pls

Implore a command to work.

Description

Run a specified command and open printed file/line numbers in your editor.

pls runs the utility given on the command line, and checks each line in the output for a file/line number. On termination of the utility, a file can be selected to open.

Examples

Run a make build and look for errors:
```
pls make
```
Run mocha tests and ignore system scripts in selection:
```
pls mocha -e
```
Run a make build task and specify a search path for opening files:
```
pls make -p src
```
Check for errors in a log file:
```
pls < errors.log
```

Compilation

pls requires the PCRE development headers, which can be installed using your system’s package manager, e.g.:

brew install pcre

apt-get install libpcre3-dev

With PCRE available a simple make should suffice.

Configuration

Editor

By default pls will try to infer how to open selected files based on your $EDITOR value, falling back on vim if it can’t recognise one.

You can specify an editor command using the $PLS environment variable. The first %d will be replaced with the line number, and the second %d with the column number (or 0 if not available). If a %s is present it will be replaced with the filename, otherwise the file will be appended to the end of the command.

For example:

vim +'call cursor(%d, %d)'

Patterns

A few line matching patterns are included by default, but more can be added by creating a ~/.plsrc file, with one regular expression pattern per line (with no delimiters).

A pattern should have up to 3 captures – the first being the filename, the second the line number, and the third the column number.

Options

-a: Show selection interface even if utility exits with 0 status
-l: Set initial selection to the last matched path
-e: Only select existing filenames Useful if build output may include system header files etc. which you don’t want to include in the selection list.
-p: Add path to the list of directories searched for selected files This can be used when files may be in include paths.
