fix(scraper): implement Priméo Énergie PDF parsing with TTC prices #64
Conversation
The scraper was extracting HT (hors taxes) prices but should use TTC (toutes taxes comprises) as shown in the PDF's lower table: - BASE kWh TTC: 0.1634€ (was 0.1327€ HT) - HP TTC: 0.1736€ (was 0.1434€ HT) - HC TTC: 0.1380€ (was 0.1147€ HT) HC/HP subscriptions now extracted from second price in concatenated PDF data (e.g., "15,4715,74" → TTC is 15.74€). Updated fallback values to match TTC prices from current PDF. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Pull request overview
This PR implements actual PDF parsing for the Priméo Énergie electricity price scraper, replacing the previous stub implementation that always fell back to default values. The implementation extracts TTC (all taxes included) prices instead of HT (before taxes) prices, and updates the fallback data accordingly.
Key changes:
- Implement
_parse_pdf,_extract_base_prices, and_extract_hc_hp_pricesmethods to parse PDF text using regex patterns - Update fallback prices from HT to TTC values (e.g., BASE kWh from 0.1562€ to 0.1634€)
- Add robust fallback mechanism that uses hardcoded TTC values if PDF extraction fails

- [nitpick] The same misleading description "20% de réduction sur le kWh HT vs TRV" appears here. Since the code now uses TTC prices, this description should be updated to match. This also affects the fallback offers at line 338 and 352.

- [nitpick] The offer description claims "20% de réduction sur le kWh HT vs TRV" (20% reduction on HT kWh vs TRV), but the code is now extracting and using TTC prices, not HT prices. This description is misleading since users will see the final TTC price, not the HT comparison. Consider updating the description to reflect TTC pricing or clarifying the HT discount is applied before taxes.

[nitpick] The regex pattern r"(\d+[,\.]\d{2})" only matches prices with exactly 2 decimal places. While this might be correct for the current PDF format, it could fail if prices have a different precision (e.g., "11.7" or "11.730"). Consider documenting this assumption or making the pattern more flexible with r"(\d+[,\.]\d{1,2})" if needed.

The comment states "The BASE subscriptions in the PDF are actually HT values" but then says "We use the values from the table (HT basis, same as display)". This is confusing because the PR description and fallback data comments state these should be TTC prices. The comment should clarify whether the extracted subscription prices are HT or TTC, and if they're HT, explain why they differ from the TTC values in the fallback data.

The comment states "15,47 is Primeo HT price for 6 kVA" and "15,74 is TRV/TTC price for 6 kVA", suggesting that the code extracts the second (TTC) price. However, this is inconsistent with the _extract_base_prices method which appears to extract the first price and assumes it's already TTC. This inconsistency suggests the subscription prices might not be correctly extracted as TTC in both methods. Please verify and ensure consistency in price extraction between BASE and HC/HP methods.

The price validation range 5 < price < 45 appears arbitrary and may be too restrictive or too broad. The actual BASE subscription prices range from 11.73 to 54.29 according to the fallback data, so a price of 54.29 would fail this validation. Consider using a more accurate range like 10 < price < 60 to match the actual expected price range.

[nitpick] The condition len(part) > 2 and "3 " in part[-5:] is redundant. If part[-5:] is being checked, then part must already have length > 2. Additionally, checking part[-5:] when length might be less than 5 could be clearer. Consider simplifying to just check if "3 " appears near the end of the part, or use a more explicit length check.

[nitpick] The same redundant condition pattern len(part) > 2 and "3 " in part[-5:] appears here. Additionally, string slicing part[-5:] could raise an error if the part is shorter than 5 characters (though Python handles this gracefully). Consider using a more robust pattern or at least simplifying the logic for consistency.

The code extracts the first price from each kVA part (price_match = re.match(r"(\d+[,\.]\d{2})", part)), which according to the HC/HP extraction logic would be the HT price, not TTC. However, the fallback values suggest these should be TTC prices. For example, the fallback has BASE 3 kVA at 11.73€, but if the PDF contains "8,51" followed by "11,73", the current logic would extract "8,51" instead of "11,73". This could result in incorrect (HT instead of TTC) subscription prices being extracted for BASE offers.

[nitpick] The comment states "The PDF structure concatenates values like: '8,516 kVA' where 8,51 is for 3 kVA." This seems incomplete or unclear. It suggests "8,51" is followed by "6" and "kVA", but doesn't explain what "8,51" represents or where it comes from. Consider providing a more complete example of the actual PDF text structure to make the parsing logic clearer.
| The PDF structure concatenates values like: "8,516 kVA" where 8,51 is for 3 kVA. | |
| The PDF structure presents subscription prices in a concatenated format, for example: | |
| "3 8,51 6 15,47 9 19,43 12 23,32 15 27,06 18 30,76 24 38,80 30 46,44 36 54,29 kVA" | |
| In this example, each pair of numbers corresponds to a power value (kVA) and its subscription price (in euros, using a comma as the decimal separator): | |
| - 3 kVA: 8,51 | |
| - 6 kVA: 15,47 | |
| - 9 kVA: 19,43 | |
| - 12 kVA: 23,32 | |
| - 15 kVA: 27,06 | |
| - 18 kVA: 30,76 | |
| - 24 kVA: 38,80 | |
| - 30 kVA: 46,44 | |
| - 36 kVA: 54,29 |

The regex pattern r"0[,\.]163\d" will match "0.163" followed by any single digit. This means it would incorrectly match "0.1639" or "0.1631" when you likely want to match specifically "0.1634". Consider using a more precise pattern like r"0[,\.]1634" or r"0[,\.]163[0-9]" with additional validation.

Similar to the BASE pattern issue, the regex patterns r"0[,\.]173\d" and r"0[,\.]138\d" will match any single digit after "173" or "138". This could incorrectly match values like "0.1735" or "0.1389" when you specifically want "0.1736" and "0.1380". Consider using more precise patterns like r"0[,\.]1736" and r"0[,\.]1380".
