Name

condor_transform_ads — HTCondor Manual

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
