restrict migration to the specified class
Each file line has format: <searchpattern> -> <replacepattern> Patterns Format reFind uses Perl compatible regular expressions (PCRE) for search and replacement patterns.
Seach and Replace Rule <search pattern> -> <replace pattern> <Search pattern> is a PCRE search pattern. <Replace pattern> is a PCRE replace pattern.
Remove Unit Rule #unuse <unit name> Removes the specified <unit name> from the interface and the implementation section of the "uses" clauses of the PAS files.
Remove Property Rule #remove <property name> Removes the specified <property name> from PAS and DFM files. From a PAS file, it will remove any construction like <prop> := <value>;.
Migrate Rule #migrate [<class> :] <old name> -> <new name> [, <unit>] Replaces all <old name> identifiers with a <new name> in PAS and DFM files. If the <class> is specified, then the rule will be applied only to the objects of the specified class:
DFM - only to base objects, not to inherited ones; PAS - only to <obj>.<old name> constructions, not to the "with" clauses content. If the <unit> is specified, then it will be added to the "uses" clause of the PAS unit part, where the <old name> is found. The <unit> may be a comma-separated list of the units.
Examples Replace all "TQuery" with "TFDQuery" in pas files : refind *.pas /I /W /P:TQuery /R:TFDQuery Replace all "TxxxQuery" with "TFDQuery" in pas and dfm files : refind *.pas *.dfm /I /W "/P:T[A-Za-z]+Query" /R:TFDQuery Replace all "TxxxQuery" with "TQueryxxx" in pas and dfm files : refind *.pas *.dfm /I /W "/P:T([A-Za-z]+)Query" /R:TQuery\1 Remove all "Origin = xxxx" from DFM files : refind *.dfm /L "/P:\n +Origin =.+$" "/R:" Migrate application from BDE to FireDAC: reFind *.pas *.dfm /X:FireDAC_Migrate_BDE.txt See Also Regular Expressions GREP.EXE, the text search utility Search Menu Migrating AnyDAC Applications to FireDAC Migrating BDE Applications to FireDAC Migrating dbExpress Applications to FireDAC Category: XE5
