# Problem Matcher
This library runs Problem Matcher definitions against an input and outputs any matches. These matches can then be used to add annotations etc to source code (like Github Actions does).
The inputs used for tests have been taken from problem matchers.
## Usage
```ts
import matcher from "https://github.com/scarf005/problem_matcher/blob/main/mod.ts"
const results = matcher(yourMatcher, input)
```
See below for `yourMatcher` format examples.
### Single Pattern
```javascript
const eslintSingleMatcher = {
owner: "eslint-compact",
pattern: [
{
regexp:
"^(.+):\\sline\\s(\\d+),\\scol\\s(\\d+),\\s(Error|Warning|Info)\\s-\\s(.+)\\s\\((.+)\\)$",
file: 1,
line: 2,
column: 3,
severity: 4,
message: 5,
code: 6,
},
],
}
const input =
"badFile.js: line 50, col 11, Error - 'myVar' is defined but never used. (no-unused-vars)"
const result = matcher(eslintSingleMatcher, input)
```
```json
[{
"file": "badFile.js",
"line": "50",
"column": "11",
"severity": "Error",
"message": "'myVar' is defined but never used.",
"code": "no-unused-vars"
}]
```
### Loop Pattern
```javascript
const eslintLoopMatcher = {
owner: "eslint-stylish",
pattern: [
{
// Matches the 1st line in the output
regexp: "^([^\\s].*)$",
file: 1,
},
{
// Matches the 2nd and 3rd line in the output
regexp: "^\\s+(\\d+):(\\d+)\\s+(error|warning|info)\\s+(.*)\\s\\s+(.*)$",
// File is carried through from above, so we define the rest of the groups
line: 1,
column: 2,
severity: 3,
message: 4,
code: 5,
loop: true,
},
],
}
const input = `test.js
1:0 error Missing "use strict" statement strict
5:10 error 'addOne' is defined but never used no-unused-vars
foo.js
36:10 error Expected parentheses around arrow function argument arrow-parens
37:13 error Expected parentheses around arrow function argument arrow-parens
✖ 4 problems (4 errors, 0 warnings)`
const result = matcher(eslintLoopMatcher, input)
```
`result`
```json
[
{
"file": "test.js",
"line": "1",
"column": "0",
"severity": "error",
"message": "Missing \"use strict\" statement",
"code": "strict"
},
{
"file": "test.js",
"line": "5",
"column": "10",
"severity": "error",
"message": "'addOne' is defined but never used",
"code": "no-unused-vars"
},
{
"file": "foo.js",
"line": "36",
"column": "10",
"severity": "error",
"message": "Expected parentheses around arrow function argument",
"code": "arrow-parens"
},
{
"file": "foo.js",
"line": "37",
"column": "13",
"severity": "error",
"message": "Expected parentheses around arrow function argument",
"code": "arrow-parens"
}
]
```
