Everything ceelab does

Version described: ceelab 0.3.3. Every screenshot comes from the application itself.

Generation

  • Filterable list of all document types; the last one chosen is remembered on the computer.
  • One line per field asked of the operator; errors appear under the field, and a counter shows its next number.
  • Lines build up in the batch, which can mix several types; preview without using anything up.
  • Earlier date: the documents, the PDF metadata and the counter period follow the chosen date.
  • The button tells you what will come out: “Print 12 labels”, “Generate 12 documents”.
  • Keyboard: Enter moves to the next field and adds the line on the last one; Ctrl+Enter generates; Ctrl+N clears the batch.
Generation window: a two-line batch, the form of a product label, and the Generate 13 documents button.Generation window: a two-line batch, the form of a product label, and the Generate 13 documents button.

End of generation and first-label check

  • Numbers are reserved and every document is recorded in the history in a single operation.
  • Parallel compilation, then all the labels of the batch go to the spooler at once, in order.
  • For each document: Preview, Open PDF (documents), Reprint and 180° Rotate (labels), without using up a number.
  • With the first batch of labels, only one is printed for checking (orientation, alignment, content) before the rest of the batch; this check happens once per installation.
End-of-generation screen: four documents, their printed labels and the saved delivery note.End-of-generation screen: four documents, their printed labels and the saved delivery note.

Document types and fields

  • Eight field kinds: text, number, date, choice list, Yes/No, counter, combined, formula.
  • Options: required, asked of the operator or fixed value, default value.
  • Each field has a variable in English, {product}; “Rename the variable” updates everything that refers to it.
  • Document language set per type: dates and hyphenation in the documents produced.
  • Pattern for PDF file names, with a live preview.
Document types tab: Address field on multiple lines, Weight, Fragile (Yes/No), Parcel no. (counter) and Parcel code (formula).Document types tab: Address field on multiple lines, Weight, Fragile (Yes/No), Parcel no. (counter) and Parcel code (formula).

Counters

  • Numbers reserved in blocks, in one atomic operation; the numbers of a batch are contiguous, with no ceiling.
  • Reset never, every year, every month or every day, based on the document date.
  • A reserved number is always traced: a failed output is regenerated with the same number.
  • Example: 2026-10-0042 comes from a counter reset every month and the combined field {year}-{month}-{serial}.

Formulas and conditions

  • A text with gaps {…}, each gap being an expression: {prefix}{format_date(date, "yymmdd")}-{pad(rank, 2)}.
  • Functions text, number, round, decimals, pad, upper, lower, left, right, replace, format_date, add_days and lookup; operators, comparisons and if … then … else.
  • Checks on saving: unknown names, incompatible types, circular calculations, with the result on the sample values.
  • A formula that fails blocks generation without using up a number; results are frozen in the history.
  • The same expressions can be written in template texts.
Formula field {year}-{parcel}: result on the sample values, fields used, templates that use it and available elements.Formula field {year}-{parcel}: result on the sample values, fields used, templates that use it and available elements.

Template lab

  • Text elements, images, shapes, lines, CE and ATEX markings; label of any size or A4 page.
  • The “Insert a variable” palette offers the fields of the type and the ceelab elements ({date}, {copy}, {location}…).
  • Several templates per type; those checked “Produced on every generation” come out for each copy.
  • Drafts saved automatically, .ceet import and export, import of Word and ODT documents.
Template editor: layer list, 4 × 2 in product label with its variables, properties of the selected element.Template editor: layer list, 4 × 2 in product label with its variables, properties of the selected element.

Template gallery

  • Gallery filterable by type, “Not attached” included, with a fitted preview and sample values.
  • Edit, duplicate, export, attach to a type.

History and database

  • History by batch, accent-insensitive search, status of each output.
  • Identical regeneration: same values, same language, same date, same original layout, no number used up.
  • Excel export of the filtered history.
  • Database table explorer, Excel import and export, import of a .db database.

Settings and backup

  • Interface language, output folder, location ({location} variable), label and document printers.
  • Backup as a ZIP archive (database and settings) and full restore.

Protected access

  • Administration is protected by a password set on first launch and asked once per session.
  • Five failed attempts send you back to generation mode, with a deliberate delay after each incorrect attempt.
  • The password is never stored in plain text; if you forget it, it can be reset (see the guide).

The cee command line

  • Commands types, describe, preview, print, history, reprint and edit.
  • The -- options depend on the variables of the type: --product "Stainless screw" or --set product="Stainless screw".
  • JSON response (--json) and stable exit codes, for scripts and scheduled tasks.
  • Same safeguards as the application, all checked before a single number is reserved.

Platforms

  • Windows (x64), macOS (Apple Silicon) and Linux (.deb package).
  • The Typst rendering engine is built in: nothing else to install.
  • Batch printing on Windows with built-in SumatraPDF; CUPS (lp) elsewhere.
