LRM supports a number of file types out of the box (See Supported Resource Bundles). However, other file types may represent user facing strings to be translated. In that case, some customization is required to on-board those projects. The bash script transform framework facilitates the customization.

Analyze the file types

If the file types fall into a category not supported by LRM out of the box, the first thing to do is to see what is the closest file types supported by LRM.

Use the transform framework

The transform framework needs three scripts in order to fit in with LRM. The three scripts need to be under the $JENKINS_HOME/lingoport/transform/<nameoftransform>/ directory.


The <nameoftransform> must be indicative of the type of transformation to apply. For instance, it could be loc to handle .loc files (see below). In that case, three scripts will need to be under /var/lib/jenkins/lingoport/transform/loc for a typical installation where the jenkins user is under /var/lib/jenkins.


The three scripts to write are:

  • transform_from_repo.sh: How to transform the files from the repository so they fit into an LRM supported file type
  • transform_to_repo.sh: How to transform translated/pseudo-localized files in an LRM supported file type into the repository file type
  • transform_files_list.sh: How to transform the file names from the LRM supported file naming into the repository file naming


When those scripts are written, the transformation is defined in the config directory of the on-boarded project with the transform.properties. This file contains one properties, 'transform'. For instance, if loc is the directory with those three scripts under $JENKINS_HOME/lingoport/transform/ for a <PROJECT> under a <GROUP>, the file will be:


$JENKINS_HOME/Lingoport_Data/L10nStreamlining/<GROUP>/projects/<PROJECT>/config/transform.properties

transform=loc

Bash Variables

Depending on the transformation scripts, some bash variables may need to be set.

  • CLIENT_SOURCE_DIR : For an LRM project such as CET.json, the CLIENT_SOURCE_DIR would typically be ~jenkins/jobs/CET.json/workspace. Note: This is not necessarily the WORKSPACE of the running Jenkins job from which the transform is called (Dashboard Update for instance).
  • LRM_PROJECT_NAME : this may need to be set if secondary jobs like LRMCriticalErrors are called with transform
  • LRM_GROUP_NAME : this may need to be set if secondary jobs like LRMCriticalErrors are called with transform

Example: .loc files

Say the repository contains resource files like the following hmUiMessage.loc file:

;hmUiMessage.loc
;*********************************************************************
#include hmUiMain.loc
;*********************************************************************
message1	The first message
message2	The second message
message3	The third message
message4	The fourth message

The file may not be in ASCII or UTF-8 format; For instance this file is in UTF-16BE

A supported file format that is close to this one is properties.

transform_from_repo.sh

An example snippet of bash code for this type of file may be something like:

#!/bin/bash

# Find all the files ending in 'loc'
find $CLIENT_SOURCE_DIR -name "*loc" > ~/tmp/input_files.txt

# Transform each .loc file into a .properties file
cat ~/tmp/input_files.txt | while read -r FILEPATH
do
  FILENAME=`basename $FILEPATH`
  DIRNAME=`dirname $FILEPATH`
  file "$FILEPATH"
  SUFFIX=".loc"
  ROOTNAME=${FILEPATH%$SUFFIX}
  TARGET="${ROOTNAME}.properties"
  iconv -f UTF-16 -t UTF-8 -c "$FILEPATH" > "$TARGET"
  sed -i 's/^#/# #/' "$TARGET"
  sed -i 's/^;/# ;/' "$TARGET"
  sed -i -e "s/[[:space:]]\+/=/" "$TARGET"
  sed -i -e "s/^=$//" "$TARGET"
done

transform_to_repo.sh

An example snippet of bash code for this type of file may be something like:

#!/bin/bash

# Find all the files ending in .properties
find $CLIENT_SOURCE_DIR -name "*.properties" > ~/tmp/input_files.txt

#
# Transform each .properties into a .loc
#
cat ~/tmp/input_files.txt | while read -r FILEPATH
do
  FILENAME=`basename $FILEPATH`
  DIRNAME=`dirname $FILEPATH`
  ls -l "$FILEPATH"
  SUFFIX=".properties"
  ROOTNAME=${FILEPATH%$SUFFIX}
  TARGET="${ROOTNAME}.loc"
  cp "$FILEPATH" "$TARGET"
  sed -i 's/^#=#/#/' "$TARGET"
  sed -i 's/^#=;/;/' "$TARGET"
  sed -i -e  "s/^#\([[:alnum:]]*\)/;\1/" "$TARGET"
  sed -i -e  "s/\([[:alnum:]]*\)=/\1\t/" "$TARGET"
  iconv -f UTF-8 -t UTF-16 -c "$TARGET" > tmp.tmp
  mv tmp.tmp "$TARGET"
done

transform_files_list.sh

An example snippet of bash code for this type of file may be something like:

#!/bin/bash
# Check if there is a parameter
if [ -z "$1" ]
  then
    echo "Error: Missing the argument like /<path>/pseudo_files.txt"
    exit 1
fi

# If the file exists then do something, otherwise exit
if [ -f "$1" ]; then
    echo " File to rewrite: $1"
else
    echo " $1 not found"
    exit 1
fi

# Rename .properties to .loc files inside the list of files passed as a parameter
sed -i 's/\.properties/.loc/' "$1"
