condor_transform

condor_transform_ads

Transform ClassAds according to specified rules, and output the transformed ClassAds.

Synopsis

condor_transform_ads [-help [rules]]

condor_transform_ads -rules rules-file [-in[:<form>] infile] [-out[:<form>[, nosort]] outfile] [<key>=<value>] [-long] [-json] [-xml] [-verbose] [-terse] [-debug] [-unit-test] [-testing] [-convertoldroutes] [infile1 …infileN]

Note that exactly one rules file, and at least one input file, must be specified. If no output file is specified, output will be written to stdout.

Description

condor_transform_ads reads ClassAds from a set of input files, transforms them according to rules defined in a rules file, and outputs the resulting transformed ClassAds.

See https://htcondor-wiki.cs.wisc.edu/index.cgi/wiki?p=TjsAdTransformLanguage for a description of the transform language.

Options

-help [rules]

Display usage information and exit. -help rules displays information about the available transformation rules.

-rules rules-file

Specifies the file containing definitions of the transformation rules.

-in[:<form>] infile

Specifies an input file containing ClassAd(s) to be transformed. <form>, if specified, is one of:

long: traditional long form (default)
xml: XML form
json: JSON ClassAd form
new: "new" ClassAd form without newlines
auto: guess format by reading the input

If - is specified for infile, input is read from stdin.

-out[:<form>[, nosort] outfile

Specifies an output file to receive the transformed ClassAd(s). <form>, if specified, is one of:

long: traditional long form (default)
xml: XML form
json: JSON ClassAd form
new: "new" ClassAd form without newlines
auto: use the same format as the first input

ClassAds are storted by attribute unless nosort is specified.

[<key>=<value>]

Assign key/value pairs before rules file is parsed; can be used to pass arguments to rules. (More detail needed here.)

-long

Use long form for both input and output ClassAd(s). (This is the default.)

-json

Use JSON form for both input and output ClassAd(s).

-xml

Use XML form for both input and output ClassAd(s).

-verbose

Verbose mode, echo transform rules as they are executed.

-terse

Disable the -verbose option.

-debug

More information needed here.

-unit-test

More information needed here.

-testing

More information needed here.

-convertoldroutes

More information needed here.

Exit Status

condor_transform_ads will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

Examples

Here’s a simple example that transforms the given input ClassAds according to the given rules:

  # File: my_input
  ResidentSetSize = 500
  DiskUsage = 2500000
  NumCkpts = 0
  TransferrErr = false
  Err = "/dev/null"

  # File: my_rules
  EVALSET MemoryUsage ( ResidentSetSize / 100 )
  EVALMACRO WantDisk = ( DiskUsage * 2 )
  SET RequestDisk ( $(WantDisk) / 1024 )
  RENAME NumCkpts NumCheckPoints
  DELETE /(.+)Err/

  # Command:
  condor_transform_ads -rules my_rules -in my_input

  # Output:
  DiskUsage = 2500000
  Err = "/dev/null"
  MemoryUsage = 5
  NumCheckPoints = 0
  RequestDisk = ( 5000000 / 1024 )
  ResidentSetSize = 500
