Collection of command line tools to work with properties files (diff-like, patch-like)
Project description
properties-tools
properties-tools is a collection of command line tools to work with properties files: comparing like wdiff
, updating like patch
...
The idea is to work with the content (key/value
pairs) instead of the text, to ignore order or format and deal with the data.
properties-diff
can compare and print differences between 2 properties files, with fancy colors as if you were usingwdiff
ordiff
tools. It does not compare the text files.properties-patch
can update a properties file using values from others, you can choose to add new keys and/or update existing and/or remove others.
Install
Install the latest release from PyPI
$ pip3 install properties-diff
$ properties-diff --help
Install from the sources
$ pip3 install --user --upgrade git+https://github.com/essembeh/properties-tools
$ properties-diff --help
properties-diff
Usage
$ properties-diff --help
usage: properties-diff [-h] [-q] [--quote] [--color | --nocolor] [--sep SEP] [-m {simple,diff,wdiff} | --diff | --wdiff | --simple] [-A] [-D] [-U] left.properties right.properties
positional arguments:
left.properties left file to compare
right.properties right file to compare
optional arguments:
-h, --help show this help message and exit
-q, --quiet print less information
--quote use double quotes for values, example: foo="bar"
--color force colors
--nocolor disable colors
--sep SEP key/value separator, default is '='
-m {simple,diff,wdiff}, --mode {simple,diff,wdiff}
select a format to show differences: using colors only (simple), using diff-like format (diff) or wdiff-like (wdiff) format. Default is 'wdiff'
--diff use diff-like format to show differences
--wdiff use wdiff-like format to show differences
--simple use simple format to show differences
-A, --added print added properties
-D, --deleted print deleted properties
-U, --updated print updated properties
Examples
Comparing properties files like wdiff
$ properties-diff tests/sample1.properties tests/sample2.properties
--- tests/sample1.properties (left) 2022-04-07 12:48:44
+++ tests/sample2.properties (right) 2022-04-07 12:49:02
# Only in tests/sample1.properties (left)
[-database.host=localhost-]
# Only in tests/sample2.properties (right)
{+database.version=12+}
# Updated from tests/sample1.properties (left) to tests/sample2.properties (right)
database.type=[-postgresql-]{+mysql+}
database.user=[-test-]{+dbuser+}
Comparing properties files like diff
$ properties-diff tests/sample1.properties tests/sample2.properties --diff
--- tests/sample1.properties (left) 2022-04-07 12:48:44
+++ tests/sample2.properties (right) 2022-04-07 12:49:02
# Only in tests/sample1.properties (left)
- database.host=localhost
# Only in tests/sample2.properties (right)
+ database.version=12
# Updated from tests/sample1.properties (left) to tests/sample2.properties (right)
- database.type=postgresql
+ database.type=mysql
- database.user=test
+ database.user=dbuser
Compare files, but only show updateed
and added
values
$ properties-diff tests/sample1.properties tests/sample2.properties --add --update
--- tests/sample1.properties (left) 2022-04-07 12:48:44
+++ tests/sample2.properties (right) 2022-04-07 12:49:02
# Only in tests/sample2.properties (right)
{+database.version=12+}
# Updated from tests/sample1.properties (left) to tests/sample2.properties (right)
database.type=[-postgresql-]{+mysql+}
database.user=[-test-]{+dbuser+}
Viewing modes
You can see differences between the properties files using 3 modes using --mode <MODE>
or -m <MODE>
wdiff
, prints the changes likewdiff
tool would do (this is the default mode)diff
, prints the changes likediff
tool would dosimple
, based on colors, red for removed lines, green for added lines
properties-patch
Usage
$ properties-patch --help
usage: properties-patch [-h] [--color | --nocolor] [-c] [-i] [--quote] [--sep SEP] [-A] [-D] [-U] -p patch.properties [-o output.properties | -w] [-f] source.properties
positional arguments:
source.properties file to modify
optional arguments:
-h, --help show this help message and exit
--color force colors
--nocolor disable colors
-c, --comments insert comment when property is added, updated or deleted
-i, --interactive ask for confirmation to add, update or delete a property
--quote use double quotes for values, example: foo="bar"
--sep SEP key/value separator, default is '='
-p patch.properties, --patch patch.properties
patch file
-o output.properties, --output output.properties
modified file
-w, --overwrite update input properties file in place
-f, --force force output file (--output) overwrite if it already exists
-A, --add add new properties from patches
-D, --delete delete properties not in patches
-U, --update update properties from patches
Examples
Build a properties file from tests/sample1.properties
and add missing keys from tests/sample2.properties
$ properties-patch tests/sample1.properties --patch tests/sample2.properties --add
# just a comment
database.type=postgresql
database.host=localhost
database.port=5432
# and another comment
database.user=test
database.password=foobar
database.version=12
You can use multiple patch files, if a value is present in multiple patch files, the latest value will be used.
$ properties-patch tests/sample1.properties --patch tests/sample2.properties --patch tests/sample3.properties -A
# just a comment
database.type=postgresql
database.host=localhost
database.port=5432
# and another comment
database.user=test
database.password=foobar
database.version=42
You can choose to add missing values and update values that are different in the patch files
$ properties-patch tests/sample1.properties --patch tests/sample2.properties -AU
# just a comment
database.type=mysql
database.host=localhost
database.port=5432
# and another comment
database.user=dbuser
database.password=foobar
database.version=12
There is an interactive mode, which ask for confirmation before every change (usefull to take only some changes, equivalent to git add --interactive
)
$ properties-patch tests/sample1.properties --patch tests/sample2.properties -AU --interactive
# just a comment
💬 Update database.type=postgresql,mysql ? [Y/n]
database.type=mysql
database.host=localhost
database.port=5432
# and another comment
💬 Update database.user=test,dbuser ? [Y/n]
database.user=dbuser
database.password=foobar
💬 Add database.version=12 ? [Y/n]
database.version=12
To track changes, you can add comments for every change applied
$ properties-patch tests/sample1.properties --patch tests/sample2.properties -ADU --comments
# just a comment
# 2022-04-07 23:12:11 update: database.type=postgresql
database.type=mysql
# 2022-04-07 23:12:11 remove: database.host=localhost
database.port=5432
# and another comment
# 2022-04-07 23:12:11 update: database.user=test
database.user=dbuser
database.password=foobar
# 2022-04-07 23:12:11 add: database.version
database.version=12
