REPORTING SPECS CASES 1734 - REPORTS:GRIDS: - grid filter name and summary of filter criteria available as fields to print on report REQUIREMENTS - All v7 reports ported to RAVEN - ALL Fields even the ones that don't show on the report but are available for adding to a report in the editor need to be available - REPORTS - Report object has following properties: - DataList name it's based off of - Required fields from DataList - Report template itself with it's own code and template requirements TBD - Report columns returned: When user selects to show a report, client will fixup any missing columns from the datalistview currently in use - For example they are viewing a table based on a TestWidgetDataList DataListview with only 3 columns in it - They drop down the reports list which shows all reports based off TestWidgetDataList view - They select a report to print. - Report code looks at report's required fields from DatalistView and sees report uses 6 fields listed - Code compares report fields to in use DataListview fields and appends any report required fields missing from current view to the right of the collection in the current DataListview - When report is run it will have all fields this way returned but will still be sorted and filtered by table view - As part of editing process user can select an existing datalistview to prime their report editing view - A report can be selected from any client table that is based on the same view //======================= USEFUL REPORTING RELATED LINKS https://github.com/jsreport/jsreport-core https://github.com/jsreport/jsreport-core/blob/master/lib/render/engineScript.js //actual render here https://github.com/jsreport/jsreport-chrome-pdf/blob/d3fe318aac3628d8cb62f86f8f71314f21745798/lib/conversion.js //PDF utils https://github.com/jsreport/jsreport-pdf-utils They use a Mozilla library called pdfjs and their utils are basically just wrappers around using it https://github.com/mozilla/pdf.js hub to docs here: https://mozilla.github.io/pdf.js/ This is the jsreport designer libs used for reference: https://github.com/jsreport/jsreport-studio/blob/master/package.json https://jsreport.net/learn/api Report templates pre-designed and open source: https://github.com/wildbit/postmark-templates HTML -> PDF JSREPORT has a comparison table of various html to pdf tools here: https://jsreport.net/learn/pdf-recipes Headless Chrome https://github.com/jsreport/jsreport-chrome-pdf FAST SPEED (according to jsreport docs) jsreport uses headless chrome by default which has built in pdf from html ability. they use a NODE library Puppeteer for it, but there is a c# wrapper for .net core linux windows mac: https://github.com/hardkoded/puppeteer-sharp some kind of example that may be relevant: https://github.com/kblok/netconfar-puppeteer-sharp-demo/blob/master/hacking-the-browser-api/Controllers/MediumController.cs#L13 Maybe not the only one for c# core, need to dig around Issues: Issue with header / footer not being settable apparently which is a big breaking issue for many biz reports usage someone said that another pdf tool can be used to set those post processing but fuckery abounds other solutions below apparently don't have this issue. Even jsreport has listed workarounds and tools to resolve this Update: apparently there are ways: https://stackoverflow.com/questions/44575628/alter-the-default-header-footer-when-printing-to-pdf?noredirect=1&lq=1 see last comment seems relevant, also other linked cases all mention various things. Finally, could use a pdf writer tool to post process maybe. There seem to be many potential issues with missing libraries, rights and sandbox and etc etc etc on linux These things kind of turned me off this a bit, it's not plug and play and simple LINKS: https://github.com/hardkoded/puppeteer-sharp https://github.com/puppeteer/puppeteer https://stackoverflow.com/search?q=puppeteer-sharp https://stackoverflow.com/questions/62042078/puppeteer-sharp-for-server-side-html-to-pdf-conversions https://www.singlestoneconsulting.com/blog/how-to-generate-server-side-pdf-reports-puppeteer-d3-handlebars/ https://github.com/hardkoded/puppeteer-sharp/issues/1510 - shows being used by someone other than jsreport which buries all the details in endless libs https://github.com/hardkoded/puppeteer-sharp/issues/1514 WeasyPrint https://github.com/jsreport/jsreport-weasyprint-pdf SLOWEST SPEED https://github.com/Kozea/WeasyPrint based on python, does it's own rendering doesn't rely on a web browser engine like the rest free, recommended by wkhtmltopdf author as an alternative May be slow, slower than the other options likely, has some installation steps that are a bit convoluted but ironically only for windows as it's included in package managers Very good support for modern css3 PAGE properties apparently WRAPPER https://github.com/balbarak/WeasyPrint-netcore/blob/master/src/Balbarak.WeasyPrint/WeasyPrintClient.cs wkhtmltopdf https://github.com/jsreport/jsreport-wkhtmltopdf MEDIUM SPEED https://wkhtmltopdf.org/downloads.html Well used, old based on older webkit so doesn't support css3 but likely enough for our purposes has an easy installer for all platforms free Has warnings about how unsanitized html can take down a server or own it somehow WRAPPERS https://github.com/carloscds/HtmlToPDFCore/tree/master/HtmlToPDFCore This one looks cool, all platforms supported includes binary possibly? https://blog.elmah.io/generate-a-pdf-from-asp-net-core-for-free/ HTML -> DOCX This is a possiblity that needs to be researched, instead of pdf go docx which is in theory multi platform and openable on other devices?
