logging - Translate Basic Config.groovy log4j DSL to external log4j.properties -

-

The following is a basic log4j configuration inside Config.groovy using log4j DSL with Grails 1.2, as it is expected Works (log errors: 'grails.app' root {error} Errors in the given file: 

  log4j = {appenders {file name: 'file', file: " C: /error.log "file '}} How will this be translated into a property style log4j configuration file? The following does not work:  
  Log4j.rootLogger = ERROR, fa log4j.appender.FA = org.apache.log4j.FileAppender log4j.appender.FA.File = C: /error.log Log4j.logger.grails.app = ERROR, FA  
 
 I suspect that there will be an error in 'translation of grails.app'  There is something along, but I do not really know, besides, the file can not be created, while with the first DSL version, it starts when the application starts. 
 
 If it does make any difference The property file is configured externally (though, the external log4j.groovy file works fine): 
 
  grails.config.locations = ["file: $ {baseir} / Ext Conf / log4j.properties "]  
 
 All I really want is an external log4j property file that logs all application exceptions to a file.

I believe the problem here is that to configure log4j, your property file Adding it is not being used through grails.config.locations will not just work.

An option is to keep log4j.properties on the classpath, for example 'Grails-app / conf in' directly. Check that it works, get the right to the configuration, and then locate the Lodge 4j documentation to find out how you can specify an alternate location for the property file. This may include setting up a system property.

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
