Improve your code searching skills with pss
|
||
|
|
======
|
||
|
|
Searching a code base is a part of every day developer activities. From fixing a bug, to learning a new code base or checking how to call an api, being able to quickly navigate your way into a code base is a great skill to have. Luckily, we have dedicated tools to search code. Let's see how to install and use one of them - [**pss**][1].
|
||
|
|
|
||
|
|
### What is pss?
|
||
|
|
|
||
|
|
**pss** is a command line tool that helps searching inside source code file. **pss** searches recursively within a directory tree, knows which extensions and file names to search and which to ignore, automatically skips directories you wouldn't want to search in (for example `.svn` or `.git`), colors its output in a helpful way, and much more.
|
||
|
|
|
||
|
|
### Installing pss
|
||
|
|
|
||
|
|
Install **pss** on Fedora with the following command:
|
||
|
|
```
|
||
|
|
$ dnf install pss
|
||
|
|
```
|
||
|
|
|
||
|
|
Once the installation is complete you can now call **pss** in your terminal
|
||
|
|
```
|
||
|
|
$ pss
|
||
|
|
```
|
||
|
|
|
||
|
|
Calling **pss** without any argument or with the -h flag will print a detailed usage message.
|
||
|
|
|
||
|
|
### Usage examples
|
||
|
|
|
||
|
|
Now that you have installed **pss** let 's go through some Usage examples.
|
||
|
|
```
|
||
|
|
$ pss foo
|
||
|
|
```
|
||
|
|
|
||
|
|
This command simply looks for `foo`. You can be more restrictive and ask pss to look for `foo` only in python files:
|
||
|
|
```
|
||
|
|
$ pss foo --py
|
||
|
|
```
|
||
|
|
|
||
|
|
and for `bar` in all other files:
|
||
|
|
```
|
||
|
|
$ pss bar --nopy
|
||
|
|
```
|
||
|
|
|
||
|
|
Additionally, **pss** supports most of the well known source file types, to get the full list execute:
|
||
|
|
```
|
||
|
|
$ pss --help-types
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also ignore some directories. Note that by default, **pss** will ignore directories like .git, __pycache__, .metadata and more.
|
||
|
|
```
|
||
|
|
$ pss foo --py --ignore-dir=dist
|
||
|
|
```
|
||
|
|
|
||
|
|
Furthermore, **pss** also gives you the possibility to get more context from your search using the following :
|
||
|
|
```
|
||
|
|
$ pss -A 5 foo
|
||
|
|
```
|
||
|
|
|
||
|
|
will display 5 line of context after the matching word
|
||
|
|
```
|
||
|
|
$ pss -B 5 foo
|
||
|
|
```
|
||
|
|
|
||
|
|
will display 5 line of context before the matching word
|
||
|
|
```
|
||
|
|
$ pss -C 5 foo
|
||
|
|
```
|
||
|
|
|
||
|
|
will display 5 line of context before & after the matching word
|
||
|
|
|
||
|
|
If you would like to learn how to use **pss ** with regular expression and other options, more examples are available [here][2].
